| 摘 要： | 采用一体式膜生物反应器,考察了4种不同膜丝长度(0.3、0.5、0.7和1.0 m)的柱式膜组件在不同曝气量下的临界通量.研究发现:膜组件的长度存在最优值,膜组件的临界通量同时受到膜丝长度和曝气强度两个方面的影响;当膜组件的膜丝长度为0.7 m时,临界通量最高;同时曝气强度越大,膜组件可以达到的临界通量越高.

| Abstract: | The critical flux region of four column membrane modules with different membrane fiber lengths(0.3,0.5,0.7 and 1.0 meter)is studied by using submerged membrane bioreactor under different aeration intensity.The re-sults show that the length of membrane module exists optimal value.The critical flux of membrane modules is influenced by the length of membrane module and aeration intensity.When the membrane fiber length is 0.7 m,the critical flux reaches to maximum.Meanwhile,the critical flux of the membrane mod... |
