RESEARCH PROGRESS ON COUPLING SYSTEMS OF CONSTRUCTED MICROBIAL FUEL CELL(MFC)-A2/O
MFC-A2/O is a new type of bioelectrochemical system,which can convert chemical energy into electricity while degrading organic pollutants in wastewater.It further promotes the implementation of the goal of Synergize the Reduction of Pollution and Carbon Emissions,and has important reference value for the upgrading of sewage treatment systems in the future.Combined with the research of many scholars on the performance of MFC-A2/O systems for nitrogen removal and electricity generation,this paper introduces the working principle of MFC-A2/O,reviews the system structure(electrode material,battery configuration,inoculated microorganisms)and operating parameters(C/N,HRT,external resistance,pH,and other conditions).At the same time,this paper summarizes the current problems and deficiencies of the existing systems,discusses their advantages and development prospects in nitrogen removal and electricity generation performance,and provides a reference for the optimization of the MFC-A2/O system.
