[0028] The end of the hollow rod 2 away from the driving motor 3 is fixedly installed with a hollow cylinder 8, and a reciprocating thread is provided on the surface of the hollow cylinder 8. A slide plate 9 is threadedly sleeved on the hollow cylinder 8. A rotating plate 10 is installed in a sealed rotation at the end of the hollow cylinder 8 away from the hollow rod 2. The surface of the rotating plate 10 is symmetrically provided with through-holes. The side wall of the box body 1 is fixedly installed with two hollow round rods 12 with closed ends through two L-shaped connecting rods 11. A piston rod 13 is inserted into the hollow round rod 12 for sliding sealing. An air outlet is fixedly installed at the closed end of the hollow round rod 12. Tube 14, an air inlet pipe 15 is fixedly installed on the surface of the hollow rod 12, and the two air outlet pipes 14 are respectively sealed and inserted in the two through-holes. One end of the two piston rods 13 is fixedly connected to the surface of the slide 9, and a second one-way valve is provided in the air inlet pipe 15 and the air outlet pipe 14. The conduction direction of the second one-way valve in the air inlet pipe 15 is from the outside to the hollow rod 12, and the conduction direction of the second one-way valve in the air outlet pipe 14 is from the hollow rod 12 to the hollow cylinder 8. The water inlet pipe and the medicine inlet pipe are respectively fixedly mounted on the upper surface and the side wall of the box body 1.

[0029] First, the high-ammonia nitrogen wastewater to be treated is passed into the box body 1 from the water inlet pipe, and then the medicine is put into the box body 1 from the medicine inlet pipe. At this time, the drive motor 3 is started, and the output shaft of the drive motor 3 will drive the hollow rod 2, the hollow cylinder 8 and the multiple stirring rods 5 to rotate. The multiple stirring rods 5 will mix and stir the medicine and the high-ammonia nitrogen wastewater, and when the hollow cylinder 8 rotates, the slide 9 threadedly connected to the hollow cylinder 8 will drive the two piston rods 13 to move back and forth horizontally, and the volume inside the hollow round rod 12 will continue to change from small to large, and then from large to small. When the volume inside the hollow round rod 12 becomes large, the volume inside the hollow round rod 12 becomes large. When the pressure decreases, the gas in the outside will enter the hollow rod 12 from the air inlet pipe 15. When the volume inside the hollow rod 12 becomes smaller, the pressure increases, and the gas in the hollow rod 12 will enter the hollow cylinder 8 from the air outlet pipe 14, and then enter the hollow rod 2, and finally be squeezed out from the multiple air outlets 7 and enter the mixture of high ammonia nitrogen wastewater and drugs, so that bubbles are generated in the mixture of high ammonia nitrogen wastewater and drugs. When the bubbles burst, the turbulence effect can be achieved, thereby improving the uniformity and mixing process of the mixing of drugs and high ammonia nitrogen wastewater, and at the same time, the efficiency of wastewater treatment can also be accelerated.

[0030] A mounting plate 16 is fixedly installed in the box body 1, and a plurality of filter holes 17 are opened on the surface of the mounting plate 16. A plurality of rectangular plates 18 are provided below the mounting plate 16. Two adjacent rectangular plates 18 are fixedly connected by a connecting rod. A plurality of conical push rods 19 are fixedly installed on the upper surface of the rectangular plate 18. The push rods 19 are in a pointed cone shape so that the push rods 19 can more easily break the impurities accumulated in the filter holes 17. The plurality of push rods 19 correspond to the positions of the plurality of filter holes 17 respectively. The plurality of rectangular plates 18 are controlled to move vertically by a pressing assembly. The maximum diameter of the push rods 19 is smaller than the filter The aperture of the hole 17 allows high-ammonia nitrogen wastewater to pass smoothly through the filter hole 17 when the push rod 19 is located in the filter hole 17. The pressing assembly includes an inclined plate 20 and a trapezoidal plate 21. A rectangular opening is opened on the side wall of the box body 1, and a spring rod 22 is vertically fixedly installed on the bottom wall of the rectangular opening. A fixing rod 23 is fixedly installed on the top of the spring rod 22. One end of the fixing rod 23 is fixedly connected to the side wall of one of the rectangular plates 18, and the other end is fixedly connected to the inclined plate 20. The trapezoidal plate 21 is fixedly installed on the upper surface of the slide 9, and the inclined surface is in sliding contact with the inclined surface of the inclined plate 20.

