Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a micro-power sewage treatment device based on an integrated module. Background Art

[0002] Urban and rural water supply and drainage mainly include two aspects: water supply and drainage. Sewage treatment plays a key role in this. At present, the treatment of domestic sewage generated in urban and rural areas mainly includes physical treatment such as sedimentation, filtration, biological treatment, the use of microorganisms to decompose organic matter, etc., as well as chemical treatment and disinfection. Through these steps, pollutants in sewage are removed, and the treated water reaches certain standards before being discharged or recycled.

[0003] However, the existing technology generally maintains a uniform processing speed when treating sewage. Once the rainy season comes, the water intake continues to increase, which easily causes the sewage treatment working pressure to increase. When the flow rate is too large, it can easily cause the sewage treatment equipment to overflow, which not only affects the normal operation of the device, but also causes environmental pollution.

The pulsed air lift sludge discharge device 103 is connected to a sludge return pipe 104. The main body shell 100 is also provided with an aeration air pump 105.

In addition, a group of filter screens are also provided inside the first floating frame 201. The side wall of the sedimentation tank 600 is provided with a drain outlet 601, and the side wall of the sedimentation tank 600 is movably connected with a filter screen.

It should be noted that the nitrification liquid reflux is also guided by an air stripping device. Compared with traditional electric pump technology, the use of an air stripping device can save energy consumption and improve system stability and durability.

[0045] It should be noted that the Electric Control Center 101 uses clean energy such as wind power and solar energy to supply power to the power system. Compared with the same type of integrated modules, it is more energy-saving and environmentally friendly, and continuously promotes the synergistic efficiency of pollution reduction and carbon reduction, and promotes the comprehensive green transformation and development of the enterprise.

The surface of the turntable 503 is provided with multiple groups of aeration holes 510 that cooperate with the movable blocks 512.

[0047] It should be noted that the air inlet pipe 106 is designed at an inclined angle so that the air inlet pipe 106 can blow air in the direction of the movable block 512. While acting on the movable block 512, it can keep pushing the movable block 512 along a fixed direction, thereby pushing the fixed block 511 and the turntable 503 to rotate.

[0048] Furthermore, the design position of the aeration hole 510 is located between the movable block 512 and the adjacent group of fixed blocks 511, and the setting position is close to the adjacent group of fixed blocks 511, and a one-way valve is set inside the aeration hole 510. When the movable block 512 is reset, the gas between the movable block 512 and the adjacent group of fixed blocks 511 can be fully pumped out as much as possible.

[0049] It should be noted that the surface of the crushing blade group 509 is provided with dense filter holes.

[0050] Reference Figure 5-11 The sludge mechanism includes a sludge disc 502 arranged inside the main shell 100, and the sludge disc 502 is located above the aerobic tank 500. The center of the sludge disc 502 is rotatably connected to a driven shaft 522. The driven shaft 522 and the rotating shaft 508 are coaxially designed. The top of the rotating shaft 508 is sleeved with a hexagonal shaft 521, and the top of the hexagonal shaft 521 is sleeved with the driven shaft 522. The outer wall of the hexagonal shaft 521 is connected to a movable block 520. A second floating frame 532 is provided inside the aerobic tank 500, and a filter is provided on the inner side of the second floating frame 532. A connecting bracket 533 that cooperates with the movable block 520 is also provided on the inner side of the second floating frame 532. The outer wall of the driven shaft 522 is connected to a mixing blade 531. The top of the sludge disc 502 is provided with a sealed chamber 2 528 and a sealed chamber 1 52 7. The sealed chamber 1 527 is communicated with the interior of the sludge pan 502. The sludge return pipe 104 is provided with a mud guide pipe 525 communicated with the sealed chamber 1 527. The interior of the sealed chamber 1 527 is slidably connected with a slider 2 526 that cooperates with the mud guide pipe 525. The interior of the sealed chamber 2 528 is slidably connected with a slider 1 524. The outer wall of the driven shaft 522 is installed with a convex shaft 523 that cooperates with the slider 2 526 and the slider 1 524. The interior of the sludge pan 502 is provided with a group of drainage pipes 530 extending to the interior of the anoxic tank 300. The sealed chamber 2 528 is provided with a group of drainage pipes 529 extending to the interior of the aerobic tank 500. The drainage pipe 529 is provided with a one-way valve for sucking liquid. The sealed chamber 2 528 is provided with a group of one-way valves for pumping liquid toward the interior of the sludge pan 502.

[0051] Furthermore, a through groove that cooperates with the mud guide pipe 525 is provided inside the slider 2 526, and a spring is provided between the slider 2 526 and the sealing chamber 1 527. The side wall of the sealing chamber 1 527 is also provided with a one-way air inlet and outlet valve connected to the outside, and the intake speed of the one-way air inlet valve in the one-way air inlet and outlet valve is less than the exhaust speed of the one-way air outlet valve. When the convex shaft 523 pushes the slider 2 526 so that the through groove of the slider 2 526 is connected with the mud guide pipe 525, the sludge inside the sludge return pipe 104 can enter the sludge pan 502 through the mud guide pipe 525 and the slider 2 526. The slow intake speed of the one-way air inlet valve can reduce the reset speed of the slider 2 526. When the convex shaft 523 pushes the slider 2 526 to move until the convex shaft 523 rotates to push the slider 2 526 for the next time, the displacement of the slider 2 526 is small, which can maintain the connection between the mud guide pipe 525 and the sludge pan 502.

