摘要
通过对上海市饮用水厂的采样检测，初步研究了原水中磺胺类、喹诺酮类、大环内酯类典型抗生素在水厂的去除特点，分析了出厂水中抗生素的健康风险现状。研究显示，常规处理水厂对抗生素的去除率为13.01%-94.25%，出厂水中抗生素浓度为0.05-20.38 ng/L；深度处理水厂的抗生素去除率为47.85%-100%，出厂水浓度为0.13-8.34 ng/L，深度处理水厂对抗生素的去除效果优于常规处理。就抗生素种类而言，去除效果上大致呈现磺胺类优于大环内酯类，优于喹诺酮类；磺胺甲恶唑（SMX）和环丙沙星（GIP）在出厂水中浓度相对最高，分别为8.34-20.38 ng/L和2.70-27.20 ng/L。臭氧氧化、沉-砂滤具有一定的抗生素去除效果。健康风险分析显示，两个水厂出厂水中抗生素均不存在健康风险。
Distribution and removal of 13 antibiotics, including sulfonamides, quinolones and macrolides, in the conventional and advanced drinking water treatment progresses were studied, and their health risk was assessed. Results showed that, 10 antibiotics were detected. The removal rates of antibiotics during the conventional drinking water treatment progress ranged from 13.01% to 94.25%, concentrations of antibiotics were 0.05 to 20.38 ng/L in the finished drinking water. In comparison, higher removal rates of antibiotics, ranging from 47.85% to 100%, were observed in the advanced treatment progress, with concentrations of 0.13 to 8.34 ng/L in the finished water. Sulfonamides had higher removal rates than macrolides, followed by quinolones. Ozonation and biological activated carbon exhibited better removal for antibiotics. No health risk was found for the detected antibiotics in the drinking water.
