To achieve the environmental protection treatment of sewage and improve the sewage treatment efficiency.

[0005] Therefore, in view of the above problems, an environmentally friendly sewage treatment device based on microbial reaction is proposed to solve the above problems. Summary of the Invention

The primary treatment component includes a bracket, the tank body is connected to symmetric upper guiding round rods, the symmetric upper guiding round rods respectively pass through the bracket, the bracket is connected to the impeller shaft by bearings, the bracket is connected to a stepped round pipe, the central axis of the impeller shaft is arranged inside the stepped round pipe, the upper end blades of the impeller shaft are located inside the drain pipe, the impeller shaft is connected to a power bevel gear, the stepped round pipe is connected to the gear shafts of a group of driven bevel gears by bearings, each driven bevel gear meshes with the power bevel gear respectively, each driven bevel gear is respectively connected to an inner turntable, inner round blocks are respectively connected to the edges of each inner turntable, the vertical rods of a group of I-shaped plates respectively pass through the bracket, each I-shaped plate is provided with a horizontal groove, and each inner round block is respectively arranged in the corresponding horizontal groove. The bracket is connected to a group of air cylinders, each I-shaped plate is connected to a piston, the piston rods of each piston respectively pass through the top plates of the corresponding air cylinders, each piston respectively matches the corresponding air cylinder, and each air cylinder is fixedly communicated with an exhaust pipe and an intake pipe. By utilizing the impact of the water flow on the impeller shaft, the power bevel gear is rotated, and then the I-shaped plate drives the piston to move, so as to realize the pressurized ejection of oxygen-rich air. The exhaust pipe is located at the lower position of the storage tank, so that the air has a long movement distance in the water, which is convenient for the sewage to fully contact with the air, making the tank body in an oxygen-rich state. The reciprocating movement of the I-shaped plate contacts the falling sewage, which plays a role in hindering the flow of the sewage. The water spreads on the plane of the bracket and then flows into the storage tank, increasing the residence time and the contact area with the air. The oxygen-rich sewage contacts the MBR membrane on the partition plate of the water wheel, which is convenient for treatment.

[0009] As an optimization, the bracket is connected to two groups of symmetric middle vertical rods, each of the middle vertical rods is rotatably connected to a stirring plate, each of the stirring plates is connected to a symmetric straight groove rod, the bracket is connected to symmetric return blocks, symmetric middle guide rods respectively pass through the corresponding return blocks, the symmetric middle guide rods are respectively connected to round head rods, one end of each of the lower springs is connected to each of the round head rods, the symmetric lower springs respectively surround the corresponding middle guide rods, the symmetric lower springs are respectively connected to the corresponding return blocks, the lower end of the impeller shaft is connected to an eccentric circular block, the symmetric round head rods respectively contact the eccentric circular block, each of the round head rods is connected to a T shaft, and the circular shaft ends of the symmetric T shafts are respectively arranged in the grooves of the corresponding straight groove rods.

[0010] As an optimization, it further includes a transmission assembly. The transmission assembly includes symmetric transmission gears. The symmetric transmission gears are respectively connected to the inverted T plates by bearings. Each of the transmission gears meshes with a toothed ring. Each of the toothed rings is connected to the water wheel. The symmetric inverted T plates are respectively provided with outer straight grooves. Each of the outer straight grooves is provided with an outer round rod. Each of the outer round rods is connected to the corresponding inverted T plate. Each of the transmission gears is connected to a middle turntable. One end of each of the power connecting rods is rotatably connected to the edge of each of the middle turntables. The bracket is connected to symmetric sliders. The symmetric sliders are respectively arranged in the corresponding outer straight grooves.

Moreover, after the water wheel stops rotating, the primary treatment assembly is at the lowest end of its stroke and at the central position of the storage tank, facilitating the treatment of sewage.

[0011] As an optimization, the two ends of the main shaft are respectively connected to outer turntables, and the edges of the symmetric outer turntables are respectively connected to outer round blocks.

