摘要: 构建了老龄垃圾渗滤液为底物的空气阴极型单室微生物燃料电池，以考察阳极不同改性方式对微生物燃料电池产电性能和对老龄垃圾渗滤液处理效果的影响。结果表明，碳毡阳极经过热处理、浓硝酸、酸性重铬酸钾、混酸的改性后，电池的最大输出功率密度分别提高了104%、241%、51%、181%，COD的去除率变化不大，但氨氮去除率分别增加了22.2%、21.8%、2.3%、47.3%。垃圾渗滤液pH值升高、电导率呈下降趋势。Abstract: An air-cathode single-chamber microbial fuel cells were constructed using the aging landfill leachate as substrate to study the influence of different anode modifications on microbial fuel cell performance in terms of the electricity productivity and the effects on the treatment of aging landfill leachate. After the carbon felt anode modification separately with heating, concentrated nitric acid, acidic potassium dichromate and mixed acid, the maximum output power density of cells increases by 104%, 241%, 51%, and 181%, respectively, and the removal of ammonia increases by 22.2%, 21.8%, 2.3% and 47.3%, respectively, while the removal efficiency of COD is improved less. As the pH value of landfill leachate increases, the conductivity decreases.
