Research Progress on Elimination Methods of Antibiotic Resistance Genes in Drinking Water Environment
Antibiotic resistance genes(ARGs)are kinds of genes present within the genomes of bacteria and other microorganisms,which confer resistance to specific antibiotics.As a novel type of contaminant,ARGs have emerged as a significant threat to global public health.These genes can infiltrate the drinking water systems through various pathways,including improper sewage treatment,agricultural runoff,and discharges from hospitals and industrial facilities.It is very important to control ARGs in drinking water environment by using ARGs elimination method for drinking water safety.The elimination methods of ARGs in drinking water environment mainly include traditional elimination methods and novel elimination methods.The traditional elimination methods are mainly used to eliminate ARGs during the drinking water treatment process,such as flocculation,precipitation,disinfection,filtration,etc.,so as to achieve the purpose of preventing and controlling ARGs.The novel elimination methods are those that have not been widely used in drinking water treatment processes but have positive application prospects.The application of ultraviolet/peroxyacetic acid disinfectant can improve the elimination efficiency of ARGs in the disinfection process,which is a promising elimination method.Advanced oxidation technology is also an effective method to eliminate ARGs.In advanced oxidation technology,the oxidizer interacts with ARGs at the molecular level and produces surface oxidation reaction to achieve the elimination of ARGs.Auxiliary disinfectants are an important direction in ARGs elimination research and the active substances from natural sources are mainly used to improve the elimination efficiency of ARGs in drinking water disinfection process.In addition,ARGs specific adsorption materials is the development trend of ARGs elimination,although this has not been used in drinking water treatment process,its prospects should not be underestimated.With the continuous development of elimination methods,new directions and contents of ARGs research have been put forward,mainly including the innovation of ARGs detection technology and methods,the study of ARGs distribution and migration,so as to promote the innovative development of ARGs elimination methods.In view of this,this paper summarizes the elimination methods of ARGs in drinking water environment,and puts forward suggestions and prospects for the focus and trend of future ARGs research,aiming at providing scientific basis and technical support for exploring effective prevention and control strategies of ARGs.
