An anaerobic ammonia oxidation microbial denitrification treatment system

Abstract

This invention relates to an anaerobic ammonia oxidizing microbial denitrification system, comprising a tank, a separator connected to the tank, and multiple aeration heads disposed at the bottom of the tank. The system is characterized by a first protective mechanism disposed on the aeration heads to prevent anaerobic ammonia oxidizing bacteria sludge particles from adhering to and multiplying on the aeration heads, thus preventing blockage. By incorporating this first protective mechanism, the invention, through the combined action of a sealing component and an opening / closing component, ensures that the aeration heads remain in a closed environment when not in operation. Simultaneously, in the closed state, a cleaning component promptly disperses and discharges the sludge from the top of the aeration heads. This solves the technical problem that anaerobic ammonia oxidizing bacteria easily enter the micropores of the aeration heads during their reproduction process, leading to blockage, reduced aeration effect, slower reaction between anaerobic ammonia oxidizing bacteria sludge particles and wastewater, and decreased denitrification efficiency.

Description

Technical Field

[0001] This invention relates to the field of anaerobic ammonia oxidizing microbial denitrification technology, and more particularly to an anaerobic ammonia oxidizing microbial denitrification system. Background Technology

[0002] Ammonia nitrogen wastewater originating from fertilizer, coking, petrochemical, pharmaceutical, food, and landfill industries can cause eutrophication and black, foul-smelling water bodies if discharged into them. This increases the difficulty and cost of water treatment and can even be toxic to humans and other organisms. Treatment processes for ammonia nitrogen wastewater include anaerobic ammonia oxidation (AAO). AAO involves anaerobic ammonia-oxidizing bacteria reacting with ions in the wastewater to convert ammonia nitrogen into nitrogen gas, which is then removed. These bacteria play a vital role in the global nitrogen cycle and are therefore important in wastewater treatment.

[0003] Patent document CN109879429A discloses a biological treatment system and method for autotrophic denitrification wastewater based on anaerobic ammonia oxidation. The treatment system includes an inlet tank, a biological denitrification reactor, and an aeration system. The biological denitrification reactor is filled with a filter media layer. The aeration system is connected to the bottom of the biological denitrification reactor. The biological denitrification reactor is equipped with a reflux system. The inlet tank and the reflux system are connected to the bottom of the biological denitrification reactor.

[0004] However, in actual use, the inventors found that because the aeration head is completely exposed in the tank, when the device is not working, anaerobic ammonia oxidizing bacteria can easily enter the micropores of the aeration head during reproduction, causing the aeration head to become blocked. This weakens the aeration effect, slows down the reaction between the anaerobic ammonia oxidizing bacteria sludge particles and the sewage, and reduces the nitrogen removal efficiency. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting up a first protective mechanism, which includes a sealing component, an opening and closing component, and a cleaning component. Under the combined action of the sealing component and the opening and closing component, the aeration head can be in a closed environment when it stops working. At the same time, in the closed state, the cleaning component promptly disperses and discharges the sludge on the top of the aeration head. This solves the technical problem that anaerobic ammonia oxidizing bacteria can easily enter the micropores of the aeration head during reproduction, causing blockage of the aeration head, weakening the aeration effect, slowing down the reaction between anaerobic ammonia oxidizing bacteria sludge particles and sewage, and reducing nitrogen removal efficiency.

[0017] Preferably, the power assembly includes a bracket connected to the tank body and to which a sandwich plate is connected, a servo motor connected to the bracket and to which a drive gear is connected at its output end, a first follower gear and a second follower gear respectively connected to the second rotating rod and the fourth rotating rod, and an adjusting member respectively connected to the first follower gear and the second follower gear and used to cooperate with the drive assembly to adjust the position state of the first follower gear and the second follower gear.

[0018] The adjusting component includes a connecting column connected to the first follower gear and the second follower gear respectively, a receiving plate connected to the connecting column, and a first telescopic component connected between the receiving plate and the sandwich plate.

