- Abstract
- 본 연구의 목적은 사용종료 비위생매립지의 안정화 정도를 평가하고 안정화되지 않은 사용종료 매립지의 재정비 방안을 도출하는데 있다. 안정화 정도는 기존 사용종료 비위생매립지 21개소의 매립폐기물 시료를 채취하여 그 성상을 분석하여 평가하였다. 물리적 성상으로는 토사, 유기물, 가연성 및 불연성으로 분석하였다. 그 결과 매립폐기물 시료를 채취한 9개소의 비위생매립지는 사용종료 후 10년 이상 경과되었음에도 완전한 안정화가 이루어지지 않았으며, 사용종료 비위생매립지의 재정비가 시급함을 알 수 있었다. 비위생매립지의 물리적 성상중 토사 함량이 높았으며 가장 높은 함량은 89.96%이었다. 이와는 달리 위생매립지의 경우는 9.89~11.12%로 토사함량이 낮았다. 따라서 선별이적처리에 의해 회수된 토사는 재정비를 해야하는 비위생매립지의 복토재나 건설재료로의 재활용할 수 있을 것으로 평가되었다.
The aim of this study was an evaluation of closed non-sanitary landfill's stabilization degree and a determination of its an optimal reclamation method. In order to evaluate the stabilization degree, physical compositions of landfill wastes in 21 closed non-sanitary landfills were analyzed. There were 4 major items such as cover soils, organics, combustibles and incombustibles. With respect to the results of physical compositions, it was determined that the waste in 9 sampling sites of closed non-sanitary landfills after 10years of the relief time was not fully stabilized. The closed non-sanitary landfills must be reclaimed as soon as possible. The main material in closed non-sanitary landfills was cover soils and the highest content was 89.96%. Otherwise, the contents in sanitary landfills was small and 9.89~11.12%. Therefore, it was evaluated that the recovered soil by sorting transfer treatment could be reused as on-site cover soils of the reclamating non-sanitary landfills and/or constructing materials.
