Fluoroquinolones (FQs) are broad-spectrum synthetic antibiotics that play an important role in the treatment of serious bacterial infections. FQs can reach wastewater treatment plants from different routes, and eventually accumulate in activated sludge. In this study, a solid-phase extraction (SPE) with HPLC-FLD detection method was utilized to investigate the partition and fate of FQs in digested sludge when thermal hydrolysis was used as pretreatment. As a result, thermal hydrolysis showed minor effects on the fate of FQs in batch anaerobic digestion processes, while anaerobic digestion alone removed >60% FQs and finally assisted in the mitigation of the inhibitory effects to microbial communities.
氟喹诺酮类药物（FQs）是一种广谱合成抗生素，在治疗严重细菌感染方面发挥着重要作用。FQs 可以通过不同的途径进入到污水处理厂，并最终在活性污泥中积累。在本研究中，采用固相萃取（SPE）和高效液相色谱-荧光检测法（HPLC-FLD）来研究热解作为预处理时 FQs 在消化污泥中的分配和归趋。结果表明，热解对分批厌氧消化过程中 FQs 的归趋影响较小，而单独的厌氧消化可以去除 >60%的 FQs，并最终有助于减轻对微生物群落的抑制作用。
