Conventional wastewater treatment consumes a large amount of money worldwide for removal of pollutants prior to its discharge into water body or facilitating reuse. Decreasing energy expenditure during wastewater treatment and rather recovering some value-added products while treating wastewater is an important goal for researchers. Microbial fuel cells (MFCs) are representative bioelectrochemical systems, which offer energy-efficient wastewater treatment. MFCs convert chemical energy of organic matter into electrical energy by using biocatalytic activities. Although MFCs are not truly commercialized, they have potential to make energy-gaining wastewater treatment technologies and represent their capabilities successfully. Over the last decade, MFCs have developed remarkably in almost every dimension including wastewater treatment capabilities, power output, and cost optimization; however, its architectural design is an important consideration for scaling up. Here, we review various architectural advancements and technology up-gradation MFCs have experienced during its journey, to take this technology step forward for commercialization.
传统的废水处理在排放到水体或促进再利用之前，需要在全球范围内花费大量的资金来去除污染物。在处理废水的同时减少能源消耗，而不是回收一些高附加值的产品，这是研究人员的一个重要目标。微生物燃料电池（MFC）是一种具有代表性的生物电化学系统，它提供了节能的废水处理方法。MFC 通过利用生物催化活性将有机物的化学能转化为电能。尽管 MFC 尚未真正商业化，但它们具有成为节能型废水处理技术的潜力，并成功地展示了其能力。在过去的十年中，MFC 在几乎所有方面都取得了显著的发展，包括废水处理能力、功率输出和成本优化；然而，其架构设计是扩大规模的一个重要考虑因素。在这里，我们回顾了 MFC 在其发展过程中经历的各种架构进步和技术升级，以期将这项技术推向商业化。
