Description

Technical Field

[0001] This disclosure relates to the field of wastewater treatment technology, and in particular to a high-salt pickled vegetable wastewater treatment system and equipment. Background Technology

[0002] Pickling wastewater is high-salinity wastewater. To avoid wasting salt, it can be separated by electrodialysis. In the wastewater treatment process, it first needs to be filtered to remove large impurities before being sent to the electrodialysis system to crystallize salt. The efficiency is low and the process requires waiting. At the same time, the filtration stage of the pretreatment is also prone to clogging, which affects the overall treatment efficiency.

[0003] According to a patent document with publication number CN120247303AU, a method and equipment for treating pickled vegetable wastewater includes a treatment tank. Four partitions are symmetrically fixed at the center of the treatment tank's interior. Filter plates, which are arc-shaped, are fixed between adjacent partitions. An inlet is provided at the top of the treatment tank between two partitions. A crystallization tank is located at the rear of the treatment tank. Four electrodialysis chambers are symmetrically arranged at the center of the crystallization tank, and crystallization plates are slidably inserted into the interior of each electrodialysis chamber. Three sets of exhaust pipes are provided at the top of the crystallization tank, and condensers are fixedly installed at the outer ends of the exhaust pipes. A connecting pipe is fixed to one side of the condenser, and a biological treatment tank is fixedly connected to the other end of the connecting pipe. The outer side of the tank is equipped with a cleaning component. In use, an electric push rod drives the connecting plate to move. The first and second connecting rods move together with the connecting plate. The first connecting rod drives the scraper to move along the two partitions and filter plate surfaces at the bottom of the treatment tank, sending the accumulated impurities out from the outlet at the rear of the treatment tank. The second connecting rod penetrates into the crystallization tank and squeezes the crystallization plate, pushing the crystallization plate out from the outlet at the rear of the crystallization tank, making it convenient for manual removal of salt crystals on the crystallization plate. Regarding the above technical solution, although it can remove salt crystals in use, it cannot adjust the dosage of flocculant while simultaneously adsorbing solid impurities in the wastewater with the flocculant. It is also not convenient to extract and clean floating objects on the top of the wastewater, which is inconvenient in use. Summary of the Invention

A protruding ring is fixed on the inner wall of the movable cylinder.

[0012] Optionally, the mounting column has a mounting hole, and a rotating column is rotatably mounted inside the mounting hole.

The crushing component is installed on the inner wall of the material bucket in a staggered manner.

[0013] Optionally, a centrifuge tank is rotatably mounted inside the barrel body, the centrifuge tank has an opening, the bottom of the centrifuge tank is fixed to the output shaft, and a drain pipe is fixedly installed on the side of the barrel body.

[0014] A high-salt pickled vegetable wastewater treatment system is disclosed. The system includes a pretreatment unit, a biochemical treatment unit, an advanced treatment unit, a sludge treatment unit, and an automatic control unit. The pretreatment unit, as the core of the system's front end, is responsible for water quality and quantity regulation, preliminary removal of pollutants, and improvement of the wastewater's biodegradability. The biochemical treatment unit is the core unit for removing organic matter in the system, employing a combined anaerobic and aerobic process, suitable for pickled vegetable wastewater with high organic matter content and moderate biodegradability.

[0015] Optionally, the deep treatment unit performs deep purification on the residual COD, color, small amount of suspended solids and salts in the effluent after biochemical treatment to ensure that the effluent meets the standards.

[0016] The technical solution provided in this disclosure may include the following beneficial effects: 1. In this invention, a lifting mechanism pushes the movable cylinder upward. The movable cylinder moves the connecting rod through the fixed lugs. The moving connecting rod moves the guide block downward. When the guide block moves, it changes the position of the extraction point of the movable tube. The movable tube extracts the floating matter at the top from the outside to the inside. In addition, the movement of the guide block changes the position of the stirring column and stirring rod, so that the sewage and flocculant at different positions can come into contact and be adsorbed. The upward movement of the movable cylinder reduces the space inside the material tank, which makes it easier to increase the wind power to discharge the flocculant inside the material tank to the outside. 2. In this invention, the upward movement of the movable cylinder drives the feed pipe to move up and down inside the centrifuge barrel. The up and down movement of the feed pipe changes the height of the feed hole. The airflow blows the flocculant into the wastewater at different levels, which facilitates the uniform addition of the flocculant. Later, after the guide block moves outward, the side of the stirring column comes into contact with the inner wall of the centrifuge barrel. As the centrifuge barrel rotates, the side of the stirring column scrapes and cleans the inner wall of the centrifuge barrel, avoiding the impact of blockage at the opening. 3. In this invention, after the flocculant enters the material tank, the feed hopper is closed, and a high-pressure gas is blown in by an air pump. The high-pressure gas pushes the flocculant or other drugs to tumble and move downwards while colliding with the rotating tube. The drugs are crushed after colliding with the rotating tube, thus avoiding the impact of drug agglomeration entering the wastewater.

