Technical Field

The invention relates to the technical field of water purification, in particular to a large-caliber overflowing type water purification and disinfection device.

Background

Water is an essential substance for people in production and life, and the purification of water is becoming more and more important, so that the disinfection treatment of water is particularly important. After the water body is coagulated or filtered, the microorganisms in the water body are not completely inactivated although the microorganisms are greatly reduced. In the prior art, the following means are generally adopted for disinfecting domestic water: 1. physical methods such as ultrasonic sterilization, heating, etc.; 2. the chemical method comprises the following steps: chlorine adding method, ozone method, heavy metal ion method and other oxidant methods. However, the heating method and the ultrasonic wave sterilization have a limited range of action, and chemical substances in the chemical method have negative influence on the environment, including water toxicity, organic chlorine danger, chlorine resistance of viruses and protists, and the like. In contrast, the ultraviolet disinfection mode for water purification, especially the deep ultraviolet disinfection, has good effect and does not produce disinfection by-products, and the like, and is valued by people.

The dynamic direct drinking water deep ultraviolet LED sterilizer with the bulletin number of CN 104016443B discloses a dynamic direct drinking water deep ultraviolet LED sterilizer, which comprises a water inlet assembly, a water outlet assembly, a sterilization assembly and a deep ultraviolet LED module, wherein a deep ultraviolet LED is adopted as a luminous source, the area of a point irradiated by the deep ultraviolet LED module has high light intensity and no poison is generated, and the high-efficiency sterilization of dynamic water is realized; the publication No. CN 103570098A, namely 'an ultraviolet LED fluid disinfection system', discloses an efficient fluid disinfection treatment system integrated with a deep ultraviolet LED chip, aiming at the defects that ultraviolet spectrum radiation distribution is uneven and the effect of the deep ultraviolet LED chip is reduced, a deep ultraviolet LED component is adopted to generate ultraviolet light with an efficient disinfection function, the ultraviolet light can effectively penetrate through a transparent pipeline and disinfect fluid in the pipeline, and reflective materials with an ultraviolet reflection function are coated on the inner surface and the outer surface of the pipeline so as to reflect ultraviolet light emitted and transmitted by the deep ultraviolet LED in the pipeline. The publication CN 109395118A discloses a method for disinfecting flowing fluid by using deep ultraviolet rays and a disinfector for disinfecting flowing fluid, aiming at the defect that the current fluid disinfection technology suffers from UV energy loss due to the solid-liquid surface between the fluid to be disinfected and the device containing the fluid, the flowing fluid with the side wall wrapped by the fluid medium and contacted with the fluid medium is generated, and ultraviolet light is emitted into the flowing fluid column along the axial direction, so that the UV energy loss is reduced, and the disinfection effect of the flowing fluid such as water, beverage or medical fluid is improved.

However, in practice, it has been found that if the ultraviolet water purification technology is adopted to treat a large flow of fluid, the radiation source can sterilize a single area, that is, the radiation source can sterilize the whole area, and such an arrangement cannot meet the disinfection treatment of the large flow of fluid. In order to solve the above problems, a new technical means is needed.