[0023] The beneficial effects of this invention are:

[0024] (1) In this invention, by setting a first protective mechanism, the first protective mechanism includes a sealing component, an opening and closing component and a cleaning component. Under the combined action of the sealing component and the opening and closing component, the aeration head can be in a closed environment when it stops working. At the same time, in the closed state, the sludge on the top of the aeration head is promptly flushed and discharged by the cleaning component. This solves the technical problem that anaerobic ammonia oxidizing bacteria can easily enter the micropores of the aeration head during the reproduction process, causing the aeration head to become blocked, the aeration effect to weaken, the reaction between the anaerobic ammonia oxidizing bacteria sludge particles and the sewage to slow down, and the nitrogen removal efficiency to decrease.

Under the action of the flow guiding component, the separated anaerobic ammonia oxidizing bacteria sludge particles can return to the bottom of the tank along the guiding direction and be evenly dispersed with the spiral drain pipe, fully combining with the sewage and improving the reaction efficiency.

[0027] (4) In this invention, by setting a second protective mechanism, when the device stops working and the aeration head is closed, the second protective mechanism starts to rotate back and forth under the drive of the power component, and cleans the top of the closed component and the bottom outlet of the spiral drain pipe by the cleaning brush, so as to prevent anaerobic ammonia oxidizing bacteria sludge particles from multiplying on the top of the closed component and to prevent sludge from clogging the bottom outlet of the spiral drain pipe.

[0028] In summary, this equipment has the advantages of thorough wastewater reaction, high purification efficiency, and effectively increased service life of aeration heads, making it particularly suitable for the field of anaerobic ammonia oxidation microbial denitrification treatment technology.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figure 1-2 and Figure 10-14 As shown, an anaerobic ammonia oxidation microbial denitrification treatment system includes a tank 100, a separator 200 connected inside the tank 100, and multiple aeration heads 300 disposed at the bottom of the tank 100, and further includes:

[0047] The first protective mechanism 1 is installed on the aeration head 300 and is used to prevent anaerobic ammonia oxidizing bacteria sludge particles from adhering and multiplying on the aeration head 300, which would cause the aeration head 300 to become blocked.

[0048] The first protective mechanism 1 includes a sealing component 11 disposed on the aeration head 300 and used to seal and protect the aeration head 300 when the reaction stops, an opening and closing component 12 disposed on the sealing component 11 and used to drive the sealing component 11 to open and close, and a cleaning component 13 disposed on the sealing component 11 and used to discharge the residual sludge inside after the sealing component 11 is closed.

[0049] In this embodiment, by setting a first protective mechanism 1, which includes a sealing component 11, an opening and closing component 12, and a cleaning component 13, the aeration head 300 can be in a closed environment when it stops working, under the combined action of the sealing component 11 and the opening and closing component 12. At the same time, in the closed state, the sludge on the top of the aeration head 300 is promptly dispersed and discharged by the cleaning component 13. This solves the technical problem that anaerobic ammonia oxidizing bacteria can easily enter the micropores of the aeration head 300 during reproduction, causing the aeration head 300 to become clogged, weakening the aeration effect, slowing down the reaction between the anaerobic ammonia oxidizing bacteria sludge particles and the sewage, and reducing the nitrogen removal efficiency.

[0050] In detail, when the wastewater enters the tank 100, the anaerobic ammonia oxidizing bacteria sludge particles mix with the wastewater under the action of the aeration head 300 and move upward while reacting under the action of bubble lift. After the reaction is completed, the purified water and the anaerobic ammonia oxidizing bacteria sludge particles enter the separator 200 together. Under the action of the separator 200, the purified water is discharged from the drain pipe, while the anaerobic ammonia oxidizing bacteria sludge particles are discharged from the bottom of the separator 200 and continue to be reused inside the tank 100. When the wastewater stops entering the tank 100, the sealing component 11 seals the aeration head 300 under the action of the opening and closing component 12. Then the cleaning component 13 introduces cleaning water to clean the top of the aeration head 300.

