厌氧膜生物反应器膜污染及其控制研究进展

Research Progress on Membrane Fouling and its Control in Anaerobic Membrane Bioreactor

厌氧膜生物反应器(Anaerobic Membrane Bioreactor,AnMBR)是一种高效的厌氧生物处理系统,因其具有高容积负荷、低占地面积、优良的出水水质等优点受到了广泛关注。然而膜污染会导致膜组件性能下降,进而增加运行中能量消耗并降低膜组件寿命,是影响An MBR经济、技术可行性的关键因素。综述了An MBR的发展进程,分析了膜污染的影响因素,归纳总结了膜污染控制手段,并在此基础上展望了An MBR的未来研究方向,以期为An MBR的基础研究与推广应用提供理论指导与技术支撑。

As an efficient anaerobic biological treatment system,anaerobic membrane bioreactor(AnMBR)has been widely concerned because of its high volume load,small occupied area,excellent quality effluent and so on.However,membrane fouling will lead to a decline in the performance of membrane components,while increasing energy consumption in operation and reducing life span of the membrane components.Hence,it becomes the critical factor affecting the economic and technical feasibility of the AnMBR.In this study,the development history of AnMBR,the influences and controlling measures of membrane fouling were outlined.Finally,future research directions were put forward to provide theoretical direction and technical support for the fundamental research and technical support of AnMBR.
