Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to a sewage treatment process and a device thereof based on synergy. Background Art

[0002] Artificial fillers play an important role in sewage treatment. They provide an environment for microorganisms to attach and grow through their specific structure and properties, thereby enhancing the ability to degrade organic matter and other harmful substances in sewage. There are many types of artificial fillers, and the common ones are modified diatomaceous earth, modified zeolite, sodium montmorillonite, etc. These fillers usually have a large specific surface area and porosity, which is conducive to the attachment and growth of microorganisms, and also have good mechanical strength and chemical stability.

[0003] The existing technology of using fillers for sewage treatment has the following shortcomings:

[0004] When the organic load of the influent is high and the conditions for microbial growth are suitable, the biofilm will grow and proliferate rapidly, gradually blocking the gaps between the surface areas of the fillers, resulting in a reduction in the contact area between the biofilm on the filler and the sewage. Although the amount of biofilm on the filler has increased, most of the surface area of ​​the filler is blocked by the proliferating biofilm, and the effective biofilm surface area on the filler is reduced, resulting in the inability of the sewage containing nutrients to effectively contact these biofilms, and the biomass directly involved in the sewage purification reaction is reduced, and the sewage purification effect does not reach the expected goal.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] Embodiment 1:

[0035] A wastewater treatment process based on synergy, such as Figure 1-Figure 7 As shown, this is achieved through the synergistic effect of artificial fillers and plant roots.

[0036] Embodiment 2:

[0037] A sewage treatment device based on synergy, such as Figure 1-Figure 7 As shown, it includes a treatment pool 1, wherein a planting bed 2 is arranged inside the treatment pool 1, and the planting bed 2 is arranged on the inner wall of the bottom of the treatment pool 1, and a water outlet 3 is respectively arranged on the top and bottom of one side of the treatment pool 1, and a water inlet 6 is arranged at the bottom of the other side of the treatment pool 1, and a valve control component 7 is connected to the outside of the water inlet 6, and an artificial filler is arranged in the space between the aeration pipe 5 and the planting bed 2 of the treatment pool 1, and the artificial filler is any one of modified diatomaceous earth, modified zeolite, and sodium montmorillonite with attached microorganisms.

[0038] The planting bed 2 is composed of a plurality of planting boards 8 on which plants are planted. The two planting boards 8 at the end are rotatably connected to the inner wall of the treatment tank 1 via a hinge shaft 9 , and the two adjacent planting boards 8 are connected via a hinge 10 .

[0039] An integrated driving unit 4 is provided at the bottom of the treatment tank 1 .

[0040] Each set of hinges 10 includes a waist-shaped ring 12 and two limiting columns 11. The two limiting columns 11 are respectively welded to the ends of two adjacent planting plates 8, and the limiting columns 11 are movably limited and matched with the inner wall of the waist-shaped ring 12.

[0041] This device arranges artificial fillers in the suspended growth of artificial fillers and uses natural plant roots to replace part of the artificial fillers, so as to improve the biodiversity in the treatment pool 1, build a good microbial ecosystem, maintain benign growth and circulation, and ensure the stable treatment capacity of biological treatment.

[0042] In order to solve the problem of processing effect, such as Figure 4 As shown, the integrated driving unit 4 includes two main shafts 16 rotatably connected to the inner side of the bottom of the treatment pool 1 and a connecting shaft 13 connected to the opposite side of the two main shafts 16 through a crankshaft 15. A connecting rod 14 is rotatably connected to the inner side of the eccentric part of the crankshaft 15, and the other end of the connecting rod 14 is rotatably connected to the bottom outer wall of one of the planting plates 8. In this embodiment, preferably, the other end of the connecting rod 14 is rotatably connected to the bottom outer wall of the middle planting plate 8.

[0043] During the sewage treatment process, when the main shaft 16 rotates, it can drive the crankshaft 15 to rotate, thereby driving the planting board 8 to move up and down through the connecting rod 14, so that the multiple planting boards 8 and the plants planted on the planting boards 8 float up and down.

[0044] The device, by configuring the planting bed 2 to be composed of a plurality of planting plates 8, and utilizing the connecting rod 14 to drive the planting plates 8 so that the planting plates 8 fluctuate up and down, thereby cooperating with the aeration pipe 5 at the bottom for aeration, so that the microorganisms can be in contact with oxygen more evenly and fully, thereby increasing the sewage treatment effect.

[0045] To solve the intake control problem, such as Figure 5 As shown, the integrated driving unit 4 also includes an elastic hose 21 and a plurality of squeezing rollers 20. A plurality of support plates 18 are welded to the outer wall of the main shaft 16. The plurality of squeezing rollers 20 are rotatably connected to the support plates 18 via a rotating shaft 19. The elastic hose 21 is fixed to the inner wall of the treatment tank 1, and the squeezing rollers 20 are squeezed and matched with the elastic hose 21. One end of the elastic hose 21 is connected to the atmosphere, and the other end of the elastic hose 21 is connected to the aeration pipe 5.

[0046] The integrated driving unit 4 further includes a motor 22 fixed to the outer wall of the treatment tank 1 , and the output shaft of the motor 22 is connected to the end of the main shaft 16 through a coupling.

[0047] When the main shaft 16 rotates, it can drive the support plate 18 to rotate, thereby driving the squeezing roller 20 to roll along the elastic hose 21. When the squeezing roller 20 rolls along the elastic hose 21, the air in the elastic hose 21 will be squeezed into the inside of the aeration pipe 5, and then the squeezed elastic hose 21 will restore its shape due to its own elasticity, and then use negative pressure to inhale air, and so on and so forth to complete continuous air supply.

