Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an organic wastewater treatment device and a wastewater treatment method. Background Technology

[0002] Organic wastewater mainly has the following characteristics: First, it has a high concentration of organic matter. COD is generally above 2000 mg / L, and in some cases even reaches tens or hundreds of thousands of mg / L. In contrast, BOD is relatively low, with the BOD to COD ratio in many wastewaters being less than 0.3. Second, it has a complex composition. The organic matter in wastewater containing toxic substances is predominantly aromatic compounds and heterocyclic compounds, and also contains sulfides, nitrogen compounds, heavy metals, and toxic organic matter. Third, it has high color and an unpleasant odor. Some wastewater emits a pungent, foul smell, causing adverse effects on the surrounding environment. Fourth, it is highly acidic or alkaline.

[0003] Currently, the main method for treating organic wastewater is adsorption, which involves adsorbing organic matter with resin, followed by high-temperature heating and purging regeneration for reuse. However, current wastewater treatment equipment requires adding a large number of adsorption particles to the treatment tank at once. The large amount of resin particles and the fixed tank volume result in a small volume of wastewater treated per cycle, leading to slow treatment efficiency. Furthermore, the purification efficiency gradually decreases after the resin adsorbs organic matter, necessitating the removal of resin particles, regeneration, and repeated addition to the treatment tank multiple times to maintain a certain level of purification, resulting in low efficiency. Therefore, we propose an organic wastewater treatment equipment and method to address these issues. Summary of the Invention

[0004] The purpose of this invention is to provide an organic wastewater treatment device and a wastewater treatment method to solve the problems mentioned in the background art.

A connecting rod is fixedly mounted on the end face of the drive wheel in the middle of the rotating groove. A sliding shaft is fixedly mounted on the connecting rod and engages with the U-shaped groove.

[0009] In a preferred embodiment, the stop groove is an arc-shaped structure that fits the outer circumference of the drive wheel, the rotating groove is an arc-shaped structure that matches the outer circumference of the grooved wheel, the end face of the drive wheel away from the motor is connected to the feeding mechanism, and the diameter of the sliding shaft is equal to the width of the U-shaped groove.

[0010] In a preferred embodiment, the feeding mechanism includes a horizontal shaft, which is rotatably sleeved between the inner wall of the recycling box at the bottom of the feeding box. One end of the horizontal shaft passes through the recycling box and is fixedly connected to a drive wheel. A guide rail is fixedly installed on the top of the inner cavity of the recycling box, and a sealing plate is slidably engaged between the guide rails. Multiple material dropping grooves are formed on the sealing plate, the top plate of the recycling box, and the bottom plate of the feeding box.

[0011] In a preferred embodiment, the spiral groove has a circumferential angle of 180° around the pusher barrel. Two spiral grooves are formed along the outer wall of the pusher barrel, and the two spiral grooves are connected end to end. The diameter of the pusher rod is equal to the width of the spiral groove. Multiple rows of levers are fixedly installed on the bottom side of the sealing plate away from the pusher rod, and the levers are closely attached to the top of the upper section of the conveyor belt.

[0012] In a preferred embodiment, the heating treatment mechanism includes a boiler with an oil storage chamber formed in the inner wall of the boiler. A heating pipe is sleeved on the outer wall of the boiler at the oil storage chamber.

[0013] In a preferred embodiment, a delivery pump is installed on the air inlet pipe, the heating pipe, and the return air pipe. The burner is an atomizing nozzle equipped with an igniter. The burner is also connected to a gasoline delivery pipe. The end of the exhaust pipe away from the boiler is spirally wound around the outer wall of the air inlet pipe.

[0014] A method for treating organic wastewater includes the following steps:

[0015] S1. Organic wastewater is transported to the treatment tank through water pipes and pumps. Adsorption resin particles are added to the treatment tank for organic matter adsorption treatment. During the adsorption treatment process, the resin particles after adsorbing organic matter are gradually spirally transported to the liquid surface of the treatment tank by the screw conveyor in the treatment tank. The water is filtered back into the treatment tank through the mesh on the surface of the barrel. The resin particles are then stored in the feed box through the outlet.

[0016] S2. The motor drives the drive wheel to rotate continuously. When the trough rotates to the groove wheel, the sliding shaft slides into the U-shaped groove, thereby driving the groove wheel to rotate. When the sliding shaft slides out of the U-shaped groove, the groove wheel rotates a quarter turn, and the drive wheel rotates into the stop groove, fixing the groove wheel. This allows the drive wheel to rotate continuously. When the groove wheel rotates a quarter turn intermittently, the conveyor belt moves intermittently. When the drive wheel rotates one turn, the horizontal shaft drives the push barrel to rotate one turn. At this time, the two spiral grooves push the sealing plate to move back and forth along the guide rail through the push rod, thereby making the discharge troughs alternately connected and staggered. When the conveyor belt stops, the discharge troughs drop a certain amount of vertical particles onto the conveyor belt. At the same time, when the sealing plate moves, the lever evenly distributes the resin particles on the conveyor belt. The movement of the conveyor belt and the amount of discharge are controlled in a fixed ratio through linkage to achieve quantitative and uniform discharge.

