摘要: 抗生素的滥用导致了环境中抗性基因的产生,抗性基因一旦形成便难以控制和消除。目前,抗性基因在水环境中普遍检出,传播扩散迅速,污染形势严重,对生态系统和人体健康构成了巨大威胁。本文综述了国内外关于去除水环境中抗性基因的技术进展,重点讨论了消毒技术(含紫外消毒和加氯消毒)、高级氧化技术(包括Fenton氧化、光催化氧化和臭氧氧化)和人工湿地技术对水中抗性基因的去除效果,指出了各技术的应用优势和限制,分析了存在的问题与解决措施,为今后这一方向的深入研究和实践应用提供科学依据和参考。

Abstract:

The abuse of antibiotics has led to the emergence of antibiotic resistant genes (ARGs). ARGs are difficult to be eliminated from the environment. Nowadays, ARGs have been constantly detected in water and propagated quickly. The pollution of ARGs is a critical problem, posing a serious risk to both ecosystems and human health. This review summarized some important progresses in the methods of removing ARGs from water environment. The removal of ARGs by different treatment processes such as ultraviolet disinfection, chlorination, advanced oxidation (including Fenton oxidation, photocatalytic oxidation, and O3 oxidation), and constructed wetlands was discussed. The advantages and limitations of the applications of these treatments were pointed out. Problems existing in the technologies and solutions were also analyzed, which provided references for future research.