The inner side wall of the sludge pan 502 is provided with an inner gear ring 537 that matches the driving gear 536. A sealing ring 538 is provided between the driving gear 536 and the mixing blade 531. The sealing ring 538 is rotatably connected to the sludge pan 502. It should be noted that the sealing ring 538 is rotatably connected to the mixing shaft 534, and the sealing ring 538 can maintain sealing protection for the inner gear ring 537 during rotation.

[0053] Furthermore, a spherical cavity 204 is provided on the side wall of the regulating tank 200, and a drive shaft 205 is rotatably connected to the inside of the spherical cavity 204. Both ends of the drive shaft 205 extending to the outside of the spherical cavity 204 are provided with stirring blade groups 207. The side wall of the drive shaft 205 is provided with a drive blade group 206 that cooperates with the inside of the spherical cavity 204. One end of the spherical cavity 204 is connected to the connecting pipe 102, and the other end of the spherical cavity 204 is provided with a spherical net 208.

[0054] The working process of the micro-power sewage treatment equipment based on the integrated module is as follows:

[0055] During normal sewage treatment, sewage enters from the water inlet of the regulating tank 200. After being regulated inside the regulating tank 200, the sewage inside the regulating tank 200 is guided into the anoxic tank 300 under the action of the air stripping device connected to the connecting pipe 102. It should be noted that when the sewage passes through the spherical net 208, the spherical cavity 204, and the first movable plate 202 into the connecting pipe 102, the spherical design of the spherical net 208 can filter large particles of suspended solids while increasing the filtration area to avoid blockage caused by local accumulation. Moreover, when the water flows through the driving blade group 206, it can drive the driving shaft 205 to rotate, and further drive the upper and lower stirring blade groups 207 to rotate synchronously, mixing and disturbing the sewage to be treated entering the connecting pipe 102, so that sewage of different components can be better mixed before entering the anoxic tank 300, which is conducive to the stability and efficiency of the subsequent treatment process, and can reduce the deposition of solid matter at the entrance and reduce the risk of blockage.

[0056] After entering the anoxic tank 300, the sewage further enters the anaerobic tank 400, passes through the baffle 401 to block the turbulence, and enters the aerobic tank 500. During this process, the sewage is treated by anoxic and anaerobic treatment methods, and the action of nitrifying bacteria is used to hydrolyze and acidify organic matter, remove organic matter in the wastewater, and improve the biodegradability of the sewage.

[0057] After the sewage enters the aerobic tank 500 and undergoes biochemical degradation of organic matter by aerobic bacteria, it enters the sedimentation tank 600. The sludge settles under the action of gravity in the chute at the bottom of the sedimentation tank 600. It is collected by the pulsed air lift sludge discharge device 103 and then lifted through the sludge return pipe 104 to return to the anoxic tank 300 for sludge return treatment. The concentration of microorganisms in the system is maintained to ensure the stability of the sewage treatment effect, which is conducive to the domestication and proliferation of microorganisms and enables the microorganisms to better adapt to the characteristics of sewage. The treated water is discharged through the drain outlet 601 to complete the sewage purification process.

[0058] When the sewage is biochemically treated in the aerobic tank 500, the aeration pump 105 continuously pressurizes and ventilates the inside of the aeration plate 501 through the air inlet pipe 106. When the pressure inside the aeration plate 501 increases, the movable block 512 can be pushed to move toward the fixed block 511, and the spring between the fixed block 511 and the movable block 512 is compressed, so that the gas is compressed and stored inside the aeration plate 501. At the same time, the air is continuously pumped at an inclined angle through the air inlet pipe 106, which can push the movable block 512 to further drive the fixed block 511 and the turntable 503 to rotate. When the turntable 503 rotates, when the turntable 503 rotates until the aeration hole 510 is free from the obstruction of the fixed block 511, the movable block 512 will be reset by the spring connected to the fixed block 511. The stored gas is continuously discharged through the aeration holes 510. The rotation of the turntable 503 also drives the sleeve shaft 504 and the first bevel gear 505 to rotate. The first bevel gear 505 drives the second bevel gear 506 to rotate synchronously in the opposite direction through the transmission gear 507, thereby driving the crushing blade group 509 on the rotating shaft 508 to rotate in the opposite direction to the turntable 503. The filter hole design on the surface of the crushing blade group 509 can not only evenly disperse the force, increase the fluidity of the sewage inside the aerobic tank 500, and generate more vortexes during stirring, but also break and refine the bubbles discharged from the aeration holes 510, increase the gas contact area, improve the aeration efficiency, make the sewage, sludge and oxygen in the aerobic tank 500 more fully mixed, promote material exchange and reaction, and improve treatment efficiency.

