摘　　要：目的改善八干渠再生水景观河道当前水质.方法采用生物浮岛技术建立生态示范工程,并确定以旱伞草、慈姑、美人蕉等为主的高等植物构建生物浮岛与水体自净相结合的恢复体系.结果生物浮岛技术对再生水景观河道的水质具有一定的保持和净化作用,其中TP出水质量浓度约为0.2～0.38 mg/L,TN出水质量浓度约为2.0 mg/L,NH3-N出水质量浓度约为0.8～2 mg/L,NO3-N出水质量浓度约为0.25～1.0 mg/L,CODcr出水质量浓度约为30～70mg/L.结论生物浮岛技术对TN和TP均有较稳定的净化效果,而对CODcr和NH3-N的净化效果并不理想,其中温度是影响示范工程处理效果的重要因素.The paper aims to clean and maintain current water quality that is the landscape of Baganqu re- claimed water in a river and establish ecological demonstration project by the use of biological floating island technology. We built a combination of biological floating island with water self - purification recovery sys- tem in the use of higher plants such as parasol grass, the arrowhead and Canna. The demonstration project has certain maintenance and purification to the resurgent water quality in landscape river. The TP density is approximately 0. 2 -0. 38mg/L, TN density is approximately about 2. 0 mg/L, the NH3 -N density is ap- proximately the 0. 8 ~ 2 mg/L, NO3 - N density is approximately 0. 25 ~ 1.0 mg/L, CODcr density is ap- proximately 30 ~ 70 mg/L. The demonstration project has the stable purification effect to TN and TP, but it is not ideal to CODcr and the NH3 - N nitrogen purification effect, the temperature affects the demonstration project processing effect the important attribute.
