Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a glyphosate production waste salt wastewater treatment system and process. Background Technology

[0002] Currently, in the field of glyphosate wastewater treatment, existing glyphosate wastewater treatment devices often neglect the pretreatment of wastewater. Pretreatment is a crucial part of the wastewater treatment process, which includes steps such as pH adjustment and removal of suspended solids. However, in existing technologies, this part of the work is often overlooked. pH adjustment is crucial for the efficiency of subsequent chemical reactions and biological treatments, while the removal of suspended solids can reduce the load on subsequent treatment processes and improve the overall treatment effect.

[0003] A search revealed a Chinese patent with publication number CN117023881A, which discloses a wastewater treatment device for environmental protection. This patent includes a wastewater treatment tank, an inlet pipe, a rotatable wastewater processor, a drive unit, a first brush, a magnetic rod, a wastewater treatment pool, a liftable filter plate, a unclogging needle, and a drain pipe. The device is designed to ensure that the filter screen and filter plate maintain high-efficiency filtration for extended periods. However, this patent treats wastewater entirely through physical filtration using a filter screen. In reality, wastewater is diverse, and different types of wastewater require the removal of different substances. Therefore, physical filtration alone is insufficient. To meet the actual needs of wastewater treatment, taking the treatment of wastewater generated by glyphosate as an example, the suspended solids content in glyphosate wastewater is often high, and the properties of the suspended solids may vary depending on the source of the wastewater and the production process. However, existing treatment processes often adopt a uniform treatment method, which cannot separate the wastewater according to the level of suspended solids and then use different treatment methods. This non-targeted treatment method not only reduces the treatment efficiency, but also causes waste of resources and secondary pollution to the environment. It cannot make full use of the separation method to treat wastewater with different suspended solids content separately through corresponding electrocatalysis and photocatalysis. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art and provide a glyphosate production wastewater treatment system and process.

[0035] This invention also discloses a glyphosate production wastewater treatment process, which uses the above-mentioned glyphosate production wastewater treatment system and includes the following steps:

[0036] S1. Wastewater enters the pretreatment cylinder through the inlet pipe. Inside the pretreatment cylinder, the pH value of the wastewater is adjusted to neutral or weakly alkaline by the pH adjustment component. Then, the coagulant is mixed with the wastewater by the coagulant addition component, which promotes the formation of flocs from suspended solids, colloids and some organic matter in the wastewater, thereby reducing the load on subsequent treatment.

[0037] S2. Wastewater in the filter cartridge retains residual organic matter, heavy metal ions and fine particles through the adsorption and filtration components.

[0038] S3. Wastewater that passes only through the second filter screen when passing through the separator is high suspended solids wastewater and enters the electrocatalytic cylinder through the first separator for treatment. Wastewater that passes through both the second and third filters and is low suspended solids wastewater enters the photocatalytic cylinder through the second separator for treatment.

[0039] S4. The wastewater treated by the photocatalytic cylinder or the electrocatalytic cylinder is collected in the evaporation crystallization cylinder for evaporation to remove moisture and concentrate salt.

[0040] By adopting the above technical solution, the present invention has the following beneficial effects:

[0041] By incorporating a pH adjustment component and a coagulant addition component within the pretreatment tank, the pH adjustment component uses a pH sensor to determine the wastewater's pH value. Acidic and / or alkaline solutions from the pH adjustment solution are then introduced into the corresponding adjustment tank, driving a pressing block within the tank to move linearly along the axis of a reciprocating screw. As the pressing block moves downwards, the corresponding solution introduced into the adjustment tank is extruded through the outlet and sprayed into the wastewater to mix. The extrusion of the solution into the wastewater accelerates the mixing process. This process is repeated until the pH sensor displays the wastewater's pH value within a preset range. After pH adjustment, the coagulant in the coagulant tank is discharged into the wastewater via the coagulant addition component. A rotating agitator accelerates the reaction between the coagulant and the wastewater. Ultimately, some impurities in the wastewater react with the coagulant to form flocculent deposits that settle below the first filter screen, thus completing the wastewater pretreatment process and facilitating subsequent wastewater treatment.

[0042] Through the design of a rotating sleeve and a storage mesh cylinder, wastewater enters the filter cylinder after pretreatment. Activated biochar is placed inside the storage mesh cylinder. When the opening of the rotating sleeve is located within the filter chamber of the filter cylinder, the wastewater directly contacts the activated biochar in the storage mesh cylinder, allowing the activated biochar to adsorb and filter the wastewater. After adsorption and filtration are complete, the wastewater enters the separatory cylinder. At this point, the rotating sleeve rotates, moving the opening into the regeneration chamber. Inside the regeneration chamber, the activated biochar in the storage mesh cylinder is regenerated through aeration. Simultaneously, a rotating rod is installed inside the storage mesh cylinder, which drives the entire storage mesh cylinder and the activated biochar inside it to rotate around the rod's center within the rotating sleeve. When the storage mesh cylinder rotates within the filter chamber, it increases the contact area between the activated biochar and the wastewater. When it rotates within the regeneration chamber, it increases the contact area with oxidants such as pure oxygen and ozone, improving the aeration and regeneration effect and rate.

