填埋场粘性土防渗层中强化微生物对垃圾污染物的净化作用

PURIFICATION OF ARTIFICIAL MICROBE TO WASTE POLLUTANTS IN THE CLAYEY SOILS LINES UNDER LANDFILL

如何铺设价廉物关的防渗层,又不需对垃圾渗滤液进行处理,达到环保效果好、成本低的目的,是填埋场防渗衬垫铺设所追求的,但由于科学理论及技术条件的限制,这个目的一直没有达到。通过添加营养菌液强化厌氧微生物对污染物的净化作用,在实验室用土柱进行模拟实验及天然的土柱淋滤净化对比实验,研究了粘性土垫层土中添加营养菌液后,厌氧微生物对垃圾污染物的净化能力的变化,得出了加入厌氧微生物菌液后,可显著地提高微生物在土中对垃圾污染物的净化能力的结论。这为开发价廉物美的垃圾场防渗衬垫打开了思路,为有污染问题的垃圾场提供了一种用微生物治理的方法。

The aim that is how to pave efficiency liners in low cost and have a good impact on environment without any dealing with the leachate of landfill, which is being expected to pave liners under landfill, doesnt come to true because of the limited methods of science and technology. Two kinds of leaching purification experiment have been done in lab and the results of that have been compared by using simulated earth column and natural earth column which contains additive liquid culture in order to enhance purif...
