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.
