Abstract

본 발명은 고농도 유기폐수나 난분해성 산업폐수등을 처리하기 위하여 제올라이트 X를 충진한 2배드(Bed) 산소 PSA를 사용하여 산소 농도 90－93%, 압력 0.7－1Kg/㎠로 농축산소를 제조하여 밀폐식 다단 활성슬리지반응기에 공급하여 활성슬리지용 8－15g/ℓ의 고농도로 유지시키는 데에 충분한 용존산소를 공급하며 반응된 고농도 활성슬리지는 관형 한외여과막을 사용하여 순환 선속도를 1－3m/s로 유지하여 가급적 분리막의 오염을 줄이고 투명한 투과수를 얻음으로써 고농도 오염폐수, 난분해성 폐수 등을 효율적으로 처리할 수 있는 폐수처리 방법에 관한 것이다.
