The lower end of the duct is provided with an installation block, and the lower end of the installation block is provided with a connecting pipe. The connecting pipe is hollow inside, and the lower end of the connecting pipe is equipped with a connecting block.

[0004] While the aforementioned patent allows for the stretching of the flexible tube when the air duct at the top of the mounting block is lifted, facilitating the removal and cleaning of microporous diffusion columns without affecting the normal aeration of other microporous diffusion columns, it requires multiple aeration devices to achieve comprehensive aeration of the pond, resulting in high costs. Furthermore, it cannot recycle wastewater, and when the lower layer of water in the pond is over-aerated, the upper layer suffers from poor aeration due to the reduced oxygen levels in the lower and middle layers.

[0005] Therefore, this utility model provides a pond wastewater circulation aeration treatment device. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a pond wastewater circulation aeration treatment device, which solves the problems of needing to rely on multiple aeration devices to carry out comprehensive aeration treatment in the pond, resulting in high costs; in addition, it cannot circulate wastewater, and when the lower layer of the pond is over-aerated, the upper layer of the pond suffers from poor aeration due to the effect of the lower and middle layers of the pond on oxygen.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides two technical solutions:

[0021] Figures 1-4 The first embodiment is shown: a pond wastewater circulation aeration treatment device, including a support 1, a movable component 2 fixedly connected to the top of the support 1, an equipment plate 3 fixedly connected to the top surface of the movable component 2, an aeration component 4 fixedly connected to one side of the top surface of the equipment plate 3, and a circulation component 5 fixedly connected to the other side of the top surface of the equipment plate 3; the movable component 2 includes a slide groove 21 fixedly connected to the top of the support 1, a drive motor 22 sleeved inside one end of the slide groove 21, a lead screw 23 fixedly connected to the output end of the drive motor 22, a slider 24 threadedly connected to the surface of the lead screw 23, and an equipment plate 3 fixedly connected to the top surface of the slider 24.

[0022] Specifically, the drive motor 22 is started to drive the lead screw 23 to rotate, causing the threaded slider 24 to move horizontally along the inner wall of the chute 21, which in turn drives the equipment plate 3 and its aeration components 4 and circulation components 5 to move horizontally along the width of the pond. The vertical welding and fixing structure between the two ends of the chute 21 and the support 1 ensures that the horizontal movement trajectory is stable, so that a single set of aeration components 4 covers the entire pond area, replacing multiple fixed aeration devices.

[0023] In this embodiment, the circulation component 5 includes a circulation pump 51 fixedly connected to the top surface of the equipment plate 3. The water inlet end of the circulation pump 51 is connected to a water inlet pipe 52. The bottom end of the water inlet pipe 52 is fitted with a water inlet tank 53. The bottom surface of the water inlet tank 53 is provided with several sieve holes. The water outlet end of the circulation pump 51 is connected to a water outlet pipe 54. The bottom end of the water outlet pipe 54 is connected to a nozzle 55.

[0024] Specifically, when the aeration component 4 oxygenates the bottom water, the inlet tank 53 directly below draws oxygen-rich water through the screen holes distributed in a ring array on the bottom surface. After being pressurized by the circulation pump 51 through the inlet pipe 52, the water is delivered to the nozzle 55 extending to the surface of the pond through the outlet pipe 54 for spraying. This forces the high dissolved oxygen water at the bottom to mix with the low dissolved oxygen water at the surface, eliminating the problem of insufficient aeration in the upper layer caused by oxygen stratification.

[0025] Figures 1-4 The second embodiment is shown. The main difference from the first embodiment is that the screen holes on the bottom surface of the water inlet tank 53 are arranged in a ring array and the screen holes are located at the bottom end of the water inlet tank 53.

[0026] Specifically, the water inlet bucket 53 installed at the bottom of the water inlet pipe 52 has a ring-shaped array of screen holes on its bottom surface, and the screen holes completely cover the bottom area of ​​the water inlet bucket 53. During implementation, wastewater flows evenly from the bottom screen holes of the water inlet bucket 53. The ring-shaped array layout combined with the screen holes covering the entire bottom surface greatly increases the water intake per unit time. At the same time, the densely distributed screen holes effectively prevent debris at the bottom of the pond from clogging the water inlet pipe 52, ensuring that the circulating pump 51 continuously draws oxygen-rich water treated by the aeration component 4.

[0027] The water inlet tank 53 is located directly below the aeration component 4, and the nozzle 55 is located below the equipment plate 3 and extends to a position close to or at the surface of the pond water.

[0028] Specifically, the water inlet bucket 53 is vertically fixed directly below the aeration component 4, and the nozzle 55 extends from below the equipment plate 3 to a position 0-30cm from the pond surface. During implementation, the water inlet bucket 53 accurately draws the bottom high dissolved oxygen water that has just been treated by the aeration component 4. After being pressurized by the circulation pump 51, it is sprayed by the high-level nozzle 55 to form a water curtain, which forcibly mixes the bottom oxygen-rich water with the surface low-oxygen water. Through the vertical exchange of water, the dissolved oxygen stratification phenomenon is eliminated, and the dissolved oxygen balance of the entire pond is achieved.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Working principle: After the drive motor 22 starts, the drive screw 23 rotates in the slide groove 21, which drives the threaded slider 24 to move horizontally along the slide groove 21, so that the equipment plate 3 fixed on the top surface of the slider 24 and the aeration component 4 and circulation component 5 on it cover the width of the pond. At the same time, when the aeration component 4 oxygenates the bottom water of the pond, the water inlet tank 53 directly below efficiently extracts oxygen-rich water through the screen holes distributed in the annular array on the bottom surface. The wastewater is pressurized by the circulation pump 51 through the water inlet pipe 52 and then transported to the nozzle 55 extending to the surface of the pond through the water outlet pipe 54 to form a water curtain spray, which forces the bottom high dissolved oxygen water to mix with the surface water, eliminates the phenomenon of dissolved oxygen stratification, and realizes the synergistic effect of mobile aeration and vertical circulation of a single set of devices.
