Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device using the SBR process. Background Technology
[0002] The SBR process, also known as the intermittent aerated activated sludge process or sequencing batch activated sludge process, is characterized by treating wastewater in batches in an intermittent operation mode. Each reactor functions as both an aeration tank and a secondary sedimentation tank, thus eliminating the need for a secondary sedimentation tank and a sludge return section.
[0003] Existing SBR wastewater treatment devices suffer from uneven aeration distribution during aeration, failing to aerate different depths of the wastewater. Furthermore, after treatment, sludge adheres to the inner wall of the treatment tank, requiring tedious and laborious scraping to remove it. This method fails to reduce the area requiring sludge removal by scraping the inner wall.
[0004] Therefore, an SBR process wastewater treatment device is proposed. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as uneven and singular aeration distribution, and failure to aerate different depths of wastewater. Therefore, this invention proposes an SBR process wastewater treatment device.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] Design an SBR process wastewater treatment device, including a treatment tank, with a partition plate fixed inside the treatment tank, a support column fixed in the middle of the partition plate, a lifting mechanism at the top of the support column, and a positioning mechanism installed at the top of the side of the support column. An aeration mechanism is uniformly installed inside the treatment tank. The lifting mechanism includes a lifting column and a lifting frame. The support column has an insertion groove inside, and the bottom end of the lifting column slides into the insertion groove, with gears meshing on its side. The lifting frame is fixed to the top of the lifting column, and an installation mechanism is provided at the bottom of the outer end of the lifting frame. The positioning mechanism includes a positioning column that passes through the side of the support column and inserts into the side of the lifting column. The aeration mechanism includes an aerator, with an aeration duct connected to the bottom of the aerator.
[0008] Furthermore, one side of the lifting column is evenly provided with toothed grooves, and a mounting plate is fixed to one side of the top of the support column. The gear is rotatably installed between the two mounting plates and meshes with the toothed grooves for transmission. A motor is installed at one end of the gear, and the motor is fixedly installed on the side of the mounting plate.
[0009] Furthermore, the gear is horizontally arranged, and both the support column and the lifting column are cylindrical structures and are vertically arranged.
[0010] Furthermore, a first positioning hole is opened at the top side of the insertion slot, and a second positioning hole is opened on the other side of the lifting column. The positioning column slides through the first positioning hole and is inserted into the second positioning hole. A push-pull plate is fixed to the outer end of the positioning column, and an electric push rod is installed on the inner side of the bottom end of the push-pull plate.
[0011] Furthermore, the first positioning hole and the second positioning hole are horizontally aligned, the positioning post is horizontally positioned, the push-pull plate is vertically positioned on the outside of the support post, and the electric push rod is horizontally fixedly installed on the outside of the support post.
[0012] Furthermore, the installation mechanism includes a mounting frame and connecting rods. The mounting frame is fixed to the outer end of the lifting frame, and the connecting rods are evenly fixed to the bottom of the outer end of the mounting frame. The bottom ends of the four connecting rods are fixed with connecting frames, which are located at the bottom of the inner interior of the treatment pool.
[0013] Furthermore, both the lifting frame and the mounting frame are cross-shaped structures and are horizontally arranged, the connecting rod is vertically arranged, and the connecting frame is a rectangular structure, with its outer side scraping against the inner wall of the treatment pool and the inner wall of the partition plate.
[0014] Furthermore, the aerator is installed at the bottom center of the mounting frame, the aeration duct is vertically arranged, and aeration pipes are fixedly distributed on its side in a vertical manner. The aeration pipes have a cross-shaped structure and are horizontally arranged. Their outer ends are fixedly connected to the connecting rod. Aeration holes are evenly connected to the bottom of the aeration pipes. All aeration holes are arranged downwards. The lowest aeration hole is spaced apart from the bottom of the treatment tank. A drain pipe is connected to the top side of the treatment tank. The partition plate has a cross-shaped structure and is vertically arranged.