[0048] This device, by providing an integrated driving unit 4, can utilize the motor 22 to simultaneously drive the planting plate 8 to float up and down and the air intake of the aeration pipe 5, thereby reducing the power source layout, increasing linkage and simplifying the control logic, and also making the structure compact.

[0049] In the streamlined treatment process, if the water inlet speed is greater than the drainage speed, the sewage in the treatment pool 1 will gradually fill up and overflow. If the water inlet speed is less than the drainage speed, the sewage in the treatment pool 1 will gradually decrease, and the treatment efficiency will be low. Based on this, in order to solve the problem of inlet and outlet water balance, Figure 6 , 7 As shown, the valve control component 7 includes a sensing component 23 , a control component 24 and an opening valve component 25 .

[0050] The opening valve assembly 25 includes a valve housing 35 fixed to the end of the water inlet 6 and a valve core 36 rotatably connected to the inner wall of the valve housing 35. The valve core 36 can be rotated to control the flow channel overlapping area between the valve core 36 and the valve housing 35, thereby controlling the opening to achieve the purpose of throttling.

[0051] The control assembly 24 includes a cylinder body 30, a piston 31 and a valve stem 34. The valve stem 34 is welded to the top outer wall of the valve core 36. The cylinder body 30 is welded to the top outer wall of the valve housing 35. The piston 31 is slidably connected to the inner wall of the cylinder body 30. The bottom outer wall of the piston 31 is fixed with a ring seat 17 by bolts. A spiral groove 32 is opened on the outer wall of the valve stem 34. A limit column 33 that is movably limited to the spiral groove 32 is fixedly embedded in the inner wall of the ring seat 17.

[0052] When the second piston 31 slides up and down relative to the second cylinder body 30, it can drive the ring seat 17 to slide up and down, thereby driving the second limit column 33 to slide up and down relative to the spiral groove 32, so that the valve stem 34 drives the valve core 36 to rotate and change the opening.

[0053] The sensing assembly 23 includes a cylinder body 27 welded and connected to the top of the water inlet 6 and a piston 26 slidably connected to the inner wall of the cylinder body 27, a spring 28 is buckled on the top outer wall of the piston 26, the other end of the spring 28 is buckled on the top lower surface of the cylinder body 27, and the top of the cylinder body 27 is connected to the top of the cylinder body 2 30 through a connecting pipe 29.

[0054] When there is a difference between the water inlet speed and the water outlet speed, the liquid level in the treatment tank 1 will change, causing the water inlet pressure at the water inlet 6 to change. The piston 26 moves under the combined influence of the water inlet pressure and the spring 28, causing the inner cavity pressure of the cylinder 1 27 to change, which is transmitted to the inner cavity of the cylinder 2 30 through the connecting pipe 29, causing the piston 2 31 to move.

[0055] When the present embodiment is in use, the sewage can be transported to the treatment pool 1 through the valve control assembly 7. During the streamlined treatment, the upper water outlet 3 is opened and the bottom water outlet 3 is closed. The sewage is treated by the microorganisms on the filler and the plant roots and then discharged along the water outlet 3. During the sewage treatment process, when the main shaft 16 rotates, it can drive the crankshaft 15 to rotate, thereby driving the planting plate 8 to move up and down through the connecting rod 14, so that the multiple planting plates 8 and the plants planted on the planting plates 8 float up and down. When the main shaft 16 rotates, it can drive the support plate 18 to rotate, thereby driving the squeezing roller 20 to roll along the elastic hose 21. When the squeezing roller 20 rolls along the elastic hose 21, it squeezes the air in the elastic hose 21 into the inside of the aeration pipe 5, and then the squeezed elastic hose 21 is restored to its shape by its own elasticity, and then the air is sucked in by negative pressure. Gas is supplied repeatedly in this way to complete continuous gas supply. When there is a difference between the water inlet speed and the water outlet speed, the internal liquid level of the treatment pool 1 will change, thereby changing the water inlet pressure at the water inlet 6. The piston 26 is moved by the combined influence of the water inlet pressure and the spring 28, thereby changing the inner cavity pressure of the cylinder body 27, which is transmitted to the inner cavity of the cylinder body 2 30 through the connecting pipe 29, so that the piston 2 31 moves. When the piston 2 31 slides up and down relative to the cylinder body 2 30, it can drive the ring seat 17 to slide up and down, thereby driving the limit column 2 33 to slide up and down relative to the spiral groove 32, so that the valve stem 34 drives the valve core 36 to rotate. The valve core 36 can be rotated to control the flow channel overlapping area of ​​the valve core 36 and the valve housing 35, thereby controlling the opening and achieving the purpose of throttling. After the treatment is completed, the water outlet 3 at the bottom is opened to fully discharge the sewage.

[0056] The device, by setting an opening valve assembly 25, can control the overlapping area of ​​the flow channel between the valve core 36 and the valve housing 35 by rotating the valve core 36, so as to control the opening and achieve the purpose of throttling, thereby effectively controlling the water inlet speed, making the water inlet speed match the water discharge speed, and ensuring the stability of the treatment.

[0057] This device, by setting up a sensing component 23 and a control component 24, which are combined with each other, can utilize the characteristics of liquid level changes caused by the difference between water inlet speed and water discharge speed, and then combine the liquid level change to cause the water inlet pressure of the water inlet 6 to achieve automatic adjustment of the opening.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
