中文摘要：
以厌氧污泥作为初始接种体,构建了单室微生物燃料电池（MFCs）,考察了梯度驯化、直接驯化和间接驯化3种不同驯化方式对MFC降解苯酚及产电性能的影响。结果表明,MFC在闭路状态下对苯酚的降解速率比MFC在开路状态下的苯酚降解速率加快10%～20%,说明MFC在产电的同时,可加速苯酚的降解。当以600 mg/L的苯酚溶液为单一燃料,反应68 h后,3种驯化方式下的MFC对苯酚降解率都达到90%以上。相对于其他2种驯化方式,梯度驯化条件最有利于MFC产电性能的提高及苯酚的降解,其最大输出功率为31.3 mW/m2,降解速率提高了7%～20%。
英文摘要：
Single chamber microbial fuel cells（MFCs）were inoculated with anaerobic activated sludge.The effects of three different domestications（batch acclimation,direct acclimation and indirect acclimation） on the phenol degradation and MFC performance were investigated.The results show the phenol degradation rate in MFC under the closed-circuit is 10%~20% faster than that under the open-circuit.It implied that MFC can accelerate the degradation of phenol in the production of electricity.When MFCs use 600 mg/L phenol as the sole fuel,phenol degradation rate in MFC with three different domestications is more than 90% after 68 h.Compared to the other two acclimation,it is most conducive to improve phenol degradation and MFC performance under batch acclimation conditions,the maximal power density arrives at 31.3 mW/m2,phenol degradation rate increases 7%~20%.
