Claims (6)

  1. 폐수를 오니가 함유된 처리수조에 연속적으로 서서히 공급하여 페수 및 오니로 이루어진 혼합액을 형성시키고; 처리 수조중의 혼합액을 무산소상태 및 계속해서 혐기성 상태가 될때까지 진탕하여 무산소상태에서는 탈질소화를 일으키고, 혐기성 상태에서는 오니로부터 인을 방출시키고 혼합액을 폭기시켜 질산화반응을 유도하면서 오니세균에 의해 인을 섭취케 하고; 진탕 및 폭기단계로 이루어지는 사이클(여기에서 진탕시간 대 폭기시간의 비는 1:1 내지 1:5이다)을 각 사이클이 시간이내에 완결되도록 적어도 회반 복수행하고 진탕 및 폭기된 혼합액을 침강시켜 상동액과 오니로 분리한 후; 상등액은 유출물로서 방류하고, 침강된 오니는 폐수처리용으로 재사용하는 단계로 이루어짐을 특징으로 하여, 호기성 세균을 함유하는 활성오니를 사용하여 폐수로부터 질소 및 인을 제하는 방법.
  2. 제1항에 있어서, 침강단계를 처리 수조에서 수행하며, 이때 처리수조에 대한 폐수의 공급은 중단시키고 필요시에 침강된 오니의 일부는 처리수조로부터 방출시킴을 특징으로 하는 방법.
  3. 제1항에 있어서, 침강단계를 처리수조에서 수행하며, 이때 처리수조에 대한 폐수의 공급은 계속하고 필요시에 침강된 오니의 일부는 처리수조로부터 방출시킴을 특징으로 하는 방법.
  4. 제1항 내지 3항 어느 한 항에 있어서, 질소 및 인의 제거를 확실히 하기위해, 혼합액중의 용존 산소의 농도가 예정치로 조정되도록 폭기 단계에서 공기의 공급속도를 조절함을 특징으로 하는 방법.
  5. 제1항에 있어서, 진탕 및 폭기된 혼합액을 침강 수조에 옮겨 침강수조에서 침강단게를 수행함으로써 폐수를 연속적으로 처리하고, 침강된 오니를 폐수의 처리용으로 처리수조에 반송시킴을 특징으로 하는 방법.
  6. 제5항에 있어서, 질소 및 인의 제거를 확실히 하기 위해, 혼합 액중의 용존 산소의 농도가 예정치로 조정되도록 폭기 단계에서 공기의 공급속도를 조절함을 특징으로 하는 방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
