摘  要：
选用芦苇作为人工湿地的植物,构建了4个规格为5 m×10 m×1.5 m的人工湿地,并进行了实验。结果表明:人工湿地对污泥中重金属Pb、Cd、Hg、As及渗滤液中COD均有一定的去除作用。系统经过6个月的试运行后,测得上述4种重金属的去除率在49%~65%之间;2013年8~11月期间测得的渗滤液中COD去除率不太稳定,最高为63.5%。本研究为合理利用人工湿地技术对海水淡化厂污泥进行稳定和无害化处理提供参考。

摘  要：
The reed was chosen to construct four wetlands with a size of 5 m×10 m×1.5 m and the experiments were conducted with these wetlands. The results indicated that the constructed wetlands had some efficiency for removal of heavy metal such as Pb, Cd, Hg, As in sludge and COD in percolate. After 6 months of the system running, the removal rate of the above heavy metals was between 49%-65%. But the removal rate of COD in percolate was not very stable and the highest value was 63.5% during the period of August to November 2013. The study provided some references for reasonable application of constructed wetland technology in stabilities and harmlessness of sludge from seawater desalination.
