Description

Technical Field

[0001] This invention belongs to the field of microbial reactor technology, and more specifically, relates to a microbial enhanced reactor for water treatment. Background Technology

[0002] In the field of water treatment, microbial degradation technology is widely used in the treatment of pollutants in wastewater due to its advantages such as being environmentally friendly, efficient, and free from secondary pollution. Among these advantages, the proper use of microbial immobilization carriers is key to improving treatment effectiveness.

[0003] Currently, in practical applications, existing microbial enhanced reactors have been found to have the following problems: the addition methods of slurries such as HPB composite powder carriers are relatively simple, but the central stirring has a stirring blind zone. The slurry near the center of the reaction tank is difficult to be fully stirred, which further aggravates the problem of uneven slurry distribution. This leads to uneven degradation of pollutants by microorganisms, unstable treatment effect, and a large amount of slurry easily remains on the inner wall of the slurry tank. This residual slurry cannot participate in the microbial fixation and pollutant degradation reaction, which not only wastes slurry but also increases operating costs.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example

[0021] like Figures 1 to 8 As shown, a microbial enhancement reactor for water treatment includes a reaction tank 1.

[0022] A packing frame 172 is rotatably mounted on the reaction vessel 1, and a drive motor 17 is mounted above the reaction vessel 1, and the drive motor 17 is used to drive the packing frame 172 to rotate. A conveying pipe 2 is rotatably mounted at the bottom of the packing frame 172. A support frame 23 is slidably mounted on the side wall of the conveying pipe 2, and one end of the support frame 23 slides in a guide groove 243 opened on the inner side wall of the reaction tank 1. The guide groove 243 is quincunx-shaped. During the rotation of the packing frame 172, the conveying pipe 2 is driven to swing back and forth through the guide groove 243, changing the feeding position. An adjusting plug 22 is inserted into the inlet of the conveying pipe 2. The adjusting plug 22 is conical, and the top of the adjusting plug 22 is slidably connected to the guide slope 223 installed on the side wall of the packing frame 172. The conveying pipe 2 rotates through the guide slope 223. During the process, the regulating plug 22 moves at the inlet of the conveying pipe 2, changing the flow rate of the conveying pipe 2. As the conveying pipe 2 deflects toward the center of the reaction tank 1, the flow rate of the conveying pipe 2 decreases synchronously. A storage cover 32 is installed on the reaction tank 1, and a piston 323 is slidably installed on the storage cover 32. The drive motor 17 drives the piston 323 to slide vertically. When the piston 323 moves upward, it drives the liquid in the reaction tank 1 to flow toward the storage cover 32. When the piston 323 moves downward, the liquid is transported to the side wall of the packing frame 172, flushing the slurry remaining on the side wall of the packing frame 172.

[0023] The drive motor 17 drives the packing frame 172 to rotate, and the plum blossom-shaped guide groove 243 drives the conveying pipe 2 to swing back and forth, so that the feeding position can be adjusted. At the same time, the conveying flow rate can be adaptively adjusted by the cooperation of the adjusting plug 22 and the guide slope 223. Combined with the storage cover 32 and the piston 323, the side wall of the packing frame 172 is flushed, which effectively solves the problems of uneven feeding and slurry residue in the existing equipment and improves the practicality of the equipment.

[0024] like Figures 1 to 8 As shown in the specific embodiment, a frame 11 is installed at the bottom of the reaction vessel 1, and support legs 111 are installed around the frame 11. Anti-slip grooves are installed at the bottom of the support legs 111, and a base plate 112 is installed on the support legs 111. The base plate 112 is welded to the side wall of the reaction vessel 1, and an observation window 113 is installed on the reaction vessel 1. The frame 11, support legs 111, and base plate 112 cooperate with each other to stably support the reaction vessel 1. The anti-slip grooves at the bottom of the support legs 111 improve the stability of the equipment placement, and the observation window 113 allows operators to observe the internal reaction of the reaction vessel 1 in real time, reducing the difficulty of operation.

