Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a uniform water distribution device for a multi-stage sulfur autotrophic denitrification filter. Background Technology

[0002] Multi-stage sulfur autotrophic denitrification filters are a highly efficient biological nitrogen removal system. They utilize sulfur autotrophic denitrifying bacteria to reduce nitrates in wastewater to nitrogen gas under anaerobic conditions, simultaneously generating sulfates. The sulfur autotrophic denitrification filter media primarily utilizes these bacteria for nitrogen removal. In an anaerobic environment, these bacteria use sulfur as an electron donor, requiring no organic carbon source, to reduce nitrates in wastewater to nitrogen gas.

[0003] In actual use, existing sulfur autotrophic denitrification filters require water distribution pipes when wastewater is introduced into the filter for treatment. Currently, these water distribution pipes are often located at the top opening of the filter or on the side wall of the filter. As water enters the filter, it is concentrated at the water distribution pipe, resulting in uneven water flow. This uneven water flow distribution leads to over-utilization of some areas of the filter media layer while under-utilization of others, which reduces the overall filtration efficiency. Summary of the Invention

[0004] In view of this, the present invention aims to propose a uniform water distribution device for a multi-stage sulfur autotrophic denitrification filter to solve the technical problem that the water flow cannot be evenly distributed, and the uneven water flow distribution will lead to over-utilization of some areas of the filter media layer while under-utilization of other areas, which will reduce the overall filtration efficiency.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0006] A uniform water distribution device for a multi-stage sulfur autotrophic denitrification filter includes a carrier plate disposed on the top of the filter, and further includes: a water distribution component that penetrates through the carrier plate and extends to the lower side of the carrier plate, the water distribution component being used for uniform water distribution; an agitation component that is installed at the bottom of the carrier plate, the agitation component being used for agitating the wastewater in the inlet tank; and four installation components that are evenly distributed in a ring on the four sides of the top of the carrier plate, each installation component including a connecting plate and an installation plate at the outer end of the connecting plate, the connecting plate being fixedly installed on the top of the carrier plate.

[0007] It should be understood that, firstly, the entire device is installed at the top opening of the filter tank using the installation components. Then, the water distribution components are used to evenly distribute water into the filter tank. Even water distribution ensures that the water flow is more uniformly distributed on the filter media, which is beneficial for making full use of the filter media's filtration area. Furthermore, during the water distribution process, the agitator components can be used to stir the wastewater introduced into the tank, which further improves the uniformity of the water in the tank. At the same time, it can also improve the contact effect between the wastewater and the bacteria in the tank, which is beneficial for improving the wastewater treatment effect.

[0008] Furthermore, the water distribution assembly includes: a hollow shaft that passes through the carrier plate and has water distribution pipes fixedly connected to both sides of its tail end, with a short pipe fixedly connected to the bottom of the water distribution pipes; a servo motor that is fixed to the top of the carrier plate, with a second gear fixedly connected to the outer end of the drive shaft of the servo motor, and a first gear fixedly fitted onto the outer wall of the hollow shaft, the first gear and the second gear meshing, and the servo motor used to drive the hollow shaft to rotate.

[0009] It should be noted that water is introduced into the pool through water distribution pipes and short pipes, and the servo motor drives the second gear to rotate, which in turn drives the first gear to rotate, thereby enabling the hollow shaft and water distribution pipes to rotate, thus achieving uniform water distribution.

[0010] Furthermore, the agitation assembly includes: two rotating shafts distributed on the lower side of the water distribution pipes on both sides, one end of each rotating shaft passing through the water distribution pipe and fixedly connected to a third gear; an external gear ring fixed to the bottom of the carrier plate, the external gear ring meshing with the third gear; and multiple stirring blades evenly fixed on the lower side of the outer wall of the rotating shaft, the stirring blades being inclined.

[0011] It should be understood that during the rotation of the water distribution assembly, the rotating shaft rotates along with the water distribution pipe. During this rotation, the outer gear ring remains stationary, while the third gear rotates along the outer wall of the outer gear ring. This causes the rotating shaft to rotate, which in turn causes the stirring blades to rotate, agitating the wastewater. This further improves the uniformity of the water in the tank and enhances the contact between the wastewater and the bacteria within the tank, thus improving the wastewater treatment effect. Furthermore, the inclined design of the stirring blades not only causes the wastewater to rotate horizontally but also to move vertically. The two stirring blades agitate the water in opposite directions at the confluence, causing the wastewater to collide, further enhancing the agitation effect and thus improving the bacteria's treatment effect on the wastewater.

[0012] Compared to existing technologies, the water distribution device for a multi-stage sulfur autotrophic denitrification filter described in this utility model can rotate under the action of gear drive through the water distribution pipe in the water distribution component, thereby achieving uniform water distribution in the filter. Uniform water distribution can ensure that the water flow is more evenly distributed on the filter media, which is conducive to making full use of the filtration area of ​​the filter media and improving the overall filtration effect.