The MBR membrane plate is in an oxygen-rich box and moves in the height direction. When the block is in the sink, the sink is sealed and the MBR membrane plate is fully in contact with the sewage. Compared with the existing method of directly placing the MBR membrane plate on the lower side of the drain pipe, the treatment effect is better. After a period of contact with the sewage, the block is separated from the sink to achieve the discharge of oxygen-rich sewage in the box. In addition, due to the addition of oxygen-rich air, its pressure is relatively larger than that of the aerobic tank, and the sewage is pressurized and sprayed out, which intensifies the movement of sewage in the aerobic tank and impacts the active mud layer containing aerobic bacteria, so that the microbial community migrates accordingly, which can promote the mutual communication between the microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, and produce more excellent offspring to enhance the ability to decompose pollutants in sewage.

[0013] As an optimization, it also includes a pool oxygenation component, which includes a group of main pipes, each of which is provided with a group of air outlets on the upper part, each of which is fixedly connected to an air intake vertical pipe, and each of which is connected to a guide cross bar at both ends, and a symmetrical guide base plate is connected in the aerobic pool, each of which passes through the corresponding guide base plate, and each of which is connected to a mounting long plate on one side, and the mounting long plate is connected to a symmetrical lower vertical rod, and the symmetrical outer circular blocks are respectively connected to one end of the power inner rod, and the other end of the symmetrical power inner rod is respectively connected to the corresponding lower vertical rod.

By changing the oxygen discharge position, the microbial community migrates accordingly, which can promote mutual communication between various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, and produce more excellent offspring to enhance the ability to decompose pollutants in sewage.

[0014] As an optimization, it further includes a cleaning component. The cleaning component includes a set of counterweight blocks.

Each upper spring respectively sleevs the corresponding inner round rod. One end of each counterweight block is respectively rotatably connected to a symmetric inner connecting rod. The other end of each inner connecting rod is respectively rotatably connected to an inner mounting block. Each inner mounting block is respectively connected to a brush plate. Each guiding thin rod respectively passes through the corresponding brush plate. By using the gravity of the counterweight blocks, the elastic force of the upper springs, and the centrifugal force generated when the water wheel rotates, the brush plate is enabled to move along the surface of the MBR membrane on the partition of the water wheel to clean the MBR membrane on the partition of the water wheel.

[0015] As an optimization, the main shaft is connected to a driven gear, the box body is connected to a motor, the output shaft of the motor is connected to a driving gear, and the driving gear meshes with the driven gear. By adopting gear meshing and driving by the motor, the rotation of the water wheel is realized.

[0016] The effects provided in the invention content are only the effects of the embodiments, rather than all the effects of the invention. The above technical solutions have the following advantages or beneficial effects:

[0017] 1. By storing the sewage in the box body for a period of time to make the sewage contact with the MBR membrane for a period of time, the first treatment of the sewage is realized. An aerobic sludge layer containing aerobic bacteria colonies is placed in the aerobic tank to decompose the pollutants in the sewage, realizing the second treatment of the sewage, achieving the secondary microbial treatment of the sewage, organically combining microbial degradation and biofilm technology, and realizing the environmental protection treatment of the sewage.

[0018] 2. When the water wheel of the device rotates, the primary treatment component moves as a whole to avoid the contact between the primary treatment component and the partition of the water wheel and cause damage to the equipment. Moreover, after the water wheel stops rotating, the primary treatment component is at the bottom of its stroke and in the center of the storage tank. The exhaust pipe is located at the lower part of the storage tank, so that the air moves a large distance in the water, which is convenient for the sewage to fully contact with the air, so that the box is in an oxygen-rich state. The I-shaped plate reciprocates to contact the falling sewage, which hinders the flow of sewage. The water spreads on the support plane and then flows into the storage tank, increasing the air retention time and the contact area with the air. The oxygen-rich sewage contacts the MBR membrane on the partition of the water wheel, which is convenient for treatment. When the block is used to treat the lower sink, the lower sink is sealed, the MBR membrane plate is fully contacted with the sewage, the block is separated from the lower sink, and the oxygen-rich sewage in the box is discharged. Moreover, due to the addition of oxygen-rich air, its pressure is relatively large compared to the aerobic pool, so that the sewage is pressurized and ejected, so that the movement of the sewage in the aerobic pool is intensified, and the active mud layer containing aerobic bacteria is impacted.

[0019] 3. When the water wheel of the device rotates, the position of the air outlet changes, and oxygen-rich air is discharged. The change in the oxygen discharge position and the impact of the oxygen-rich sewage discharge in the box cause the microbial community to migrate, which can promote the mutual communication between the various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, produce more excellent offspring, and enhance the ability to decompose pollutants in sewage.

