The integrated odor treatment device using the built-in high-efficiency deodorizing combination scrubber system is a odor treatment device consisting of a charging part, a wet treatment part, a mist removal part, and an adsorption treatment part, which is located above the mist removal part and oxidizes the odor introduced into the odor inlet. While supplying ozone for the purpose, there is a technical feature to further include an ozone generator for using the heat emitted when ozone generation in the ozone discharge tube to lower the relative humidity contained in the odor passed through the wet treatment.
&#;&#; &#;&#;&#; &#;&#;, &#; &#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;(&#;&#;&#;&#; &#;12&#;07&#;) [&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;]&#; &#;&#;&#;,As a technology for efficiently treating various odors, that is, gas pollutants, Patent Registration No. (December 7, ) [Integrated odor treatment apparatus using a highly efficient deodorizing combination scrubber system with an ozone generator] there is,
&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;. &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;. The adsorption method can handle most odorous substances and the efficiency is determined by the replacement cycle of the adsorbent. However, there is a problem that the cost of activated carbon replacement and excessive cost in the treatment of high concentration odor.
&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;. &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;. In addition, the biofilter method has a low maintenance cost and shows very high processing efficiency for some materials. However, there are disadvantages in that the installation area is large and the biological treatment of the material is difficult.
&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;. &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;. &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;. For example, the chemical liquid cleaning method has the advantage of being suitable for the treatment of water-soluble odorous substances, inexpensive installation cost, and dust treatment. The chemical cleaning method determines the efficiency according to the replacement cycle of purified water. However, there is a disadvantage in that the treatment water cost is generated and the water-insoluble odor treatment is difficult.
&#;&#;, &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;, &#;&#;&#;, &#;&#;&#;&#;&#;&#;, &#;&#;&#; &#;&#;&#;, &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;, &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;.On the other hand, there are soil deodorization method, adsorption method, microbial treatment method, biofilter method, general cleaning method and the like as the treatment method of odor generated in the conventionally known biological water treatment facility and the like, each of which has advantages and disadvantages.
&#;, &#;&#;&#; &#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;, &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;. &#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;. In other words, simply covering each reaction tank of each process, collecting air in the cover and treating it in the odor treatment facility such as a biofilter is because the amount of air collected in the reaction tanks of each process is too large and a large blower at the rear stage And biofilters. This in turn puts an economic burden on operators.
&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;, &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#; &#;&#; &#; &#;&#;&#;, &#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;. This non-selective, nondiscriminatory, and unplanned approach would theoretically be able to completely reduce odors and reduce the aversion and damage caused by odors, but in reality, roofs and covers are installed on all reactors, both new and existing. This is impossible in terms of cost or operation and management of water treatment facilities, and it is difficult to apply in practice.
&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;,As such, in the conventional biological water treatment facilities, roof-like covers are installed in various reactors as much as possible, pipes and pumps are installed on the covers, and the odor is only buried in the method of collecting and treating odors.

Process, A2 / O process, UCT and VIP. Simultaneous removal of nitrogen and phosphorus can be done using the Modified Bardenpho process, the A2 / O process with an additional denitrification filter, and the UCT process. Particularly, in order to remove more than 80% of phosphorus, coagulation removal using the Phostrip process has been suggested as the most reliable method. For example, if you want to remove more than 85% of nitrogen, you can choose the four-stage Bardenpho process as the BNR process. If you want to remove phosphorus, you can remove nitrogen and phosphorus simultaneously by adding chemical flocculation sedimentation process.

Particularly, in the case of applying domestic technology by introducing foreign technology rather than domestically developed technology, macroscopic environmental condition and operating condition are not a problem, but the treatment water quality and process efficiency are determined according to the microscopic environment and operation condition. As such, it is necessary to improve and supplement existing plants in various forms or approaches.

The deposition growth process is classified not only by media type, shape and filling method, but also by process type depending on whether the media is fluid or stationary and filled with 60% or more of the effective volume of the reactor. Representative deposition growth processes include sprinkling water phase, RBC, fluidized bed, and fixed bed reactors, and the existing treatment sludge process can be converted to nutrient removal process to operate the existing treatment plant according to the operating conditions, shape, and process arrangement of each reactor. In addition, it is possible to obtain benefits such as increasing treatment capacity and ensuring stable treatment water quality depending on the type of medium, filling rate, and specific surface area.

When sent to the odor treatment facility can be effectively treated odorous substances. The same applies to all other processes where the aeration device repeats on and off.
&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#; &#;&#; 30&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; 54%&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;.The results show that the amount of odorous substances contained in the air collected by the first 30 minutes after the start of the aeration phase is 54% of the total amount of odorous substances released in one cycle of aeration.
&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#;, &#;&#;&#; &#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#; &#;&#;&#;&#;&#; &#;&#; 120&#;, &#;&#;&#;&#; 100&#;, &#; &#;&#;&#;&#; 80&#;, &#;&#; &#; &#;&#;&#;&#; 60&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;, &#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; 40&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;, &#; &#;&#; &#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; 30&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;.For more reliable odor capture and treatment, and considering the circumstances of batch biological water treatment systems with varying environments and capacities, the present invention provides an initial 120 minutes, limited 100 minutes, more limited 80 minutes, even more limited 60 minutes It is preferable to proceed, and more preferably, the odor gas collection may proceed for the first 40 minutes of the aeration stage, and even more preferably, the odor gas collection may proceed for the first 30 minutes of the aeration stage.

In particular, the reaction tank (T1) is equipped with an Oxidation Reduction Potential (ORP) sensor for measuring the redox potential value of water containing oxides. It is desirable to increase the removal of odors. The increase and decrease of the odor collection amount can be implemented by increasing or decreasing the odor transfer amount by a pump or a blower provided in the odor transfer pipe.

