摘　　要：采用厌氧膜生物反应器（AnMBR）在常温（24—29℃）下处理实际生活污水，考察了该系统在不同HRT下的处理效能及厌氧污泥的特性。结果表明，AnMBR在常温下对生活污水有良好的处理效果，对COD的去除率为70．3％-86．3％；当HRT从48h缩短至24h和12h时，对COD的平均去除率略有下降。对污泥特性的分析显示，在较短HRT下，虽然污泥颗粒粒径减小，产甲烷活性降低，但由于污泥量的增加，系统对生活污水的处理效果并未受到显著影响。An anaerobic membrane bioreactor （AnMBR） was used for treatment of real domestic sewage at ambient temperatures of 24 to 29 ℃. The treatment efficiency and anaerobic sludge characteristics of the AnMBR under the different hydraulic retention time （HRT） were investigated. The results indicated that the COD removal rate of 70.3% to 86.3% was achieved in the AnMBR, suggesting that the AnMBR system was effective in treating the domestic sewage at ambient temperature. When the HRT was shortened from 48 h to 24 h and 12 h, the average COD removal rate slightly decreased. The analytic resuits of sludge characteristics revealed that although the sludge particle size and the methanogenic activity decreased under the shorter HRT, the biological treatment efficiency of the domestic sewage in the An- MBR was not significantly affected due to the increase in the amount of sludge.
