Description

Technical Field

[0001] The present invention relates to the technical field of water pollution treatment equipment, and particularly to a sewage treatment equipment and process for glyphosate production based on biological treatment. Background Technique

[0002] The sewage treatment equipment for glyphosate production is a professional device for treating the sewage generated in the glyphosate production process. It usually consists of multiple treatment units. First, through pretreatment units such as grids and grit chambers, large particle impurities and sand grains in the sewage are removed; then it enters the neutralization and adjustment tank to adjust the pH value and water quality of the sewage to create stable conditions for subsequent treatment. Then, a biological treatment unit is adopted to utilize microorganisms to degrade organic pollutants in the sewage, such as the activated sludge method or the biofilm method. After that, through advanced treatment units such as coagulation sedimentation, filtration, adsorption and other processes, residual pollutants, suspended solids and chromaticity are further removed, so that the treated water meets the discharge standard or the reuse requirement.

[0003] Chinese Patent CN213327207U discloses a photocatalysis-biofilm-filtration integrated device for treating pesticide wastewater, including a reactor main body. One side of the top of the reactor main body is provided with a maintenance cover. One side of the top of the maintenance cover is fixedly installed with a water inlet pipe, and the water inlet pipe penetrates through one side of the inside of the maintenance cover. One side of the outer end of the water inlet pipe is fixedly installed with a PH monitor, and one side of the outer end of the water inlet pipe close to the PH monitor is fixedly installed with a PH adjustment bottle. One side of the outer end of the reactor main body is fixedly installed with a TiO2 / GFC recovery port. The disclosed photocatalysis-biofilm-filtration integrated device for treating pesticide wastewater can make the overall device have a simple process flow, high treatment efficiency, the photocatalyst is firmly loaded and easy to recover, can be used for a long cycle, low cost, and has a certain application prospect in the field of purifying wastewater containing neonicotinoid pesticides, bringing a better use prospect.

[0004] As shown in the above patent, in the existing pesticide sewage treatment equipment, the sewage is often purified by passing through the biofilm. A large number of microorganisms are loaded on the surface of the biofilm. These microorganisms can secrete specific enzymes to hydrolyze the ester bond of the organophosphorus pesticide and reduce its toxicity. The small molecule organic substances formed after hydrolysis will be further decomposed into harmless substances such as carbon dioxide and water under the action of the microbial metabolic activities. In this process, the microorganisms obtain the energy and nutrients required for growth and reproduction.

[0005] However, with the continuous operation of the equipment, a series of problems inevitably occur in the biofilm. On the one hand, suspended solids, colloidal substances in the wastewater, and viscous substances produced by microbial metabolism continuously accumulate on the surface of the biofilm, causing the biofilm to gradually thicken and eventually leading to channel blockage. On the other hand, the biofilm is tightly bonded to the carrier, and the components of the blockage are complex, including both organic pollutants that are difficult to degrade and biological flocs formed by microbial aggregation, which greatly increases the difficulty of cleaning the biofilm. Therefore, it is necessary to regularly disassemble the biofilm from the equipment for comprehensive cleaning and maintenance to ensure the stable operation of the sewage treatment equipment, but the cleaning is rather troublesome.

[0006] Therefore, it is necessary to provide a glyphosate production sewage treatment equipment and its process based on biological treatment to solve the above technical problems. Summary of the Invention

Detailed implementation manner

[0031] The following will further describe the present invention in conjunction with the drawings in the embodiments of the present invention.

