[0010] Further, guide wheels are fixedly installed at the corners of the lifting seat, and the guide wheels are in rolling contact with the outer wall of the fixed frame of the membrane assembly.

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Example 1, referring to Figures 1-7This invention provides an integrated wastewater treatment device, comprising an aerobic reaction tank 1, an aeration tank 2, and a clear water tank 3. A membrane module 4 is installed in the aeration tank 2, and an aeration module 5 is installed at the bottom of the membrane module 4. A lifting seat 6 is vertically slidably connected to the fixing frame of the membrane module 4. Multiple aeration guide elements 8 are linearly and equally spaced on the top surface of the lifting seat 6, and a suspension mechanism is installed on the bottom surface of the lifting seat 6. Each aeration guide element 8 includes a guide plate 81 fixedly connected to the lifting seat 6. A retaining plate 82 is connected to both symmetrical sides of the guide plate 81. Multiple guide grooves 83 are opened on the side of the guide plate 81 opposite to the retaining plate 82. The guide groove 83 of plate 81 and the guide groove 83 of card plate 82 cooperate to form a guide hole. The membrane filament of membrane module 4 is placed in the corresponding guide hole. Two inclined surfaces are symmetrically opened at the bottom of guide plate 81. The suspension mechanism includes suspension component 10 and air control component 11. Suspension component 10 includes a diversion pipe 101. Both ends of the diversion pipe 101 are connected to airbags 102. The airbags 102 are fixedly connected to the bottom of lifting seat 6. The remaining end of the diversion pipe 101 is connected to the air supply pipe of aeration component 5 by a hose 103. The air control component 11 is installed on the pipe wall of diversion pipe 101 and is used to control the air supply switch state of diversion pipe 101.

[0039] Specifically, wastewater is degraded by microorganisms in aerobic reaction tank 1 and then flows into aeration tank 2. Membrane module 4 is connected to an external suction pump, which creates suction at the membrane fibers, introducing the treated clean water into clear water tank 3. The air supply pipe continuously supplies air to aeration module 5, and the generated bubbles, as they rise, initially wash the sludge on the surface of the membrane fibers. At the same time, the gas output from the air supply pipe is also diverted to air bladder 102 through hose 103. As air bladder 102 is continuously inflated, the buoyancy increases, causing the lifting seat 6 to rise slowly. When the lifting seat 6 needs to descend, the air control component 11 plays a role in controlling the air bladder 102 to deflate. Under the action of gravity, the lifting seat 6 falls smoothly back down. In this way, part of the pressure of the air supply equipment is cleverly used to achieve intermittent lifting and lowering of the lifting seat 6. During the lifting process of the lifting seat 6, the inclined surface at the lower part of the guide plate 81 becomes a key guiding component. It can accurately guide the bubbles to the guide hole, so that the bubbles gather in the guide hole. The violent movement of a large number of bubbles in the guide hole forms a strong scouring force, which cleans the surface of the membrane fiber in an all-round and deep way.

[0040] The design has significant benefits. Through the coordinated operation of the aeration component 5 and the suspension mechanism, the cleaning effect of the membrane fibers is greatly improved while ensuring the efficiency of wastewater treatment, effectively delaying membrane fouling and extending the service life of the membrane component. Furthermore, the lifting seat 6 is driven by the residual pressure of the air supply equipment, eliminating the need for an additional power device, reducing the energy consumption of the equipment, achieving energy conservation and emission reduction, and providing good economic and environmental benefits.

[0041] Reference Figure 2 , Figure 3Guide wheels 7 are fixedly installed at the corners of the lifting seat 6, and the guide wheels 7 roll in contact with the outer wall of the fixing frame of the membrane module 4.

[0042] Specifically, the guide wheel 7 is tightly fitted to the outer wall of the fixing frame of the membrane assembly 4, forming a vertical sliding constraint through rolling contact. This design significantly reduces the resistance of the lifting seat 6 during vertical movement through the rolling friction between the guide wheel 7 and the fixing frame, while limiting the horizontal displacement of the lifting seat 6. This ensures that it can slide stably and accurately along the vertical direction of the fixing frame, avoiding deviation or shaking during lifting, thus providing reliable guidance and limiting guarantee for the normal operation of the lifting seat 6.

[0043] Reference Figure 7 , Figure 8 The air control assembly 11 includes an exhaust pipe 111 that is fixedly connected to the diversion pipe 101. A solenoid valve 112 is installed on the exhaust pipe 111, and a solenoid valve 113 is installed on the diversion pipe 101. The solenoid valve 113 is located between the hose 103 and the exhaust pipe 111.

[0044] Specifically, both solenoid valve 112 and solenoid valve 213 are connected to an external control module. The air control component 11 precisely regulates the movement of the lifting seat 6 through the coordinated opening and closing of solenoid valve 112 and solenoid valve 213. When the external control module issues a command to close solenoid valve 112 and open solenoid valve 213, some of the pressurized gas in the air supply pipe is orderly delivered to the two airbags 102 through hose 103 and diverter 101. As the airbags 102 continue to inflate and expand, the buoyancy they generate increases continuously. When the buoyancy is sufficient to overcome the total weight of the lifting seat 6 and the aeration guide 8, the lifting seat 6, with the assistance of the guide wheel 7, rises smoothly to the top position along the fixing frame of the membrane component 4.

