- 협잡물제거장치(1), 제사장치(2), 저류조(3) 및 미세기포부상장치(4)를 포함하여 상기 미세기포부상장치(4)에 의해 부유성투사류 및 콜로이드성부유물질까지 제거하게 되는 전처리단계; 생물반응조(5) 및 미세기포부상장치(6)를 포함하여 상기 미세기포부상장치(6)에 의해 생물반응조에서 고농도의 MLSS 농도유지를 가능케하는 생물처리단계; 오존발생장치(7)를 구비한 오존접촉조(8) 및 미세기포부상장치(9)를 포함하여 상기 오존발생장치(7) 및 오존접촉조(8)에 의해 철염계통의 화학적 응집제 대신 강한 산화력을 가진 오존으로 처리하게 되어 잔존 BOD는 물론 COD, 탈색, 멸균까지 하게 되는 후처리단계로 정화되는 것을 특징으로 하는 유기성폐수의 정화방법.
- 제1항에 있어서, 생물처리단계에는 슬럿지저장조(10), 응집조(11), 탈수기(12)를 포함하여 후단계의 미세기포부상장치(6)(9)로부터 얻어지는 슬럿지를 탈수시키는 물리화학처리단계를 추가로 포함시키는 것을 특징으로 하는 유기성폐수의 정화방법.
- 제1항에 있어서, 각 단계에 설치되는 미세기포부상장치(4)(6)(9)는 기포경이 5-50미크론의 초미세기포를 발생시키는 것을 특징으로 하는 유기성폐수의 정화방법.
- 제1항에 있어서, 각 단계의 공정은 연속 또는 회분식처리가 가능하도록 전처리의 미세기포부상장치(4)의 처리수를 생물반응조(6)로 유입시키거나, 저류조(3)로 반송시킬 수 있게 배관 및 펌프를 구성하는 것을 특징으로 하는 유기성 폐수의 정화방법.
- 제1항에 있어서, 후단계에 적용시킨 미세기포부상장치(6)(9) 대신에 한외여과막장치(30)를 작용시켜 정화시키는 것을 특징으로 하는 유기성 폐수의 정화방법.
