摘　　要：针对城市雨源型河道水质特征,利用现有条件采用原位水质净化处理系统,该系统采用了改良型A^2/O+人工湿地+氧化塘组合工艺,最大处理能力为600 m^3/d,设计出水水质主要指标达到《地表水环境质量标准》(GB 3838—2002)V类标准(NH3-N≤4.8 mg/L)。实际运行数据表明,该系统在常规污染物削减达标的情况下能进一步对特征痕量有机污染物进行有效去除,具有典型的示范意义。According to the water characteristics of the rain source-type urban river, an in-situ water purification system which was based on the local conditions was used. The main treatment processes were the improved A^2/O process, constructed wetland and oxidation pond. The maximum capacity of the system was 600 m^3/d, and the design effluent quality should meet the class V criteria specified in the Environmental Quality Standards for Surface Water （GB 3838 -2002 ） with ammonia nitrogen of less than 4.8 mg/L. The operation data indicated that the system could effectively reduce conventional pollutants and remove trace organic pollutants. It has the typical demonstration significance.