[0017] S3. When the conveyor belt moves the adsorption resin particles in the regeneration box, the air inlet pipe blows air into the regeneration box, thereby carrying out the organic matter adsorbed on the adsorption resin particles and sending it into the boiler through the return air pipe. Combined with the atomized oil droplets sprayed from the atomizing nozzle, the organic matter is fully burned and purified. The high temperature generated by combustion is added to the heat exchange oil in the oil storage chamber and introduced into the regeneration box through the heating pipe, thereby heating the adsorption resin at high temperature and promoting the release of organic matter. Combined with the airflow purging, the organic matter is removed, achieving the purpose of regenerating the adsorption resin. At the same time, the exhaust pipe can preheat the air through the spiral winding air inlet pipe, achieving the purpose of fully utilizing heat and facilitating the high-temperature purging of resin particles, thereby recycling and regenerating the adsorption resin.

[0018] S4. After the adsorption resin particles are regenerated, they slide down through the guide plate and discharge port into the collection box for collection. Then, they are transported back to the treatment tank by the screw conveyor in the collection box to adsorb organic matter in the wastewater, thereby achieving continuous recycling of the adsorption resin, reducing the amount of resin in the treatment tank, increasing the wastewater treatment efficiency, and fully purifying the wastewater through the regenerated resin particles, thus improving the degree of purification.

[0019] The beneficial effects of the present invention are:

[0020] 1. The motor drives the drive wheel to rotate continuously. When the trough rotates to the groove wheel, the sliding shaft slides into the U-shaped groove, thereby driving the groove wheel to rotate. When the sliding shaft slides out of the U-shaped groove, the groove wheel rotates a quarter turn, and the drive wheel rotates into the stop groove, fixing the groove wheel. This allows the drive wheel to rotate continuously. When the groove wheel rotates a quarter turn intermittently, the conveyor belt moves intermittently. When the drive wheel rotates one turn, the horizontal shaft drives the push barrel to rotate one turn. At this time, the two spiral grooves push the sealing plate to move back and forth along the guide rail through the push rod, thereby making the discharge troughs alternately connected and staggered. When the conveyor belt stops, the discharge troughs drop a certain amount of vertical particles onto the conveyor belt. At the same time, when the sealing plate moves, the resin particles are evenly distributed on the conveyor belt through the lever. The movement of the conveyor belt and the amount of material dropped are controlled in a fixed ratio through linkage to achieve quantitative and uniform material dropping, which facilitates resin regeneration.

[0021] 2. When the conveyor belt moves the adsorption resin particles in the regeneration box, the air inlet pipe blows air into the regeneration box, thereby carrying out the organic matter adsorbed on the adsorption resin particles and sending it into the boiler through the return air pipe. Combined with the atomized oil droplets sprayed from the atomizing nozzle, the organic matter is fully burned and purified. The high temperature generated by combustion is added to the heat exchange oil in the oil storage chamber and introduced into the regeneration box through the heating pipe, thereby heating the adsorption resin at high temperature and promoting the release of organic matter. Combined with the airflow purging, the organic matter is removed, achieving the purpose of regenerating the adsorption resin. At the same time, the exhaust pipe can preheat the air through the spiral winding air inlet pipe, achieving the purpose of fully utilizing heat and facilitating the high-temperature purging of resin particles, thereby recycling and regenerating the adsorption resin.

[0022] 3. After regeneration, the adsorption resin particles slide down through the guide plate and discharge port into the collection box for collection. Then, they are transported back to the treatment tank by the screw conveyor inside the collection box to adsorb organic matter in the wastewater, thereby achieving continuous recycling of the adsorption resin, reducing the amount of resin in the treatment tank, lowering costs, increasing wastewater treatment efficiency, and fully purifying the wastewater through the regenerated resin particles, thus improving the degree of purification.

The burner 85 is also connected to a gasoline delivery pipe. The end of the exhaust pipe 86 away from the boiler 81 is spirally wound around the outer wall of the air inlet pipe 83.

[0041] A method for treating organic wastewater includes the following steps:

[0042] S1. Organic wastewater is transported to treatment tank 1 through water pipes and pumps. Adsorption resin particles are added to treatment tank 1 for organic matter adsorption treatment. During the adsorption treatment process, the resin particles after adsorbing organic matter are gradually spirally transported to the liquid surface of treatment tank 1 by the screw conveyor 2 in treatment tank 1. The water is filtered back to treatment tank 1 through the mesh on the surface of the barrel 21. The resin particles are then stored in the feed box 4 through the outlet 25.

