摘　　要：介绍无泡曝气膜生物反应器的理论,对传统膜生物反应器进行改进,同时对传统型膜生物反应器和无泡曝气膜生物反应器处理麻脱胶废水进行比较,得出无泡曝气膜生物反应器对COD和NH3-N的处理效果比传统膜生物反应器分别提高4%和2%。采用无泡曝气作为反冲洗气体,不但提高膜生物反应器中溶解氧量,而且氧利用率也得到提高,且能量消耗也有所降低。Through introducing the principle of bubbleless aerated membrane bioreactor, the traditional membrane bioreactor was improved. It could be obtained that the removal efficiency of COD and NH3 - N in bubbleless aerated membrane bioreactor increased 4% and 2% than that in traditional membrane bioreactor, respectively. Adopting bubbleless aeration as reflushing air which not only increased DO in the MBR, but also advanced the oxygen utilization, and the energy consumption decreased as well.
