Description
Technical Field
[0001] This invention relates to the field of wastewater treatment technology, specifically to a prefabricated energy-saving wastewater treatment equipment and method. Background Technology
[0002] Prefabricated energy-saving wastewater treatment, as an innovative and efficient wastewater treatment method, is gradually becoming an important part of modern environmental protection engineering. It cleverly integrates the concept of prefabricated buildings with energy-saving and environmental protection technologies, providing a brand-new approach to solving wastewater treatment problems. Through modular design, each treatment unit is prefabricated in the factory and then transported to the site for rapid assembly, greatly shortening the construction cycle and reducing construction difficulty. At the same time, the system focuses on energy conservation and consumption reduction, adopting advanced biological treatment technology and intelligent control system to ensure that the wastewater treatment process is efficient, stable, and low in energy consumption. This wastewater treatment method not only improves the efficiency and quality of wastewater treatment, but also effectively reduces the land area occupied and reduces the impact on the surrounding environment. Its intelligent management makes operation and maintenance easy and convenient, realizing the sustainable development of wastewater treatment. Whether for urban wastewater treatment or industrial wastewater treatment, prefabricated energy-saving wastewater treatment has shown broad application prospects and huge market potential.
[0003] Chinese patent document CN221093921U discloses a simplified prefabricated MBBR integrated wastewater treatment equipment, including an integrated box-type structure system; an inlet water distribution system located at the bottom of the integrated box-type structure system, which introduces the wastewater to be treated into the integrated box-type structure system; an air intake aeration system located at the bottom of the integrated box-type structure system, which provides gas into the integrated box-type structure system and mixes it with the wastewater; a suspended carrier and its support system located within the integrated box-type structure system, and above the inlet water distribution system and the air intake aeration system; the suspended carrier and its support system are equipped with suspended carriers, which, under the action of the gas provided by the air intake aeration system, fully contact the suspended carriers with the wastewater for purification treatment; and an effluent system located at the top of the integrated box-type structure system, connected to the suspended carrier and its support system, which discharges the treated wastewater.
[0004] During operation, a submersible pump pumps wastewater into the inlet pipe at a certain speed, which then flows into the integrated box-type structure system through the distribution pipe. The water distribution system ensures that the water flow is evenly and stably distributed at the bottom of the integrated box-type structure system. At the same time, a certain number of aeration branch pipes and aeration discs are arranged at the bottom of the integrated box-type structure system, covering the entire bottom. During operation, continuous aeration is carried out, allowing the air and water to mix thoroughly and flow upward. In the suspended carrier and its support system, the suspended carrier module floats up and down continuously under the impact of water and air mixing, making full contact with water and air. As a result, organic matter and other pollutants in the water are adsorbed and degraded by microorganisms on the surface of the suspended carrier, which greatly changes the water quality. Subsequently, the produced water treated by the suspended carrier module is collected and collected into the outlet pipe at the top of the integrated box-type structure system, from which the treated wastewater is discharged outside the integrated box-type structure system. The qualified effluent will be reused or discharged.
[0005] However, the above-mentioned patent documents also have the following shortcomings: When treating wastewater, the aerators in the sewage treatment equipment usually adopt elastic membrane aerators so that when the aerator is not in use, the aeration holes on the aeration membrane are in a blocked state to prevent wastewater from entering the aerator. However, after a long period of aeration, a large amount of dirt will remain on the surface of the aeration membrane. Initially, it is soft dirt, but with continuous fermentation, it easily turns into hard dirt, which leads to the clogging of the aeration membrane. Summary of the Invention
[0006] This invention provides a prefabricated energy-saving wastewater treatment equipment and method, aiming to solve the problem in related technologies that after aeration for a long time, a large amount of dirt remains on the surface of the aeration membrane. Initially, the dirt is soft, but it easily turns into hard dirt as it continues to ferment, thus causing the aeration membrane to be blocked.
[0007] The prefabricated energy-saving sewage treatment equipment of the present invention includes a prefabricated container and an aeration mechanism. The aeration mechanism is installed inside the prefabricated container and also includes a cleaning mechanism. The aeration mechanism includes an air collection pipe and multiple aeration heads, all of which are connected to the air collection pipe. Each aeration head includes an aeration channel, a shell, and an aeration membrane I. The aeration channel, shell, and aeration membrane I are connected in sequence, and a cavity I is formed between the aeration membrane I and the shell. The cleaning mechanism includes an elastic element, a support part, an elastic telescopic part, a fixing ring, an aeration membrane II, and a sealing element. The aeration channel is inserted into the air collection pipe and connected to the air collection pipe through the elastic element. The support part is connected inside the shell, and aeration membrane I contacts the support part. The elastic telescopic part is connected inside the air collection pipe and contacts the support part. Aeration membrane II is connected between the fixing ring and the shell. A cavity II is formed between the fixing ring, aeration membrane II, the shell, and the aeration channel. A through hole is provided on the aeration channel, and a sealing element is installed inside the aeration head to seal the through hole.
