DETAILED DESCRIPTION

[0022] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar symbols represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation to the present application.

[0023] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, which can be direct contact between the first and second features, or indirect contact through an intermediate medium. Moreover, the first feature "above", "over" and "on" the second feature can be directly above or obliquely above the first feature, or only means that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "under" and "under" the second feature can be directly below or obliquely below the first feature, or only means that the horizontal height of the first feature is less than that of the second feature.

[0024] In the field of wastewater treatment technology, most wastewater degradation treatment devices in actual use employ filters to filter wastewater. One or more filters are used for initial filtration before biodegradation or deep purification. However, during initial filtration, the wastewater often contains large impurities, which can easily lead to sludge buildup on the filters over time, reducing their filtration efficiency and the durability and practicality of the wastewater lifting device, while increasing manufacturing and maintenance costs. Furthermore, traditional filtration devices with one or more filters have fixed pore sizes, which cannot be dynamically adjusted according to actual needs, thus only filtering impurities of a single particle size. This design struggles to adapt to the diverse particle sizes of impurities in different batches of wastewater, resulting in unstable filtration and ultimately affecting overall wastewater treatment efficiency. Therefore, this invention develops a high-efficiency wastewater degradation treatment device that achieves timely cleaning of the filter screen and dynamic adjustment of the filter pore size through a series of innovative designs. The specific implementation method is as follows: Example 1: As Figures 1-3 The aforementioned high-efficiency wastewater degradation treatment device includes a wastewater treatment tank 1. A drive assembly 2 is installed at the bottom of the wastewater treatment tank 1. The drive assembly 2 is used to realize the reciprocating up-and-down movement of the filter screen. The drive assembly 2 includes a servo motor 21 fixedly installed at the bottom of the wastewater treatment tank 1. A drive sprocket 22 is fixedly installed on the output shaft of the servo motor 21. Rotary shafts 23 are symmetrically rotatably installed at the bottom of the wastewater treatment tank 1, and are rotatably connected to the bottom of the wastewater treatment tank 1. Driven sprockets 24 are fixedly installed on the lower surface of both rotating shafts 23. The driving sprocket 22 and the two driven sprockets 24 are on the same straight line. A chain 25 is meshed between the driving sprocket 22 and the two driven sprockets 24. Sliding grooves 26 are symmetrically opened on the inner side wall of the sewage treatment tank 1. The upper ends of the two rotating shafts 23 are provided with lead screws 27 inside the sliding grooves 26. The end of the lead screw 27 away from the rotating shaft 23 is rotatably connected to the top of the sliding groove 26. The surfaces of the two lead screws 27 are threaded with sliders 28. A filter assembly 3 is provided between the two sliders 28. The filter assembly 3 is used to perform preliminary filtration of the sewage inside the sewage treatment tank 1. When the external power supply is connected, the servo motor 21 is started. Through the transmission cooperation between the driving sprocket 22 and the chain 25, the driven sprockets 24 arranged symmetrically on both sides are driven to rotate synchronously. The two driven sprockets 24 drive the corresponding lead screws 27 to rotate inside the sliding groove 26 through their respective shafts 23. Since the lead screws 27 and the sliders 28 are connected by threads, the rotational motion is converted into the up-and-down reciprocating linear motion of the sliders 28 in the sliding groove 26. Finally, the two sliders 28, through linkage, drive the filter assembly 3 to achieve stable up-and-down reciprocating movement inside the sewage treatment tank 1, completing the dynamic execution of the filtration operation.

[0025] Furthermore, such asFigure 4 As shown, the filter assembly 3 includes a rectangular frame 31 disposed between two symmetrical sliders 28. An elastic scraper 32 is disposed between the outer ring of the rectangular frame 31 and the sewage treatment tank 1. The elastic scraper 32 can effectively prevent sewage from leaking along the edge of the rectangular frame 31 and can clean the inner wall of the sewage treatment tank 1 in real time, reducing the impact of dirt adhesion on the sewage treatment quality. It is suitable for scenarios where the rectangular frame 31 needs to move up and down frequently. The upper and lower ends of the rectangular frame 31 are respectively provided with an upper filter screen 33 and a lower filter screen 34. The upper filter screen 33 adopts square filter holes. Its corner structure has a stronger interception ability for larger and irregularly shaped impurities (such as fibers, debris, and block particles) under the same opening area. The "corners" of the square holes can increase the contact resistance between impurities and the filter screen, reducing the probability of large particles directly passing through the filter screen, playing a "coarse filtration" role. The lower filter screen 34 adopts circular filter holes. The circular structure of the holes is more regular and can more evenly control the hole size, which is suitable for "fine filtration" of fine particles and powdery impurities. After initial interception through the upper square holes, the remaining small particles pass through the circular holes. Due to the smooth edges of the holes, impurities accumulate and clog the openings, thus improving filtration accuracy. Both the upper filter screen 33 and the lower filter screen 34 are equipped with adjustment components 4 at their upper ends. These components allow for flexible adjustment of the filter screen's aperture. In actual use, domestic sewage may contain a mixture of hair, food scraps (large particles), silt, and colloids (small particles). Industrial wastewater (such as dyeing and chemical processing) may experience alternating increases in fibers, debris, or fine suspended solids depending on the production process. Different batches of wastewater have different particle sizes, requiring different sized filter screens for precise filtration to improve wastewater treatment efficiency.

[0026] During the movement of the upper filter screen 33 and the lower filter screen 34, relative motion occurs between the filter screen and the sewage. The water flow forms local turbulence due to the displacement of the filter screen, which can impact impurities (such as fibers and debris) attached to the surface of the filter screen. Impurities that are not completely embedded in the pores are carried away by the water flow, reducing the probability of "bridging" accumulation (i.e., impurities entangle and block multiple pores). Combined with the elastic scraper 32 in the equipment, the movement of the filter screen can drive the elastic scraper 32 to simultaneously clean the inner wall of the sewage treatment tank 1, forming a "movement-scraping" linkage cleaning effect.