[0051] like Figure 2 and Figure 5-8 As shown, an anaerobic ammonia oxidizing microbial denitrification treatment system further includes a mixing mechanism 2 installed on the tank 100 and used to promote the full reaction of wastewater and anaerobic ammonia oxidizing bacteria sludge particles.

[0052] The mixing mechanism 2 includes a flow guiding component 21 disposed on the separator 200 for guiding the mixing of anaerobic ammonia oxidizing bacteria sludge particles with wastewater, and an agitation component 22 disposed on the separator 200 for agitating and dispersing the anaerobic ammonia oxidizing bacteria sludge particles deposited at the bottom of the tank 100.

[0053] In this embodiment, a mixing mechanism 2 is provided, which includes a flow guiding component 21 disposed on the separator 200 for guiding the anaerobic ammonia oxidizing bacteria sludge particles to mix with wastewater, and an agitation component 22 disposed on the separator 200 for stirring and dispersing the anaerobic ammonia oxidizing bacteria sludge particles deposited at the bottom of the tank 100. Under the action of the flow guiding component 21, the separated anaerobic ammonia oxidizing bacteria sludge particles can return to the bottom of the tank 100 along the guiding direction and be evenly dispersed with the spiral drain pipe 211, thus fully improving the reaction efficiency by combining with the wastewater.

[0054] In detail, the anaerobic ammonia oxidizing bacteria sludge particles separated by separator 200 fall from the bottom and are then guided by flow guide component 21 to the bottom of tank 100 and dispersed evenly along with the sewage. Finally, under the action of aeration head 300, they move upward again, and this cycle continues. During the process, stirring component 22 rotates at the bottom of tank 100, scraping up and dispersing some sludge particles attached to the bottom of tank 100, improving utilization and accelerating purification efficiency.

[0055] It should be noted that the anammox bacteria sludge particles have their own gravity and can fall in the sewage. However, after being treated by the separator 200, the anammox bacteria sludge particles are in a concentrated state. During the continuous operation of the aeration head 300, the air bubbles may lift the anammox bacteria sludge particles again as they fall, preventing them from fully contacting and reacting with the sewage from the bottom. This technical problem can be effectively solved by the flow guiding component 21.

[0056] Furthermore, such as Figure 6-8 As shown, the flow guiding assembly 21 includes a spiral drain pipe 211 connected to the end of the water inlet pipe 400, a flow guiding pipe 213 connected to the separator 200 and having multiple first through holes 212, a first rotating shaft 214 connected inside the flow guiding pipe 213, a propeller 215 connected to the first rotating shaft 214, a first rotating rod 216 connected to the flow guiding pipe 213, a first bevel gear 217 connected to the first rotating rod 216 and the first rotating shaft 214 respectively and meshing with each other, a second rotating rod 218 connected to the tank body 100, and a second bevel gear 219 connected to the second rotating rod 218 and the first rotating rod 216 respectively and meshing with each other. One end of the flow guiding pipe 213 is connected to the spiral drain pipe 211.

[0057] The agitation assembly 22 includes a third rotating rod 221 connected to the separator 200, a third bevel gear 222 connected to the first rotating rod 216 and the third rotating rod 221 respectively and meshing with each other, and a mounting rod 224 connected to the third rotating rod 221 and having multiple support legs 223.

[0058] In this embodiment, by setting a spiral drain pipe 211 connected to the end of the inlet pipe 400, the sewage is guided to the bottom of the tank 100 and discharged evenly through multiple drain holes, distributed at the bottom of the tank 100. At the same time, the impact force generated when the sewage enters impacts the anaerobic ammonia oxidizing bacteria sludge particles at the bottom of the tank 100, further accelerating the dispersion and upward movement of the anaerobic ammonia oxidizing bacteria sludge particles, while also promoting the reaction process between the sewage and the anaerobic ammonia oxidizing bacteria sludge particles.

