Ultraviolet disinfection equipment for sewage treatment

Abstract

The invention relates to ultraviolet disinfection equipment for sewage treatment, which comprises a main body and a disinfection lamp, and also comprises an impurity removal mechanism and a cleaning mechanism, the impurity removal mechanism comprises a filter screen, a fixing ring, a driving ring, two fixing assemblies and a plurality of first springs, and the cleaning mechanism comprises a power assembly, a first bearing, a rotating gear and two cleaning assemblies. According to the ultraviolet disinfection equipment for sewage treatment, the impurity removal function of sewage is realized through the impurity removal mechanism, the situation that the penetrating power of a disinfection lamp is reduced due to excessive impurities is avoided, and the situation that the sewage cannot be fully and thoroughly disinfected is prevented, so that the reliability of the equipment is improved. Through the cleaning assemblies, the function of cleaning the inner wall of the main body and the surface of the disinfection lamp is achieved, it is prevented that scale is formed on the surface of the disinfection lamp to block irradiation light of the disinfection lamp, the disinfection effect is prevented from being affected, and therefore the reliability of equipment is improved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an ultraviolet disinfection device for sewage treatment. Background technique [0002] Ultraviolet disinfection is an important process in sewage treatment. In recent years, with the decrease of cost and the control of chlorine and chlorine derivatives, ultraviolet disinfection technology has developed rapidly abroad, and there are also domestic examples of using ultraviolet disinfection to treat urban sewage. [0003] When the existing ultraviolet disinfection equipment performs sewage treatment work, due to the excessive content of impurities in the sewage, the penetrating power of the ultraviolet disinfection lamp will be reduced, so that the sewage inside the main body cannot be fully disinfected, thereby reducing the The quality of disinfection reduces the reliability of the existing ultraviolet disinfection equipment. Not only that, after the existing ultraviolet disinfection...

AI Technical Summary

Problems solved by technology

[0003] When the existing ultraviolet disinfection equipment performs sewage treatment work, due to the excessive content of impurities in the sewage, the penetrating power of the ultraviolet disinfection lamp will be reduced, so that the sewage inside the main body cannot be fully disinfected, thereby reducing the The quality of disinfection reduces the reliability of the existing ultraviolet disinfection equipment. Not only that, after the existing ultraviolet disinfection equipment has been working for a long time, the surface of the disinfection lamp is easy to form scale, thereby blocking the irradiation light of the ultraviolet disinfection lamp, which is harmful to disinfection. work, which greatly reduces the practicability of existing UV disinfection equipment
