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.

Abstract:

The doublechamber microbial fuel cell (DCMFC) with landfill leachate from some refuse dump of Siping City of Jilin Province as fuel was designed in the  system with the bacteria in the titanium anode chamber separated from the titanium cathode chamber by a salt bridge. The effects of cathode chamber solution parameters on the electricity generation performance of DCMFC were
 researched. The results show that the DCMFC output power density is 12.074 W/m2, opencircuit voltage is 1.13 V, internal resistance is 76.868 Ω under cathode chamber solution optimum conditions of 30 ℃, 1.0 g/L  H2O2, pH=2.5, and 0.5 g/L  Na2SO4. After the DCMFC was continuously running for 30 days, the COD removal rate of landfill leachate reached to 95%, the adjust of cathode chamber operational parameters can improve the microbial fuel cell electricit generation.

Key words: microbial fuel cells; landfill leachate; , output power density; opencircuit volt
