Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a complete set of equipment for improving the quality and efficiency of domestic sewage. Background Art

[0002] In recent years, with the continuous development and innovation of sewage treatment technology, integrated technology has gradually become a research hotspot in the field of sewage treatment. The complete set of equipment for improving the quality and efficiency of domestic sewage is to integrate multiple sewage treatment units, such as pretreatment, biological treatment, deep treatment, etc., into one device or a group of equipment. Through optimized design and reasonable layout, the high efficiency of sewage treatment is achieved. With the increasing shortage of water resources, the resource utilization of sewage has become a development trend in the sewage treatment industry. While improving the sewage treatment effect, the complete set of equipment for improving the quality and efficiency of domestic sewage also pays attention to the recycling of water resources. Through deep treatment technology, the treated sewage meets the reuse standards and can be used for greening irrigation, road spraying, landscape water replenishment, etc., realizing the recycling of water resources, improving the utilization efficiency of water resources, and meeting the requirements of sustainable development.

[0003] In the existing technology, due to the presence of many impurities in domestic sewage, it needs to be appropriately integrated and adapted according to the newly added sewage in the regulating tank to ensure that the subsequent biological treatment pressure is small, the treatment efficiency is stable, the water quality is uneven, and the sewage concentration is moderate. At present, there are still the following defects that affect the stable operation of the entire set of equipment:

[0004] 1. The stirring blades in the regulating tank are fixed and cannot be adjusted. Therefore, when new sewage appears, the concentration of the stirred liquid at the bottom and top of the tank is quite different;

[0005] 2. The stirring direction and stirring flow direction in the equalization tank are fixed, and the stirring flow direction and stirring direction cannot be changed according to the concentration adjustment requirements, which causes sewage to easily settle at the bottom and the sewage concentration is high. When heavy rain occurs, the internal sewage discharge pressure will be huge, the microorganisms will not respond in time, and the sewage system will collapse. Summary of the invention

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a complete set of equipment for improving the quality and efficiency of domestic sewage, which can adjust the angle of the stirring blades, change the stirring flow direction and disrupt the bottom sedimentation, so as to solve the problem that when new sewage is added, the stirring flow direction and stirring direction cannot be changed according to the concentration adjustment requirements, resulting in sewage easily settling at the bottom and a high sewage concentration.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] The equipment for improving the quality and efficiency of domestic sewage comprises a sewage treatment integrated tank 1, a water inlet 2 connected to the top of one side of the sewage treatment integrated tank 1, a drain outlet 3 connected to the bottom of the sewage treatment integrated tank 1 away from the water inlet 2, and an inspection cover 4 threadedly connected to the top of the sewage treatment integrated tank 1. The first partition 11, the second partition 12, the third partition 13, the fourth partition 14 and the fifth partition 15 are fixedly installed in the interior of the sewage treatment integrated tank 1 from left to right. The inner wall of the sewage treatment integrated tank 1 is opened on one side close to the first partition 11. A mounting groove 6 is provided, and a limiting frame 61 is fixedly installed at the top center of the inner wall of the mounting groove 6 on the side away from the first partition 11, a driving motor 7 is fixedly installed on the top of one side of the inner wall of the mounting groove 6, and a limiting base 8 is fixedly installed on the front and rear sides of the bottom of the inner wall of the mounting groove 6. A stirring column 9 is rotatably installed between the limiting base 8 and the first partition 11, and a stabilizing frame 91 is detachably installed on the surface of the stirring column 9. A limiting frame 2 62 symmetrically installed on both sides of the limiting frame 61 is fixedly installed on the side of the inner wall of the mounting groove 6 away from the first partition 11.

[0036] See also Figure 2 , Figure 2 It is a schematic diagram of the half-cut three-dimensional structure of the present invention.

[0037] The cavity formed by the side of the first partition 11 away from the second partition 12 and the sewage treatment integrated tank 1 is a regulating tank, an anaerobic tank is formed inside the sewage treatment integrated tank 1 between the first partition 11 and the second partition 12, an anoxic tank is formed inside the sewage treatment integrated tank 1 between the second partition 12 and the third partition 13, an aerobic tank is formed inside the sewage treatment integrated tank 1 between the third partition 13 and the fourth partition 14, a sedimentation tank is formed inside the sewage treatment integrated tank 1 between the fourth partition 14 and the fifth partition 15, and a filtering chamber is formed between the side of the fifth partition 15 away from the fourth partition 14 and the interior of the sewage treatment integrated tank 1.

