[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3 An industrial wastewater treatment device includes an oxidation tank 1 and a flotation tank 5 fixed on a frame. A discharge port 9 is provided on one side of the oxidation tank 1. A connecting pipe 6 is bolted into the discharge port 9 and is connected to the flotation tank 5. The connecting pipe 6 has a flow-limiting component inside. A lead screw 11 is rotatably connected to the top outer wall of the oxidation tank 1. A sliding plate 14 is threaded onto the outer side of the lead screw 11. A guide frame 12 is bolted to the top outer wall of the oxidation tank 1, and the sliding plate 14 is slidably connected to the guide frame 12. The guide frame 12 guides the sliding plate 14, allowing it to move stably up and down, thereby enabling the rotating rod 15 to move stably. A first motor is bolted to the top of the guide frame 12, and one end of the output shaft of the first motor is fixed to the lead screw 11. A second motor is bolted to the upper surface of the sliding plate 14, and the rotating rod 15 is rotatably connected to the bottom of the sliding plate 14. After wastewater treatment, the first motor is rotated in the reverse direction, causing the rotating rod 15 to move upward and reset, preventing rotation. The rotating rod 15 was damaged due to prolonged immersion in the oxidation tank 1. One end of the output shaft of the second motor was fixed to the rotating rod 15. An insertion port was provided at the top of the oxidation tank 1, and the rotating rod 15 was inserted into the insertion port. Multiple clearance slots 18 were provided on the outside of the rotating rod 15. Rotating plates 19 were rotatably connected inside the multiple clearance slots 18. Ferrous reagent and sodium hypochlorite solution were added to the oxidation tank 1 to mix and react with the wastewater. The rotation of the first motor caused the lead screw 11 to drive the slide plate 14 downward, thereby allowing the rotating rod 15 to enter the interior of the oxidation tank 1 through the insertion port. The rotation of the second motor caused the rotating rod 15 to unfold under the action of centrifugal force, and the rotating plate 19 gradually moved out of the clearance slots 18, thereby allowing the wastewater and the treatment raw materials to react fully and further degrade COD. Then, oxidation and retention were carried out. After the retention was completed, the blocking component was removed from the connecting pipe 6. The water in the oxidation tank 1 entered the flotation tank 5 through the connecting pipe 6. Alkali was added to the flotation tank 5 to adjust the pH, and then PAC and PAM were added. After sludge-water separation, the water was discharged in compliance with standards.

[0023] In this invention, it should be noted that both the oxidation tank 1 and the flotation tank 5 are internally fixed with a liquid distribution pipe 2 by bolts. Multiple nozzles 10 are installed at the bottom of the liquid distribution pipe 2. Through the cooperation of the liquid distribution pipe 2 and the nozzles 10, the liquid reactants are evenly discharged. The blocking component includes a spigot, which is located at the top of the connecting pipe 6. A baffle 17 is inserted into the spigot. An electric telescopic rod 16 is fixed to one side of the outer wall of the oxidation tank 1 by bolts, and the extended end of the electric telescopic rod 16 is fixed to the baffle 17. When the electric telescopic rod 16 retracts, it causes the baffle 17 to move upwards. At this time, the discharge port 9 is no longer blocked, and the water in the oxidation tank 1 flows through the connecting pipe 6. Pipe 6 enters the flotation tank 5. The top of the guide frame 12 is fixed with a limiting plate 13 by bolts, and the limiting plate 13 is located above the slide plate 14. The limiting plate 13 can limit the height of the slide plate 14 to prevent the slide plate 14 from moving excessively. The top of both the oxidation tank 1 and the flotation tank 5 are connected to a hopper 7. The top of the hopper 7 is rotatably connected to a cover plate 8. The cover plate 8 can protect the hopper 7 and prevent external impurities from entering the oxidation tank 1 through the hopper 7. A drain outlet is opened on one side of the flotation tank 5, and a drain pipe 4 is fixedly connected to the drain outlet. An inlet is opened on one side of the oxidation tank 1, and an inlet pipe 3 is fixedly connected to the inlet.

[0024] Working principle: When industrial wastewater needs to be treated, the pre-treated wastewater first enters the oxidation tank 1 through the inlet pipe 3. Ferrous reagent is added into the hopper 7 at the top of the oxidation tank 1, allowing the ferrous reagent to enter the oxidation tank 1. At the same time, the container containing sodium hypochlorite is connected to the separator pipe 2 on the oxidation tank 1, allowing the sodium hypochlorite solution to be sprayed into the oxidation tank 1 through the nozzle 10 on the separator pipe 2. This allows the ferrous reagent and sodium hypochlorite solution to mix and react with the wastewater. The first motor is started, and then the second motor is started. The rotation of the first motor causes the lead screw 11 to move the slide plate 14 downward, thereby allowing the rotating rod 15 to enter the oxidation tank 1 through the inlet. The second motor rotates, causing the rotating rod 15 to expand under centrifugal force, and the rotating plate 19 to gradually move out of the avoidance groove 18, thereby allowing the wastewater to fully react with the treatment raw materials, further degrading COD, and then undergoing oxidation and retention. After the retention is completed, the electric telescopic rod 16 is activated, and the electric telescopic rod 16 retracts, causing the baffle 17 to move upward. At this time, the discharge port 9 is no longer blocked, and the water in the oxidation tank 1 enters the flotation tank 5 through the connecting pipe 6. In the flotation tank 5, alkali is added to adjust the pH, and then PAC and PAM are added. After the sludge and water are separated and meet the standards, they are discharged through the drain pipe 4. After use, the first motor is rotated in reverse, causing the rotating rod 15 to move upward and reset.

[0025] Finally, it should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