[0008] Beneficial effects: When treating wastewater with aeration, the aeration mechanism is activated to supply air into the air collection pipe. The air entering the air collection pipe is then delivered to the chambers of multiple aeration heads. After passing through the aeration membrane, the air forms small bubbles that enter the wastewater. Once the aeration membrane on the aeration head is blocked, the air entering the chamber pushes the aeration channel upward. As the aeration channel moves upward, it causes the shell, aeration membrane, support, and sealing components to move upward, stretching the elastic element and unfolding the aeration membrane. At this point, the telescopic end of the elastic telescopic part extends a certain distance and then stops moving. The support continues to move and separates from the telescopic end of the elastic telescopic part. When the air can no longer push the aeration channel upward, the aeration channel stops moving, and the chamber... The internal air pressure gradually increases, causing the aeration membrane 1 to deform and separate from the support. At this time, the air pressure in the cavity 1 drives the sealing component to open the through hole, allowing air from the cavity 1 to enter the cavity 2. The air entering the cavity 2 forms bubbles through the aeration membrane 2 and is then transported into the sewage for aeration treatment. After the air from the cavity 1 enters the cavity 2, the air pressure in the cavity 1 decreases, and the aeration membrane 1 gradually recovers and contacts the support. The elastic component pulls the aeration channel downward until the support collides with the telescopic end of the elastic telescopic part. After the collision between the support and the telescopic end of the elastic telescopic part, the support vibrates and transmits the vibration to the aeration membrane 1, thereby cleaning the dirt on the aeration membrane 1.
[0009] Preferably, a vertical rod is connected to the support part, and the vertical rod is connected to the aeration channel.
[0010] Its effect is that the support structure can be supported by the uprights.
[0011] Preferably, the elastic telescopic part is an elastic telescopic rod with the telescopic end facing upward and a compression spring built in it, and the compression spring inside the elastic telescopic part is in a compressed state.
[0012] Its effect is that, by compressing the spring inside the elastic telescopic part, when the aeration channel moves the support part upward, the telescopic end of the elastic telescopic part can move upward with the support part. After the telescopic end of the elastic telescopic part stops moving, the support part continues to move upward, so that the elastic telescopic part separates from the support part, shortening the distance between the telescopic end of the elastic telescopic part and the bottom of the support part, so as to avoid the support part not being able to collide with the telescopic end of the elastic telescopic part when it moves down to reset.
[0013] Preferably, the sealing component includes a lifting ring, an elastic part, and a sealing part. The lifting ring is sleeved on the upper outer side of the aeration channel. The elastic part is a compression spring and is connected between the lifting ring and the aeration channel. The sealing part is rotatably connected to the top of the aeration channel and is slidably connected to the lifting ring.
[0014] Its effect is that the increased air pressure inside the first chamber can push the lifting ring down, and the lifting ring can push the sealing part to flip so that the sealing part no longer blocks the through hole on the aeration channel, thereby allowing the air in the first chamber to enter the second chamber.
[0015] Preferably, the sealing part includes a ball and a rod, the rod is connected to the ball, the ball can be inserted into the through hole on the top of the aeration channel, the rod is rotatably connected to the top of the aeration channel, and the end of the rod away from the ball is slidably connected to the lifting ring for limiting.
[0016] Preferably, the outer side of the aeration channel is provided with a plug-in interface and a bayonet.
[0017] Preferably, it also includes auxiliary components including a connecting arm, a movable part, a second elastic part, a roller, a fixed part, a third elastic part, and a pushing part. The connecting arm is connected to the lifting ring, the movable part is inserted into the connecting arm, the second elastic part is connected between the connecting arm and the movable part, the roller is rotatably connected to the movable part and contacts the outside of the aeration channel, the third elastic part is connected between the fixed part and the fixed ring, the top end of the fixed part is inserted into the insertion interface on the outside of the aeration channel, and the pushing part is connected to the fixed part and is located in the bayonet.