[0045] Conversely, when the control module issues a reverse command, causing solenoid valve 112 to open and solenoid valve 113 to close, the air supply passage between hose 103 and diverter pipe 101 is immediately blocked, and the gas in airbag 102 is quickly discharged through exhaust pipe 111. As the gas in airbag 102 decreases, the buoyancy gradually decreases, and the lifting seat 6 slowly descends to the bottom along the fixed frame under its own gravity, completing a complete lifting cycle.

[0046] Reference Figure 2 , Figure 8 The exhaust pipe 111 is a telescopic pipe, and the upper end of the exhaust pipe 111 is connected to the top of the fixing frame of the membrane module 4.

[0047] Specifically, the upper end of the exhaust pipe 111 is securely connected to the top of the fixing frame of the membrane module 4. Utilizing its telescopic characteristics, it can adaptively adjust its length according to the vertical movement of the lifting seat 6. Regardless of whether the lifting seat 6 is in an ascending or descending state, the upper end of the exhaust pipe 111 always remains above the sewage surface in the aeration tank 2. When the air control component 11 controls the airbag 102 to exhaust air, this ingenious design effectively blocks the sewage backflow path, preventing sewage from entering the airbag 102. In this way, the airbag 102 remains dry and clean, preventing buoyancy loss due to sewage intrusion and ensuring a stable output of the lifting power of the lifting seat 6.

[0048] Example 2, refer to Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that an anti-overflow groove 85 is provided on the inclined surface of the guide plate 81, and the anti-overflow groove 85 is connected to the bottom of the guide hole.

[0049] Specifically, when the bubbles generated by the aeration component 5 rise under buoyancy and come into contact with the inclined surface of the guide plate 81, the anti-overflow groove 85 on the inclined surface cooperates with the bottom of the guide hole to form a "bubble guiding barrier," effectively changing the trajectory of the bubbles and preventing them from spreading laterally along the inclined surface and escaping. Under the constraint of the anti-overflow groove 85, bubbles that might otherwise have deviated are precisely guided and all smoothly enter the guide hole. As the bubbles continuously converge in the guide hole, their contact area and impact force with the membrane fiber surface increase significantly, thereby creating a stronger and more efficient scouring effect on the membrane fiber surface.

[0050] During the intermittent lifting process of the lifting seat 6, which is based on a suspension mechanism, the guide holes sequentially sweep across every surface of the membrane fibers. This dynamic cleaning mode ensures that all parts of the membrane fibers are thoroughly cleaned by air bubbles, avoiding any cleaning dead spots. Whether it is the top, bottom, or sides of the membrane fibers, the continuous action of the air bubbles effectively removes attached sludge and other contaminants, maintaining the permeability of the membrane fibers.

[0051] The beneficial effects of this design are remarkable. On the one hand, the ingenious combination of the anti-overflow groove 85 and the guide hole significantly improves the utilization rate of air bubbles, enhances the cleaning efficiency and quality of the membrane fiber surface, helps to delay membrane fouling, and extends the service life of the membrane module. On the other hand, the lifting seat 6 drives the circulating flushing of the guide hole, achieving full coverage cleaning of the membrane fiber surface, effectively ensuring the stable operation of the wastewater treatment equipment and reducing the frequency of equipment downtime and maintenance due to membrane fouling.

[0052] Reference Figure 6 The middle part of the guide hole is cylindrical, and the two ends are frustum-shaped. The inner wall of the middle part of the guide hole is provided with multiple spiral grooves 84 at equal intervals in an annular shape.

[0053] Specifically, when the lifting seat 6 drives the guide plate 81 to rise or fall, the frustum-shaped design at both ends of the guide hole acts like a highly efficient "sewage collection funnel," effectively guiding surrounding sewage to converge in the center of the guide hole, significantly increasing the amount of sewage entering the guide hole. A large amount of sewage, carrying air bubbles, surges into the cylindrical area in the center of the guide hole, forming a strong scouring flow during the flow process, significantly increasing the impact force on the membrane fiber surface. When the sewage and air bubbles pass through the spiral groove 84, they are forced to move along a spiral path due to its structure. This spiral motion mode allows the air bubbles to fully contact the circumferential surface of the membrane fiber in all directions, without dead angles, no longer limited to localized scouring, but rather performing a 360-degree deep cleaning of the membrane fiber surface. Whether it's a protrusion or a depression in the membrane fiber, the attached contaminants can be effectively removed under the scouring of the spirally moving air bubbles. The remaining structure is the same as in Example 1.

[0054] Example 3, referring to Figure 6 This is the third embodiment of the present invention, which differs from the second embodiment in that: an exhaust channel 86 is vertically opened in the middle of the guide plate 81.

[0055] Specifically, some of the bubbles generated by aeration enter the guide holes along the inclined surface, while the rest of the bubbles can continue to float upwards through the exhaust channel 86 and the guide plate 81. During their ascent, these bubbles create a continuous agitation effect in the wastewater surrounding the membrane fibers, effectively breaking the tendency of sludge to deposit on the surface of the membrane fibers and preventing sludge from accumulating and clogging the membrane fiber pores.

