摘要
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.
