The second filter plate 402 is arranged below the first filter plate 401, and both the first filter plate 401 and the second filter plate 402 are locked and slidably connected to the pretreatment frame 14. Inside the frame 3, and on both sides of the front of the pretreatment frame 3, fixed upright plates 403 are welded. A disassembly plate 404 is provided between the fixed upright plates 403. The disassembly plate 404 is engaged and slidably connected to the sides of the first filter plate 401 and the second filter plate 402. A locking plate 405 is engaged and connected to the bottom of the disassembly plate 404. Sealing gaskets are provided at the connection between the disassembly plate 404, the fixed upright plate 403, and the locking plate 405. The locking plate 405 is welded to the top of the feed hopper 2. The upper two sides of the disassembly plate 404 are fixedly connected to the front of the pretreatment frame 3 by bolts. The specific operation is as follows: the staff will respectively engage and slide the first filter plate 401 and the second filter plate 402 on the inner side of the pretreatment frame 3, and then engage the disassembly plate 404 between the fixed upright plate 403 from top to bottom, so that the bottom of the disassembly plate 404 engages with the engaging plate 405. Then, the upper two sides of the disassembly plate 404 are fixed to the front side of the pretreatment frame 3 with bolts. Subsequently, the staff will pour the multi-stage rare earth wastewater from the pretreatment frame 3 into the sedimentation tank 1. When passing through the first filter plate 401 and the second filter plate 402, it will undergo double filtration treatment to filter out impurities with larger diameters in the wastewater. After the wastewater that has passed the initial filtration enters the sedimentation tank 1, materials that facilitate the sedimentation of impurities in the wastewater will be added to the sedimentation tank 1 to accelerate the sedimentation rate of impurities in the wastewater, making it easier for the staff to use the multi-stage rare earth wastewater treatment device.

[0019] like Figure 1 and Figure 2 As shown, reaction tank 5 is located on one side of sedimentation tank 1, and a support plate 6 is fixedly connected between sedimentation tank 1 and reaction tank 5.

The inner walls of sedimentation tank 1 and reaction tank 5 are connected together. Each part is equipped with a stirring assembly 13, and the stirring assembly 13 includes a drive motor 1301, a rotating rod 1302 and a stirring element 1303. The drive motor 1301 is respectively installed on the side of the sedimentation tank 1 and the reaction tank 5, and the output shaft of the drive motor 1301 is fixedly connected to the rotating rod 1302 through a coupling. The ends of the rotating rod 1302 are rotatably connected to the sedimentation tank 1 and the reaction tank 5 respectively. The stirring element 1303 is fixedly connected to the outer wall of the rotating rod 1302. The aeration device 14 is installed at the bottom of the reaction tank 5 and is fixedly connected to the bottom of the reaction tank 5. The top of the reaction tank 5 is provided with a through hole, and a feeding pipe 15 is fixedly connected to one side of the top of the reaction tank 5. The specific operation is as follows: When the wastewater in the sedimentation tank 1 is settling, the stirring component 13 can be used to stir and mix the wastewater and materials. After stirring for a period of time, the mixing of materials is stopped. After a period of time, when the wastewater in the sedimentation tank 1 has finished settling, the pump 10 is used to extract liquid from the sedimentation tank 1, so that the liquid enters the outlet pipe 12 from the inlet pipe 11 and gradually enters the reaction tank 5. Then, the operator uses the feeding pipe 15 fixedly connected to one side of the top of the reaction tank 5 to add materials into the reaction tank 5, and then uses the stirring component 13 to stir and mix the materials, using the drive motor 1301. The rotating rod 1302 is driven to rotate, causing the stirring component 1303 fixedly connected to the outer wall of the rotating rod 1302 to rotate as well, thereby fully mixing the materials. During the material mixing process, the aeration device 14 set at the bottom of the reaction tank 5 is used to transport gas into the reaction tank 5, significantly increasing the dissolved oxygen concentration and providing the oxygen source necessary for the metabolism of aerobic microorganisms. In addition, the staff can open the valve of the sewage outlet 9 and use the electric push rod 7 to drive the push plate 8 to move, so that the material settled in the sedimentation tank 1 can be discharged from the sewage outlet 9, which facilitates the use of the multi-stage rare earth wastewater treatment device by the staff.

[0020] In summary, this multi-stage rare earth wastewater treatment device, based on Figures 1-3The structure shown in the diagram, during the use of the multi-stage rare earth wastewater treatment device, firstly, the operator engages and slides the first filter plate 401 and the second filter plate 402 onto the inner side of the pretreatment frame 3. Then, from top to bottom, the disassembly plate 404 is engaged between the fixed upright plate 403, with the bottom of the disassembly plate 404 engaging with the engaging plate 405. Bolts are then used to fix the upper sides of the disassembly plate 404 to the front side of the pretreatment frame 3. Subsequently, the operator pours the multi-stage rare earth wastewater from the pretreatment frame 3 into the sedimentation tank 1. The wastewater undergoes double filtration through the first filter plate 401 and the second filter plate 402, filtering out larger diameter impurities. After the pre-filtered wastewater enters the sedimentation tank 1, materials that facilitate the sedimentation of impurities are added to accelerate the sedimentation rate. During sedimentation in the sedimentation tank 1, the stirring component 13 can be used to mix the wastewater and materials. After stirring for a period of time, the mixing of materials is stopped. After a period of time, the sedimentation tank... When the wastewater in sedimentation tank 1 has finished settling, the pump 10 is used to extract liquid from sedimentation tank 1, so that the liquid enters from the inlet pipe 11 into the outlet pipe 12 and gradually enters the reaction tank 5. Then, the staff adds materials into the reaction tank 5 through the feed pipe 15 fixedly connected to one side of the top of the reaction tank 5. The stirring component 13 is then used to stir and mix the materials. The drive motor 1301 drives the rotating rod 1302 to rotate, so that the stirring component 1303 fixedly connected to the outer wall of the rotating rod 1302 rotates accordingly, thereby fully mixing the materials. During the material mixing process, the aeration device 14 set at the bottom of the reaction tank 5 is used to transport gas into the reaction tank 5, which significantly increases the dissolved oxygen concentration and provides the oxygen source necessary for the metabolism of aerobic microorganisms. In addition, the staff can open the valve of the sewage outlet 9 and use the electric push rod 7 to drive the push plate 8 to move, so that the settled materials in sedimentation tank 1 can be discharged from the sewage outlet 9, which facilitates the use of the multi-stage rare earth wastewater treatment device.
