Bioelectrochemical approaches offer a simple, effective, and environmentally friendly solution to pollutant remediation. As a versatile technology, although many studies have shown its potential in soil heavy metal(loid) remediation, the mechanism behind this process is not simple or well-reviewed. Thus, in this review we summarized the impacts of the microbial fuel cells (MFCs) on metal (loids) movement and transformation in the soil environment in terms of changes in soil pH, electromigration, and substrate competition between anode-respiring bacteria and the soil microbial community. Furthermore, the progress of MFCs in the fixation/removal of different elements from the soil environment is described. Hence, this review provides critical insight into the use of the MFC for soil metal(loid) bioremediation.
生物电化学方法为污染物修复提供了一种简单、有效和环保的解决方案。作为一种多功能技术，尽管许多研究表明它在土壤重金属修复方面具有潜力，但该过程的机制并不简单，也没有得到很好的综述。因此，在本综述中，我们根据土壤 pH 值、电动迁移和阳极呼吸细菌与土壤微生物群落之间的底物竞争的变化，总结了微生物燃料电池（MFC）对土壤环境中金属（类）迁移和转化的影响。此外，还描述了 MFC 从土壤环境中固定/去除不同元素的进展。因此，本综述为 MFC 在土壤金属（类）生物修复中的应用提供了重要的见解。
