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 %K 生物处理 %K 一体化反应器 %K C-CBR %K 农村生活污水 %K 脱氮除磷 %K < %K br> %K C-CBR %K integrated reactor %K biological treatment %K nitrogen and phosphorus removal %K rural domestic sewage %U http://gxbwk.njournal.sdu.edu.cn/CN/10.6040/j.issn.1672-3961.0.2017.452
