氟喹诺酮类药物是一种广谱合成抗生素，在治疗严重细菌感染中发挥着重要作用。FQs可以通过不同的途径到达污水处理厂，并最终积聚在活性污泥中。在本研究中，采用固相萃取- HPLC-FLD检测方法研究了热水解作为预处理时消化污泥中FQs的分配和归宿。结果表明，在分批厌氧消化过程中，热水解对FQs的命运影响较小，而厌氧消化单独去除bb60 %的FQs，最终有助于减轻对微生物群落的抑制作用。(C) 2017 Elsevier B.V.版权所有
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.
