Description

악취가스를 바이오 필터방식으로 탈취하는 장치{apparatus for deodorizing fetor gas in the biofilter way}Apparatus for deodorizing fetor gas in the biofilter way

본 발명은 악취가스를 바이오 필터방식으로 탈취하는 장치에 관한 것으로, 좀더 상세하게는 악취가스 중의 악취성분을 폴리우레탄 폼을 이용하여 전처리한 후 미생물을 이용하여 제거하는 바이오 필터식 탈취장치에 관한 것이다.The present invention relates to an apparatus for deodorizing malodorous gas by a biofilter method, and more particularly, to a biofilter type deodorizing apparatus for removing malodorous components in a malodorous gas by using microorganisms after pretreatment using a polyurethane foam. .

하수처리장, 양돈장, 축산 폐수처리장, 도살장, 식품공장, 각종 화학공장 등에서 발생하는 악취성분은 발생물질이나 발생원에 따라 오염물질의 구성이 매우 다양하며, 주요 악취 유발 물질로는 황화수소, 메르캅탄과 같은 황화합물, 암모니아, 아민과 같은 질소화합물, 벤젠, 톨루엔, 에틸벤젠, 크실렌 등을 포함하는 휘발성 유기화합물(Volatile Organic Compounds : VOCs) 또는 휘발성 황화합물(Volatile Sulfur Compounds) 등이 있다.Odors that occur in sewage treatment plants, pig farms, livestock wastewater treatment plants, slaughterhouses, food plants, and various chemical plants vary greatly in the composition of pollutants depending on the source or source of occurrence.The main odor causing substances include hydrogen sulfide and mercaptan. Volatile Organic Compounds (VOCs) or Volatile Sulfur Compounds, including sulfur compounds, nitrogen compounds such as ammonia and amines, benzene, toluene, ethylbenzene, xylene, and the like.

상기와 같은 악취성분들은 주로 물과 이산화탄소(CO2)로 전환되어 제거되는 것이 일반적이며, 무기 및 유기 악취를 탈취하기 위한 방법으로는 크게 물리ㆍ화학적인 탈취와 생물학적 탈취로 구분되고, 주로 활성탄 흡착 또는 약품 세정 등 물리ㆍ화학적 탈취기술이 사용되었으나, 여기에는 약품, 재료비 등 운영비의 문제들이 상존해 왔다.Such odor components are generally converted to water and carbon dioxide (CO 2 ) and are generally removed. Methods for deodorizing inorganic and organic odors are classified into physical and chemical deodorization and biological deodorization. In addition, physical and chemical deodorization techniques such as chemical cleaning have been used, but problems of operating costs such as chemical and material costs have existed.

상기 생물학적 탈취방법은 토양 미생물을 이용하는 토양 탈취법, 폭기조 내의 활성슬러지를 이용하여 악취물질을 제거하는 폭기조 탈취법 등이 있으나, 많은 부지면적을 필요로 하고 압력손실이 높아 동력비가 많이 소요되는 단점이 있다.The biological deodorization method is a soil deodorization method using soil microorganisms, aeration tank deodorization method to remove odorous substances by using activated sludge in the aeration tank, etc., but requires a lot of land area and high pressure loss high power costs are disadvantages have.

상기 생물학적 탈취방법 중 최근에는 작은 공간에서 적은 비용으로 운영할 수 있으며 탈취효율이 높은 미생물 담체를 이용하는 충전형 미생물 탈취법에 대한 관심이 높아지고 있다.Recently, among the biological deodorizing methods, there is a growing interest in the filling type microorganism deodorizing method using a microorganism carrier which can be operated at a low cost in a small space and has a high deodorizing efficiency.

담체 충전형 미생물 탈취방법은 미생물을 고정화시킨 담체로 채워진 충전탑에 악취가스를 유입시켜 제거하는 방법으로서, 충전탑 속의 미생물은 악취가스의 분해로 발생되는 에너지와 소량의 영양분에 의해 생장이 유지된다. 즉 배양되는 미생물에 의하여 악취성분들이 분해되어 제거되는 것이다.Carrier-filled microorganism deodorization method is a method of introducing and removing malodorous gas into a packed column filled with a carrier to which microorganisms are immobilized, and microorganisms in a packed column are maintained by energy and a small amount of nutrients generated by decomposition of malodorous gas. . That is, odor components are decomposed and removed by the cultured microorganisms.

상기와 같은 미생물을 이용한 생물학적인 방법은 지금까지 주로 일반 오ㆍ폐수 처리에 이용되고 있으나, 최근에는 악취제거 분야에도 적용되어 그 활용성이 증대되고 있다.Biological methods using the microorganisms as described above have been mainly used for general wastewater and wastewater treatment, but in recent years has been applied to the field of odor removal has increased its utility.

이러한 대기분야에서의 처리기술들은 미생물을 고농도로 담체에 고정화하여 안정적으로 배양하고 생장할 수 있도록 하는데 중점을 두고 있으며, 이러한 미생물은 성장 및 증식을 위하여 수분 및 영양소를 요구하고, 특히 대부분의 생물학적 악 취 탈취장치의 경우 적절한 수소이온지수(pH) 환경조건을 유지하는 것이 중요하다.These technologies in the air are focused on the stable growth and growth of microorganisms by immobilizing the microorganisms on carriers, and these microorganisms require moisture and nutrients for growth and proliferation. In the case of odor deodorizers, it is important to maintain appropriate pH (pH) environmental conditions.