[0018] Its effect is as follows: When the lifting ring moves downward due to the air pressure inside the cavity, it drives the connecting arm to move downward, which in turn drives the movable part, the second elastic part, and the roller to move downward. After the roller moves to the locking position outside the aeration channel, the second elastic part pushes the movable part to make the roller extend into the locking position and lock the lifting ring. The air pressure inside the cavity decreases, which causes the elastic element to pull the aeration channel downward, driving the sealing element downward. The lifting ring inside the sealing element then drives the connecting arm, the movable part, the second elastic part, and the roller to move downward. When the roller passes the pushing part, the pushing part guides the roller, causing the roller to disengage from the bayonet, thereby releasing the lock on the lifting ring. The elastic part then pushes the lifting ring to quickly reset, and drives the sealing part to seal the through holes on the aeration channel again, thereby disrupting the air pressure balance between cavity one and cavity two. This prevents the sealing part from being unable to seal the through holes on the aeration channel again due to the air pressure imbalance in cavity one and cavity two, thus preventing the vibration cleaning effect on aeration membrane one from failing.
[0019] Preferably, the connecting arm is L-shaped, and the elastic part is in a compressed state.
[0020] Preferably, the top of the pushing part is provided with a slope.
[0021] The present invention also provides a prefabricated energy-saving wastewater treatment method, which includes the following steps:
[0022] S1: Start the aeration mechanism to deliver air into the air collection pipe and then into multiple aeration heads, and the air passes through the aeration membrane into the sewage.
[0023] S2: After the first aeration membrane is blocked by dirt, the air delivered to the first cavity pushes the aeration channel upward. When the aeration channel moves upward, it stretches the elastic element and unfolds the second aeration membrane.
[0024] S3: The support moves and separates from the telescopic end of the elastic telescopic part. After the aeration channel stops moving, the air pressure inside the cavity increases, and the aeration membrane deforms and separates from the support.
[0025] S4: The air pressure inside cavity one increases and drives the sealing component to open the through hole, allowing the air inside cavity one to enter cavity two and pass through aeration membrane two into the sewage.
[0026] S5: The air pressure inside the cavity decreases, the aeration membrane recovers and comes into contact with the support, the elastic element pulls the aeration channel downward, and the support collides with the elastic extension part.
[0027] Beneficial effects: After the first aeration membrane is clogged with dirt, the air supply pipe continues to deliver air into the first cavity, which pushes the aeration channel upward. As the aeration channel moves upward, it moves the shell, the first aeration membrane, the support, and the sealing element upward, simultaneously pulling the elastic element and unfolding the second aeration membrane. At the same time, the telescopic end of the elastic telescopic part rises a certain distance and then stops moving, separating it from the support. After the aeration channel stops moving, the air supply pipe continues to deliver air into the first cavity, increasing the air pressure inside the cavity and driving the sealing element to stop the sealing element from moving. By sealing the through holes in the aeration channel, air in chamber one can enter chamber two through the through holes. The air is then divided into small bubbles by the aeration membrane two and transported into the sewage. After the air in chamber one is transported into chamber two, the air pressure decreases, and aeration membrane one gradually recovers and contacts the support. At this time, the aeration channel is pulled down by the elastic element until the support collides with the extension end of the elastic extension part. The collision between the support and the extension end of the elastic extension part generates vibration. The vibration on the support is transmitted to aeration membrane one, which can clean the dirt on aeration membrane one.
[0028] The beneficial effects of this invention are:
[0029] 1. When the first aeration membrane is clogged with dirt, the increased air pressure inside the first chamber causes the aeration channel to move upward, separating the first aeration membrane and the elastic telescopic part from the support part. This stretches the elastic element, causing the sealing part to open the through hole on the aeration channel, allowing air from the first chamber to enter the second chamber and be discharged outward through the second aeration membrane. After the air from the first chamber enters the second chamber, the air pressure inside the first chamber decreases, causing the elastic element to pull the aeration channel. The first aeration membrane then contacts the support part, and at the same time, the support part and the elastic telescopic part expand and vibrate. The vibration generated by the support part is transmitted to the first aeration membrane, thereby cleaning the first aeration membrane.
[0030] 2. The indirect air delivery of the second aeration membrane results in intermittent bubble formation as air passes through it. Workers can observe whether the bubbles rise intermittently to determine the number of blocked aeration heads, allowing them to decide whether to clean the aeration heads as needed. It also enables quick location of blocked aeration heads for cleaning. Attached Figure Description

[0041] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0042] like Figures 1 to 8 As shown, the prefabricated energy-saving sewage treatment equipment of the present invention includes a prefabricated container 1, an aeration mechanism 2, and a cleaning mechanism 3. The prefabricated container 1 includes a box body 18, and an anaerobic tank 11, an anoxic tank 12, and an aerobic tank 13 are arranged inside the box body 18. Sewage can pass through the anaerobic tank 11, the anoxic tank 12, and the aerobic tank 13 in sequence. The aeration mechanism 2 is installed in the aerobic tank 13, and the sewage in the aerobic tank 13 can be aerated through the aeration mechanism 2. The cleaning mechanism 3 is installed on the aeration mechanism 2, and the aeration mechanism 2 can be cleaned through the cleaning mechanism 3 to prevent the aeration mechanism 2 from being blocked by dirt in the sewage.
