In fact, the pollutants in sewage in different industries will be different, but it is not a single. And hospital sewage can not only E. coli this indicator, can only say that it is one of the important indicators of water quality monitoring. Therefore, it is not enough to monitor the index of E. coli in hospital sewage.
Of course, having said that, E. coli must be monitored! The WECT-900 Escherichia coli online analyzer produced by Hangzhou Mouli Technology uses the enzyme substrate method, the principle that the light signal changes directly after the reaction between the enzyme and the bacteria culture, so as to reflect the total amount of bacteria or the total content of coliform bacteria in the sample. The characteristics of the water quality analyzer are simple operation, automatic operation in the working process, reliable operation, real-time monitoring of the whole reaction process, and dynamic display of the reaction curve of the test item.
If It is not Enough to Monitor Hospital Sewage for E. coli, What Data Should Be Tested?
In the hospital, the sewage produced by different departments is different. So there’s no absolute answer. Take this opportunity to briefly introduce a common indicator monitoring.
Total residual chlorine: We know that residual chlorine refers to the water after chlorination disinfection, contact after a certain time, the remaining effective chlorine in the water, this total residual chlorine reflects the situation of sewage disinfection. However, the total residual chlorine is excessive, which can irritate the eyes, nose, throat and respiratory tract. So be sure to pay attention to the total residual chlorine content in the water to ensure the safety of the water! The total residual chlorine in sewage was detected by RCl900 total residual chlorine online analyzer. When the water sample and anti-interference agent are automatically injected into the reactor, the characteristic color developing agent is added to carry out the color developing reaction, and the absorbance of the reactant is measured. The absorbance value can then be used to detect the total residual chlorine content of the water by the online analyzer. To judge whether qualified!
There are also some conventional, PH, COD, suspended solids, ammonia nitrogen and so on. These indicators are to be tested. I’m not going to say it here. As for the specific indicators that need to be tested, it still depends on the situation.
