摘　　要：概述了农村分散生活污水的特点及处理工艺的选择;结合工程实际情况,介绍了垂直流人工湿地的设计概况,总结了设计特点,并指出垂直流人工湿地系统调试运行的注意事项。运行结果表明,在水力停留时间为40.08 h,水力负荷为<0.042 m3.m-2.h-1的条件下,系统对农村分散污水中的主要污染物具有较好的去除效果,出水中污染物COD、TN、TP以及NH3-N的平均质量浓度分别小于60、20、1、15 mg.L-1,达到了城镇污水处理厂污染物排放标准(GB 18918-2002)的一级排放标准。The characteristics of distributed rural domestic sewage and its treatment methods were summarized. Considering the fact of this project, the general design of vertical constructed wetland and characteristics of design were introduced. The matters needing attention in commissioning of vertical constructed wetland system were also proposed. Operatingat4~.~8hhydrau^i~retenti^ntimeanda^werhydmu^ic^adingrate^f~.~42m3.m.2.h~, the results showed that the average removal efficiencies of COD,TN,TP and NH3-N are effective. The average concentrations of COD,TN,TP and NH3-N in effluent were below 60 mg .L^-1,20 mg .L^-1,1 mg .L^-1 and 15 mg .L^-1, respectively .The effluent indexes can reach the first level criteria specified in discharge standard of pollutants for municipal wastewater treatment plant （GB 18918 ~ 2002）.
