抗生素抗性基因(Antibiotic resistance genes,ARGs)在饮用水系统中的传播和扩散已成为全球公共健康的主要威胁之一.饮用水厂处理工艺对抗生素抗性基因的去除效果对保证饮用水水质安全具有重要意义,但是水处理工艺、消毒方式以及管网输配系统对不同抗生素抗性基因的影响差异较大.本文在总结了大量文献的基础上,阐述了饮用水系统中抗生素抗性基因的污染特征,综述了臭氧、混凝、砂滤、生物活性炭以及氯消毒和超滤膜等不同水处理工艺对抗生素抗性基因去除的影响及其机理.
The spread of antibiotic resistance genes (ARGs) in the drinking water systems has been considered as a major public health issue around the world.Drinking water treatment processes are of great significance for removing antibiotic resistance genes to ensure the safety of drinking water.However,water treatment techniques,disinfection methods and drinking water distribution systems have distinct impacts on different antibiotic resistance genes.On the basis of previous literatures,this paper summarized the pollution characteristics of antibiotic resistance genes and research progress in the drinking water systems.The effects on the removal of the antibiotic resistance genes and their mechanisms by different water treatment processes,including ozonation,coagulation/flocculation,sand filtration,biological activated carbon (BAC),ultrafiltration membrane and chlorination were reviewed.
