도시생활폐기물에 침출수 농축 주입 : 그에 따른 생화학적 현상과 실제적인 결과
( T. Bouchez ),( M-l. Munoz ),( C. Aran ),( R Mailly ),( H. Robain ),( C. Duquennoi ) 한국폐기물자원순환학회 2002 APLAS Vol.2002 No.2
물리화학적 농죽과정에 의한 짐줄수 처리는, 처리되어야 하는 농죽된 짐줄수를 발생시킨다. 도시생활 폐기물에 침출수를 주입하는 방법이 종종 제안되어져 왔다. 파일럿규모의 연구를 통해, 주입된 침출수 농도에 의한 오염부하가 회복된다는 것을 관찰하였다. 또한, 대조군과 비교하여, 실험 장치내에서 안정적인 메탄생성균의 활동이 늦어진다는 것을 관찰하였다. 200일 이상 운전된 대조실험장치의 침출수내에 생존하는 미생물은 상당히 낮게 존재하는 것으로 나타났고, 이는 미생물 활성에 저해 효과를 유발했음을 알 수 있다. 실험결과를 통해, 침출수 농축주입이 수행되는 full-scale 매립 셀에 대해서도 확인하였다. 폐기물 분해과정에 대한 적합성을 평가하기 위해, 침출수의 특성은, 주입되기 전에, 측정되어져야 함을 알 수 있었다. Leachate treatment by physico-chemical concentration procedures generates leachate concentrate that have to be handled. Injection in the body of MSW has sometimes been proposed. In a pilot-scale study, we observed that a large part of the injected leachate concentrate pollution load was restituted. We also observed that the onset of stable methanogenesis was delayed in the test pilot compared to the control one. Viable bacterial counts in the leachate of the test column had remained several order of magnitude lower for more than 200 days, indicating a possible inhibitory effect on bacterial development. Our lab-scale results were corroborated by observations made on a full-scale landfill cell where leachate concentrate injection was performed. We conclude that certain characteristics of the leachate concentrate should be monitored before injection in order to evaluate its compatibility with waste degradation processes.
