生活垃圾可持续化填埋

Sustainable landfill of municipal solid wastes

通过对中国填埋场现状分析,提出了“可持续填埋”的概念。认为生活垃圾填埋场将从单纯的最终处置场所演变为填埋与中转相结合的场所。填埋场的可持续发展也将从两方面得到体现:一为垃圾降解过程及其副产品处理中以能量形式得到利用,另一方面为稳定化后的垃圾及填埋场本身空间得到再一次的利用。

The sustainable landfill should be applied in MSW treatment process in China,due to the short of energy, resources and land for refuse treatment. The sustainable landfill have double functions, comparing to the traditional landfill （such as sanitary landfill）,and it should be regarded as a large refuse transfer station besides the disposal place. The sustainable development of landfill can be carried out in the following ways：on the one hand,the energy of landfill gas（LFG） should be utilized during the refuse degradation process ;on the other hand, the aged refuse and land in landfill should be reused and recycled after the landfill stabilization.
