  • 摘要: 基于双室微生物燃料电池(microbial fuel cell, MFC),针对阴极分别接种活性污泥(A-MFC)和反硝化细菌(D-MFC),研究其产电情况和硝酸盐废水去除效果。结果表明,在产电的同时都可有效去除废水中的硝酸盐污染物。在外接电阻100 Ω的情况下,2种MFC均具有良好的产电性能,A-MFC和D-MFC达到的最大输出电压分别为119.6 mV和117.2 mV,最大功率密度分别为23.40 mW/m2和26.63 mW/m2;同时两者在阴极室的平均反硝化速率分别为1.86 mg/(L·d)和2.19 mg/(L·d),阳极室的平均COD去除率分别为81.9%和82.4%。另外,通过扫描电镜观察可知,A-MFC和D-MFC阴极碳布表面形貌存在差异,并且阳极与阴极碳布表面形貌差异显著。
    Abstract: Based on double-chamber microbial fuel cell(MFC), activated sludge (hereinafter referred to as A-MFC) and denitrifying bacteria (hereinafter referred to as D-MFC) were inoculated in the cathode respectively. The performance of their power generation and nitrate removal from the wastewater were investigated. The results show that each of them can generate electricity and denitrify the nitrate pollutants simultaneously. Under 100 Ω external resistance, both A-MFC and D-MFC have good power generation performance. The maximum output voltage and power density of A-MFC are 119.6 mV and 23.40 mW/m2, respectively, and those of D-MFC are 117.2 mV and 26.63 mW/m2, respectively. The average denitrifying rate in the cathode and COD removal rate in the anode of A-MFC are 1.86 mg/(L·d) and 81.9%, respectively, and those of D-MFC are 2.19 mg/(L·d) and 82.4%, respectively. In addition, the SEM images indicate that differences exist in surface morphology of carbon cloth not only in A-MFC and D-MFC cathode, but greatly in the anode and cathode.
