Bioelectrochemical systems (BES) are considered efficient and sustainable technologies for bioenergy generation and simultaneously removal/recovery metal (loid)s from soil and wastewater. However, several current challenges of BES-based metal removal and recovery, especially concentrating target metals from complex contaminated wastewater or soil and their economic feasibility of engineering applications. This review summarized the applications of BES-based metal removal and recovery systems from wastewater and contaminated soil and evaluated their performances on electricity generation and metal removal/recovery efficiency. In addition, an in depth review of several key parameters (BES configurations, electrodes, catalysts, metal concentration, pH value, substrate categories, etc.) of BES-based metal removal and recovery was carried out to facilitate a deep understanding of their development and to suggest strategies for scaling up their specific application fields. Finally, the future intervention on multifunctional BES to improve their performances of mental removal and recovery were revealed.
生物电化学系统（BES）被认为是从土壤和废水中生成生物能源和同时去除/回收金属（类）的有效且可持续的技术。然而，基于 BES 的金属去除和回收的一些当前挑战，特别是从复杂污染的废水中浓缩目标金属和从污染的土壤中浓缩目标金属，以及它们在工程应用中的经济可行性。本综述总结了基于 BES 的从废水和污染土壤中去除和回收金属的系统的应用，并评估了它们在发电和金属去除/回收效率方面的性能。此外，还深入审查了基于 BES 的金属去除和回收的几个关键参数（BES 配置、电极、催化剂、金属浓度、pH 值、底物种类等），以促进对其发展的深入了解，并提出在其特定应用领域扩大规模的策略。最后，揭示了多功能 BES 的未来干预措施，以提高其金属去除和回收的性能。
