Description

Technical Field

[0001] The 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 the industrial production process with a chemical oxygen demand (COD) significantly higher than that of conventional wastewater. Its core characteristics are as follows: Concentration threshold: In the internationally accepted standards, the COD concentration is usually ≥2000mg / L; some industries (such as chemical and pharmaceutical industries) have higher definition standards, COD ≥3000mg / 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.) 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, a continuous treatment method is usually used to treat a large amount of sewage. However, for the treatment of organic wastewater, ozone or ozone water needs to be introduced to directly decompose the organic matter in the wastewater by using its strong oxidizing property. In the continuous treatment process, in order to ensure the oxidation and 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 byproducts produced by oxidation and 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 to ozone or ozone water, but also significantly reduces the oxidation and degradation efficiency of organic matter in organic wastewater.

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1 to 10As shown in the figure, a purification and treatment device for high-concentration industrial organic wastewater according to an embodiment of the present invention includes a treatment cylinder 1; a first circular cavity 11 is provided in the treatment cylinder 1; a first square cavity 12 is provided at the top of the first circular cavity 11; a first cavity 14 is provided in the treatment cylinder 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 a position of the top of the treatment cylinder 1 away from the first cavity 14, and the water inlet pipe 13 is interconnected with the first square cavity 12; a water outlet pipe 15 is fixedly connected to the side wall of the first cavity 14, and the water outlet pipe 15 is interconnected with the first cavity 14; an air outlet pipe 16 is provided at the top of the first cavity 14; a first pipe 2 is rotatably connected to the middle of the treatment cylinder 1; a group of L-shaped pipes 21 are fixedly connected to the end wall of the first pipe 2 extending into the first circular cavity 11, and the first pipe 2 is interconnected with the L-shaped pipes 21; a sleeve net cylinder 23 is sleeved on the horizontal pipe of the L-shaped pipe 21; a first through hole 22 is provided on the outer side wall of the horizontal pipe of the L-shaped pipe 21; a catalyst material is placed in the sleeve net cylinder 23; the sleeve net cylinder 23 rotates through a self-rotation unit; a servo motor 24 is fixedly connected to the side wall of the treatment cylinder 1 through a connecting rod, and the servo motor 24 drives the first pipe 2 to rotate through gear meshing; a warning water surface monitor 17 is provided at the top of the treatment cylinder 1; in the current technical field, a continuous treatment method is usually adopted to treat a large amount of sewage. However, for the treatment of organic wastewater, ozone or ozone water needs to be introduced, and its strong oxidizing property is used to directly decompose the organic matter in the wastewater. In the continuous treatment process, in order to ensure the oxidative degradation of the organic matter, it is necessary to ensure that the wastewater has sufficient reaction time with ozone or ozone water.Therefore, existing processing devices are often too long, resulting in a large occupied space. At the same time, during long-term continuous reactions, due to the characteristics of the sewage components, by-products generated by oxidative degradation, and products of incomplete degradation of organic matter, some solid impurities will accumulate on the surface of the catalyst. This not only affects the catalytic efficiency of the catalyst for ozone or ozone water but also significantly reduces the oxidative degradation efficiency of organic matter in organic wastewater. Therefore, when the present invention is working, sewage will flow into the first circular cavity 11 through the first square cavity 12 via the water inlet pipe 13. At the same time, ozone or ozone water enters the L-shaped pipe 21 through the first pipe 2, then enters the sleeve net cylinder 23 through the first through hole 22, passes through the catalyst in the sleeve net cylinder 23, enters the first circular cavity 11. Through the action of the catalyst, ozone can be more effectively decomposed to generate strong oxidants such as hydroxyl radicals, thereby accelerating the oxidative decomposition of organic matter. The servo motor 24 drives the rotation of the first pipe 2 through gear meshing, which will drive a group of L-shaped pipes 21 and sleeve net cylinders 23 to rotate, thereby making the water flow in a stirred state, enabling ozone or ozone water to quickly mix and contact with the sewage effectively. At the same time, the sleeve net cylinder 23 performs a self-rotation operation through the self-rotation unit while rotating around the first pipe 2. The self-rotation of the sleeve net cylinder 23 can generate a centrifugal force, which can not only use the centrifugal force to throw out the impurities attached to the surface of the sleeve net cylinder 23 but also effectively avoid the attachment of impurities. At the same time, the self-rotation operation of the sleeve net cylinder 23 can ensure that ozone or ozone water can uniformly flow out through the sleeve net cylinder 23, ensuring the comprehensiveness of the contact between the catalyst and ozone or ozone water and ensuring its catalytic effect. At the same time, through the flow unit, the flow path of the sewage is increased, ensuring the contact reaction time between the sewage and ozone or ozone water. In the first cavity 14, due to the characteristics of ozone itself, it cannot be completely dissolved in the sewage. Therefore, the purified sewage enters the first cavity 14, and the undissolved ozone will exit through the air outlet pipe 16 and then be purified by an external device (the external device is an ozone destructor, prior art). At the same time, when the treatment cylinder 1 is working, the water surface of the sewage in the treatment cylinder 1 should be located in the first square cavity 12 to ensure the reaction between the sewage and ozone or ozone water. A warning water surface monitor 17 is provided on the treatment cylinder 1, which can ensure that the treatment cylinder 1 is in the best state during operation. When the water surface of the sewage is lower than the lowest end of the first square cavity 12, the warning water surface monitor 17 will give a warning operation. Only when the water surface of the sewage is located in the first square cavity 12, the warning water surface monitor 17 will stop operating, and then the treatment cylinder 1 will work. The warning water surface monitor 17 can be combined with a distance sensor and a warning device, which is prior art and will not be elaborated in detail.

