摘　　要：采用复合型潜流人工湿地对漓江流域农村生活污水进行处理,考察了其对SS、COD、氨氮、TN和TP的去除效果,并且对人工湿地生物相进行分析。结果表明,湿地内植物生长状况良好,栽种培育1个月后即可连续满负荷进水。稳定运行后,人工湿地对SS、COD、氨氮、TN和TP的平均去除率分别超过40%、70%、70%、90%和85%,出水可达GB 18918-2002的一级B排放要求。对人工湿地的生物相进行分析,可观察到有原生动物、后生动物和藻类,说明此时人工湿地系统已经比较成熟。The subsurface flow constructed wetland process was applied to treat Li River rural domestic wastewater,and the removal effects of SS,COD,ammonia nitrogen,total nitrogen and total phosphorus were studied.Moreover,the biological specimens in the wetland were investigated.The results showed that the wetland provided a good medium for growth of plants,and the system could afford the full load of influent after planted for 1 month.After the system operated stably,the removal rates of SS,COD,ammonia nitrogen,total nitrogen and total phosphorus could exceed 40%,70%,70%,90% and 85%,individually.The effluent met the requirements of discharge standard（the first class B standard of GB 18918-2002）.The protozoon,metazoan and algae were found in the soil of wetland,which indicated that the constructed wetland system was already quite mature.