The head space gas (head space gas), that is, the odor source, is preferably processed through the conventional biofilter unit 20 and the adsorption treatment unit 30, which are subsequent odor treatment means, through forced transfer by a pump rather than a natural flow. In particular, it is preferable to be transported to the odor treatment means equipped with the following odor active monitoring function applied to the water treatment system of the present invention described below with respect to FIGS. In addition, if necessary, the concentrated selective odor collecting means may be provided with a separate TRS sensor (S).
&#;&#;, &#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;, &#;, &#;&#;&#;(continuos) &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#; &#;&#;.
On the other hand, biological water treatment system having a concentrated selective odor collecting means according to the present invention can be basically applied to a system having a separate aeration tank, that is, a water treatment system applying a continuous biological water treatment method.

The creation and development of sewerage is in the same history as the creation and development of cities. As the population grows and the city grows in size, water usage increases and sewage generation increases at the same rate. Therefore, there is a need for a sewerage system that can effectively treat increased sewage.
&#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;·&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#;&#;·&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;·&#;&#;&#;&#;·&#;&#;&#;&#;&#;&#;&#;&#;&#; &#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;. &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;(&#;&#;&#;, , &#;&#; 30&#;&#;). &#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#; 22&#;&#;&#;&#; &#; 357&#;&#;, &#;&#;&#;&#;&#;&#;&#; 35.7%&#;&#; 87.1%, &#;&#;&#;&#;&#;&#; &#;&#; 85.8%&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#; 23,273&#; &#;&#; &#;&#;&#; &#;&#;. Sewage is a public sewage system, which is installed or managed by local governments, and small and medium, sewage, and personal sewage installed by the installer or owner of a building or facility to discharge or treat sewage from the building or facility. There is a 'personal sewer' that refers to a treatment facility and its associated facilities. As urban areas have a high population density and almost close distances between houses, sewage systems that collect sewage through sewage pipes and concentrate them in sewage treatment facilities are environmental and economical (Ministry of Environment, , 30-year history). In the meantime, the government has made steady efforts in 22 sewage treatment plants in , 357 in , sewage supply rate from 35.7% to 87.1%, sewage treatment rate of 85.8% in , and 23,273 thousand tons per facility capacity. .
&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;, &#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;. &#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#; &#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;. As the economic level gradually increased, citizens pursued a more comfortable life, and the odor generated from the sewage treatment process became recognized as a 'resident hate facility'. In addition, when construction of a new sewage treatment plant or expansion of an existing treatment plant was encountered, the installation was often delayed due to severe opposition from the local residents.
&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#; &#;07&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#; 4,797&#;&#; &#;&#;&#;&#;&#; &#; 4,302&#;&#; &#;&#; &#; 11. 5%&#; &#;&#;&#;&#;&#;. According to the data from the Ministry of Environment's analysis of odor complaints and directions for odor management in , a total of 4,797 cases of odor complaints occurred nationwide in , up 11.5% from 4,302 cases in . .
&#;&#; &#;&#;, &#;&#; &#;&#;&#;, &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#; &#;&#;&#; &#;&#;&#;, &#;&#;&#;, &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#; &#; &#;&#; &#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;.There are various wastewaters such as livestock wastewater, commercial wastewater, and septic tank wastewater, and there are various treatment methods and facilities for treating them, but there is a need for living sewage that occurs inevitably in residential areas, especially around the city, and causes the most direct and immediate situation in life. Treatment facilities are critical, and for this purpose, the elimination of odors from generalized biological water treatment systems is also more urgent than ever.
&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;, &#;&#;, &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#; &#; &#;&#;&#;&#;&#; &#;, &#;&#; &#;&#;&#; &#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#; &#;&#;&#;&#;&#;&#;&#;&#;(VSCs)&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;, &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;.Therefore, sewage pipes and various sewage, sewage, and wastewater treatment plant odors are of great interest in modern society. Among the various odorous substances emitted from various sewage and treatment facilities, volatile sulfur compounds (VSCs) are known as major odorous substances. It is important to reduce the emissions of volatile sulfur compounds from wastewater and sewage treatment plants.
&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;, &#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#;&#;&#;, &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;, &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;, &#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; TRS &#;&#;&#;&#;(Online TRS Analyzer)&#; &#;&#;&#;&#; &#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#; &#;&#; &#;&#;, &#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;.The development and introduction of odor treatment facilities that meet or exceed odor emission standards is also important.However, it is necessary to devise real-time monitoring and operation methods for timely response to odor occurrence in biological water treatment facilities. The inventors conducted research on where to collect the collecting means, and achieved the desired results. In connection with this result, the online TRS analyzer was installed at the boundary area of sewage pipe and sewage treatment plant in real time. Invented a way to monitor and respond immediately when odor occurs, that is, odor treatment system equipped with active odor monitoring.
&#; &#; &#;&#;&#;&#; &#; &#; &#;&#;&#; &#;&#;&#; A2O &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;(continuos) &#;&#;&#;&#; &#;&#;&#; &#;&#; &#; &#;&#;&#;(batch) &#;&#;&#;&#; &#;&#;&#; &#;&#;, &#;&#; &#;&#;&#;/&#;&#; &#;&#;&#;(AAA: alternative anoxic aerobic) &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;, &#;&#; &#;&#;&#;&#;&#; &#;&#; &#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;.
In addition, the present research results and the concept of the present invention are activated sludge applying continuous biological water treatment method and batch biological water treatment method represented by A2O method, in particular anoxic / aerobic alternating method (AAA). Research and invention achievements have also been made to the odor trapping and treatment system generated in the reactor.
&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#; TRS &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;Experiment to verify the effectiveness of reducing odor reducing agent in sewage pipe and effectiveness of TRS analysis equipment

As a result of evaluating sewage odor reduction efficiency before and after the first spraying,
&#;&#;&#; &#;&#;&#; &#;&#; &#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#;. It was found that the effectiveness of the odor reducer spraying in the market, which is considered as a odor reduction measure in roadside manholes and rain gutters in Seoul, did not have a significant effect.
&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;.
Therefore, in general, there was no reduction effect of odor reducing agent in sewage pipe.