[0043] By incorporating ultraviolet lamps and spiral plates, wastewater with low suspended solids enters the photocatalytic cylinder after being treated by the separator. Within the photocatalytic cylinder, the spiral plates act as separators, ensuring the wastewater receives more comprehensive irradiation from the ultraviolet lamps located at the center. Simultaneously, aeration is achieved through external aeration rings, enhancing the photocatalytic effect and rate. During aeration, a switching between coarse and fine pores is employed. Initially, fine pores are used for aeration, generating high gas velocity and turbulence to disrupt liquid film resistance and promote gas diffusion into the liquid phase. Later, coarse pores are used for aeration, with low gas velocity forming stable bubbles, extending gas-liquid contact time and improving overall aeration efficiency. Attached Figure Description

The turbulence driven gear 125 is rotatably mounted on the stirring rod 123 adjacent to the annular inner sleeve 124. The turbulence driven gear 125 meshes with the turbulence inner gear disk 126 and is connected to the turbulence disk 127.

[0089] The working principle of this embodiment is as follows:

[0090] The saline wastewater generated during glyphosate production first enters the pretreatment tank 1 through the inlet pipe 11. In the pretreatment tank 1, a pH sensor 137 located at the inlet of the outlet pipe 12 detects the pH value of the wastewater. When the detected pH value differs from the preset range, a signal is sent to the controller. Upon receiving the signal, the controller activates the pump in the corresponding pH adjustment solution tank 117. The two pH adjustment solution tanks 117 contain alkaline and acidic solutions respectively. Based on the actual pH value, the pump in the corresponding pH adjustment solution tank 117 is activated, and the corresponding solution is finally transported to the corresponding adjustment tank 16. The extrusion block 112 in the adjustment tank 16 is in its initial state. Position 2 is located above the solution inside the regulating tank 16. When the first drive motor 13 is started and rotates forward, it drives the regulating drive gear 14 to rotate. The regulating drive gear 14 drives the regulating external gear disk 15 to rotate. The rotation of the regulating external gear disk 15 drives the two regulating driven gears 17 to rotate. Since both regulating driven gears 17 are connected to their respective reciprocating lead screws 111 via their corresponding first one-way shafts 110, and the two first one-way shafts 110 are set in different directions, when the first drive motor 13 rotates forward, it will only drive one of the reciprocating lead screws 111 to rotate. The two reciprocating lead screws 111 correspond to different regulating tanks 16, and the two regulating tanks 16 are used to hold acidic and alkaline solutions respectively. Therefore, the forward and reverse rotation of the first drive motor 13 is required to rotate the solution. The addition of a specific solution is controlled by adjusting the actual pH value and using a controller. When the reciprocating screw 111 is driven to rotate, the extrusion block 112, mounted outside the screw and initially positioned, moves, extruding the solution in the extrusion chamber 18. The extrusion block 112 abuts against the inner wall of the regulating tank 16, preventing leakage through the gap during extrusion. Simultaneously, the regulating tank 16 restricts the extrusion block 112, preventing it from rotating under the influence of the reciprocating screw 111. The extrusion block 112 and the reciprocating screw 111 are assembled using ball bearing nuts. The specific working principle is based on existing technology and will not be detailed here. The downward-moving extrusion block 112 forces the solution from... The solution is squeezed from the squeezing chamber 18 into the spraying chamber 19. The spraying chamber 19 has a smaller space than the squeezing chamber 18. The squeezed solution in the spraying chamber 19 exerts a pushing force on the sealing part 115 of the sealing plate 114 at the outlet end of the regulating tank 16, thereby stretching the spring telescopic rod 113. The sealing plate 114, under this pushing force, loses its sealing effect at the outlet end, and the solution is discharged from the outlet end. During the discharge process, it comes into contact with the arc-shaped guide part 116. Under the action of the guide part 116, the solution is sprayed out at an arc angle, allowing the solution to mix with the wastewater more quickly, thus achieving the effect of adjusting the pH value. Furthermore, since the outlet end of the regulating tank 16 is located inside the wastewater, the mixing effect between the solution and the wastewater is further improved, resulting in a faster overall pH adjustment rate.After the solution extrusion and spraying is completed, the continuously rotating reciprocating screw 111 drives the extrusion block 112 to reset. During the reset, the sealing plate 114 loses the thrust from the solution. Simultaneously, through the retraction and reset effect of the spring telescopic rod 113, the sealing part 115 re-seals the outlet end, preventing the extrusion block 112 from generating negative pressure during reset and drawing wastewater into the regulating tank 16. It should be noted that the positions of the two pH value regulating solution tanks 117 can be adjusted according to the actual situation and the selected components for transporting the solution to the corresponding regulating tank 16. The positions in the figure are only for illustration. The unidirectional shaft can also be replaced with a ratchet shaft depending on the actual situation, as long as the above-mentioned specific effects are achieved. The pH sensor 137 is existing technology, and its working principle will not be described in detail here. The wire connected to the pH sensor 137 passes through the pretreatment cylinder 1, and a seal is applied between the two.

