Abstract
In order to investigate the quantitative and qualitative properties of leachate with different composition of MSW in solid waste landfill, three lysimeters filled with bottom ash only (Lysimeter A), bottom ash 70%+municipal solid waste 30% (Lysimeter B), and municipal solid waste only (Lysimeter C) respectively were operated under actual meteorological conditions. From the results, Lysimeter A and Lysimeter B were much higher than Lysimeter C in terms of cumulative generation rates of leachate. The pH in leachate from Lysimeter A are in the range of pH 9 to 11, however, the pH of the leachate was gradually changed to the neutral with time. In the case of
침출수의 수량 및 수질변화를 평가하기 위하여 세 종류(소각재 100%, 소각재 70%+일반생활폐기물 30%, 생활폐기물 100%)의 모형매립조를 실제 기상조건하에서 운영하였다. 실험결과, 누적 침출수 발생률이 모형매립조 A와 B가 모형매립조 C보다 높은 것으로 나타났다. 모형매립조 A는 pH가 pH 9~11의 범위였으나 시간이 경과하면서 중성으로 점차 변하였다. 염소이온은 소각재를 매립한 모형매립조 A와 B가 높은 것으로 나타났으나 모형매립조 C의 경우 낮게 나타났다. 생활폐기물을 충전한 모형매립조 C의 경우 침출수내의 유기물 농도가 다른 모형매립조보다 높게 나타났다.
