Abstract

With the rapid development of industrialization and urbanization, wastewater discharge has increased significantly, posing a serious challenge to the environment and human health. Traditional wastewater treatment methods often face the problems of high treatment cost, large energy consumption and sludge generation. Microbial fuel cells show remarkable environmental friendliness in wastewater treatment. Compared to traditional methods, microbial fuel cells reduce the use of chemical agents and reduce the production of sludge, thus reducing the pressure of subsequent treatment. At the same time, the electricity generated by the microbial fuel cell can supply the operation of the sewage treatment plant itself, further reducing the dependence on external energy sources. Microbial fuel cell also has high stability and adaptability. Microbial communities can self-repair and reproduce in the wastewater treatment process, maintaining a high treatment efficiency. At the same time, by optimizing electrode materials, microbial species and reaction conditions and other factors, the electric generation performance of microbial fuel cells and wastewater treatment effect can be further improved. Microbial fuel cells have broad application prospects in wastewater treatment. It can not only realize the efficient treatment of wastewater and the production of clean energy, but also has the advantages of environmental friendliness and economic feasibility.