[0043] During use, the wastewater passes through the anaerobic tank 11 and the anoxic tank 12 in sequence before being transported to the aerobic tank 13. Then, the aeration mechanism 2 is activated to aerate the wastewater. At the same time, the cleaning mechanism 3 cleans the aeration mechanism 2 to prevent it from being blocked by dirt in the wastewater.
[0044] like Figure 1 and Figure 2 As shown, the prefabricated container 1 includes a container body 18, horizontal tie rods 14, vertical tie rods 15, an exhaust pipe 16, and an inlet pipe 17. The container body 18 contains an anaerobic tank 11, an anoxic tank 12, and an aerobic tank 13. The horizontal tie rods 14 and 15 are connected to the anoxic tank 12 and the aerobic tank 13, forming a biological carrier that optimizes the growth environment and metabolic efficiency of microorganisms, thereby improving the treatment effect. The upper left side of the container body 18 is connected to the inlet pipe 17, which is connected to the anaerobic tank. The anaerobic tank 11 is connected to the inlet pipe 17, which can transport sewage to the anaerobic tank 11 for treatment. Two transfer pumps are installed at the rear of the tank 18. One transfer pump can connect the anaerobic tank 11 and the anoxic tank 12, and the other transfer pump can connect the anoxic tank 12 and the aerobic tank 13, so that the sewage passes through the anaerobic tank 11, the anoxic tank 12 and the aerobic tank 13 in sequence. The exhaust pipe 16 is connected to the top of the tank 18 and is connected to the aerobic tank 13. The exhaust pipe 16 can discharge the gas in the aerobic tank 13.
[0045] When treating wastewater, the wastewater is first transported to the anaerobic tank 11 through the inlet pipe 17 for anaerobic treatment. After treatment, the wastewater in the anaerobic tank 11 is transported to the anoxic tank 12 through a transfer pump connected between the anaerobic tank 11 and the anoxic tank 12 for anoxic treatment. After anoxic treatment, the wastewater in the anoxic tank 12 is transported to the aerobic tank 13 through a transfer pump connected between the anoxic tank 12 and the aerobic tank 13 for aerobic treatment. During this process, the aeration mechanism 2 is activated to supply air to the aerobic tank 13, thereby performing aerobic treatment on the wastewater.
[0046] like Figures 1 to 3 As shown, the aeration mechanism 2 includes an aeration blower 21, an air collection pipe 22, an air extraction pipe 23, an air delivery pipe 24, and an aeration head 25. The aeration blower 21 is installed inside the anaerobic tank 11. The aeration blower 21 is a submersible blower. When the aeration blower 21 is started, the wastewater in the anaerobic tank 11 can cool and dissipate heat from the aeration blower 21. At the same time, the heat emitted by the aeration blower 21 can heat the reaction medium in the anaerobic tank 11. The air collection pipe 22 is installed inside the aerobic tank 13. The air extraction pipe 23 is connected to the air extraction end of the aeration blower 21. The end of the air extraction pipe 23 away from the aeration blower 21 extends to the outside of the housing 18. The air delivery pipe... The air supply pipe 24 is connected to the air supply end of the aeration blower 21. The end of the air supply pipe 24 away from the aeration blower 21 passes through the anoxic tank 12 and extends into the aerobic tank 13, and is connected to the air collection pipe 22. When the aeration blower 21 is started, it can draw in outside air through the air extraction pipe 23 and transport the air to the air collection pipe 22 through the air supply pipe 24. Multiple aeration heads 25 are set, and multiple aeration heads 25 are installed on the air collection pipe 22. The air entering the air collection pipe 22 can be transported to the sewage in the aerobic tank 13 through multiple aeration heads 25 and generate small bubbles, thereby aerating the sewage in the aerobic tank 13.
[0047] Continue to refer to Figures 1 to 3 As shown, the aeration head 25 includes an aeration channel 251, a shell 252, and an aeration membrane 253. The aeration channel 251 is installed on the air collection pipe 22 and is connected to the air collection pipe 22. The shell 252 is connected to the upper outer side of the aeration channel 251. The aeration membrane 253 is connected to the top of the shell 252. A cavity 254 is formed between the shells 252 and the aeration pipe 252. Air in the air collection pipe 22 enters the cavity 254 through the aeration channel 251 and can pass through the aeration membrane 253 to form multiple small bubbles. These small bubbles gradually float to the surface in the sewage, thereby aerating the sewage.
