摘　　要：利用苎麻生物脱胶废水作为燃料和接种体,构建并即刻成功地启动了双室微生物燃料电池,利用该微生物燃料电池进行了苎麻生物脱胶废水处理试验。结果表明,在一个反应批次内,COD去除率为55.26%,总糖浓度降低了31.91%,可溶性蛋白质浓度降低了38.71%,p H由6.4上升到6.89,微生物数量降低了50%,FTIR光谱分析进一步证实燃料电池产电的主要来源于废水中的糖类和蛋白质等有机物的氧化降解。微生物燃料电池产生的最大电压为1 096.1 m V(外电阻为2 200Ω),最大功率密度达到36.55 m W/m2,稳定期间内阻约为470Ω。在一个反应批次内,随着废水有机物的逐渐减少,燃料电池的电压随之降低。A two-chamber microbial fuel cell was successfully constructed and started up immediately using ramie bio-degumming wastewater as inoculums as well as nutritional substance. The treatment effect of ramie bio-degumming wastewater and electricity generation of the microbial fuel cell were investigated. The results showed that,in an operational cycle,the removal efficiency of COD is 55.26%,concentration of saccharides was decreased by 31.91%,concentration of soluble protein was decreased by 38.71%,p H was from 6.4 to 6.89,microbial population was decreased by 50%,the analysis result of FTIR indicated that electric power of the microbial fuel cell was derived from organics such as saccharides and protein in ramie bio-degumming wastewater primarily. Obtained maximum voltage and power density of the MFC were1 096.1 m V and 36.55 m W/m2（fixed 2 200 Ω）,respectively,and the internal resistance was about 470 Ω during steady state. Concentration of COD was decreased along with voltage during an operational cycle.
