Description

Technical Field

[0001] The present invention belongs to the technical field of industrial organic wastewater, in particular to a high-concentration industrial organic wastewater purification treatment device and a treatment method thereof. Background Art

[0002] High-concentration industrial organic wastewater refers to organic wastewater discharged during industrial production with a chemical oxygen demand (COD) significantly higher than that of conventional wastewater. Its core characteristics are as follows: Concentration threshold: In internationally accepted standards, the COD concentration is usually ≥2000 mg / L; some industries (such as chemicals and pharmaceuticals) have higher definition standards, COD ≥3000 mg / L, and can even reach tens of thousands to hundreds of thousands of mg / L; Pollutant characteristics: A high proportion of organic matter (such as oils, dyes, antibiotics, etc.) and may be accompanied by complex components such as ammonia nitrogen, heavy metals, acids and alkalis; it often contains biodegradable substances (such as polycyclic aromatic hydrocarbons, pesticide residues) and toxic substances, and the biodegradability varies significantly.

[0003] In the current technical field, continuous treatment methods are typically used to treat large amounts of wastewater. However, the treatment of organic wastewater requires the introduction of ozone or ozone water, leveraging its strong oxidizing properties to directly decompose the organic matter in the wastewater. During this continuous treatment process, sufficient reaction time between the wastewater and ozone or ozone water is necessary to ensure the oxidative degradation of the organic matter. Consequently, existing treatment equipment is often excessively long, resulting in a large footprint. Furthermore, during long continuous reactions, solid impurities accumulate on the catalyst surface due to the characteristics of the wastewater composition, byproducts of oxidative degradation, and products of incomplete degradation of organic matter. This not only affects the catalyst's catalytic efficiency with ozone or ozone water, but also significantly reduces the oxidative degradation efficiency of organic matter in the organic wastewater.

[0020] 1.

The rotation of the mesh drum can generate centrifugal force, which can not only use the centrifugal force to throw out impurities attached to the surface of the mesh drum, but also effectively avoid the attachment of impurities. At the same time, the rotation operation of the mesh drum can ensure that ozone or ozone water can flow out evenly through the mesh drum, ensuring the comprehensive contact between the catalyst and ozone or ozone water, ensuring the catalytic effect on them, and at the same time, through the flow unit, the flow stroke of the sewage is increased, ensuring the contact reaction time between the sewage and ozone or ozone water.

