Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water pollution treatment equipment, and particularly relates to a glyphosate production wastewater treatment equipment based on biological treatment and a process thereof. BACKGROUND

[0002] The glyphosate production wastewater treatment equipment is a professional device for treating wastewater generated in the glyphosate production process. It is usually composed of multiple treatment units. First, large-particle impurities and sand particles in the wastewater are removed through a pretreatment unit such as a grid and a sand trap. Then, the wastewater enters a neutralization and adjustment tank to adjust the pH and water quality, creating stable conditions for subsequent treatment. Then, a biological treatment unit is used to degrade organic pollutants in the wastewater using microorganisms, such as activated sludge method or biofilm method. After that, through deep treatment units such as coagulation and sedimentation, filtration, adsorption and other processes, residual pollutants, suspended solids and color are further removed, so that the treated water meets the discharge standard or reuse requirements.

[0003] Chinese patent CN213327207U discloses a photocatalysis-biofilm-filtration integrated device for treating pesticide wastewater, comprising a reactor main body, a maintenance cover is arranged on one side of the top end of the reactor main body, a water inlet pipe is fixedly installed on one side of the top end of the maintenance cover, and the water inlet pipe penetrates through the inside of the maintenance cover, a PH monitor is fixedly installed on one side of the outer end of the water inlet pipe, a PH adjusting bottle is fixedly installed on one side of the outer end of the water inlet pipe close to the PH monitor, and a TiO2 / GFC recovery port is fixedly installed on one side of the outer end of the reactor main body. The photocatalysis-biofilm-filtration integrated device for treating pesticide wastewater can realize simple process flow, high treatment efficiency, firm photocatalyst loading, easy recovery, long cycle period, low cost, and has certain application prospect in the field of new nicotine-containing pesticide wastewater purification, and brings better use prospect.

[0004] As shown in the above patent, in the existing pesticide wastewater treatment equipment, the wastewater is usually purified by passing through the biological membrane. The biological membrane surface is loaded with a large number of microorganisms. These microorganisms can secrete specific enzymes to hydrolyze the ester bond of organophosphorus pesticides, reduce their toxicity, and form small-molecule organic matter after hydrolysis. Under the action of microbial metabolic activity, the small-molecule organic matter is further decomposed into harmless substances such as carbon dioxide and water. In this process, microorganisms obtain energy and nutrients required for growth and reproduction.

[0005] However, as the device continues to run, a series of problems inevitably occur in the biofilm. On the one hand, suspended solids, colloidal substances and viscous substances produced by microbial metabolism in the wastewater continuously accumulate on the surface of the biofilm, causing the biofilm to gradually thicken, eventually leading to channel blockage. On the other hand, the biofilm is closely combined with the carrier, and the blockage components are complex, including both difficult-to-degrade organic pollutants and microbial aggregates, which greatly increases the difficulty of cleaning the biofilm. Therefore, the biofilm needs to be regularly removed from the device for comprehensive cleaning and maintenance to ensure the stable operation of the sewage treatment device, which is relatively troublesome to clean.

[0006] Therefore, it is necessary to provide a glyphosate production wastewater treatment device based on biological treatment and a process thereof to solve the above technical problems. SUMMARY

[0041] The present application also provides a glyphosate production wastewater treatment process based on biological treatment, comprising the following steps:

[0042] S1. The wastewater is input into the water distributor 3 and dispersed and sprayed out through the water distributor 3, so that the wastewater is uniformly 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. In the process that the wastewater passes through the biofilm 20, the microorganisms in the membrane holes 201 of the biofilm 20 degrade the pollutants in the wastewater, and the treated wastewater is output through the water outlet 4;

[0044] S3. When the biofilm 20 is blocked, the electromagnet 15 is turned on, and the support ring 5 drives the biofilm 20 to rotate reciprocatingly by the transmission assembly, and the water spraying assembly 19 and the electromagnet 15 are driven to move horizontally and reciprocatingly by the driving assembly. When the electromagnet 15 is turned on, the ferrous particles 204 in the biofilm 20 above the electromagnet 15 are attracted, so that the biofilm 20 at the position is concave downward. The biofilm 20 at the concave position is deformed to stretch the membrane holes 201. The water spraying assembly 19 sprays water toward the concave position of the biofilm 20 to clean the membrane holes 201. The biofilm 20 rotates reciprocatingly by the transmission assembly, and the water spraying assembly 19 and the electromagnet 15 move reciprocatingly to change the cleaning position.