Nevertheless, the effectiveness of the TRS analysis equipment has been proved, and the research on the odor emission characteristics, the odor collection and treatment method using the TRS analysis equipment in other sewage treatment facilities, especially the sewage treatment plant, was found to be effective.
&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; - &#;&#; &#;&#; &#; &#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;Actual organic waste treatment plant-Odor characteristics test for each odor type and each reaction unit process

&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;, &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;, &#; &#;&#; 7,300&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#; 2,000&#; &#;&#; &#;&#;&#;. &#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;. To this end, Siheung City, located on the west coast of the Seoul metropolitan area, is behind Siheung and Banwol industrial complexes. As of , the number of air pollutant emission companies out of 7,300 tenants is about 2,000. In addition, some industrial lands are changed to residential lands, and complaints about odors are constantly occurring.
&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;, &#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;. In particular, after the residential area is formed next to the sewage treatment plant, pollutants generated from the sewage treatment plant move toward the residential area, and the severity of the damage caused by the odor is increasing.
&#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#; &#;&#;&#;&#;&#; &#;&#; &#;&#;. &#;&#; &#; 12&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;, &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;, &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#;, &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;. Therefore, the odor generated from the sewage treatment plant has been a big problem for the sewage treatment plant operators. Until December , cover was set for sedimentation and dehydration processes of sewage treatment plants, and washing towers and biofilters were installed as odor prevention facilities.
&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;. &#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;. &#;&#;&#;, &#; &#;&#;&#;&#;&#; &#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;, &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;. &#;&#;&#;, &#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;. &#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;. In the study, the starting point of the present invention, the characteristics of odor-causing compounds generated in each process of Siheung city sewage treatment plant were evaluated. At present, the sewage treatment plant in Siheung has established its own odor reduction plan. However, this reduction is simply covered by each process, the air in the cover is collected and treated in a odor prevention facility such as a biofilter. However, since the amount of air collected in each process is too large, a large blower and a biofilter are required at the rear stage. This in turn puts an economic burden on operators.
&#;&#;&#; &#;&#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;, &#;&#;&#; TRS &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;, &#;&#; &#;&#; &#;&#; &#;&#;, &#; &#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;.
Therefore, the characteristics of odor-causing compounds that occur in each process of sewage treatment plant are evaluated through instrumental analysis, and a real-time TRS monitoring system is installed to continuously measure and evaluate the odor occurrence trend of the process to identify operational problems and respond accordingly. The scheme, ie, the concept of the present invention, was derived.

Siheung Sewage Treatment Plant is equipped with the first stage treatment facility (gravity sedimentation method) for plant wastewater (115,000 m 3 / day) generated from Sihwa National Industrial Complex and domestic sewage (61,000 m 3 / day) generated throughout Sihwa City. Standard activated sludge process to remove organic matter in the process of decomposition and growth of aerobic microorganisms: 176,000 m 3 / day) and two-stage treatment facility (CNR (Cilium Nutrient Removal) process to remove nutrients such as nitrogen phosphorus): 103,000m 3 / day Is processed using). Also Siheung sewage treatment plants are treated with the food talriaek 50m 3 / day generated from pretreated 80 m 3 / day of food composting facility generated in sewage treatment plant site unlike a typical wastewater treatment plant.

TRS &#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;, &#;&#;&#;&#;&#;, &#;&#;&#; &#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; H2S, CH3SH,DMS. &#;&#;&#;&#;&#; &#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#;&#;. In terms of odor generation, each unit in the sewage treatment plant is a potential source of odor. Real-time TRS odor monitoring system was installed to monitor the tendency of sulfur compounds in sewage treatment plant. The reason for choosing TRS automatic measuring equipment is H 2 S, CH 3 SH, DMS in most organic waste related facilities such as sewage treatment plant, manure treatment plant and food treatment plant. This is because sulfur-based materials such as methyl disulfide have been identified as a cause of odor.

The TRS automatic measuring device (M102E, Eco-S & E, Korea) used SO 2 measuring device using UV fluorescence and thermally oxidized reducing sulfur compounds contained in the sample gas flowing into the measuring device. It is a device that converts to and measures it.
TRS &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#; &#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#;. &#;&#;&#;&#; &#;&#;&#;, 1&#; &#;&#;&#;, &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;, &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;. In particular, gas samples were taken from each unit process using TRS automatic measuring devices to measure complex odors and individual odor-causing substances in the laboratory. The sewage inlet, the primary sedimentation basin, and the rear stage of the bioreactor were sampled from the outside, and the rest of the processes were taken from the inside.
&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;, &#;&#;&#;&#; &#;&#;&#;, &#;&#;&#;, &#;&#;&#;&#;&#;, &#;&#;&#;, &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;, &#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;. &#;&#; &#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#;(H2S0.002ppm&#;&#;, CH3SH0.002ppm&#;&#;, ammonia 1ppm&#;&#;, acetaldehyde 0.05ppm&#;&#;)&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;. As a result of analyzing the odor concentration collected in each unit process, the concentration of factory wastewater inlet, mixing tank, food treatment, thickening tank, and dehydration tank was found to be higher than that of open clarifier and aeration tank. In addition, some of the individual odor items measured in several unit processes exceeded Korea's emission limit (H 2 S0.002ppm, CH 3 SH0.002ppm, ammonia 1ppm, acetaldehyde 0.05ppm).

