Biological cathode microbial fuel cell can reduce harmful heavy metals in heavy metal wastewater into simple substances or low toxic and low valent substances,which has the advantages of high efficiency,low toxicity and no pollution,and is expected to provide a new way for bioremediation of heavy metal contaminated wastewater.In this paper,the microbial fuel cell was briefly introduced,the synergistic effect of the electrochemical process on the biological cathode and the microorganism in the process of reducing heavy metal ions was summarized,and the recent research trends of biocathode microbial fuel cells were discussed,and the future enhancement of heavy metal wastewater treatment efficiency and practical application of biocathode microbial fuel cells were prospected.
