| 摘 要： | 对利用单室空气阴极微生物燃料电池(MFC)降解水中红霉素(ERY)进行了研究。结果表明,ERY的加入使MFC阳极上的产电菌活性受到抑制,ERY浓度越大,对产电菌抑制性越强。当ERY质量浓度为30 mg/L时,MFC最大功率密度为400 mW/m^2,ERY降解率为(83.21±1.4)%,COD去除率为(84.91±2.1)%。加入ERY后,阳极微生物群落发生改变,但主要物种相同且数量较大,厚壁菌门(Firmicutes)、放线菌门(Actinobacteria)和变形菌门(Proteobacteria)这3类产电菌门为微生物燃料电池的性能发挥了重要作用。

| Abstract: | The degradation of erythromycin(ERY)in water was studied using a single-chamber air cathode microbial fuel cell(MFC).The experimental results showed that ERY inhibited the activity of the electrogenic bacteria on the MFC anodes.The higher the ERY concentration,the stronger the inhibition of the electrogenic bacteria.When the ERY concentration was 30 mg/L,the maximum power density of MFC was 400 mW/m^2,the degradation rate of ERY was(83.21±1.4)%,and the removal rate of COD was(84.91±2.1)%,respectively.After adding ERY,the anode microbial community evolved,while the main species survived with an increased quantity.The three types of electrogenic bacteria such as Firmicutes,Actinobacteria and Proteobacteria played an important role. |
