There are various types of patients in hospitals. Various viruses exist in medical wastewater, which refers to the wastewater discharged by hospitals into the natural environment. These wastewater must be treated before being discharged, especially the sewage discharged from some infectious disease wards, which can only be discharged after being disinfected and monitored to meet the standards. Have you learned about the standards for online monitoring of medical wastewater? In this chapter, we will learn about the standards for wastewater discharge from hospitals.
Monitoring standard for medical wastewater: GB18466-2005 “Discharge Standard of Water Pollutants for Medical Institutions”. This standard is applicable to the control of wastewater discharged from hospitals, as well as the management issues related to environmental impact assessment of medical wastewater monitoring projects and the design of environmental protection facilities. It is also when the wastewater from the hospital office area and the non-medical living area is collected together that the comprehensive wastewater discharge standards should be followed. In addition, for medical institutions that have established a separate wastewater collection system, the discharge of wastewater from their living areas complies with the relevant provisions of GB8978.
What are the main items to be tested for the wastewater discharged from hospitals? It depends on how you classify it. For instance, the monitoring items for medical wastewater from infectious diseases include heavy metals, coliform bacteria, total bacterial count, COD, BOD, color, volatile phenols, total residual chlorine, etc. If it is a project for monitoring medical wastewater in comprehensive medical institutions, it will be relatively fewer than the above ones, but the basic COD, pH, heavy metals, coliform bacteria, and total residual chlorine are all the same.
Overall, the requirements vary by region. Therefore, it is still necessary to decide which online water quality testing equipment to use based on the requirements of the review department.
