摘要
      氟喹诺酮类（FQs）是广谱合成抗生素，在严重细菌感染的治疗中发挥重要作用。 FQs可以从不同途径到达污水处理厂，并最终积聚在活性污泥中。 本研究采用固相萃取 - 高效液相色谱 - 荧光检测法（SPE-SPE），研究了热解水解预处理后消解污泥中FQs的分配与去向。 因此，热水解对间歇厌氧消化过程中FQs的影响较小，而单独的厌氧消化则去除了> 60％FQs，最终有助于缓解对微生物群落的抑制作用。

       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.