[0091] Throughout the pH adjustment process, the stirring rod 123 can be used for auxiliary stirring. When stirring is required, the second drive motor 118 is started to rotate forward, driving the stirring drive gear 119 to rotate. The stirring drive gear 119 drives the stirring driven gear 120 to rotate, and the stirring driven gear 120 drives the drive sleeve 121 to rotate. The rotation of the drive sleeve 121 drives the connecting plate 122 and the stirring rod 123 to rotate continuously. The continuously rotating stirring rod 123 can increase the mixing rate of the solution and wastewater.

[0092] After pH adjustment, the coagulant in the coagulant tank 135 needs to be added to the wastewater to react with the wastewater and remove some impurities. After the pH of the wastewater is adjusted to the preset range, the controller starts the delivery pump in the coagulant tank 135, which delivers the coagulant through the feed port 134 to the sedimentation inner sleeve 132. Finally, the coagulant falls into the second channel 133 through the feed port 134. At this time, the sedimentation inner sleeve 132 is in the initial state, and the second channel 133 is not connected to the first channel 130 of the sedimentation outer sleeve 129. Therefore, the coagulant in the second channel 133 will not come into contact with the wastewater. When the second drive motor 118 reverses, the reverse drive sleeve 121 drives the second one-way shaft 131 and the sedimentation inner sleeve. Rotation of 132 causes an angular shift, sufficient to connect the second channel 133 with the first channel 130. When connected, wastewater and coagulant mix. It should be noted that the second drive motor 118 rotates forward only when it needs to accelerate mixing by driving the stirring rod 123; it rotates in reverse when coagulant needs to be added. During forward rotation, the drive sleeve 121 cannot drive the second one-way shaft 131 to rotate. During reverse rotation, it not only drives the sedimentation inner sleeve 132 to add coagulant to the wastewater by rotation, but also continues to drive the stirring rod 123 to accelerate the mixing of coagulant and wastewater. After addition is complete, the drive sleeve 121 continues to rotate in reverse, causing the first channel 130 and the second channel 133 to become interleaved, stopping the coagulant flow. Adding coagulant involves adjusting the angle of the sedimentation inner sleeve 132, which in turn affects the position of the feed port 134. When the second channel 133 is connected to the first channel 130, the feed port 134 is disconnected from the delivery pipe of the coagulant tank 135. When the first channel 130 and the second channel 133 are disconnected again, the feed port 134 connects to the delivery pipe of the coagulant tank 135, allowing coagulant to be added to the second channel 133. Furthermore, the delivery pump in the coagulant tank 135 can be controlled via a controller. Each wastewater treatment cycle involves only one addition of coagulant, meaning that when the sedimentation inner sleeve 132 is not rotating and the two channels are disconnected, coagulant is added through the feed port 134 into the second channel 133. Subsequent additions are made regardless of whether the sedimentation inner sleeve 132 is rotating or not. Rotation ceases coagulant delivery until wastewater treatment is complete. At this point, the first channel 130 and the second channel 133 are connected to drain excess coagulant and wastewater that entered the second channel 133 during the connection process. The sedimentation inner sleeve 132 is then reset for a new round of wastewater treatment. This ensures that coagulant is added quantitatively each time wastewater is treated. It should be noted that the second one-way shaft 131 can also be replaced with a ratchet shaft to achieve the same effect. The bottom of the sedimentation outer sleeve 129 is fixed, but the top is connected to the drive sleeve 121 via a rotating shaft. Therefore, regardless of how the drive sleeve 121 rotates, the positions of the sedimentation outer sleeve 129 and the first channel 130 remain fixed.The final flocculent formed by the reaction of the coagulant with impurities in the wastewater will settle below the first filter screen 136. The position of the coagulant tank 135 in the diagram is for illustrative purposes only and can be changed according to actual conditions. The coagulant can be transported via a built-in pump through a delivery pipe, or the coagulant tank 135 can be positioned directly above the pretreatment cylinder 1 and transported by its own weight. The specific choice can be made according to actual needs.

[0093] In the above process, the main mixing method is achieved by the rotation of the stirring rod 123. However, the stirring rod 123 rotates around the center of the driving sleeve 121 under the drive of the driving sleeve 121, which is relatively simple. In order to further improve the mixing effect, an annular inner sleeve 124 is provided inside the pretreatment cylinder 1. A turbulence-inner gear disk 126 is provided on the annular inner sleeve 124. The function of the annular inner sleeve 124 is to support the turbulence-inner gear disk 126. A turbulence-driven gear 125 is rotatably provided on the stirring rod 123 adjacent to the turbulence-inner gear disk 126. The turbulence driven gear 125 meshes with the turbulence inner gear disk 126. When the stirring rod 123 rotates, it drives the turbulence driven gear 125 to move. The turbulence driven gear 125 rotates under the drive of the turbulence inner gear disk 126. The rotation of the turbulence driven gear 125 drives the rotation of the turbulence disk 127. The rotation direction of the turbulence disk 127 is different from the rotation direction of the stirring rod 123, so it can play a turbulence effect. The turbulence generated by the turbulence disk 127 further enhances the mixing of coagulant and wastewater or the mixing of pH adjustment solution and wastewater.

