Introduction

The ultraviolet bactericidal wave band is mainly between 200-300nm, and the bactericidal ability of 253.7nm wavelength is the strongest. When various bacteria and viruses in the water or air pass through the ultraviolet (253.7nm wavelength) irradiation area, Ultraviolet light can penetrate microorganisms and their nuclei, destroys the molecular bonds of nucleic acids (DNA or RNA), and causes them to lose their replication ability or lose their activity and die. So as to kill all bacteria and viruses without using any chemicals. The germicidal lamp does not need to be converted into visible light, and the wavelength of 100-200nm can play a good sterilization effect. This is because there is a law for the absorption spectrum of light waves. The ultraviolet rays at 100-200nm have the maximum absorption and are absorbed. Ultraviolet rays actually act on genetic material, namely DNA. It plays a kind of actinic effect. The energy of ultraviolet photons is absorbed by base pairs in DNA, causing genetic material to mutate, causing bacteria to die immediately or unable to reproduce offspring, achieving sterilization. purpose.
