摘　　要：环境水体中残留的抗生素所引起的生态毒害问题已经引起了世界范围内的高度关注与重视。目前,大多数给水厂采用的常规处理工艺无法有效去除水中抗生素。文中对比了活性炭吸附、紫外降解以及紫外光+活性炭联合处理这三种深度处理工艺对水体中典型磺胺类抗生素的去除效果。结果表明,在浓度为5 mg/L的情况下,单一紫外降解对于磺胺类抗生素的去除率只有20%左右,单一活性炭吸附对于磺胺类抗生素的去除率可达90%以上,紫外光+活性炭联合处理对于磺胺类抗生素的去除率可达95%以上。试验结果为实际工程应用提供了一定的技术支持。Abstract The pollution and ecological poisoning problems caused by antibiotic residual in environmental water body have been got widely attention. At present, most of water treatment plants which apply conventional treatment process can not effectively remove water antibiotics. This paper discusses advanced treatment processes through comparison of removal effect of sulfonamides in water by activated carbon adsorption, UV degradation and UV ＋ activated carbon processes. The results show that in the case of a concentration of 5 mg/L sulfonamide, the degradation rate of single UV degradation for sulfonamides is only about 20%, and that of the latter two processes reach 90% and 95% or more, respectively. The experimental results also provide some technical support for practical engineering applications.