[0059] In detail, when the control mechanism 4 drives the mixing mechanism 2, the aeration head 300 is opened and begins to work, the inlet pipe 400 is also opened, and sewage begins to flow in and is discharged through multiple drainage holes on the spiral drain pipe 211. Under the impact of the sewage, the anaerobic ammonia oxidizing bacteria sludge particles adhering to the bottom of the tank 100 are gradually dispersed. Then, the control mechanism 4 drives the second rotating rod 218 to rotate, and then drives the first rotating rod 216 to rotate through the second bevel gear 219. The first rotating rod 216 drives the first rotating shaft 214 to rotate through the first bevel gear 217. The first rotating shaft 214 drives the spiral... As the paddle 215 rotates, the anaerobic ammonia oxidizing bacteria sludge particles separated by the separator 200 move together with the sewage that enters the diversion pipe 213 through the first through hole 212. After passing through the diversion pipe 213 and the spiral drain pipe 211 in sequence, they are evenly dispersed again at the bottom of the tank 100. During the process, the first rotating rod 216 drives the third rotating rod 221 to rotate through the third bevel gear 222. The third rotating rod 221 drives the mounting rod 224 to rotate. Then, under the drive of the mounting rod 224, multiple support legs 223 rotate to stir the anaerobic ammonia oxidizing bacteria sludge particles at the bottom of the tank 100, promoting the mixing process.

[0060] It should be noted that the spiral drain pipe 211 is provided with multiple drain holes, and the direction of the multiple drain holes is all set towards the bottom of the tank 100.

[0061] like Figure 5 and Figure 9 As shown, an anaerobic ammonia oxidation microbial denitrification treatment system further includes a second protective mechanism 3 disposed on the tank 100 and used to prevent anaerobic ammonia oxidation bacteria sludge particles from adhering and multiplying on its top when the sealing component 11 is closed.

[0062] The second protective mechanism 3 includes a fourth rotating rod 32 connected to the tank 100 and connected to a drive gear 31, a drive gear ring 33 connected to the tank 100 and meshing with the drive gear 31, and a cleaning brush 34 connected to the drive gear ring 33.

[0063] In this embodiment, by setting a second protective mechanism 3, when the aeration head 300 closes after the device stops working, the second protective mechanism 3 starts to rotate back and forth under the drive of the power component 41, and cleans the top of the closed component 11 and the bottom outlet of the spiral drain pipe 211 by the cleaning brush 34, so as to prevent anaerobic ammonia oxidizing bacteria sludge particles from multiplying on the top of the closed component 11 and to prevent sludge from clogging the bottom outlet of the spiral drain pipe 211.

[0064] In detail, after the aeration head 300 closes and stops working, the control mechanism 4 switches the control object and starts to drive the second protection mechanism 3 to work. At this time, the control mechanism 4 drives the fourth rotating rod 32 to rotate, and then the fourth rotating rod 32 drives the drive gear 31 to rotate. The drive gear 31 drives the drive gear ring 33 that meshes with it to rotate. The drive gear ring 33 drives the cleaning brush 34 connected to its top to rotate. The cleaning brush 34 then cleans the top of the sealing component 11 and the bottom outlet of the spiral drain pipe 211 with the bristles set above and below.

[0065] It should be noted that, due to the obstruction of the fourth rotating rod 32, the cleaning brush only rotates back and forth within a certain angle to perform cleaning.

[0066] like Figure 1-3 As shown, an anaerobic ammonia oxidation microbial denitrification treatment system also includes a control mechanism 4 installed on the top of the tank 100 and used to alternately drive the mixing mechanism 2 and the second protective mechanism 3 to work.

[0067] The control mechanism 4 includes a power assembly 41 disposed on the tank 100 and used to provide power to the mixing mechanism 2 and the second protection mechanism 3, and a drive assembly 42 disposed on the power assembly 41 and used to adjust the control state.

