中文摘要：

喹啉和吡啶往往共存于实际废水中,本文通过构双极室MFC,以铁氰化钾为电子受体,对喹啉和吡啶在MFC中的降解以及产电性进行研究.结果表明,MFC的最大输出电压随着葡萄糖浓度的降低而降低,当喹啉和吡啶初始浓度均为500mg·L^-1,葡萄糖浓度分别为1000、500、100mg·L^-1时,最高输出电压逐渐降低,分别为606、537、354mV;最大体积功率密度为18.4、14.4和6.3W.m^-3.当以等浓度500mg·L^-1的喹啉和吡啶作混合燃料时,MFC的内阻超过1250Ω,最大体积功率密度为2.9W.m^-3.周期结束时,COD的去除率达79%以上,喹啉和吡啶均可以完全去除,喹啉的降解速率明显高于吡啶.MFC可以利用喹啉和吡啶作为混合燃料,这为含喹啉和吡啶共存类实际废水的MFC处理提供了理论依据.

英文摘要：

Quinoline and pyridine usually co-exist in practical actual wastewater. A dual-chambered microbial fuel cell （MFC） using ferricyanide as the electron acceptor was constructed to investigate degradation of quinoline and pyridine and power generation. The results showed that the maximum voltages dropped when the glucose concentration was decreased. When the initial concentration of both quinoline and pyridine was 500 mg·L^-1,the maximum voltages were 606,537,354 mV with glucose concentrations of 1000,500 and 100 mg·L^-1,respectively. Correspondingly,the maximal volumetric power densities were 18.4,14.4,6.3 W·m^-3. The internal resistance exceeded 1000 Ω and the maximum power density was 2.9 W·m^-3. COD removal rates exceeded 79%,while quinoline and pyridine were completely degraded at the end of the electrical cycle,and the biodegradation rate of quinoline was higher than that of pyridine. The results demonstrated the feasibility of using quinoline and pyridine as fuel in the MFC and provide a theoretical foundation for treatment of practical wastewater containing quinoline and pyridine.
