Background

With the development of the times, the attention of people on the water quality of drinking water is continuously increased. Since the sterilization of water is an important step in improving the quality of water, methods and methods for sterilizing water are also being continuously tried and improved.

At present, a certain amount of liquid chlorine is generally put into a water body, so that the sterilization process of the water body is realized, but after the sterilization process of the water body is realized by using the liquid chlorine, chemicals such as the liquid chlorine and the like can change chemical components of the water body, so that secondary pollution is formed on the water body; meanwhile, a certain amount of chloride residues still exist in the water body, so that the water body has a certain pungent smell. The ultraviolet sterilization is to use ultraviolet with proper wavelength to destroy the molecular structure of DNA or RNA in the organism cells of the microorganism, so as to cause the death of growing cells and/or regenerative cells, thereby achieving the effect of sterilization and disinfection. Therefore, the process of sterilizing the water body by using the ultraviolet sterilization does not generate secondary pollution and has no problem of chemical residue, and the method for sterilizing the water body by using the ultraviolet is gradually popularized and applied.
