Hospital wastewater contains pathogens, heavy metals, disinfectants, organic solvents, acids, bases, as well as radioactive substances. The main departments and facilities that generate wastewater in hospitals include: examination rooms, laboratories, wards, laundry rooms, X-ray imaging and printing rooms, animal rooms, isotope treatment and diagnosis rooms, operating rooms, etc. all with drainage outlets.

The main departments and facilities that generate wastewater in hospitals include: examination rooms, laboratories, wards, laundry rooms, X-ray imaging and printing rooms, animal rooms, isotope treatment and diagnosis rooms, operating rooms, etc. Their drainage; hospital administrative management and medical staff's domestic wastewater discharge, as well as wastewater from canteens, single dormitories, and family dormitories.
Medical wastewater not only contains a large number of pathogenic microorganisms such as bacteria, viruses and worm eggs, but also contains chemical agents and radioactive isotopes. It has several major characteristics including space pollution, acute infection and latent infection. If medical wastewater containing pathogenic microorganisms is not treated through disinfection, inactivation, etc. for harmless processing and is directly discharged into the urban sewer, it will often cause pollution to water and soil. In severe cases, it can trigger various diseases or lead to latent infections, which can induce diseases or cause harm.
The infectious disease hospital adopts secondary treatment.
2. Counties and above-level hospitals whose wastewater is discharged into natural water bodies adopt secondary treatment.
3. Comprehensive hospitals that discharge their wastewater into the city's sewer system also adopt the secondary treatment process.
4. For small general hospitals in economically underdeveloped areas, simple biochemical treatment can be adopted as a transitional measure. Subsequently, a second-level treatment or an enhanced first-level treatment should be gradually implemented.
