Introduction to UV Disinfection

The ultraviolet sterilization band is mainly between200－300Between them, among them253.7nmThe wavelength has the strongest bactericidal ability. When various bacteria and viruses in water or air are exposed to ultraviolet radiation（253.7nmWhen the wavelength is irradiated, ultraviolet rays penetrate the cell membrane and nucleus of microorganisms, damaging nucleic acids（DNAperhapsRNA）The molecular bonds make it lose its replication ability or activity and die, thereby killing all bacteria and viruses in water or air without using any chemical drugs. Ultraviolet disinfection and sterilization technology is internationally recognized90The latest generation of disinfection technology that emerged at the end of the decade.Compared to other forms of disinfection, ultraviolet disinfection has the following advantages　

1、Efficient sterilization:

UV sterilization of bacteria and virusessendIt usually takes one to two seconds to achieve99%－99.9%Sterilization rate.

2, highBroad spectrum bactericidal effect:

The broad-spectrum of ultraviolet sterilization is the highest. It can efficiently kill almost all bacteria and viruses.

3、no secondary pollution:

UV sterilization does not add any chemical agents, so it does not cause secondary pollution to water bodies and the surrounding environment. Do not change any components in the water.

4、Safe and reliable operation: Traditional disinfection techniques such as using chlorides or ozone, whose disinfectants themselves are pollutants
