摘　　要：[目的]为科学处理农村生活污水提供参考。[方法]将生物接触氧化与人工湿地工艺相结合对农村生活污水进行处理。[结果]连续4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、TP和SS的平均去除率分别为85.9%、92.8%、80.1%、83.6%和91.0%,出水水质达到了《城镇污水处理厂污染物排放标准》(GB18918-2002)的1级A标准,人工湿地对主要污染物的平均去除率均在50%以上。[结论]生物接触氧化与人工湿地工艺相结合可用于处理广州地区农村生活污水。[Objective] The aim was to provided scientific reference for treating rural sewage.[Method]Biological contact oxidation（BCO） combined with constructed wetlands（CWs） was applied.[Result]The results of trial operation over continuous four months showed that the whole treatment system had stable operation,the average removal efficiencies of COD,BOD5,NH＋4-N,TP and SS were as high as 85.9%、92.8%、80.5%、83.6% and 91.0%,respectively.The effluent quality reached the specification for level A of grade 1 in Discharge Standard of Pollutants for Municipal Wastewater Plant（GB18918-2002）.The average removal rates of main pollutants by CWs were all above 50%.[Conclusion] Biological contact oxidation combined with constructed wetlands could be used for treatment of rural domestic sewage in Guangzhou.