[0048] When aerating the wastewater in the aerobic tank 13, the aeration blower 21 is started, and air from the outside is drawn in through the air extraction pipe 23 and transported to the air collection pipe 22 through the air supply pipe 24. The air in the air collection pipe 22 enters the cavity 254 through the aeration channel 251. Then the air passes through the aeration membrane 253 and forms multiple small bubbles, which gradually float to the surface in the wastewater, thereby aerating the wastewater.
[0049] like Figure 2 , Figures 4 to 8 As shown, the cleaning mechanism 3 includes an elastic element 31, a support 32, a vertical rod 33, an elastic telescopic part 34, a fixing ring 35, an aeration membrane 36, a sealing element 37, and an auxiliary element 38. The aeration channel 251 is inserted into the air collection pipe 22. The elastic element 31 is a tension spring, which connects the aeration channel 251 and the air collection pipe 22. When the aeration membrane 253 is blocked by dirt, the continuous air flow from the air supply pipe 24 into the cavity 254 pushes the aeration channel 251 upward and stretches the elastic element 31. The support 32 is located inside the cavity 254, and the vertical rod 33 connects the support 32 and the aeration channel 251. The vertical rod 33 provides support for the support 32, which in turn supports the aeration membrane 253. The elastic telescopic part 34 is connected inside the air collection pipe 22. The top of the contraction part 34 contacts the bottom of the support part 32. The elastic telescopic part 34 is an elastic telescopic rod with the telescopic end facing upward and a compression spring inside. The elastic coefficient of the spring in the elastic telescopic part 34 is much smaller than the elastic coefficient of the elastic element 31. The spring in the elastic telescopic part 34 is in a compressed state. The fixing ring 35 is fixed on the air collection pipe 22. The second aeration membrane 36 is connected between the fixing ring 35 and the shell 252. A cavity 39 is formed between the fixing ring 35, the second aeration membrane 36, the shell 252 and the aeration channel 251. A through hole is provided on the aeration channel 251. The cavity 254 and the cavity 39 can be connected through the through hole on the aeration channel 251. The sealing member 37 is installed in the cavity 254. The sealing member 37 can block the through hole on the aeration channel 251 so that the cavity 254 and the cavity 39 are not connected.
[0050] After the aeration membrane 253 is blocked by dirt, air from the air supply pipe 24 continuously enters the cavity 254 to push the aeration channel 251 upward. When the aeration channel 251 moves upward, it drives the shell 252, the aeration membrane 253, the support 32, the upright 33, and the sealing member 37 upward, stretching the elastic member 31 and unfolding the aeration membrane 36. At this time, the telescopic end of the elastic telescopic part 34 moves upward by the push of its internal spring and continues to contact the bottom of the support 32. After the telescopic end of the elastic telescopic part 34 extends a certain distance, the internal spring stops pushing the telescopic end, causing it to separate from the support part 32. When air can no longer push the aeration channel 251 upwards, the aeration channel 251 stops moving, and the air pressure inside the cavity 254 gradually increases, causing the aeration membrane 253 to deform and separate from the support part 32. At this time, the air pressure inside the cavity 254 can drive the sealing member 37 to operate. The sealing element 37 is no longer used to block the through hole in the aeration channel 251, thereby connecting cavity one 254 and cavity two 39. After the connection between cavity one 254 and cavity two 39, air inside cavity one 254 enters cavity two 39 through cavity two 39 and is discharged into the sewage through aeration membrane two 36. After the air in cavity one 254 enters cavity two 39, the air pressure in cavity two 39 decreases, causing aeration membrane one 253 to gradually recover and come into contact with support part 32. At this time, under the action of the elastic part 372, the aeration channel 251 is pulled down, and the aeration channel 251 drives the shell 252, the aeration membrane 253, the support part 32 and the upright 33 to move down until the support part 32 collides with the telescopic end of the elastic telescopic part 34. After the collision between the support part 32 and the telescopic end of the elastic telescopic part 34, the support part 32 vibrates and transmits the vibration to the aeration membrane 253, thereby cleaning the dirt on the aeration membrane 253.
[0051] After the air pressure inside the cavity 254 decreases, the sealing member 37 will gradually reset and re-seal the through hole on the aeration channel 251, waiting for the air pressure inside the cavity 254 to increase again before opening the through hole on the aeration channel 251, thereby causing the support part 32 and the telescopic end of the elastic telescopic part 34 to collide frequently.
