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。
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 effects 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.