[0023] The rotation unit includes a first gear 25 and a first annular rack 26; one side of the sleeve net cylinder 23 is in an open state, the horizontal pipe of the L-shaped pipe 21 enters through the opening of the sleeve net cylinder 23, and the first gear 25 is fixedly connected to the non-opening end wall of the sleeve net cylinder 23; the first annular rack 26 is fixedly connected to the side wall of the first cavity 14, and a set 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; The flow unit includes a first cylinder 3 and a second cylinder 31; the first circular cavity 11 is fixedly connected with a first cylinder 3 and a second cylinder 31 on the side wall close to the first cavity 14; the second cylinder 31 is located inside the first cylinder 3; a first auger blade 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 set of first through grooves 33 are opened 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 far from the first cavity 14, and the end of the conical block 32 extends into the second cylinder 31; a set of second through grooves 34 are opened on the end wall of the second cylinder 31 close to the conical block 32; During operation, when the treatment cylinder 1 is working, when the L-shaped pipe 21 and the sleeve net cylinder 23 rotate around the first pipe 2, due to the meshing of the first gear 25 and the first annular rack 26, the rotation of the sleeve net cylinder 23 will be driven, generating centrifugal force, effectively reducing the attachment of impurities and improving the catalytic effect on ozone. At the same time, the travel 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 grooves 33. Due to the arrangement of the first auger blade 35, the sewage in the first circular cavity 11 is in a secondary mixing state through the first auger blade 35 and flows along the first auger blade 35, increasing the flow travel. The sewage flowing through the first auger blade 35 enters the second cylinder 31 through the second through grooves 34, then enters the first cavity 14 through the second cylinder 31, and finally flows through the water outlet pipe 15. In a limited space, the flow travel of the sewage and ozone is increased, thereby increasing the reaction time, ensuring the purification efficiency of the sewage, and thus ensuring compliance with the discharge standard.

[0024] A second auger blade 36 is provided on the outer side wall of the sleeve net cylinder 23; the rotation directions of the second auger blades 36 on adjacent sleeve net cylinders 23 are opposite; during operation, although the power unit makes the rotation directions of the second auger blades 36 the same, due to the opposite rotation directions of the second auger blades 36, the flow directions of the water flow for adjacent second auger blades 36 are opposite. Therefore, not only can the water flow be in a turbulent state, further ensuring the mixing effect of sewage and ozone, but also the second auger blade 36 can make the oxidation particles and hydroxyl free radicals in ozone or ozone water be quickly distributed in the sewage, further improving the oxidation and degradation efficiency of organic matter.