[0015] The SBR process wastewater treatment device proposed in this utility model has the following advantages:
[0016] 1. This utility model uses a support column fixed in the middle of a partition plate inside the treatment tank. A lifting column is inserted into the middle of the support column and connected by gears and tooth grooves. Therefore, during the aeration treatment of sewage in the treatment tank by the aerator, aeration duct, and aeration pipe, the motor drives the gear to rotate in both directions, thereby driving the lifting column to move up and down at the top of the support column through the tooth grooves. In turn, the lifting frame, mounting frame, and aeration duct drive the aeration pipe to move up and down reciprocally. In this way, the vertically distributed cross-shaped aeration pipes can aerate sewage at different depths in the treatment tank, improving the sewage aeration range and sewage treatment effect.
[0017] 2. In this invention, during the reciprocating motion of the lifting column and the mounting frame, the connecting rod drives the connecting frame to move up and down inside the treatment tank, scraping and contacting the partition plate and the inner wall of the treatment tank to remove adhering sludge. Furthermore, after sewage aeration, during the sedimentation process, the lifting column lowers the lifting frame, and the connecting frame abuts against the bottom of the treatment tank. An electric push rod drives the positioning column to stably connect the lifting column and the support column, maintaining the stability of the connecting rod and the connecting frame, thus protecting the sewage inside the treatment tank from static sedimentation. Moreover, when cleaning sludge inside the treatment tank, the lifting column can drive the lifting frame, mounting frame, connecting rod, and connecting frame to rise and fall, allowing the connecting frame to scrape and clean the sludge from the inner wall of the treatment tank and the partition plate, reducing the area requiring scraping and cleaning inside the treatment tank and increasing the sludge cleaning speed.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] For examples, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shows an SBR process wastewater treatment device, including a treatment tank 1. A partition plate 3 is fixed inside the treatment tank 1. A support column 12 is fixed in the middle of the partition plate 3. A lifting mechanism is provided at the top of the support column 12. A positioning mechanism is installed at the top of the side of the support column 12. An aeration mechanism is uniformly installed inside the treatment tank 1.
[0026] The lifting mechanism includes a lifting column 19 and a lifting frame 9. The support column 12 has an insertion groove 15 inside. The bottom end of the lifting column 19 is slidably inserted into the insertion groove 15, and a gear 14 is meshed on its side. The lifting frame 9 is fixed to the top of the lifting column 19, and an installation mechanism is provided at the bottom of the outer end of the lifting frame 9.
[0027] The lifting column 19 has evenly spaced toothed grooves 20 on one side. The top of the support column 12 is fixed with a mounting plate 21. The gear 14 is rotatably installed between the two mounting plates 21 and meshes with the toothed grooves 20 for transmission. A motor 13 is installed at one end of the gear 14 and is fixedly installed on the side of the mounting plate 21.
[0028] The gear 14 is horizontally positioned, while the support column 12 and the lifting column 19 are both cylindrical structures and are vertically positioned.
[0029] The installation mechanism includes a mounting frame 8 and connecting rods 6. The mounting frame 8 is fixed to the outer end of the lifting frame 9. The connecting rods 6 are evenly fixed to the bottom of the outer end of the mounting frame 8. The bottom of the four connecting rods 6 is fixed with a connecting frame 18, which is located at the bottom of the inside of the treatment pool 1.
[0030] Both the lifting frame 9 and the mounting frame 8 are cross-shaped structures and are horizontally arranged. The connecting rod 6 is vertically arranged. The connecting frame 18 is a rectangular structure, and its outer side scrapes against the inner wall of the treatment pool 1 and the inner wall of the partition plate 3.
[0031] During the process of the lifting column 19 driving the mounting frame 8 to move up and down, the connecting rod 6 drives the connecting frame 18 to move up and down inside the treatment pool 1, and scrapes and contacts the partition plate 3 and the inner wall of the treatment pool 1 to clean away the adhering sludge.
[0032] When cleaning the sludge inside the treatment tank 1, the lifting column 19 can drive the lifting frame 9, the mounting frame 8, the connecting rod 6 and the connecting frame 18 to rise and fall, so that the connecting frame 18 can scrape and clean the sludge on the inner wall of the treatment tank 1 and the partition plate 3, thereby reducing the area inside the treatment tank 1 that needs to be scraped and cleaned and improving the sludge cleaning speed.
[0033] The aeration mechanism includes an aerator 7, and the bottom end of the aerator 7 is connected to an aeration duct 4.
