Performance Study on Microbial Fuel Cell Treating Restaurant Wastewater

摘要

Microbial fuel cell is regarded as a new wastewater treatment technology, which has the advantagesof high-efficiency, low energy consumption, clean and environmental protection. As a complex biologicalelectrochemical 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 itspractical application. This paper studies the effect of electrolyte and electrode area on the microbialfuel cell for wastewater treatment through experiments, so as to provide the basis for applyingmicrobial fuel cells into an actual wastewater treatment system. The experimental results show thatusing microbial fuel cells for restaurant wastewater treatment, we can achieve water purificationeffect in certain, and electrolyte and electrode area are important factors affecting the wastewatertreatment performance. By choosing a suitable cathode electrolyte, the sewage treatment performanceof the microbial fuel cell can be improved effectively.