[0032] Please refer to Figures 1 to 8, in the embodiments of the present invention, a sewage treatment device for glyphosate production based on biological treatment includes a treatment tank 1, a water distributor 3 fixedly arranged at the top of the inner cavity of the treatment tank 1, and a support ring 5 rotatably arranged in the middle of the inner cavity of the treatment tank 1. One side of the bottom of the treatment tank 1 is communicated with a water outlet 4. A biological membrane 20 is installed inside the support ring 5. The biological membrane 20 is made of an elastic material and can be made of materials such as polyurethane, polyethersulfone, and polyvinyl alcohol. Iron particles 204 are embedded and installed inside the biological membrane 20, and the iron particles 204 are evenly distributed in the biological membrane 20. A plurality of membrane holes 201 are formed in the biological membrane 20, and a load-bearing wire 203 is arranged in the membrane holes 201. The load-bearing wire 203 is randomly distributed in a net structure in the membrane holes 201, and microorganisms are attached to the load-bearing wire 203. The load-bearing wire 203 is made of polyester fiber. When preparing the biological membrane 20, the polyester fiber is sprayed into the membrane holes 201 on the biological membrane 20 by a spinning device. A transmission component is arranged in the treatment tank 1 for driving the support ring 5 to rotate self. A water spraying component 19 and an electromagnet 15 are respectively arranged above and below the support ring 5. The water spraying component 19 is located directly above the electromagnet 15. A driving component is arranged on the treatment tank 1 for driving the water spraying component 19 and the electromagnet 15 to move horizontally synchronously. When treating glyphosate production sewage, the sewage is input into the water distributor 3 and sprayed out dispersedly through the water distributor 3, so that the sewage is evenly distributed on the biological membrane 20 and flows downward through the membrane holes 201 on the biological membrane 20 to pass through the biological membrane 20. During the process of the sewage passing through the biological membrane 20, the microorganisms in the membrane holes 201 of the biological membrane 20 degrade the pollutants in the sewage, and the treated sewage is output through the water outlet 4. When the biological membrane 20 is blocked, the electromagnet 15 is turned on, and the support ring 5 is driven by the transmission component to drive the biological membrane 20 to rotate reciprocally. At the same time, the water spraying component 19 and the electromagnet 15 are driven by the driving component to move horizontally and reciprocally synchronously. When the electromagnet 15 is turned on, it attracts the iron particles 204 in the biological membrane 20 above it, causing the biological membrane 20 to sag downward at this position. The biological membrane 20 at the sagging part deforms, causing the membrane holes 201 to stretch and deform. The water spraying component 19 sprays water towards the sagging part of the biological membrane 20 to clean the membrane holes 201. The rotation of the biological membrane 20 is combined with the reciprocating movement of the water spraying component 19 and the electromagnet 15 to change the cleaning position.

[0033] The present invention utilizes the response characteristics of an elastic biofilm 20 embedded with iron particles 204. By attracting and inducing local deformation of the biofilm 20 with an electromagnet 15, a stretching effect is generated on the membrane pores 201, effectively loosening and peeling off blockages such as colloidal substances and flocs attached inside the membrane pores 201. Combining the self-rotation of the biofilm 20 with the dynamic cleaning of the water spraying assembly 19, a dual plugging removal mechanism of physical deformation and hydraulic scouring is achieved. Compared with the traditional static cleaning method, the blockage removal efficiency is increased by more than 80%, effectively avoiding the channel blockage on the biofilm 20. Through the coordinated control of the self-rotation of the support ring 5 and the horizontal movement of the water spraying assembly 19, a cleaning path covering the entire surface of the biofilm 20 is formed. The synchronous displacement of the electromagnet 15 and the water spraying assembly 19 ensures no cleaning dead angle, enabling the equipment to complete in-depth cleaning during continuous operation without stopping to disassemble the biofilm 20, reducing the maintenance time by 90% and significantly reducing the operation and maintenance costs.

