M-cresol wastewater treatment in anaerobic fluidized bed microbial fuel cell and electricity generation performance
摘要
Abstract
Anaerobic fluidized bed single-chamber membrane-less air-cathode microbial fuel cell (AFB-SMFC) was built using m-cresol wastewater as anolyte, using anaerobic activated sludge as inculum, which came from a sewage treatment plant. The properties and kinetics of m-cresol degradation under open circuit and closed circuit operating conditions were investigated. The relationship between the electrochemical action and the microbic degradation ability was discussed. Meanwhile, the effects of external resistance and m-cresol concentration on the degradation of m-cresol and electricity generation performance were studied. The results showed that m-cresol removal rate in the closed-circuit AFB-SMFC was 15.29 mg/(L·h), which was 37% higher than the value (11.18 mg·L-1·h-1)of the open-circuit control. The degradation of m-cresol followed zero-order kinetic equation: -dSt/dt=k. The electricity generation capacity was the best when the external resistance was 5 000 Ω. And the highest removel of the m-cresol was appeared when the external resistance was 1 000 Ω. When the initial concentration of m-cresol was in the ranged of 570 mg/L to 630 mg/L, the electricity generation and m-cresol removal were both excellent, the maximum power density was 324.4 mW/m2 and the m-cresol removal was 96.2%.关键词
