The sources and components of hospital sewage are complex and highly hazardous. The sewage contains a large amount of pathogenic bacteria and chemical agents, and has the characteristics of spatial pollution, acute infection, and latent infection. If hospital sewage containing original microorganisms is discharged directly into urban sewage pipes or environmental water bodies without disinfection treatment, it often causes water pollution, leading to various diseases and infectious diseases, seriously endangering people's health.

Disinfection is the final defense against residual bacterial pollutants after various methods of treatment, and chlorine oxygen disinfection is the disinfection method. Oxygen based disinfectants have the characteristics of rapid sterilization, * *, and broad-spectrum. Chlorine based disinfectants are disinfectants that play an important role in preventing waterborne diseases. After chlorine is added to pure water without organic matter, it quickly forms cold chlorine acid. Cold chlorine acid only takes a few minutes to kill Escherichia coli, but it takes an hour to kill certain viruses; If organic matter is present in water, chlorine will react with these substances. Unless a large amount of chlorine is added, free chlorine will not appear in the water. Disinfectants must come into effective contact with bacteria in order to kill them. To ensure optimal sterilization, a certain amount of contact time is required, and good mixing is one of the necessary conditions to improve sterilization efficiency.

According to the characteristics of medical wastewater quality and the adopted discharge standards, the commonly used treatment technology is to enter the aerobic biological treatment unit after passing through the grid and regulating tank, and then disinfect and discharge the treated wastewater. The commonly used aerobic biological treatment unit is traditional processes such as contact oxidation The commonly used disinfection methods currently include liquid chlorine or chlorine dioxide disinfection, ultraviolet light disinfection, and ozone disinfection. The current common defects are mainly manifested in several aspects: (1) Open type tanks are often used, especially for aerobic biochemical treatment. Due to the need for aeration, there will be a large amount of other emissions, and the aerosols in these gases will carry microorganisms and diffuse into the atmosphere. The sewage treatment device itself is a source of pollution. (2) The operation is not standardized, the degree of automation detection and control is low, and (3) some processing sites occupy a large area, resulting in high operating costs.

Principles of Hospital Wastewater Treatment

1. Principle of whole process control. Control the entire process of hospital wastewater generation, treatment, and discharge.

2. Principle of reduction. Strictly implement the hospital's internal hygiene and safety management system, and strictly control and separate sewage and waste sources. Domestic sewage and ward sewage are collected separately in the hospital, that is, source control and clean sewage separation. It is strictly prohibited to dispose of hospital sewage and waste into the sewer system at will.

3. Principle of on-site handling. To prevent pollution and harm during the transportation of hospital sewage, on-site treatment must be carried out in the hospital.

Four classification guidelines. Classify and guide hospital sewage treatment based on hospital nature, scale, sewage discharge destination, and regional differences.

The principle of combining compliance with risk control. Comprehensively consider the basic requirements for sewage discharge standards in comprehensive hospitals and infectious disease hospitals, while strengthening risk control awareness, and improving the ability to respond to emergencies from the aspects of process technology, engineering construction, and supervision and management.

6 Ecological security principles. Effectively removing toxic and harmful substances from wastewater, reducing the production of disinfection by-products during the treatment process, and controlling high residual chlorine in effluent to protect ecological environment safety.