[0013] The water distribution device for a multi-stage sulfur autotrophic denitrification filter described in this utility model allows the rotating shaft to rotate during the rotation of the water distribution pipe. This interaction between the third gear and the external gear ring drives the third gear to rotate, which in turn drives the rotating shaft to rotate, thereby causing the stirring blades to rotate. This agitates the wastewater, further improving the uniformity of the water in the tank and enhancing the contact between the wastewater and the bacteria in the tank, thus improving the wastewater treatment effect.

[0014] Furthermore, the agitator blades are tilted, which not only causes the wastewater to rotate horizontally, but also causes it to move up and down. The agitators on both sides stir the water in opposite directions at the confluence, causing the wastewater to collide, which further enhances the stirring effect and thus improves the treatment effect of the bacteria on the wastewater.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-5As shown in the figure, as an embodiment, a water distribution device for a multi-stage sulfur autotrophic denitrification filter includes a carrier plate 1, which is disposed on the top of the filter. It also includes: a water distribution component, which penetrates through the carrier plate 1 and extends to the lower side of the carrier plate 1, and is used to distribute water evenly; an agitation component, which is installed at the bottom of the carrier plate 1 and is used to agitate the sewage in the inlet tank; and four installation components, which are evenly distributed in a ring on the top four sides of the carrier plate 1. The installation components include a connecting plate 11 and an installation plate 12 at the outer end of the connecting plate 11, and the connecting plate 11 is fixedly installed on the top of the carrier plate 1.

[0028] It should be understood that, firstly, the entire device is installed at the top opening of the filter tank using the installation components. Then, the water distribution components are used to evenly distribute water into the filter tank. Even water distribution ensures that the water flow is more uniformly distributed on the filter media, which is beneficial for making full use of the filter media's filtration area. Furthermore, during the water distribution process, the agitator components can be used to stir the wastewater introduced into the tank, which further improves the uniformity of the water in the tank. At the same time, it can also improve the contact effect between the wastewater and the bacteria in the tank, which is beneficial for improving the wastewater treatment effect.

[0029] like Figure 1 , Figure 2 , Figure 4 As shown in the figure, as an embodiment, the water distribution assembly includes: a hollow shaft 2, which passes through the carrier plate 1 and has water distribution pipes 21 fixedly connected to both sides of its tail end; a plurality of evenly distributed short pipes 22 fixedly connected to the bottom of the water distribution pipes 21; a servo motor 25, which is fixed to the top of the carrier plate 1; a second gear 24 fixedly connected to the outer end of the drive shaft of the servo motor 25; a first gear 23 fixedly fitted on the outer wall of the hollow shaft 2; the first gear 23 meshing with the second gear 24; and the servo motor 25 used to drive the hollow shaft 2 to rotate; and a sewage pipe 13, which is connected to the hollow shaft 2 through a rotary joint 14; and the sewage pipe 13 used to guide sewage into the hollow shaft 2.

[0030] It should be understood that the sewage to be treated is introduced into the hollow shaft 2 through the sewage pipe 13, and then the water is discharged and distributed by the water distribution pipe 21 and the short pipe 22. The servo motor 25 drives the second gear 24 to rotate, thereby driving the first gear 23 to rotate, which in turn drives the hollow shaft 2 and the water distribution pipe 21 to rotate, thereby achieving uniform water distribution.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown in the figure, as an embodiment, the stirring assembly includes: a rotating shaft 3, there are two rotating shafts 3, distributed on the lower side of the water distribution pipes 21 on both sides, one end of the rotating shaft 3 passes through the water distribution pipe 21 and is fixedly connected to a third gear 32; an external gear ring 33, the external gear ring 33 is fixed to the bottom of the carrier plate 1, the external gear ring 33 and the third gear 32 mesh; and a stirring blade 31, there are multiple stirring blades 31, the multiple stirring blades 31 are evenly fixed on the lower side of the outer wall of the rotating shaft 3, and the stirring blades 31 are inclined.

[0032] It should be understood that during the rotation of the water distribution assembly, the rotating shaft will rotate along with the water distribution pipe 21. During the rotation, the outer gear ring 33 remains stationary, while the third gear 32 rotates along the outer wall of the outer gear ring 33. This causes the rotating shaft 3 to rotate, which in turn causes the stirring blades 31 to rotate, thus agitating the sewage. This helps to further improve the uniformity of the water in the tank and also enhances the contact effect between the sewage and the bacteria in the tank, thereby improving the sewage treatment effect. Furthermore, the stirring blades 31 are tilted, so they can not only move the sewage horizontally but also cause it to move up and down. The stirring blades 31 on both sides agitate the water in opposite directions at the confluence, causing the sewage to collide, which further enhances the agitation effect and further improves the sewage treatment effect of the bacteria.

[0033] like Figure 1 As shown in the figure, as an embodiment, mounting holes are provided on both sides of the top of the mounting plate 12. The mounting holes facilitate the installation and fixing of the mounting plate 12.
