摘　　要：利用厌氧附着膜污泥膨胀床(AAFEB)处理寒冷地区小城镇生活污水,并将其出水用于灌溉小白菜,研究厌氧出水用于农业灌溉的可行性。结果表明,AAFEB在10℃以上的条件下能够有效去除生活污水中的COD、粪大肠菌群及重金属等污染物,出水中各污染物浓度均能达到《农田灌溉水质标准》(GB 5084—2005)的要求;与未经处理的生活污水相比,AAFEB出水对小白菜种子发芽的抑制明显减弱,水中的氮、磷等营养物质能够满足小白菜生长所需。The anaerobic attached film expanded bed （AAFEB） process was used to treat domes- tic sewage in cold region, and the treated effluent was used for pakchoi irrigation. The feasibility of using the anaerobic effluent for agricultural irrigation was studied. The results showed that COD, heavy metals, fecal coliform and other pollutants in the sewage could be effectively removed at above 10 ℃, and the ef- fluent quality could meet the requirements in the Standards for Irrigation Water Quality （ GB 5084 - 2005 ）. Compared with the untreated sewage, the inhibition of the effluent of AAFEB process to seed ger- mination was significantly weakened, and nutrients such as nitrogen and phosphorus could meet the needs of the pakchoi growth.
