Studies have shown that ultraviolet radiation mainly kills microorganisms by radiating damage to microorganisms (bacteria, viruses, spores and other pathogens) and destroying the function of nucleic acids, thereby achieving the purpose of disinfection. The action of ultraviolet rays on nucleic acids can lead to the breaking of bonds and chains, cross-strand cross-linking and the formation of photochemical products, etc., thereby changing the biological activity of DNA and preventing the microorganisms from replicating themselves. This ultraviolet damage is also a lethal damage.
The ultraviolet light used for disinfection is C-wave ultraviolet light. Ultraviolet sterilization and disinfection is the use of ultraviolet light of appropriate wavelength to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing growth cell death and / or Regenerative cell death, to achieve the effect of sterilization and disinfection. Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics, and uses specially designed high-efficiency, high-strength and long-life UVC band ultraviolet light to irradiate flowing water to expose various bacteria, viruses, parasites, algae and Other pathogens are killed directly.
