摘    要:构建双室微生物燃料电池(MFC)装置,研究了分别以乙酸钠(NaAc)作单一燃料和乙酸钠+邻苯二甲酸酯(PAEs)作混合燃料条件下,MFC的产电性能及其对邻苯二甲酸酯的去除效果。结果显示,微生物燃料电池对邻苯二甲酸酯类废水的化学需氧量(COD)的总去除率可达89%~94%,对邻苯二甲酸酯的去除率均在70%以上。以2 g·L-1 NaAc+10 mg·L-1 PAEs作混合燃料时,MFC获得最大(面积)功率密度58.78 mW·m-2,电池内阻213.50 Ω。实验结果表明,MFC能够利用高浓度邻苯二甲酸酯作燃料,在实现高效降解的同时稳定地向外输出电能,这为环境激素类难降解有机物的高效低耗处理提供了一种新的研究思路。

关 键 词:微生物燃料电池   邻苯二甲酸酯   极化曲线   去除率

Abstract:A two-chambered microbial fuel cell was designed,and its capability of electricity production and simultaneous phthalate biodegradation using sodium acetate and sodium acetate+phthalate fuels was examined. The results showed that at the end of the electricity generation cycle,the chemical oxygen demand decreased from 89% to 94%,and the phthalate degradation efficiencies exceeded 70%. When using 2 g·L-1 sodium acetate+10 mg·L-1 phthalate as the fuel,the maximal power density of the fuel cell was 58.78 mW·m-2,and the corresponding inner resistance was 213.50 Ω. These results imply that the designed microbial fuel cell can treat phthalate while generating energy,providing a new method for the bioremediation of environmental hormone-disrupting refractory organic matter.
Keywords:microbial fuel cell  phthalic acid esters  polarization curves  removal rates
