| 摘 要： | 构建一种新型三室微生物脱盐电池(MDC),研究其脱盐产电并同步处理污染废水的效果。结果表明,阳极室为葡萄糖溶液,中间室盐溶液浓度5 g/L,阴极室为铁氰化钾溶液,闭合体系瞬时获得最高电压650 mV,同时脱盐效果良好,该MDC成功启动。其后,阴极室以重金属铬(200 mg/L)废水作为电子受体,中间室初始盐浓度为20 g/L、35 g/L,Cr(Ⅵ)平均还原率分别为1.06 mg/(L.h)和0.64 mg/(L.h),两者Cr(Ⅵ)的去除率均能达到80%以上,脱盐率分别为81.64%(20 g/L)和88.95%(35 g/L)。中间室盐浓度20 g/L时,获得最大输出电压466.6 mV,最大体积功率密度98.6 mW/m3,最佳内阻655.8Ω,库仑效率1.16%。表明该MDC系统具有良好的脱盐效果和处理废水效果。
