Evaluation of a continuous flow microbial fuel cell for treating synthetic swine wastewater containing antibiotics

Microbial fuel cell (MFC) systems are promising technologies for wastewater treatment and renewable energy generation simultaneously. Performance of a double-chamber microbial to treat synthetic swine containing sulfonamide antibiotics (SMs) was evaluated in this study. The MFC operated continuous modes at different conditions. Results indicated that the current successfully generated during operation. performance under sequential anode-cathode operating mode is better than single running mode. Specifically, higher removal efficiency chemical oxygen demand (>90%) achieved comparison with (>80%). Nutrients were also be removed MFC's cathode chamber maximum 66.6 ± 1.4% NH4+-N 32.1 2.8% PO43?-P. Meanwhile, SMs partly value range 49.4%–59.4% sulfamethoxazole, 16.8%–19.5% sulfamethazine 14.0%–16.3% sulfadiazine, respectively. SMs' inhibition remove other pollutants both electrodes observed after exposure, suggesting exert toxic effects on microorganisms. A positive correlation found between concentration used study chamber. In short, although flow feasible treating antibiotics, its requires further improved.
