At the TC concentration of 20–80 mgL-1 in feed, the removals of tetracycline all exceeded 95%, over 60–1200 mgL-1 chemical oxygen demand, 30–150 mgL-1 NH4+-N, and at 5–25 °C, superior to the performances reported in literature. The maximum power of the BES system peaked at 0.416 Wm?3 at 20 mgL-1 TC feeding, corresponding to open circle voltage of 0.90 V and internal resistance of 799.8 Ω. The community analysis showed that the elevated TC loadings forced the predominate population to be evolved to TC-degrading consortium. The relative abundances of tetA, tetC, tetO, tetQ, and tetW in treated effluent ranged 1.20 × 10-6 to 2.60 × 10-4, revealing that the present BES reactor has superior removal efficiency of antibiotic resistance genes. ? 2022 Elsevier Ltd |
