Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a dual-aeration wastewater treatment device that improves the denitrification effect of RPIR. Background Technology

[0002] In the process of sewage treatment, it is necessary to aerate the sewage. Aeration involves adding air to the sewage to prevent suspended matter from settling in the aeration tank and to provide more oxygen for aerobic microorganisms in the water. This enhances the contact between organic matter, microorganisms, and dissolved oxygen in the aeration tank, thereby oxidizing and decomposing the organic matter in the sewage.

[0003] According to a patent document with publication number CN218775288U, a dual-aeration wastewater treatment device includes an aeration tank, several aeration discs, and an aeration mechanism. The aeration tank stores wastewater to be treated. The aeration discs are installed on the bottom wall of the aeration tank, with the air outlet of each disc pointing vertically upwards. The air inlets of the aeration discs are connected to air pipes, and air supply devices are installed at the inlets of the air pipes to introduce high-pressure air. The aeration mechanism extends into the wastewater. This technical solution... During operation, the air outlet of the floating aeration port creates a water flow in the wastewater. This causes the sludge blown upwards by the aeration discs and sludge aeration pipes to be subjected to a lateral force, resulting in the floating sludge moving randomly with the water flow. The sludge, blown upwards, is less susceptible to gravity and does not immediately sink, thus forming sludge deposits again. This increases the contact area and time between the organic matter in the sludge and the water, facilitating the decomposition of organic matter. However, while this technical solution achieves the decomposition of organic matter, it cannot quickly move the gas to different locations in the wastewater, causing inconvenience during use. Therefore, there is an urgent need to design a solution to address these issues. Utility Model Content

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-6As shown in the figure, this utility model provides a dual-aeration wastewater treatment device for improving RPIR denitrification effect, including a base 1, a tank body 2 fixed on the base 1, a groove 4 on the top of the tank body 2, and a support mechanism 5 fixedly installed inside the groove 4. The support mechanism 5 is a support spring, which drives a motor base 6 to move via a slider. Later, after the motor base 6 loses its limit position, the support mechanism 5 drives the motor base 6 to move quickly to one end of the tank body 2. A slider is fixed to one end of the support mechanism 5, and a motor base 6 is fixed to one end of the slider. A drive motor 7 is fixedly installed on the motor base 6, and an agitator is installed on the drive motor 7. The mixing assembly has a support tube 8 welded onto the base 1. A limiting post 9 is movably installed inside the support tube 8. The limiting post 9 is installed inside the support tube 8 by a spring spring. Under the push of the spring spring, the limiting post 9 enters into the limiting hole. The limiting post 9 provides a limiting fixation for the limiting plate 10, so that the motor base 6 is located at the top of the tank 2 for mixing. The limiting plate 10 is movably installed on the limiting post 9. One end of the limiting plate 10 is welded to the motor base 6. The limiting plate 10 has a limiting hole. The drive motor 7 drives the mixing assembly to make the sewage flow. While the sewage flows, it is easy to quickly introduce oxygen into the sewage at different locations.

[0025] In this embodiment, a drain pipe 3 is fixedly installed at one end of the pool body 2, and an inlet pipe 11 is fixedly installed at the other end of the pool body 2. A motor box 12 is fixedly installed on one side of the base 1 and the pool body 2. An air pump is fixedly installed inside the motor box 12. After the air pump pressurizes the gas, it enters the aeration disc 18 through the air inlet pipe 13. At the same time, the gas is discharged from the air outlet 19, and the fixed plate 16 moves the gas to change the position of the rising gas, so that the aeration point is changed for aeration. An air inlet pipe 13 is fixedly installed on the air pump, and one end of the air inlet pipe 13 is fixedly installed inside the pool body 2. The stirring assembly includes a rotating pipe 14. One end of the rotating pipe 14 is fixed to the drive motor 7. A movable pipe 15 is movably installed inside the rotating pipe 14. A fixed plate 16 is welded to the side of the movable pipe 15. A cavity is opened inside the fixed plate 16. An opening 17 is opened on the fixed plate 16. The opening 17 discharges the gas inside the fixed plate 16 to the outside. When the fixed plate 16 stirs the sewage, the gas simultaneously enters the sewage to complete the aeration treatment.

[0026] In this embodiment, a through hole is opened on the side of the movable tube 15, which is connected to the cavity. A connecting tube 20 is movably installed at the bottom of the movable tube 15, and an aeration disc 18 is fixed on the connecting tube 20. A limit block 21 is fixed on the side of the movable tube 15. After the limit block 21 is movably installed inside the limit groove, the rotating tube 14 transmits the rotational force to the movable tube 15 through the limit block 21, so that the movable tube 15 moves up and down while completing the power output. A limit groove is opened on the rotating tube 14, and the limit block 21 is movably installed inside the limit groove. The movable tube 15 is installed inside the rotating tube 14 through a reset mechanism 22, which is a reset spring. The spring push keeps the movable tube 15 in constant contact with the connecting tube 20. The gas in the connecting tube 20 enters the interior of the movable tube 15 for aeration. The aeration disc 18 has an air outlet 19 and is movably mounted on the air inlet pipe 13. The bottom of the pool body 2 is fixed with a base plate. One end of the air inlet pipe 13 is fixed to the base plate. The connecting tube 20 has a connecting hole 23 and a ring seat 24 is fixed on the air inlet pipe 13. The ring seat 24 is in movable contact with one end of the connecting tube 20. The ring seat 24 provides a limit point for the descent of the aeration disc 18. Later, the aeration disc 18 can be removed from the connecting tube 20 when it moves upward. After the aeration disc 18 is removed, it can be cleaned or replaced.

[0027] Operating steps: During use, wastewater is injected into the tank 2 through the inlet pipe 11. The air pump inside the motor box 12 is started, and the air pump generates pressurized gas that enters the air inlet pipe 13. The gas inside the air inlet pipe 13 is injected into the movable pipe 15 and the aeration disc 18 through the connecting pipe 20. The gas enters the aeration disc 18 through the connecting hole 23. The gas inside the aeration disc 18 is discharged upward through the air outlet 19. When the gas is discharged through the air outlet 19, the drive motor 7 is started to drive the rotating pipe 14 and the movable pipe 15 to rotate. The rotating pipe 14 transmits the rotational force to the movable pipe 15 through the limit block 21, so that the movable pipe 15 moves up and down while completing the power output. The reset mechanism 22 keeps the movable pipe 15 in contact with the connecting pipe 20. Gas enters the interior of the movable tube 15 for aeration. The gas inside the movable tube 15 enters the interior of the fixed plate 16. The gas inside the fixed plate 16 is discharged again through the opening 17. When the fixed plate 16 rotates, it moves the gas, changing the position of the rising gas and thus changing the aeration point. The opening 17 discharges the gas inside the fixed plate 16 outward. While the fixed plate 16 is stirring the sewage, the gas simultaneously enters the sewage to complete the aeration treatment. After aeration is completed, the movable tube 15 is pushed upward, and the movable tube 15 squeezes the reset mechanism 22. Under the pressure of the reset mechanism 22, the movable tube 15 moves upward, and the bottom of the movable tube 15 separates from the connecting pipe 20. After separation, the aeration disc 18 is removed from the top of the air inlet pipe 13 for replacement or cleaning.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
