기존 생물학적 처리를 위한 무산소 관련 공법은, A2O 공법 등 혐기-호기 생물학적 반복 공정에서 호기성 미생물에 의해 생성된 질산(NO2) 등이 혐기 공정에서 탈질균에 의해 질산 성분 중 산소를 취하고 질소를 버려, 질소만 N2 가스화하여 대기중으로 날아가는 공법이다.In the existing anaerobic-related methods for the biological treatment, nitric acid (NO2) produced by aerobic microorganisms in anaerobic-aerobic biological repetition processes such as A2O method, takes oxygen out of nitrate components by denitrification in anaerobic processes, and discards nitrogen, Only N2 gasification and flying to the atmosphere.

이는 혐기-호기 또는 혐기-호기-혐기-호기 등 성상이 다른 미생물을 반복적으로 구성하여 폐수 중 질소를 집중적으로 제거하는 공법으로 시중에 많이 적용중인 공개된 기술이다.This is a publicly known technique that is widely applied as a method of intensively removing nitrogen from wastewater by repeatedly forming different microorganisms such as anaerobic-aerobic or anaerobic-aerobic-anaerobic-aerobic.

그러나 상기한 무산소 공정을 위한 시설을 설치시, 탱크를 제작할 때, 그 탱크 위를 슬라브로 마감하고 맨홀을 밀폐하는 방식으로 시공하고 있다. 이러한 구조에서는 “가축분뇨처리시설 설계지침“ 등에서 혐기 공정의 밀폐시 매탄 가스에 의한 폭발 위험 등으로 공조용 벤트 등을 설치함으로 인해, 사실상 탈질균의 산소와의 접촉으로 인해 그 질소제거 효과가 떨어지는 실정이다.
However, when the facility for the anoxic process is installed, when the tank is manufactured, it is constructed by closing the slab on the tank and sealing the manhole. In such a structure, air conditioning vents, etc. are installed due to the risk of explosion due to methane gas when the anaerobic process is closed in the “design guidelines for livestock waste treatment facilities”, and thus the nitrogen removal effect is inferior due to the contact of the denitrification bacteria with oxygen. It is true.

이에 본 발명은 무산소 조인 탱크(3)의 수표면에 부유식 차단막을 표면에 설치하여 탈질균의 산소와의 접촉이 최소화되도록 한다. 그러나 비록 차단막을 설치하여도 차단막이 전개되지 못하는 일부 폐수면을 통하여는 발생되는 매탄가스가 자연스럽게 배출되도록 하였다.Accordingly, the present invention is installed on the surface of the floating barrier membrane on the water surface of the oxygen-free joining tank 3 to minimize the contact of the denitrification bacteria with oxygen. However, even though a barrier was installed, the methane gas generated was naturally discharged through some of the waste water surface where the barrier could not be developed.

또한 탈질균의 특징상 수온이 떨어지면 탈질 활동이 급격히 떨어지는바, 부유식 차단막의 하부에 온수를 보유하도록 하고, 지상의 히팅 탱크에서 순환펌프를 통해 차단막에 온수를 공급 및 회수하는 보일러 원리의 온수 주머니를 설치하여 적정온도를 유지하여 탈질균의 처리 효과를 극대화하도록 하였다
In addition, the denitrification activity drops rapidly when the water temperature drops due to the characteristics of the denitrifying bacteria, so that hot water is kept in the lower portion of the floating barrier membrane, and the hot water bag of the boiler principle of supplying and recovering hot water to the barrier membrane through a circulation pump in the ground heating tank. Was installed to maintain the proper temperature to maximize the treatment effect of denitrification bacteria

