The microbial electrolysis cell (MEC) is a promising technology for antibiotic removal in sewage sludge. Temperature and voltage are key operating factors, but information about their effects on antibiotic degradation in MECs is still limited. Therefore, the effects of the temperature and applied voltage on the degradation and solid–liquid distribution of antibiotics in MECs treating sewage sludge were investigated. The results showed that the thermophilic (55 °C) MEC (T-MEC) at 0.8 V achieved the highest total antibiotic removal efficiency of 58.7 % due to the increase in bioelectrochemical activity for anodes and microbial activity in suspended sludge. The solid–liquid migration of antibiotics was facilitated, which had a significant positive correlation with antibiotic removal. Biodegradation was the rate-limiting step for the removal of fluoroquinolones, which had the highest levels in sludge. Geobacter and Thermincola were dominant bacteria in the anode biofilms of mesophilic (37 °C) MECs (M-MECs) and T-MECs, respectively.

微生物电解池 (MEC) 是一种很有前途的去除污水污泥中抗生素的技术。温度和电压是关键的操作因素，但关于它们对 MEC 中抗生素降解影响的信息仍然有限。因此，研究了温度和施加电压对 MEC 处理污水污泥中抗生素降解和固液分布的影响。结果表明，由于阳极生物电化学活性和悬浮污泥中微生物活性的增加，0.8 V 的嗜热 (55 °C) MEC (T-MEC) 实现了最高的总抗生素去除效率 58.7%。促进了抗生素的固液迁移，这与抗生素去除呈显着正相关。Geobacter和Thermincola分别是嗜温 (37 °C) MEC (M-MEC) 和 T-MEC 阳极生物膜中的优势细菌。