[0059] When the water flow increases in the rainy season, resulting in an increase in the water flow entering the regulating tank 200, the first floating frame 201 floats up due to the increase in the internal liquid level of the regulating tank 200 until it contacts the first movable plate 202 and pushes the first movable plate 202 to move up. When the first movable plate 202 moves up, it can reduce the obstruction to the entrance of the connecting pipe 102 and increase the flow entering the connecting pipe 102. When the flow entering the anoxic tank 300 through the connecting pipe 102 increases, the liquid levels of the subsequent aerobic tank 500 and the sedimentation tank 600 will also rise. When the liquid level of the sedimentation tank 600 rises, the second movable plate 602 will be pushed up by the floating of the third floating frame 603, reducing the obstruction to the drain outlet 601 and increasing the drainage volume, thereby realizing self-regulation of entry and discharge when the inlet flow increases. The flow rate is increased to reduce the occurrence of overflow. When the flow rate continues to increase until the first movable plate 202 moves up to push the trigger switch 203, the flow rate and liquid level approach the threshold value. At this time, the electrical connection of the gas stripping device connected to the trigger switch 203, the electric control center 101 and the connecting pipe 102 is increased, so that the power of the gas stripping device of the connecting pipe 102 is increased, the water inlet of the anoxic tank 300 is increased, and the liquid accumulation in the regulating tank 200 is avoided. At the same time, the liquid levels of the subsequent aerobic tank 500 and the sedimentation tank 600 also continue to rise. After the second movable plate 602 rises to the highest point, it can discharge the liquid through the drain port 601 with the maximum flow cross section to avoid liquid accumulation. When the second floating frame 532 also pushes the movable block 520 to move up when the liquid level rises to the highest point, the hexagonal shaft 521 is connected to the driven shaft 522 in transmission. The rotating shaft 508 drives the driven shaft 522 to rotate synchronously through the hexagonal shaft 521. When the driven shaft 522 rotates, it can drive the convex shaft 523 to rotate, and circulate to push the slider 2 526 and the slider 1 524. After the slider 2 526 is pushed, it can move so that the sludge plate 502 is connected with the mud guide pipe 525 and the sludge return pipe 104 through the groove inside the slider 2 526, and the sludge inside the sludge return pipe 104 is diverted to the inside of the sludge plate 502. When the convex shaft 523 circulates and pushes the slider 1 524, a group of piston pump mechanisms can be formed, which continuously sucks the liquid inside the aerobic tank 500 into the sealed chamber 2 528 through the liquid guide pipe 529, and then pumps it into the sludge plate 502 to mix with the sludge entering the sludge plate 502. The rotation of the driven shaft 522 can The mixing blades 531 are driven to rotate synchronously, and the cooperation of the driving gear 536 and the inner gear ring 537 is used to drive the mixing shaft 534 and the secondary blades 535 to rotate synchronously, so as to further refine and crush the sludge inside the sludge disc 502 and continuously mix and stir it with the liquid. Then, when the liquid level rises, the sludge is returned to the anoxic tank 300 in the form of an aqueous solution through the drain pipe 530 opened on the side wall of the sludge disc 502 near the top, so that the sludge can be quickly and evenly distributed in the sewage, the reaction speed is improved, and the treatment effect is guaranteed. The switching of the sludge return mode in the sewage treatment process is realized. In the normal mode, the sludge is returned to the anoxic tank 300 in the form of a solid state, which helps to maintain sufficient biomass in the biological treatment system and ensure the treatment efficiency.During the rainy season, rising liquid levels drive the hexagonal shaft 521 upward, connecting the rotating shaft 508 and the driven shaft 522. The rotation of the cam 523 connects the sludge return pipe 104 to the sludge pan 502, diverting the sludge. Simultaneously, the piston pump mechanism of the cam 523 and driven shaft 522 continuously pumps liquid into the anoxic tank 300, where it is fully refined and mixed with the mixing blades 531. The sludge and liquid are then returned to the anoxic tank 300, increasing reaction speed and coping with the high flow rate during the rainy season.

[0060] It should be noted that solid and liquid sludge return methods each have their own advantages. By switching automatically, high-quality sewage treatment can be achieved in normal seasons, and the treatment environment is more stable. In the rainy season, when the flow rate increases significantly, the treatment cycle becomes shorter, and liquid return can be used to increase the contact between sewage and sludge mixture and increase the reaction speed, thereby ensuring the quality of sewage treatment while reducing the treatment time.

[0061] It should be noted that the air stripping device of the connecting pipe 102 matches the maximum drainage speed of the drain outlet 601, and will not increase the flow rate introduced into the anoxic tank 300 to a speed exceeding the drainage speed of the drain outlet 601, thereby avoiding liquid accumulation.

Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
