摘　　要： 城市生活垃圾填埋场防渗层的建设,对防止渗滤液污染扩散具有决定性的作用。本文介绍了多种防渗方式和防渗材料,着重介绍了水平防渗和垂直防渗及其在城市生活垃圾填埋场的应用状况,同时介绍了有机合成材料中的高密度聚乙烯膜及其国产产品的性能。指出在经济条件允许的情况下,采用水平防渗方式对防止渗滤液污染效果更佳,采用人工合成材料,辅以使用天然材料进行防渗具有更好的环境经济效益。 The construction of liner system is crucial for municipal household garbage landfill to prevent contamination of leachate from diffusing into the groundwater. Many anti-seepage modes and different impervious materials had been introduced in the paper. Applied status of horizontal anti-seepage mode and vertical anti-seepage mode in our municipal household garbage landfill wereintroduced particularly in the paper, at the same time, property of high density polyethylene and it＇s Chinese-made product were introduced in full in the paper. It had been pointed out that horizontal anti-seepage mode used in landfills to prevent contamination of leachate better than under allowable status of economical condition. It would have better environmental and economical benefit of controlling seepage for using synthetic materials with subsidiary natural materials in the landfills.
