摘　　要：以淹没式生物膜-稳定塘组合技术处理农村生活污水,系统取消了二沉池、污泥回流。运行结果表明:系统对COD、NH3-N、TN和TP的平均去除率分别为84.33%、97.02%、80.18%和77.34%,出水平均浓度分别为14.88,1.06,9.92,0.53 mg/L。淹没式生物膜系统出水污泥浓度为零,稳定塘出水水质良好,可满足中水回用。The submerged biofllm-stabilization pond composite technology was used for treating rural domestic sewage, whose system eliminated second sedimentation tanks and sludge reflux. The results showed that the average removal rate of COD, NI-13-N, TN and TP were 84. 33% , 97.02% , 80. 18% and 77.34% , respectively; Average concentrations in the effluent was 14.88, 1.06, 9.92 and 0.53 mg/L, respectively. In the effluent of submerged biofilm, the sludge e^ncentration was zero. Consequently, the quality of effluent from stabilization pond was fine, which could meet requirement of the tertiary treated wastewater reuse.
