摘　　要：为有效治理巢湖兆河流域裴河水环境,净化裴河上游和裴岗社区排水渠河道来水,为下游提供清洁水源补给。本研究采用多水塘活水链技术构建表面流人工湿地,通过合理搭配湿地中的水生植物,适当增加水生植物数量并采取增殖放流等措施,构建丰富多样化的水生态系统,实现湿地效益的可持续发挥。湿地设计水量为2400 m^(3)/d,项目建成后,根据运行后的水质监测数据可知,湿地对COD、NH_(3)-N、TP的削减效率分别为41.88%、29.51%和38.06%。本研究综合考虑了环境、经济、社会和生态效益,对于裴河流域生态环境保护具有重要意义,并为同类型湿地的设计提供了有益借鉴。To effectively manage the water environment of the Pei River in the Chaohu-Zhao River Basin and purify the incoming water from the upstream of the Pei River and the drainage canal of the Peigang community to provide clean water supply to the downstream.This study utilizes the technology of multiple ponds forming a chain of living water to construct surface flow artificial wetlands.Through the rational combination of aquatic plants in the wetlands,appropriate increase in the number of aquatic plants,and measures such as propagation and release,it establishes a diverse and rich aquatic ecosystem,achieving sustainable benefits of wetlands.The designed water capacity of the wetland is 2400 m^(3)/d.According to the water quality monitoring data after operation,the reduction efficiency of COD,NH_(3)-N and TP in wetland is 41.88%,29.51%and 38.06%,respectively.This study comprehensively considers environmental,economic,social,and ecological benefits,which are of significant importance for the ecological environment protection of the Pei River Basin and provides valuable reference for the design of similar wetlands.
