摘　　要：随着城市对水环境及水资源要求的提高,人工湿地深度处理城市污水处理厂尾水逐渐引起各级部门的重视。部分地区要求污水处理厂出水在满足GB 18198—2002一级A排放标准基础上进一步处理,要求达到《地表水环境质量标准》(GB3838—2002)Ⅳ类水标准。人工湿地处理的出水有进一步提高出水水质的潜力,本工程通过垂直流湿地进一步净化泰安某污水处理厂尾水,从人工湿地池体布置、配水设计等方面探讨,使其主要污染物指标基本达到GB 3838—2002地表水Ⅲ类标准,结合景观设计将处理后水补充城市水体,实现美化环境并节约水资源的设计理念。With the increasing requirements of water environment and water resources,advanced treatment of tail water from sewage treatment plants through constructed wetlands have aroused more and more attention of different related administration departments.Effluent of sewage treatment plant is required to meet the classⅣof Environmental Quality Standard for Surface Water(GB 3838—2002),based on the first grade A criteria of GB 18198—2002.Constructed wetland has the potential to further improve the effluent quality.In this project,the tail wastewater of a wastewater treatment plant(WWTP)in Tai’an is advanced treated through vertical-flow wetland,layout and water distribution design of constructed wetland are discussed,which to ensure main pollutant discharge targets achieveⅢstandard of GB 3838—2002.Coupling with landscape design,effluent from wetland will be discharged to urban landscape river to get the design concept of beautifying environment and saving water resources.
