摘　　要：厌氧膜生物反应器(AnMBR)是一种集约型污水处理技术,因具有诸多优点而受到国内外学者的广泛关注,但运行过程中产生的膜污染问题是制约AnMBR进一步推广的关键影响因素。微生物电解池(MEC)耦合AnMBR技术是一种具有应用前景的技术,其可通过利用MEC阴极产氢原位冲刷污染物、增强污染物与膜面之间静电斥力的方式缓解AnMBR运行过程中的膜污染问题。基于此,系统综述了MEC-AnMBR耦合技术近年来的研究进展,介绍了MEC-AnMBR反应器的构成及基本原理,总结并分析了耦合系统在污染物去除、膜污染控制及能源回收中的应用情况,最后讨论了MEC-AnMBR耦合技术运行中的重要影响因素,并对未来MEC-AnMBR耦合技术的研究方向进行了展望。Anaerobic membrane bioreactor(AnMBR)is an intensive sewage treatment technology,and has drawn considerable attention worldwide owing to its distinctive advantages.However,the inevitable problem of membrane fouling during operation is a key factor restricting the further promotion of AnMBR.The integration of microbial electrolysis cell(MEC)with AnMBR(MEC-AnMBR)technology has been proved to be a promising technology.In that system,not only the production of hydrogen on cathode of MEC could in situ stripping the pollutants,but also the enhancement of the electrostatic repulsion between the pollutants and the membrane surface could alleviate membrane fouling.Based on this,the advances in research of MEC-AnMBR in recent year were systematically re⁃viewed.Firstly,the configuration and basic principle of MEC-AnMBR were summarized.Then,the MEC-AnMBR performance of pollutants removal,membrane fouling control and energy recovery were reviewed.Finally,the impor⁃tant factors influencing the operation of MEC-AnMBR coupling technology were discussed and the future research direction of MEC-AnMBR technology were proposed.
