Ultraviolet sterilization device for sewage treatment and treatment method thereof

Abstract

The invention discloses an ultraviolet sterilization device for sewage treatment and a treatment method thereof. The ultraviolet sterilization device includes a housing, the lower end of the shell isfixedly connected with a plurality of supporting blocks, and a treatment chamber is arranged in the shell; a liquid inlet is formed in the inner top of the treatment chamber; a liquid outlet is formedin the inner bottom of the treatment chamber; two vertical cavities are symmetrically formed in the shell and located on the two sides of the treatment chamber correspondingly, a rotating rod is rotatably connected between the inner walls of the two sides of the treatment chamber, a sliding rod is fixedly connected between the inner walls of the two sides of the treatment chamber, sliding blocksare arranged on the rotating rod and the sliding rod in a penetrating mode, and a threaded layer is arranged on the rotating rod. When the sterilization device is used, an ultraviolet lamp for sterilization is in a moving state, the sterilization range is enlarged, meanwhile, in the moving process, the surface of the sterilization lamp can be scraped and cleaned, and it is guaranteed that the sterilization lamp is in a high-light-transmission state all the time.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an ultraviolet sterilizing device for sewage treatment and a treatment method thereof. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. In various fields, sterilization treatment is an important process in the sewage treatment process, and now the commonly used sterilization method is to add disinfectant and ultraviolet light sterilization. For the current ultraviolet sterilization device and its treatment method for sewage treatment Say, when using, there are following problems: [0003] The existing ultraviolet sterilizing device and its treatment method generally place the ul...

AI Technical Summary

Problems solved by technology

[0003] The existing ultraviolet sterilizing device and its treatment method generally place the ultraviolet lamp body in the sewage treatment room, and then add the sewage to be treated, but in this process, the lamp body is in a static state, so that the water body and the ultraviolet lamp The contact is not comprehensive enough, so that the sterilization effect is not good, and there are some impurities in the sewage, which will cover the lampshade, so that the light transmission of the lampshade will also be reduced, which makes the sterilization effect worse, so how to solve these problems is what we need to consider
