摘　　要：应用动态膜原理,以0.1mm孔径的普通筛绢代替固定膜材料构成一体式动态膜-生物反应器(DMBR)处理实际化粪池污水。HRT=5h,膜通量J=18L/(m2·h)。动态膜生物反应器对COD和NH4+-N的平均去除率分别达到了65.3%和68.2%,同时还对动态膜的通透性进行了研究。Instead of static membrane such as micro-filtration membrane or ultra-filtration membrane,the dynamic membrane made of 0.1mm Dacron mesh was utilized to develop a submerged dynamic membrane bioreactor(DMBR).The DMBR was used for treatment of nightsoil at HRT 5h and membrane flux 18L/m2.h.The removal efficiency of COD and NH4+-N in the DMBR was averaged respectively at 65.3% and 68.2%.The filtration capability of the dynamic bio-membrane was also studied.
