[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) Existing wastewater treatment equipment only adds chelating agents and flocculants. However, in the present invention, an aeration device is installed in the processing device. The aeration device overflows from the upper part of the ozone pipe with ozone and diffuses in the wastewater, enhancing the oxidation effect on harmful substances such as organic matter in the wastewater and improving the pretreatment effect of the wastewater. (2) The sieving cylinder cooperates with the eccentrically arranged rotating cylinder. When the rotating cylinder rotates in the sieving cylinder, due to the eccentricity of the center and the diameter being smaller than the radius of the sieving cylinder, it can stir the wastewater, prompting the flocs to fully collide and aggregate, improving the formation efficiency and quality of the flocs. At the same time, the flocs can enter the space between the sieving cylinder and the processing cylinder through the through holes three on the outer periphery of the sieving cylinder, while the larger flocs remain between the sieving cylinder and the rotating cylinder, realizing the preliminary classification treatment of the flocs. (3) The center of the rotating cylinder is eccentrically arranged with the center of the sieving cylinder, and the diameter is smaller than the radius of the sieving cylinder, so that an asymmetric stirring flow field is formed when the rotating cylinder rotates in the sieving cylinder. This design breaks the uniform flow state of traditional concentric rotation, generates a stronger turbulent effect through eccentric motion, and prompts the floc particles in the wastewater to collide at high frequencies and from multiple angles during the movement, significantly improving the floc aggregation efficiency. (4) The difference in centrifugal force generated by eccentric rotation causes flocs of different particle sizes to form a natural stratification in the radial distribution. The flocs with small particle sizes are close to the inner wall of the sieve cylinder and discharged through through-hole three, while the flocs with large particle sizes are concentrated in the area near the rotating cylinder. (5) The filter plate one inside the sieve cylinder and the annular filter plate between the sieve cylinder and the treatment cylinder can intercept and finely filter the flocs at different positions under the drive of cylinder one and cylinder two. The annular filter plate is closely attached to the inner side of the treatment cylinder and the outer periphery of the sieve cylinder, and can clean the flocs adhered to the inner side of the treatment cylinder, ensuring the efficient separation of wastewater and flocs and improving the effluent quality. (6) In the cleaning device, the drive motor three drives the rotating shaft one and the cleaning member to rotate, and can sweep the flocs on the filter plate one and the annular filter plate into the groove one of the collecting member. The cylinder four drives the sliding plate to slide, and can push the flocs to a specific position in the groove one for convenient centralized collection. (7) The lifting and moving device realizes the flexible lifting and horizontal movement of the collecting member through structures such as the inverted U-shaped frame, guide rail two, servo motor two, and cylinder three, enabling the collecting member to be conveniently taken out of the treatment cylinder, facilitating the staff to clean the collected flocs, reducing the manual operation intensity, and improving the maintenance convenience of the equipment. (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 the residual impurities in the wastewater. The unfolding of the adsorption plate two and the adsorption plate three can adjust the adsorption area according to the wastewater treatment requirements, improving the adsorption efficiency and pertinence. (9) The storage tank one and the storage tank two store the chelating agent and the flocculant respectively, and are connected to the adding main pipe through the adding pipe one and the adding pipe two. They are evenly released into the wastewater through multiple through-holes two on the outer periphery of the feeding annular pipe, enabling the chelating agent to fully chelate with the rare earth ions in the wastewater to form stable chelates. At the same time, the flocculant promotes the aggregation of suspended particles to form larger flocs, improving the reaction efficiency and effect of the medicament and wastewater, laying a good foundation for subsequent treatment. The setting of the total flowmeter, each extraction pump, and the flowmeter can accurately control the addition amount and proportion of the medicament, avoid medicament waste, and achieve precise dosing.

[0045] In the present invention, the first filter plate 30 is circular.

[0046] In the present invention, the water inlet pipe 11 can be connected to the rare earth chloride production equipment according to the on-site needs.

[0047] In the present invention, the extraction pump II 12, the flowmeter I 13, the water pump, the extraction pump III on the addition pipe I 7, the flowmeter III on the addition pipe I 7, the extraction pump III on the addition pipe II 8, the flowmeter III on the addition pipe II 8, the extraction pump I 9, the total flowmeter, the extraction pump IV 21, the flowmeter II 22, the drive motor II, the cylinder I 3, the cylinder II 4, the electric push rod, the suction attachment I, the suction attachment IV, the drive motor III, the servo motor III 35, the suction attachment II, the cylinder IV 38, the cylinder III 23, the servo motor II 25, the drive motor I 17, the suction attachment III, the servo motor I 15, the drive motor IV, the cylinder VI 47, and the cylinder V 46 are all communicatively connected to the controller.

[0049] The processing flow in the present invention is as follows: Turn on the extraction pump II 12 and the flowmeter I 13. The wastewater enters the treatment cylinder 1 through the water inlet pipe 11. According to the flow data real-time feedback by the flowmeter I 13, precisely control the input amount of the wastewater. After the wastewater enters the treatment cylinder 1 according to the set flow data, turn off the extraction pump II 12 and the flowmeter I 13. Turn on the extraction pump I 9 on the addition main pipe 10, the total flowmeter, the extraction pump III on the addition pipe I 7, the flowmeter III on the addition pipe I 7, the extraction pump III on the addition pipe II 8, and the flowmeter III on the addition pipe II 8. The extraction pump III respectively extracts the chelating agent from the storage tank I 5 and the flocculant from the storage tank II 6. The chelating agent and the flocculant are respectively merged into the addition main pipe 10 through the addition pipe I 7 and the addition pipe II 8. The total flowmeter monitors the total addition amount in real time to ensure that the two medicaments are mixed in a set ratio. The mixed medicament is uniformly released into the wastewater at the bottom of the treatment cylinder 1 through multiple through holes II on the outer periphery of the feeding loop pipe 40. Then turn off the extraction pump I 9 on the addition main pipe 10, the total flowmeter, the extraction pump III on the addition pipe I 7, the flowmeter III on the addition pipe I 7, the extraction pump III on the addition pipe II 8, and the flowmeter III on the addition pipe II 8.

[0050] Turn on the extraction pump IV 21 and the flowmeter II 22, and convey ozone to the ozone pipe. The ozone overflows from the upper opening of the ozone pipe and diffuses in the wastewater. Then turn off the extraction pump IV 21 and the flowmeter II 22. Turn on the drive motor II and the drive motor IV. The drive motor II drives the eccentrically arranged rotating cylinder 41 to rotate in the sieving cylinder 27. Since the center of the rotating cylinder 41 is eccentric with the center of the sieving cylinder 27 and its diameter is smaller than the radius of the sieving cylinder 27, the wastewater is stirred during the rotation process, promoting the flocs to fully collide and aggregate. At the same time, the flocs enter the space between the sieving cylinder 27 and the treatment cylinder 1 through the through holes III on the outer periphery of the sieving cylinder 27. If the flocs are too large, they will remain between the sieving cylinder 27 and the rotating cylinder 41. The drive motor four drives the rotation of the rotating shaft two 29, and the adsorption assembly on the outer periphery of the rotating shaft two 29 rotates accordingly. The adsorption plate one 42, the adsorption plate two 43, and the adsorption plate three 44 are all activated carbon plates, and their axial lengths decrease in sequence. When not unfolded, they are within the diameter range of the rotating cylinder 41. When the drive motor four is turned on, the cylinder six 47 and the cylinder five 46 are turned on. The cylinder six 47 pushes the connecting plate two 48, causing the adsorption plate two 43 to extend.
