摘    要:以含油污泥为阳极底物构筑了沉积型微生物燃料电池(SMFC),通过检测输出电压、功率密度、表观内阻和原油去除效果等性能指标,分别考察了阳极填料、电极面积、pH对SMFC的性能影响.结果表明:相比活性炭填料,碳毡填料使SMFC发电性能更优且原油去除率提高了8.03%;增加电极面积,SMFC内阻减小、发电性能和原油去除率得到提升;酸性或碱性阳极底物不利于SMFC发电和降解油污,而阳极底物的pH=7.5时,SMFC的发电及油污降解性能最佳,输出电压和原油去除率分别达373.7 mV、45.36%.

关 键 词:含油污泥    沉积型微生物燃料电池    除油    电极面积    pH    电池填料

Abstract:A sedimentary microbial fuel cell(SMFC) was constructed using oily sludge as anode substrate. The influence of anode packing, electrode area and pH on SMFC performance was investigated by measuring the output voltage, power density, apparent internal resistance and crude oil removal effect. The results showed that, compared with activated carbon filler, carbon felt packing endowed SMFC with better electricity generation performance and the removal rate of crude oil increased by 8.03%. The internal resistance decreased and the electricity generation performance and crude oil removal rate improved with the increasing of electrode area of SMFC. Acid or alkaline anode substrates were unfavorable to the power generation and degradation of SMFC. When the pH of the anode substrate is 7.5, the power generation and degradation performance of SMFC were the best. The generating voltage and removal rate of crude oil reached 373.7 mV and 45.36% respectively.
