摘　　要：为提高传统微生物燃料电池(MFC)在低温条件下的效率,实现实验装置放大化.本实验将连续搅拌反应系统(CSTR)与双极室微生物燃料电池系统相结合,连续流处理糖蜜废水,并间接回收金属单质,处理模拟电镀废水,考察系统的产电性能和废水处理效果.结果表明,当系统稳定运行后,最高电压及功率密度分别可达到340 m V和58.65 m W·m-2.20 d后,系统COD去除率明显增加,最高COD去除率可达到81%.实验运行10 d后,银离子开始析出,最高去除率可达到90%左右.In order to improve the efficiency of traditional microbial fuel cells （ MFC ） at low temperatures, and scale up the experimental device amplification, this experiment combined a continuous stirred reactor with a two chamber microbial fuel cell to continuously process molasses wastewater and simulated electroplating wastewater, indirectly recovered metals, and investigated electricity production and wastewater treatment effect. The results from the experiment showed that the highest voltage output of 340 mV and the maximum power density of 58. 65 mW·m^-2 were obtained under a stable operating condition. In addition,COD removal rate reached its highest value （81%）after 20 d, and the maximum removal rate（90%） for Ag^＋ was recorded after 10 d.
