摘　　要：选用芦苇+凤眼莲和灯心草+凤眼莲+菹草两种人工湿地植物组合构筑了两种小试人工湿地,取内江市高桥镇垃圾填埋场的垃圾渗滤液进行试验研究。结果表明,这两种人工湿地对渗滤液中的重金属均有良好的去除效率,特别是灯心草+凤眼莲+菹草的组合,对重金属铅、镉、铜、锌的去除效率均在95%以上。表现出良好的发展应用前景。The bulrush＋eichhomia crassipes and juncus effuses＋eichhomia crassipes＋potamogeton crispus wetlands plants combination were used to construct two kinds small scale wetlands. The inlet leachate sampled from landfill situated on Gao-qiao town in Neijiang city was analyzed, the results indicated that both the constructed wetlands had excellent removal efticiency for heavy metal, especially the juncus effuses＋eichhomia crassipes＋pota- mogeton crispus constructed wetlands. It can reach more than 95% removal efficiency in lead, cadmium, cuprum, and zinc.
