摘要
运行耗能低和出水水质好是未来废水处理技术的发展趋势。生物电化学辅助膜生物反应器(bioelectrochemistry-assisted membrane bioreactor,BEMBR)耦合了膜生物反应器和微生物燃料电池两种新型水处理技术,取长补短,有效降低了膜污染速率和提高了出水水质,具有良好的应用前景。本文根据膜组件在BEMBR中的功能综述3种典型反应器构型的优势与不足;从COD去除路径和总氮脱除机制分析了BEMBR污泥减量、能耗削减和污染物去除提升的机理;从物理机制、化学机制及生物机制详细阐述了BEMBR抗膜污染机理。最后,针对目前BEMBR存在的局限,从产电性能、污染物去除效果、膜污染控制机理和微生物种群及代谢等方面提出展望,为加快BEMBR工程化应用提供理论参考。
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.
