岩溶型尾矿库渗滤液重金属污染防治技术研究进展

Research progress on heavy metal pollution prevention technology of leachate from Karst-type tailings pond

文章通过对岩溶型尾矿库渗滤液重金属污染防治技术相关方法进行研究,结果表明可渗透反应墙(PRB)处理污染地下水具有初期建设投资低、可以根据所要处理的污染物质灵活选择、运行期不需要能量供给而且处理设施不会占用宝贵的土地资源等显著优点,是岩溶型尾矿渗滤液治理方面最具发展前景的方法之一。

This paper makes a research on the related methods of heavy metal pollution prevention technology of leachate from karst-type tailings ponds. The results show that permeable reactive barrier （PRB） has several advantages in treating polluted groundwater. These advantages include low construction investment in early stage, flexibility of using suitable treating methods according to different contaminants, and no energy consumption in operating period; moreover, no land resources will be occupied by treatment facilities. It is one of the most promising methods in treating leachate from karst-type tailings ponds.