[0052] The auxiliary component 38 is connected to the sealing component 37. The auxiliary component 38 can disrupt the air pressure balance between the first cavity 254 and the second cavity 39, so as to avoid the air pressure balance in the first cavity 254 and the second cavity 39, which would prevent the sealing component 37 from sealing the through hole on the aeration channel 251 again, thereby avoiding the failure of the vibration cleaning effect on the aeration membrane 253.
[0053] Continue to refer to Figure 2 , Figures 4 to 8As shown, the sealing component 37 includes a lifting ring 371, an elastic part 372, and a sealing part 373. The lifting ring 371 is sleeved on the upper outer side of the aeration channel 251. The elastic part 372 is a compression spring and is connected between the lifting ring 371 and the aeration channel 251. The sealing part 373 is rotatably connected to the top of the aeration channel 251 and is slidably connected to the lifting ring 371. The sealing part 373 includes a ball and a rod. The rod is connected to the ball. The ball can be inserted into the through hole on the top of the aeration channel 251, thereby separating the first cavity 254 and the second cavity 39. The rod is rotatably connected to the top of the aeration channel 251, and the end of the rod away from the ball is slidably connected to the lifting ring 371.
[0054] When the air pressure inside cavity 254 increases, it can push the lifting ring 371 down and compress the elastic part 372. When the lifting ring 371 moves down, it can pull the rod to make the ball flip, so that the ball is separated from the through hole on the top of the aeration channel 251, thereby connecting cavity 254 and cavity 39. When the air inside cavity 254 enters cavity 39 and forms small bubbles at the aeration membrane 36 and is discharged into the sewage, the air pressure inside cavity 254 decreases. At this time, the elastic part 372 pushes the lifting ring 371 up, so that the lifting ring 371 pushes the rod to make the ball flip until the ball moves into the through hole on the top of the aeration channel 251, and separates cavity 254 and cavity 39 again.
[0055] Continue to refer to Figure 2 , Figures 4 to 8As shown, the auxiliary component 38 includes a connecting arm 381, a movable part 382, an elastic part 383, a roller 384, a fixing part 385, an elastic part 386, and a pushing part 387. The connecting arm 381 is connected to the lifting ring 371. One end of the connecting arm 381 passes through the outside of the aeration channel 251 and extends into the cavity 39. The connecting arm 381 is L-shaped. The movable part 382 is inserted into the end of the connecting arm 381 away from the lifting ring 371. The elastic part 383 is a compression spring and is connected between the connecting arm 381 and the movable part 382. The roller 384 is rotatably connected to the end of the movable part 382 that extends out of the connecting arm 381, and the roller 384 is rotatably connected to the outside of the aeration channel 251. The two elastic parts 383 are in a compressed state. The outer side of the aeration channel 251 is provided with an insertion interface and a bayonet. The bayonet is located below the roller 384. The insertion interface and the bayonet are connected. The fixing part 385 is inserted into the fixing ring 35. The elastic part 386 is a compression spring. The elastic part 386 is connected between the fixing part 385 and the fixing ring 35. The top of the fixing part 385 is inserted into the insertion interface on the outer side of the aeration channel 251. The pushing part 387 is connected to the fixing part 385 and is located in the bayonet. The top of the pushing part 387 is provided with an inclined surface for pushing the roller 384 so that the roller 384 disengages from the bayonet. The top of the pushing part 387 is in contact with the inner top wall of the bayonet.
[0056] When the aeration channel 251 moves upward, it causes the sealing component 37 to move upward. During this process, the lifting ring 371 drives the connecting arm 381, the movable part 382, the elastic part 383, and the roller 384 to move upward simultaneously. At the same time, the elastic part 386 pushes the fixed part 385 and the pushing part 387 upward. After the elastic force of the elastic part 386 is released, the fixed part 385 and the pushing part 387 stop moving, while the aeration channel 251 continues to move upward so that the top of the pushing part 387 separates from the inner top wall of the slot. When the lifting ring 371 moves downward due to the air pressure inside the cavity 254, it drives the connecting arm 381 downward, so that the connecting arm 381 drives the movable part 382, the elastic part 383, and the roller 384 downward. After the roller 384 moves to the slot outside the aeration channel 251, it is pushed upward by the elastic part 383. Part 382 allows roller 384 to extend into the bayonet, locking the lifting ring 371. After the air pressure inside cavity 254 decreases due to the connection between cavity 1 254 and cavity 2 39, elastic member 31 pulls aeration channel 251 downward, causing the aeration channel 251 to drive the sealing member 37 downward. When the sealing member 37 moves downward, it drives the connecting arm 381, movable part 382, elastic part 2 383, and roller 384 downward through the lifting ring 371. When the roller 384 passes the inclined surface on the pushing part 387, the inclined surface on the pushing part 387 guides the roller 384, causing the roller 384 to disengage from the bayonet, thereby releasing the lock on the lifting ring 371. Then, elastic part 1 372 pushes the lifting ring 371 to quickly reset, and drives the sealing part 373 to seal the through hole on the aeration channel 251 again.
