摘要
针对盐城市大丰污水处理厂出水为一级A标准,直排入河将污染周边水系,影响周边环境生态安全等问题,采用“强化净化湿地+深度涵养湖泊”的组合湿地工艺对污水处理厂尾水进行深度净化,结果表明,组合人工湿地系统对COD、NH3-N、TN及TP的平均去除率分别为76.01%、54.83%、63.46%及40.72%,该技术对污水处理厂尾水深度净化的效果较好,出水能稳定达到《地表水环境质量标准》(GB 3838—2002)III类标准。
To solve the current problems of organic pollutants,nitrogen,and phosphorus in tail water from the Dafeng Sewage Treatment Plant in Yancheng City,the combined wetland technology of"enhanced purifi cation wetland+deep conservation lake"was adopted to deeply purify the tail water of the sewage treatment plant.The results showed that the combined constructed wetland system had a good effect on the deeply purifi cation of the tail water of the sewage treatment plant,and the average removal rates of COD,NH3-N,TN and TP were 76.01%,54.83%,63.46%and 40.72%,respectively.During the operation period of the system,the effl uent basically reached the Class III standard of the Surface Water Environmental Quality Standard(GB 3838—2002).