In addition, if you look at the TRS concentration graph measured on the site boundary near the abandoned tank, it can be seen that the TRS concentration was high from 22:00 to 4:00 the next day. Odor generated in the aeration tank was continuously measured for more than 6 hours in the direction of the measuring sensor.
TRS &#;&#;&#;&#;&#; &#;&#; &#; &#;, &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#;. &#;, &#;&#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#; A2O process&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; methylation(-SH)&#;&#; aeration condition&#;&#; &#;&#;&#;&#;&#;&#; stripping&#;&#; &#;&#;&#;, &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;. In looking at the TRS measuring device, it was found that the effect on the concentration change of the odor gas was related to the operation of the aeration tank. In other words, the Siheung Sewage Treatment Plant operates the A2O process to remove nitrogen and phosphorus. In the anaerobic and anaerobic reactors, the odorous substances are methylated (-SH) and odorous substances are stripped under aeration conditions. It was found to occur a lot.
TRS &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#; &#;&#;&#;. &#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;(&#;&#;&#; &#;&#;&#;, &#;&#;&#; &#;&#;&#;&#; &#;)&#; &#;&#;&#; &#;&#; TRS &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#;. &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;, &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;, &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;.
By using the TRS analysis device, the odor of sulfur compounds generated in the sewage treatment process was monitored in real time, and the operation status of the sewage treatment process could be indirectly understood. As a result, the TRS odor concentration was sometimes high depending on the operation method of the sewage treatment plant process (when composting and sludge transportation process, etc.). Therefore, when the real-time continuous monitoring system is introduced into the sewage treatment plant, the operator checks the phenomenon of high odor concentration through the control system and establishes a quick countermeasure through immediate identification of the source of the odor so that the odor spreads around the sewage treatment plant. It was decided that the minimum could be prevented.

Sewage treatment facilities are reducing organic substances and nutrients present in sewage to a satisfactory level, but the odors generated from sewage and its treatment have not been removed to a satisfactory level. For this reason, sewage treatment plants are recognized as abominations by the residents.
&#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;, &#;&#;&#; &#;&#;&#;&#;&#; &#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;. &#;&#; &#; sulfides&#;&#; mercaptans&#; &#;&#; volatile reduced sulfur compounds(VRSCs)&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;. &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; hydrolysis&#;&#;&#;, &#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;. &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#;&#; 2&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#; (Koe, ; Sekyammah, K. , et al. , ). &#;&#; &#;&#;&#;&#; hydrogen sulfide, methyl mercaptan, dimethyl sulfide, carbon disulfide&#; carbonyl sulfide&#;&#; VSCs&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; (Camp Dresser & Mc Kee. , ). Odors associated with sewage treatment plants are mainly generated from mixtures of odorous substances such as volatile sulfur compounds, volatile nitrogen compounds and volatile fatty acids. Among these, volatile reduced sulfur compounds (VRSCs) such as sulfides and mercaptans are known as major odorous substances related to sewage treatment plants. This is because organic sulfur compounds are hydrolyzed under anaerobic conditions, or microorganisms or chemically reduced to release odorous substances from the wastewater. At this time, the odors emitted from settlements and solids treatment facilities are stronger or more severe, but the secondary aeration basins are mainly referred to in the literature as sources of odor from sewage treatment plants (Koe, ; Sekyammah, K., et al. , ). Aeration tanks have also been identified as major sources of VSCs such as hydrogen sulfide, methyl mercaptan, dimethyl sulfide, carbon disulfide and carbonyl sulfide (Camp Dresser & Mc Kee., ).
&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;, &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#; (Nurai Islam, A. et al. , ). 1&#; &#;&#;&#;&#; VSCs&#; 95% &#;&#;&#; 2&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#; (Hwang et al. , ). &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#;&#;, &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; (Camp Dresser & Mc Kee. , ). Sewage odors are generally not produced under aerobic conditions and may actually degrade (Nurai Islam, A. et al., ). More than 95% of the VSCs in the primary treated water are removed due to biodegradation and degassing in the secondary aeration process (Hwang et al., ). It is known that the rate of odor emission of the aeration tank is highest near the inlet or front end of the treatment process, and decreases inwardly toward the downstream end of the inflow into the sedimentation basin (Camp Dresser & Mc Kee., ).

In the meantime, there are studies on the quantification of malodors generated in sewage treatment plants and examples of researches on the concentration of malodors on site boundaries of sewage treatment plants. However, these studies are still at the level of monitoring research, such as the collection of atmospheric gases at one or two points on the site boundary of a treatment plant. On the other hand, foreign countries have been interested in generating and controlling VOCs and odorous gases for a long time and have conducted many studies. Kim. () have studied the correlation between the operating conditions and odorous compounds in sewage treatment plants and the establishment of odor reduction measures using them. Sekylamah et al. () found that the depth of the sludge blanket in the secondary settling basin affected the generation of odor in activated sludge tanks. That is, many sludges accumulate in the sedimentation basin to form anaerobic conditions and produce sulfur compounds under these conditions. Here they report that improving sludge sedimentation of secondary sedimentation cells and proper wasting of excess sludge can reduce the generation of sulfur compounds in bioreactors (Sekyammah, K., et al. ).
&#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#; head space &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;. &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;. &#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;. &#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#;&#; &#; &#;&#; (Schiffman, S. S. , et al. , ).
A common method of controlling the odor emitted from the activated sludge process is to cover the activated sludge process and collect and treat the gas in the head space. However, this method is expensive. Proper odor control in sewage treatment plants requires continuous monitoring of odors emitted from the treatment process and an understanding of the mechanisms of odor generation. Through this, each unit process of the sewage treatment plant can be adjusted to minimize the generation and release of odorous substances (Schiffman, SS, et al., ).

Bench-scale AAA and A / O (Anoxic-Oxic) activated sludge systems were fabricated and operated using an on-line TRS analyzer. Through this, the main odor gas emission sources from the bioreactors of sewage treatment plants were identified, and the odor emission mechanisms were revealed to suggest ways to reduce odor emissions.
&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; 1&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;. The sewage sample used was the first sedimentation tank effluent from the Seoul Jungrang sewage treatment plant near the laboratory.

