Abstract
Recently, detections of huge amount of wastes in the unsanitary landfills at a residential development sites were reported. Because the sites were the residential development sites, all landfilled wastes should be removed for the constructions. Therefore the way that the unsanitary landfills were excavated and then the wastes were sorted into three categories such as soils, noncombustibles, and combustibles was selected as the best method. Soils and noncombustibles could be recycled in the sites and combustibles could be compacted and be relandfilled in a smaller area.
Key Words: unsanitary landfill; residential development sites; excavation; noncombustibles; combustibles; landfill compaction
요지
택지개발사업현장에서 발생하는 대규모 매립쓰레기의 합리적인 처리를 위하여 매립쓰레기를 굴착하여 토사류, 불연물류, 가연물류 등으로 선별하고, 토사류, 불연물류는 현장 재활용하고, 가연물류는 별도 처리하는 방안이 최적 방안으로 제시되었다. 가연물류는 소각하는 것이 일반적인데, 높은 소각비용으로 경제성을 확보하기 위하여 현장압축매립공정이 새로운 대안으로 평가받고 있다. 현장압축매립공정은 일반매립공정보다 좁은 면적에 매립이 가능하며, 소각공정에 비해 경제적인 장점을 가지고 있다.
핵심용어: 비위생매립지; 택지개발현장; 굴착; 불연물류; 가연물류; 압축 매립
