An ultraviolet sterilizing device for sewage treatment and its treatment method

Abstract

The invention discloses an ultraviolet sterilizing device for sewage treatment and a treatment method thereof, which comprises a casing, a plurality of support blocks are fixedly connected to the lower end of the casing, a processing chamber is arranged inside the casing, and a processing chamber is disposed inside the casing. The top is provided with a liquid inlet, the inner bottom of the processing chamber is provided with a liquid outlet, and two vertical cavities are symmetrically arranged in the housing, and the two vertical cavities are respectively located on both sides of the processing chamber. Rotating rods are connected between the inner walls on both sides of the treatment chamber, and sliding bars are fixedly connected between the inner walls on both sides of the treatment chamber. The rotating rods and the sliding rods are provided with sliders, and the rotating rods are provided with threaded layers. . When the sterilizing device is in use, the sterilizing ultraviolet lamp is in a moving state to increase the range of sterilization. At the same time, in the process of moving, the surface of the sterilizing lamp can be scraped and cleaned to ensure that the sterilizing lamp is always in a high light transmission. sexual state.

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
