Ultraviolet sterilization belongs to a pure physical disinfection method, has no secondary pollution, and is widely applied to the fields of water treatment and air purification. The combination of ultraviolet ray and ozone has strong oxidizing and decomposing capacity, and can produce superimposed effect and play a strong role in water treatment and air purification treatment. The current commonly used dual-band ultraviolet lamp tube is generally composed of two lamp tubes, wherein the tube wall of one lamp tube can transmit 253.7nm ultraviolet rays, and the tube wall of the other lamp tube can transmit 184.9nm ultraviolet rays. That is, two lamps having a wavelength of 184.9nm and a wavelength of 253.7nm were used and ultraviolet rays having a short wavelength of 184.9nm and a medium wavelength of 253.7nm were obtained.

In use, the mercury atoms in each tube are excited to produce a characteristic mercury spectrum which transmits ultraviolet radiation through the different walls at 253.7nm and 184.9nm, respectively. Wherein, ultraviolet rays with the wavelength of 253.7nm are easily absorbed by organisms, act on genetic material DNA of the organisms, and damage the DNA to cause bacterial death; ultraviolet rays with the wavelength of 184.9nm combine with oxygen molecules in the air to generate ozone with strong oxidizing property, and ultraviolet rays with the wavelength of 253.7nm further decompose ozone and water molecules to form hydroxyl radicals.
