Sewage is generated wherever people live, and such wastewater needs to be treated in light of actual conditions. Direct discharge will lead to severe water source pollution. Therefore, Sewage Monitoring work must be equally valued in schools.
There are thousands of schools across China, inhabited by students, teachers and other staff members. Water consumption on campus inevitably produces wastewater. Besides domestic sewage, laboratories and school-run factories also discharge polluted wastewater. Campuses feature large and dense crowds, resulting in a high volume of domestic sewage. In addition, laboratory wastewater contains chemical contaminants, whose combined pollutants will aggravate environmental damage to campus water bodies. For this reason, relevant authorities mandate that all sewage must undergo disinfection prior to discharge. Online Water Quality Monitors shall be deployed to conduct real-time detection of various sewage indicators, and discharge is only permitted after all parameters meet the prescribed standards.
Targeted solutions are essential to properly carry out campus sewage monitoring. Below is a brief overview of relevant practices.
Similar to hospitals, schools are classified as special venues. Dedicated environmental monitoring plans are formulated for campus sewage discharge, integrating the monitoring merits of both industrial wastewater and domestic sewage. The first step is to test the levels of organic matter, bacteria and microorganisms in the wastewater. After data collection, the monitoring system platform classifies sewage by pollution severity (heavy pollution or moderate pollution) to facilitate targeted treatment. Importantly, secondary water quality monitoring is required post-treatment to verify whether all water indicators comply with discharge standards. Only certified clean water can be released into the natural environment, preventing unnecessary harm to aquatic organisms and human beings.
It should be noted that Online Water Quality Monitoring Equipment manufactured by Hangzhou Modi relies on qualified water samples for normal operation. The instruments cannot generate accurate readings if water samples contain excessive sediment or turbidity, a key point all users need to bear in mind.