The symmetric guiding vertical circular rods 84 respectively pass through the corresponding outer guiding blocks 33. The symmetric outer circular blocks 49 are respectively rotatably connected to one ends of power outer rods 41. The other ends of the symmetric power outer rods 41 are respectively rotatably connected to the mounting cross plate 81. The MBR membrane plate 83 is located in the oxygen-rich box body 32 and moves along the height direction. When the blocking blocks 82 are in the water discharge grooves 38, the water discharge grooves 38 are sealed, enabling the MBR membrane plate 83 to be in full contact with the sewage. Compared with the existing method of directly placing the MBR membrane plate 83 under the drain pipe 31, the treatment effect is better. After being in contact with the sewage for a period of time, the blocking blocks 82 are separated from the water discharge grooves 38, enabling the discharge of the oxygen-rich sewage in the box body 32. And because oxygen-rich air is added, its pressure is relatively higher than that of the aerobic tank 1, enabling the pressurized ejection of the sewage, intensifying the movement of the sewage in the aerobic tank 1, impacting the aerobic bacteria-containing activated sludge layer, and causing the microbial community to migrate accordingly, which can promote the mutual communication between various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, producing more excellent offspring to enhance the decomposition ability of pollutants in the sewage.

[0055] The working process of this embodiment is as follows:

[0056] When the main shaft 46 rotates, it drives the outer turntables 48 to rotate. The outer turntables 48 drive the outer circular blocks 49 to swing. The outer circular blocks 49 drive the power outer rods 41 to swing. The power outer rods 41 drive the mounting cross plate 81 to reciprocate. The mounting cross plate 81 drives the guiding vertical circular rods 84 to reciprocate along the outer guiding blocks 33. The mounting cross plate 81 drives the blocking blocks 82 to reciprocate, enabling them to enter and separate from the water discharge grooves 38.

And the blocking blocks 82 stay in the water discharge grooves 38 for a long time, and the water wheels 47 rotate to stir the wastewater, enabling the oxygen-rich wastewater to be in full contact with the MBR membrane plates 83. The blocking blocks 82 stay away from the water discharge grooves 38 for a short time, enabling the wastewater to be discharged in a short time.

The pond aeration component 2 includes a set of main pipes 25. A set of air outlet holes 26 are respectively arranged on the upper parts of each of the main pipes 25. Each of the main pipes 25 is fixedly connected and communicated with an intake vertical pipe 24. The two ends of each of the main pipes 25 are respectively connected to a guiding cross bar 23. Symmetric guiding bottom plates 11 are connected inside the aerobic pond 1. Each of the guiding cross bars 23 passes through the corresponding guiding bottom plate 11. On one side, each of the guiding cross bars 23 is respectively connected to an installation long plate 22. The installation long plate 22 is connected to symmetric lower vertical rods 21. The symmetric outer round blocks 49 are respectively rotatably connected to one ends of the power inner rods 42. The other ends of the symmetric power inner rods 42 are respectively rotatably connected to the corresponding lower vertical rods 21. The positions of the air outlet holes 26 change, and oxygen-rich air is discharged. By changing the oxygen discharge position, the microbial communities move accordingly, which can promote the mutual communication between various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, and produce more excellent offspring to improve the decomposition ability of pollutants in sewage.

[0058] The working process of this example is as follows:

[0059] Connect the oxygen-rich air source with a ventilation pipe, and make the ventilation pipe be respectively connected to the intake vertical pipes 24.

[0060] The outer round block 49 drives the power inner rod 42 to swing. The power inner rod 42 drives the lower vertical rod 21 and the installation long plate 22 to move. The installation long plate 22 drives the guiding cross bar 23 to move along the guiding bottom plate 11. The guiding cross bar 23 drives the main pipe 25 and the intake vertical pipe 24 to reciprocate. The positions of the air outlet holes 26 change, and oxygen-rich air is discharged. By changing the oxygen discharge position, the microbial communities move accordingly, which can promote the mutual communication between various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, and produce more excellent offspring to improve the decomposition ability of pollutants in sewage.

