Medical wastewater contains not only a large number of pathogenic microorganisms such as bacteria, viruses, and eggs, but also a large number of chemical agents and radioisotopes, which have three characteristics of space pollution, acute infection and latent infection.The direct discharge of medical wastewater will cause great damage to water resources, and the impact will be greater than that of industrial wastewater。AOPs can not only directly kill and disinfect viruses, bacteria, fungi and other substances in wastewater, but also remove refractory organic matter in wastewater, greatly reducing the harm of medical wastewater to water environment.
