摘　　要：采用分段进水接触式A^2/O工艺处理旅游度假村生活污水,处理规模为150 m^3/d,出水水质可达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级B标准。运行结果表明,在污水随旅游季流量波动大、低碳氮比和低碳磷比情况下,处理系统实现了良好的脱氮除磷效果,并能有效抵抗水量冲击负荷。A kind of step-feed biological contact A^2/O process was used to treat rural domestic sewage of a tourist resort. The design capacity of the project was 150 m^3/d and the effluent had to meet the first class B criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. The long-term operation results showed that the simultaneous removal of nitrogen and phosphorus was achieved and the process had good resistant capacity to water quantity shock-load when the raw sewage exhibited characteristics of low C/N ratio, low C/P ratio and large flow fluctuation in the peak tourist season.
