Description

Technical Field

[0001] The utility model provides a wastewater treatment device, belonging to the technical field of livestock and poultry breeding equipment, and particularly relates to a livestock and poultry breeding wastewater treatment device. Background Art

[0002] Livestock and poultry breeding wastewater treatment is to reduce environmental pollution and improve the reuse rate of water resources. The treatment process mainly includes three major steps: pretreatment, biological treatment, and advanced treatment. Pretreatment includes grid removal, regulating tank, and sedimentation tank, which are used to remove large particle solids and balance water quality. Biological treatment includes anaerobic digestion, aerobic treatment, and biological nitrogen and phosphorus removal, which are used to decompose organic matter and remove nutrients. Advanced treatment includes coagulation sedimentation, filtration, disinfection, and advanced oxidation, which are used to further purify water quality. The treated wastewater can meet the discharge standard or be used for purposes such as farmland irrigation. According to different factors, such as livestock and poultry species and breeding scale, different technical combinations and treatment processes can be adopted.

[0003] During the wastewater treatment process, incomplete treatment in the grid removal step may lead to affecting the biological treatment effect, increasing energy consumption and maintenance costs, and reducing the water quality purification effect. In long-term use, the screen needs to be treated in a timely manner to avoid blockage and affect the wastewater treatment effect. At the same time, the sizes of debris particles in the wastewater generated by different livestock and poultry are also different. Therefore, relative screen mesh sizes need to be adopted to achieve the best treatment effect. However, the screen replacement in existing grid removal equipment is not convenient enough and is inconvenient to use. Summary of the Utility Model

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs; the terms used in the description of the present invention in this specification are only for the purpose of describing specific implementation modes and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0025] As Figure 1 and Figure 2 shown, a livestock and poultry breeding wastewater treatment device includes a sedimentation tank 1, a grid structure 2 connected to the sedimentation tank 1 through a connecting pipe 11 on one side, and a biological treatment tank 18 connected to the sedimentation tank 1 through a connecting pipe 11 on the side far from the grid structure 2. A number of sedimentation tanks 1 and grid structures 2 are evenly distributed around the biological treatment tank 18. The grid structure 2 includes a screen 21 penetrating through the connecting pipe 11. A semi-circular sealing ring 22 corresponding to the connecting pipe 11 is fixedly connected to the screen 21. Seals 23 symmetrically distributed and corresponding to its own shape are connected to both sides of the sealing ring 22. A baffle 24 wider than itself is fixedly connected to the side of the sealing ring 22 away from the connecting pipe 1. A pressing ring 25 is connected to the other side of the baffle 24.

[0026] In this implementation plan, by setting the grid structure 2 connected to the sedimentation tank 1 through the connecting pipe 11, the screen 21 in the grid structure 2 realizes sealed connection with the connecting pipe 11 by means of the sealing ring 22. However, when the screen 21 needs to be replaced or cleaned, only the screen 21 needs to be taken out by means of the sealing ring 22. The structure is simple and easy to use; a number of groups of grid structures 2 and sedimentation tanks 1 are installed around the biological treatment tank 18, and various different wastewaters can be adapted by changing different screens 21.

[0027] AsFigure 3 and Figure 4 As shown in Figure 4 , a sealing groove 12 penetrating through one side plate body of the connecting ring 1 and corresponding to the sealing ring 22 is provided on the connecting ring 1. A clamping groove 13 corresponding to the seal strip 23 is provided on the side wall of the sealing groove 12. A support member 14 corresponding to itself is provided below the connecting ring 1. L-shaped fixing members 15 are provided on both sides of the support member 14. A fixing plate 16 fixedly connected to the pressing ring 25 is provided above the fixing member 15. The fixing plate 16 and the fixing member 15 are connected by a bolt structure 17 penetrating through itself. Limit rods 26 inserted into the support member 14 are fixedly connected to both ends of the blocking plate 24.

[0028] In this embodiment, the blocking plate 24 prevents the sealing ring 2 from sinking excessively; the pressing ring 25 is used to fix the screen 21 by means of the bolt structure 17. At the same time, the blocking plate 24 can be inserted into the interior of the support member 14 by means of the limit rods 26, which can strengthen the stability of the grille structure 2 after installation.

[0029] During use, the grille structure 2 is installed on one side of the sedimentation tank 1 and connected to the sedimentation tank 1 through the connecting pipe 11. A number of groups of grille structures 2 and sedimentation tanks 1 are also installed around the biological treatment tank 18 in the same way to meet different wastewater treatment requirements; when installing or replacing the screen 21, the screen 21 is hermetically connected to the connecting pipe 11 by means of the sealing ring 22. The screen 21 is fixed on the sealing ring 22. The sealing ring 22 conforms to the connecting pipe 11 through a semicircular design to ensure sealing performance and stability; the seal strips 23 on both sides of the sealing ring 22 are docked into the sealing groove 12 on the connecting pipe 11. A clamping groove 13 corresponding to the seal strip 23 is provided on the side wall of the sealing groove 12 to achieve a better sealing effect; the blocking plate 24 is installed on the side of the sealing ring 22 away from the connecting pipe 11, and through the cooperation of the pressing ring 25 and the bolt structure 17, the screen 21 is fixed in place so that it is not easily displaced. The blocking plate 24 is inserted into the support member 14 through the limit rods 26, which strengthens the installation stability of the entire grille structure 2. The L-shaped fixing member 15 and the fixing plate 16 further provide support and fixation to ensure the accurate position and stable operation of the screen and the sealing ring; when it is necessary to clean or replace the screen 21, the screen 21 can be simply removed for cleaning or replacement by loosening the pressing ring 25 and the bolt structure 17, and then reinstalled according to the above steps.

[0030] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Anyone familiar with this technology can make various modifications and decorations without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be defined by the claims.
