【摘要】：抗生素的濫用導(dǎo)致了環(huán)境中抗性基因的產(chǎn)生,抗性基因一旦形成便難以控制和消除。目前,抗性基因在水環(huán)境中普遍檢出,傳播擴散迅速,污染形勢嚴(yán)重,對生態(tài)系統(tǒng)和人體健康構(gòu)成了巨大威脅。本文綜述了國內(nèi)外關(guān)于去除水環(huán)境中抗性基因的技術(shù)進(jìn)展,重點討論了消毒技術(shù)(含紫外消毒和加氯消毒)、高級氧化技術(shù)(包括Fenton氧化、光催化氧化和臭氧氧化)和人工濕地技術(shù)對水中抗性基因的去除效果,指出了各技術(shù)的應(yīng)用優(yōu)勢和限制,分析了存在的問題與解決措施,為今后這一方向的深入研究和實踐應(yīng)用提供科學(xué)依據(jù)和參考。
[Abstract]:The abuse of antibiotics leads to the production of resistance genes in the environment, which are difficult to control and eliminate once they are formed. At present, resistance genes are widely detected in the water environment, spread rapidly, the pollution situation is serious, which poses a great threat to ecosystem and human health. In this paper, the advances in removing resistant genes in water environment are reviewed, and the disinfection techniques (including ultraviolet disinfection and chlorination disinfection) and advanced oxidation techniques (including Fenton oxidation) are discussed in detail. The effects of photocatalytic oxidation and ozone oxidation) and constructed wetland on removal of resistance genes in water were pointed out, the advantages and limitations of each technology were pointed out, and the existing problems and solutions were analyzed. It provides scientific basis and reference for further research and practical application in this direction.
