摘　　要：采用重力出水式膜生物反应器,在不同曝气强度下,研究两种不同膜组件的膜通量变化情况,同时找出两组膜组件的经济曝气强度。研究结果表明,膜组件A的经济曝气强度约为50m·3m-·2h-1,平均膜通量为8.91L·m-·2h-1;膜组件B经济曝气强度约为40m·3m-·2h-1,平均膜通量为3.73L·m-2·h-1。长期运行结果表明,膜组件B相对膜组件A可能较快发生膜污染现象。The permeate flux for different membrane moulds in the different aeration intensity was investigated by using membrane bioreactor with gravity flow. The results indicated that the optimization aeration intensity and the average permeate flux for membrane mould A are 50 m^3·m^-2·h^-1 and 8.91 L·m^2·h^-1,the optimization aeration intensity and average permeate flux for membrane mould B are 40 m^3·m^-2·h^-1 and 3.73 L·m^2·h^-1. The mould B appears membrane fouling quickly than the mould A.
