Abstract

Abstract:

Low energy consumption and good effluent quality are the development trend of wastewater treatment technology in the future. In order to accomplish this，a bioelectrochemistry-assisted membrane bioreactor (BEMBR) is developed by combining the membrane bioreactor with the microbial fuel cells. Taking advantages of these two bio-technologies，BEMBR has the merits of slow membrane fouling and good effluent quality for engineering applications. According to the role of membrane modules in BEMBR, three typical reactor configurations are discussed on term of their superiority and weakness. For pollutants removal, the COD-removing pathways and nitrogen-removing mechanisms are analyzed, which account for sludge reduction, energy reduction, and improvement of pollutants removal. Then, the membrane fouling mitigation mechanisms of BEMBR are thoroughly explored from the physical, chemical and biological perspectives. Lastly, this review proposes the research directions of BEMBR about the electricity generation, pollutants removal, membrane fouling control mechanisms, and microbial population and metabolism, which will provide more theoretical basis for future applications of BEMBR.
