We should be aware that medical wastewater contains a large amount of harmful and infectious viruses, etc. It is definitely necessary to undergo water treatment monitoring to ensure there are no issues before it can be discharged. This article will take chlorination disinfection pretreatment as an example to clarify the requirements for medical wastewater treatment and monitoring. It can be explained from the following points:
1.The water quality of the treated medical wastewater must meet the relevant standards. For specific standards, you can refer to the local monitoring company.
2.Remember! The retention time of wastewater in septic tanks must not be less than 36 hours.
3.If the wastewater is disinfected by chlorination, attention should be paid to the amount of chlorine, and an appropriate amount should be added according to the water treatment situation.
4.The standards for sewage treatment: The contact time of the disinfection contact tank should be no less than one hour, and the total residual chlorine at the outlet of the contact tank should be between 2 and 8mg/L.
5.While applying chlorine-containing disinfection, it is also necessary to pay attention to the residual chlorine content in the water. Use an online total residual chlorine analyzer to monitor the residual chlorine in the water in real time and observe to ensure that it does not exceed the specified standard; otherwise, it will also cause certain harm.
6.Additionally, what specific items are included in the online monitoring of medical wastewater? Apart from the total residual chlorine mentioned above, there are many other indicators that need to be monitored. For instance, coliform bacteria mainly come from human feces and are discharged through sewers. If their content exceeds the standard, it can also be harmful to the human body. Therefore, it is very important to conduct regular coliform bacteria tests. Salmonella, Shigella and other bacteria also need to be tested, and no pathogenic bacteria should be detected. There are also some routine items such as pH value and COD that need to be detected in real time to ensure the safety of medical wastewater discharge!
