Domestic sewage refers to the used water from daily activities (such as face-washing water, vegetable-washing water, etc.), which can, in some cases, be reused. Medical wastewater, on the other hand, is water that has been used and can no longer be reused. This chapter will provide a detailed explanation of the differences between domestic sewage and medical wastewater.
1.What Exactly is Domestic Sewage? If we are talking about heavily polluted wastewater, it primarily comes from water discharged from toilets. In contrast, wastewater from activities like laundry, handwashing, and bathing is relatively easier to treat and recycle. For example, in the design of building water supply and drainage pipelines, most systems combine sewage and wastewater into a single flow. As mentioned above, water from flushing toilets, showering, and handwashing all share the same pipeline. However, it is important to note that kitchen drainage must be separated from toilet drainage.
2.What is medical wastewater? Medical wastewater mainly consists of wastewater discharged from hospital wards, laboratories, operating rooms, and other areas. Its pollution levels are highly complex. This is because hospitals harbor many pathogenic bacteria, viruses, and chemical agents, making the wastewater potentially infectious.
Based on the above two points, it is not difficult to see that the differences between domestic sewage and medical wastewater are significant. One could even say there is little basis for comparison!
The discharge of medical wastewater has a profound impact on water resources and can be described as a “source” of threats to human health. If medical wastewater containing pathogenic microorganisms is discharged without undergoing disinfection or other harmless treatments, it can cause severe pollution to water and soil, leading to various diseases. Therefore, hospitals must have wastewater treatment systems in place. These systems disinfect and sterilize the wastewater before discharge, and water quality monitors are used to conduct real-time testing of various indicators to ensure that all parameters meet standards before the water is released.
It is important to emphasize that conducting Medical Wastewater Online Monitoring is crucial. It allows for timely understanding of changes in various indicators in the wastewater, thereby ensuring the safety of water quality!
