Microbial electrolysis cell (MEC) is an anaerobic biological process for the conversion of organics in wastewater into renewable energy in the form of hydrogen or methane. However, MEC cannot be used as a standalone technology for urban wastewater treatment, and post-treatment or integrated processes are required to meet water reuse and discharge limits. Recent advances in material science and the discovery of new microorganisms capable of extracellular electron transfer to the electrodes have widened the integration opportunities of MEC in mainstream and side-stream urban wastewater treatment. This review addresses recent developments in the integration of MEC with other processes such as membrane filtration, anaerobic ammonium oxidation and anaerobic digestion, as well as discusses current challenges and new integration opportunities.
微生物电解池（MEC）是一种厌氧生物过程，可将废水中的有机物转化为可再生能源，形式为氢气或甲烷。然而，MEC 不能单独作为城市废水处理技术使用，需要进行后处理或集成工艺，以满足水回用和排放限制。最近材料科学的进展和能够向电极进行细胞外电子转移的新微生物的发现，拓宽了 MEC 在主流和侧流城市废水处理中的集成机会。本文综述了 MEC 与膜过滤、厌氧氨氧化和厌氧消化等其他工艺的集成的最新进展，并讨论了当前的挑战和新的集成机会。