[0068] In this embodiment, a control mechanism 4 is provided, which includes a power component 41 mounted on the tank 100 and used to provide power to the mixing mechanism 2 and the second protective mechanism 3, and a drive component 42 mounted on the power component 41 and used to adjust the control state. Under the action of the drive component 42, the power component 41 can alternately drive the first protective mechanism 1 and the second protective mechanism 3 to work, while controlling the opening and closing of the water inlet pipe 400, thereby enhancing the coordination of the working process.

[0069] In detail, when the inlet pipe 400 needs to be opened to start sewage treatment, the drive component 42 changes the transmission mode between itself and the power component 41, so that the inlet pipe 400 is opened. At the same time, the power component 41 can drive the mixing mechanism 2 to work. When the sewage treatment work needs to be stopped, the drive component 42 changes the transmission mode between itself and the power component 41 again, so that the power component 41 is disconnected from the mixing mechanism 2 and establishes a transmission relationship with the second protection mechanism 3, while closing the inlet pipe 400.

[0070] Furthermore, such as Figure 3-5 As shown, the power assembly 41 includes a bracket 412 connected to the tank body 100 and connected to a sandwich plate 411, a servo motor 414 connected to the bracket 412 and connected to a drive gear 413 at its output end, a first follower gear 415 and a second follower gear 416 respectively connected to the second rotating rod 218 and the fourth rotating rod 32, and an adjusting member 417 respectively connected to the first follower gear 415 and the second follower gear 416 and used to cooperate with the drive assembly 42 to adjust the position of the first follower gear 415 and the second follower gear 416.

[0071] The adjusting member 417 includes a connecting column 4171 connected to the first follower gear 415 and the second follower gear 416 respectively, a receiving plate 4172 connected to the connecting column 4171, and a first telescopic member 4173 connected between the receiving plate 4172 and the sandwich plate 411.

[0072] In this embodiment, by setting the adjustment component 417 in conjunction with the drive component 42, the power component 41 can switch the transmission object, thereby completing different work in the sewage treatment working state and the stop state, and further saving power resource costs.

[0073] In detail, when the water inlet pipe 400 is gradually closed, the drive assembly 42 presses down the support plate 4172 above the second follower gear 416, and the second follower gear 416 moves downward and meshes with the drive gear 413 at the output end of the servo motor 414 through the connecting column 4171. Conversely, when the water inlet pipe 400 is gradually opened, the drive assembly 42 presses down the support plate 4172 above the first follower gear 415, and the first follower gear 415 moves downward and meshes with the drive gear 413 at the output end of the servo motor 414 through the connecting column 4171. At the same time, the second follower gear 416 is reset under the action of the first telescopic member 4173.

[0074] It should be noted that the first follower gear 415 connected to the second rotating rod 218 and the second follower gear 416 connected to the fourth rotating rod 32 can both slide, but will rotate coaxially; the connecting column 4171 can move up and down, but will not rotate.

[0075] Furthermore, such as Figure 3-5 As shown, the drive assembly 42 includes a drive cylinder 422 connected to the bracket 412 and with the output end connected to the first rack 421, a first gear 424 connected to the bracket 412 via a second rotating shaft 423 and meshing with the first rack 421, a pressure rod 425 connected to the second rotating shaft 423, and an adjusting gear 427 connected to the gate valve 426 on the water inlet pipe 400 and meshing with the first rack 421 for transmission.

[0076] In this embodiment, by setting up the drive component 42, the power component 41 is simultaneously driven to change the transmission object during the process of adjusting the on / off state of the water inlet pipe 400, so that the various tasks are coordinated and orderly, and the work efficiency is effectively improved.

[0077] In detail, the drive cylinder 422 first retracts, driving the first rack 421 to move while simultaneously driving the first gear 424 and the adjusting gear 427 to rotate. The adjusting gear 427 opens the gate valve 426, causing the inlet pipe 400 to open and sewage to flow into the tank 100. Meanwhile, the first gear 424 drives the second rotating shaft 423 and the pressure rod 425 to rotate. The pressure rod 425 first releases the pressure on the top support plate 4172 of the first follower gear 415, and then begins to press down on the top support plate 4172 of the second follower gear 416, causing the second follower gear 416 to move down and mesh with the driving gear 413. The first follower gear 415 then moves up and releases its meshing with the driving gear 413. After the sewage treatment stops, the drive cylinder 422 extends, causing the inlet pipe 400 to close, and the upper and lower positions of the first follower gear 415 and the second follower gear 416 are exchanged again.

