循环伏安扫描对微生物燃料电池启动和产电性能的影响
Effect of cyclic voltammetry process on start-up and electricity performance of microbial fuel cells
摘要
Abstract
The start-up process and power generation of microbial fuel cells (MFCs) influence the practical application of MFCs for wastewater treatment. In this paper, we reported a novel way to accelerate the electrochemical active biofilm formation by conducting the cyclic voltammetry (CV) scans on the cell. The MFCs with CV scan of 24 h reduced the start-up time by 71.4% from 420 to 120 h, and increased power density by 21.5% from 31.1 to 37.8W·m?3, comparing to the MFCs started-up with an external resistance of 1000?. The fast growth rate of biomass having dominant electrogenic bacteria under CV scans contributed to the enhancement of MFCs performance. This technology provides a novel approach to short the start-up time and increase the power density of MFCs.关键词