The inner rotating wall of the second auger piece and the inside of the mesh cylinder are not in direct contact, but are in contact through the bristles. At the same time, because the second gear is located in the second annular rack and the first gear is located outside the first annular rack, the second auger piece and the mesh cylinder have opposite rotation directions, thereby ensuring that the surface of the mesh cylinder is brushed, further improving the cleaning effect.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] like Figures 1 to 10As shown, a high-concentration industrial organic wastewater purification treatment device described in an embodiment of the present invention includes a treatment barrel 1; a first circular cavity 11 is opened in the treatment barrel 1; a first square cavity 12 is opened at the top of the first circular cavity 11; a first cavity 14 is opened in the treatment barrel 1, and the first cavity 14 is located on one side of the first circular cavity 11 and the first square cavity 12; the first circular cavity 11 is interconnected with the first cavity 14 through a flow unit; a water inlet pipe 13 is fixedly connected to the top of the treatment barrel 1 at a position away from the first cavity 14, and the water inlet pipe 13 and the first square cavity 12 are interconnected; a water outlet pipe 15 is fixedly connected to the side wall of the first cavity 14, and the water outlet pipe 15 and the first cavity 14 are interconnected; an air outlet pipe 16 is opened at the top of the first cavity 14; a first pipe 2 is rotatably connected to the middle of the treatment barrel 1; the first pipe 2 extends into the end of the first circular cavity 11 A group of L-shaped tubes 21 are fixedly connected to the wall, and the first pipe 2 and the L-shaped tube 21 are connected to each other; a mesh tube 23 is sleeved on the horizontal tube of the L-shaped tube 21; a first through hole 22 is opened on the outer wall of the horizontal tube of the L-shaped tube 21; a catalyst material is placed in the mesh tube 23; the mesh tube 23 is rotated by a rotation unit; a servo motor 24 is fixedly connected to the side wall of the treatment tube 1 through a connecting rod, and the servo motor 24 drives the first pipe 2 to rotate through gear engagement; an early warning water level monitor 17 is provided at the top of the treatment tube 1; in the current technical field, continuous treatment methods are usually used to treat large amounts of sewage. However, for the treatment of organic wastewater, ozone or ozone water needs to be introduced to use its strong oxidizing properties to directly decompose organic matter in the wastewater. During the continuous treatment process, in order to ensure the oxidative degradation of organic matter, it is necessary to ensure that the wastewater and ozone or ozone water have sufficient reaction time.Therefore, the existing treatment devices are often too long, resulting in a large space occupation; at the same time, during the long-term continuous reaction, due to the characteristics of the sewage components, the by-products produced by oxidation degradation and the products of incomplete degradation of organic matter, some solid impurities will accumulate on the catalyst surface, which not only affects the catalytic efficiency of the catalyst for ozone or ozone water, but also significantly reduces the oxidation degradation efficiency of organic matter in the organic wastewater; therefore, when the present invention is working, the sewage will flow into the first circular cavity 11 through the first square cavity 12 through the water inlet pipe 13, and at the same time, the ozone or ozone water will enter the L-shaped tube 21 through the first pipe 2, and then enter the sleeve mesh cylinder 23 through the first through hole 22, and then pass through the sleeve The catalyst in the mesh drum 23 enters the first circular cavity 11. Through the action of the catalyst, ozone is more effectively decomposed to produce hydroxyl radicals, a strong oxidant, thereby accelerating the oxidative decomposition of organic matter. The servo motor 24 drives the first pipe 2 to rotate through gear meshing, which will drive a group of L-shaped tubes 21 and the mesh drum 23 to rotate, thereby making the water flow in a stirring state, which can effectively allow ozone or ozone water to quickly mix and contact with sewage. At the same time, the mesh drum 23 rotates around the first pipe 2 through the rotation unit. The rotation of the mesh drum 23 can generate centrifugal force, which can not only use the centrifugal force to remove impurities attached to the surface of the mesh drum 23 Out, it can also effectively avoid the attachment of impurities. At the same time, the self-rotation operation of the mesh cylinder 23 can ensure that ozone or ozone water can flow out evenly through the mesh cylinder 23, ensuring the comprehensive contact between the catalyst and ozone or ozone water, ensuring the catalytic effect on it, and at the same time, through the flow unit, the flow stroke of the sewage is increased, ensuring the contact reaction time between the sewage and ozone or ozone water. The first cavity 14 is provided. Due to the characteristics of the ozone itself, it cannot be completely dissolved in the sewage. Therefore, the purified sewage is allowed to enter the first cavity 14, and the undissolved ozone will be discharged through the outlet pipe 16, and then the ozone is purified by the external device (the external device is an ozone destruction device). Device, prior art), and at the same time, when the treatment tube 1 is working, the sewage water level in the treatment tube 1 must be located within the first square cavity 12 to ensure the reaction between the sewage and ozone or ozone water. The treatment tube 1 is provided with an early warning water level monitor 17, which can ensure that the treatment tube 1 is in the best state when working. When the sewage water level is lower than the lowest end of the first square cavity 12, the early warning water level monitor 17 will issue an early warning operation. Only when the sewage water level is within the first square cavity 12 will the early warning water level monitor 17 stop operating and the treatment tube 1 will continue to work. The early warning water level monitor 17 can be combined with a distance sensor and an early warning device. This is prior art and will not be elaborated in detail.

