摘　　要：对气提反应器处理生活污水进行了试验研究,探讨了生物膜的形成和水力停留时间及曝气量对中低浓度生活污水处理效果的影响。结果表明：最优条件是在HRT为6h,曝气量为0.6m^3/h,进水COD和NH4^＋-N质量浓度分别为240.2-298.7mg/L和29.1－68.9mg/L条件下,平均COD去除率为83%,NH4^＋-N去除率为95.1%。An experimental study on the domestic wastewater treatment using an airlift reactor was presented in this paper.The formation of biofilm and the effects of hydraulic retention time（HRT） and volumetric gas rate on efficiency of the medium and low concentrations of sewage treatment were studied.The results showed that the average COD and NH4^＋-N removal rates were 83% and 95.1% under the condition of HRT 6 h,volumetric gas rate of 0.6 m3/h and the influent COD and NH4^＋-N concentration of 240.2 - 298.7 mg/L and 29.1 - 68.9 mg/L respectively.
