锅炉灰渣填埋场防渗处理技术

Anti-seepage treatment technology of boiler ash slag landfill

锅炉灰渣为一般工业固体废物中的第Ⅱ类固废,为满足环保要求和填埋场承载能力,对防渗结构、渗滤液处理及排液系统等进行了详细的分析。选择使用人工合成衬层防渗技术、HDPE(高密度聚乙烯)土工膜防渗材料,并对库区底部和边坡防渗层结构和渗滤液处理系统进行加强设计,解决了灰渣场防渗,避免随意丢弃现象带来的粉尘污染及地下水污染的问题。

The boiler ash slag is the second kind of industrial solid waste. In order to meet the requirement of environmental protection and the carrying capacity of landfill,the anti-seepage structure,the treatment of leachate and the drainage system are analyzed in detail. In this paper,the synthetic lining anti-seepage technology and the HDPE( High-Density Polyethylene) Geomembrane anti-seepage material are selected,and the structure of the anti-seepage layer and the treatment system of the leachate at the bottom of the reservoir area and the slope are strengthened. It solves the problems of anti-seepage of ash field,avoiding the dust pollution and groundwater pollution caused by the phenomenon of random throwing.
