Hospital wastewater refers to the hospital to the natural environment or urban pipeline discharge of wastewater, but this water is not monitored and treated after the exclusion is certainly not possible, the main pollutants in the hospital wastewater are: pathogens (parasite eggs, pathogens, viruses, etc.), organic matter, suspended matter and so on. But the above does not say residual chlorine, then why the hospital wastewater online monitoring project must detect residual chlorine?Please Look Below:

As mentioned above, a large number of bacteria in the main pollutants, we must be treated before we can discharge the water, we must use disinfectant. The commonly used disinfectant for wastewater disinfection is chlorine-containing disinfectant, the content of disinfectant remaining in water is inversely proportional to bacteria, that is, how much bacteria will be left behind, but the bacterial content is high, the disinfectant will certainly not be less, but if on the contrary, the disinfectant remaining is more, it means that the bacteria is relatively less, China also has a standard for the total residual chlorine content of wastewater discharge. Do not exceed the standard!

But there is still a question, will it be said that all the disinfectants put in have been consumed, and there is no need to monitor the total residual chlorine? When you add too little disinfectant, it is not possible to monitor the presence of excess chlorine, but it is also very likely that the disinfectant is used up and the bacteria still exist, if it is so direct discharge is certainly not possible, all in the addition of how much disinfectant is also to calculate the line, and in order to discharge water quality safety, the residual chlorine in the hospital wastewater must be monitored! RCl900 Total Residual Chlorine online analyzer is a fully automatic online monitoring instrument controlled by an embedded system. After the water sample and anti-interference agent are automatically injected into the reactor, the characteristic color developing agent is automatically added for color developing reaction, and the absorbance of the reactants is measured. The online analyzer can directly measure the total residual chlorine content in water through the absorbance value.
