Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to an AOT ultraviolet sterilizer for sewage treatment. Background Art
[0002] At present, AOT ultraviolet sterilizer is an ultraviolet sterilizer that is used for disinfection in hot water systems. It uses a special ultraviolet lamp to irradiate the titanium dioxide coating, and then uses the hydroxyl free radicals it produces to decompose bacteria, viruses and organic microorganisms in the water. Conventional low-pressure ultraviolet sterilizers cannot be used in hot water systems because the high temperature will produce scale, which will prevent ultraviolet light from penetrating and affect the sterilization efficiency of ultraviolet rays. The special lamp tube used by AOT has a stable output in hot water. This lamp tube not only produces 235.7 ultraviolet light, but also excites the nano-TiO2 coating photocatalyst to produce highly oxidizing hydroxide, that is, hydroxyl free radicals, which will decompose high-molecular organic matter into small-molecule compounds to generate water and carbon dioxide, which greatly improves the disinfection efficiency.
[0003] The prior art authorization announcement number is: CN214841697U, and the name is a UV sterilizer for a household air source hot water system, which includes an outer shell, an inner shell, an insulation layer filled between the outer shell and the inner shell, and a water inlet joint and a water outlet joint extending to the outside of the outer shell. A quartz sand tube is provided in the middle of the inner shell, and an ultraviolet lamp is provided in the quartz sand tube. The patent has the characteristics of high sterilization stability and good heat preservation effect;
[0004] However, scale will accumulate during the use of this patent, and if it is not cleaned for a long time, the disinfection effect will be reduced, affecting the output, and the residual bacteria in the water will affect subsequent use.
