Description

Technical Field

[0001] The utility model relates to the field of sewage treatment equipment, in particular to a multi-stage sewage treatment device. Background Art

[0002] The patent document with the Chinese authorization announcement number CN220012373U discloses a multi-stage sewage treatment device. Although the multi-stage sewage treatment device can solve many technical problems, it also has technical problems: in the multi-stage sewage treatment device, an ultraviolet sterilization and disinfection tube is set in the sterilization and disinfection chamber, and the ultraviolet rays generated by the ultraviolet sterilization and disinfection tube are finally used to sterilize and disinfect the sewage. Although this can achieve a certain sterilization and disinfection effect, because the sewage is generally turbid, the ultraviolet rays generated by the ultraviolet sterilization and disinfection tube are easily blocked and absorbed by the turbid sewage, resulting in the difficulty of ultraviolet rays to fully and effectively act on the sewage, which is easy to cause the sterilization and disinfection effect of the sewage to be relatively limited, and then easily affects the treatment quality of the sewage. Although there are now sewage treatment devices with ozone sterilization, most of these sewage treatment devices now directly input ozone into a large treatment chamber through an air pipe, which is easy to cause ozone to not act on the sewage in an all-round way, resulting in a low treatment quality of the sewage. Therefore, it is very necessary to redesign the structure of the multi-stage sewage treatment device. Utility Model Content

[0003] The purpose of the utility model is to solve the above-mentioned problems and shortcomings and to provide a multi-stage sewage treatment device, which not only adds ozone sterilization, but also enables ozone to act on sewage very comprehensively and effectively, thereby achieving a very comprehensive and effective sterilization and disinfection effect on sewage, thereby greatly improving the treatment quality of sewage.

[0004] The technical solution of the utility model is achieved in this way:

[0005] A multi-stage sewage treatment device comprises a multi-stage sewage treatment device body, wherein a filter chamber and an ultraviolet sterilization and disinfection chamber are provided on the multi-stage sewage treatment device body, and an overflow channel for overflowing from the filter chamber to the ultraviolet sterilization and disinfection chamber is also provided on the multi-stage sewage treatment device body.

[0021] like Figures 1 to 3As shown, a multi-stage sewage treatment device described in the utility model comprises a multi-stage sewage treatment device body 1, on which a filter chamber 10 and an ultraviolet sterilization and disinfection chamber 20 are provided, and on which an overflow channel 30 for overflowing from the filter chamber 10 to the ultraviolet sterilization and disinfection chamber 20 is also provided. In order to achieve the purpose of the invention of the utility model, a strip-shaped overflow trough body 2 for overflowing ozone is invertedly arranged at the lower end of the overflow channel 30, and the length direction of the strip-shaped overflow trough body 2 is consistent with the length direction of the overflow channel 30 (the length direction is in the same direction as the length direction of the horizontal section of the overflow channel 30), and a brush stirring roller 3 is horizontally arranged at the upper end of the overflow channel 30, and the axial direction of the brush stirring roller 3 is consistent with the length direction of the overflow channel 30.

[0022] In the multi-stage sewage treatment device, a strip-shaped overflow trough 2 for overflowing ozone is arranged upside down in the lower end of the overflow channel 30, and the length direction of the strip-shaped overflow trough 2 is consistent with the length direction of the overflow channel 30; a brush stirring roller 3 is arranged horizontally in the upper end of the overflow channel 30, and the axial direction of the brush stirring roller 3 is consistent with the length direction of the overflow channel 30. This can make the strip-shaped overflow trough 2 overflow ozone distributed in a strip shape, and the strip-shaped ozone just corresponds to the length direction of the overflow channel 30, so that the distribution of ozone in the overflow channel 30 is very uniform; and because the overflow channel 30 is generally narrow, the ozone can act on the sewage in an all-round way. The brush stirring roller 3 arranged in the above-mentioned direction can play a very comprehensive and effective stirring role on the sewage passing through the overflow channel 30, which can play a comprehensive and effective stirring role on the sewage mixed with ozone through the brush stirring roller 3, which can not only achieve ozone sterilization, but also enable ozone to act on the sewage very comprehensively and effectively, thereby playing a very comprehensive and effective sterilization and disinfection role on the sewage, and thus can greatly improve the treatment quality of sewage.

[0023] During actual manufacturing, the inner cavity of the strip-shaped overflow trough body 2 is connected to the output port of the ozone generator (not shown in the figure), so that the ozone generator can be used to supply ozone to the strip-shaped overflow trough body 2, thus meeting the needs of actual use.

[0024] Since the overflow channel 30 is an overflow channel for overflowing from the filter chamber 10 to the ultraviolet sterilization and disinfection chamber 20, the sewage flowing into the overflow channel 30 is relatively stable and the turbulence in the sewage is relatively small, so that it is convenient for the strip overflow trough body 2 to stably overflow the strip-shaped distributed ozone, thereby being able to meet the actual use needs very well.

[0025] The brush of the brush stirring roller 3 is made of nylon brush, polypropylene brush, polyethylene brush or polyester resin brush, etc., and the roller shaft of the brush stirring roller 3 is made of stainless steel roller shaft, which not only enables the brush stirring roller 3 to have a good stirring effect, but also enables the brush stirring roller 3 to have high durability, thereby being able to meet the needs of actual use very well.

[0026] like Figure 1 , Figure 3 and Figure 7 As shown, there are two strip-shaped overflow trough bodies 2, which are respectively arranged on two channel walls in the width direction of the overflow channel 30, and a water gap 40 is reserved between the two strip-shaped overflow trough bodies 2.
