Strategies for enhancing performance of anaerobic digestion (AD) process has been widely studied. The bioelectrochemical system (BES), including microbial fuel cell, microbial electrolysis cell (MEC), microbial desalination cell, and microbial electrosynthesis, had been proposed to integrate with AD for performance enhancement. This mini-review summarizes the current researches that integrated AD with BES to enhance the performance of the former. The working principles of BES were introduced. The integrated configurations of AD-BES as well as the associated applications were summarized. The statistics analysis for AD-MEC performances reported in literature were then performed to confirm the effects of reactor size and applied voltage on the methane productivity and enhancement. The challenges and prospects of the integrated AD-BES were delineated, and the potential scenarios of applying integrated AD-BES in field were discussed.
提高厌氧消化(AD)过程性能的策略已得到广泛研究。生物电化学系统(BES),包括微生物燃料电池、微生物电解池(MEC)、微生物脱盐池和微生物电合成,已被提议与AD集成以提高性能。本综述总结了目前将AD与BES集成以提高前者性能的研究。介绍了BES的工作原理。总结了AD-BES的集成配置及其相关应用。然后对文献中报道的AD-MEC性能进行统计分析,以确认反应器尺寸和施加电压对甲烷生产率和提高效果的影响。阐述了集成AD-BES面临的挑战和前景,并讨论了在现场应用集成AD-BES的潜在场景。
