摘要
以剩余污泥为阳极底物,以模拟中药废水为基质,以Ag^+及Cr(VI)为阴极液,构建微生物燃料电池系统,研究了该MFC系统的产电性能、金属离子处理效果及系统的去污能力。以Cr(VI)和Ag^+两种不同的金属离子作为阴极液,以Ag^+作为阴极电子受体,稳定电压23 m V,CE(Ag+)=8.17%,Ag^+的最终去除率为58.7%,COD去除率为43.47%;以Cr(VI)作为阴极受体稳定电压在10.5 m V左右,CE(Cr6+)=6.06%,Cr(VI)的最终去除率为49.2%,COD去除率为49.26%。
The study used excess sludge as anode,herbal medicine wastewater as substrate,and Ag＋or Cr（ VI） as cathode to construct microbial fuel cell. Characteristics of electricity generations,the treatment of metal ions and the decontamination ability were investigated. When Ag＋was the catholyte,the generate voltage could be 23 m V and CE（ Ag~＋） was 8. 17 %and removal rate of Ag~＋was 58. 7 % and the removal rate of COD was 43. 47 %. When Cr（ VI） was the catholyte,the generate voltage could be 10. 5 m V and CE（ Cr6 ＋） was 6. 06 % and removal rate of Cr（ VI） was 49. 2% and the removal rate of COD was 49. 26 %.