[0034] The aerator 7 is installed at the bottom center of the mounting frame 8. The aeration duct 4 is vertically arranged, and aeration pipes 5 are fixedly arranged vertically on its side. The aeration pipes 5 have a cross-shaped structure and are horizontally arranged. Their outer ends are fixedly connected to the connecting rod 6. Aeration holes 17 are evenly connected to the bottom of the aeration pipes 5. All aeration holes 17 are arranged downwards. The lowest aeration hole 17 is spaced apart from the bottom of the treatment tank 1. The top side of the treatment tank 1 is connected to the drain pipe 2. The partition plate 3 has a cross-shaped structure and is vertically arranged.
[0035] During the aeration treatment of sewage in treatment tank 1 via aerator 7, aeration duct 4, and aeration pipe 5, motor 13 drives gear 14 to rotate in both directions, thereby driving lifting column 19 to move up and down at the top of support column 12 via tooth groove 20. In turn, lifting frame 9, mounting frame 8, and aeration duct 4 drive aeration pipe 5 to move up and down reciprocally. In this way, the vertically distributed cross-shaped aeration pipe 5 can aerate sewage at different depths in treatment tank 1, improving the sewage aeration range and sewage treatment effect.
[0036] The positioning mechanism includes a positioning post 10, which passes through the side of the support post 12 and is inserted into the side of the lifting post 19.
[0037] The top side of the insertion slot 15 has a first positioning hole 16, and the other side of the lifting column 19 has a second positioning hole 22. The positioning column 10 slides through the first positioning hole 16 and is inserted into the second positioning hole 22. The outer end of the positioning column 10 is fixed with a push-pull plate 23, and an electric push rod 11 is installed on the inner side of the bottom end of the push-pull plate 23.
[0038] The first positioning hole 16 and the second positioning hole 22 are horizontally aligned, the positioning post 10 is horizontally set, the push-pull plate 23 is vertically set on the outside of the support post 12, and the electric push rod 11 is horizontally fixedly installed on the outside of the support post 12.
[0039] After the sewage is aerated, during the sedimentation process, the lifting column 19 lowers the lifting frame 9, and the connecting frame 18 abuts against the bottom of the treatment tank 1. The electric push rod 11 drives the positioning column 10 to position and stably connect the lifting column 19 and the support column 12, keeping the connecting rod 6 and the connecting frame 18 stable, and keeping the sewage inside the treatment tank 1 statically sedimented.
[0040] Working method: A support column 12 is fixed in the middle of the partition plate 3 inside the treatment tank 1. The lifting column 19 is inserted into the middle of the support column 12 and is connected to the tooth groove 20 through the gear 14. Therefore, during the process of aerating the sewage in the treatment tank 1 through the aerator 7, aeration duct 4 and aeration pipe 5, the motor 13 drives the gear 14 to rotate in both directions. This drives the lifting column 19 to move up and down at the top of the support column 12 through the tooth groove 20. Then, the lifting frame 9, mounting frame 8 and aeration duct 4 drive the aeration pipe 5 to move up and down. In this way, the vertically distributed cross-shaped aeration pipe 5 can aerate sewage at different depths in the treatment tank 1, improving the sewage aeration range and sewage treatment effect.
[0041] During the reciprocating motion of the lifting column 19 and the mounting frame 8, the connecting rod 6 drives the connecting frame 18 to move up and down inside the treatment tank 1, scraping and contacting the partition plate 3 and the inner wall of the treatment tank 1 to remove the adhering sludge. Moreover, after the sewage aeration is completed and during the sedimentation process, the lifting column 19 drives the lifting frame 9 to lower, and the connecting frame 18 abuts against the bottom of the treatment tank 1. The electric push rod 11 drives the positioning column 10 to position and stably connect the lifting column 19 and the support column 12, keeping the connecting rod 6 and the connecting frame 18 stable and keeping the sewage inside the treatment tank 1 stationary and settling. Furthermore, when cleaning the sludge inside the treatment tank 1, the lifting column 19 can drive the lifting frame 9, the mounting frame 8, the connecting rod 6 and the connecting frame 18 to rise and fall, so that the connecting frame 18 can scrape and clean the sludge inside the treatment tank 1 and the inner wall of the partition plate 3, reducing the area inside the treatment tank 1 that needs to be scraped and cleaned, and improving the sludge cleaning speed.
[0042] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
