There are many pollutants in medical wastewater, including viruses, bacteria, infectious bacteria and other harmful substances. Therefore, it is strictly prohibited to discharge medical wastewater without meeting the standards to avoid secondary pollution. Here, we will focus on the management of medical wastewater discharge.
In fact, the environmental protection department has already made requirements, coordinating and cooperating well among health and drainage departments. They urge relevant medical institutions to classify and treat the wastewater and ensure stable and compliant discharge. If some medical wastewater treatment facilities or sewage treatment capacities are insufficient, they can urge the construction of temporary sewage treatment tanks based on local conditions to ensure the disinfection of medical wastewater and strictly prohibit the discharge of medical wastewater without meeting the standards.
In the past two years, due to the impact of the epidemic, relevant departments have been more strict in strengthening the compliance discharge of medical wastewater. Especially for some hospitals that have treated patients with COVID-19 and some temporary isolation points, the wastewater must undergo disinfection and sterilization work to ensure that the indicators in the wastewater are qualified for discharge. Clearly define the emergency treatment of virus-contaminated medical wastewater, strictly prevent pollution spread, strengthen disinfection and sterilization, and use chemical agents for disinfection treatment, etc.
To ensure that the indicators of medical wastewater are discharged in compliance, the treatment should be done well with disinfection. The Medical Wastewater Online Monitoring is also very important. This work can help you clearly understand the content of various indicators in the wastewater and whether they exceed the safety standards. For the monitoring indicators of medical wastewater, coliform bacteria, coliform bacteria, total colony count, etc. must be tested. Also, when disinfecting the wastewater, the amount of disinfectant should be controlled well. For example, using chlorine-containing disinfectant to disinfect the wastewater, and installing an RCl900 Total Residual Chlorine Online Analyzer to monitor the total residual chlorine in the water, controlling the content of total residual chlorine to avoid unnecessary harm! In addition to the above indicators, there are also some routine indicators, such as COD, total phosphorus, ammonia nitrogen, etc., which must meet the standards before discharge.