[0034] In this embodiment, preferably, the transmission assembly includes a mounting seat 8 fixedly installed on the inner wall of the treatment tank 1, a first rotating shaft 10 rotatably installed on the mounting seat 8, a first straight gear 7 fixedly sleeved on the top end of the first rotating shaft 10, and a toothed ring 6 fixedly installed on the bottom wall of the support ring 5. The first straight gear 7 meshes with the toothed ring 6. The driving assembly includes a connecting rod 17, a rack 16, and a driving rod 18. The rack 16 and the driving rod 18 penetrate through the tank wall of the treatment tank 1. The rack 16 and the driving rod 18 are both horizontally arranged and parallel to each other. One end of the rack 16 and the driving rod 18 is fixedly connected through the connecting rod 17. The other end of the rack 16 is fixedly connected to the electromagnet 15, and the other end of the driving rod 18 is connected to the water spraying assembly 19. The driving assembly further includes a motor 9 fixedly installed on the mounting seat 8, a second rotating shaft 12 rotatably connected to the mounting seat 8, and a second straight gear 14 fixedly sleeved on the second rotating shaft 12. The motor 9 is a forward and reverse motor 9, so that the second rotating shaft 12 can rotate reciprocally. The output end of the motor 9 is fixedly connected to the second rotating shaft 12. The second straight gear 14 meshes with the rack 16. A first bevel gear 11 is fixedly sleeved on the bottom end of the first rotating shaft 10, and a second bevel gear 13 is fixedly sleeved on the second rotating shaft 12. The first bevel gear 11 meshes with the second bevel gear 13. When cleaning the biological film 20, control the output end of the motor 9 to rotate reciprocally, thereby driving the second rotating shaft 12 to rotate reciprocally. When the second rotating shaft 12 rotates, it drives the rack 16 to move reciprocally through the second straight gear 14, thereby driving the electromagnet 15 fixedly connected to the rack 16 to move reciprocally. Moreover, when the rack 16 moves, it drives the driving rod 18 to move synchronously through the connecting rod 17, and further drives the water spraying assembly 19 to move synchronously, so as to realize driving the water spraying assembly 19 and the electromagnet 15 to move horizontally and reciprocally synchronously through the driving assembly. At the same time, when the second rotating shaft 12 rotates, it drives the first bevel gear 11 to rotate reciprocally through the second bevel gear 13, thereby driving the first rotating shaft 10 to rotate reciprocally. When the first rotating shaft 10 rotates reciprocally, it drives the toothed ring 6 to rotate reciprocally through the first straight gear 7, thereby driving the biological film 20 to rotate reciprocally through the support ring 5, so as to realize driving the support ring 5 to rotate reciprocally through the transmission assembly. By only setting one motor 9, the reciprocal rotation of the biological film 20 and the synchronous horizontal reciprocal movement of the water spraying assembly 19 and the electromagnet 15 are realized, and the production cost of the equipment is reduced. It should be noted that when the rack 16 rotates reciprocally once, the number of rotations of the support ring 5 in the forward and reverse directions is greater than 3, so as to ensure that all positions of the biological film 20 can be cleaned.

[0035] In this embodiment, preferably, an aeration assembly is provided at the bottom of the inner cavity of the treatment tank 1. The aeration assembly includes an aeration pipe 22 and an aeration head 23 provided on the aeration pipe 22. The aeration head 23 is communicated with the aeration pipe 22. The aeration pipe 22 is of a double-ring structure. An air inlet pipe 24 is communicated with one side of the aeration pipe 22, and the air inlet pipe 24 penetrates through the tank wall of the treatment tank 1. During use, an air pump is used to input air through the air inlet pipe 24, and the air is ejected from the aeration head 23 through the aeration pipe 22, so as to supply oxygen to the microorganisms in the biofilm 20.

[0036] In this embodiment, preferably, a water inlet 2 is communicated with the top end of the water distributor 3, and the water inlet 2 penetrates through the top wall of the treatment tank 1. The sewage to be biologically treated is input into the water distributor 3 through the water inlet 2 and ejected through the water distributor 3, so that the sewage uniformly covers the biofilm 20.

[0037] In this embodiment, preferably, a telescopic sealing sleeve 21 is sleeved on the rack 16. One end of the telescopic sealing sleeve 21 is fixedly connected to the outer wall of the treatment tank 1, and the other end of the telescopic sealing sleeve 21 is fixedly connected to the connecting rod 17. The gap between the rack 16 and the treatment tank 1 is sealed by the telescopic sealing sleeve 21 to prevent the sewage in the treatment tank 1 from overflowing through this gap.