[0057] After the first aeration membrane 253 is blocked by dirt, the second aeration membrane 36 can indirectly transport air, so that the bubbles formed by the air passing through the second aeration membrane 36 are formed intermittently. The staff can observe whether the bubbles rise intermittently to determine the number of blocked aeration heads 25, so as to determine whether the aeration heads 25 need to be cleaned according to the needs. The blocked aeration heads 25 can also be quickly located for cleaning.
[0058] Working principle:
[0059] First, the wastewater is transported to the anaerobic tank 11 through the inlet pipe 17 for anaerobic treatment. After treatment, the wastewater in the anaerobic tank 11 is transported to the anoxic tank 12 through a transfer pump connected between the anaerobic tank 11 and the anoxic tank 12 for anoxic treatment. After anoxic treatment, the wastewater in the anoxic tank 12 is transported to the aerobic tank 13 through a transfer pump connected between the anoxic tank 12 and the aerobic tank 13.
[0060] The aeration blower 21 is started, and air from the outside is drawn in through the air extraction pipe 23 and transported to the air collection pipe 22 through the air supply pipe 24. The air in the air collection pipe 22 enters the cavity 254 through the aeration channel 251. Then the air passes through the aeration membrane 253 and forms multiple small bubbles, which gradually float to the surface in the sewage, thereby aerating the sewage.
[0061] After the aeration membrane 253 is blocked by dirt, air from the air supply pipe 24 continuously enters the cavity 254 to push the aeration channel 251 upward. When the aeration channel 251 moves upward, it drives the shell 252, the aeration membrane 253, the support 32, the upright 33, and the sealing member 37 upward, stretching the elastic member 31 and unfolding the aeration membrane 36. At this time, the telescopic end of the elastic telescopic part 34 moves upward by the push of its internal spring and continues to contact the bottom of the support 32. After the telescopic end of the elastic telescopic part 34 extends a certain distance, the push of its internal spring no longer pushes the telescopic end, so that the telescopic end on the elastic telescopic part 34 separates from the support 32. After the air can no longer push the aeration channel 251 to continue to move upward, the aeration channel 251 stops moving, and the air pressure inside the cavity 254 gradually increases, so that the aeration membrane 253 deforms and separates from the support 32.
[0062] When the air pressure inside cavity 254 increases, it pushes the lifting ring 371 down and compresses the elastic part 372. When the lifting ring 371 moves down, it can pull the rod to rotate the ball, so that the ball is separated from the through hole on the top of the aeration channel 251, thereby connecting cavity 254 and cavity 39. The air inside cavity 254 enters cavity 39 and forms small bubbles at aeration membrane 36 before being discharged into the sewage.
[0063] When the lifting ring 371 moves downward due to the air pressure inside the cavity 254, it drives the connecting arm 381 to move downward, so that the connecting arm 381 drives the movable part 382, the elastic part 383 and the roller 384 to move downward. After the roller 384 moves to the latch outside the aeration channel 251, the elastic part 383 pushes the movable part 382 so that the roller 384 extends into the latch, thereby locking the lifting ring 371.
[0064] After the air inside cavity 254 enters cavity 39 and forms small bubbles at aeration membrane 36 before being discharged into the sewage, the air pressure inside cavity 254 decreases. At this time, elastic element 31 pulls aeration channel 251 downward, causing aeration channel 251 to drive sealing element 37 downward. When sealing element 37 moves downward, it drives connecting arm 381, movable part 382, elastic part 383, and roller 384 downward through lifting ring 371. When roller 384 passes the inclined surface on pushing part 387, the inclined surface on pushing part 387 guides roller 384, causing roller 384 to disengage from the jamming, thereby releasing the lock on lifting ring 371. Then, elastic part 372 pushes lifting ring 371 to quickly reset, and drives sealing part 373 to seal the through hole on aeration channel 251 again.
[0065] After the air pressure inside cavity 254 decreases, aeration membrane 253 gradually recovers and comes into contact with support 32. When aeration channel 251 moves downward, it drives shell 252, aeration membrane 253, support 32 and upright 33 to move downward until support 32 collides with the telescopic end of elastic telescopic part 34. After the collision between support 32 and the telescopic end of elastic telescopic part 34, support 32 vibrates and transmits the vibration to aeration membrane 253, thereby cleaning the dirt on aeration membrane 253.