[0094] The above describes the pretreatment of wastewater. During the long-term operation of the pretreatment cylinder 1, excessive sediment produced by the reaction of coagulant and wastewater accumulates at the bottom of the first filter screen 136, affecting the normal pretreatment process. Therefore, it is necessary to rinse the pretreatment cylinder 1. A water turbidity sensor 7 is installed on the pretreatment cylinder 1, located below the first filter screen 136. When the water turbidity sensor detects that the water below the first filter screen 136 is turbid beyond the threshold, it means that too much sediment has been produced. At this time, the entire interior of the pretreatment cylinder 1 can be cleaned by introducing a cleaning solution through the inlet pipe 11. The cleaned water is discharged through the first flushing outlet pipe 71 at the bottom of the pretreatment cylinder 1. The water turbidity sensor 7 is existing technology, and its working principle will not be described in detail here. The wire connected to the water turbidity sensor 7 passes through the pretreatment cylinder 1, and the two are sealed.

[0095] Example 2: Figure 9-11As shown, this embodiment further includes the following structure based on embodiment one: the filter adsorption assembly includes a rotating mechanism, a rotating sleeve 21, and a storage mesh cylinder 211 disposed inside the rotating sleeve 21. The storage mesh cylinder 211 is provided with biological activated carbon. The filter cylinder 2 is provided with a partition 22. The partition 22 is in contact with the rotating sleeve 21, and a sealing gasket is provided at the contact part. A regeneration chamber 23 is formed between the partition 22 and the inner wall of the filter cylinder 2. A regeneration hole 212 is opened in the regeneration chamber 23. The regeneration hole 212 is suitable for introducing oxidant. A filter chamber 214 is formed between the partition 22 and the central part of the filter cylinder 2. The rotating sleeve 21 is partially open. When the open part is located in the filter chamber 214, the storage mesh cylinder 211 is in contact with wastewater. When the open part is located in the regeneration chamber 23, the storage mesh cylinder 211 is in contact with oxidant. The rotating mechanism is partially connected to the rotating sleeve 21 to drive the rotating sleeve 21 to rotate, thereby changing the opening position.

[0096] The rotating mechanism includes a third drive motor 24, a filter drive gear 25, driven inner and outer gear discs 26, a third one-way shaft 29, a filter inner gear disc 210, and a second driven inner gear 213 corresponding to the rotating sleeve 21. The filter drive gear 25, the filter inner gear disc 210, and the second driven inner gear 213 are all rotatably mounted on the filter cylinder 2. The driven inner and outer gear discs 26 are located above the filter inner gear disc 210. The third one-way shaft 29 connects to the driven inner and outer gear discs 26 and the filter inner gear disc 210. The third drive motor 24 is mounted on the filter cylinder 2. The third drive motor 24 and the filter drive gear 25 are connected to the filter inner gear disc 210. The gears 25 are connected to drive the filter drive gear 25 to rotate. The filter drive gear 25 meshes with the outer teeth of the driven inner and outer gear disks 26. The second driven inner gear 213 meshes with the filter inner gear disk 210. The second driven inner gear 213 is connected to the rotating sleeve 21. The filter drive gear 25 is adapted to be driven to rotate forward, thereby driving the driven inner and outer gear disks 26, the filter inner gear disk 210, the second driven inner gear 213, and the rotating sleeve 21 to rotate synchronously, thereby changing the opening position of the rotating sleeve 21. When the filter drive gear 25 is driven to rotate in reverse, it only drives the driven inner and outer gear disks 26 to rotate.

[0097] like Figure 10-11 As shown, a rotating rod 28 is rotatably installed inside the rotating sleeve 21. The upper end of the rotating rod 28 passes through the rotating sleeve 21, the filter cylinder 2, and the second driven internal gear 213. The storage screen cylinder 211 is fixedly sleeved on the outside of the rotating rod 28. The upper end of the rotating rod 28 is connected to the first driven internal gear 27. The first driven internal gear 27 meshes with the internal teeth of the driven inner and outer gear disk 26. When the filter drive gear 25 is driven to reverse, it drives the driven inner and outer gear disk 26, the first driven internal gear 27, the rotating rod 28, and the storage screen cylinder 211 to rotate.