The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

A suction tube 11 is connected, and a support tube 31 is fixed to one end of the suction tube 11. A reinforcing rod 13 is welded between the support tube 31 and the suction tube 11. A sludge suction assembly 24 is provided, which includes a guide block 29. A movable tube 30 is fixed on the guide block 29. One end of the movable tube 30 is movably installed inside the support tube 31. A sealing ring 32 is fixed on the inner wall of the support tube 31. The sealing ring 32 is movably installed on the movable tube 30. A fixing rod 27 is welded to the top of the guide block 29. The movable tube 30 moves inside the sealing ring 32, and the movement ensures the sealing of the support tube 31. The suction generated inside the support tube 31 at one end of the movable tube 30 facilitates the entry of impurities from one end of the movable tube 30 into the support tube 31. Finally, under the suction of the extraction tube 11, it moves to the extraction seat 9 and is discharged outward.

[0022] In this embodiment, a movable seat 14 is fixedly installed on the top of the barrel 1. A slot 15 is formed on the movable seat 14, and a connecting rod 16 is movably installed inside the slot 15. One end of the connecting rod 16 is mounted on a fixed rod 27 via a rotating shaft 28. A stirring column 33 is welded to the bottom of the guide block 29, and a stirring rod 34 is welded to the side of the stirring column 33. A support seat 17 is fixed on the top of the movable seat 14, and a fixing slot 18 is formed on the side of the support seat 17. One end of the connecting rod 16 is movably installed inside the fixing slot 18. A movable cylinder 36 is movably installed inside the support seat 17. A material barrel 35 is movably installed inside the movable cylinder 36. A sealing seat 22 is fixed to one end of the material barrel 35.

An air pump 20 is fixed to one end of the air inlet pipe 21, and a fixing plate 19 is fixed to the bottom of the air pump 20. One end of the fixing plate 19 is welded to the support seat 17. Among them, the air pump 20 is a high-pressure gas generating device. The high-pressure gas generated enters the interior of the material tank 35 through the air inlet pipe 21. The high-pressure gas pushes the flocculant or other drugs to tumble. As the tumble moves downward, it collides with the rotating pipe 46. The drug is crushed after colliding with the rotating pipe 46, effectively preventing the drug from clumping.

[0023] In this embodiment, a fixed lug 39 is welded to the side of the movable cylinder 36, and one end of the connecting rod 16 is movably mounted on the fixed lug 39. A connecting block 37 is welded to the side of the movable cylinder 36, and a lifting mechanism 38 is fixed on the connecting block 37. The lifting mechanism 38 is fixedly mounted on the inner wall of the support base 17. A feed pipe 25 is welded to the bottom of the movable cylinder 36, and a feed hole 26 is opened at the bottom of the feed pipe 25. The feed pipe 25 is movably mounted inside the barrel body 1. A crushing component 40 is fixed inside the material barrel 35. The crushing component 40 includes a mounting column 43. An air guide shroud 41 is fixed on the inner wall of the material barrel 35, and a protruding ring 42 is fixed on the inner wall of the movable cylinder 36. The mounting column 43 has a mounting hole 44, and a rotating column 45 is rotatably mounted inside the mounting hole 44. A rotating tube 46 is fixed to one end of the rotating column 45, and the rotating tube 46 is rotatably mounted on the mounting column 43. The crushing component 40 is installed vertically offset on the inner wall of the material bucket 35. A centrifuge bucket 47 is rotatably mounted inside the bucket body 1. The centrifuge bucket 47 has an opening 48, and the bottom of the centrifuge bucket 47 is fixed to the output shaft 7. A drain pipe 8 is fixedly installed on the side of the bucket body 1. The lifting mechanism 38 is a linear reciprocating electric push rod. The lifting mechanism 38 is connected to an external telescopic switch via an electric wire. The telescopic switch controls the telescopic movement of the lifting mechanism 38. While the lifting mechanism 38 pushes the movable cylinder 36 upward to change the size of the storage space, the feed pipe 25 moves up and down to change the position of the feed hole 26, so as to make it easier to add flocculant or other agents evenly into the interior of the centrifuge tank 47.

