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(MnO/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, respectively.

摘要

本研究的目的是探究不同改性阳极对微生物燃料电池（MFC）的影响以及MFC对难处理废水的处理效果。基于单室空气阴极，分别用0.10 g电气石、75%二氧化锰/埃洛石纳米管（MnO/HNT）和多壁碳纳米管-羧基（MWCNT-COOH）对MFC的阳极进行改性。结果表明，在具有不同改性阳极的MFC中，纯对苯二甲酸（PTA）的去除率高于70%，化学需氧量（COD）去除率超过79%。与其他相比，具有MWCNT-COOH改性阳极的MFC获得了最大输出电压和最大功率密度，分别为529 mV和252.73 mW·m² 。