[0025] like Figures 1 to 8As shown, further, a water inlet pipe 12 is installed at one end of the reaction tank 1, and a water outlet pipe 13 is installed at the other end. Valves are installed on the water inlet pipe 12 and the water outlet pipe 13, and connecting flanges 14 are installed at the ends of the water inlet pipe 12 and the water outlet pipe 13. A connecting frame 151 is installed on the side wall of the reaction tank 1, and a controller 15 is installed on the connecting frame 151. The controller 15 is used to control the rotation of the drive motor 17. The water inlet pipe 12 and the water outlet pipe 13 respectively realize the introduction of water to be treated and the discharge of treated water. The valves can flexibly control the water flow. The connecting flange 14 facilitates the connection of the water inlet pipe 12 and the water outlet pipe 13 with external pipelines. The controller 15 fixed on the connecting frame 151 can accurately control the rotation of the drive motor 17, realize the automated control of the equipment, and improve the ease of operation.

[0026] like Figures 1 to 8 As shown, a protective cover 16 is further installed on the top of the reaction vessel 1, and a cover plate 161 is installed on the protective cover 16. Opening the cover plate 161 allows slurry to be poured into the packing frame 172. The outer wall of the protective cover 16 is connected to the drive motor 17, and the output end of the drive motor 17 passes through the protective cover 16. An arched frame 171 is installed on the output rod of the drive motor 17, and the arched frame 171 is connected to the outer wall of the packing frame 172. The protective cover 16 can protect the internal structures such as the packing frame 172 and the output end of the drive motor 17. The cover plate 161 facilitates the pouring of slurry into the packing frame 172, and the arched frame 171 can stably transmit the power of the drive motor 17, driving the packing frame 172 to rotate smoothly and ensuring stable operation of the equipment. Example

[0027] The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, a connecting shaft 21 is installed at the end of the conveying pipe 2, and the end of the connecting shaft 21 is connected to the outer wall of the packing frame 172. A strip plate 232 is installed at the bottom of the conveying pipe 2, and a strip groove 233 is opened on the strip plate 232. A sliding rod 231 is slidably installed on the strip groove 233, and both ends of the sliding rod 231 are slidably connected to the support frame 23, and the support frame 23 is in a horizontal state. The connecting shaft 21 realizes a stable connection between the conveying pipe 2 and the packing frame 172. The cooperation of the strip plate 232, the strip groove 233 and the sliding rod 231 can assist the support frame 23 in driving the conveying pipe 2 to swing back and forth smoothly, ensuring smooth adjustment of the material feeding position of the conveying pipe 2 and improving the stability of the structural linkage.

[0028] like Figures 1 to 8As shown, in a specific embodiment, a slider 24 is installed on the support frame 23. The slider 24 is connected to the guide groove 243. A guide rod 241 is movably installed through the slider 24. A guide seat 242 is installed at the end of the guide rod 241. The bottom of the guide seat 242 is welded to the side wall of the packing frame 172. The slider 24 cooperates with the plum blossom-shaped guide groove 243 to realize the guiding sliding of the support frame 23. The guide rod 241 and the guide seat 242 cooperate to limit and guide the slider 24, preventing the slider 24 from deviating during sliding, ensuring the stability of the swing trajectory of the conveying pipe 2, and further improving the uniformity of material feeding.

[0029] like Figures 1 to 8 As shown, further, an insert rod 221 is installed on the adjusting plug 22, and a ball bearing 222 is installed at the end of the insert rod 221. The ball bearing 222 is connected to the guide slope 223. A limit frame 224 is movably installed through the insert rod 221. A connecting shaft 21 is installed on the limit frame 224. A limit cover 225 is installed on the limit frame 224. A baffle 226 is installed on the insert rod 221. The baffle 226 is slidably connected to the inner wall of the limit cover 225. A limit spring 227 is sleeved on the outer wall of the insert rod 221. One end of the limit spring 227 is engaged with the side wall of the limit cover 225, and the other end of the limit spring 227 is engaged with the baffle 226. The limit spring 227 is used to drive the ball bearing 222 to always be in contact with the guide slope 223. The cooperation of the insert rod 221 and the ball bearing 222 reduces the friction between the regulating plug 22 and the guide slope 223. The limit bracket 224 and the limit cover 225 provide limit protection for the insert rod 221. The limit spring 227 ensures that the ball bearing 222 is always in contact with the guide slope 223 through the baffle 226, thus ensuring the stability and accuracy of the regulating plug 22 in regulating the flow of the delivery pipe 2 and avoiding flow regulation failure. Example

