摘　　要：以生态氧化池作为垂直流人工湿地的强化前处理工艺，将组合工艺应用于污水处理厂尾水深度处理，简要介绍了工艺流程和设计参数，并对稳定期的运行结果进行了分析和讨论。连续12个月的水质监测数据表明，深度处理系统运行稳定，对COD、BOD5、NH4^＋-N和TP的平均去除率分别为61．8％、64．4％、82．6％、75．2％，出水水质优于《地表水环境质量标准》（GB3838—2002）的Ⅳ类标准。生态氧化池和垂直流人工湿地对主要污染物的去除特征存在显著差异，其中垂直流人工湿地对上述污染物的平均去除率为50％～80％。Vertical flow constructed wetland （VFCW） and ecological oxidation tank （EOT） as the enhanced pretreatment process, were used for the advanced treatment of effluent from municipal wastewater treatment plant. The technical process and design parameters were introduced, the operation results during the steady period were analyzed and discussed. The monitoring data of water quality over continuous twelve months suggested that the advanced treatment system operated steadily, with the average removal rates of 61.8%, 64.4%, 82.6% and 75.2% for COD, BOD5, NH4^＋ - N and TP, respectively. The effluent quality was superior to the Ⅳ criterion specified in the Environmental Quality Standards for Surface Water （ GB 3838 - 2002）. Meanwhile, a remarkable difference in removal of the pollutants was observed between VFCW and EOT, the average removal rates of the pollutants by VFCW were 50% to 80%.
