摘　　要：为改善农村日益严重的水环境问题,根据倒置A^2/O的基本原理,进行了连续流连续生化反应器(continuous-flow continuous biochemical reactor,C-CBR)一体化生物反应器处理农村生活污水的研究。研究结果表明:在平均水温23℃、水力停留时间12.9 h以及混合液回流比400%的运行条件下,原水COD、NH_4^+-N、TN和TP质量浓度分别为242、35、56、4.2 mg/L时,平均去除率分别为74.3%、53.8%、50.1%和60.3%,出水平均质量浓度分别为60.6、15.9、27.1、1.7 mg/L,出水水质满足《城镇污水处理厂污染物排放标准》二级排放标准,经计算运行费用仅为0.55元/t。In order to improve the rural water environment,the continuous-flow continuous biochemical reactor（ C-CBR） integrated bioreactor for the treatment of rural domestic sewage was studied based on the basic of reversed A^2/O process. The results showed that the C-CBR was operated under the condition of average temperature of 23℃,hydraulic retention time of 12.9 h and mixed solution reflux ratio of 400%. The average removal rates of COD,NH4^＋-N,TN and TP were 74.3%, 53.8%, 50.1% and 60.3%,corresponding to the relative influent concentrations of 242,35,56 and 4.2 mg/L,respectively. The average concentrations of effluent were 60.6,15.9,27.1 and 1.7 mg/L,respectively. Effluent quality could meet the secondary standard of ＂ Discharge standard of pollutants for municipal wastewater treatment plant＂. The operating costs was calculated to be merely 0.55 RMB/t.
