摘　　要：分别利用筛绢和钢丝网作为自生动态膜生物反应器的基材并进行了处理城市污水的中试研究。结果表明,钢丝网组件和筛绢组件的出水水质相差不大,出水COD分别为57.5mg/L和50.4mg/L,NH4+-N分别为1.39mg/L和2.84mg/L;在运行了25min后出水浊度可降至5NTU以下并保持稳定;出水SS接近于零。钢丝网组件的平均通量为30.3L/(m2.h),筛绢组件的平均通量为51.9L/(m2.h),后者比前者高71%,但钢丝网的强度明显高于筛绢。In the pilot-scale study on treatment of municipal wastewater, steel wire netting and bolting cloth were respectively served as supporting materials of self-forming dynamic membrane bioreactor. No obvious difference is found between the effluents of two modules with steel wire netting and bolting cloth. The effluent COD concentrations are 57.5 mg/L and 50.4 mg/L respectively, and the ammonia nitrogen concentrations are 1.39 mg/L and 2.84 mg/L respectively. The effluent turbidity is below 5 NTU after running for 25 min and the SS is approximately zero. The average fluxes of modules with steel wire netting and bolting cloth are 30.3 L/（m^2 · h） and 51.9 L/（m^2· h） respectively, the latter being 71% higher than that of the former. The strength of steel wire netting apparently surpasses that of bolting cloth.
