摘　　要：目前对微生物燃料电池(MFC)的研究主要侧重于产电能力的研究,为了能够进一步提高效率,使实验装置放大化,利用CSTR连续搅拌反应系统原理与双极室微生物燃料电池MFC系统原理相结合,连续流处理糖蜜废水,并间接回收金属单质,考察系统的产电性能和废水处理效果。当系统稳定运行后,最高电压及功率密度分别可达到340mV和58.65mW·m^-2,最高COD去除率可达到81%,银离子的去除率也可达到90%左右。At present, the research on microbial fuel cell ( MFC) mainly focuses on the study of the power production capacity. In order to further improve the efficiency, make the experimental device magnify, use the principle of CSTR continuous agitation system and the principle of MFC system of the bipolar chamber microbial fuel cell, the continuous flow treatment of molasses wastewater, and the indirect process. The metal quality was recovered and the electricity generation performance and wastewater treatment effect of the system were investigated. When the system runs steadily, the maximum voltage and power density can reach 340 mV and 5& 65 mW · m^-2 respectively. The maximum COD removal rate can reach 81 %, and the removal rate of silver ions can reach bout 90%.
