摘　　要：研究一体化连续流间歇曝气膜生物反应器(IMBR)处理低C/N城市污水的工艺效能。试验结果表明:反应器在曝气2 h、搅拌2 h的运行模式下,对COD、NH4+-N、TN和SS的平均去除率分别达到了87%,83.4%,75.4%和97.81%,各出水质量浓度平均值分别为17.5,4.59,7.63和2 mg/L,出水水质达到了GB/T18920-2002《城市污水再生利用城市杂用水水质》标准。The integrated intermittent-aeration membrane biological reactor （IMBR） was investigated to treat the low C/N ratio urban sewage. Pollutants removal efficiency of IMBR under the condition of aeration 2 h and agitation 2 h were researched. The results showed that the average removal rates of COD, NH4＋ -N, TN and SS were 87%, 83.4%, 75.4% and 97.81% respectively. The average concentrations of COD, NI~~ -N, TN and SS in the effluent of IMBR system were 17.5, 4.59, 7.63 and 2 mg/L respectively. The effluent quality of IMBR could meet the standard of the requirement reclaimed water quality criterion （GB/T18920- 2002）.
