Description

Technical Field

[0001] This application relates to the field of wastewater treatment, and in particular to a high-concentration traditional Chinese medicine wastewater treatment system. Background Technology

[0002] The main raw materials for traditional Chinese medicine (TCM) manufacturing are all natural organic substances, containing lignin, lignin, pectin, hemicellulose, waxes, and many other complex organic compounds. During the production process, the colloidal components interact through emulsification, hydrolysis, metathesis, and dissolution, with the final products being carbohydrates such as xylose, galactose, mannose, and glucose. During the rinsing process, some of these organic substances enter the wastewater, making the composition of TCM wastewater complex, with high concentrations of dissolved substances, colloids, and solids. A TCM wastewater treatment system includes three stages: pretreatment, biological treatment, and physicochemical post-treatment.

[0003] After collection, general wastewater enters a traditional Chinese medicine wastewater pond. Pretreatment involves pumping the wastewater into a rotary screen, which traps suspended solids and floating matter in the drum. The effluent then enters a regulating tank for water quality and quantity adjustment. Next, it is pumped into the inlet of a suspended media filter. After water distribution, it undergoes sludge-water separation via inclined plates, followed by further removal of suspended particles through the suspended media. The effluent then enters a plate and frame filter press, where the 2% solids content of the feed sludge-water mixture is pressed into 40% solids content sludge cakes, removing most of the suspended solids (SS). The effluent then enters a pressurized dissolved air flotation unit to remove suspended solids and total phosphorus. Next, the effluent enters a micro-electrolysis oxidation tank with a current density of 2–5 A / dm² and an electrolysis time of 20–40 minutes, effectively oxidizing and reducing organic and inorganic matter, improving the wastewater's biodegradability. Finally, the effluent enters a hydrolysis acidification tank for biological treatment, where hydrolysis further enhances the wastewater's biodegradability. The wastewater then enters an internal circulation anaerobic reactor for efficient COD removal. Next, it enters a secondary AO+MBR system to remove organic matter, ensuring the wastewater meets discharge standards. If the wastewater fails to meet standards, it enters a coagulation sedimentation reactor for physicochemical post-treatment, where total phosphorus and total nitrogen are removed through chemical reactions. Following this, a fixed-bed adsorption tower removes color and odor. Regeneration is achieved by directly passing direct current into saturated carbon; once the activation temperature is reached, steam is introduced to complete the activation process. The treated water then enters an external discharge tank for compliant discharge.

[0004] After a period of use, the activated carbon plates in the fixed-bed adsorption tower need to be removed for activation and regeneration. However, the activated carbon plates in the fixed-bed adsorption tower are in wastewater. When removing them, the wastewater in the fixed-bed adsorption tower needs to be drained before the activated carbon plates can be removed. This process is relatively complicated and has low work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a high-concentration traditional Chinese medicine wastewater treatment system to solve the problems mentioned in the background art.

[0006] This utility model provides a high-concentration traditional Chinese medicine wastewater treatment system, including a coagulation sedimentation tank. An activated carbon adsorption tank is located on one side of the coagulation sedimentation tank, and an external discharge tank is located on the other side of the activated carbon adsorption tank. A conveying valve pipe is connected to the left side of the coagulation sedimentation tank, and connecting valve pipes are connected to both sides of the activated carbon adsorption tank. The connecting valve pipes on both sides of the activated carbon adsorption tank are connected to the coagulation sedimentation tank and the external discharge tank. An external discharge valve pipe is connected to the right side of the external discharge tank. Multiple support frames are slidably connected to the inner wall of the activated carbon adsorption tank, and plate grooves are formed on the side walls of the support frames. Activated carbon plates are slidably connected to the inner walls of the plate grooves. The biochemically treated wastewater enters the coagulation sedimentation tank through the conveying valve pipes for total phosphorus and total nitrogen determination. After biochemical sedimentation treatment, the wastewater enters the activated carbon adsorption tank through the connecting valve pipe on the right side of the coagulation sedimentation tank. There, it undergoes adsorption treatment by the activated carbon plates. The treated wastewater then enters the discharge tank through the connecting valve pipe on the right side of the activated carbon adsorption tank and is subsequently discharged. The activated carbon adsorption tank is equipped with a lifting device. When activated carbon plates need to be treated, the lifting device raises the support frame above the water surface of the activated carbon adsorption tank, allowing the activated carbon plates in the plate slots to be extracted for activation treatment. This improves maintenance convenience. Furthermore, the plate slots are equipped with a limiting device to fix the activated carbon plates in the slots, preventing them from moving freely.

