Disinfection is a routine practice in hospital settings, encompassing both daily operational processes and wastewater treatment workflows. Healthcare personnel are required to conduct rigorous monitoring of disinfection and sterilization protocols to ensure the safe discharge of wastewater.

In hospitals, epidemic prevention work including disinfection, sterilization, medical waste disposal and medical wastewater treatment must never be relaxed. It is essential to monitor the disinfection and sterilization effect of medical wastewater. Medical Wastewater Monitoring can be adopted to conduct real-time detection of various wastewater indicators. Qualified test results confirm the completion of disinfection and sterilization.

A critical consideration during disinfection and sterilization operations is the need for real-time monitoring of total residual chlorine when chlorine-based disinfectants are employed, to mitigate the risk of “over-disinfection.” Notably, Chinese regulatory authorities have formulated standardized criteria for parameters such as coliform bacteria, total residual chlorine, and other relevant indicators, and strict adherence to these standards is mandatory for all wastewater discharges.

Both routine hospital disinfection and medical wastewater disinfection operations must be executed in strict accordance with standards prescribed by relevant authorities to ensure thorough disinfection. Supervision and inspection initiatives can enhance the operational efficiency, infection control measures, and management practices of healthcare institutions, thereby effectively preventing and controlling iatrogenic infections while ensuring regulatory compliance in wastewater discharge.

Regarding water quality monitoring equipment utilized in hospitals: in addition to conventional monitoring devices for parameters such as chemical oxygen demand (COD), total phosphorus, total nitrogen, and ammonia nitrogen, two critical instruments—the Online Total Residual Chlorine Analyzer and the Online Coliform Group Analyzer—play a pivotal role in Medical Wastewater Monitoring.
