摘　　要：采用生物转笼与活性污泥复合工艺,以中试规模处理某高校校园生活污水。结果表明,在反应时间为5 h,转笼转速0.5r/min左右,转笼反应槽中气水体积比1:1,污泥体积回流比100%时,出水COD平均为26.7mg/L,NH3-N、TN和TP平均质量浓度分别为12.4、15.5、0.67mg/L,COD、NH3-N、TN、TP的平均去除率分别达到90.4%、63.1%、59.8%、58.6%。Piolt tests were conducted to investigate the performance of hybrid rotating biological contactor with drum activity sludge for domestic wastewater.The results suggested that the average concentrations of COD,ammonia,total nitrogen and total phosphorus in effluent were 26.7 mg/L,12.4 mg/L,15.5 mg/Land 0.67 mg/L,respectively;the removal efficiencies of COD,ammonian,total nitrogen and total phosphorus were 90.4%,63.1%,59.8% and 58.6%,respectively;in condition of the hydraulic retention time was 5 h,the cage speed was about 0.5 r/min,the gas water ratio was 1：1,the sludge re-turn ratio was 100%.
