Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment in breeding farms, and in particular to a wastewater treatment device in a beef cattle breeding farm. Background Art

[0002] The wastewater treatment device of beef cattle farm refers to a series of equipment and systems specially used to treat the wastewater generated by beef cattle farms. These wastewaters usually contain high concentrations of organic matter, suspended solids, ammonia nitrogen, pathogens and other pollutants. If they are discharged directly without treatment, they will cause serious pollution to the environment. Therefore, it is particularly important to use appropriate wastewater treatment devices to treat the wastewater from beef cattle farms.

[0003] As disclosed in CN117886458A, the invention relates to the technical field of sewage treatment, specifically a wastewater treatment device for a beef cattle farm, including an aeration tank for treating wastewater, an aeration pipeline is laid on the bottom surface of the aeration tank, a plurality of aeration components are arranged on the aeration pipeline, and an aeration component for supplying air to the aeration pipeline is arranged on the outside of the aeration tank; the aeration component includes an air connection pipe threadedly connected to the aeration pipeline, a vent pipe is arranged on the top of the air connection pipe for circumferential swinging, and a jet hood is fixedly installed on one end of the vent pipe away from the air connection pipe. By arranging the aeration component and the air control component, the effect of increasing the coverage of the jet hole by circumferential swinging of the jet hood is achieved to ensure that oxygen is fully mixed into the wastewater, so that one jet hood can replace multiple existing aeration nozzles, and at the same time, the size of the jet hole can be changed to ensure that oxygen is fully mixed into the wastewater, and the change of the air pressure inside the jet hood can be used to avoid the jet hole being blocked by suspended matter and particles.

[0004] In the above-mentioned prior art, wastewater is added to the treatment pool, and the air pump is started. The air pump transports oxygen to the aeration component, and then sprays it out through multiple aeration nozzles. During the jetting process, the jet nozzles move in multiple directions with the force generated by the jetting to ensure that the oxygen is fully mixed. However, there are pollutants in the wastewater. The fine pollutants will fill the gaps at the aeration nozzles, thereby affecting the deflection of the aeration nozzles. In addition, the gas sprayed from the aeration nozzles will rise rapidly in the wastewater, and a large amount of oxygen cannot be absorbed. In addition, the oxygen rises too fast and will wash away the microorganisms, thereby affecting the oxygen absorption of the microorganisms and the activity of the microorganisms. Summary of the invention

The irregular gear 29 drives a rack 27 to move, and a rack 27 drives the slide plate 28 to move, and a rack 27 drives the first gear 26 to deflect, and the first gear 26 drives the deflection air pipe 24 to deflect, and the deflection air pipe 24 drives the atomizing air nozzle 25 to deflect, so that oxygen is sprayed in multiple directions, thereby avoiding the obstruction of the deflection of the atomizing air nozzle 25 caused by a large amount of accumulated sediment, and the irregular gear 29 meshes with one rack 27 after the meshing is completed, and then meshes with another rack 27, so the two racks 27 move back and forth alternately, so that the atomizing air nozzle 25 can be deflected continuously.

[0038] Working principle: First, wastewater is added to the inside of the treatment tank 1 through the water inlet pipe, and the filter plate 11 at the top filters the incoming wastewater. When the addition of wastewater is stopped, the motor 211 and the air pump 21 are started. The air pump 21 generates negative pressure to transport it to the deflection air pipe 24, and finally sprays fine bubbles through the atomizing air nozzle 25.

At this time, the moving frame 31 drives the fixed frame 32, the moving baffle 315 moves, and the dispersing scraper teeth 317 move. The fixed frame 32 drives the leveling scraper 322 to flatten the garbage filtered on the treatment tank 1. The flattened garbage can cover the top of the filter plate 11, thereby blocking the discharged oxygen, reducing the speed of oxygen discharge, and facilitating the absorption of oxygen. The moving baffle 315 drives the fixed dispersing leaf 316 to move, and the moving baffle 315 cooperates with the filter plate 11 to block the bubbles, increasing the number of bubbles in the treatment tank 1 The time for the bubbles to stay in the wastewater is reduced, the flow speed of the bubbles is reduced, and the dissolved oxygen concentration in the wastewater is increased, so that the microorganisms have enough time to absorb more oxygen, thereby accelerating the metabolic activity of the microorganisms, thereby improving the treatment efficiency. Among them, the movable baffle 315 moves to one end and is squeezed and contacted with the treatment tank 1. The movable baffle 315 slides to the other side of the movable frame 31 after being pressed, thereby further blocking the bubbles, and the reciprocating movement of the movable baffle 315 and the fixed dispersion leaves 316 can stir the wastewater and the bubbles, so that the microorganisms can be evenly distributed and fully absorb oxygen to decompose the wastewater. When the wastewater treatment is completed, and the movable frame 31 is located on one side of the water inlet pipe, the turntable 326 continues to rotate to make the leveling scraper 322 contact with the filter plate 11.At this time, the movement of the moving frame 31 can drive the leveling scraper 322 to scrape the garbage on the treatment pool 1 and discharge it from the other side of the water inlet pipe, so as to facilitate cleaning.