[0024] A high-salt pickled vegetable wastewater treatment system includes a pretreatment unit, a biological treatment unit, an advanced treatment unit, a sludge treatment unit, and an automatic control unit. The pretreatment unit, as the core of the system's front end, is responsible for water quality and quantity regulation, preliminary pollutant removal, and improving the wastewater's biodegradability. The biological treatment unit is the core unit for removing organic matter, employing a combined anaerobic and aerobic process suitable for pickled vegetable wastewater with high organic matter content and moderate biodegradability. The advanced treatment unit deeply purifies the residual COD, color, small amounts of suspended solids, and salts in the effluent after biological treatment, ensuring the effluent meets standards. The sludge treatment unit centrally treats the excess sludge generated by each unit to avoid secondary pollution. The automatic control unit is equipped with a PLC control cabinet, online monitoring instruments, and a frequency converter control system to achieve automated start / stop of each unit's equipment and real-time monitoring and adjustment of operating parameters.

[0025] Working Principle: During use, flocculant or other agents are added to the inside of the material tank 35 through the feed hopper 23. The control valve on the feed hopper 23 is closed. Wastewater is injected into the inside of the tank 1 through the liquid inlet pipe on one side of the tank body 1. The air pump 20 is started. The air pump 20 is a high-pressure gas generator. The generated high-pressure gas enters the inside of the material tank 35 through the air inlet pipe 21. The high-pressure gas pushes the flocculant or other agents to tumble. As they tumble downwards, they collide with the rotating pipe 46, pulverizing the agents and effectively preventing agglomeration. Driven by the gas, the agents enter the inside of the movable cylinder 36 through the air guide hood 41. Finally, the airflow pushes the agents outwards from the inside of the feed hole 26 into the wastewater inside the centrifuge tank 47. As more agents are added, the amount of agents inside the material tank 35 decreases, making it impossible to accelerate the rapid discharge of the agents. At this time, the lifting mechanism 38 is activated, which moves the movable cylinder 36 upward through the connecting block 37. When the movable cylinder 36 moves upward, the fixed hanging ear 39 drives one end of the connecting rod 16 to rotate and tilt. With the movement of one end of the connecting rod 16, the connecting rod 16 drives the fixed rod 27 and the guide block 29 to move. When the guide block 29 moves, it drives the movable tube 30 to move inside the support tube 31. With the movement of the movable tube 30, the sewage pipe 10 is connected to the external suction device, and the sewage pipe 10 generates suction. Under the action of suction, the extraction tube 11 generates extraction force. The movable tube 30 moves inside the sealing ring 32. The movement ensures the sealing of the support tube 31. With the suction generated inside the support tube 31 at one end of the movable tube 30, it is easy to let impurities enter the support tube 31 from one end of the movable tube 30. Finally, under the suction of the extraction tube 11, it moves to the extraction seat 9 and is discharged outward. As the guide block 29 moves, the position of the extraction point of the movable pipe 30 is changed, so that the movable pipe 30 extracts the floating matter on the top of the wastewater from the outside to the inside. At the same time as the movable pipe 30 extracts, the drive motor 6 is started to drive the centrifuge tank 47 to rotate. The guide block 29 drives the stirring column 33 and the stirring rod 34 to change the blocking position. As the centrifuge tank 47 rotates, the wastewater and flocculant are mixed. After mixing, the flocculant adsorbs the solid impurities in the wastewater. Later, the stirring column 33 moves outward under the drive of the guide block 29. The outer wall of the stirring column 33 contacts the inner wall of the centrifuge tank 47. As the centrifuge tank 47 rotates slowly, the stirring column 33 scrapes against the inner wall of the centrifuge tank 47. The scraping reduces the impurities adhering to the inner wall of the centrifuge tank 47. Later, the rotation of the centrifuge tank 47 drives the wastewater to be discharged from the drain pipe 8.
