【摘要】：膜生物反应器(MBR)因其具有出水水质优质稳定、剩余污泥少、运行控制灵活等优点,被广泛应用于国内外水处理领域。然而,膜生物污染是制约MBR进一步发展的瓶颈问题,一些研究者已尝试多种方法控制膜的生物污染,但都有其各自的缺陷。其中,通过利用微生物自身代谢来控制膜生物污染的生物控制策略,正得到人们越来越多的关注。回顾了生物污染的形成过程,总结了传统物理化学控制方法的缺点,同时介绍了近年来国内外膜生物污染的生物控制方法研究进展,包括酶降解法、群体感应抑制法、能量解耦法、一氧化氮诱导法、噬菌体法和D-氨基酸法。最后根据目前国内外的研究现状,展望了生物控制方法未来的研究前景。
[Abstract]:Membrane bioreactor (MBR) has been widely used in water treatment field at home and abroad because of its advantages of high quality and stable effluent quality, less excess sludge, flexible operation control and so on. However, membrane biological pollution is a bottleneck problem that restricts the further development of MBR. Some researchers have tried various methods to control membrane biological pollution, but all of them have their own defects. Among them, more and more attention has been paid to the biological control strategy of controlling membrane biological pollution by using microorganism's own metabolism. This paper reviews the formation process of biological pollution, summarizes the shortcomings of traditional physical and chemical control methods, and introduces the research progress of biological control methods of membrane biological pollution at home and abroad in recent years, including enzymatic degradation method and group induction inhibition method. Energy decoupling method, nitric oxide induction method, phage assay and D-amino acid method. Finally, according to the current research situation at home and abroad, the prospect of biological control methods in the future is prospected.
