摘要
膜生物反应器(MBR)技术作为"21世纪最具前景的污水处理技术",具有出水水质优异、操作运行简单、污泥产率低、占地面积小等特点,其应用日趋广泛,但由于膜污染导致的膜通量下降、增加运行费用等问题,已成为MBR技术推广运用的主要制约因素之一。基于对膜污染成因、分类、影响因素的分析,综述了膜污染控制的各类研究进展,并对膜污染控制及MBR的运用做出展望。
As the 21st century′s most promising wastewater treatment technology,with advantages of improved effluent quality,simple operation,small footprint and reduced sludge production,membrane bioreactor(MBR)technology is increasingly wide. However,the decline of membrane flux and cost's increasing which were led by membrane pollution,have become one of the main factors restricting the application of membrane bioreactor. Based on analysis of membrane pollution′s cause,kinds and influence factor,the paper summarizes the research progress of membrane pollution control and also predicts the application of membrane pollution control and membrane bioreactor.