[0098] The working principle of this embodiment is as follows:

[0099] After pretreatment, the wastewater is discharged through the outlet pipe 12 on the pretreatment cylinder 1 and then enters the filter cylinder 2. A rotating sleeve 21 is installed inside the filter cylinder 2, and a storage mesh cylinder 211 is installed inside the rotating sleeve 21. Activated biochar is placed inside the storage mesh cylinder 211. An opening is provided on the rotating sleeve 21 to expose the storage mesh cylinder 211. A baffle 22 is also installed inside the filter cylinder 2, which is in contact with the entire rotating sleeve 21. Sealing gaskets are placed at the contact points, ensuring a seal between the baffle 22 and the outer surface of the rotating sleeve 21. The internal space of the entire filter cylinder 2 is divided into a filter chamber 214 and a regeneration chamber 23. The filter chamber 214 is the space between the partition 22 and the center of the filter cylinder 2, and the regeneration chamber 23 is the space between the partition 22 and the inner wall of the filter cylinder 2. The pretreated wastewater enters the filter chamber 214 in the filter cylinder 2 through the outlet pipe 12. In the filter chamber 214, it comes into contact with the biological activated carbon in the storage mesh cylinder 211. The biological activated carbon plays an adsorption role on the impurities in the wastewater. After the adsorption is completed, the treated wastewater is then passed from the bottom of the filter cylinder 2 into the separator 3.

[0100] When wastewater is introduced into the separatory cylinder 3 after adsorption treatment by the biological activated carbon in the storage mesh cylinder 211, the filter cylinder 2 is empty of wastewater. At this time, the third drive motor 24 is started and rotates forward, driving the filter drive gear 25 to rotate. The filter drive gear 25 drives the driven inner and outer gear discs 26 to rotate. The driven inner and outer gear discs 26 drive the third one-way shaft 29 and the filter inner gear disc 210 to rotate. The filter inner gear disc 210 drives the second driven inner gear 213 to rotate. The second driven inner gear 213 drives the rotating sleeve 21 to rotate until the opening is located in the regeneration chamber 23. The rotating sleeve 21 is designed to be rotatable, which does not affect the sealing effect between the partition 22 and the rotating sleeve 21. However, repeated rotation will cause friction and compression of the sealing gasket, which will damage the sealing gasket and need to be replaced regularly. When the opening of the rotating sleeve 21 is located in the regeneration chamber 23, pure oxygen, ozone and other gases are introduced through the regeneration hole 212 to contact the biological activated carbon in the storage mesh cylinder 211, thereby quickly decomposing the organic matter adsorbed on the biological activated carbon, thus achieving the effect of biological activated carbon regeneration, so as to ensure that each adsorption and filtration treatment can be effectively completed.

[0101] To further increase the contact area between the storage screen cylinder 211 and wastewater when the opening of the rotating sleeve 21 faces the filter chamber 214, and the contact area with gases such as ozone when the opening of the rotating sleeve 21 faces the regeneration chamber 23, the storage screen cylinder 211 is configured to rotate within the rotating sleeve 21. Specifically, a rotating rod 28 is installed inside the rotating sleeve 21, and the storage screen cylinder 211 is sleeved on the rotating rod 28. One end of the rotating rod 28 passes through the rotating sleeve 21, the filter cylinder 2, and the second driven internal gear 213, and extends to the outside of the second driven internal gear 213. A first driven internal gear 27 is connected to the extended part, and the first driven internal gear 27 meshes with the internal teeth of the driven internal and external gear disc 26. The first driven internal gear 27 is used to achieve the position change of the rotating sleeve 21. With the third drive motor 24 rotating forward, only the rotating rod 28 needs to be driven to rotate, allowing the storage screen 211 to rotate within the rotating sleeve 21. At this point, the third drive motor 24 needs to be started in reverse. In reverse, only the filter drive gear 25 and the driven inner and outer gear discs 26 rotate. Due to the restriction of the third one-way shaft 29, the second driven inner gear 213 and the filter inner gear disc 210 will not rotate, meaning the rotating sleeve 21 will not rotate. However, the driven inner and outer gear discs 26 will drive the first driven inner gear 27 to rotate, thus rotating the rotating rod 28 and achieving the effect of rotating the storage screen 211 within the rotating sleeve 21. By reversing the third drive motor 24, the independent rotation of the storage screen 211 can be controlled. 4. The rotation of the rotating sleeve 21 can cause the opening of the rotating sleeve 21 to be in either the filter chamber 214 or the regeneration chamber 23. Adjusting the position of the rotating sleeve 21 will allow the storage mesh cylinder 211 to continue rotating without changing its position. This allows the storage mesh cylinder 211 and the bio-activated carbon inside it to increase their contact area with wastewater or gases such as ozone through rotation, regardless of the position of the rotating sleeve 21. During rotation, the bio-activated carbon inside the storage mesh cylinder 211 will move under centrifugal force, and the portion of the rotating sleeve 21 that is not in the opening position will continuously switch to the opening position during rotation. It should be noted that in the regeneration chamber 23, besides introducing gases such as ozone through the regeneration hole 212, the bio-activated carbon... Besides regeneration, other methods can also be used. For example, an ultraviolet lamp can be installed inside the regeneration chamber 23, or the material of the filter cartridge 2 can be made of transparent material, allowing an ultraviolet lamp to be installed outside the filter cartridge 2 to achieve the regeneration effect through ultraviolet irradiation. Alternatively, a regeneration method can be achieved by introducing hot air currents such as steam through the regeneration hole 212 to heat the bio-activated carbon. Regeneration by heating requires improving the high-temperature resistance of components such as the filter cartridge 2, rotating sleeve 21, and partition 22. A rotary seal can be installed between the rotating sleeve 21 and the filter cartridge 2 to prevent water from overflowing from the filter cartridge 2. A rotary seal can also be installed between the rotating rod 28 and the rotating sleeve 21 to prevent water from overflowing. Alternatively, controlling the amount of water entering the filter cartridge 2 each time can also prevent the problem of water overflowing from the filter cartridge 2.The third one-way shaft 29 can also be replaced with a ratchet shaft depending on the actual situation, as long as the above effect is achieved.

