Abstract:

针对全球能源短缺和污泥处理过程中能耗较高等问题,采用微生物燃料电池(microbial fuel cell, MFC)技术处理剩余污泥并将污泥中的化学能直接转化成电能,从而实现污泥的稳定化与资源化利用.构建以铁氰化钾为阴极电子受体的双室型微生物燃料电池,分别考察了微生物燃料电池以城市污水处理厂剩余污泥为底物时的产电性能和对污泥的降解效果,并从缓冲溶液、阳极底物浓度和阳极区搅拌3个方面分析其对电池产电性能和污泥降解效果影响.电池输出电压可达到0.66 V,MFC运行一个周期,对污泥总化学需氧量TCOD (total chemical oxygen demand)的去除率为??36.4%??,阳极区缓冲溶液的投加和搅拌均可提高电能的输出及对污泥TCOD的去除能力.
