摘要
膜生物反应器实质是生物降解与膜分离相互影响、共同作用的过程。污泥浓度与膜通量之间存在一定的相关关系,膜分离对生物性能尤其是细菌活性有着重要的影响,而生物反应器内细菌胞外聚合物、溶解性有机物及微细胶体可能成为形成凝胶层导致通量下降的主要因素。
The membrane bioreactor (MBR) is a kind of synergic process of biodegradation and membrane separation essentially. A certain relationship between sludge concentration and membreane flux exits, membrane separation has important effect on the biological properties, especially on the bacterial activity, and bacterial extracellular polymers, dissolved organic substance and fine colloids may be the main factors which form cake layer and result in the decline of membrane flux.
