| 摘 要： | 选取沸石、煤渣、沸石+煤渣作为基质,研究3种不同基质人工湿地对电镀重金属(Cr,Zn)污水的净化效果。结果表明,3种基质对于重金属Cr,Zn均有明显的去除效果,去除率都在74%以上;煤渣和沸石发生了协同作用,对重金属Cr的去除效果好于其单独使用;种植植物的煤渣与沸石混合基质人工湿地去除重金属Cr,Zn能力优于种植植物的沸石基质人工湿地。

Study of Different Substrates Used in Constructed Wetlands for Removal of Plating Heavy Metal (Cr,Zn) |
| |
| Abstract: | Zeolite ,cinder ,zeolite-cinder mixture are used as substrates and the purification effects of three constructed wetlands with different substrates have been studied .The principal results show :three substrates have obvious removal ef-fects for heavy metal Cr ,Zn and the removal rates can reach above 74% ;when the cinder is cooperated with zeolite ,the mixture has higher removal efficiency of heavy metal Cr than that by using the single one ;the zeolite-cinder mixture system with plant cultivated has a better effect on heavy metal Cr ,Zn removal than the zeolite system with plant cultivated . |
