摘　　要：以三室微生物燃料电池(MFC)为研究对象,采用大肠杆菌(E.coli)作阳极催化剂,比较了在无外加中介体、以中性红(NR)做中介体、以新亚甲基蓝(NMB)做中介体3种情况下的脱氨氮产电性能。结果表明:添加中介体可以提高MFC的开路电压,缩短开路电压达到稳定的时间,以NMB做中介体MFC的开路电压更容易达到稳定值,而以NR做中介体MFC达到的稳定开路电压较前者高。添加中介体能缩短MFC的脱氨氮时间(脱氨氮效率达90%),以NMB做中介体的MFC脱氨氮所需时间更短。以NR做中介体MFC的输出电压更高,但随着时间的延长,以NMB做中介体MFC相比于前者输出电压衰减得慢,稳定性更好。A three chamber microbial fuel cells（MFC） , employing escherichia coliCE. coil） as anode catalyst, was designed. Its electricity generation and ammonia nitrogen removal were in-vestigated in mediator-less, new methylene blue（NMB） as mediator and neutral red（NR） as me-diator conditions. The results show that mediators improved open circuit voltage（VOC） of MFC and reduced the time of reaching steady-state VOC. With NMB mediator, VOC of MFC achieved a stable value more easily. VOC of MFC with NR mdeiator was higher than that of MFC with NMB mdeiator. Meditators reduced denitrification time of MFC （ammonia nitrogen removal efii- ciency of 90%） , besides, denitrification time of MFC with NMB was shorter. VOC was higher with NR as mediator, but VOC had slower attenuation and better stability with NMB as mediater.
