摘要
膜污染是浸没式膜生物反应器(SMBR)工艺中普遍存在的问题,是影响SMBR稳定运行的关键因素.从微观和宏观两方面分析了SMBR的膜污染的机理,综述了国内外控制膜污染问题的最新研究进展,包括膜自身性质的改进、膜组件及反应器结构的优化、污泥混合液特性的改善、工艺运行条件的优化及膜清洗技术的发展,在此基础上指出了目前关于膜污染问题研究的不足及未来的主要发展方向.
Membrane fouling exits generally in submerged membrane bioreactor and it is the key factor to the steady running of the SMBR.The fouling mechanisms of submerged membrane bioreactor are analyzed from both microcosmic and macroscopical aspects in this paper.And the latest research progress on membrane fouling at home and abroad is summarized,including modifying membrane material and characteristic of suspension;optimizing membrane module and configuration of reactor;meliorating operation parameters and membrane cleaning methods.In addition,the faultiness of recent research and suggestions for the further study were given.
