- 외부에서 유입된 오폐수를 오폐수 이송관을 통해 반응조로 이송하는 유입단계와; 저류조로 유입된 오폐수를 무산소혼합조로 연속적으로 이송하면서 주반응조에서 반송된 슬러지와 무산소 조건에서 혼합되고, 상기 무산소 혼합한 오폐수는 유동상 담체가 충진된 생물막반응조로 자연 이송되어 미생물의 활성화 및 보유량을 극대화시켜 오폐수를 1차 정화처리되고, 상기 생물막반응조에서 처리된 오폐수는 주반응조로 자연 이송되어 폭기, 침강, 배출 및 휴지를 반복하여 최종 정화처리하는 정화처리단계와; 상기 정화처리 완료 후 발생된 침전 슬러지는 슬러지 저류조로 이송하고 상등수는 배출기에 의해 외부로 방류하는 회분식 오폐수 처리방법에 있어서,상기 무산소혼합조(20)는 주반응조(40)에서 반송되는 슬러지의 반송비를 15% 내지 30%로 유지시키고, 용존산소의 농도를 0.3mg/ℓ 내지 0.5mg/ℓ로 유지시킴을 특징으로 하는 회분식 오폐수 처리방법.
- 청구항 2에 있어서, 상기 생물막반응조(30)에 유동상 담체(33)를 15% 내지 30% 정도 충진시켜 사용함을 특징으로 하는 회분식 오폐수 처리방법.
- 청구항 3에 있어서, 생물막반응조(30) 및 주반응조(40)가 외부에서 유입되는 공기로 오폐수를 폭기하여 호기성 상태로 유지시켜 주는 폭기과정과; 폭기된 오폐수에 함유된 슬러지의 중력침강을 유도하여 침전 슬러지와 상등수로 고액분리하는 침전과정과; 고액 분리된 상등수를 외부로 배출함과 동시에 침전된 슬러지를 슬러지 인발펌프(43)를 이용하여 슬러지 저류조(50)로 이송하는 배출과정; 및 일정량의 상등수 배출이 진행되는 동안 오폐수 유입이 중지되고 배출이 완료되면 오폐수가 다시 유입되어 폭기단계를 준비하는 휴지단계를 거침을 특징으로 하는 회분식 오폐수 처리방법.