[0102] Example 3: Figure 12-15 , Figure 18 As shown, this embodiment further includes the following structure based on embodiment one: a baffle 31 is provided inside the liquid separator 3, the baffle 31 is located above the second filter screen 32, the second filter screen 32 is inclined, and a water inlet is provided on the baffle 31 that passes through itself. The position of the water inlet corresponds to the high point of the inclined second filter screen 32. The second filter screen 32 is suitable for filtering the wastewater into high suspended solids wastewater and then passing it into the electrocatalytic cylinder 5 through the first liquid separator. The third filter screen 33 is suitable for filtering the wastewater into low suspended solids wastewater and then passing it into the photocatalytic cylinder 4 through the second liquid separator.

[0103] A quartz glass tube sleeve 42 is provided at the center of the photocatalytic cylinder 4. An ultraviolet lamp 41 is inserted into the quartz glass tube sleeve 42. A spiral plate 43 is provided on the outer surface of the quartz glass tube sleeve 42 inside the photocatalytic cylinder 4. The spiral plate 43 is suitable for dividing the wastewater entering the photocatalytic cylinder 4. An aeration sleeve 44 is provided on the outside of the photocatalytic cylinder 4. At least one addition port 45 is provided on the aeration sleeve 44. A number of aeration rings are arranged at intervals on the part of the photocatalytic cylinder 4 covered by the aeration sleeve 44. The aeration rings are distributed in several rings and penetrate the aeration holes of the photocatalytic cylinder 4. Each group of aeration rings is located between two adjacent spirals of the spiral plate 43.

[0104] The electrocatalytic cartridge 5 is arranged in a ring shape, and several electrode plates 51 are arranged in a ring inside the electrocatalytic cartridge 5. The power interface part of the electrode plate 51 is located outside the electrocatalytic cartridge 5.

[0105] like Figure 16-17 As shown, the aeration holes are divided into coarse holes 46 and fine holes 47. The aeration sleeve 44 is provided with several switching rings and switching mechanisms corresponding to each group of aeration rings. The switching rings are rotatably set outside the photocatalytic cylinder 4. The switching rings are suitable for blocking the coarse holes 46 and / or fine holes 47. The switching mechanism is connected to the switching rings to change the blocking state of the switching rings.

[0106] The switching ring includes a switching plate 48 corresponding to a plurality of aeration holes and a docking ring 49, the docking ring 49 being adapted to dock the plurality of switching plates 48.

[0107] The switching mechanism includes a fourth drive motor 413, a switching drive gear 412, a switching outer gear disc 411, and a linkage rod 410. The fourth drive motor 413 is mounted on the aeration sleeve 44. The switching drive gear 412 and the switching outer gear disc 411 are both rotatably mounted inside the aeration sleeve 44. The switching drive gear 412 and the switching outer gear disc 411 mesh with each other. The fourth drive motor 413 is connected to the switching drive gear 412 to drive the switching drive gear 412 to rotate. The linkage rod 410 is connected to the switching outer gear disc 411. The linkage rod 410 passes through and is nested inside the switching plate 48 in all the switching rings. The switching outer gear disc 411 is adapted to be driven to rotate, thereby causing the linkage rod 410 and all the switching rings to shift in angle.

[0108] The working principle of this embodiment is as follows:

