摘　　要：针对水体富营养化问题,利用多级生态塘植物修复技术,对西湖上游的两股溪流进行生态拦截与修复。实际运行结果表明,该工艺净化效果良好,对主流水体中的TN、TP、NO-3-N和COD的累计去除率分别为42.5%、42.8%、52.9%和52.6%,对支流水体中的TN、TP、NO-3-N和COD的累计去除率分别为62.1%、77.3%、69.3%和59.6%,出水水质分别达到《地表水环境质量标准》(GB 3838—2002)Ⅴ类和Ⅳ类标准。To address the problem of water body eutrophication, the multi-stage ecological pond phytoremediation technology was used to intercept and remedy two streams from West Lake upstream. The practical results showed that the process had good purification effect. The cumulative removal rates of TN, TP, NO3- - N and COD in the main stream were 42.5% , 42.8% , 52.9% and 52.6% respectively, and those in the tributary were 62.1% , 77.3% , 69.3% and 59.6% respectively. The effluent quality of the main stream and tributary could meet the class V and IV criteria specified in the Environ-mental Quality Standards for Surface Water （ GB 3838 - 2002）.