A laboratory scale A / O activated sludge system was installed to experiment with the optimal control of the odor emitted from the bioreactor operation (Figure 6.6). The A / O activated sludge system was provided with one anoxic reactor having a capacity of 10 L and two aeration reactors each having a capacity of 10 L. Like the AAA activated sludge system below, the influent storage tank, the bioreactor, and the sedimentation tank were configured in the same way.

In addition, the lab scale scale AAA activated sludge system was installed to identify the odor tendency in the bioreactor. The AAA activated sludge system is a 4L bioreactor with a sedimentation tank at the rear end and a storage tank for influent at the front end. In the case of the bioreactor, the upper part was sealed with a cover, and a gas collecting device for TRS analysis and a gas collecting tube for instrument analysis were installed. The air injector of the bioreactor was operated at intervals of 2 hours for aeration and 2 hours for aeration without intermittent aeration. In addition, a stirring device was installed for smooth mixing between the inflow wastewater and the sludge inside the reactor. In the case of the inflow wastewater storage tank, a stirring device was installed to keep the characteristics of the wastewater constant, and a top of the storage tank was installed with a cover.

A laboratory-scale AAA activated sludge system was installed to evaluate total reducing sulfur compound emissions. From the real-time TRS measurement results, it was confirmed that the reducing sulfur compound accumulated in the anoxic state before the aeration phase was discharged by the degassing at the early stage of the aeration phase.

In addition, as can be seen in the graph comparing the TRS emission amount for the anaerobic phase and the aeration (aeration) phase with time in FIG. It was confirmed that a significant amount of odor could be removed when the gas was collected and treated.

Similar to the graph results of FIG. 1C in the AAA activated sludge system, the amount of odorous substances discharged from the first one-third of the aeration tank was 75.6% of the total amount of the odor emission. Therefore, it is believed that if the wastewater treatment plant is covered with about 30% of the aeration tank and the head space gas is collected and treated, it will be an economical and effective way to control the smell of the sewage treatment plant.