[0109] After being adsorbed and filtered by the biological activated carbon in filter cylinder 2, the wastewater enters the separator cylinder 3 from the bottom of filter cylinder 2. A baffle 31 with an outlet in the separator cylinder 3 partially obstructs the wastewater, forcing it to flow through the outlet to the high point of the second filter screen 32. At this high point, the wastewater undergoes primary filtration. Impurities filtered out at the high point of the second filter screen 32 accumulate and slide down to the low point, eventually falling into the accumulation tank 8. The wastewater passing through the second filter screen 32 then undergoes secondary filtration through the third filter screen 33. When the first and second separator ports are closed, the two filtrations cause the wastewater at the separator cylinder 33 to undergo further filtration. The wastewater inside cylinder 3 exists in two states. The wastewater located below the second filter screen 32 and above the third filter screen 33 is filtered only by the second filter screen 32 and not by the third filter screen 33, thus it is high-suspended-solids wastewater. The wastewater located below the third filter screen 33 is filtered by both the second and third filters, thus it is low-suspended-solids wastewater. The amount of wastewater entering the separatory cylinder 3 each time is controlled so that the total amount of water just submerges the second filter screen 32. The remaining wastewater temporarily remains in the filter cylinder 2. Once all the measured amount of wastewater has entered the separatory cylinder 3, the first separatory port can be opened first to allow the high-suspended-solids wastewater between the second and third filters 32 to pass through. Inside the electrocatalytic cartridge 5, the second separator is opened to allow the low-suspended-solids wastewater located below the third filter screen 33 to flow into the photocatalytic cartridge 4. This separation method reduces the frequency of filter plate replacement or cleaning while ensuring the quality and efficiency of wastewater treatment through two different catalytic methods. After a fixed amount of wastewater is separated into the electrocatalytic cartridge 5 and the photocatalytic cartridge 4 in the separator 3, the filter cartridge 2 then flows a fixed amount of wastewater into the separator 3. This process is repeated until all the wastewater in the filter cartridge 2 is emptied. It should be noted that after the dual treatment by the pretreatment cartridge 1 and the filter cartridge 2, although the wastewater is referred to as high-suspended-solids wastewater and low-suspended-solids wastewater, the suspended solids content of both is actually controlled within a certain range. For lower levels, the distinction between high and low suspended solids is made only by comparing the two, so it will not cause excessive pressure on the second filter 32, the third filter 33, the electrocatalytic cylinder 5, and the photocatalytic cylinder 4 when treating wastewater. Over time, the sedimentation tank 8 of the separator 3 accumulates more and more impurities, which can be monitored by the operator through the transparent observation window 81. When there are too many impurities in the sedimentation tank 8, the separator 3 needs to be backwashed regularly. The backwashing method is to pass a cleaning solution into the backwash inlet pipe 82, and then discharge the used rinsing solution and the impurities carried out through the second backwash outlet pipe 83 to ensure that all components in the separator 3 can work normally.

[0110] After separation, the wastewater entering the electrocatalytic cylinder 5 will remain inside the annular electrocatalytic cylinder 5 for electrocatalytic treatment. Specifically, the electrode plates 51 arranged in annular intervals inside the electrocatalytic cylinder 5 are energized, and the wastewater is treated after being energized. The annularly arranged electrode plates 51 are divided into cathodes and anodes arranged alternately. The energized part of the electrode plate 51 is located outside the electrocatalytic cylinder 5. The specific principle of the electrode plate 51 treating the wastewater is existing technology and will not be described in detail here. The annular setting of the electrocatalytic cylinder 5 is to increase the contact area between the wastewater and the electrode plate 51, reduce the size of the electrode plate 51, and save costs.

[0111] After separation, the wastewater entering the photocatalytic cylinder 4 will fill the entire interior of the photocatalytic cylinder 4 in a spiral pattern under the obstruction of the spiral plate 43. The obstruction of the spiral plate 43 slows down the rate at which the wastewater fills the photocatalytic cylinder 4, and the contact time with the ultraviolet lamp 41 located in the center is longer. The position of the photocatalytic cylinder 4 for inserting the ultraviolet lamp 41 is set as a quartz glass tube sleeve 42. The ultraviolet lamp 41 is inserted into the quartz glass tube sleeve 42, which facilitates the disassembly or installation of the ultraviolet lamp 41. The material of the quartz glass tube sleeve 42 can ensure that the ultraviolet light can effectively penetrate and irradiate the wastewater inside the photocatalytic cylinder 4. A ring of aeration holes is set between the two spirals of the spiral plate 43. An aeration sleeve 44 covering all the aeration holes is set on the outside of the photocatalytic cylinder 4. The aeration sleeve 44 has an addition port 45. The addition port 45 can be used to introduce gases such as ozone and pure oxygen, or photocatalyst. The gas introduced later promotes the photocatalyst to enter the photocatalytic cylinder 4 through the aeration holes.

[0112] The single aeration hole can also be divided into two types: coarse holes 46 and fine holes 47. A switching ring is rotatably installed between the two spirals of the threaded plate on the outside of the photocatalytic cylinder 4. The switching ring includes spaced-apart switching plates 48. Each switching plate 48 can completely block a set of coarse holes 46 and fine holes 47. All switching plates 48 are connected via docking rings 49. By controlling the rotation of the entire switching ring, four main states can be achieved: complete blocking of coarse holes 46 and fine holes 47; blocking only coarse holes 46; blocking only fine holes 47; and simultaneously opening both coarse holes 46 and fine holes 47. Complete blocking means the photocatalytic cylinder 4 is not in operation; no photocatalyst needs to be added, and no aeration is required. Blocking only coarse holes 46 means only opening fine holes 47; gas enters the fine holes 47 through the aeration sleeve 44 and then enters the photocatalytic cylinder. Because of the small diameter of the fine pores 47 in the catalytic cylinder 4, the gas entering the catalytic cylinder 4 is subjected to greater compression, resulting in a faster gas flow rate and a greater impact on the wastewater inside the catalytic cylinder 4. This promotes gas-liquid mixing, and the high gas velocity generates turbulence, which breaks down the liquid film resistance and promotes gas diffusion into the liquid phase. Separating the fine pores 47 means that only the coarse pores 46 are open. The low gas velocity through the coarse pores 46 forms stable bubbles, prolonging the gas-liquid contact time and improving the overall aeration effect. The simultaneous opening of the coarse pores 46 and the fine pores 47 can be used when cleaning of the coarse pores 46 and the fine pores 47 is required. The specific state can be adjusted according to the actual situation. Alternatively, the switching ring can be rotated to open only some of the coarse pores 46 or some of the fine pores 47, etc., making the overall use flexible.

