Abstract

Abstract: Using nitrate solution as cathode electron acceptor,activated sludge flora and denitrifying flora have been inoculated in the cathode chamber,respectively,and two kinds of biocathode microbial fuel cells named A-MFC and D-MFC established,respectively. The denitrification and electricity production of the two kinds of cathode flora MFCs have been investigated,and the degradation process of nitrate has been analyzed by kinetics model. The results show that the difference of cathode flora has influence on the performances of MFC denitrification and electricity production,and denitrifying flora have better affinity ability and greater tolerance degree for nitrate.

Key words: microbial fuel cell, nitrate, activated sludge flora, denitrifying flora

摘要： 以硝酸盐溶液为阴极电子受体，在阴极室分别接种活性污泥菌群和反硝化菌群，分别构建了生物阴极型微生物燃料电池A-MFC和D-MFC。考察两种阴极菌群MFC的脱氮与产电性能，通过动力学模型对硝酸盐降解过程进行分析。结果表明，阴极菌群的不同会对MFC脱氮与产电性能造成影响，反硝化菌群对硝酸盐有更好的亲和能力和更大的耐受程度。
