摘要
城市固体废弃物填埋场是许多国家最终处置固体废弃物的主要方法,其衬垫系统是填埋场整个系统中最关键的部位。主要介绍了填埋场衬垫系统的发展及其3种主要衬垫材料,并对三者进行了互比较,指出使用GCL是未来衬垫系统材料应用的发展方向。但由于经济和效益之间的矛盾,使得能否真正实施符合高标准高要求的衬垫系统成为我国当前填埋技术中的突出问题。结合我国国情,指出在选择和设计衬垫系统时应因地制宜,切合实际,建造有地方特色的垃圾填埋场。最后,对衬垫干裂、衬垫厚度以及衬垫系统中的稳定性等问题进行了讨论。
Landfill is a primary method of ultimate disposition of municipal solid waste in many countries. The liner system of such disposal field is the key part of the whole system. This paper principally introduces the development of liner system in landfill site and its three main liner materials and analyses them comparatively, then points out that making use of GCL is the trend of the applicable liner in future. However, because of the contradiction between cost and effect, it is a prominent problem of current landfill technology in China whether we can really implement high standard liner system. Up to our country's situation, this paper suggests that selecting and designing liner systems should be based on local conditions.
