Ultraviolet is a kind of light invisible to the naked eye, which can be subdivided into UVA (315~400nm) UVB (280~315nm) UVC (200~280nm) according to different wavelengths. UVC is easily absorbed by DNA (ribonucleic acid). UV disinfection system uses UVC. Ultraviolet sterilization equipment It integrates optics, microbiology, mechanics, chemistry, electronics, fluid mechanics and other comprehensive disciplines. The water is irradiated by the strong ultraviolet C light produced by the specially designed ultraviolet C light generator with high efficiency, high intensity and long life. When bacteria, viruses, algae and other organisms in the water are exposed to a certain amount of ultraviolet C light (wave light 253.7 nm), their DNA and RNA structures are destroyed, and cell regeneration cannot be carried out, so as to achieve the purpose of water disinfection and purification.

Ultraviolet sterilization system: Ultraviolet sterilization principle: Ultraviolet Sterilization equipment Integrating optics, microbiology, mechanics, chemistry, electronics, fluid mechanics and other comprehensive disciplines, the strong ultraviolet C (UVC) produced by the specially designed high-efficiency, high-strength and long-life ultraviolet sterilization device is used to irradiate the water flow. When bacteria, viruses, algae and other organisms in the water are exposed to a certain amount of UVC (wavelength 254nm), their DNA and RNA structures can no longer be carried out, Bacteria and viruses lose the ability of self replication, so as to achieve the purpose of water disinfection and purification.

Microwave electrodeless ultraviolet sterilization equipment It is mainly used for sterilization and disinfection of sewage, water supply, reclaimed water, surface water, pure water, purified water, landscape water, swimming pool water, seawater and other water quality and air. The ultraviolet sterilization system has the advantages of spectrum sterilization, fast sterilization, high sterilization efficiency, environmental protection and safety, no secondary pollution, low operation and maintenance freight, small floor area, etc.

Relevant factors affecting the effect of ultraviolet disinfection in reclaimed water reuse equipment:

Treated water volume: the average flow and the flow change coefficient have an important impact on the treatment effect.

External water quality: turbidity, suspended solids concentration and particle size

UV dose: product of UV radiation intensity and exposure time, expressed in mWs/cm2: upstream treatment process/UV penetration

Ultraviolet sterilization advantages:

● Broad spectrum sterilization, which works on almost all bacteria, viral microorganisms and algae;

● Fast sterilization and high sterilization rate;

● Environmental protection, safety, no secondary pollution, pure physical sterilization, no toxic and side effects;

● Low operation and maintenance cost, compact structure and small floor area;

● Continuous large flow disinfection, fast and simple installation, easy maintenance.

ultraviolet rays Sterilization equipment Its advantages can be shown in high efficiency, low cost, pollution-free, long service life, etc.