[0025] A brush 4 is fixedly connected to the inner rotating wall of the second auger blade 36, and the brush 4 is in contact with the outer side wall of the sleeve net cylinder 23; a roller 41 is rotatably connected to the horizontal pipe of the L-shaped pipe 21; the inner rotating wall of the second auger blade 36 is fixedly connected to the roller 41; the roller 41 rotates through a power unit, and the rotation direction of the roller 41 is opposite to the rotation direction of the sleeve net cylinder 23. The power unit includes a second gear 42; the second gear 42 is fixedly connected to the outer side wall of the roller 41; the second annular rack 43 is fixedly connected to the annular wall of the first circular cavity 11; a group of the second gears 42 are located in the second annular rack 43, and the second annular rack 43 meshes with the second gear 42. During operation, the roller 41 is rotatably connected to the horizontal pipe of the L-shaped pipe 21. When the L-shaped pipe 21 rotates around the first pipe 2, since the second gear 42 and the second annular rack 43 mesh with each other, it will drive the roller 41 to rotate, thereby making the second auger blade 36 rotate. Moreover, the inner rotating wall of the second auger blade 36 does not directly contact the inside of the sleeve net cylinder 23, but contacts through the brush 4. At the same time, since 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 blade 36 and the sleeve net cylinder 23 are opposite, thereby ensuring brushing the surface of the sleeve net cylinder 23 and further improving the cleaning effect (where the rotation speeds of the second auger blade 36 and the sleeve net cylinder 23 are also different).

[0026] An annular groove 51 is formed in the side wall of the first circular cavity 11 close to the first cavity 14; the sleeve net cylinder 23 is sleeved and slid on the horizontal pipe of the L-shaped pipe 21, the inner wall of the sleeve net cylinder 23 is rotatably connected with a disc 53, and the disc 53 is fixedly connected to the side wall of the horizontal pipe of the L-shaped pipe 21 through a spring; a rotating column 5 is rotatably connected to the end of the sleeve net cylinder 23; the arc-shaped right trapezoidal block 52 is fixedly connected in the annular groove 51; the rotating column 5 slides in the annular groove 51; both the first gear 25 and the first annular rack 26 are long gears; during operation, when the sleeve net cylinder 23 rotates around the first pipe 2, the rotating column 5 will slide in the annular groove 51, and then first push the sleeve net cylinder 23 to move through the inclined surface of the arc-shaped right trapezoidal block 52, so that the spring in the sleeve net cylinder 23 is in a compressed state. After the rotating column 5 disengages from the right-angle surface of the arc-shaped right trapezoidal block 52, the rotating column 5 collides with the inner wall of the annular groove 51, causing the sleeve net cylinder 23 to vibrate. This not only prevents some insoluble organic substances from bonding the catalyst, affecting the contact area between the catalyst and ozone, but also enables the catalyst to be slightly shaken and dispersed through vibration, ensuring the contact area between the catalyst and ozone. At the same time, using the slight shaking force can also improve the cleaning of impurities on the catalyst.

[0027] A stirring rod 6 is fixedly connected to the first pipe 2, and the stirring rod 6 penetrates through the first cylinder 3 and the conical block 32 in a sealed manner and extends into the second cylinder 31; a group of inner inclined plates 61 are fixedly connected to the outer side wall of the stirring rod 6, and the group of inner inclined plates 61 are staggered on the outer side of 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. Using the stirring force can also increase the dissolution of ozone (ozone cannot be completely dissolved due to solubility and decomposition characteristics during the sewage purification process), and can always ensure the purification effect of ozone on the sewage. At the same time, the setting of the inner inclined plates 61 can break some impurities to prevent large lumps from forming and affecting the water outlet state through the water outlet pipe 15.

