Abstract

Biofilm process is preferred to activated sludge process in small domestic wastewater treatment plant because of its simplicity in operation and maintenance. Column reactor filled with waste ceramics and with waste plastics was used to remove pollutants in restaurant wastewater. COD removal at 18 hours of hydraulic retention time (HRT) gave 93.7%, COD removal during the experimental period, where maximum COD removal was observed. Under same condition, average removal of total nitrogen and total phosphorus were 82.3% and 25.9%, respectively Organic and nitrogen were efficiently removed with the HRT of 18 hours or more.

생물막 공정은 소규모 오수처리공정에서 운전과 유지가 간단하기 때문에 활성 슬러지 공정보다 각광을 받고 있다. 담체로 폐토기와 폐비닐을 충진한 컬럼형 반응기로 실폐수인 식당 폐수의 오염물을 제거하는 실험을 수행하였다. 실험결과, 수력학적 체류시간 (HRT)이 18 hr일 때 COD 제거율은 93.7%로 칙대 COD 제거율을 보였다. 같은 조건에서 T-N과 T-P의 평균 제거율은 각각 82.3%, 25.9%를 나타내었다. 따라서 HRT를 18 hr 이상일 때 유기물과 질소의 제거 측면에서 비교적 만족할 만한 처리효율을 얻을 수 있었다.
