It is understandable that a large amount of medical wastewater is produced in hospitals. So how will these wastewater be treated? Where is it discharged to again? What harm would be caused if it were discharged directly without treatment?

The treatment of medical wastewater is a topic of great concern to all of us. This is because medical wastewater comes from various departments, including examination rooms, laundries, operating rooms and other different places. The pollutants contained in these wastewaters include pathogenic microorganisms, BOD, COD, toxic and harmful physical and chemical pollutants, etc. It not only has an impact on the ecological environment, but also causes great harm to human health. Therefore, it is essential to do a good job in the online monitoring of medical wastewater. No matter which indicator is not up to standard, it must not be discharged.

So Where Will These Medical Wastewater Be Discharged To?

One of the common things done in hospitals is to use chlorine disinfectants for disinfection. Also, hospitals usually have supporting sewage treatment facilities and treatment facilities, among which the disinfection of septic tanks is very important. After disinfection, these medical wastewater will be sent to the sewage treatment plant for processing, and the water quality will be monitored in real time. Only after confirming that there are no issues can it be ruled out or used again.

In addition, it should be noted that in the monitoring of medical wastewater, apart from the common online analyzer for coliform bacteria, the monitoring of total residual chlorine cannot be ignored! Although chlorine disinfectants are used for disinfection and sterilization, only the amount of chlorine used is determined by the amount of pollutants present. This may result in total residual chlorine, and once it exceeds the standard, it can produce toxic or carcinogenic substances! Therefore, it is essential not to forget the real-time monitoring of total residual chlorine in medical wastewater.
