[0025] like Figs. 1-3 As shown, the present invention proposes an ammonia nitrogen wastewater treatment device, which includes an aeration tank 1, and an aeration mechanism 2 is provided inside the aeration tank 1.

[0026] In this invention, the circulating water in the phosphate workshop can be placed in the aeration tank 1. After the water enters the interior of the aeration tank 1, the wastewater can be aerated by the aeration mechanism 2, so that the wastewater can fully contact the air, thereby removing ammonia nitrogen from the wastewater and achieving the purpose of reducing ammonia nitrogen in the circulating water.

[0027] In an optional embodiment, the aeration mechanism 2 includes a compressed air pump 21, a connecting pipe 22, a first electric valve 23, a diverter pipe 24, a main aeration pipe 25, an aeration assembly 26, and a backwashing assembly 27. The compressed air pump 21 is located on the left side of the aeration tank 1. The connecting pipe 22 is connected to the air outlet of the compressed air pump 21. The first electric valve 23 is located inside the connecting pipe 22. The diverter pipe 24 is connected to the end of the connecting pipe 22 away from the compressed air pump 21. The main aeration pipe 25 is connected to the side of the diverter pipe 24 away from the connecting pipe 22. The other end of the main aeration pipe 25 extends into the interior of the aeration tank 1. The aeration assembly 26 is located outside the main aeration pipe 25. The backwashing assembly 27 is located on the left side of the aeration tank 1.

[0028] It should be noted that when wastewater needs to be treated, the first electric valve 23 is opened, the compressed air pump 21 is started, and gas is sent into the connecting pipe 22. The connecting pipe 22 sends air into the interior of the diversion pipe 24, and the diversion pipe 24 sends air into the interior of the aeration main pipe 25. The wastewater is aerated through the aeration components 26 on the outside of the aeration main pipe 25. At the same time, during the aeration process, the aeration components 26 can make full contact between the air and the wastewater. During the aeration process, the wastewater can form small vortices, increasing the water flow and further improving the contact effect between the water and the air, thereby improving the efficiency of removing ammonia nitrogen from the water. When aeration is not performed, impurities in the wastewater may clog the aeration components 26, thereby affecting the aeration effect of the aeration components 26. The backwashing component 27 can backwash the aeration components 26 to remove impurities inside the aeration components 26 and ensure the aeration effect of the aeration components 26.

[0029] In one optional embodiment, there are multiple aeration main pipes 25, all of which extend into the aeration tank 1 and are evenly distributed. There are multiple sets of aeration components 26, all of which are located on the outside of the aeration main pipes 25 and are evenly distributed.

[0030] It should be noted that the wastewater can be fully aerated by multiple sets of aeration main pipes 25 and multiple sets of aeration components 26, thereby ensuring that the wastewater has sufficient contact with the air and further ensuring the removal of ammonia nitrogen from the wastewater as much as possible.

[0031] In an optional embodiment, the aeration assembly 26 includes an aeration branch pipe 261, a nozzle 262, and a baffle 263. The aeration branch pipe 261 is connected to the outside of the main aeration pipe 25 and is vertically installed inside the aeration tank 1. The nozzle 262 is connected to the outside of the aeration branch pipe 261, and the baffle 263 is located on the outside of the aeration branch pipe 261.

[0032] It should be noted that during aeration, air enters the interior of the aeration branch pipe 261 through the aeration main pipe 25 and is ejected through the nozzle 262 on the outside of the aeration branch pipe 261. When the gas is ejected, it can aerate the sewage.

[0033] In addition, the end of the nozzle 262 away from the aeration branch pipe 261 is tilted downwards, and the baffle plate 263 is located on the outside of the aeration branch pipe 261 and is tilted. The end of the nozzle 262 away from the aeration branch pipe 261 corresponds to the baffle plate 263. When the gas is sprayed out through the nozzle 262, some of the gas will form bubbles. When the bubbles are sprayed out, they will come into contact with the baffle plate 263, thereby making the bubbles break as much as possible and making the air and water come into full contact. At the same time, the tilt angle of the baffle plate 263 is 45 degrees. When the gas passes over the top of the baffle plate 263, it will be tilted. Under the drive of the gas, the sewage near the baffle plate 263 will form small vortices, thereby increasing the fluidity of the sewage and further improving the contact effect between the sewage and the air, thus improving the sewage treatment effect.

[0034] The nozzle 262 is tilted downwards at the end away from the aeration pipe 261, which allows the gas to be sprayed downwards. As the gas is discharged from the sewage, the distance the gas travels is increased, thereby increasing the contact time between the air and the sewage and further improving the sewage treatment efficiency.

[0035] In an optional embodiment, there are multiple sets of nozzles 262 and baffles 263, and the multiple sets of nozzles 262 and baffles 263 are all located on the outside of the aeration pipe 261 and are spirally distributed.

[0036] It should be noted that the threaded nozzles 262 and the baffles 263 can cause the sewage to flow to a certain extent during aeration, thereby ensuring the treatment effect of sewage in areas not directly aerated, and greatly improving the aeration effect and treatment efficiency of sewage.

[0037] In an optional embodiment, the backwashing assembly 27 includes a water pump 271, an outlet pipe 272, and a second electric valve 273. The water pump 271 is located on the left side of the aeration tank 1, the outlet pipe 272 is connected to the outlet of the water pump 271, and the end of the outlet pipe 272 away from the water pump 271 is connected to the inside of the connecting pipe 22. The first electric valve 23 is located on the left side of the outlet pipe 272, and the second electric valve 273 is located inside the outlet pipe 272.

[0038] It should be noted that when the aeration branch pipe 261 or the nozzle 262 is blocked by impurities, the first electric valve 23 is closed, and the second electric valve 273 and the water pump 271 are opened. The inlet of the water pump 271 is connected to the water source through the pipe body. The water pump 271 draws water and sends it into the interior of the connecting pipe 22 through the outlet pipe 272. Then it will be sprayed out through the diversion pipe 24, the main aeration pipe 25, the aeration branch pipe 261 and the nozzle 262, and the water will flush the interior of the aeration branch pipe 261 and the nozzle 262, thus avoiding the problem of blockage of the aeration branch pipe 261 and the nozzle 262 affecting the aeration effect of sewage.

[0039] In an optional embodiment, an inlet pipe 3 is connected to the top left side of the aeration tank 1, and a drain pipe 4 is connected to the bottom right side of the aeration tank 1.

[0040] It should be noted that wastewater can be sent into the aeration tank 1 through the inlet pipe 3, and the treated water can be discharged through the outlet pipe 4. A controller is installed on the outside of the aeration tank 1. The compressed air pump 21, the first electric valve 23, the water pump 271 and the second electric valve 273 are all electrically connected to the controller. The controller can control the compressed air pump 21, the first electric valve 23, the water pump 271 and the second electric valve 273.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
