For medical wastewater, its source is very complex, containing many pathogenic microorganisms, viruses, and some harmful pollutants, etc. If it is directly discharged without treatment, it will cause severe pollution to the water source. At this time, the treatment of medical wastewater becomes very important. Then, what about the management system related to it? The management systems for different treatment methods will also be different. This article will explore the management system issues regarding the process treatment of medical wastewater and the Medical Wastewater Online Monitoring.
The functions, facilities, and staff composition of different departments in hospitals are different, and the composition and volume of wastewater produced are also different. Moreover, the wastewater produced by different hospitals also vary greatly. The main sources of wastewater are wards, laundry, isotope treatment and diagnosis rooms, operating rooms, laboratories, etc., including domestic sewage, canteen, dormitory drainage, etc.
How much Medical Wastewater is Generated by the Hospital?
1.If it is a large hospital with comprehensive facilities, on average, it generates 400-600L/(bed.d) per day, K = 2.0-2.2;
2.For a general hospital, compared to a large one, it will be better, at 300-400/(bed.d), K = 2.2-2.5;
3.For a small hospital, it will be even less, mainly at 250-300L/(bed.d), K = 2.5;
What are the Characteristics of Medical Wastewater? The Following can be Understood Through three Categories!
1.Regarding Pathogenic Microorganisms and Their Control Indicators:
In medical wastewater, coliform bacteria is a biological indicator for measuring water pollution by feces (it can be detected and analyzed by the WECT-900 coliform bacteria online analyzer to see if it meets the standard). The diseases mainly transmitted through water in hospital medical wastewater and domestic sewage are intestinal diseases!
2.Water Quality Indicators of Some Toxic and Harmful Substances:
- COD and BOD, these two harmful substances mostly come from the drainage of the living system, and their biodegradability is good, but the disinfectants used by hospitals are not conducive to the treatment of organisms;
- Total mercury, this type of pollutant includes organic, inorganic, and suspended mercury, etc., and is highly toxic, causing poisoning in the human body. It mainly comes from the dental department, broken thermometers, etc.;
- SS, wastewater also has SS, which will affect the appearance of the water body and the disinfection and inactivation effect of chlorine;
- pH, for some acid-base pollution in hospitals, it mainly comes from disinfectants in the laboratory, laundry, laboratory, etc., which will corrode the pipes or affect the disinfection effect;
- The hazards of animal and plant oils, mainly from the drainage of the canteen, will affect the dissolved oxygen in the water body and the disinfection effect of medical wastewater.