[0036] The rotation unit includes a first gear 25 and a first annular rack 26; one side of the net cylinder 23 is in an open state, and the horizontal tube of the L-shaped tube 21 enters through the opening of the net cylinder 23, and the first gear 25 is fixedly connected to the non-open end wall of the net cylinder 23; a first annular rack 26 is fixedly connected to the side wall of the first cavity 14, and a group of first gears 25 are located outside the first annular rack 26, and the first annular rack 26 and the first gear 25 are meshed with each other;

[0037] The flow unit includes a first cylinder 3 and a second cylinder 31; the first cylinder 3 and the second cylinder 31 are fixedly connected to the side wall of the first cavity 11 close to the first cavity 14; the second cylinder 31 is located in the first cylinder 3; a first auger piece 35 is fixedly connected between the first cylinder 3 and the second cylinder 31; one end of the second cylinder 31 extends into the first cavity 14, and the end of the second cylinder 31 entering the first cavity 14 is in an open state; a group of first through grooves 33 are formed on the end wall of the first cylinder 3 close to the first cavity 14; a conical block 32 is fixedly connected to the inner side wall of the first cylinder 3 away from the first cavity 14, and the end of the conical block 32 extends into the second cylinder 31; a group of second through grooves 34 are formed on the end wall of the second cylinder 31 close to the conical block 32;

[0038] During operation, when the treatment cylinder 1 is working, when the L-shaped tube 21 and the mesh cylinder 23 rotate around the first pipe 2, the first gear 25 and the first annular rack 26 are engaged with each other, which will drive the mesh cylinder 23 to rotate, allowing it to generate centrifugal force, effectively reducing the attachment of impurities while improving the catalytic effect on ozone. At the same time, the process of the sewage and ozone contact reaction is that the sewage enters the first square cavity 12 through the water inlet pipe 13, then enters the first circular cavity 11, and then enters the first cylinder 3 through the first through groove 33. Due to the first auger piece 35, the sewage enters the first square cavity 12 through the water inlet pipe 13, and then enters the first circular cavity 11. The sewage in the first circular cavity 11 is arranged to pass through the first auger piece 35 so as to be in a secondary mixing state, and at the same time flow along the first auger piece 35 to increase the flow stroke. The flowing sewage passing through the first auger piece 35 enters the second cylinder 31 through the second through groove 34, and then enters the first cavity 14 through the second cylinder 31, and finally flows through the outlet pipe 15. In a limited space, the flow stroke of sewage and ozone is increased, thereby increasing the reaction time, ensuring the purification efficiency of sewage, and thus ensuring that the emission standards are met.

[0039] A second auger piece 36 is provided on the outer side wall of the mesh cylinder 23; the second auger pieces 36 on adjacent mesh cylinders 23 have opposite rotation directions; when working, although the rotation directions of the second auger pieces 36 are the same through the power unit, then because the rotation directions of the second auger pieces 36 are opposite, the flow directions of the water flows of the adjacent second auger pieces 36 are opposite, so not only can the water flow be in a turbulent state, further ensuring the mixing effect of sewage and ozone, but also the function of the second auger piece 36 can make the oxidizing particles and hydroxyl free radicals in ozone or ozone water be quickly distributed in the sewage, further improving the efficiency of the oxidation and degradation of organic matter.

[0040] Bristles 4 are fixedly connected to the inner rotating wall of the second auger piece 36, and the bristles 4 are in contact with the outer wall of the net tube 23; a roller 41 is rotatably connected to the horizontal tube of the L-shaped tube 21; the inner rotating wall of the second auger piece 36 is fixedly connected to the outer wall of the roller 41; the roller 41 is rotated by the power unit, and the rotation direction of the roller 41 is opposite to the rotation direction of the net tube 23;

[0041] The power unit includes a second gear 42; a second gear 42 is fixedly connected to the outer wall of the roller 41; a second annular rack 43 is fixedly connected to the annular wall of the first circular cavity 11; a set of second gears 42 is located in the second annular rack 43, and the second annular rack 43 and the second gear 42 are meshed with each other;

[0042] During operation, the roller 41 is connected to the horizontal tube of the L-shaped tube 21 and rotates. When the L-shaped tube 21 rotates around the first pipe 2, the second gear 42 and the second annular rack 43 are engaged with each other, which drives the roller 41 to rotate, thereby rotating the second auger piece 36. The inner rotating wall of the second auger piece 36 and the inside of the net cylinder 23 are not in direct contact, but are in contact through the bristles 4. At the same time, because the second gear 42 is located in the second annular rack 43 and the first gear 25 is located outside the first annular rack 26, the rotation directions of the second auger piece 36 and the net cylinder 23 are opposite, thereby ensuring that the surface of the net cylinder 23 is brushed, further improving the cleaning effect (the rotation speeds of the second auger piece 36 and the net cylinder 23 are also different).

