Some people may ask that at the end of 2019, when the epidemic emerged, major hospitals attached great importance to disinfection and the monitoring of medical wastewater. So, was it because of the epidemic that disinfection and water quality monitoring work were carried out? Of course not! Disinfection and monitoring of medical wastewater is an essential task that cannot be omitted! Why?
A hospital is a place with a large and complex flow of people, with various patients coming and going, including those with infectious diseases and so on. As a result, medical wastewater will contain a large amount of pathogenic bacteria, viruses, chemical agents and other harmful substances, all of which need to go through special processes before being discharged. When it comes to disinfection, hypochlorous acid is a commonly used disinfectant in hospitals. The total residual chlorine content in hospital wastewater can reflect the content of bacteria and viruses in the water. Then, based on the relevant medical wastewater discharge standards in China, it can be determined whether the wastewater can be safely discharged. Once hypochlorous acid is used to disinfect the water quality, it is also necessary to ensure that the total residual chlorine content in the wastewater meets the standard. The RCl900 Total Residual Chlorine Online Analyzer can be used to monitor the total residual chlorine in the water in real time to see if the total residual chlorine in the wastewater exceeds the standard. All the harmful substances have been eliminated, but the residual chlorine still causes harm to the body or the ecological environment.
The process of detecting residual chlorine is as follows: First, an analyzer is used to measure the total residual chlorine content in the water. Then, the detection data is transmitted in real time to the corresponding platform through wireless communication. By analyzing the data, the discharge indicators of medical wastewater can be efficiently determined, ensuring the safety of water quality discharge!
So, if disinfectants are used, does that mean other indicators in the wastewater can be ignored? Of course not! It is also necessary to carry out real-time detection to determine whether it exceeds the standard. Only after confirming that it exceeds the standard can it be dealt with. This can achieve the effect of “treating the symptoms and the root cause”. The online monitoring project for medical wastewater includes not only total residual chlorine but also coliform bacteria, pH, BOD, suspended solids, etc.