[0007] Preferably, the lifting device includes a parts compartment inside the activated carbon adsorption tank, and two synchronous pulleys are provided inside the conical sliding sleeve. The synchronous pulleys are engaged with a synchronous belt, and a threaded rod is fixedly connected to the top surface of the synchronous pulley. The threaded rod is threadedly connected to the support frame, and a connecting rod is fixedly connected to one end of the threaded rod. A connecting block is rotatably connected to the side wall of the connecting rod, and the connecting block is fixedly installed on the top surface of the activated carbon adsorption tank.

[0008] By adopting the above technical solution, when it is necessary to remove the activated carbon plate, the connecting rod can be rotated. Through the cooperation of the synchronous wheel and the synchronous belt, the connecting rod will drive the two threaded rods to rotate simultaneously, causing the support frame to rise. After the support frame rises above the water surface and is on one side of the connecting rod, the activated carbon plate can be pulled to slide out of the plate groove, thus enabling the activation treatment of the activated carbon plate. The connecting rod is smaller than the threaded rod and slides through the support frame. When the support frame rises to one side of the connecting rod, it will stop moving, allowing multiple support frames inside the activated carbon adsorption tank to be moved to one side of the connecting rod, and the activated carbon plate in the support frame can be removed.

[0009] Preferably, the limiting device includes two spring chambers formed on the inner wall of the plate groove, and a T-shaped inclined limiting block is slidably connected to the inner wall of the spring chamber. A limiting spring is provided inside the spring chamber, and one end of the limiting spring is fixedly connected to the side wall of the T-shaped inclined limiting block, and the other end of the limiting spring is fixedly connected to the side wall of the spring chamber.

[0010] By adopting the above technical solution, when the activated carbon plate is installed, the activated carbon plate will slide along the inclined surface of the T-shaped inclined limiting block, thereby pushing the T-shaped inclined limiting block to squeeze the limiting spring into the spring chamber. After the activated carbon plate slides into the plate groove, the limiting spring will rebound, causing the T-shaped inclined limiting block to extend out of the spring chamber and be located on one side of the plate groove, thus completing the limiting and fixing work of the plate groove.

[0011] Preferably, the surface of the activated carbon plate is provided with a strip groove, and a pull rod is fixedly installed on the inner wall of the strip groove.

[0012] By adopting the above technical solution, and by setting up a pull rod, the activated carbon plate can be moved by holding the pull rod, which facilitates disassembly.

[0013] Preferably, a plurality of fixing blocks are fixedly installed on the top surface of the activated carbon adsorption tank, and fixing rods are fixedly installed on the side walls of the fixing blocks, the fixing rods being slidably connected to the support frame.

[0014] By adopting the above technical solution, and by setting a fixed rod that is slidably connected to the support frame, a certain limiting support function will be provided to one end of the support frame, so as to facilitate the vertical movement of the support frame.

[0015] Preferably, a strip block is fixedly installed on the surface of the connecting rod, and a rotating rod is fixedly installed on the surface of the strip block, with a rubber sleeve fitted on the side wall of the rotating rod.

[0016] By adopting the above technical solution, the connecting rod can be rotated by holding and pushing the rotating rod, and the strip block can be used to drive the connecting rod to rotate, which facilitates disassembly and installation. The rubber sleeve can provide operating comfort.

[0017] Preferably, a tapered sliding sleeve is provided on one side of the connecting rod, and the tapered sliding sleeve is fixedly installed on the top end of the threaded rod.

[0018] By adopting the above technical solution and setting a tapered sliding sleeve, the tapered sliding sleeve will provide a certain guiding effect, making it easier for the support frame to slide into one side of the threaded rod and avoiding collision with the top of the threaded rod.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The biochemically treated wastewater will enter the coagulation sedimentation tank through the conveying valve pipe for biochemical precipitation treatment of total phosphorus and total nitrogen. After that, it will enter the activated carbon adsorption tank through the connecting valve pipe on the right side of the coagulation sedimentation tank, where it will be adsorbed by the activated carbon plates. The treated wastewater will then enter the discharge tank through the connecting valve pipe on the right side of the activated carbon adsorption tank, and will be discharged from the discharge valve pipe.

[0021] 2. When the activated carbon plate needs to be removed, the connecting rod can be rotated. Through the cooperation of the synchronous pulley and the synchronous belt, the connecting rod will drive the two threaded rods to rotate simultaneously, causing the support frame to rise. After the support frame rises above the water surface and is on one side of the connecting rod, the activated carbon plate can be pulled to slide out of the plate slot, and the activated carbon plate can be activated. The connecting rod is smaller than the threaded rod and slides to connect with the support frame. When the support frame rises to one side of the connecting rod, it will stop moving, so that multiple support frames inside the activated carbon adsorption tank can be moved to one side of the connecting rod to remove the activated carbon plate in the support frame.