[0056] As the lifting seat 6 moves the guide plate 81 up and down, the water flow disturbance caused by the air bubbles passing through the exhaust channel 86 works in conjunction with the scouring effect of the air bubbles in the guide holes. The rising or falling guide plate 81 utilizes dynamic water flow to further enhance the cleaning effect on the membrane fiber surface, ensuring that pollutants such as sludge attached to the membrane fiber can be fully removed, thereby maintaining the permeability of the membrane fiber and the wastewater treatment efficiency.

[0057] Reference Figure 6 Two flow channels 87 are symmetrically opened at the lower part of the flow guide plate 81. The flow channels 87 have a bent structure, and the two ends of the flow channels 87 are connected to the inclined surface and the exhaust channel 86 respectively. A diamond-shaped rod 9 is fixedly connected inside the exhaust channel 86.

[0058] Specifically, when the guide plate 81 moves up or down with the lifting seat 6, the flow state of the sewage in the exhaust channel 86 is changed due to the presence of the rhomboid rod 9. The rhomboid rod 9 breaks the normal flow trajectory of the sewage, causing it to divert. Some sewage follows the guide path formed by the rhomboid rod 9 and enters the bent diversion channel 87 connected to the exhaust channel 86. When the sewage flows in the diversion channel 87, it changes its flow direction with the help of its special bent structure and is finally discharged from one side of the slope.

[0059] The discharged wastewater forms a directional water flow on the inclined surface, propelling air bubbles to move rapidly along the guide holes. Through the synergistic effect of the guide channel 87, the diamond-shaped rod 9, and the inclined surface, the lateral escape of air bubbles on the inclined surface is effectively suppressed, ensuring that air bubbles can quickly and efficiently enter the guide holes and fully exert their flushing and cleaning effect on the membrane fiber surface.

[0060] The flow channel 87 employs a unique V-shaped structure design, creating a dedicated, smooth channel for water flow. Due to water's excellent fluidity and filling capacity, it can freely move within the flow channel 87, while air bubbles, being less dense than water, maintain an upward buoyancy tendency and struggle to enter the channel. During the ascent or descent of the guide plate 81, the flowing water within the channel guides the movement of surrounding air bubbles, precisely directing them towards the guide holes. This effectively prevents bubbles from escaping from the inclined surface of the guide plate 81, significantly improving the efficiency of bubble scouring of the membrane fiber surface. The remaining structure is the same as in Example 2.

[0061] Based on embodiments 1-3, the working principle of this invention is as follows: Wastewater is first degraded by microorganisms in the aerobic reaction tank 1, and then flows into the aeration tank 2. The membrane module 4 is connected to a suction pump, and the membrane fibers generate suction to draw clean water into the clear water tank 3. At the same time, the bubbles generated by the aeration module 5 initially wash the sludge on the surface of the membrane fibers during their ascent, and part of the gas from the air supply pipe inflates the air bag 102 through the hose 103. When the buoyancy of the air bag 102 overcomes the gravity of the lifting seat 6 and the aeration guide 8, it drives the lifting seat 6 to rise. The air control component 11 controls the air bag 102 to release air, and the lifting seat 6 descends under the action of gravity, realizing intermittent lifting and lowering. During the lifting and lowering process, the lower inclined surface of the guide plate 81 and the overflow groove 85 guide the bubbles into the guide hole. The special shape of the guide hole collects wastewater and bubbles, and the spiral groove 84 makes the wastewater bubbles spiral, washing the membrane fibers in all directions. The exhaust channel 86, the diversion channel 87, the diamond rod 9 and other structures further optimize the bubble movement path, prevent bubble escape, enhance the flushing effect, ensure the cleanliness of the membrane fibers, and maintain the stable and efficient operation of the sewage treatment equipment.

[0062] Example 4, refer to Figures 1-8 The fourth embodiment of the present invention provides an integrated wastewater treatment process, comprising the following steps:

[0063] S1. Wastewater enters aerobic reaction tank 1. The organic matter in the wastewater is degraded by microorganisms in activated sludge. The microorganisms use the organic matter to grow and reproduce, forming a mixed liquor.

[0064] S2. The degraded wastewater enters the aeration tank 2. The suction pump creates negative pressure inside the membrane fibers of the membrane module 4. After entering the membrane fiber pore wall, the clean water flows to the clean water tank 3 through the water pipe. The sludge is intercepted in the aeration tank 2.

[0065] S3, the aeration component 5 generates aeration to wash the sludge on the surface of the membrane fibers. At the same time, the air control component 11 intermittently controls the inflation and deflation of the air bag 102. When the air bag 102 is inflated and deflated, it drives the lifting seat 6 to rise and fall synchronously. The inclined surface of the guide plate 81 guides the air bubbles into the guide hole. The air bubbles effectively contact the surface of the membrane fibers under the limit of the guide hole, effectively washing the surface of the membrane fibers.

[0066] S4. The suction pump draws out the clean water from the clean water tank 3 as the final effluent.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it.
