Abstract

Contamination of the subsurface environment poses a serious hazard to the environment and human health. Recently, the bioelectrochemical system (BES) has drawn great attention in soil and groundwater remediation as it does not necessitate the addition of chemicals and exhibits minimal energy consumption to facilitate microbial degradation of pollutants. However, the complexity of the subsurface environment and the design parameters of the BES significantly affect the remediation performance and the current literature on BES primarily concentrates on its application in wastewater treatment, with a lack of summary of that in the subsurface environment. Therefore, the purpose of this review was to provide the current status, challenges, and outlooks of BES in situ treatment of pollutants from soil and groundwater. Firstly, the principles and efficacies of BES in treating the typical pollutants from the subsurface environment were discussed. Secondly, the factors that impact the BES treatment efficiencies, especially soil properties, the distinctive and pivotal factors for BES in situ application, were discussed specifically. Finally, the challenges and outlooks of BES for the in situ remediation of the contaminated soil and groundwater were addressed. BES is a green and sustainable in situ remediation technology and future advancements may necessitate the integration with complementary technologies and innovative system configurations to advance the practical implementation of BES.

污染土壤和地下水的原位生物电化学修复研究进展

地下环境污染对环境和人类健康造成严重危害。近年来，生物电化学系统（bioelectrochemical system， BES）因其不需要添加化学物质，且能耗低，有利于微生物降解污染物而在土壤和地下水修复中受到广泛关注。然而，由于地下环境的复杂性和BES的设计参数对修复性能影响较大，目前关于BES的文献主要集中在其在废水处理中的应用，缺乏对其在地下环境中的应用的总结。因此，本文综述了BES原位处理土壤和地下水污染物的现状、挑战和展望。首先，论述了BES处理典型地下环境污染物的原理和效果。其次，具体讨论了影响BES处理效率的因素，特别是土壤性质，这是BES原位应用的独特和关键因素。最后，指出了BES在土壤和地下水原位修复中面临的挑战和前景。BES是一种绿色和可持续的原位修复技术，未来的发展可能需要与互补技术和创新系统配置的整合，以推进BES的实际实施。

期刊介绍： Environmental Pollution is an international peer-reviewed journal that publishes high-quality research papers and review articles covering all aspects of environmental pollution and its impacts on ecosystems and human health. Subject areas include, but are not limited to: • Sources and occurrences of pollutants that are clearly defined and measured in environmental compartments, food and food-related items, and human bodies; • Interlinks between contaminant exposure and biological, ecological, and human health effects, including those of climate change; • Contaminants of emerging concerns (including but not limited to antibiotic resistant microorganisms or genes, microplastics/nanoplastics, electronic wastes, light, and noise) and/or their biological, ecological, or human health effects; • Laboratory and field studies on the remediation/mitigation of environmental pollution via new techniques and with clear links to biological, ecological, or human health effects; • Modeling of pollution processes, patterns, or trends that is of clear environmental and/or human health interest; • New techniques that measure and examine environmental occurrences, transport, behavior, and effects of pollutants within the environment or the laboratory, provided that they can be clearly used to address problems within regional or global environmental compartments.
