Shen ChangHong Medical sewage refers to the sewage discharged by hospitals (general hospitals, professional hospitals and other types of hospitals) to the natural environment or urban pipelines. In addition to the general domestic sewage, the water quality also contains chemicals, radioactive waste water and pathogens. Therefore, it can only be discharged after treatment, especially the sewage discharged from infectious disease wards such as hepatitis can only be discharged after disinfection and sterilization.
In recent two years, various clinics (orthopedics, anorectal, internal medicine, stomatology and other clinics) have been widely concerned about the sewage discharge, which may be strictly required to implement the medical sewage discharge standards.
1、 Medical sewage testing standard
Gb18466-2005 discharge standard of water pollutants for medical institutions
This standard specifies the pollutant control items, discharge and control limits, treatment process and disinfection requirements, sampling and monitoring, and implementation and supervision of standards for medical institutions' sewage, waste gas and sludge produced by sewage treatment stations.
This standard is applicable to the control of sewage, sludge and waste gas discharge from sewage treatment stations, environmental impact assessment, environmental protection facility design, completion acceptance and discharge management after acceptance of medical institution construction projects. When the office area, non-medical living area and other sewage of medical institutions are collected together with the sewage of the ward, the comprehensive sewage discharge shall comply with this standard. For the medical institutions with separate sewage collection system, the discharge of sewage in the living quarters of non ward areas shall comply with the relevant provisions of gb8978.
