Abstract: Microbial fuel cell (MFC) recently achieved active energy wastewater treatment at the pilot stage. Despite these achievements, whether all wastewater contains enough energy, and if so, MFC can capture sufficient energy to offset the electrical energy requirements of the wastewater treatment process There is still limited understanding as to whether or not. Currently, there is no tool or method available to determine whether MFC can be a priori energy neutral. In order to solve this problem, we derive a simple relationship by setting the electric energy demand of the wastewater treatment facility equal to the net energy production of MFC and the resulting formula is the minimum chemistry required to achieve energy Represents oxygen demand (COD) removal. - Neutral treatment. The resulting equation is simply a function of electrical energy requirements, coulombic efficiency, and battery voltage.

Microbial fuel cells (MFCs) are becoming promising technologies for treating wastewater. Please check the potential energy conversion efficiency. Review and evaluation of energy recovery (W / m 3 reactor) Several data related to potato treatment wastewater and hospital wastewater have recently been reported. Finally, we model a series of process configurations that MFC can use to process wastewater. Overall, MFC technology is still facing major challenges, especially in terms of chemical oxygen demand (COD) removal efficiency.

The new anaerobic treatment technology is a microbial fuel cell (MFC) that can process wastewater and generate electricity at the same time. Over the past decade, MFC has done extensive research in the laboratory, but so far only a few pilot scale (> 10 L) bioelectrochemical systems have been established and up to various degrees It has been tested. Succeeded. Recent experimental studies have shown that MFC can be self-sufficient as energy captured from MFC can be used to power supply and / or recirculation pumps.
