| 摘 要： | 抗生素在环境中作为一种新型污染物,是目前污水处理厂中重要的污染物之一.为考察小城镇污水处理厂对抗生素的去除效果,选择3种典型小城镇污水处理工艺(CASS、A~2/O及Orbal氧化沟工艺),研究了4种四环素类、3种β-内酰胺类、4种大环内酯类、3种喹诺酮类和2种磺胺类在进出水中的浓度分布、去除情况以及不同工艺抗生素去除效率,并对抗生素浓度与水质常规指标的相关性进行分析.结果表明,所研究的污水处理厂中氧氟沙星和诺氟沙星为主要抗生素,并且去除效果较好.5个污水处理厂运行情况良好,CASS工艺和Orbal氧化沟工艺对大部分抗生素的去除效果比A~2/O工艺好,抗生素去除率均能达到60%以上.同时,发现CASS工艺和A~2/O工艺对β-内酰胺类(氨苄西林、青霉素)、喹诺酮类(恩诺沙星、氧氟沙星和诺氟沙星)和大环内酯类(克拉霉素)的去除效果最好,Orbal氧化沟工艺对四环素类(四环素、土霉素)和磺胺类(磺胺嘧啶)的去除效果最好.将抗生素浓度和水质基本参数(NH_4~+-N、TN、COD、pH等)进行相关性分析后,发现抗生素浓度与水质基本参数NH_4~+-N、COD呈一定正相关,污染物浓度越高,红霉素(EM)、罗红霉素(ROX)、差向四环素盐酸盐(ETC)、克拉霉素(CLR)、环丙沙星(CIP)、氧氟沙星(OFX)、差向土霉素(E-OTC)、四环素(TC)、土霉素(OTC)以及诺氟沙星(NOR)的浓度也相对更高,这为确保小城镇污水厂的稳定运行,降低抗生素类污染物的生态风险提供了重要参考.
