| 摘 要： | 自行设计了总体积为10 L升流式微生物燃料电池(UMFC),以铁氰化钾为阴极电子受体,研究不同水力停留时间,回流比和外电阻对UMFC处理模拟废水和产电能力的影响。结果表明,UMFC在无回流、HRT为6 h时的产电效率最佳,得到的最大功率密度为21.4 mW.m-2,COD去除率为22.7%。增加回流后,当体积回流比100%时,最大功率密度提高了12.5%～13.3%,COD去除率提高了37.7%～52.9%。改变外电阻后,发现小电阻有助于提高UMFC对COD的降解能力。

| Abstract: | An upflow microbial fuel cell(UMFC) was designed and was used for wastewater treatment,potassium ferricyanide was used as electron acceptor in the cathode.Hydraulic retention time(HRT),recirculation ratio and external resistance were studied.The results showed that UMFC got its best performance of generating electricity at 6 h of HRT without no recirculation ratio,the maximum power density was 21.4 mW·m-2 and COD remove rate was 22.7%.After applying the recirculation system,the maximum power density was improved by 12.5%～13.3%,COD remove rate was improved by 37.7%～52.9%.Reserch also showed that small external resistance can improve the performance of COD degradation. |