[0043] An annular groove 51 is provided on the side wall of the first circular cavity 11 close to the first cavity 14; the net sleeve 23 is slidably mounted on the horizontal tube of the L-shaped tube 21, and the inner wall of the net sleeve 23 is rotatably connected to a disc 53, and the disc 53 is fixed to the horizontal tube side wall of the L-shaped tube 21 through a spring; a rotating column 5 is rotatably connected to the end of the net sleeve 23; an arc-shaped right-angled trapezoidal block 52 is fixed in the annular groove 51; the rotating column 5 slides in the annular groove 51; the first gear 25 and the first annular rack 26 are both long gears; when working, when the net sleeve 23 rotates around the first pipe 2, the rotating column 5 will slide in In the annular groove 51, the inclined surface of the arc-shaped right-angled trapezoidal block 52 will first push the mesh tube 23 to move, so that the spring in the mesh tube 23 is in a compressed state, and after the rotating column 5 is detached through the right-angled surface of the arc-shaped right-angled trapezoidal block 52, the rotating column 5 and the inner wall of the annular groove 51 will collide with each other, so that the mesh tube 23 will be vibrated. This not only prevents some insoluble organic matter from making the catalyst in a bonding state and affecting the contact area between the catalyst and ozone, but also can make the catalyst slightly shaken out through vibration, thereby ensuring the contact area between the catalyst and ozone. At the same time, the use of slight shaking force can also improve the cleaning of impurities in the catalyst.

[0044] A stirring rod 6 is fixedly connected to the first pipe 2, and the stirring rod 6 is sealed and passes through the first cylinder 3 and the conical block 32 and extends into the second cylinder 31; a group of inner inclined plates 61 are fixedly connected to the outer wall of the stirring rod 6, and a group of inner inclined plates 61 are staggered outside the stirring rod 6; during operation, when the first pipe 2 rotates, it will drive the stirring rod 6 and the inner inclined plates 61 to stir the sewage entering the second cylinder 31, further ensuring the stirring state. The stirring force can also increase the dissolution of ozone (ozone cannot be completely dissolved during the sewage purification process due to solubility and decomposition characteristics), which can always ensure the purification effect of ozone on sewage. At the same time, the setting of the inner inclined plates 61 can break up some impurities to avoid large lumps of condensation that affect the water outlet state through the outlet pipe 15.

[0045] A first groove 71 is provided at the bottom end of the first circular cavity 11; a first inclined surface 72 is provided at the bottom end of the first groove 71; an impurity pipe 7 is provided at a position near the lowest end of the first inclined surface 72 on the side wall of the first groove 71, and the impurity pipe 7 extends out of the treatment cylinder 1; during operation, the first groove 71 is provided at the bottom end of the first circular cavity 11, and some impurities in the sewage purification can be collected through the first groove 71, and then the excess impurities can be discharged through the impurity pipe 7 later, which is also convenient for cleaning the treatment cylinder 1.

