摘　　要：[目的]研究抚仙湖磷矿开采区入湖河流末端湿地的净化效果。[方法]对东大河河口湿地系统运行参数进行了一周年的测试,分析该湿地系统对磷矿来源污水的净化效果。[结果]湿地对TN、TP、CODCr入湖污染负荷量的平均去除率分别为52%、32%、54%,设计水力负荷为0.67 m3/(m2.d)时处理效果最好。工程已稳定运行6年,达到无能耗、防堵塞、高去除率的运行效果。[结论]该湿地有效削减了磷矿开采产生的入湖污染物负荷量,对保护抚仙湖起到关键的作用。[ Objective ] The study aimed at discussing the purification effect of constructed wetland for treating river water flowing from phosphate mine areas into Fuxian Lake. [ Method ] The running parameters of the constructed wetland were investigated for one year, and the purification effect of the constructed wetland for treating the sewage from phosphate mine areas was analyzed. [ Result ] With the aid of the constructed wetland,the average removal rates of total nitrogen （TN） ,total phosphorus （TP） and CODcr were 52% ,32% and 54% ,and the removal effects were best when the designed hydraulic load was 0.67 m3/（ m2 · d）. Running stably for six years,the constructed wetland had advantages of no power,low resistance and high removal rate. [ Conclusion] The constructed wetland effectively reduced the load of pollutants from phosphate mine areas into Fuxian Lake ,which played important roles in the protection of water quality of Fuxian Lake.
