摘　　要：对MBR工艺中的膜组件结构形式进行了优化设计,提出两种优化设计结构(A和B),并通过试验运行证实了膜组件结构形式的改进,对膜通量的维持有促进作用。试验结果还表明,稳定运行时,改进后的膜组件形式既能缓解膜通量的衰减,又能得到较好的出水水质,其中COD的平均去除率在95.5%以上;TN的平均去除率在56.7%以上;浊度的平均去除率在98.2%以上;TP的平均去除率虽波动较大,但B种形式的膜组件效果略好于对照组件和A种形式的膜组件。同时,在小试试验的基础上提出进一步优化的方案。The optimum design of membrane module structures in membrane bio-reactor is studied and two optimum designs of membrane module structure(A and B)are presented.The tests show that the improvement of membrane structure can promote the maintenance of membrane flux when the reac-tor is stable,and they also indicate that the improved membrane structure can not only lighten the attenuation of membrane flux,but also get better quality of treated water.The average removal rate of COD is above95.5%,TN above56.7%and turbidity above98.2%.The average removal rate of TP fluctuates largely.The results of B are just slightly better than those of A.At the same time,the fur-ther optimization plan is presented.
