Water treatment facility capable of disinfecting by ultrasonic cooperating with ultravioletray

Abstract

The invention discloses a water treatment facility capable of disinfecting by ultrasonic cooperating with ultravioletray. A water inlet and a water outlet which are coaxial are drilled in the middle of the side wall of a drum body outer shell and are symmetrical relative to an axis of the drum outer shell. A rectangular hole is drilled on the side wall of the drum body outer shell and a rinse tank is arranged inside the rectangular hole. Four ultrasonic transducers are distributed along the axial direction of the drum body outer shell in the rinse tank in an equally spaced mode. A quartz sleeve is sleeved in an inner cavity of the drum body out shell in coaxial mode and a medium-pressure ultraviolet lamp is sleeved inside the quartz sleeve. Clean water is filled into the drum body outer shell, the water inlet and water outlet are closed, the medium-pressure ultraviolet lamp and the ultrasonic transducers are in working, and then the water inlet and the water outlet are opened simultaneously so as to enable the clean water to flow into the drum body outer shell after the working of the medium-pressure ultraviolet lamp and the ultrasonic transducers is stable. Next, the medium-pressure ultraviolet lamp and the ultrasonic transducers cooperate with each other to process, and then the medium-pressure ultraviolet lamp and the ultrasonic transducers delay to be closed after processing. Therefore the effect that ultraviolet sterilization is used independently is enhanced to a great extent. Besides, the ultraviolet ray also can keep cleaning the quartz sleeve and the inner wall of the drum body.

Description

technical field [0001] The invention relates to a water treatment device for ultrasonic and ultraviolet sterilizing, which belongs to the field of water treatment. Background technique [0002] Ultraviolet sterilization is a physical water treatment and sterilization method. The principle of ultraviolet disinfection is mainly to use ultraviolet light to destroy the genetic material nucleic acid (DNA or RNA) of microorganisms so that they cannot be split and replicated. In addition, ultraviolet rays can also cause other structures of microorganisms Therefore, the advantages of ultraviolet sterilization are: pure physical disinfection method, simple and convenient, broad-spectrum and high-efficiency, no secondary pollution, easy management and automation. However, the ultraviolet disinfection method can only kill the microorganisms in the outer layer, and cannot inactivate the microorganisms attached to the solid particles or hidden inside the spores. Therefore, when the treat...

AI Technical Summary

Problems solved by technology

However, the ultraviolet disinfection method can only kill the microorganisms in the outer layer, and cannot inactivate the microorganisms attached to the solid particles or hidden inside the spores. Therefore, when the treated water leaves the reactor, some microorganisms killed by ultraviolet light will be revived Under the mechanism, the damaged DNA molecules will be repaired, allowing the bacteria to regenerate

And in the actual application process, due to factors such as poor water quality, high hardness, and large bacterial content, it is easy to scale on the quartz tube wall, resulting in reduced ultraviolet radiation energy and weakened penetrating power, which seriously affects the sterilization effect