[0043] S2. Motor 62 drives the drive wheel 63 to rotate continuously. When the trough 67 rotates to the grooved wheel 64, the sliding shaft 69 slides into the U-shaped groove 66, thereby pushing the grooved wheel 64 to rotate. When the sliding shaft 69 slides out of the U-shaped groove 66, the grooved wheel 64 rotates a quarter turn, and the drive wheel 63 rotates into the stop groove 65, fixing the grooved wheel 64. This achieves continuous rotation of the drive wheel 63 and intermittent rotation of the grooved wheel 64, causing the conveyor belt 32 to move intermittently. When the drive wheel 63 rotates one revolution... The horizontal shaft 71 drives the push barrel 72 to rotate one revolution. At this time, the two spiral grooves 76 push the sealing plate 74 to move back and forth along the guide rail 73 through the push rod 77, so that the discharge chute 75 alternately connects and staggers. When the conveyor belt 32 stops, the discharge chute 75 drops a certain amount of vertical particles onto the conveyor belt 32. At the same time, when the sealing plate 74 moves, the resin particles are evenly distributed on the conveyor belt 32 through the lever 78. The movement of the conveyor belt 32 and the amount of discharge are controlled in a fixed ratio through linkage to achieve quantitative and uniform discharge.

[0044] S3. When the conveyor belt 32 moves the adsorption resin particles in the regeneration box 3, the air inlet pipe 83 blows air into the regeneration box 3, thereby carrying out the organic matter adsorbed on the adsorption resin particles and sending it into the boiler 81 through the return air pipe 84. Combined with the atomized oil droplets sprayed from the atomizing nozzle, the organic matter is fully burned and purified. The high temperature generated by combustion is added to the heat exchange oil in the oil storage chamber and introduced into the regeneration box 3 through the heating pipe 82, thereby heating the adsorption resin at high temperature and promoting the dissipation of organic matter. Combined with the airflow purging, the organic matter is removed, achieving the purpose of regenerating the adsorption resin. At the same time, the exhaust pipe 86 can preheat the air by spirally winding the air inlet pipe 83, achieving the purpose of fully utilizing heat and facilitating the high-temperature purging of resin particles, thereby recycling and regenerating the adsorption resin.

[0045] S4. After the adsorption resin particles are regenerated, they slide down through the guide plate 34 and the discharge port 33 into the collection box 5 for collection. Then, they are transported again to the treatment tank 1 by the screw conveyor 2 in the collection box 5 to adsorb organic matter in the wastewater, thereby achieving continuous recycling of the adsorption resin, reducing the amount of resin in the treatment tank 1, increasing the wastewater treatment efficiency, and fully purifying the wastewater through the regenerated resin particles, thus improving the degree of purification.

[0046] In operation, organic wastewater is transported to treatment tank 1 via water pipes and pumps. Adsorption resin particles are added to treatment tank 1 for organic matter adsorption. During adsorption, the resin particles, after adsorption, are gradually conveyed to the surface of the liquid in treatment tank 1 by a screw conveyor 2 within treatment tank 1. Water is filtered and returned to treatment tank 1 through the mesh on the surface of the barrel 21. The resin particles then enter the feed box 4 through outlet 25 for storage. Motor 62 drives the drive wheel 63 to rotate continuously. When the rotating trough 67 reaches the grooved wheel 64, the sliding shaft 69 slides into the U-shaped groove 66, thereby driving the grooved wheel 64 to rotate. When the sliding shaft 69 slides out of the U-shaped groove 66... At this time, the grooved wheel 64 rotates one-quarter of a turn, and the drive wheel 63 rotates into the stop groove 65, fixing the grooved wheel 64. This allows the drive wheel 63 to rotate continuously, while the grooved wheel 64 rotates intermittently, causing the conveyor belt 32 to move intermittently. When the drive wheel 63 rotates one turn, the horizontal shaft 71 drives the push barrel 72 to rotate one turn. At this time, the two spiral grooves 76 push the sealing plate 74 to move back and forth along the guide rail 73 through the push rod 77, thus causing the discharge chute 75 to alternately connect and stagger. When the conveyor belt 32 stops, the discharge chute 75 drops a certain amount of vertical particles onto the conveyor belt 32. At the same time, when the sealing plate 74 moves, the lever 78 evenly distributes the resin particles. The material is evenly distributed on the conveyor belt 32. The movement and discharge of the conveyor belt 32 are controlled in a fixed ratio to achieve quantitative and uniform discharge. When the conveyor belt 32 moves the adsorbent resin particles in the regeneration box 3, the air inlet pipe 83 blows air into the regeneration box 3, thereby carrying out the organic matter adsorbed on the adsorbent resin particles. This organic matter is then sent into the boiler 81 through the return air pipe 84. Combined with the atomized oil droplets sprayed from the atomizing nozzle, the organic matter is fully burned and purified. The high temperature generated by combustion is added to the heat exchange oil in the oil storage chamber and introduced into the regeneration box 3 through the heating pipe 82, thereby heating the adsorbent resin at high temperature and promoting the dissipation of organic matter. Combined with the airflow purging, the adsorbent resin is further purified. Organic matter is removed to regenerate the adsorption resin. At the same time, the exhaust pipe 86 preheats the air by spirally winding the air inlet pipe 83, making full use of heat and facilitating high-temperature purging of resin particles, thereby recycling and regenerating the adsorption resin. After regeneration, the adsorption resin particles slide down through the guide plate 34 and the discharge port 33 into the collection box 5 for collection. Then, they are transported again to the treatment tank 1 by the screw conveyor 2 in the collection box 5 to adsorb organic matter in the wastewater, thereby achieving continuous recycling of the adsorption resin, reducing the amount of resin in the treatment tank 1, increasing the wastewater treatment efficiency, and fully purifying the wastewater through the regenerated resin particles, thus improving the purification level.

