Abstract:

The constructed wetland-microbial fuel cell coupling system is a novel bioelectrochemical process that combines constructed wetland and microbial fuel cell. In this system, constructed wetlands provide the required redox gradients and chemical energy for microbial fuel cells, while microbial fuel cells can improve the processing efficiency of constructed wetlands and recover energy through generating electricity. At present, the research focuses on water treatment. In this paper, combined with the development of constructed wetland-microbial fuel cell coupling system in recent years, the research status of the constructed wetland-microbial fuel cell coupling system is reviewed from two aspects: system construction and system performance. The factors that matter much include the components of the system (wetland plants, electrode materials, matrix materials and microorganisms) and system operating parameters (organic load and wastewater composition, hydraulic retention time, dissolved oxygen and water inflow). Finally, this paper puts forward the main problems that need to be solved in the constructed wetland-microbial fuel cell coupling system. The problems include improving the coulomb efficiency of the system, further reducing the construction cost, improving the comprehensive performance of system decontamination and electricity production, and finally realizing the industrialization of the system.

Key words: microbial fuel cell, constructed wetland, electrochemistry, recovery, water treatment, electricity production