[0113] The specific method for driving the overall rotation of the switching rings is as follows: First, all the switching rings located in the aeration sleeve 44 are connected in series by the linkage rod 410. Specifically, the linkage rod 410 passes through and is nested in the switching plate 48. Since the switching plates 48 are connected by the docking ring 49, it passes through the inside of the docking ring 49 while passing through the switching plate 48. After all the switching rings are connected in series, one end of the linkage rod 410 is connected to the switching outer gear disc 411. The switching outer gear disc 411 is rotatably set in the aeration sleeve 44. The fourth drive motor 413 is started to drive the switching drive gear 412 to rotate. The switching drive gear 412 drives the switching outer gear disc 411 to rotate, so that all the linkage rods 410 can rotate around the switching outer gear disc 411 as the center. When the linkage rod 410 rotates, the effect of the switching ring rotation switching state can be achieved. The switching outer gear disc 411, photocatalytic cylinder 4, aeration sleeve 44, and switching rings are all coaxially set.

[0114] A titanium oxide coating 415 is disposed on the surface of the spiral plate 43 near the ultraviolet lamp 41, and a silver reflective coating 414 is disposed on the surface of the spiral plate 43 away from the ultraviolet lamp 41. The titanium oxide coating 415 generates electrons under ultraviolet excitation, producing hydroxyl radicals and superoxide radicals, which directly degrade glyphosate molecules adsorbed on the surface of the spiral plate 43. The specific principle is existing technology and will not be elaborated further here. The proximity of the titanium oxide coating 415 to the light source ensures sufficient catalysis in the high-intensity area, avoiding light energy waste. The silver reflective coating 414... Ultraviolet rays far from the light source area are reflected back to the reaction area, improving the optical path utilization rate. The silver reflective coating 414 on both sides of the spiral plate 43 forms a "U-shaped reflective cavity". After multiple reflections in the cavity, the ultraviolet rays are reflected by the titanium oxide coating 415, improving the overall light energy utilization rate. The design of regional coatings improves the light energy utilization rate and achieves a synergistic effect. The coating process of the titanium oxide coating 415 can be magnetron sputtering, and the coating process of the silver reflective coating 414 can be electron beam evaporation. The specific settings of the corresponding coatings are existing technologies and will not be described in detail here.

[0115] After all the wastewater in the electrocatalytic cylinder 5 and the photocatalytic cylinder 4 is treated, it will eventually be collected in the evaporation crystallization cylinder 6. The evaporation crystallization cylinder 6 includes a heating system, an evaporation chamber and a crystallization chamber, a separation device, anti-scaling components, condensation and exhaust components, and a control system. After the wastewater from electrocatalysis and photocatalysis is collected in the evaporation crystallization cylinder 6, the automatic stirring device in the evaporation crystallization cylinder 6 will first mix the wastewater, and then carry out subsequent heating and crystallization treatment. Finally, the salt and recalcitrant organic matter in the wastewater will be concentrated and crystallized. The separated solids can be recycled or safely disposed of, and the condensate can meet the reuse or discharge standards, thus reducing the environmental burden. The entire evaporation crystallization cylinder 6 is based on existing technology, and its specific working principle will not be described in detail here.

[0116] This invention also provides a process for treating wastewater from glyphosate production, comprising the following steps:

[0117] S1. Wastewater enters the pretreatment cylinder 1 through the inlet pipe 11. In the pretreatment cylinder 1, the pH value of the wastewater is adjusted to neutral or weakly alkaline by the pH adjustment component. Then, the coagulant is mixed with the wastewater by the coagulant addition component, which promotes the formation of flocs from suspended solids, colloids and some organic matter in the wastewater, thereby reducing the load on subsequent treatment.

[0118] S2. Wastewater in filter cartridge 2 is filtered by adsorption and filtration components to remove residual organic matter, heavy metal ions and fine particles.

[0119] S3. Wastewater that passes only through the second filter screen 32 when passing through the separator 3 is high suspended solids wastewater and enters the electrocatalytic cylinder 5 through the first separator for treatment. Wastewater that passes through both the second filter screen 32 and the third filter screen 33 at the same time is low suspended solids wastewater and enters the photocatalytic cylinder 4 through the second separator for treatment.

[0120] S4. Wastewater treated by photocatalytic cylinder 4 or electrocatalytic cylinder 5 is collected in evaporation crystallization cylinder 6 for evaporation to remove moisture and concentrate salt.

[0121] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