[0046] A method for purifying high-concentration industrial organic wastewater, which is applicable to the above-mentioned high-concentration industrial organic wastewater purification device, has the following steps:

[0047] S1: Sewage flows into the first circular cavity 11 through the first square cavity 12 via the water inlet pipe 13;

[0048] S2: At the same time, ozone or ozone water enters the L-shaped tube 21 through the first pipe 2, then enters the mesh tube 23 through the first through-hole 22, and then passes through the catalyst in the mesh tube 23 to enter the first circular cavity 11. Through the action of the catalyst, ozone is more effectively decomposed to produce hydroxyl radicals, a strong oxidant, thereby accelerating the oxidative decomposition of organic matter;

[0049] S3: The rotation of the first pipe 2 will drive a group of L-shaped tubes 21 and the mesh tube 23 to rotate, thereby putting the water flow in a stirring state, which can effectively allow the ozone or ozone water to quickly mix and contact with the sewage. At the same time, the mesh tube 23 rotates around the first pipe 2 through the rotation unit. At the same time, the flow unit increases the flow distance of the sewage, thereby ensuring the contact reaction time between the sewage and ozone or ozone water.

[0050] Working principle: Sewage will flow into the first circular cavity 11 through the water inlet pipe 13 and the first square cavity 12. At the same time, ozone or ozone water will enter the L-shaped tube 21 through the first through hole 22, and then enter the mesh tube 23 through the first through hole 22. Then, it will enter the first circular cavity 11 through the catalyst in the mesh tube 23. Through the action of the catalyst, ozone will be more effectively decomposed to produce hydroxyl free radicals, a strong oxidant, thereby accelerating the oxidation and decomposition of organic matter. The servo motor 24 drives the first pipe 2 to rotate through gear meshing, which will drive a group of L-shaped The pipe 21 and the mesh drum 23 rotate, thereby making the water flow in a stirring state, which can effectively allow ozone or ozone water to quickly mix and contact with sewage. At the same time, the mesh drum 23 rotates around the first pipe 2 through the rotation unit. The rotation of the mesh drum 23 can generate centrifugal force, which can not only use the centrifugal force to throw out impurities attached to the surface of the mesh drum 23, but also effectively avoid the attachment of impurities. At the same time, the rotation operation of the mesh drum 23 can ensure that ozone or ozone water can pass through the mesh drum evenly. The net tube 23 is used for outflow, ensuring the comprehensive contact between the catalyst and ozone or ozone water, ensuring the catalytic effect on them, and at the same time, through the flow unit, the flow stroke of the sewage is increased, ensuring the contact reaction time between the sewage and ozone or ozone water, and there is a first cavity 14. Due to the characteristics of the ozone itself, it cannot be completely dissolved in the sewage, so the purified sewage is allowed to enter the first cavity 14, and the undissolved ozone will be discharged through the outlet pipe 16, and then the ozone is purified by an external device (the external device is an ozone destroyer, Existing technology), while the treatment tube 1 is working, the sewage water level in the treatment tube 1 must be located within the first square cavity 12 to ensure the reaction between the sewage and the ozone or ozone water. The treatment tube 1 is provided with an early warning water level monitor 17, which can ensure that the treatment tube 1 is in the best state during operation. When the sewage water level is lower than the lowest end of the first square cavity 12, the early warning water level monitor 17 will start an early warning operation. Only when the sewage water level is within the first square cavity 12 will the early warning water level monitor 17 stop operating, and the treatment tube 1 can continue to work;When the treatment cylinder 1 is working, when the L-shaped tube 21 and the mesh cylinder 23 rotate around the first pipe 2, the first gear 25 and the first annular rack 26 are engaged with each other, which will drive the mesh cylinder 23 to rotate, so that it generates centrifugal force, effectively reducing the attachment of impurities while improving the catalytic effect on ozone. At the same time, the contact reaction between sewage and ozone is as follows: the sewage enters the first square cavity 12 through the water inlet pipe 13, then enters the first circular cavity 11, and then enters the first cylinder 3 through the first through groove 33. Due to the setting of the first auger piece 35, the sewage enters the first square cavity 12 through the water inlet pipe 13, and then enters the first circular cavity 11. The sewage in the first circular cavity 11 is allowed to pass through the first auger piece 35 to enter a secondary mixing state. Simultaneously, it flows along the first auger piece 35, increasing the flow distance. The sewage flowing through the first auger piece 35 enters the second cylinder 31 through the second through-channel 34, then passes through the second cylinder 31 into the first cavity 14, and finally flows through the outlet pipe 15.