[0038] The regulating tank regulates the water quality composition and concentration of sewage from different sources or the same sewage source at different times. Mixing high-concentration acidic sewage and alkaline sewage in the regulating tank may neutralize the pH and reduce corrosion to subsequent treatment units. The anaerobic tank uses the metabolism of anaerobic microorganisms to decompose large-molecule organic matter in sewage into small-molecule organic matter, reduce the chemical oxygen demand COD of sewage, and remove some organic pollutants. Under anaerobic conditions, denitrifying bacteria use organic matter in sewage as a carbon source to reduce nitrate nitrogen in the reflux liquid of the aerobic tank to nitrogen gas, thereby removing nitrogen pollutants in sewage and achieving the purpose of denitrification. Under aerobic conditions, aerobic microorganisms completely decompose the organic matter in the sewage into inorganic substances such as carbon dioxide and water, further reducing the COD and BOD of the sewage and removing most of the organic pollutants. The sedimentation tank separates the mud and water of the biologically treated sewage, so that the suspended solid matter in the sewage settles to the bottom of the tank to form sludge, and the supernatant is discharged as the treated effluent, achieving the purpose of solid-liquid separation and improving the effluent quality. The filter tank further removes the fine suspended particles, colloidal substances and some soluble organic matter remaining in the sewage, improves the clarity and water quality stability of the effluent, and makes the effluent meet higher water quality standards to meet the requirements of reuse or discharge.

A worm gear 6495 is fixedly installed at the center of the surface of the seven groups of flip shafts 6496. A placement groove 92 is opened at the top of the stirring column 9 and is located at the center of the seven groups of flip shafts 6496. A stable frame 91 is fixedly installed on both sides of the stirring column 9, and the two ends of the flip shaft 6496 are rotatably matched with the stable frame 91.

[0046] After the driving gear ring 6491 is driven by the gear 2 649, it can drive the gear 3 6492 meshing with it to rotate through the inner ring.

At the same time, the liquid is diverted through the small holes, which reduces the resistance encountered by the stirring blade when pushing the liquid, and can also reduce the power required to drive the drive motor 7.

[0051] Working principle: When new sewage enters the water inlet 2, two sets of stirring columns 9 are required to cooperate to make the sewage concentration in the upper and lower layers of the regulating tank uniform. At this time, the stirring blade 6497 needs to be adjusted to a horizontal state;

[0052] Starting the electromagnetic push rod 621 drives the driving frame 1 622 to move toward the side close to the limiting frame 2 62, and then drives the driving frame 2 623 to move toward the side away from the limiting frame 2 62 through the sliding connecting rod 624, so that the driving frame 2 623 drives the gear 1 64 to mesh with the reduction box 641, and then drives the angle bevel gear 1 642 to rotate through the output end of the reduction box 641, drives the angle bevel gear 2 643 to rotate through the angle bevel gear 1 642, and then drives the angle driving longitudinal rod 644 to rotate through the angle bevel gear 2 643, and the angle driving longitudinal rod 644 drives the angle bevel gear 3 646 fixed thereto to rotate, and the angle bevel gear 3 646 drives the angle bevel gear 4 648 meshed therewith to rotate, and the angle bevel gear 4 648 drives the slave fixed thereto The driving shaft 647 rotates, and the driven shaft 647 can drive the gear 2 649 fixed thereto to rotate, and then drive the driving gear ring 6491 meshing therewith to rotate. After being driven by the gear 2 649, the driving gear ring 6491 can drive the gear 3 6492 meshing therewith to rotate through the inner ring. The rotation of the gear 3 6492 drives the angle driving cross bar 6493 fixed thereto to rotate, and the angle driving cross bar 6493 drives the worm 6494 to rotate. The rotation of the worm wheel 6495 is limited by the placement groove 92, so that it is stably meshed with the worm 6494 and drives the flip shaft 6496 to rotate. Then, the stirring blade 6497 is driven to rotate through the flip shaft 6496 to change the stirring angle, and the stirring blade 6497 is driven to a horizontal state.

