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.