[0078] It should be noted that when the first follower gear 415 meshes with the drive gear 413, the servo motor 414 can drive the second rotating rod 218 to rotate through the first follower gear 415, thereby driving the mixing mechanism 2 to work. When the second follower gear 416 moves down and meshes with the drive gear 413, the servo motor 414 can drive the fourth rotating rod 32 to rotate through the second follower gear 416, thereby driving the second protection mechanism 3 to work.

[0079] Furthermore, such as Figure 10-13 As shown, the sealing assembly 11 includes a sealing ring 111 connected to the aeration head 300 and having multiple second through holes 110, multiple mounting plates 112 connected within the sealing ring 111, a slide block 113 connected to the mounting plate 112, a slide rail 115 connected to the slide block 113 and having a sealing plate 114 connected thereto, a second rack 118 connected to the sealing plate 114 and having teeth 117 connected to its end via a second telescopic member 116, and a second gear 119 connected to the mounting plate 112 and meshing with the second rack 118.

[0080] It is worth mentioning that the aeration head 300 can be in a relatively sealed environment by the combination of the sealing ring 111 and multiple sealing plates 114, which effectively prevents the anaerobic ammonia oxidizing bacteria sludge particles from multiplying on its surface and causing the micropores to become blocked.

[0081] In detail, when wastewater treatment begins, the agitator 22 starts working and drives the opening and closing assembly 12 to work. Then, the opening and closing assembly 12 drives the second gear 119 to rotate. The second gear 119 drives the second rack 118, which meshes with it, to move. The second rack 118 then drives the corresponding sealing plate 114 to move under the action of the slide rail 115 and the slide block 113, so that the aeration head 300 opens. When the sealing plate 114 is opened to the maximum position, the agitator 22 will intermittently drive the second gear 119 to rotate. The second gear 119 will continuously move the gear teeth 117. However, under the action of the second telescopic member 116, the gear teeth 117 will continuously reset. When the wastewater treatment work stops, the agitator 22 starts to reverse. By driving the second gear 119 to reverse, it will then cooperate with the gear teeth 117 connected to the second telescopic member 116 to reset the sealing plate 114, so that the aeration head 300 is sealed.

[0082] It should be noted that a sealing gasket is provided between the multiple sealing plates 114, and a damper is provided between the second gear 119 and the mounting plate 112 to prevent the sealing plates 114 from moving spontaneously and affecting the sealing effect.

[0083] Furthermore, such as Figure 10-13 As shown, the opening and closing assembly 12 includes a first toothed ring 121 connected to the sealing ring 111, a second toothed ring 122 connected inside the first toothed ring 121 and meshing with the second gear 119, a plurality of arc-shaped racks 123 connected to the support legs 223 and meshing with the first toothed ring 121, a stepped ring 124 disposed on the first rack 421 and cooperating with the sealing plate 114 to perform sealing work, and a plurality of shovel feet 125 connected to the first toothed ring 121.

[0084] In this embodiment, by setting an arc-shaped rack 123 connected to the support leg 223, the opening and closing component 12 can be driven by the stirring component 22 to work, thereby helping the closing component 11 to complete the automatic opening and closing work.

[0085] In detail, when the mounting rod 224 rotates, it drives multiple arc-shaped racks 123 to rotate. When the arc-shaped racks 123 rotate, they sequentially drive multiple first gear rings 121 to rotate. The first gear rings 121 drive the second gear rings 122 to rotate. Then, the second gear rings 122 drive the second gear 119 that meshes with them to rotate, thereby driving the sealing plate 114 to open. When sewage treatment stops, the mounting rod 224 reverses one revolution, thereby driving the sealing plate 114 to close. The stepped ring 124 and the sealing plate 114 adopt a physical seal to improve the sealing effect.

