Bioelectrochemical systems (BES) represent an energy-efficient approach for wastewater treatment, but the effluent still requires further treatment for direct discharge or reuse. Integrating membrane filtration in BES can achieve high-quality effluents with additional benefits. Three types of filtration membranes, dynamic membrane, ultrafiltration membrane and forward osmosis membrane that are grouped based on pore size, have been studied for integration in BES. The integration can be accomplished either in an internal or an external configuration. In an internal configuration, membranes can act as a separator between the electrodes, or be immersed in the anode/cathode chamber as a filtration component. The external configuration allows BES and membrane module to be operated independently. Given much progress and interest in the integration of membrane filtration into BES, this paper has reviewed the past studies, described various integration methods, discussed the advantages and limitations of each integration, and presented challenges for future development.
生物电化学系统（BES）是一种节能的废水处理方法，但出水仍需要进一步处理才能直接排放或再利用。在 BES 中集成膜过滤可以实现高质量的出水，并带来额外的好处。三种过滤膜，即动态膜、超滤膜和正向渗透膜，根据孔径大小进行分组，已被研究用于集成到 BES 中。这种集成可以采用内部或外部配置来实现。在内部配置中，膜可以作为电极之间的分隔物，或者作为过滤组件浸入阳极/阴极室中。外部配置允许 BES 和膜组件独立运行。鉴于膜过滤与 BES 集成方面取得了很大的进展和关注，本文回顾了过去的研究，描述了各种集成方法，讨论了每种集成的优点和局限性，并提出了未来发展的挑战。