본 발명의 주요 구성은, 질소 성분을 포함하는 폐수를 수용하는 무산소 조인 탱크(3)의 폐수 상면에, 부유물질을 포함하는 단위부유체(50)가 상호 연결된 형상의 차단막(1)이 부유하도록 설치한 것을 특징으로 하며, 상기 차단막(1)은 내부에 주머니 형상의 수용공간(30)을 갖는 연결부재(10)와, 연결부재(10)의 수용공간(30) 내부에 수용되는 부유체와, 부유체 저면에 설치하는 온수자켓(15)을 포함하는 것을 특징으로 하며, 상기 부유체는 스치로폴(2)인 것을 특징으로 하며, 상기 온수자켓(15)에의 온수는, 히팅탱크(11)에서 가열된 물을 순환펌프(12)에 의하여 온수호스(32)를 통하여 공급 및 순환되게 구성한 것을 특징으로 하며, 상기 단위부유체(50)는 연결수단(31)으로 상호 연결되며, 상기 부유체(50)에 내장되는 온수자켓(15) 끼리는 온수호스(32)로 연결되는 것을 특징으로 한다

본 발명은 고농도 질소성분 폐수나 축산폐수의 질소 성분을 제거하기 위한 질산 처리시설에서, 기존 생물학적 처리시설의 폭기조나 무산소조의 질산 처리시설에서 무산소화를 통하여 질산화 처리를 촉진할 수 있다. 즉, 본 발명에 의하면, 무산소 조인 탱크(3)의 폐수 표면에 부유식 차단막을 표면에 설치하여 탈질균의 산소와의 접촉이 최소화되도록 한다.The present invention can promote nitrification in an nitric acid treatment facility for removing nitrogen components of a high concentration nitrogenous wastewater or livestock wastewater, by anoxicizing in an aeration tank of an existing biological treatment facility or an nitric acid treatment facility of an anoxic tank. That is, according to the present invention, the floating barrier film is installed on the surface of the wastewater of the oxygen-free joining tank 3 to minimize the contact of the denitrifying bacteria with oxygen.

또한 본 발명에 의하면, 온수자켓에 의한 탱크 내의 보온이 가능하여 탈질을 위한 탈질균의 배양에 최적의 온도조건을 제공하여, 탈질균의 효율적인 증식으로 폐수 내의 질소 성분의 제거에 매우 효과적이다.In addition, according to the present invention, it is possible to insulate in the tank by the hot water jacket to provide the optimum temperature conditions for the cultivation of denitrification bacteria for denitrification, and is very effective in the removal of nitrogen components in the waste water by efficient propagation of denitrification bacteria.

즉, 탈질균의 특징상 수온이 떨어지면 탈질 활동이 급격히 떨어지는바, 부유식 차단막의 하부에 온수를 보유하도록 하고, 지상의 히팅 탱크에서 순환펌프를 통해 차단막에 온수를 공급 및 회수하는 보일러 원리의 온수 주머니를 설치하여 적정온도를 유지하여 탈질균의 처리 효과를 극대화하도록 하였다
That is, the denitrification activity drops sharply when the water temperature drops due to the characteristics of the denitrifying bacteria, so that hot water is kept at the bottom of the floating barrier membrane, and the hot water of the boiler principle of supplying and recovering hot water to the barrier membrane through a circulation pump in the ground heating tank. The bag was installed to maintain the proper temperature to maximize the treatment effect of denitrification bacteria.

By providing the floating barrier membrane (1) in this way to minimize contact with the oxygen of the denitrification bacteria, the generated methane gas is to be discharged through some holes of the barrier membrane.

또한 탈질균의 특징상 수온이 떨어지면 탈질 활동이 급격히 떨어지는바, 부유식 차단막(1)의 하부에 온수를 보유하도록 온수자켓(15)을 내장시켜 탈질 활동이 떨어지지 않토록 하였다In addition, the denitrification activity drops sharply when the water temperature drops due to the characteristics of the denitrifying bacteria, so that the denitrification activity does not fall by embedding the hot water jacket 15 to hold hot water in the lower portion of the floating barrier membrane 1.

그리고 지상의 히팅 탱크(11)에서는 순환펌프(12)를 통해 차단막(1)에 내장된 온수를 공급 및 회수하도록 하였다. 히팅탱크(11)는 가열체(18)가 구성되어 내부 온수가 가열되게 구성되며 필요에 따라서는 온수 온도를 조절 가능하도록 하거나 또는 자동 온도 설정으로 일정한 온도로 항상 적정온도를 유지토록 하여 탈질균 처리 효과를 극대화할 수 있다
