Performance Study on Microbial Fuel Cell Treating Restaurant Wastewater

Microbial fuel cell is regarded as a new wastewater treatment technology, which has the advantages of high-efficiency, low energy consumption, clean and environmental protection. As a complex biological electrochemical reaction system, many factors will have significant impacts on its performance. Solving the bottleneck problem of microbial fuel cell, operation is the key precondition to promote its practical application. This paper studies the effect of electrolyte and electrode area on the microbial fuel cell for wastewater treatment through experiments, so as to provide the basis for applying microbial fuel cells into an actual wastewater treatment system. The experimental results show that using microbial fuel cells for restaurant wastewater treatment, we can achieve water purification effect in certain, and electrolyte and electrode area are important factors affecting the wastewater treatment performance. By choosing a suitable cathode electrolyte, the sewage treatment performance of the microbial fuel cell can be improved effectively.