[0038] In this embodiment, preferably, an annular base 25 is fixedly installed at the top of the inner peripheral wall of the treatment tank 1. An ultraviolet lamp tube 26 is fixedly installed in the annular base 25. The ultraviolet lamp tube 26 is of an annular structure. The ultraviolet light shines on the sewage ejected by the water distributor 3, which can disinfect the sewage entering the biofilm 20 and prevent the miscellaneous bacteria in the sewage from affecting the microorganisms on the biofilm 20.

[0039] In this embodiment, preferably, a rubber ring 202 is arranged inside the pore wall of the membrane pore 201, and the load-bearing wire 203 is arranged inside the rubber ring 202. The rubber ring 202 is made of a material with a relatively large coefficient of thermal expansion. When the biofilm 20 is cleaned with warm water, as the temperature rises, the aperture of the rubber ring 202 increases, making it easier for the impurities blocked in the membrane pore 201 to fall off, thereby improving the cleaning effect.

[0040] Please refer to Figures 2 to 6, in the embodiment of the present invention, the water spraying assembly 19 includes a cylinder 191, a piston 193 slidably installed inside the cylinder 191, and a water spraying head 192 arranged below the cylinder 191. The cylinder 191 is fixedly connected to one end of the driving rod 18 extending into the treatment tank 1. A plug rod 194 is fixedly installed at the top of the water spraying head 192, and the top of the plug rod 194 is fixedly connected to the piston 193. A flow channel communicating with the water spraying head 192 is formed inside the piston 193 and the plug rod 194. The bottom end of the piston 193 is fixedly connected to a spring 195, and the bottom end of the spring 195 is fixedly connected to the bottom wall of the cylinder 191. A connection port 196 is communicated and arranged at the top end of the cylinder 191; a heating element 198 is fixedly installed on the tank wall of the treatment tank 1. A water inlet pipe 199 is communicated and arranged on one side of the heating element 198, and a telescopic pipe 197 is communicated and arranged on the other side of the heating element 198. One end of the telescopic pipe 197 away from the heating element 198 is communicated with the connection port 196; heating structures such as electric heating wires are arranged in the heating element 198 to heat the cleaning water input at the water inlet pipe 199, and the water temperature is controlled below 50°. A temperature sensor is arranged in the heating element 198 to detect the water temperature to prevent the water temperature from being too high. When cleaning the biofilm 20, the cleaning water is input through the water inlet pipe 199, heated by the heating element 198 and then input into the telescopic pipe 197, and then input into the cylinder 191 through the connection port 196. Subsequently, it is input into the water spraying head 192 through the flow channels formed in the piston 193 and the plug rod 194, and is dispersed and sprayed through the conical structure at the bottom of the water spraying head 192 to adapt to the concave structure formed at the position of the biofilm 20 to be cleaned, so as to better clean the biofilm 20. Moreover, when there is water in the cylinder 191, under the action of water pressure, the piston 193 is pushed to move downward against the elastic force of the spring 195, so that the piston 193 drives the water spraying head 192 to move downward through the plug rod 194, and further enables the water spraying head 192 to enter the concave part formed on the biofilm 20, reducing the distance between the water spraying head 192 and the concave part of the biofilm 20, and thus increasing the water pressure acting on the biofilm 20 to improve the cleaning effect.

[0041] The present invention also provides a glyphosate production sewage treatment process based on biological treatment, including the following steps:

[0042] S1. Input the sewage into the water distributor 3 and disperse and spray it through the water distributor 3, so that the sewage is evenly distributed on the biofilm 20 and flows downward through the membrane holes 201 on the biofilm 20 to pass through the biofilm 20;

[0043] S2. During the process of the sewage passing through the biofilm 20, the microorganisms in the membrane holes 201 of the biofilm 20 degrade the pollutants in the sewage, and the treated sewage is output through the water outlet 4;

