| 摘 要： | 以吉林省四平市某垃圾场渗滤液为燃料, 纯钛板为负载微生物阳极和阴极, 用盐桥转移电子方式组建双室微生物燃料电池(DCMFC). 研究阴极室溶液电子受体质量浓度、 pH值、 温度等因素对输出功率密度、 开路电压、 内阻等电池性能的影响, 并考察了对垃圾渗滤液的处理效果. 实验结果表明, 阴极溶液以1.0 g/L双氧水为电子受体, 在pH=2.5、 ρ(硫酸钠)=0.5 g/L、 温度约为30 ℃的最佳实验条件下, 该微生物燃料电池的输出功率密度达12.074 W/m2, 开路电压为1.13 V, 内阻为76.868 Ω. 经过连续30 d的运行, 垃圾渗滤液化学需氧量(COD)去除率达95%, 表明选择恰当的阴极室溶液能提高微生物燃料电池的产电性能.
