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.
