摘　　要：详细介绍了高适应性人工湿地处理长江经济带某污水处理厂尾水工程的设计内容,可为建设场地复杂或用地紧张的同类型人工湿地的设计提供借鉴。设计总规模为14.8×10^4m^3/d,其中1.5×10^4m^3/d分流至生态河道,13.3×10^4m^3/d分流至高适应性复合人工湿地,人工湿地工艺采用四级生态渠+表流湿地+沉水植物区,最后出水25%用于回用,75%排至长江。实际运行中,湿地进水水质基本达到《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准,出水水质优于《地表水环境质量标准》(GB 3838-2002)中Ⅳ类水指标限值。The design process of highly adaptable constructed wetland used for advanced treatment of effluent from a sewage treatment plant in the Yangtze economic zone was introduced in detail,and it could provide references for designing the similar constructed wetland that had complex site conditions and less construction land.The effluent from sewage treatment plant was the influent of this project with treatment capacity as 14.8×10^4 m^3/d,in which,the influent of 1.5×10^4 m^3/d flew into the ecological river,the influent of 13.3×10^4 m^3/d flew into the constructed wetland.The treatment processes of constructed wetland were composed by four stages eco-ditch,surface flow wetland and submerged macrophyte zone.25%of the final effluent was used for recycling,and 75%of the effluent was discharged to Yangtze River.After investigation,the influent indexes reached basically standard A of the first class of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).The effluent indexes were better than those of the classⅣstandard of Environmental Quality Standards for Surface Water(GB 3838-2002).
