摘要
根据我国已有的研究结果,综述了几类主要的抗生素在我国污水厂中的分布及去除途径,综合评价了污水处理厂中使用较为广泛的几种处理工艺在去除抗生素方面的差异。结果表明,经济发达地区对同一抗生素的去除效果要好于发展相对落后的地区,我国污水厂中氟喹诺酮类和磺胺类抗生素的检出率和检测浓度都很高,不同地区同一生物处理工艺对氟喹诺酮类抗生素都表现出较好的去除效果。污水处理厂的常规工艺对抗生素的去除率较低,单纯地采用某一种工艺很难对有机污染物进行降解,对于含有多种抗生素的污水处理厂来说,抗生素的存在降低了污水处理效果。生物处理工艺与膜处理法、高级氧化法联用是一种可行的抗生素处理方法,可以使抗生素去除率超过80%。
According to the existing research results,the distribution and removal paths of several main antibiotics in wastewater treatment plants in China were summarized,and several treatment processes widely used in wastewater treatment plants for antibiotic removal were comprehensively evaluated.The results showed that the removal effect of the same antibiotics in economically developed areas was better than that in relatively backward developed areas.The detection rate and the detected concentration of fluoroquinolones and sulfonamides in wastewater treatment plants in China are very high,and the same biological treatment process of the wastewater treatment plants in different areas shows good removal of fluoroquinolones.The removal rate of antibiotics by conventional treatment process in wastewater treatment plants is low,and it is difficult to degrade organic pollutants simply by a certain process.For wastewater containing various types of antibiotics,the presence of antibiotics reduces the removal effect of organic pollutants in wastewater treatment plants.The combination of biological treatment,membrane treatment and advanced oxidation is a feasible strategy for antibiotics treatment,which can make the removal rate of antibiotics more than 80%.