[0045] Working principle: When treating glyphosate production wastewater, the wastewater is input into the water distributor 3 through the water inlet 2 and is sprayed out by the water distributor 3 to uniformly distribute on the biofilm 20 and flow downward through the membrane holes 201 of 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 by the water distributor 3 to disinfect the wastewater entering the biofilm 20. In the process of the wastewater passing through the biofilm 20, the microorganisms in the membrane holes 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, the electromagnet 15 is turned on, and the support ring 5 drives the biofilm 20 to rotate reciprocatingly by the transmission assembly, and the water spraying assembly 19 and the electromagnet 15 are driven to move horizontally and reciprocatingly by the driving assembly. When the electromagnet 15 is turned on, the ferrous particles 204 in the biofilm 20 above the electromagnet 15 are attracted, so that the biofilm 20 at the position is concave downward. The biofilm 20 at the concave position is deformed to stretch the membrane holes 201. The water spraying assembly 19 sprays water toward the concave position of the biofilm 20 to clean the membrane holes 201.

[0046] When cleaning, the output end of the motor 9 rotates reciprocatingly to drive the second shaft 12 to rotate reciprocatingly. When the second shaft 12 rotates, the second spur gear 14 drives the rack 16 to move reciprocatingly to drive the electromagnet 15 fixedly connected with the rack 16 to move reciprocatingly. When the rack 16 moves, the connecting rod 17 drives the driving rod 18 to move synchronously to drive the water spraying assembly 19 to move synchronously, so that the water spraying assembly 19 and the electromagnet 15 are driven to move horizontally and reciprocatingly by the driving assembly. When the second shaft 12 rotates, the second bevel gear 13 drives the first bevel gear 11 to rotate reciprocatingly to drive the first shaft 10 to rotate reciprocatingly. When the first shaft 10 rotates reciprocatingly, the first spur gear 7 drives the gear ring 6 to rotate reciprocatingly to drive the biofilm 20 to rotate reciprocatingly by the support ring 5, so that the support ring 5 is driven to rotate reciprocatingly by the transmission assembly.

[0047] When the water spraying assembly 19 works, 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 connecting port 196, and then input into the water spraying head 192 through the flow channel on the piston 193 and the plug rod 194, and then dispersed and sprayed through the conical structure at the bottom of the water spraying head 192, so as to adapt to the concave structure formed at the position to be cleaned of the biofilm 20, so that the biofilm 20 is better cleaned, and when water exists in the cylinder 191, the piston 193 is driven to move downward under the action of water pressure to overcome 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 then the water spraying head 192 enters the concave part formed on the biofilm 20, so that the distance between the water spraying head 192 and the concave part of the biofilm 20 is reduced, the water pressure acting on the biofilm 20 is increased, and the cleaning effect is improved.

The biofilm at the sink point deforms, causing the membrane pores to stretch and deform. In conjunction with the water spray component, water is sprayed towards the sink point of the biofilm to clean the membrane pores.

9. A treatment process for glyphosate production wastewater based on biological treatment, employing the glyphosate production wastewater treatment equipment based on biological treatment as described in any one of claims 1-8, characterized in that, Includes the following steps: S1. Wastewater is fed into the distributor and sprayed out through the distributor, so that the wastewater is evenly distributed on the biofilm and flows downward through the membrane pores of the biofilm to pass through the biofilm. S2. During the process of wastewater passing through the biofilm, the microorganisms in the pores of the biofilm degrade the pollutants in the wastewater, and the treated wastewater is discharged through the outlet. S3. When the biofilm becomes clogged, the electromagnet is activated, and the support ring is driven by the transmission component to rotate the biofilm back and forth. At the same time, the water spray component and the electromagnet are driven by the drive component to move horizontally back and forth synchronously. When the electromagnet is activated, it attracts the iron particles in the biofilm above it, causing the biofilm to sink downwards. The biofilm at the sink point deforms, causing the membrane pores to stretch and deform. The water spray component sprays water towards the sink point of the biofilm to clean the membrane pores. The rotation of the biofilm, combined with the reciprocating motion of the water spray component and the electromagnet, changes the cleaning position.
