A sequential anode-cathode double-chamber microbial fuel cell (MFC) is a promising system for simultaneously removing contaminants, recovering nutrients and producing energy from swine wastewater. To improve sulfonamide antibiotics (SMs)'s removal in the continuous operating of MFC, one new pomelo peel-derived biochar was applied in the anode chamber in this study. Results demonstrated that SMs can be absorbed onto the heterogeneous surfaces of biochar through pore-filling and π-π EDA interaction. Adding biochar to a certain concentration (500 mg/L) could enhance the efficiency in removing sulfamethoxazole, sulfadiazine and sulfamethazine to 82.44-88.15%, 53.40-77.53% and 61.12-80.68%, respectively. Moreover, electricity production, COD and nutrients removal were improved by increasing the concentration of biochar. Hence, it is proved that adding biochar in MFC could effectively improve the performance of MFC in treating swine wastewater containing SMs.
顺序式阴阳极双室微生物燃料电池（MFC）是一种很有前途的系统，可以同时从猪废水中去除污染物、回收营养物质并产生能源。为了提高 MFC 连续运行中磺胺类抗生素（SMs）的去除率，本研究在阳极室内应用了一种新的柚子皮衍生生物炭。结果表明，SMs 可以通过孔填充和π-π EDA 相互作用吸附到生物炭的非均相表面上。将生物炭添加到一定浓度（500mg/L）可以分别将磺胺甲恶唑、磺胺嘧啶和磺胺甲噻二唑的去除效率提高到 82.44-88.15%、53.40-77.53%和 61.12-80.68%。此外，通过增加生物炭的浓度可以提高电能生产、COD 和营养物质的去除率。因此，证明在 MFC 中添加生物炭可以有效地提高 MFC 处理含 SMs 的猪废水的性能。