[0022] 3. When installing the activated carbon plate, the activated carbon plate will slide along the inclined surface of the T-shaped inclined limiting block, thereby pushing the T-shaped inclined limiting block to squeeze the limiting spring into the spring chamber. After the activated carbon plate slides into the plate groove, the limiting spring will rebound, causing the T-shaped inclined limiting block to extend out of the spring chamber and be located on one side of the plate groove, thus completing the limiting and fixing work of the plate groove.

[0030] The following is in conjunction with the appendix Figure 1 - Figure 6 This application will be described in further detail.

[0031] This application discloses a high-concentration traditional Chinese medicine wastewater treatment system.

[0032] Reference Figure 1 and Figure 2 A high-concentration traditional Chinese medicine wastewater treatment system includes a coagulation sedimentation tank 2, an activated carbon adsorption tank 3 on one side of the coagulation sedimentation tank 2, and an external discharge tank 4 on one side of the activated carbon adsorption tank 3. A conveying valve pipe 1 is connected to the left side of the coagulation sedimentation tank 2, and connecting valve pipes 5 are connected to both sides of the activated carbon adsorption tank 3. The connecting valve pipes 5 on both sides of the activated carbon adsorption tank 3 are connected to the coagulation sedimentation tank 2 and the external discharge tank 4. An external discharge valve pipe 6 is connected to the right side of the external discharge tank 4. Multiple support frames 10 are slidably connected to the inner wall of the activated carbon adsorption tank 3, and plate grooves 11 are opened on the side walls of the support frames 10. Activated carbon plates 12 are slidably connected to the inner wall of the plate grooves 11. The biochemically treated wastewater enters the coagulation sedimentation tank 2 through the conveying valve pipe 1 for biochemical precipitation treatment of total phosphorus and total nitrogen. Afterwards, the wastewater enters the activated carbon adsorption tank 3 through the connecting valve pipe 5 on the right side of the coagulation sedimentation tank 2. It is then adsorbed by the activated carbon plates 12 in the activated carbon adsorption tank 3. The treated wastewater enters the discharge tank 4 through the connecting valve pipe 5 on the right side of the activated carbon adsorption tank 3, and is then discharged from the discharge valve pipe 6. The activated carbon adsorption tank 3 is equipped with a lifting device. When the activated carbon plates 12 need to be treated, the lifting device raises the support frame 10 above the water surface of the activated carbon adsorption tank 3. Then, the activated carbon plates 12 in the plate trough 11 can be extracted for activated carbon activation treatment, improving the convenience of maintenance. The plate trough 11 is equipped with a limiting device, which can fix the activated carbon plates 12 in the plate trough 11 to prevent the activated carbon plates 12 from moving at will.

[0033] refer to Figure 1The lifting device includes a parts compartment 26 located inside the activated carbon adsorption tank 3. Two synchronous pulleys 7 are located inside the conical sliding sleeve 25. The synchronous pulleys 7 are engaged with a synchronous belt 8, and a threaded rod 9 is fixedly connected to the top surface of each synchronous pulley 7. The threaded rod 9 is threadedly connected to the support frame 10, and a connecting rod 13 is fixedly connected to one end of the threaded rod 9. A connecting block 14 is rotatably connected to the side wall of the connecting rod 13, and the connecting block 14 is fixedly installed on the top surface of the activated carbon adsorption tank 3. When the activated carbon plate 12 needs to be removed, the connecting rod 13 can be rotated, and the connection is achieved through the cooperation of the synchronous pulleys 7 and the synchronous belt 8. Rod 13 will drive the two threaded rods 9 to rotate simultaneously, causing the support frame 10 to rise. After the support frame 10 rises above the water surface and is on one side of the connecting rod 13, the activated carbon plate 12 can be pulled to slide out of the plate groove 11, so that the activated carbon plate 12 can be activated. The connecting rod 13 is smaller than the threaded rod 9 and is slidably connected to the support frame 10. When the support frame 10 rises to one side of the connecting rod 13, it will stop moving, so that multiple support frames 10 inside the activated carbon adsorption tank 3 can be moved to one side of the connecting rod 13 to remove the activated carbon plate 12 from the support frame 10.

