摘　　要： 构建双室微生物燃料电池(MFC),分别以单一葡萄糖、苯酚和葡萄糖、单一苯酚为底物运行MFC,对有机物在MFC中的降解以及MFC产电性能进行研究。试验结果表明,MFC产电性能良好,运行稳定,以500mg/L葡萄糖为单一底物时,MFC最高输出电压可达630mV,最大功率密度为21.57mW/m2,COD去除率为54.74%。以苯酚和葡萄糖为MFC混合底物时,MFC的产电性能及有机物去除率随底物中苯酚比例的增加而降低,说明底物生物降解的难易对MFC的产电性能具有一定影响。以500mg/L苯酚为MFC单一底物时,MFC的最高输出电压为201,COD、苯酚去除率分别为31.10%、28.0%,表明MFC能够利用苯酚作为底物,在降解苯酚的同时稳定向外输出电能。 A double-chamber microbial fuel cell （MFC） was constructed for biodegradation of phenol with sim- ultaneous electricity generation. Effect of different fuel substrate （single glucose, mixture of glucose and phenol and single phenol） on power generation of MFC was ivestigated through the batch experiments. Results showed that the MFC was operated stable with perfect electrogenesis capacity, using 500 mg/L glucose as single fuel substrate, the MFC achieved the maximum voltages of 630 mV and maximaI power densities of 21.57 mW/m2 , the COD removal rate could reached to 54.74% during one cycle of operation. Using the mixture of glucose and phenol as fuel sub strate, the electrogenesis capacity and organic removal rate was decreased with increasing the proportion of glucose in fuel substrate. This indictaed that the biodegradability of fuel substrate had certain effect on MFC electrogenesis ca- pacity. The maximum voltage was 201 mV when using 500 mg/L of phenol as sole fuel substrate. The COl）, phenol removl rate was 31.10%, 28.0% respectively during one cycle of operation. The results indicated that phenol could be used in the MFC for generating power while effectively accomplishing biodegradation simultaneously. The MFC technology may provide a new method to treat organic wastewater.
