摘要： 针对富营养化严重的新角浦河，构建了梯级生态浮床系统(SFTW)，开展河道水体的净化处理示范工程研究.结果表明，该系统对CODCr，NH4+-N，TN和TP的去除率最高分别可达21.26%，29.07%，37.95%和20.74%.治理后的示范河段除TN仍为劣V类外，CODCr，NH4+-N和TP出水浓度均达到V类标准，基本达到示范工程的预期目标.通过对浮游藻类的种类和富营养化指数（NQI）进行监测发现：该河段水质污染严重，所有采样点水质均严重富营养化，但SFTW对水质有一定的改善，NQI下降了3.26~12.33，说明该技术具有应用前景。

Abstract: By constructing Staged Floating Treatment Wetlands (SFTW) for purification of Xinjiaopu River in Shanghai, the improvement effect of eutrophic water quality was investigated. The results showed that the best removal efficiencies on CODCr, NH4+-N, TN and TP are 21.26%, 29.07%, 37.95% and 20.74%, respectively. According to Surface Water Environment Criteria of China (GB 3838—2002), all the measured water quality indexes except that of TN reached Grade V, basically meeting the requirements.The evaluation result of phytoplankton doinant species and NQI indicated the water quality was at heavy-eutrophication,but NQI decreased 3.26~12.33. The system has good application prospect.