&#; 2 &#; &#; 3&#; &#;&#;&#; &#;&#; &#;&#;, &#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;(A)&#; &#;&#;&#;&#;&#;&#;&#;(10), &#;&#;&#;&#;&#;&#;(20), &#;&#;&#;&#;&#;(30), &#;&#;&#;(40), &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;(S1a,S1b,S1c,S2a,S2b)&#; &#;&#;&#;&#;.
As shown in Figures 2 and 3, the odor treatment means (A) introduced into the biological water treatment system according to the present invention is a chemical liquid cleaning processing unit 10, biofilter unit 20, adsorption treatment unit 30, the control unit ( 40) and various sensors S1a, S1b, S1c, S2a and S2b provided on the pipe.
&#;&#;, &#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;(A)&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;, &#;&#; &#; &#;&#;&#; &#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;,First, the odor treatment means (A) equipped with the odor active monitoring function introduced into the biological water treatment system according to the present invention effectively blocks the odor, collects and processes the odor, purifies with clean air, and then discharges it to the outside. As it aims to maintain a pleasant working environment, abide by the emission standards set by the Odor Prevention Act, and reduce civil odor complaints to public facilities,
&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;(A)&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;, &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;. The design of the malodor treatment means (A) with the malodor active monitoring function introduced into the biological water treatment system according to the present invention is to consider the treatment criteria, treatment method and efficiency so that the malodors to be treated in consideration of the characteristics of the malodor source. A sensor that can detect various odorous components is attached in place so that the operating conditions can be changed and adjusted according to the emission concentration.
&#;&#;&#;&#;&#;(P)&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;, &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;, &#;&#;&#;&#;, &#;&#;&#;&#;&#;, &#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#;&#; &#; &#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;, &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#;&#;. &#; &#;&#;&#;&#;&#;(P)&#; &#;&#; &#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;(continuos) &#;&#;&#;&#; &#;&#;&#; &#;&#;, &#;&#; &#;&#;&#;(&#;&#; &#;&#;&#;&#;) &#;&#; &#; &#;&#;&#;(batch) &#;&#;&#;&#; &#;&#;&#; &#;&#;, &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;(&#;&#; &#;&#;).In the organic waste treatment plant and bio power generation system, which are the source of odor, the odor spreading prevention device is additionally configured according to the odor characteristics peculiar to each facility such as import facilities, storage facilities, dehydration facilities, pretreatment facilities, anaerobic digestion facilities, and wastewater treatment facilities. For example, it is necessary to configure the collection device to realize local exhaust and then determine the final deodorizing capacity. This malodor generating source (P) is a continuous biological water treatment process, in particular aeration tank (or anoxic tank) or a batch biological water treatment process, especially in biological water treatment systems with concentrated selective malodor collection means according to the invention. It means the gas collected by the odor collecting means installed in the reactor (hereinafter referred to).
&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;. &#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;, &#;&#;&#;&#;, &#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#; &#;&#;.In addition, in order to select an appropriate treatment method in the composition of the odor treatment means, the prediction of the inflow concentration is most important. If the treatment target is set on the basis of this, a suitable treatment method can be selected in consideration of treatment efficiency, economic feasibility, site conditions, equipment cost and operating cost.
&#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;, &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;, &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#; &#;&#;&#;(TRS(Total Reduced Sulfur))&#; &#;&#; &#;&#;&#; 10-20pp &#;&#;&#;&#; &#; &#;&#; &#;&#;&#;&#;(A)&#; &#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;, &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;.
In view of the above, the present inventors consider that the main odor source of the odor generating source is generated from food waste, pretreatment of livestock manure, anaerobic digestion system, and total reducing sulfur compound (TRS) containing hydrogen sulfide as a main odor source. (Total Reduced Sulfur) has been found through a series of various field surveys and research procedures that it is appropriate to set the standard of treatment for this odor treatment means in anticipation of 10-20ppm concentration.
&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;, &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#;. Since the concentration of each source is predicted, the concentration conditions are summarized in the following table to select a rational treatment method.
&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;, &#;&#;, &#;&#;, &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;,In addition, since the most basic concept of deodorization treatment is the order of blocking, collecting, treating, and discharging, there are many shortcomings that focus only on the treatment method, so comprehensive concept setting and integrated control are important.
[&#;&#;]&#;[&#;&#;]&#;[&#;&#;]&#;[&#;&#;] &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;.
The basic concept of odor treatment is the process of [blocking] &#; [collection] &#; [treatment] &#; [discharge].
&#;&#;block
&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;. &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#; &#;&#;&#; &#;&#;&#; &#;&#;.
The surrounding area of odor generating source should be blocked to prevent unnecessary odor from entering and at the same time, it should have a function to prevent spreading to the outside. From this, the amount of odor generated should be minimized so that economic efficiency can be achieved.
&#;&#;Capture
&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#; &#;&#;&#;(Air Balance)&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;. &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;.The proper hood structure, installation location, and air balance should be taken to maintain the flow of air to accurately capture odors. Consideration should be given to the placement and collection of effective ducts to the treatment system.
&#;&#;process
&#;&#;&#; &#;&#;, &#;&#;, &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;, &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;. The odor characteristics, characteristics, and concentrations should be considered in consideration of treatment efficiency, economic feasibility, and land area.
&#;&#;exhaust
&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;
The final outlet should be designed in consideration of the effect on the surroundings and the proper height in consideration of the diffusion effect and the surrounding conditions.
&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;, &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;, &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;. &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#; 20&#; &#;&#;&#; &#;&#;&#;, &#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;(H2S)&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;.Next, the types of odors to be treated, especially the main types and concentrations of odorous substances generated in the treatment process of organic waste treatment plants, are generated at high concentrations of ammonia, as shown in the table below. Doing. There are about 20 kinds of odorous substances generated in the combined treatment of organic wastes, but the major substance is hydrogen sulfide (H 2 S), which is large in quantity and easy to control, and was used as a design control factor.
&#;) &#;&#; &#;&#;&#; D&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;.
Note) The above data is measured at D aerobic composting process.
&#;, &#;&#; &#;&#; &#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;, &#;&#;&#;&#;, &#;&#;&#;&#;&#;&#;&#; &#; &#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; 4&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;.In addition, four types of design odors were selected based on hydrogen sulfide, which is frequently generated in the manure treatment process and easy to detect and control, and added ammonia, acetaldehyde, and amines generated in the anaerobic treatment process. It was.
&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;.Furthermore, the concentration characteristics of odor generated during aerobic composting or anaerobic digestion of organic waste are as follows.
[&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;]
[Characteristics of Odor Substances in Anaerobic Digestion Treatment Plant]
(1) &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;.(1) The concentration of odor generated is high.
&#;&#;&#; &#;&#;&#;&#; &#;&#;, &#;&#;&#;&#;&#;&#; &#;&#; &#;&#; &#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;.Corruption or other reactions occur during the import and disposal of organic waste, causing severe odors in vegetables, meat and livestock manure within the organic waste.
(2) &#;&#; &#;&#;&#; &#; &#;&#;&#; &#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#;.(2) The main components of odor generation are hydrogen sulfide and ammonia.
&#;&#; &#;&#; &#;&#; &#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#; &#;(S) &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;. &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;.High emulsified hydrogen and ammonia concentrations are generated, which is generated by sulfur (S) -based organic matter in the manure as hydrogen emulsion and by the anaerobic nitrogen-based components in the food as ammonia. However, sulfide-based components tend to show low reaction with nitrogen-based components during development.
(3) &#;&#;&#; &#;&#;, &#;&#; &#;&#;&#;&#; &#;&#;.(3) There is much moisture, and there is much dust generation amount.
&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;, &#;&#;&#; &#;&#;&#;&#; &#;&#;, &#;&#;, &#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;.Due to the characteristics of organic wastes containing a large amount of moisture and the moisture generated during fermentation, high humidity conditions are created.Many dusts are introduced along with the process of mixing, crushing and drying organic wastes. A significant amount will be introduced.
(4) &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;.(4) Preventive measures to prevent clogging in the facility due to high odor are necessary.
&#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;. &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;.Due to excessive growth of microorganisms, excessive coating of carriers and clogging of carrier pores inhibits the growth of microorganisms and lowers the treatment efficiency, making it difficult to maintain long-term and efficient operation. Therefore, selecting the deodorization method having both stable treatment and economical efficiency by preparing the appropriate countermeasures by grasping the above characteristics is an important problem.
(5) &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;.(5) It is difficult to block odor at treatment facility.
&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;. &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;.
It is very difficult to block the odor generated in each treatment process through the import process, the treatment process and the fermentation process in the treatment process to prevent it from being discharged to the outside. To this end, it is necessary to prevent a sufficient sealing device and blocking structure.
&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;(&#;&#;&#;&#;&#;)&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;>Characteristics of Odor Substances Generated from Combined Organic Waste Treatment (Aerobic Digestion)>
&#;, &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#;, &#; &#;&#;&#; &#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#; 11&#; &#;&#;&#;&#;&#;. '&#;&#;&#;&#;'&#; &#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;.In addition, the correlation between the total reducing sulfur compound concentration and the compound odor was measured in the following manner, and a graph showing the relationship between the odor index calculated by each sewage treatment plant and the compound odor was attached to FIG. 11. 'Composite odor' refers to a smell that gives off a sense of displeasure and disgust by stimulating a human's sense of smell when two or more odorous substances are present in combination.
(1) &#;&#;&#;&#; &#;&#;&#; 6&#;&#; &#;&#;&#;&#;&#;&#;&#; &#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;.(1) The purpose of this study was to evaluate the feasibility of this sewage treatment plant odor investigation through the correlation analysis between each compound and the mixed odor in six sewage treatment plants.
(2) &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#;(&#;&#; &#; &#;&#;)&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;.
(2) For this purpose, the individual odor index for each compound detected by each sewage treatment plant (see below) was calculated and geometrically averaged to calculate the integrated odor index at each point.
(3) &#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;. (3) The correlation between the malodor index calculated for each sewage treatment plant point and the complex malodor for each point was evaluated.
(4) &#;&#; &#;&#;, &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;. &#;&#; &#;&#;&#; &#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;.(4) As a result of the evaluation, it was confirmed that as the malodor index increased, the concentration of the complex malodor increased. This confirms that the survey analysis method was properly performed.
(5) &#;&#; &#; 10&#;&#;, &#; &#;&#; &#;&#;&#; 6&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;.(5) Also in FIG. 10, the analysis results confirmed that the compounds contributing to the malodor at six sewage treatment plant points were sulfur compounds.
(6) &#;&#;, &#; 10&#;&#;, &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#; &#;&#;, &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#;, &#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;. (6) However, in FIG. 10, in the NPC and Nanji Sewage Treatment Plant, despite the low odor index, a relatively high compound odor was detected, which is a contribution of a compound other than the compound covered by the process test method. Judged.
(7) &#;&#; odor index&#; &#;&#;&#; &#;&#;&#; &#;&#; &#; 10&#;&#;, &#;&#;&#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#;&#; odor index &#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;.
(7) Looking at the results shown in the above odor index In Figure 10, the odor index and composite odor is detected in the Siheung sewage treatment plant and Seonam sewage treatment plant low.
&#;&#;&#;&#; &#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;.
Next, since the odor generated from the odor generating source is effectively collected and the discharge path is set, the main points of collection and discharge are as follows.
&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;
Focus on Odor Collection Emissions Design
(1) &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;.(1) Designed to meet the odor emission characteristics of odor generating sources.
(2) &#;&#; &#; &#;&#;&#; &#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;.(2) The hood and direct connection are to be intended to induce airflow in the odorous discharge space, not just suction.
(3) &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;.(3) Collected odors should be collected in a uniform manner in a balanced manner so that they do not accumulate in some sections.
(4) &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;, &#;&#; &#; &#;&#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;.(4) The route of collecting duct is to be set efficiently to take into consideration the interruption of flow, stop and interference with peripheral devices.
(5) &#; &#;&#; &#;&#;&#;&#; Air Balance&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;(Test Hole)&#; &#;&#;&#;&#;&#; &#;&#;.
(5) Each hood terminal is to be provided with air volume control sound wave and test hole for setting Air Balance.
&#;&#;, &#;&#;&#; &#;&#;&#;&#;&#; &#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#; &#;&#; &#;&#;&#;&#;. &#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;.On the other hand, the method of discharging the odor after the proper treatment is also a part that can not be neglected. In the present invention, it was designed as follows.
(1) &#;&#;&#; &#;&#; &#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;, &#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;.(1) After the treatment of odor, the discharge was immediately discharged from the rear stage of the biofilter. If the performance was insufficient due to the growth of the initial microorganisms of the biofilter, it was finally discharged through the activated carbon adsorption unit of the rear stage.
(2) &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;, &#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;, &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#; &#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;.(2) The final outlet should be designed to be as high as possible on the ground, but the surrounding conditions should be taken into consideration so that people do not come in direct contact with each other and maintain the height to prevent vortex and trickle phenomena caused by nearby buildings or structures. .
(3) &#;&#;&#; &#;&#; &#;&#; &#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#; &#;&#; &#;&#;&#; &#;&#;&#;&#;, &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;.(3) At the rear end of the bio filter and the final discharge port, sensors for detecting hydrogen sulfide were attached and odor analysis was conducted to ensure odor reduction.
(4) &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;.(4) The final outlet structure was eccentrically connected to the duct so that the final outlet concentration could be smoothly mixed in the outlet, taking into account the average concentration of the final outlet.
(5) &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;.(5) In order to firmly support wind and self-weight in consideration of the diameter and height of the outlet, a floor foundation shall be installed and fixed.
(6) &#;&#;&#; &#;&#;&#; SS400 &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;, &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;.
(6) The outlet body is made of SS400, so that the inside is corrosion-resistant to prevent corrosion, and the outside is finished with anticorrosive coating.
&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;. &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; (1) &#;&#;&#;&#;&#;, (2) &#;&#;&#;&#;, (3) &#;&#;&#;&#;&#; &#;&#;, (4) &#;&#;&#;&#; &#;&#;&#;&#;, &#;&#; &#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#; &#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;.
Before proceeding with the treatment of odor based on such a design, it is necessary to collect odor generated in the anaerobic digestion process of an organic waste treatment plant or a livestock manure treatment facility by process and transport it by using a blower and a duct pipe. The main odor generating processes in organic waste treatment plants or livestock manure treatment facilities are (1) pretreatment, (2) dehydration, (3) anaerobic digestion, and (4) wastewater treatment. It is advisable to determine the design of anaerobic digestion and wastewater treatment facilities first.
&#;&#;&#;&#;&#;&#;&#;(10), &#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#; 5&#; &#; 2 &#; &#; 3&#;&#;, &#;&#; &#;&#;&#;&#;&#;(10)&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;, &#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;. &#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;. &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;. In FIGS. 5, 2 and 3, which are schematic views of the chemical liquid cleaning processing unit 10, in particular, the chemical liquid cleaning tower, the chemical liquid cleaning processing unit 10 is suitable for treating water-soluble odorous substances, inexpensive installation cost, and dust treatment. Has In addition, the efficiency of chemical cleaning is determined by the replacement cycle of purified water. However, there is a disadvantage in that the treatment water cost is generated and the water-insoluble odor treatment is difficult.

