膜生物反应器(MBR)相比于传统活性污泥法具有出水水质好、设备占地面积小、剩余污泥产率低和便于自动控制等诸多优点,在污水处理和回用方面极具发展前景。然而膜污染是制约MBR广泛应用的最大障碍。文章着眼于总结MBR中膜污染机理和控制的研究新进展。介绍了MBR中膜污染的分类、污染机理和膜污染影响因素的研究概况,在此基础上,综述了MBR膜污染控制方法方面的进展,并对MBR中的膜污染机理和控制的研究发展方向做了展望。
Membrane bioreactor(MBR) technology with advantages of improved effluent quality,small footprint,reduced sludge production and automated control over conventional activated sludge process,is viewed as a promising solution for wastewater treatment and reuse.However membrane fouling remains a major issue hindering its wide application.The paper aims to summary the advances on the mechanism and control of membrane fouling in MBR system.The research progress in membrane fouling classification,mechanism and factors affecting membrane fouling were firstly introduced.Accordingly advances on membrane fouling control were reviewed,based on which the development tendencies in the field were also discussed.
