摘　　要：武夷山市人工湿地系统采用水解酸化+接触氧化+垂直流人工湿地处理工艺处理城市生活污水,经过5年多的运行,结果表明系统对COD的净化效果好。近17个月的监测数据显示,COD的去除率超过92%,系统出水水质达到《城镇污水处理厂污染物排放标准》的一级A标准。此外,人工湿地系统处理城市生活污水的耗能低(平均的耗电量为0.14 kWh/m3),节省日常的运行费用。Hydrolysis acidification, contact oxidation and vertical flow constructed wetland process have been employed in the treatment of urban sewage in Wuyishan city artificial wetland system for more than five years. The results show that the system is effective for lowering the chemical oxygen demand （COD）. The monitoring data of the recent 17 months show the removal rate of COD has reached more than 92%. The system effluent quality achieves the first class （A） of ＂Standard for discharge of pollutants from sewage treatment plants in cities and towns＂. In addition, the power consumption of artificial wetland system is low（ the average power consumption is 0.14 kw · h/m^3 ） in the treatment of municipal sewage with daily running costs being lowered.
