Problems solved by technology

However, whether it is a low-pressure mercury lamp or an ultraviolet light-emitting diode, when the ultraviolet light is transmitted from the air to the water body, it will be lost due to reflection at the junction of the air and water (water surface), which will weaken the ultraviolet light that actually enters the water body.
In addition, the radiation range of ultraviolet light in water is very limited. If a large-scale water body is to be disinfected, a large number of ultraviolet lamps must be installed accordingly, which will increase the treatment cost.
At the same time, the existing process can only sterilize the area exposed to ultraviolet light, and the area that cannot be irradiated by ultraviolet light has no disinfection effect, resulting in disinfection "dead spots" remaining in the sterilized space
In order to enhance the disinfection effect and reduce the "dead angle" of disinfection, the usual practice is to set up ultraviolet lamps for various parts of the water body, which increases the disinfection cost but does not significantly improve the disinfection effect
At the same time, the existing ultraviolet lamp does not have any degradation effect on the toxic organic matter suspended in the water body, and the killing effect on viruses, which are simple in structure and have no organelles, needs to be improved urgently

Abstract

The invention discloses a water sterilization system for ultraviolet light-emitting diodes, which comprises an ultraviolet light-emitting diode module and a photocatalytic assembly, wherein the ultraviolet light-emitting diode module can produce ultraviolet light; the photocatalytic assembly comprises at least a photocatalytic plate of which the obverse side faces the ultraviolet light-emitting diode module; and the obverse side of the photocatalytic plate is covered with a nano titanium dioxide catalytic layer. The sterilization system disclosed by the invention is reacted with oxygen and water in a water body so as to produce carboxyl free radicals with high reactivity and super-oxygen ions with strong oxidability. The carboxyl free radicals and the super-oxygen ions are diffused in the water body required to be sterilized, and through the oxidation of proteins and genetic materials of pathogens, the pathogens are inactivated, so that the spatial no-dead-corner thorough sterilization is realized.

Description

technical field [0001] The invention relates to the technical field of ultraviolet light disinfection, in particular to an ultraviolet light-emitting diode water disinfection system. Background technique [0002] Ultraviolet light is a commonly used disinfection equipment, which can effectively kill bacteria, viruses, spores and other pathogens in the air and on the surface of tools. It is widely used in the disinfection and sterilization of households, medical institutions, sterile rooms and other spaces. But existing. Most of the existing ultraviolet lamps are low-pressure mercury lamps, which have short service life, high energy consumption and low light intensity. Ultraviolet light-emitting diodes have the advantages of long service life, high light intensity, and low energy consumption, and are widely used in the field of disinfection. There is an existing technology for disinfecting water with ultraviolet lamps. The specific method is to irradiate water bodies with u...
