Hospital wastewater originates from multiple sources, including hospital canteens, restrooms, reagent rooms, operating rooms and other areas. It is a composite of wastewater discharged from these locations. Generally low in concentration, its quality is similar to ordinary domestic sewage, containing primarily organic and inorganic pollutants. However, hospital wastewater is characterized by a high content of pathogenic bacteria, viruses, parasites, and other complex components.

Such wastewater cannot be discharged directly. Direct discharge into water bodies would cause severe pollution to surrounding waters and soil, thereby endangering public health. Therefore, Medical Wastewater Monitoring has become a critical task to ensure water safety. Below are key requirements for medical wastewater testing:

1. The design and construction of medical wastewater treatment processes must comply with relevant standards and specifications issued by the State Planning Commission and the Environmental Protection Bureau.
2. Both existing and new health institutions must ensure proper treatment of wastewater contaminated by pathogenic bacteria to guarantee safe discharge.
3. Wastewater containing radioactive substances, heavy metals, or other hazardous materials that fails discharge standards must undergo specialized treatment before being discharged into the wastewater treatment station or sewer.
4. Newly built, renovated, or expanded wastewater treatment facilities must be designed, constructed, and commissioned simultaneously with the main project.
5. The treatment system must deliver high efficiency, easy management, and a small footprint, while avoiding secondary pollution to the surrounding environment during operation.
6. Wastewater treatment facilities must be corrosion-resistant and leak-proof. All structures must be covered and sealed with proper ventilation.
7. Facilities (e.g., regulating tanks, sedimentation tanks) must be installed in duplicate, with each unit designed for 50% of the total load.
8. The design of continuous contact tanks must adhere to relevant specifications.
9. The effective volume of the metering tank must be calculated as one-quarter of the total wastewater volume.
