【摘要】 为了探讨污水中复杂有机质对微生物燃料电池性能的影响,该文通过选取同等浓度的乙酸钠、葡萄糖、庶糖、D-木糖、可溶淀粉5种原料,进行了微生物燃料电池产电性能的试验研究。在体积质量为8g/L条件下,以乙酸钠、葡萄糖、D-木糖、蔗糖和淀粉构建的MFC(生物燃料电池)中,乙酸钠电池内阻64Ω,最大体积功率密度达到3.7W/m~3;葡萄糖电池内阻84Ω,最大功率密度2.67W/m~3;D-木糖电池内阻为167Ω,最大功率密度为1.37W/m~3;蔗糖电池内阻为68.3Ω,最大功率密度为2.4W/m~3;淀粉内阻236Ω,最大功率密度1.36W/m~3。结果表明:MFC可利用各种含糖有机物进行产电,在同等条件下,底物越简单,电池启动时间越短,内阻越小,输出功率大,库仑效率大。更多还原

【Abstract】 The effects of complex compounds in the wastewater as substrate on the electricity generation performance of MFC were studied in this paper with the same concentration of sodium acetate,glucose,sucrose,D-xylose and soluble starch as substrates of MFC.Under the condition of the same concentration of 8 g/L,the MFC with sodium acetate had internal resistance 64Ω,the maximum volume power density was 3.7 W/m~3;The MFC with glucose had internal resistance of 84Ω,the maximum volume power density was 2.67 W/m~3,D-xylose voltage had the internal resistance of 167Ω,maximum power density 1.37 W/m~3;sucrose had internal resistance of 68.3Ω,maximum power density of 2.4 W/m~3;the resistance and maximum power density of MFC with starch were 236Ωand 136 W/m~3,respectively.The results showed that MFC could generate the electricity with different organic material.And at the same condition,the simpler the organic compound construction was,the smaller the internal resistance was,the higher the output power was.更多还原
