Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, and in particular to a high-efficiency denitrification modified AAO process wastewater treatment system. Background Technology

[0002] The AAO process, also known as the A2O process, is an abbreviation of the first letters of the English word Anaerobic-Anoxic-Oxic. It is a commonly used wastewater treatment process. This process was developed in the 1970s by some experts in the United States based on the anaerobic-aerobic (An-O) denitrification process, combined with traditional activated sludge processes, biological nitrification and denitrification processes, and biological phosphorus removal processes. It is a wastewater treatment process that can simultaneously remove nitrogen and phosphorus.

[0003] Existing wastewater treatment systems typically use filters to remove impurities from wastewater. However, these filters are usually installed in a parallel configuration. While this allows for a larger filtration area, it also makes the filters prone to clogging after impurities accumulate, thus affecting the efficiency of separating wastewater from impurities. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a high-efficiency denitrification modified AAO process wastewater treatment system, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a high-efficiency denitrification modified AAO process wastewater treatment system, including a treatment tank and a motor. The top of the treatment tank is provided with a cover plate, and a drain chamber is fixedly installed on the top of the cover plate. Two overlapping strips 1 are fixedly provided on the inner wall of the treatment tank, and a filter plate 1 is attached to the top of the two overlapping strips 1. Two overlapping strips 2 are fixedly installed on the inner wall of the treatment tank, and a filter plate 2 is attached to the top of the two overlapping strips 2. A gear 1 is fixedly connected to the power output shaft of the motor. A helical blade 1 is fixedly connected to the side of the gear 1 away from the motor. A gear 2 meshes with the outer edge of the gear 1. A helical blade 2 is fixedly connected to the side of the gear 2 near the helical blade 1. A feeding pipe is fixedly connected to the outer wall of the treatment tank.

[0006] In a preferred embodiment, the top of the processing box has two symmetrical slots, and the bottom of the cover plate has two electromagnetic plates fixedly mounted symmetrically. The two electromagnetic plates are inserted into the inner walls of the two slots, and the processing box is made of magnetic material.

[0007] By adopting the above technical solution, the electromagnetic plate can be stably adsorbed onto the inner wall of the two slots using the magnetic attraction principle, thereby achieving stable positioning of the cover plate on the top of the processing box. After the magnetism of the electromagnetic plate is eliminated, the cover plate can be quickly removed from the top of the processing box, thus achieving disassembly.

[0008] In a preferred embodiment, a sealing cover is rotatably connected to the top of the water tank, and an observation window is fixedly fitted to the inner wall of the cover plate. The observation window is made of transparent tempered glass.

[0009] By adopting the above technical solution, the top of the drain tank can be sealed with a sealing cover, ensuring that foreign objects from the outside will not enter the interior when not in use. Furthermore, the state of wastewater treatment inside the treatment chamber and the state of solid foreign matter and impurities accumulated on the top of the filter plate can be clearly observed when the cover is not opened, thus facilitating timely cleaning.

[0010] In a preferred embodiment, a water outlet pipe is fixedly connected to the bottom of the treatment tank, and a valve is fixedly installed on the inner wall of the water outlet pipe.

[0011] By adopting the above technical solution, the filtered and purified sewage can be discharged into the water storage device through the outlet pipe, and the inner cavity of the outlet pipe can be sealed by a valve to ensure that the sewage will not drip out of the outlet pipe at will.

[0012] In a preferred embodiment, a valve two is fixedly installed on the inner wall of the feeding pipe, and the end of the feeding pipe near the processing box is located below the filter plate two.

[0013] By adopting the above technical solution, the inner cavity of the feeding pipe can be sealed by valve two, ensuring that foreign objects and impurities will not enter the inner cavity of the treatment tank through the feeding pipe. Valve two can be opened to add flocculants and disinfectants used for purifying sewage into the inner cavity of the treatment tank through the feeding pipe.

[0014] In a preferred embodiment, a bracket is fixedly mounted on the outer side of the processing box, the motor is fixedly mounted on the inner wall of the bracket, there are two gears and two helical blades, and the two gears and two helical blades are symmetrically arranged on both sides of the gear one. The gear one meshes with the two gears two. Three rings are fixedly mounted on the inner wall of the processing box, and the ends of the helical blade one and the two helical blades away from the gear one and the two gears two are rotatably connected to the inner wall of the rings.