[0030] The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, a suction pipe 3 is installed at the bottom of the storage hood 32, with the end of the suction pipe 3 placed in the liquid inside the reaction tank 1. A notch 31 is provided on the suction pipe 3, and a filter cover 311 is installed on the outer wall of the notch 31. A cleaning pipe 34 is installed at the outlet of the storage hood 32, and a nozzle 341 is installed on the cleaning pipe 34, with the nozzle 341 aligned with the inner wall of the packing frame 172. A one-way valve 342 is installed on the cleaning pipe 34. The suction pipe 3 facilitates the extraction of liquid from the reaction tank 1 by the storage hood 32. The notch 31, in conjunction with the filter cover 311, prevents impurities from entering the suction pipe 3 and the storage hood 32, avoiding pipe blockage. The nozzle 341 on the cleaning pipe 34 can precisely flush the inner wall of the packing frame 172. The one-way valve 342 prevents liquid backflow, ensuring stable flushing effect and reducing slurry residue.

[0031] like Figures 1 to 8As shown, in a specific embodiment, a lead screw shaft 321 is installed at the output end of the drive motor 17. A sliding sleeve 322 is screwed onto the outer wall of the lead screw shaft 321. Three pairs of connecting rods 324 are installed on the sliding sleeve 322. The ends of the connecting rods 324 pass through the storage cover 32 and are mounted on the piston 323. The lead screw shaft 321, the sliding sleeve 322, and the connecting rods 324 cooperate with each other to convert the rotational motion of the drive motor 17 into the vertical sliding motion of the piston 323. This enables a single drive motor 17 to simultaneously drive multiple structural movements, simplifying the equipment structure and reducing energy consumption. At the same time, the three pairs of connecting rods 324 ensure smooth lifting and lowering of the piston 323, improving the liquid absorption and drainage efficiency of the storage cover 32.

[0032] like Figures 1 to 8 As shown, a positioning frame 332 is installed on the storage cover 32, and a positioning rod 331 is installed on the positioning frame 332. A sealing plug 33 is inserted into the positioning rod 331, and the sealing plug 33 seals the inlet of the storage cover 32. A positioning spring 333 is sleeved on the positioning rod 331. One end of the positioning spring 333 is engaged with the sealing plug 33, and the other end of the positioning spring 333 is engaged with the positioning frame 332. When the piston 323 moves upward, the storage cover 32 becomes a negative pressure state, which drives the sealing plug 33 to move upward, drawing the liquid inside the reaction vessel 1 into the storage cover 32. When the piston 323 stops moving, the positioning spring 333 drives the sealing plug 33 to move downward again to seal it. The positioning frame 332 and the positioning rod 331 limit and guide the sealing plug 33. The positioning spring 333 can drive the sealing plug 33 to automatically reset and seal, ensuring that the storage cover 32 can smoothly form a negative pressure to absorb liquid when the piston 323 moves up, and can effectively seal and squeeze the liquid out when it moves down, thus ensuring the stable realization of the flushing function.

[0033] The implementation principle of a microbial enhanced reactor for water treatment according to the present invention is as follows: In use, the entire reactor is first placed stably by the frame 11 and the support legs 111. The anti-slip grooves at the bottom of the support legs 111 can improve the stability of the placement. The base plate 112 further reinforces the connection between the reaction vessel 1 and the frame 11. The operator can observe the internal reaction in real time through the observation window 113 on the reaction vessel 1. Subsequently, water to be treated is introduced into the reaction tank 1 through the inlet pipe 12. The connecting flange 14 at the end of the inlet pipe 12 facilitates connection with external pipelines, and the valve can control the inlet flow rate. At the same time, in order to achieve efficient degradation of pollutants in wastewater by microorganisms and enhance the water treatment effect, HPB composite powder carrier and clean water are mixed in proportion and stirred to form a uniform slurry (HPB composite powder carrier, as a fixation carrier for microorganisms, can adsorb and fix microorganisms, improve the stability and concentration of microorganisms in the reaction system, and thus enhance the ability of microorganisms to decompose pollutants in wastewater). The cover plate 161 on the protective cover 16 is opened, and the uniform slurry is put into the packing frame 172. After the cover plate 161 is closed, the drive motor 17 is started through the controller 15. The controller 15 can precisely control the rotation speed of the drive motor 17, thereby regulating the operating status of the entire reactor and ensuring that the slurry can play its full role.

