摘　　要：将生态氧化池/生态砾石床组合工艺作为强化型前处理系统,与垂直流人工湿地工艺相结合,用于处理城市污水处理厂尾水,详细介绍了工艺流程和设计参数,并对主要技术经济指标进行了分析。连续5个月的试运行结果表明,整个处理系统运行稳定,对COD、BOD5、NH4+-N和TP的平均去除率分别为70.3%、69.0%、91.9%和83.1%,出水水质达到《地表水环境质量标准》(GB 3838—2002)中的Ⅲ类标准。垂直流人工湿地对主要污染物的平均去除率均在55%以上。Vertical flow constructed wetland （VFCW） technology and intensified pretreatment system integrated by ecological oxidation tank and ecological gravel bed were combined for treating tailwater from municipal wastewater treatment plant. The technical flow and design parameters were introduced, and the main technicoeconomic indices were analyzed. The results of testing operation over continuous five months show that the whole treatment system has stable operation, with the average removal rates of COD, BODs, NH4^＋ - N and TP as high as 70.3% , 69.0% , 91.9% and 83.1% , respectively. The effluent quality reaches the class Ⅲ criteria in the Environmental Quality Standard for Surface Water （ GB 3838 -2002）. The average removal rates of main pollutants by VFCW are all above 55%.
