中文摘要: |
通过比较相同COD浓度的三种不同阳极底物:象草秸秆水解液,葡萄糖模拟废水,葡萄糖与象草秸秆水解产物共基质溶液,研究不同阳极底物对MFC的产电电压、产电时间、功率密度、内阻、库伦效率及底物的COD去除率的影响。得出结论是葡萄糖和象草秸秆水解产物共基质溶液作为MFC阳极底物时可获得较高电压,且稳定产电的时间较长;获得的最大功率密度为380.63mW.m-2;具有最小的内阻155.97Ω;库伦效率为22.64%;底物的COD去除率为83.2%,可作为MFC阳极底物。 |

Compared with the same COD concentration of three different anode substrates: Elephantgrass straw hydrolysate, glucose simulated wastewater, hydrolysis product of glucose and grassiness straw co substrate solution, effects of different anode substrates to produce electric voltage, electricity production time, power density, internal resistance, Kulun efficiency and substrate COD removal rate of MFC. The conclusion is that glucose and grassiness straw hydrolysate solution as co substrate MFC anode substrate can obtain higher voltage, and stable electricity production over a long period of time; the maximum power density was 380.63mW.m-2; with the lowest resistance 155.97Ω; Kulun efficiency 22.64%; substrate removal rate of COD is 83.2%, which can be used as MFC the anode substrate. |
