The occurrence of ciprofloxacin, sulfamethoxazole, tetracycline, and trimethoprim antibiotics in four full-scale wastewater treatment plants (WWTPs) that differ in design and operating conditions was determined. The WWTPs chosen utilized a variety of secondary removal processes, such as a two stage activated sludge process with a nitrification tank, extended aeration, rotating biological contactors, and pure oxygen activated sludge. Several of the WWTPs also employed an advanced treatment process, such as chlorination and UV radiation disinfection. The detected concentrations (microg/l) ranged from 0.20 to 1.4 for ciprofloxacin, 0.21 to 2.8 for sulfamethoxazole, 0.061 to 1.1 for tetracycline, and 0.21 to 7.9 for trimethoprim. The overall percent difference in the concentrations of the antibiotics in the effluent and influent of these antibiotics differed between plants and ranged from 33% to 97%. Based on these four full-scale WWTPs evaluated, the apparent removal of organic micropollutants in wastewater is dependent on a combination of biological and physico-chemical treatment processes and operating conditions of the treatment system.
测定了设计和运行条件不同的四家全规模污水处理厂（WWTPs）中环丙沙星、磺胺甲恶唑、四环素和甲氧苄啶抗生素的出现情况。所选的污水处理厂采用了多种二级去除工艺，如带有硝化池的两级活性污泥工艺、延时曝气、旋转生物接触器和纯氧活性污泥工艺。其中几家污水处理厂还采用了高级处理工艺，如氯化和紫外线辐射消毒。检测到的浓度（微克/升）范围为：环丙沙星0.20至1.4，磺胺甲恶唑0.21至2.8，四环素0.061至1.1，甲氧苄啶0.21至7.9。这些抗生素在流出物和流入物中的浓度总体百分比差异因工厂而异，范围为33%至97%。基于对这四家全规模污水处理厂的评估，废水中有机微污染物的表观去除取决于生物和物理化学处理工艺以及处理系统运行条件的组合。
