- 하/폐수 원수를 1차 점전조(1)에 유입시켜 일점시간 머물게 하여 조대입자를 침전시키고, 분배 탱크(2)로 유도하여 분배 탱크내로 유입된 하/폐수 원수의 일부는 암모니아와 이온 교환할 수 있고 질산화균이 부착되어 있는 필터(4)로 보내고 나머지는 혐기조(3-1), 무산소조(3-2) 및 호기조(3-3)으로 구성된 반응조(3)의 통기성 미생물의 혐기조(3-1)으로 보내고, 필터(4)를 통과한 원수와 혐기조(3-1)를 거친 원수를 무산소조(3-2)에서 탈질소화한 다음, 호기조(3-3)으로 보내어 윈수중의 잔여 암모니아성 질소를 질산화처리하고 잔여 생물학적 요구량을 처리하고 동시에 탈인화한 후, 호기조(3-3)처리수의 일부분을 무산소조(3-2)으로 반송하여 재차 탈질소화하고, 2차 침전조(5)로 보내어 세포와 처리수를 분리하는 것으로 이루어지는 하/폐수중의 질소와 인의 생물학적 인속 처리 공정.
- 제 1 항에 있어서, 상기한 필터(4)는 MO,A12O3,mSiO2·nH2O(M은 알칼리 토금속)으로 표시되는 함수 알루미늄을 주성분으로 하는 천연 제오라이트로 구성됨을 특징으로 하는 공정.
- 제 2 항에 있어서, 상시한 필터(4)는 재생수의 주입없이 제오라이트에 미생물을 입혀서 재생됨을 특징으로 하는 공정.
- 제 2 항 또는 제 3 항에 있어서, 상기한 필터(4)는 제오라이트 표면에 니트로스모나스(Nitrosomonas),니트로박터(Nitrobacter)와 같은 질산화균을 입혀서 제오라이트내로 이온 고환되어 축적되는 암모늄이온을 질산화시킴으로서 재생수의 유입없이도 제오라이트의 이온 교환 용량이 유지되어짐을 특징으로 하는 공정.
- 제 1 항에 있어서, 필터(4)로 분배되는 하/폐수의 양은 분배 탱크(2)에서 분배되는 하/폐수 총량의 10내지 40%로 하는 것을 특징으로 하는 공정.
- 제 1 항에 있어서, 호기조(3-3)으로부터 무산소조(3-2)로 반송되는 호기조 처리수의 반송량은 무산소조(3-2)로부터의 유입량에 대하여 15 내지 30%임을 특징으로 하는 공정.