[0034] refer to Figure 5 and Figure 6 The limiting device includes two spring chambers 15 formed on the inner wall of the plate groove 11, and a T-shaped inclined limiting block 16 is slidably connected to the inner wall of the spring chamber 15. A limiting spring 17 is provided inside the spring chamber 15, and one end of the limiting spring 17 is fixedly connected to the side wall of the T-shaped inclined limiting block 16, and the other end of the limiting spring 17 is fixedly connected to the side wall of the spring chamber 15. When the activated carbon plate 12 is installed, the activated carbon plate 12 will slide along the inclined surface of the T-shaped inclined limiting block 16, thereby pushing the T-shaped inclined limiting block 16 to squeeze the limiting spring 17 into the spring chamber 15. After the activated carbon plate 12 slides into the plate groove 11, the limiting spring 17 will rebound, causing the T-shaped inclined limiting block 16 to extend out of the spring chamber 15 and be located on one side of the plate groove 11, thus completing the limiting and fixing work of the plate groove 11.

[0035] refer to Figure 5 The activated carbon plate 12 has a strip groove 18 on its surface, and a pull rod 19 is fixedly installed on the inner wall of the strip groove 18. By setting the pull rod 19, the activated carbon plate 12 can be moved by holding the pull rod 19, which facilitates disassembly.

[0036] refer to Figure 3 Multiple fixing blocks 20 are fixedly installed on the top surface of the activated carbon adsorption tank 3, and fixing rods 21 are fixedly installed on the side walls of the fixing blocks 20. The fixing rods 21 are slidably connected to the support frame 10. By setting the fixing rods 21, the fixing rods 21 slidably connected to the support frame 10 will provide a certain limiting support function for one end of the support frame 10, so as to facilitate the vertical movement of the support frame 10.

[0037] refer to Figure 4 A strip block 22 is fixedly installed on the surface of the connecting rod 13, and a rotating rod 23 is fixedly installed on the surface of the strip block 22. A rubber sleeve 24 is fitted on the side wall of the rotating rod 23. By holding and pushing the rotating rod 23, the connecting rod 13 can be rotated through the strip block 22, which facilitates disassembly and installation. The rubber sleeve 24 provides operating comfort.

[0038] refer to Figure 4 A tapered sliding sleeve 25 is provided on one side of the connecting rod 13, and the tapered sliding sleeve 25 is fixedly installed on the top of the threaded rod 9. By setting the tapered sliding sleeve 25, the tapered sliding sleeve 25 will provide a certain guiding effect, so that the support frame 10 can slide into one side of the threaded rod 9 and avoid collision with the top of the threaded rod 9.

[0039] The implementation principle of a high-concentration traditional Chinese medicine wastewater treatment system in this application embodiment is as follows: the wastewater after biochemical treatment enters the coagulation sedimentation tank 2 through the conveying valve pipe 1 for biochemical precipitation treatment of total phosphorus and total nitrogen. Then, it enters the activated carbon adsorption tank 3 through the connecting valve pipe 5 on the right side of the coagulation sedimentation tank 2, and is adsorbed by the activated carbon plates 12 in the activated carbon adsorption tank 3. The treated wastewater enters the discharge tank 4 through the connecting valve pipe 5 on the right side of the activated carbon adsorption tank 3, and is then discharged from the discharge valve pipe 6.

[0040] When the activated carbon plate 12 needs to be removed, the connecting rod 13 can be rotated. Through the cooperation of the synchronous wheel 7 and the synchronous belt 8, the connecting rod 13 will drive the two threaded rods 9 to rotate simultaneously, causing the support frame 10 to rise. After the support frame 10 rises above the water surface and is on one side of the connecting rod 13, the activated carbon plate 12 can be pulled to slide out of the plate groove 11, and the activation treatment of the activated carbon plate 12 can be carried out. The connecting rod 13 is smaller than the threaded rod 9 and is slidably connected to the support frame 10. When the support frame 10 rises to one side of the connecting rod 13, it will stop moving, so that multiple support frames 10 inside the activated carbon adsorption tank 3 can be moved to one side of the connecting rod 13 to remove the activated carbon plate 12 from the support frame 10.

[0041] When the activated carbon plate 12 is installed, the activated carbon plate 12 will slide along the inclined surface of the T-shaped inclined limiting block 16, thereby pushing the T-shaped inclined limiting block 16 to squeeze the limiting spring 17 into the spring chamber 15. After the activated carbon plate 12 slides into the plate groove 11, the limiting spring 17 will rebound, causing the T-shaped inclined limiting block 16 to extend out of the spring chamber 15 and be located on one side of the plate groove 11, thus completing the limiting and fixing work of the plate groove 11.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
