Hospital sewage treatment is an environmental protection problem that medical institutions must face, which not only involves environmental pollution, but also is closely related to medical safety.
In order to achieve efficient treatment and disinfection of wastewater, ultraviolet technology is widely used in hospital wastewater treatment.
Ultraviolet disinfection technology refers to the method of killing bacteria, viruses and other microorganisms in water by using the strong oxidation and sterilization ability of ultraviolet rays.
Compared with traditional chemical disinfection, ultraviolet disinfection has the advantages of no secondary pollution, safety and reliability, and has become an environmentally friendly and efficient treatment method.
In hospital wastewater treatment, the selection of ultraviolet disinfection systems is very important.
The following is an in-depth analysis of the selection of ultraviolet disinfection of hospital sewage from three aspects:
1.Device Selection:
Hospital sewage ultraviolet disinfection equipment should choose products with high energy ultraviolet output and stable performance.
In this way, we can ensure that ultraviolet rays can fully irradiate the microorganisms in the sewage, kill their cell structure, and avoid secondary pollution.
At the same time, the equipment should also have an automatic control and monitoring system, which can monitor the ultraviolet disinfection effect and equipment operation status in real time to ensure the disinfection effect and the safe operation of the equipment.
2.Device Layout:
Hospital sewage treatment usually needs to consider the characteristics of dispersed sewage ** and large fluctuation of flow.
Therefore, the layout of ultraviolet disinfection equipment needs to be reasonably planned according to the actual situation.
Generally speaking, UV disinfection equipment can be distributed in different treatment stages or key locations according to factors such as the location of sewage entering the system, the layout of the pumping station, etc., to maximize sterilization and disinfection.
3.Operation & Maintenance:
The operation and maintenance of hospital sewage treatment equipment is very important, which is directly related to the stability of disinfection effect and the extension of equipment life.
For ultraviolet disinfection equipment, the light source and reflector should be cleaned regularly to maintain their output effect
Regularly inspect the control system and monitoring instruments to ensure that they are working properly.
In addition, it is also necessary to establish a sound management system, regularly maintain and record disinfection equipment, and find and solve equipment problems in a timely manner.
Ultraviolet disinfection technology has a broad application prospect in hospital sewage treatment.
In addition to hospital sewage treatment, it can also be applied to urban sewage treatment, drinking water disinfection and other fields.
Therefore, the selection, operation and maintenance of ultraviolet disinfection equipment are very important.
Only by rational selection of equipment, scientific layout and standardized operation can we ensure that hospital sewage is effectively treated, reduce environmental pollution and ensure medical safety.
