MBR及其在难降解废水中的应用

膜生物反应器是将高效的膜分离技术与传统活性污泥法相结合的一种新型高效污水处理工艺。在膜生物反应器中,由平板膜及其构件组成的膜组件浸放于曝气池中,将曝气池中的细菌胶团和游离细菌全部保留在曝气池中,既能维持高浓度的活性污泥,污染物去除效率高,又能免去二沉池,保证出水悬浮物接近零的优良出水水质。重点阐述了膜生物反应器及膜生物反应器组件的分类及在难降解废水中的应用研究。

Membrane Bioreactor and Its Application in Treatment of Refractory Wastewater

Membrane Bioreactor（MBR）,that is the new high-performance membrane separation technology combined with the traditional activated sludge method,is a new type of highly efficient sewage treatment process.In the membrane bioreactor,membrane module can maintain bacteria micelles and free bacteria in aeration tank,which not only maintain a high level of activated sludge concentration,pollutant removal efficiency,but also remove the secondary sedimentation tank.In this paper,classification and applications of membrane bioreactors were introduced.
