探讨了不同改性阳极对微生物燃料电池(microbial fuel cell,MFC)产电性能及其对MFC处理难降解废水能力的影响.以单室空气阴极为基础,利用0.1 g电气石、质量分数75%二氧化锰/埃洛石纳米管(manganese bioxide/halloysite nanotube,MnO_2/HNT)和多壁碳纳米管-羧基(multi-walled carbon nanotube-carboxyl,MWCNT-COOH)对MFC阳极进行修饰.结果表明,不同改性阳极的MFC对含精对苯二甲酸(purified terephthalic acid,PTA)废水的去除率均高于70%,且化学需氧量(chemical oxygen demand,COD)去除率在79%以上.相较于其他几种改性阳极,以MWCNT-COOH改性材料作阳极的MFC产生的最大输出电压最高,获得的最大功率密度最高,分别为529 mV和252.73 mW·m~(-2).
The effects of different modified anodes on the electricity generation performance of microbial fuel cells (MFC) and their ability to deal with the refractory wastewater were studied.According to single-chamber air cathode, 0.1 g tourmaline, 75% The anode of MFC was modified by manganese dioxide / halloysite nanotube (MnO 2 / HNT) and multi-walled carbon nanotube-carboxyl (MWCNT-COOH) MFCs with different modified anodes both had a removal efficiency of higher than 70% for purified terephthalic acid (PTA) wastewater and a COD removal rate above 79% Compared with other modified anodes, MFC with MWCNT-COOH as anode possessed the highest maximum output voltage, and got the highest maximum power density of 529 mV and 252.73 mW · m -2, respectively.