갑작스런 pH의 변화는 미생물의 악취성분 분해효율을 저하시키고, 지속적으로 pH의 변화를 가속시킴으로써 탈취장치의 성능을 저하시키는 악순환을 초래한다.Sudden change in pH results in a vicious cycle of degrading the odor component degradation efficiency of microorganisms, and continuously decelerating the performance of the deodorizer by accelerating the change in pH.

특히 황계 악취성분인 황화수소(H2S)가 30ppm 이상인 경우는 물과 반응하여 황산(H2SO4)이 생성되며, 50ppm 이상의 고농도 황화수소가 유입되면 미생물이 고정ㆍ생육하고 있는 담체 통과시 높은 산성도에 의하여 담체의 미생물이 폐사하여 미생물을 재접종시키기 전까지는 탈취기능이 중단되는 문제가 발생한다.In particular, when sulfur sulfide (H 2 S), which is a sulfur-based odor component, is 30 ppm or more, sulfuric acid (H 2 SO 4 ) is produced by reaction with water. This causes a problem that the deodorizing function is stopped until the microorganisms of the carrier are dead to reinoculate the microorganisms.

따라서 생물학적 탈취방법으로 악취성분을 제거하기 위하여는 미생물의 생육 환경조건을 최적의 상태로 유지하는 것이 매우 중요하며, 미생물 탈취장치의 운전조건인 온도, 습도, pH 및 영양분 공급을 정밀하게 조정할 수 있는 정밀운전 시스템의 개발이 요구된다.Therefore, it is very important to keep the growth environment conditions of microorganisms in optimum condition in order to remove odor components by biological deodorization method, and it is possible to precisely adjust temperature, humidity, pH and nutrient supply which are operating conditions of microorganism deodorizer. Development of precision operation system is required.

본 발명이 해결하고자 하는 과제는 악취가스의 생물학적 탈취장치에 있어서 악취성분을 분해하는 미생물이 최적의 환경조건하에서 악취성분을 분해할 수 있도록 운전조건을 최적화한 탈취장치를 제공하는 데 있다.The problem to be solved by the present invention is to provide a deodorizing device in which the operating conditions are optimized so that the microorganisms decomposing odor components in the biological deodorizing device of odor gas can decompose odor components under optimum environmental conditions.

이때, 황(sulfur)계 악취 성분인 황화수소의 농도가 높을 경우, 상기 황화수소는 상기 담체층(141)을 통과하는 동안 물과 반응하여 황산을 생성하므로 담체층(141)의 하부로 내려갈수록 황산의 농도가 증가하게 됨과 더불어, 상기 생성된 황산은 중력에 의해 하부로 흘러내려 감에 따라 상기 담체층(141)의 하부는 황산의 농도가 증가하게 되어 미생물이 생존할 수 없는 환경이 된다.At this time, when the concentration of hydrogen sulfide which is a sulfur-based odor component is high, the hydrogen sulfide reacts with water to generate sulfuric acid while passing through the carrier layer 141, so that the sulfur sulfide is lowered to the lower portion of the carrier layer 141. In addition to increasing the concentration, as the produced sulfuric acid flows downward by gravity, the lower portion of the carrier layer 141 increases the concentration of sulfuric acid, so that the microorganisms cannot survive.

상기 황산을 중화시키기 위하여 2차 처리수 저장탱크(150)의 2차 처리수에 약품투입장치를 통하여 알카리성 약품을 투입하여 악취가스와 함께 상기 담체층(141)을 하향 통과시키게 되나, 상기 담체층(141)의 상부는 알카리성인 2차 처리수에 의하여 알카리성이 강하고, 상기 담체층(141)의 하부는 산성인 황산에 의하여 산성이 강하게 되므로 상기 담체층(141)의 수소이온지수는 상하 간에 불균일하게 된다.In order to neutralize the sulfuric acid, alkaline chemicals are introduced into the secondary treated water of the secondary treated water storage tank 150 through the chemical injection device to pass the carrier layer 141 downward along with the odor gas, but the carrier layer The upper portion of the carrier 141 is alkaline due to alkaline secondary treated water, and the lower part of the carrier layer 141 is acidified by acidic sulfuric acid, so that the hydrogen ion index of the carrier layer 141 is nonuniform between the upper and lower sides. Done.

미생물은 적절한 온도, 습도, 수소이온지수 및 영양분이 공급되어야 활성이 증가되어 악취가스를 효율적으로 분해할 수 있는데, 상기 담체층(141)의 상부와 하부에서는 미생물의 수소이온지수 환경이 적정범위를 벗어나게 되어 악취가스 분해효율이 저하되고 탈취기(100)의 성능을 떨어뜨리게 되므로 이를 방지하기 위한 적절한 운전방법의 개선이 요구된다.The microorganisms must be supplied with appropriate temperature, humidity, hydrogen ion index and nutrients to increase their activity to efficiently decompose malodorous gases. Deterioration of the odor gas decomposition efficiency is lowered and the performance of the deodorizer 100 is deteriorated, so an improvement of an appropriate operation method for preventing this is required.

The pH of the upper portion of the carrier layer 141 may be increased by combining any one or two or more methods such as increasing.

또한, 상기 담체층(141) 하부의 pH가 높을 경우에는, 탈취팬(110)을 통하여 인입되는 악취가스의 유량증가 및/또는 2차 처리수 분사기(143)의 분사량 감소 등의 방법으로 상기 담체층(141) 하부의 pH를 낮출 수 있다.In addition, when the pH of the lower portion of the carrier layer 141 is high, the carrier may be increased by increasing the flow rate of the malodorous gas introduced through the deodorizing fan 110 and / or reducing the injection amount of the secondary treated water injector 143. The pH under the layer 141 can be lowered.
