After the treatment of medical wastewater, monitoring various microorganisms in the water is essential. The purpose is to ensure that all indicators meet the standards before the discharge of medical wastewater, thereby preventing severe water pollution.
During the COVID-19 pandemic, organic matter and suspended solids in water were able to adsorb the virus, providing protection for its survival. Additionally, medical wastewater containing feces, which carries the COVID-19 virus, is discharged to wastewater treatment plants, potentially putting wastewater treatment workers at risk of infection. Therefore, it is crucial for relevant institutions, such as medical facilities, wastewater treatment organizations, and water environment monitoring departments, to prevent the transmission of the virus through wastewater. During this period, relevant authorities must strictly enforce the “Discharge Standard of Water Pollutants for Medical Organizations” in hospitals and related institutions. Moreover, they should conduct medical wastewater online monitoring in accordance with operational team requirements to ensure the stable and compliant discharge of medical wastewater.
The indicator for evaluating whether microbial parameters meet the standards is the coliform group. Real-time monitoring of coliform groups in medical wastewater can be achieved using an online coliform analyzer. This is because there is a certain correlation between the coliform count in wastewater and the presence of enteric pathogenic bacteria. When the coliform count in water exceeds 1,174 per liter, pathogenic bacteria can be detected in the wastewater. Thus, monitoring coliform groups can serve as an indicator to control these microorganisms.
There are various methods for monitoring coliform groups, and the standards for coliform groups differ across fields, types of pollution, and monitoring methods. The water quality monitoring instrument for coliform groups produced by Hangzhou Mudi uses the enzyme substrate method, enabling fully automated online monitoring of coliform levels in water.
