摘　　要：针对我国北方地区某地表水体,通过与传统砂滤和单独超滤工艺对比,研究了粉末炭-膜生物反应器(PAC-MBR)工艺净化低温沉后水的除污染效能。结果表明,PAC-MBR能有效除浊,出水浊度仅为0.10±0.03 NTU;对水中耗氧量和UV_(254)的去除效果较优,但去除效能会受到反应器内粉末活性炭(PAC)吸附饱和程度的严重影响,平均去除效率为34.9%和68.4%;能在一定程度上去除水中NH_3-N,平均去除率为29.8%,但将水中NH_3-N降低至0.5 mg/L以下仍存在较大困难。With the comparison of traditional sand filtration and ultra-filtration,contaminant removal efficiencies of powdered activated carbon-membrane bioreactor（ PAC-MBR） process were investigated for treating low temperature settled water from a surface water in North China. During the study,PAC-MBR process could effectively remove the turbidity,and outflow turbidity was only（ 0. 10 ±0. 03） NTU. Besides,COD（Mn）and UV（254） in settled water could be effectively eliminated by PAC-MBR and the removal efficiencies reached 34. 9% and 68. 4%,respectively. However,the removals of COD（Mn） and UV（254） were seriously impacted by the adsorption saturation degree of powder activated carbon in the reactor. Additionally,PAC-MBR could remove NH3- N in a certain extent with an average removal rate of 29. 8%,but it was still difficult to considerably remove NH3-N and ensure the outflow NH3-N lower than 0. 5 mg / L.