[0053] At this time, the stirring column 9 rotates and drives the stirring blade 6497 to rotate, which can contact the sewage over a large area. Although the resistance increases at this time, it helps to quickly stir and merge the bottom sewage and the newly added sewage together, and the holes in cooperation with the through holes 6498 can form jets. These jets can break the liquid flow pattern formed by conventional stirring, such as generating local turbulence in the original laminar state, which helps to better mix liquid components of different densities and viscosities, making the stirring more uniform, reducing the pressure of subsequent sewage chemical treatment, and facilitating the stable operation of the whole system. At the same time, the liquid is diverted through the small holes, so that the resistance encountered by the stirring blade when pushing the liquid is reduced, and the power required for driving the drive motor 7 can also be reduced;

[0054] After being driven, the stirring blade 6497 can change its azimuth and pitch angle in the regulating tank, thereby changing its action posture relative to the fluid inside the stirring container. When it is set in different directions and angles, it will induce different stirring vortex shapes in the stirring container.

[0055] At a certain orientation angle, the stirring blade 6497 can push the fluid to form a compact and high-intensity axial vortex, causing the fluid to generate a strong upward and downward circulation flow in the direction of the stirring axis, effectively achieving rapid mixing and homogenization of the fluid in the depth direction; and when adjusted to another orientation angle, it will induce a large-area vortex ring structure with a radial orientation as the main feature, so that the fluid can be widely diffused and mixed in the circumferential direction within the container cross section, thereby enhancing the material exchange between fluids in different radial regions within the container; when other different orientation angles are set, oblique spiral vortices or complex multi-vortex combination forms can also be generated. These unique vortex patterns can be adjusted according to specific stirring task requirements, such as the mixing characteristics of different sewage concentrations, the stage requirements of the reaction process, etc.

[0056] When the stirring column 9 needs to rotate for stirring operation, the output end of the electromagnetic push rod 621 is retracted to drive the driving frame 1 622 to the side close to the limiting frame 2 62 so that the driving bevel gear 1 63 is driven by the driving frame 1 622 to engage with the driving bevel gear 2 631. At this time, the driving bevel gear 1 63 and the driving bevel gear 2 631 establish an engaged driving relationship, so that the driving bevel gear 2 631 can drive the driving rod 632 to rotate, so that the driving bevel gear 3 633 can rotate with the driving rod 632, and at the same time drive the driving bevel gear 4 634 engaged therewith to rotate, and then drive the mounting ring 635 to rotate through the driving bevel gear 4 634, and then drive the stirring column 9 fixed thereto to rotate through the mounting ring 635 for stirring.

The input end of the fifth water pump (141) extends to the aerobic tank through a pipeline. The output end of the fifth water pump (141) extends to the interior of the sedimentation tank through a pipeline. The sixth water pump (151) is fixedly installed on the top of the inner wall of the sewage treatment integrated tank (1) and is located on the top of the fifth partition (15). The input end of the sixth water pump (151) The sixth water pump (151) is extended to the top of the sedimentation tank through a pipeline and is fixedly installed with a floating block. The output end of the sixth water pump (151) is extended to the top of the filter bin through a pipeline. The mud pump (17) is fixedly installed at the bottom of the inner wall of the sewage treatment integrated tank (1) and is located on the side of the fourth partition (14) close to the fifth partition (15). A sludge settling bucket (18) is provided between the fourth partition (14) and the fifth partition (15). The two sides of the sludge settling bucket (18) are respectively fixedly installed with the fourth partition (14) and the fifth partition (15). The input end of the mud pump (17) is connected to the bottom of the sludge settling bucket (18) through a pipeline. The output end of the mud pump (17) is connected to the external sludge tank for sedimentation and then dehydrated and recycled.An aeration pipe (5) is fixedly installed at the bottom between the third partition (13) and the fourth partition (14); the input end of the aeration pipe (5) is connected to the output end of the external aeration device; the output end of the sixth water pump (151) is connected to a turbidity sensor, which detects the turbidity of the clean water by detecting the light transmittance of the liquid flowing into the pipeline; the turbidity sensor is electrically connected to the external controller via a wire, and is used to detect the turbidity of the clean water pumped out by the sixth water pump (151).