[0034] After the drive motor 17 starts, its output end drives the arched frame 171 to rotate. Since the arched frame 171 is connected to the outer wall of the packing frame 172, it drives the packing frame 172 to rotate synchronously on the reaction tank 1. During the rotation of the packing frame 172, it drives the bottom rotating and connected conveying pipe 2 to rotate together. The support frame 23, which is slidably installed on the side wall of the conveying pipe 2, has one end slidably connected to the plum blossom-shaped guide groove 243 opened on the inner side wall of the reaction tank 1 through the slider 24. Under the guidance of the guide groove 243, the support frame 23 drives the conveying pipe 2 to oscillate back and forth while rotating, thereby changing the feeding position of the conveying pipe 2. This allows the HPB composite powder carrier slurry to be evenly dispersed into the water to be treated inside the reaction tank 1, so that the HPB composite powder carrier in the slurry can fully contact the sewage, ensuring that the adsorbed microorganisms can fully act on the pollutants in the sewage, further improving the contact efficiency between microorganisms and sewage, and fully realizing the core purpose of slurry-enhanced water treatment. Meanwhile, during the rotation of the conveying pipe 2, the conical regulating plug 22 inserted at its inlet is slidably connected to the guide slope 223 on the side wall of the packing frame 172 through the top insert rod 221 and ball bearing 222. The limiting frame 224 guides the insert rod 221, and the limiting spring 227 pushes the ball bearing 222 to fit tightly against the guide slope 223 through the baffle 226. As the conveying pipe 2 swings, the guide slope 223 pushes the ball bearing 222 and the insert rod 221 to move the regulating plug 22 at the inlet of the conveying pipe 2, thereby changing the conveying flow rate of the conveying pipe 2. When the conveying pipe 2 deflects towards the center of the reaction tank 1, the regulating plug 22 moves into the inlet of the conveying pipe 2, so that the conveying flow rate decreases synchronously. This achieves coordinated control of the feeding position and the feeding flow rate, avoids local accumulation of HPB composite powder carrier slurry, ensures uniform distribution of slurry and full play of its role, and avoids uneven microbial action due to local accumulation, which would affect the water treatment effect.

[0035] During the operation of the drive motor 17, its output end simultaneously drives the lead screw shaft 321 to rotate. The sliding sleeve 322 on the outer wall of the lead screw shaft 321 moves vertically up and down under the rotation of the lead screw shaft 321. The sliding sleeve 322 drives the piston 323 to slide vertically synchronously inside the storage cover 32 through three pairs of connecting rods 324. When piston 323 moves upward, a negative pressure is formed inside storage hood 32. This negative pressure overcomes the elastic force of positioning spring 333, causing sealing plug 33 to move upward along positioning rod 331, releasing the blockage at the inlet of storage hood 32. Liquid inside reaction vessel 1 is then drawn into storage hood 32 through suction pipe 3. The notch 31 and filter cover 311 on suction pipe 3 prevent impurities from entering storage hood 32, avoiding pipe blockage. When drive motor 17 moves in the reverse direction, its output end drives lead screw shaft 321 to rotate in the reverse direction, thereby causing sliding sleeve 322 and piston 323 to move downward. At this time, the pressure inside storage hood 32 increases, pushing sealing plug 33 downward under the action of positioning spring 333. The inlet of the newly sealed storage hood 32 is simultaneously squeezed into the cleaning pipe 34. The one-way valve 342 on the cleaning pipe 34 prevents liquid backflow. Finally, the liquid is sprayed out through the nozzle 341, which is aimed at the inner wall of the packing frame 172. This effectively flushes away the residual HPB composite powder carrier slurry on the side wall of the packing frame 172, preventing slurry adhesion that could cause blockage of the packing frame 172. It also reduces the loss caused by slurry residue, prevents insufficient slurry from affecting the water treatment effect, and ensures that every portion of slurry can participate in microbial fixation and pollutant degradation, fully exerting its purpose of enhancing water treatment and ensuring the normal rotation of the packing frame 172 and the smooth delivery of the slurry.

[0036] After the reaction is complete, the controller 15 shuts off the drive motor 17 and opens the valve on the outlet pipe 13. The treated water is discharged through the outlet pipe 13, and the connecting flange 14 on the outlet pipe 13 facilitates connection with subsequent treatment pipelines. Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
