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.
