[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0015] (1) Existing wastewater treatment equipment only adds chelating agents and flocculants, while the present invention installs an aeration device in the treatment device. The aeration device uses ozone to overflow from the top of the ozone pipe and diffuse in the wastewater, which enhances the oxidation of harmful substances such as organic matter in the wastewater and improves the pretreatment effect of wastewater.

[0016] (2) The sieve cylinder is combined with the eccentrically set rotating cylinder. When the rotating cylinder rotates inside the sieve cylinder, because the center is eccentric and the diameter is smaller than the radius of the sieve cylinder, it can generate a stirring effect on the wastewater, which promotes the full collision and aggregation of flocs, improves the floc formation efficiency and quality. At the same time, the flocs can enter the space between the sieve cylinder and the treatment cylinder through the through holes on the outer periphery of the sieve cylinder. Larger flocs remain between the sieve cylinder and the rotating cylinder, realizing the preliminary classification treatment of flocs.

[0017] (3) The center of the rotating cylinder is eccentrically set with the center of the sieve cylinder and the diameter is smaller than the radius of the sieve cylinder, so that the rotating cylinder forms an asymmetric stirring flow field when it rotates in the sieve cylinder. This design breaks the uniform flow state of the traditional concentric rotation and generates a stronger turbulent effect through eccentric motion, which causes the floc particles in the wastewater to collide at high frequency and multiple angles during the movement, significantly improving the floc aggregation efficiency.

[0018] (4) The difference in centrifugal force generated by the eccentric rotation causes flocs of different particle sizes to form natural stratification in the radial distribution. Small-diameter flocs are close to the inner wall of the sieve cylinder and are discharged through the through holes, while large-diameter flocs are concentrated in the area near the rotating cylinder.

[0019] (5) The filter plate 1 inside the sieve cylinder and the annular filter plate between the sieve cylinder and the treatment cylinder, driven by cylinder 1 and cylinder 2, can intercept and finely filter the flocs at different positions. The annular filter plate is tightly attached to the inner side of the treatment cylinder and the outer periphery of the sieve cylinder, which can clean the flocs adhering to the inner side of the treatment cylinder, ensure efficient separation of wastewater and flocs, and improve the quality of effluent.

[0020] (6) In the cleaning device, the drive motor three drives the rotating shaft one and the cleaning component to rotate, which can sweep the flocs on the filter plate one and the annular filter plate into the groove one of the collection component. The cylinder four drives the sliding plate to slide, which can push the flocs to a specific position in the groove one, making it easy to collect them.

[0021] (7) The lifting and moving device realizes the flexible lifting and horizontal movement of the collection piece through the inverted U-shaped frame, guide rail II, servo motor II, cylinder III and other structures, so that the collection piece can be easily taken out from the processing cylinder, making it convenient for staff to clean the collected flocs, reducing the intensity of manual operation and improving the ease of equipment maintenance.

[0022] (8) The adsorption plates one, two and three in the adsorption assembly are all activated carbon plates, which have good adsorption performance and can effectively adsorb residual impurities in wastewater. The expansion of adsorption plates two and three can adjust the adsorption area according to the wastewater treatment requirements, thereby improving adsorption efficiency and targeting.

[0023] (9) Storage tank 1 and storage tank 2 store chelating agent and flocculant respectively. They are connected to the main addition pipe through addition pipe 1 and addition pipe 2. They are evenly released into the wastewater through multiple through holes 2 on the outer periphery of the feeding ring pipe. This allows the chelating agent to fully chelate with the rare earth ions in the wastewater to form a stable chelate. At the same time, the flocculant promotes the aggregation of suspended particles to form larger flocs, which improves the reaction efficiency and effect of the agent and the wastewater, laying a good foundation for subsequent treatment. The setting of the total flow meter, each extraction pump and flow meter can accurately control the amount and ratio of the agent added, avoid agent waste, and achieve precise dosing.

Since the center of the rotating cylinder 41 is eccentric to the center of the sieve cylinder 27 and its diameter is smaller than the radius of the sieve cylinder 27, it stirs the wastewater during rotation, causing the flocs to collide and aggregate fully. At the same time, the flocs enter the space between the sieve cylinder 27 and the treatment cylinder 1 through the through hole 3 on the outer periphery of the sieve cylinder 27. If the flocs are too large, they will remain between the sieve cylinder 27 and the rotating cylinder 41.