6. A method for treating organic wastewater using the organic wastewater treatment equipment of claim 5, characterized in that: The steps include: S1, organic wastewater is transported to a treatment tank (1) through a water pipe and a water pump, and adsorption resin particles are added to the treatment tank (1) to perform organic matter adsorption treatment. During the adsorption treatment process, the resin particles after adsorbing organic matter are gradually spirally transported to the liquid surface of the treatment tank (1) through a screw conveyor (2) in the treatment tank (1), and water is filtered and returned to the treatment tank (1) through mesh holes on the surface of a barrel (21), and the resin particles enter a feed box (4) through an outlet (25) for storage; S2, the motor (62) drives the driving wheel (63) to rotate continuously. When the rotating groove (67) rotates to the groove wheel (64), the sliding shaft (69) slides into the U-shaped groove (66), thereby driving the groove wheel (64) to rotate. When the sliding shaft (69) slides out of the U-shaped groove (69), the groove wheel (64) rotates a quarter of a turn, and the driving wheel (63) rotates into the stop groove (65), so that the groove wheel (64) is fixed, thereby realizing the continuous rotation of the driving wheel (63). The groove wheel (64) rotates intermittently by a quarter of a turn, and the conveyor belt (32) moves intermittently, and the driving wheel (63) rotates by a quarter of a turn. When the conveyor belt (32) rotates one circle, the horizontal shaft (71) drives the push barrel (72) to rotate one circle. At this time, the two spiral grooves (76) push the sealing plate (74) to move back and forth along the guide rail (73) through the push rod (77), so that the material dropping grooves (75) are alternately connected and staggered. When the conveyor belt (32) stops, the material dropping grooves (75) drop a fixed amount of vertical particles onto the conveyor belt (32). At the same time, when the sealing plate (74) moves, the resin particles are evenly distributed on the conveyor belt (32) through the lever (78). The movement amount of the conveyor belt (32) and the amount of material dropped are controlled in a fixed ratio through linkage, so that a fixed amount of material is dropped evenly. S3, when the conveyor belt (32) drives the adsorbent resin particles to move in the regeneration box (3), the air inlet pipe (83) blows air into the regeneration box (3), thereby taking out the organic matter adsorbed on the adsorbent resin particles, and sending it into the boiler (81) through the return air pipe (84), and combining with the atomized oil droplets sprayed by the atomizing nozzle, the organic matter is fully burned and purified, and the high temperature generated by the combustion heats the heat exchange oil in the oil storage chamber, and the high-temperature heat exchange oil is introduced into the regeneration box (3) through the heating pipe (82), thereby heating the adsorbent resin at high temperature, promoting the emission of organic matter, and combining with the air flow to purge, so as to remove the organic matter and achieve the purpose of regenerating the adsorbent resin. At the same time, the tail gas pipe (86) can preheat the air by spirally winding the air inlet pipe (83), so as to achieve the purpose of fully utilizing the heat, and facilitate the high-temperature purge of the resin particles, so as to circulate and regenerate the adsorbent resin; S4. After the adsorption resin particles are regenerated, they slide through the guide plate (34) and the discharge port (33) into the collection box (5) for collection, and then are transported to the treatment tank (1) again through the screw conveyor (2) in the collection tank (5) to adsorb organic matter in the wastewater, thereby achieving continuous recycling of the adsorption resin, reducing the amount of resin in the treatment tank (1), increasing the wastewater treatment efficiency, and being able to fully purify the wastewater through the regenerated resin particles, thereby improving the degree of purification.