[0066] The present invention also provides a prefabricated energy-saving wastewater treatment method, which includes the following steps:
[0067] S1: Start the aeration mechanism 2 to deliver air into the air collection pipe 22, and deliver it into multiple aeration heads 25 respectively, and pass through the aeration membrane 253 into the sewage;
[0068] Specifically, the aeration blower 21 is started, and air from the outside is drawn in through the air extraction pipe 23 and transported to the air collection pipe 22 through the air delivery pipe 24. The air in the air collection pipe 22 enters the cavity 254 through the aeration channel 251. Then the air passes through the aeration membrane 253 and forms multiple small bubbles, which gradually float to the surface in the sewage, thereby aerating the sewage.
[0069] S2: After the aeration membrane 253 is blocked by dirt, the air delivered to the cavity 254 pushes the aeration channel 251 upward. When the aeration channel 251 moves upward, it stretches the elastic element 31 and unfolds the aeration membrane 36.
[0070] Specifically, after the aeration membrane 253 is blocked by dirt, the air in the air supply pipe 24 continuously enters the cavity 254 to push the aeration channel 251 upward. When the aeration channel 251 moves upward, it drives the shell 252, the aeration membrane 253, the support 32, the upright 33 and the sealing part 37 to move upward, stretching the elastic part 31 and unfolding the aeration membrane 36.
[0071] S3: The support part 32 moves and separates from the telescopic end of the elastic telescopic part 34. After the aeration channel 251 stops moving, the air pressure inside the cavity 254 increases, and the aeration membrane 253 deforms and separates from the support part 32.
[0072] Specifically, the telescopic end of the elastic telescopic part 34 moves upward by the push of its internal spring and continues to contact the bottom of the support part 32. After the telescopic end of the elastic telescopic part 34 extends a certain distance, the push of its internal spring no longer pushes the telescopic end, so that the telescopic end on the elastic telescopic part 34 separates from the support part 32. After the air can no longer push the aeration channel 251 to continue to move upward, the aeration channel 251 stops moving, and the air pressure inside the cavity 254 gradually increases, so that the aeration membrane 253 deforms and separates from the support part 32.
[0073] S4: The air pressure inside cavity 254 increases and drives the sealing component 37 to open the through hole, allowing the air inside cavity 254 to enter cavity 39 and pass through aeration membrane 36 into the sewage.
[0074] Specifically, when the air pressure inside cavity 254 increases, it pushes the lifting ring 371 down and compresses the elastic part 372. When the lifting ring 371 moves down, it can pull the rod to rotate the ball, so that the ball is separated from the through hole on the top of the aeration channel 251, thereby connecting cavity 254 and cavity 39. The air inside cavity 254 enters cavity 39 and forms small bubbles at aeration membrane 36 before being discharged into the sewage.
[0075] When the lifting ring 371 moves downward due to the air pressure inside the cavity 254, it drives the connecting arm 381 to move downward, so that the connecting arm 381 drives the movable part 382, the elastic part 383 and the roller 384 to move downward. After the roller 384 moves to the latch outside the aeration channel 251, the elastic part 383 pushes the movable part 382 so that the roller 384 extends into the latch, thereby locking the lifting ring 371.
[0076] S5: The air pressure inside cavity 254 decreases, the aeration membrane 253 recovers and comes into contact with the support 32, the elastic element 31 pulls the aeration channel 251 down, and the support 32 collides with the elastic extension part 34.
[0077] Specifically, after air from inside cavity 254 enters cavity 39 and forms small bubbles at aeration membrane 36 before being discharged into the wastewater, the air pressure inside cavity 254 decreases. At this time, elastic element 31 pulls aeration channel 251 downward, causing aeration channel 251 to move sealing element 37 downward. When sealing element 37 moves downward, it drives connecting arm 381, movable part 382, elastic part 383, and roller 384 downward through lifting ring 371. When roller 384 passes the inclined surface on pushing part 387, the inclined surface on pushing part 387 guides roller 384, causing roller 384 to disengage from the jamming, thereby releasing the lock on lifting ring 371. Then, elastic part 372 pushes lifting ring 371 to quickly reset and causes sealing part 373 to seal the through hole on aeration channel 251 again.
[0078] After the air pressure inside cavity 254 decreases, aeration membrane 253 gradually recovers and comes into contact with support 32. When aeration channel 251 moves downward, it drives shell 252, aeration membrane 253, support 32 and upright 33 to move downward until support 32 collides with the telescopic end of elastic telescopic part 34. After the collision between support 32 and the telescopic end of elastic telescopic part 34, support 32 vibrates and transmits the vibration to aeration membrane 253, thereby cleaning the dirt on aeration membrane 253.