[0015] By adopting the above technical solution, the motor can be fixed by the bracket, ensuring its stability during operation. When gear one rotates, it drives the two gears two and the two spiral blades two to rotate synchronously, thereby achieving the stirring and mixing of sewage, flocculant and disinfectant at the bottom of the treatment tank. In addition, the spiral blades one and the two spiral blades two can drive the sewage, flocculant and disinfectant at the bottom of the treatment tank to move back and forth for mixing, ensuring uniform mixing.

[0016] In a preferred embodiment, a controller is fixedly mounted on the outside of the processing box, and the controller is electrically connected to the motor.

[0017] By adopting the above technical solution, the controller can operate the motor, thereby improving the intelligence of the device.

[0018] In a preferred embodiment, both filter plates 1 and 2 are inclinedly arranged on the inner wall of the processing box, the density of filter plate 2 is less than that of filter plate 1, and handles are fixedly mounted on the top of filter plates 1 and 2.

[0019] By adopting the above technical solution, wastewater can be filtered in two ways using filter plate one and filter plate two. The filtered impurities can accumulate on one side of the top of filter plate one and filter plate two, thus preventing complete blockage of filter plate one and filter plate two. This allows for continuous filtration of subsequent wastewater, ensuring filtration efficiency.

[0020] The beneficial effects of this application are:

[0021] 1. This high-efficiency denitrification modified AAO process wastewater treatment system uses filter plate one and filter plate two for dual filtration of impurities. The filtered impurities can accumulate on one side of the lower top of filter plate one and filter plate two, thus preventing complete blockage of filter plate one and filter plate two. It can continuously filter subsequent wastewater, ensuring filtration efficiency and not affecting the efficiency of separating wastewater from impurities during wastewater treatment.

[0022] 2. This high-efficiency denitrification modified AAO process wastewater treatment system adds flocculants and disinfectants used for wastewater purification into the inner cavity of the treatment tank through a feeding pipe. A motor drives gear one to rotate, which in turn drives two gears two and two spiral blades two to rotate synchronously. This achieves stirring and mixing of the wastewater, flocculants, and disinfectants at the bottom of the treatment tank. Furthermore, the spiral blades one and two spiral blades two can drive the wastewater, flocculants, and disinfectants at the bottom of the treatment tank to move back and forth for mixing, ensuring uniform mixing and disinfection purification.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Reference Figure 1-4 A high-efficiency denitrification modified AAO process wastewater treatment system includes a treatment tank 1 and a motor 11. The top of the treatment tank 1 is provided with a cover plate 2, and a drain chamber 5 is fixedly installed on the top of the cover plate 2. Two overlapping strips 7 are fixedly installed on the inner wall of the treatment tank 1, and a filter plate 8 is attached to the top of the two overlapping strips 7. Two overlapping strips 9 are fixedly installed on the inner wall of the treatment tank 1, and a filter plate 10 is attached to the top of the two overlapping strips 9. A gear 12 is fixedly connected to the power output shaft of the motor 11. A spiral blade 13 is fixedly connected to the side of the gear 12 away from the motor 11. A gear 14 meshes with the outer edge of the gear 12. A spiral blade 15 is fixedly connected to the side of the gear 14 near the spiral blade 13. A feeding pipe 19 is fixedly connected to the outer wall of the treatment tank 1.

[0030] See Figure 2 The top of the processing box 1 has two symmetrical slots 3, and the bottom of the cover plate 2 is symmetrically fixed with two electromagnetic plates 4. The two electromagnetic plates 4 are inserted into the inner wall of the two slots 3. The processing box 1 is made of magnetic material, so the electromagnetic plates 4 can be stably attracted to the inner wall of the two slots 3 by using the magnetic attraction principle. Thus, the cover plate 2 can be stably positioned on the top of the processing box 1. After the magnetism of the electromagnetic plates 4 is eliminated, the cover plate 2 can be quickly removed from the top of the processing box 1, thus achieving disassembly.

[0031] See Figure 1 and Figure 2 The top of the drain tank 5 is rotatably connected to a sealing cover. The inner wall of the cover plate 2 is fixedly fitted with an observation window 6, which is made of transparent tempered glass. This allows the top of the drain tank 5 to be sealed with the sealing cover, ensuring that foreign objects from the outside will not enter the interior when not in use. Furthermore, when the cover plate 2 is not opened, the state of sewage treatment in the inner cavity of the treatment tank 1 and the state of solid foreign matter and impurities accumulated on the top of the filter plate 8 can be clearly observed, which facilitates timely cleaning.