[0069] Drive motor four drives rotating shaft two 29 to rotate, and the adsorption components around rotating shaft two 29 rotate accordingly. Adsorption plates one 42, two 43, and three 44 are all activated carbon plates, and their axial length decreases sequentially. When not unfolded, their range is within the diameter of rotating cylinder 41. When drive motor four is turned on, cylinders six 47 and five 46 are turned on. Cylinder six 47 pushes connecting plate two 48, causing adsorption plate two 43 to extend, and cylinder five 46 pushes connecting plate one 45, causing adsorption plate three 44 to extend. The adsorption area can be adjusted according to the wastewater treatment requirements. After a period of time, cylinders five 46 and six 47 respectively drive adsorption plate three 44 and adsorption plate two 43 back to their initial positions, and then cylinders five 46, six 47, drive motor two, and drive motor four are turned off.

[0070] When cylinder 3, adsorption component 4, and cylinder 4 are activated, cylinder 3 pushes filter plate 30 to rise, intercepting larger particles of impurities in sieve cylinder 27; cylinder 4 pushes annular filter plate 31 to rise, which closely fits the inner side of treatment cylinder 1 and the outer periphery of sieve cylinder 27 during the rise, thus finely filtering the flocs that enter between sieve cylinder 27 and treatment cylinder 1. When the annular filter plate 31 and filter plate 30 rise to a certain distance above the sieve cylinder 27, cylinders 3 and 4 are closed, and the electric push rod is activated. The electric push rod drives the adsorption element 1 to contact the bottom of filter plate 30. The electric push rod and adsorption element 4 are closed, and adsorption element 1 is activated. Adsorption element 1 adsorbs filter plate 30. Cylinder 4 is activated, and cylinder 4 continues to push filter plate 30 and annular filter plate 31 until filter plate 30 contacts cleaning element 32. Cylinder 4 is closed, and drive motor 3 is activated. Drive motor 3 drives rotating shaft 28 and the outer cleaning element 32 to rotate, moving filter plate 30 and annular filter plate 31. The flocs are swept into the groove 1 inside the collection piece 36. When the rotating shaft 28 rotates at a certain angle, the drive motor 3 is turned off and the cylinder 4 38 is turned on. The cylinder 4 38 drives the sliding plate 39 to slide along the sliding hole, pushing the flocs on the side of the sliding plate 39 to the side of the groove 1 away from the sliding plate 39. That is, due to the rotation of the rotating cylinder 41, more flocs are located in a position close to the inside of the treatment cylinder 1. After the sliding plate 39 pushes back one stroke, the cylinder 4 38 is turned off and the drive motor 3 is turned on. After a period of time, the drive motor 3 is turned off and the water pump is turned on. The wastewater in the treatment cylinder 1 enters the nitrification treatment equipment through the outlet pipe under the action of the water pump for nitrification.

[0071] Cylinders 2 and 3 are activated. Cylinder 2 moves filter plate 30 and annular filter plate 31 downwards. When they reach a certain distance above the sieve cylinder 27, cylinder 2 closes. Adsorption element 4 is activated, adsorbing filter plate 30. Adsorption element 1 is then closed. The electric push rod is activated, returning adsorption element 1 to its initial position. The electric push rod is then closed. Cylinders 3 and 4 are activated, returning filter plate 30 and annular filter plate 31 to their initial positions. Cylinder 3 moves servo motor 35 and guide rail 33 upwards. After reaching a suitable position, cylinder 23 is closed. Servo motor 35 is activated, driving ball screw 3 to rotate, causing slider 34 to move collection element 36 upwards until it reaches above the processing cylinder 1. The cylinder is then closed. Servo motor 35 is activated, servo motor 25 is turned on, and servo motor 25 drives ball screw 2 to rotate, causing cylinder 3 23 to move the collection part 36 along guide rail 2 24. After moving to the appropriate position, the side of the collection part 36 contacts the adsorption part 3. Servo motor 25 is turned off, adsorption part 3 is turned on, and adsorption part 3 adsorbs the collection part 36. Adsorption part 2 is turned off (it is turned on when the collection part 36 contacts slider 3 34). Drive motor 17 is turned on, and drive motor 17 drives connector 18 to rotate the collection part 36 180°. Drive motor 17 is turned off, and servo motor 15 is turned on. Servo motor 15 drives ball screw 1 to rotate, causing the collection part 36 to move downward along guide rail 1 14 to the appropriate position. The staff then cleans the lint inside the collection part 36.