[0031] When the high-ammonia nitrogen wastewater to be treated enters the box body 1 from the water inlet pipe, it will pass through multiple filter holes 17. The filter holes 17 can filter out larger impurities in the high-ammonia nitrogen wastewater. When the slide plate 9 is moving back and forth laterally, the trapezoidal plate 21 will also move together. The inclined surface of the trapezoidal plate 21 will slide in contact with the inclined surface of the inclined plate 20. When the trapezoidal plate 21 moves in the direction away from the box body 1, the inclined plate 20 will be pressed by the pressure of the trapezoidal plate 21 and will move up with multiple rectangular plates 18 and multiple push rods 19. The spring rod 22 will be stretched, and the multiple push rods 19 will pass through multiple filter holes 17 respectively, thereby pushing out the impurities accumulated in the filter holes 17 to avoid a large amount of impurities in the filter holes 17, which will cause serious blockage and affect the water permeability.

[0032] When the trapezoidal plate 21 moves toward the box body 1, the pressing force exerted by the trapezoidal plate 21 on the inclined plate 20 gradually decreases, and the inclined plate 20, the multiple rectangular plates 18 and the multiple push rods 19 will gradually move downward and reset under the action of their own gravity and the elastic potential energy of the spring rod 22. At this time, the multiple push rods 19 will move out of the multiple filter holes 17 respectively.

[0033] The upper and lower walls of the rectangular opening are vertically provided with sliding grooves, and the upper and lower surfaces of the fixing rod 23 are fixedly mounted with sealing plates 6, and the two sealing plates 6 are respectively slidably inserted into the two sliding grooves.

[0034] The two sealing plates 6 will move together with the fixing rod 23, thereby preventing the high-ammonia nitrogen wastewater in the box body 1 from flowing out from the rectangular opening.

[0035] In the present invention, firstly, the high-ammonia nitrogen wastewater to be treated is passed into the box body 1 from the water inlet pipe, and then the medicine is put into the box body 1 from the medicine inlet pipe. At this time, the driving motor 3 is started, and the output shaft of the driving motor 3 will drive the hollow rod 2, the hollow cylinder 8 and the multiple stirring rods 5 to rotate. The multiple stirring rods 5 will mix and stir the medicine and the high-ammonia nitrogen wastewater, and when the hollow cylinder 8 rotates, the slide 9 threadedly connected to the hollow cylinder 8 will drive the two piston rods 13 to move back and forth horizontally, and the volume inside the hollow round rod 12 will continuously change from small to large and then from large to small. When the volume inside the hollow round rod 12 When the volume increases, the pressure decreases, and the gas outside will enter the hollow round rod 12 from the air inlet pipe 15. When the volume inside the hollow round rod 12 decreases, the pressure increases, and the gas inside the hollow round rod 12 will enter the hollow cylinder 8 from the air outlet pipe 14, and then enter the hollow rod 2, and finally be squeezed out from multiple air outlets 7 and enter the mixture of high ammonia nitrogen wastewater and drugs, so that bubbles are generated in the mixture of high ammonia nitrogen wastewater and drugs. When the bubbles burst, the turbulence effect can be achieved, thereby improving the uniformity and mixing process of the mixing of drugs and high ammonia nitrogen wastewater, and at the same time, the efficiency of wastewater treatment can also be accelerated.

[0036] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
