Sulfonamide antibiotics (SMs), as a class of antibiotics commonly used in swine industries, pose a serious threat to animal and human health. This study aims to evaluate the performance of an anaerobic membrane bioreactor (AnMBR) with and without supplying a new pomelo peel derived biochar to treat swine wastewater containing SMs. Results show that 0.5 g/L biochar addition could increase more than 30% of sulfadiazine (SDZ) and sulfamethazine (SMZ) removal in AnMBR. Approximately 95% of chemical oxygen demand (COD) was removed in the AnMBR at an influent organic loading rate (OLR) of 3.27 kg COD/(m·d) while an average methane yield was 0.2 L/g COD with slightly change at a small dose 0.5 g/L biochar addition. SMs inhibited the COD removal and methane production and increased membrane fouling. The addition of biochar could reduce the membrane fouling by reducing the concentration of SMP and EPS.
磺胺类抗生素（SMs）作为一种在养猪业中广泛使用的抗生素，对动物和人类健康构成了严重威胁。本研究旨在评估在不添加和添加新柚子皮衍生生物炭的情况下，厌氧膜生物反应器（AnMBR）处理含有 SMs 的猪废水的性能。结果表明，添加 0.5 g/L 的生物炭可使磺胺嘧啶（SDZ）和磺胺甲噁唑（SMZ）的去除率提高 30%以上。在进水有机负荷率（OLR）为 3.27 kg COD/（m·d）的情况下，AnMBR 中约有 95%的化学需氧量（COD）被去除，而在添加小剂量 0.5 g/L 生物炭时，平均甲烷产量为 0.2 L/g COD，略有变化。SMs 抑制了 COD 的去除和甲烷的产生，并增加了膜污染。生物炭的添加可以通过降低 SMP 和 EPS 的浓度来减少膜污染。
