摘　　要：杭州虾龙圩河由于多年污染,河道水质严重黑臭,自净能力遭到破坏。本研究通过综合利用底泥污染物削减、生物接触氧化水质净化、造流曝气及水生生态系统修复等技术对虾龙圩河进行治理。结果显示,此项综合技术对城市河流污水具有良好的污染物去除性能,COD、NH3-N和TP的去除率分别可达到73.3%、80.1%和81.7%。通过1年的运行与养护,虾龙圩河治理段的水质、生态环境等有了明显改善,没有发生过水华及黑臭现象,河道水体具备了较强的自净能力。Due to years of pollution, the water quality of Hangzhou Xialongwei River has been polluted se- riously, and it has become a malodorous black river, the capacity of self-purification has been destroyed. In this study, the comprehensive techniques including sediment pollutant reduction, biological contact oxidation water purification, making the river flow aeration and aquatic ecosystem restoration were used for improving the water quality in Xialongwei River. The results showed that the integrated technique had good purification efficieneies for polluted urban river water,the removal rates of COD, NH3-N and TP reached 73.3% , 80.1% and 81.7% , respectively. After a year of operation and maintenance, the water quality and ecological environment have been significantly improved in the processed part of Xialongwei River, there are not the phenomena of algal bloom, black or stink, the river water has a strong self-purification ability already.
