Abstract

폐기물 매립지로부터 안정화된 토사를 굴착하고, 상기 굴착된 토사를 체의 눈이 10~30mm 크기인 체를 통과하는 토사를 선별하여 폐기물 매립지로부터 선별한 복토재는 중금속, 유해 가스 등의 흡착 능력이 우수한 복토재이며, 폐기물 매립지로부터 복토재를 재활용하는 방법은 부족한 복토재를 저가로 공급할 수 있고 또 신규 매립지의 증설을 억제할 수 있어 환경파괴 및 환경오염 예방측면에서도 매우 우수한 기술이다The excavated soil is excavated from the landfill, and the excavated soil is selected through the sieve with a sieve of 10 to 30 mm in size, and the cover material selected from the waste landfill is a cover material having excellent adsorption capacity for heavy metals and harmful gases. The method of recycling the cover material from waste landfills can supply insufficient cover material at low cost and suppress the expansion of new landfills, which is an excellent technique in terms of environmental destruction and environmental pollution prevention.
