Research Progress in Denitrification of Microbial Fuel Cells
The energy scarcity forces people to seek various renewable resources and forms of sustainable green energy technologies.Microbial fuel cells(MFCs),as an environment-friendly energy technology,can effectively reduce the emission of environmental pollutants while coverting biomass into electricity,and show great development potentials.In recent years,the use of MFCs to treat nitrogen-containing wastewater has received widespread attention,which not only can remove the nitrogen pollution from water and wastewater,but also can recover some energy,in order to overcome the high energy consumption defect of traditional treatment methods of nitrogen-containing wastewater.This article provides an overview of the applications and principles of MFCs,the research progress of MFCs in denitrification,and prospects for its future development.
