Meanwhile, the related legislation of the country also needs to follow up in time, more definite regulations are made for the treatment of medical wastewater, and environmental protection departments at all levels also need to strengthen the popularization of management and environmental protection awareness. Compared with industrial wastewater, the medical wastewater has larger influence and harm on the environment. Hospitals inevitably produce waste water with direct or indirect infectivity, toxicity and other hazards during the operation, and the source of the waste water determines the complexity of the components of the waste water and relates to various biological, chemical or radioactive pollutions. The medical wastewater contains a large amount of pathogens such as bacteria, viruses, ova and the like, and also contains chemical agents and radioactive isotopes, and has several characteristics of space pollution, acute infection and latent infection. If medical sewage containing pathogenic microorganisms is directly discharged into urban sewers without being subjected to harmless treatment such as disinfection and inactivation, the pollution of water and soil is often caused, various diseases are seriously caused, or the outbreak of water infectious diseases is caused.
Along with the development of economy and the attention of the public on oral problems, the number of oral clinics is increased rapidly, and the oral clinics are mainly characterized by being small and many and are generally distributed in communities. A large amount of sewage is generated in the diagnosis and treatment process of the dental diagnosis, the sewage contains a large amount of pathogenic bacteria, viruses, ova and the like, and also contains chemical agents, so that the sewage has the characteristics of space pollution, acute infection, latent infection and the like, is very harmful, and if the sewage is not properly treated, the living environment health and the water quality safety of people are seriously influenced.
