摘要
采用SPSS分析软件,考察了双室微生物燃料电池(MFC)、单室MFC运行过程中,温度、pH与产电性能的相关关系。结果表明,碳纸双室MFC的日均电压与温度、阳极pH均未呈现显著相关关系,而与阴极pH呈极显著相关关系,产电的决定性因素为阴极反应;石墨毡/碳纸双室MFC日均电压与温度未呈现显著相关关系,而与阳极pH、阴极pH均呈极显著相关关系,产电的决定性因素为pH;单室MFC的产电性能受温度的影响较大,而pH对其影响不显著,对于单室MFC的运行调控应主要从温度入手。
The double and single-chambered microbial fuel cell （MFC） with anaerobic sludge as seeding sludge and sodium acetate （NaAc） as medium were established, and the relationship between voltage and temperature, pH of double and single-chambered MFC was analyzed by SPSS package. In double-chambered MFC, the maximal voltage was significant correlated with anode and cathode pH, but no significant correlations were found between temperature and the maximal voltage. Therefore, it could be concluded that pH had a dominant effect on performance of doublechambered MFC and the influence of temperature was relatively small. In single-chambered MFC, the different conclusions was drew that the performance of single-chambered MFC was more influenced by temperature than by pH, so the temperature should be regulated during the operation to ensure the performance of single-chambered MFC.