And a pressure gauge (circular 'P' in FIG. 5, the same in other drawings hereinafter) are introduced into the filling body, ie, sprayed or sprayed through the injection nozzle 13 through the injection nozzle 13. The chemical liquid is replenished in the chemical tank 15 as needed, and water is supplied from the water supply unit 17 to ensure an appropriate chemical liquid concentration and flow rate. Air containing the odor is sucked through the intake portion (A1) and passes through the median layer (11) and finally discharged by the suction force of the blower to go through the next process.
&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#;. &#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; 5~20mm &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#;, &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;, &#;&#;(&#;&#; &#;&#;&#;)&#; &#;&#;(&#;&#; &#;&#;)&#;&#; &#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;, &#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#;&#; &#;&#;&#; &#; 0.92-0.96g/&#;&#;&#; &#;&#;&#;&#;(&#;: &#;&#;&#;&#;&#;)&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#;.The media may be a variety of members, but basically it is desirable to improve gas-liquid contact. For example, the media may be a product obtained by cutting an extruded synthetic resin tube into a length of 5 to 20 mm, and the media may include a perforated plate having a plurality of holes formed therein to prevent the loss of the media at the top and bottom of the media layer. In the introduced state, when spraying (or spraying) the chemical liquid (or washing water), the chemical liquid is filled to some extent between the upper and lower perforated plates, and the media has a density of about 0.92-0.96 g / cm 3 so that the media can flow by water flow. And made of a material of synthetic resin (eg polyethylene).
&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;, &#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#;.In addition, it is preferable that the cutting tube-type media to enhance gas-liquid contact has a plurality of external protrusions for buffering and collision between media and the internal protrusions for increasing the surface area.

