摘　　要：本文研究了厌氧流化床(AFB)常温处理城市污水的工况,并对反应器运行性能的影响因素进行了分析。结果表明:在环境温度20～30℃条件下,当进水COD浓度平均为400mg/l,HRT6h,容积负荷1.9 kgCOD/m^3·d时,去除率可保持在80％左右。In this paper, the process of treating municipal sewage in a laboratory scale anaerobic fluidized bed reactor is studied, and the factors affecting reactor performance are analysed. The results show that sewage averaging 400 mg/l COD is successfully treated with about 80% COD removal rate of 20～30℃ at volumetric loading rate of 1. 9 kgCOD/m^3·d and 6 hours hydraulic retention time.
