底物对微生物燃料电池产电性能的影响
Effects of Substrate on the Electricity Generation Characteristics of Microbial Fuel Cell
摘要
Abstract
A reaction equipment of microbial fuel cell (MFC) with“H” structure was designed and fabri‐cated .The sludge collected from the aeration tan in Datianwan Sewage Treatment Plant in Jishou was used to inoculate electricigens .The effects of substrate species and concentration on the electricity gener‐ation of M FC in view of start‐up time ,time for obtaining stable open circuit voltage ,electromotive force , internal resistance and power density were investigated .Experimental results showed that the substrate species and concentration greatly influenced the electricity generation of M FC probably due to their difference in structure .It was found that the white dextrin‐fed MFC could be started up in shorter time with smaller internal resistance ,smaller electromotive force and smaller power density .Under the same conditions ,the soluble starch‐fed MFC had larger electromotive force ,larger power density ,bigger inter‐nal resistance and longer time to be started‐up .The results also indicated that an increase in the substrate concentration increased the time for reaching constant OCV at low concentration of 2~6 g/L for soluble starch and 2~8 g/L for white dextrin .While an opposite trend was observed at high concentration of 8~20 g/L for soluble starch and 10~20 g/L for white dextrin attributed to the substrate inhibition effect .关键词
