摘要
对比研究空气阴极单室与双室微生物燃料电池(MFC)在去除硫化物及产电性能。当硫化物浓度为100mg/L,共基质葡萄糖浓度为812 mg/L时,单室和双室MFC的最大开路电压分别达897.2 m V和821.7 m V,最大输出功率分别为340.0 m W/m^2和273.8 m W/m^2,库仑效率分别为5.6%和10.7%,单室MFC表现出更好的电能输出,而双室MFC的能量转化效率更高。单室MFC运行72小时后,含硫化物废水中的硫化物去除率为75.4%。含硫化物废水中的有机质也可以得到同步去除,TOC的去除率为17.8%。上述结果表明利用MFC去除硫化物并同步产电是可行的,阴极是系统的主要限制因素。
Comparison of air-cathode single chamber and double chamber Microbial fuel cells(MFCs)for sulfidecontainingwastewater treatment was carried out.It was found that sulfide containing wastewater could be treatedbased on MFC technology with energy recovery.The maximum open circuit voltage of897.2mV and821.7mV,maximum power density of340.0mW/m2and273.8mW/m2,and the coulombic efficiency(CE)of5.6%and10.7%were realized in the single chamber and double chamber MFCs,respectively,with influent sulfide100mg/Land glucose812mg/L.Single chamber MFCs had higher performance in electricity output,but double chamberones had a higher CE.After72hours operation of the single chamber MFCs,sulfide and TOC removal efficienciesreached75.4%and17.8%,respectively.Results indicate the feasibility of sulfide removal in MFCs and the cathoderesistance is recognized as the main limiting factor in the reported system.
