摘要
探讨了不同浓度葡萄糖和秸秆水解产物共基质溶液对电能的输出影响,并检测了产电微生物的种类。随着阳极底物质量浓度(50,500,1 000,1 500,2 000,2 500 mg/L)的升高,电池的最大开路电压依次为725,1 286,1 273,1 318,1 165,1 280 m V。当质量浓度为1 500 mg/L时,电池产电性能最高,其最大输出功率密度为363.38 m W/m2,内阻为191.68Ω,COD去除效率为82.8%,库伦效率为18.83%。利用16Sr DNA技术分析了微生物燃料电池的菌群结构,结果显示,阳极主要产电微生物为铜绿假单胞菌和枯草芽孢杆菌。
In this paper ,the influence of different concentrations of co -substrate solution of glucose and straw effects hy-drolysates on power output are discussed and also the microbial species are detected .With the increase of the anode substrate concentration （50 ,5 00 ,1 000 ,1 500 ,2 000 ,2 500 mg/L ） ,the maximum open-circuit voltage of battery is 725 ,1 286 , 1 273 ,1 318 ,1 165 ,1 318 mV respectively .When the concentration is 1 500 mg/L ,the performance of electricity produc-tion reaches the highest ,its maximum output power density is 363 .38 mW/m2 ,internal resistance is 191 .68 Ω ,the removal efficiency of COD is 82 .8% and coulombic efficiency is 18 .83% .16SrDNA technology is applied to analyze the flora struc-ture of microbial fuel cells and the result show that the main anode electrogenesis microorganism is Pseudomonas aeruginosa and Bacillus subtilis .
