| 摘 要： | 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).

| Abstract: | The purpose of this study was to investigate the effect of different modified anodes on the microbial fuel cell(MFC) and the effect of MFC on the treatment of refractory wastewater. Based on a single room air cathode, the anode of MFC was modified by 0.10 g of tourmaline, 75% manganese bioxide/halloysite nanotube(MnO2/HNT) and multi-walled carbon nanotube-carboxyl(MWCNT-COOH), respectively. The results showed that, the removal rate of purified terephthalic acid(PTA) was higher than 70%, and the chemical oxygen demand(COD) removal rate was more than 79% in MFC with different modified anodes. Compared with others, MFC with MWCNT-COOH modified anode obtained the maximum output voltage and maximum power density, which were 529 mV and 252.73 mW·m-2, respectively. |
