摘要
以厌氧污泥作为接种菌源构建双室微生物燃料电池,以1000mg/L葡萄糖自配水为有机燃料,分别以浓度为50mmol/L,pH值为7的铁氰化钾和高锰酸钾为阴极电子受体进行比较。结果显示:铁氰化钾为阴极电子受体时,电池的最大开路电压可达779mV,最大输出功率密度为22.68mW/m^2,电池的内阻为1039Ω;高锰酸钾为阴极电子受体时,电池的最大开路电压可达800mV,最大输出功率密度为41.67mW/m^2,电池的内阻为596.69Ω。可见高锰酸钾是一种理想的电子受体,能够提高MFC产电性能。
With anaerobic sludge as inoculum source to construct double chamber microbial fuel cell, 1000 mg/L glucose water as organic fuel, potassium ferricyanide and Potassium Permanganate were comparedas cathode electron acceptorat the concentration of 50 mmol/L, pH value of 7. The conclusion is that when the potassium ferricyanideis cathode electron acceptor, the maximum open circuit voltage is up to 779 mV battery, the maximum output power density is 22.68 mW/m^2, the internal resistance of the battery is 1039. When Potassium Permanganate is cathode electron acceptor, the maximum open circuit voltage is up to 800 mV battery, the maximum output power density is 41.67 mW/m^2, the internal resistance of the battery is596.69. Therefore, Potassium Permanganate is an ideal electron acceptor,it can improve the electrical properties of MFC.
