Abstract

As a current technology that can effectively remove organic carbon compounds and immobilize phosphorus in sediment, sediment microbial fuel cells (SMFCs) can combine sediment remediation with power generation. This review discusses the removal efficiency of SMFCs on organic carbon compounds, including sediment organic matter, antibiotics, oil-contaminated sediments, methane, persistent organic pollutants, and other organic pollutants in sediment, with more comprehensive and targeted summaries, and it also emphasizes the mitigation of phosphorus pollution in water from the perspective of controlling endogenous phosphorus. In this review, the microbial community is used as a starting point to explore more about its roles on phosphorus and organic carbon compounds under SMFCs. Electrode modification, addition of exogenous substances and combinations with other technologies to improve the performance of SMFCs are also reviewed. It is further demonstrated that SMFCs have the prospect of long-term sustainability, but more attention needs to be paid to the study of the mechanism of SMFCs and the continuous improvement of devices for further application in practice.

去除有机碳化合物并固定磷酸盐以控制内部污染：沉积物微生物燃料电池，一项前景看好的技术

沉积物微生物燃料电池（SMFCs）是目前能够有效去除沉积物中有机碳化合物和固定磷的技术，它可以将沉积物修复与发电结合起来。本综述讨论了沉积物微生物燃料电池对有机碳化合物的去除效率，包括沉积物有机质、抗生素、石油污染沉积物、甲烷、持久性有机污染物以及沉积物中的其他有机污染物，总结较为全面且有针对性，并从控制内源磷的角度强调了对水体磷污染的缓解作用。本综述以微生物群落为切入点，进一步探讨微生物群落在 SMFCs 条件下对磷和有机碳化合物的作用。此外，还综述了电极改造、添加外源物质以及与其他技术相结合以提高 SMFC 性能的方法。研究进一步表明，SMFCs 具有长期可持续发展的前景，但需要更加关注 SMFCs 的机理研究和设备的不断改进，以便进一步应用于实践。

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.