[0086] It should be noted that the opening or closing of the sealing plate 114 can be completed by the meshing and transmission of the arc-shaped rack 123 and the first toothed ring 121 in one operation. The shovel foot 125 plays a role in dispersing the surrounding anaerobic ammonia oxidizing bacteria sludge particles as it rotates with the first toothed ring 121.

[0087] Example 2

[0088] like Figure 12 and Figure 14 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0089] Furthermore, such as Figure 12 and Figure 14 As shown, the cleaning assembly 13 includes a third through hole 130 opened on the slide rail 115, a round plug 132 connected to the slide rail 115 by a spring 131 and located in the third through hole 130, a plurality of nozzles 133 connected to the sealing plate 114, and water flow channels 134 opened in the tank body 100, sealing ring 111, mounting plate 112, slide 113, sealing plate 114 and nozzles 133 and interconnected with each other.

[0090] It is worth mentioning that, since some sewage is sealed inside when the sealing component 11 is closed, in order to prevent the internal residue from affecting the aeration head 300, a cleaning component 13 is set up so that the sewage is discharged by injecting clean water when the aeration head 300 is sealed, thus ensuring the cleanliness of the aeration head 300 as much as possible.

[0091] In detail, when the sealing assembly 11 is fully closed, clean water is sprayed into the interior of the sealing assembly 11 through the interconnected water flow channels 134 opened in the tank 100, sealing ring 111, mounting plate 112, slide 113, sealing plate 114, and nozzle 133. While cleaning the top of the aeration head 300, it also drives the sewage to be discharged through the second through hole 110 on the sealing ring 111. When the sealing plate 114 is open, the sewage cannot enter the slide rail 115 by squeezing the round plug 132 due to the action of the spring 131. When the sealing plate 114 is closed, the water pressure of the clean water can push the round plug 132 up, so that the clean water enters the slide rail 115 through the water flow channel 134 in the slide 113, and then is guided to the multiple nozzles 133.

[0092] It should be noted that a one-way valve is installed in the second through hole 110 and the drainage pipe 213 to prevent sewage backflow, and the multiple nozzles 133 are set at a certain angle to increase the flushing effect.

[0093] Work process:

[0094] At the start of wastewater treatment, the drive assembly 42 changes the transmission method with the power assembly 41, opening the inlet pipe 400. Simultaneously, the power assembly 41 drives the mixing mechanism 2. First, driven by the power assembly 41, the agitator 22 disperses the anaerobic ammonia oxidizing bacteria sludge particles at the bottom of the tank 100 while simultaneously opening the closing assembly 11, exposing the aeration head 300 and initiating its operation. Then, the wastewater and the anaerobic ammonia oxidizing bacteria sludge particles move upwards together and react. Finally, under the action of the separator 200, the purified water is discharged from the drain pipe. The anaerobic ammonia oxidizing bacteria sludge particles separated by the separator 200 fall from the bottom and are then guided by the flow guide assembly 21 to the bottom of the tank 100, flowing with the wastewater... The particles are evenly dispersed and then move upward again under the action of the aeration head 300. This cycle continues. When the sewage treatment work needs to be stopped, the power component 41 drives the stirring component 22 to reverse one revolution, causing the opening and closing component 12 to drive the closing component 11 to close. Then, under the action of the cleaning component 13, the aeration head 300 is cleaned inside the closing component 11. After this, the drive component 42 changes the transmission mode with the power component 41 again, so that the power component 41 disconnects the transmission relationship with the mixing mechanism 2 and establishes a transmission relationship with the second protection mechanism 3. At the same time, the inlet pipe 400 is closed. Then, under the intermittent reciprocating rotation of the power component 41, the second protection mechanism 3 is driven to clean the top of the closing component 11 and the bottom outlet of the spiral drain pipe 211.