[0032] See Figure 1 The bottom of the treatment tank 1 is fixedly connected to a water outlet pipe 16, and a valve 17 is fixedly installed on the inner wall of the water outlet pipe 16, so that the filtered and purified sewage can be discharged into the water storage mechanism through the water outlet pipe 16, and the inner cavity of the water outlet pipe 16 can be sealed by the valve 17 to ensure that the sewage will not drip to the outside through the water outlet pipe 16 at will.

[0033] See Figure 2 A valve 20 is fixedly installed on the inner wall of the feeding pipe 19. The end of the feeding pipe 19 near the treatment box 1 is located below the filter plate 2 10, so that the inner cavity of the feeding pipe 19 can be sealed by the valve 20 to ensure that foreign objects and impurities do not enter the inner cavity of the treatment box 1 through the feeding pipe 19. The valve 20 can be opened to add flocculant and disinfectant used for purifying sewage into the inner cavity of the treatment box 1 through the feeding pipe 19.

[0034] See Figure 3 and Figure 4 A bracket 21 is fixedly mounted on the outside of the treatment tank 1. The motor 11 is fixedly installed on the inner wall of the bracket 21. There are two gears 14 and two spiral blades 15, which are symmetrically arranged on both sides of gear 12. Gear 12 meshes with the two gears 14. Three rings are fixedly mounted on the inner wall of the treatment tank 1. The ends of spiral blade 13 and two spiral blades 15 away from gear 12 and two gears 14 are rotatably connected to the inner wall of the rings. This allows the bracket 21 to fix the motor 11, ensuring its stability during operation. When gear 12 rotates, it drives spiral blade 13 to rotate, which in turn drives two gears 14 and two spiral blades 15 to rotate synchronously. This achieves the stirring and mixing of sewage, flocculant, and disinfectant at the bottom of the treatment tank 1. Spiral blade 13 and two spiral blades 15 can drive the sewage, flocculant, and disinfectant at the bottom of the treatment tank 1 to move back and forth for mixing, ensuring uniform mixing.

[0035] See Figure 1 and Figure 4 A controller 18 is fixedly mounted on the outside of the processing box 1. The controller 18 is electrically connected to the motor 11, so that the controller 18 can control the operation of the motor 11, thereby improving the intelligence of the device.

[0036] See Figure 3 and Figure 4Both filter plates 8 and 10 are inclinedly arranged on the inner wall of the treatment tank 1. The density of filter plate 10 is less than that of filter plate 8. The top of filter plates 8 and 10 is fixedly equipped with handles, which allows for double filtration of sewage using filter plates 8 and 10. The filtered impurities can accumulate on one side of the top of filter plates 8 and 10, thus preventing complete blockage of filter plates 8 and 10. This allows for continuous filtration of subsequent sewage, ensuring filtration efficiency.

[0037] Working Principle: When using this device, the wastewater to be treated is first discharged into the inner cavity of the treatment tank 1 through the drain 5. Impurities are then subjected to double filtration through filter plate 8 and filter plate 10. The filtered impurities accumulate on the lower side of the top of filter plate 8 and filter plate 10, preventing complete blockage and ensuring continuous filtration of subsequent wastewater. Then, valve 20 is opened, and the flocculant and disinfectant used for wastewater purification are added into the inner cavity of the treatment tank 1 through the feed pipe 19. The motor 11 drives gear 12 to rotate, which in turn drives the spiral blades 13 to rotate, simultaneously rotating two gears 14 and two spiral blades 15. This achieves the simultaneous filtration of wastewater, flocculant, and disinfectant at the bottom of the treatment tank 1. The stirring and mixing of the wastewater, flocculant, and disinfectant at the bottom of the treatment tank 1, along with the spiral blades 13 and 15, ensures uniform mixing and disinfection. The filtered and purified wastewater is discharged into the water storage mechanism through the outlet pipe 16. The valve 17 can be used to seal the inner cavity of the outlet pipe 16 to prevent wastewater from dripping out of the outside. After the magnetism of the electromagnetic plate 4 is eliminated, the cover plate 2 can be quickly removed from the top of the treatment tank 1 for disassembly. First, the foreign objects accumulated at the lowest point of the top of the filter plate 8 can be removed. Then, the handle can be pulled to remove the filter plate 8 to the outside for cleaning and maintenance. Then, the foreign objects accumulated at the lowest point of the top of the filter plate 10 can be removed. Then, the handle can be pulled to remove the filter plate 10 to the outside for cleaning and maintenance.
