Abstract
Municipal landfill leachate, a major source of soil contamination and ground water pollution, causes serious environmental problems. To investigate the removal efficiency of pollutants in the leachate by sand, briquet ash, fly ash, and activated carbon columns, COD and some pollutants in the leachate passed through each column for 8 weeks were examined. Average COD removal efficiency for 8 weeks was 83%, 45%, and 43% by activated carbon, briquet ash and fly ash columns, respectively. COD was not effectively reduced by sand column. Average
쓰레기 매립장 침출수를 모래, 연탄제, fly ash 및 활성탄을 각각 충전시킨 column에 8주간 매주 통과시켜 오염물질 제거율을 조사한 결과 COD는 활성탄 column에서 8주동안 평균 83%이상 제거되었으며, 연탄재와 fly ash column에서는 시간이 경과함에 따라 제거되는 비율이 낮아지는 경향이었으나 8주 평균 각각 45% 및 43% 제거되었고, 모래 column에서는 거의 제거되지 않았다.