[0061] Embodiment 5: This embodiment is further elaborated on the basis of Embodiment 1 or 2 or 3 or 4, and further includes a cleaning component 6. The cleaning component 6 includes a set of counterweight blocks 65. On both sides of each partition of the water wheel 47, symmetric guiding thin rods 410 are respectively connected. The water wheel 47 is provided with a set of symmetric inner straight grooves 411 evenly distributed. In each of the inner straight grooves 411, an inner round rod 412 is respectively arranged. Each of the inner round rods 412 is respectively connected to the water wheel 47. In each of the inner straight grooves 411, the corresponding counterweight blocks 65 are respectively arranged. Each of the inner round rods 412 respectively passes through the corresponding counterweight blocks 65. Each of the counterweight blocks 65 is respectively connected to the water wheel 47 through an upper spring 64. Each of the upper springs 64 respectively sleeves the corresponding inner round rod 412. One end of each of the counterweight blocks 65 is respectively rotatably connected to a symmetric inner connecting rod 63. The other end of each of the inner connecting rods 63 is respectively rotatably connected to an inner mounting block 61. Each of the inner mounting blocks 61 is respectively connected to a brush plate 62. Each of the guiding thin rods 410 respectively passes through the corresponding brush plate 62. By using the gravity of the counterweight blocks 65, the elastic force of the upper springs 64, and the centrifugal force generated when the water wheel 47 rotates, the brush plate 62 is enabled to move along the surface of the MBR membrane on the partition of the water wheel 47 to clean the MBR membrane on the partition of the water wheel 47.

[0062] The working process of this embodiment is as follows:

[0063] Due to the large mass of the counterweight blocks 65, as the water wheel 47 rotates, the counterweight blocks 65 move along the inner round rods 412 in the inner straight grooves 411. The counterweight blocks 65 drive the upper springs 64 to move. The counterweight blocks 65 drive the inner connecting rods 63 to swing. The inner connecting rods 63 drive the inner mounting blocks 61 to move. The inner mounting blocks 61 drive the brush plates 62 to move along the guiding thin rods 410, and the brush plates 62 clean the MBR membrane on the partition of the water wheel 47.

[0064] This device stores the sewage in the box body 32 for a period of time to enable the sewage to contact the MBR membrane for a period of time, thereby realizing the first treatment of the sewage. In the aerobic tank 1, an active sludge layer containing aerobic bacteria groups is placed to decompose the pollutants in the sewage, realizing the second treatment of the sewage, realizing the secondary microbial treatment of the sewage, organically combining microbial degradation and biofilm technology, and realizing the environmental protection treatment of the sewage.

[0065] When the water wheel 47 of the device rotates, the primary treatment component 5 moves as a whole, avoiding damage to the equipment caused by the contact between the primary treatment component 5 and the partition of the water wheel 47. Moreover, after the water wheel 47 stops rotating, the primary treatment component 5 is at the lowest end of its travel, at the center of the storage tank. The exhaust pipe 516 is located at the lower part of the storage tank, so that the air moves a large distance in the water, which is convenient for the sewage to fully contact the air, so that the box body 32 is in an oxygen-rich state, and the I-shaped plate 520 reciprocates to contact the falling sewage, which hinders the flow of sewage. The water expands on the plane of the bracket 56 and then flows into the storage tank, increasing the air retention time and the contact area with the air. The oxygen-rich sewage contacts the MBR membrane on the partition of the water wheel 47, which is convenient for treatment. When the block 82 is processing in the lower water tank 38, the lower water tank 38 is sealed, and the MBR membrane 83 is fully in contact with the sewage. The block 82 is separated from the lower water tank 38, and the oxygen-rich sewage in the box body 32 is discharged. Moreover, due to the addition of oxygen-rich air, its pressure is relatively larger than that of the aerobic tank 1, and the sewage is pressurized and ejected, which intensifies the movement of the sewage in the aerobic tank 1 and impacts the active mud layer containing aerobic bacteria.

[0066] When the water wheel 47 of the device rotates, the position of the air outlet 26 changes, and oxygen-rich air is discharged. The change in the oxygen discharge position and the impact of the oxygen-rich sewage in the box 32 when it is discharged cause the microbial community to migrate accordingly, which can promote the mutual communication between the various microbial communities, so as to promote the reproduction of protozoa and micro-animals in different microbial communities, produce more excellent offspring, and enhance the ability to decompose pollutants in sewage.

[0067] Although the above describes the specific implementation mode of the invention in conjunction with the drawings, it is not intended to limit the scope of protection of the invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
