The anode plays an important role in the improvement of power generation. Zeolite and carbon-based materials were coated in graphene felt anode in this study for proof of concept that the modified material could enhance power generation. Preliminary results showed that the maximum power density with the modified material was 2 - 2.5 times higher than the unmodified material using RAS as a substrate and 1.4 times higher using algae as a substrate in our single chamber model, whereas the dual-chamber model displayed a maximum power density of the modified material to be roughly 3 - 4 times higher than in the unmodified microbial fuel cell.展开更多
文摘实验以碳刷、活性炭、石墨、碳毡为阳极材料,采用双室生物阴极型MFC对乙酸钠废水进行处理,对比了4种材料对MFC的启动、产电性能、内阻和水质处理效果的影响。结果表明,当底物浓度为1 000 mg/L,外电阻为500Ω时,以活性炭为阳极的MFC启动最快,在稳定阶段的产电性能和水质处理效果在4个MFC中均是最好的,其最大功率密度为324.2 m W/m2,COD去除率达到90%以上。在长期运行后,以活性炭、石墨、碳毡为阳极的MFC产电能力和水质处理效果均出现下降趋势,只有以碳刷为阳极的MFC能够保持较稳定的产电能力和水质处理效果。
