Medical wastewater exists in health centers, medical institutions and other places. The indicators in these wastewaters must be up to standard before they can be discharged. If not treated carefully, it is very likely to cause environmental pollution. In severe cases, it is not impossible for it to cause harm to the human body. It is essential to do a good job in the online monitoring of medical wastewater to ensure its safe discharge. So, do you know the monitoring indicators for medical wastewater? Have you heard about it? It’s okay if you don’t know. In this chapter, let’s learn about the monitoring indicators of medical wastewater together with me.
When it comes to medical wastewater monitoring, it is an essential task for hospitals, health clinics and other places. As for the monitoring indicators, there are many, specifically including some heavy metals (hexavalent chromium, total silver, etc.), coliform bacteria, total bacterial count, total residual chlorine and other parameters.
Among the several types mentioned above, coliform bacteria, total bacterial count and total residual chlorine are the key monitoring objects. Especially after the outbreak of the epidemic at the end of 2019, the relevant departments paid more attention to the monitoring of indicators such as total residual chlorine and coliform bacteria in hospital wastewater. Especially hospitals with COVID-19 patients should pay more attention.
As for why these two projects need to be closely monitored? In fact, to put it simply, it is to determine the water quality by testing the coliform bacteria and total residual chlorine in the wastewater discharged from hospitals. Coliform bacteria mainly come from human feces. It is explicitly stipulated that the coliform bacteria in water must not exceed a certain index. Once it does, it will cause environmental pollution and thus affect our normal life. Then what about residual chlorine? Disinfectants must be used in large quantities in hospitals, especially during the epidemic, disinfection has become even more common. The chlorine disinfectant used, if the total residual chlorine after disinfection exceeds the specified range, will produce some toxic or carcinogenic substances! Therefore, medical wastewater monitoring must meet the standards and not cause any impact on the environment.