&#;&#;&#;&#;(11)&#; &#;&#;&#;&#;(13)&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; 1&#; &#;&#;&#; &#;&#; 2&#; &#;&#; &#;&#;&#; &#; &#;&#;.The media layer 11 and the spray nozzles 13 may be configured as two or more layers instead of the one-layer structure shown as needed.
&#;&#;, &#;&#;&#;, &#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;(&#;&#;&#;)&#; &#;&#; &#;&#;, &#;&#;&#; 2&#; &#;&#; &#;&#; &#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#; &#; &#;&#; &#;&#;&#;&#;, &#; &#;&#;&#;(&#;&#;&#;)&#; &#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#; &#; &#;&#;&#; &#;&#; &#;&#; &#;&#;&#;&#;&#;.On the other hand, media, especially cut-tube media, have foreign substances (scales) stuck on the inside and outside surfaces with time of use, and this may cause secondary contamination or a decrease in the age of chemical liquids. Therefore, it is desirable to reduce the operating cost by increasing the chemical replacement cycle and to maintain the cleaning treatment efficiency at a constant level.

The regenerative stirring means 19 is installed between the upper and lower perforated plates of the media layer to stir the media. The rotary shaft 19A is connected to the motor 19C directly or via a speed reducer, and a plurality of protrusions are coupled to the outer peripheral surface of the rotation shaft. It consists of a stirring blade 19B.

The inner tube 19b may take a method of separating and discarding the inner tube and inserting a new inner tube when the drainage hole h2 is blocked using a cheap synthetic resin hose. If necessary, the inner tube may be non-circular (polygonal, elliptical, etc.) or not at least inner tube of cross section in order to ensure mutual coincidence of the drainage holes (h2) (h1) of the inner and outer tubes (19b) and (19a). The outer surface has a longitudinal concave-convex shape, and at least the inner surface of the outer tube may have a shape corresponding to the outer circumferential surface shape of the inner tube so that the coupling between the drain holes h2 and h1 can be easily performed.

The biofilter unit 20 has a low maintenance cost and shows very high processing efficiency for some materials. However, there are disadvantages in that the installation area is large and the biological treatment of the material is difficult.
&#;&#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#; &#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#; &#; &#;&#; &#;&#;&#; &#;&#;&#;(23)&#; &#;&#;&#;&#;, &#;&#;&#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;&#;. The core technology of the biofilter consists of a media filling unit 23 which can absorb microorganisms capable of decomposing odors and odorous substances and maintain the function of microorganisms by providing a living space of microorganisms. Decomposition of odorous substances is removed by the following series of processes.
(1) &#;&#;&#;&#;&#; &#;&#;&#;&#;&#;&#; &#;&#;&#; &#;&#;&#;&#;&#; &#;&#;&#;&#;(25B)&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#; &#;&#;&#;&#;(21p)&#; &#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#;&#;&#;&#;(21)&#; &#;&#;&#;. &#;&#; &#;&#; &#;&#;&#;&#;(25A)&#;&#; &#;&#;&#;&#; &#;&#;&#;&#; &#;&#; &#;&#;&#;&#; &#;&#;, &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#; &#;&#;&#;(23)&#; &#;&#;&#;&#; &#;&#;.(1) Water in the lower part of the housing supplemented by the water supply unit 25B with the pollutant gas containing the malodorous substance and the organic compound is pumped by the circulation pump 21p and passed through the humidity controller 21 sprayed from the upper nozzle. Thereafter, the water is supplied from the water supply unit 25A to pass through the media filling unit 23, which is the core of the biofilter, in which water is sprayed from the nozzle.

Total reducing sulfur compound sensor is a device that thermally oxidizes reducing sulfur compound contained in incoming sample gas, converts it into sulfur dioxide, and measures it. Sulfur dioxide is excited when it encounters ultraviolet (UV) light (SO2 *), and the concentration of sulfur dioxide in the sample gas is measured by the intensity of light generated here. Calibrate the meter using H2S standard gas. The measurement is used with PMT, dark offset, UV lamp ratio, residual light, and sample gas temperature and pressure to calculate final concentration. The calculated concentration values are stored in the instrument's internal data storage system (iDAS Section) and displayed to the user as analog signal outputs and various digital signals and meter screens.