[0044] S3. When the biofilm 20 is blocked, turn on the electromagnet 15, and drive the support ring 5 to drive the biofilm 20 to rotate reciprocally through the transmission component. At the same time, drive the water spraying component 19 and the electromagnet 15 to move horizontally reciprocally synchronously through the drive component. When the electromagnet 15 is turned on, it attracts the iron particles 204 in the biofilm 20 above it, causing the biofilm 20 to sag downward at this position. The biofilm 20 at the sagging part deforms, causing the membrane pores 201 to stretch and deform. Cooperate with the water spraying component 19 to spray water towards the sagging part of the biofilm 20 to clean the membrane pores 201. Through the rotation of the biofilm 20 and the reciprocating movement of the water spraying component 19 and the electromagnet 15, the cleaning position is changed.

[0045] Working principle: When treating glyphosate production wastewater, the wastewater is input into the water distributor 3 through the water inlet 2 and sprayed out dispersedly through the water distributor 3, so that the wastewater is evenly distributed on the biofilm 20 and flows downward through the membrane pores 201 on the biofilm 20 to pass through the biofilm 20. At the same time, the ultraviolet light emitted by the ultraviolet lamp tube 26 shines on the wastewater sprayed out by the water distributor 3, which can disinfect the wastewater entering the biofilm 20. During the process of the wastewater passing through the biofilm 20, the microorganisms in the membrane pores 201 of the biofilm 20 degrade the pollutants in the wastewater. The treated wastewater is output through the water outlet 4. When the biofilm 20 is blocked, turn on the electromagnet 15, and drive the support ring 5 to drive the biofilm 20 to rotate reciprocally through the transmission component. At the same time, drive the water spraying component 19 and the electromagnet 15 to move horizontally reciprocally synchronously through the drive component. When the electromagnet 15 is turned on, it attracts the iron particles 204 in the biofilm 20 above it, causing the biofilm 20 to sag downward at this position. The biofilm 20 at the sagging part deforms, causing the membrane pores 201 to stretch and deform. Cooperate with the water spraying component 19 to spray water towards the sagging part of the biofilm 20 to clean the membrane pores 201;

[0046] During cleaning, control the output end of the motor 9 to rotate reciprocally, thereby driving the second rotating shaft 12 to rotate reciprocally. When the second rotating shaft 12 rotates, it drives the rack 16 to move reciprocally through the second spur gear 14, thereby driving the electromagnet 15 fixedly connected to the rack 16 to move reciprocally. And when the rack 16 moves, it drives the driving rod 18 to move synchronously through the connecting rod 17, and further drives the water spraying component 19 to move synchronously, so as to realize driving the water spraying component 19 and the electromagnet 15 to move horizontally reciprocally synchronously through the drive component. At the same time, when the second rotating shaft 12 rotates, it drives the first bevel gear 11 to rotate reciprocally through the second bevel gear 13, thereby driving the first rotating shaft 10 to rotate reciprocally. When the first rotating shaft 10 rotates reciprocally, it drives the gear ring 6 to rotate reciprocally through the first spur gear 7, thereby driving the biofilm 20 to rotate reciprocally through the support ring 5, so as to realize driving the support ring 5 to rotate reciprocally through the transmission component;

[0047] When the water spraying assembly 19 works, clean water is input through the water inlet pipe 199, heated by the heating element 198 and then input into the telescopic pipe 197. Then it is input into the cylinder 191 through the connection port 196, and then input into the water spray head 192 through the flow channels formed on the piston 193 and the piston rod 194, and is dispersed and sprayed through the conical structure at the bottom of the water spray head 192 to adapt to the concave structure formed at the position of the biofilm 20 to be cleaned, so as to better clean the biofilm 20. Moreover, when there is water in the cylinder 191, under the action of water pressure, the piston 193 is pushed downward to overcome the elastic force of the spring 195, so that the piston 193 drives the water spray head 192 downward through the piston rod 194, and further makes the water spray head 192 enter the concave part formed on the biofilm 20, reducing the distance between the water spray head 192 and the concave part of the biofilm 20, thereby increasing the water pressure acting on the biofilm 20 to improve the cleaning effect.

[0048] The above is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
