四种不同材料在填埋场覆盖的环保效果分析

Analysis Of Environmental Effect On Four Types Of Diverse Material For Landfill Cover

垃圾卫生填埋是城市生活垃圾无害化处理的一种最重要方法，卫生填埋要求对每日垃圾作业面进行覆盖，或在一定堆体厚度后进行中间覆盖，本文通过泥土、浸塑布、彩塑布、0．5mmHDPE膜作为覆盖材料进行试验比较，分析后认为在达到同等环保效果前提下，浸塑布作为临时覆盖是可行的，0．5mmHDPE膜作为中间覆盖是值得推广应用的。

Sanitary landfilling is one of the most important processes for MSW harmless disposal. Sanitary landfill needs either daily cover on daily operation area or the middle cover after some thickness of MSW. The paper gave some contrast on cover material, which are clay, cloth dipped with plastic, color plastic cloth and 0.5mm HDPE membrane respectively. It implies that, On the premise of equal environmental effect, cloth dipped with plastic is acceptable for transient application, whereas 0.5mm HDPE membrane is worthy of being recommended for middle cover material, which can be used repeatedly.
