Why is it important to be familiar with the knowledge of medical wastewater? In fact, it is also to avoid some unnecessary harm! Whether it is for human health or the ecological environment, understanding one of the knowledge points about medical wastewater, such as online monitoring of medical wastewater, is also very important! However, in this chapter, the main purpose of the author is to understand the hazards and characteristics of medical wastewater together with everyone.

When it comes to medical wastewater, compared with industrial wastewater, the harm of medical wastewater is obviously much greater. During the operation of hospitals, wastewater with direct or indirect infectivity, toxicity and other hazards is produced. The components inside are very complex and involve many different kinds of pollution. Among them, apart from pathogens such as bacteria and viruses, there are also chemical reagents and radioactive isotopes. It has characteristics such as spatial pollution, acute infection and latent infection. The harm can be imagined! If this water is discharged directly into the sewer without treatment, it will cause pollution to water and soil, which will lead to various diseases and thus pose a great threat to people’s health!

In addition, the volume of medical wastewater is closely related to the scale of the hospital. The amount of wastewater is large in summer throughout the year. What the staff need to do is not to prevent the wastewater from being discharged, but to monitor and treat it. Only after confirming that all indicators are qualified can it be discharged!