[0028] A first groove 71 is formed at the bottom end of the first circular cavity 11; a first inclined surface 72 is formed at the bottom end of the first groove 71; an impurity pipe 7 is formed at a position on the side wall of the first groove 71 close to the lowest end of the first inclined surface 72, and the impurity pipe 7 extends out of the treatment cylinder 1; during operation, a first groove 71 is formed 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 excessive impurities can be discharged through the impurity pipe 7 subsequently, which also facilitates the cleaning of the treatment cylinder 1.

[0029] A method for purifying and treating high-concentration industrial organic wastewater, which is applicable to the above-mentioned high-concentration industrial organic wastewater purification and treatment device, and the steps are as follows: S1: Sewage will flow into the first circular cavity 11 through the first square cavity 12 via the water inlet pipe 13; S2: Meanwhile, ozone or ozone water enters the L-shaped pipe 21 through the first pipe 2, then enters the sleeve net cylinder 23 through the first through hole 22, passes through the catalyst in the sleeve net cylinder 23, and enters the first circular cavity 11. Through the action of the catalyst, ozone can be more effectively decomposed to generate strong oxidants such as hydroxyl radicals, thereby accelerating the oxidation and decomposition of organic substances; S3: When the first pipe 2 rotates, it will drive a group of L-shaped pipes 21 and sleeve net cylinders 23 to rotate, thus making the water flow in a stirred state, enabling ozone or ozone water to quickly mix and contact with the sewage effectively. At the same time, the sleeve net cylinder 23 rotates through the rotation unit while rotating around the first pipe 2, and through the flow unit, the flow path of the sewage is increased to ensure the contact reaction time between the sewage and ozone or ozone water.

[0030] Working principle: Sewage will flow into the first circular cavity 11 through the first square cavity 12 via the water inlet pipe 13. At the same time, ozone or ozone water will enter the L-shaped pipe 21 through the first pipe 2, then enter the sleeve net cylinder 23 through the first through hole 22, pass through the catalyst in the sleeve net cylinder 23, and enter the first circular cavity 11. Through the action of the catalyst, ozone can more effectively decompose to generate strong oxidants such as hydroxyl radicals, thereby accelerating the oxidation and decomposition of organic substances. The servo motor 24 drives the rotation of the first pipe 2 through gear meshing, which will drive a group of L-shaped pipes 21 and sleeve net cylinders 23 to rotate, thus making the water flow in a stirred state, enabling ozone or ozone water to quickly mix and contact with the sewage effectively. At the same time, the sleeve net cylinder 23 performs a self-rotation operation through the self-rotation unit while rotating around the first pipe 2. The self-rotation of the sleeve net cylinder 23 can generate centrifugal force, which can not only use the centrifugal force to eject the impurities adhering to the surface of the sleeve net cylinder 23 but also effectively avoid the adhesion of impurities. At the same time, the self-rotation operation of the sleeve net cylinder 23 can ensure that ozone or ozone water can uniformly flow out through the sleeve net cylinder 23, ensuring the comprehensiveness of the contact between the catalyst and ozone or ozone water and ensuring its catalytic effect. At the same time, through the flow unit, the flow path of the sewage is increased, ensuring the contact reaction time between the sewage and ozone or ozone water. In the first cavity 14, due to the characteristics of ozone itself, it cannot be completely dissolved in the sewage. Therefore, the purified sewage enters the first cavity 14, and the undissolved ozone will exit through the air outlet pipe 16 and then be purified by an external device (the external device is an ozone destructor, prior art). At the same time, when the treatment cylinder 1 is working, the water surface of the sewage in the treatment cylinder 1 should be located in the first square cavity 12 to ensure the reaction between the sewage and ozone or ozone water. A warning water surface monitor 17 is provided on the treatment cylinder 1, which can ensure that the treatment cylinder 1 is in the best state during operation. When the water surface of the sewage is lower than the lowest end of the first square cavity 12, the warning water surface monitor 17 will give a warning operation. Only when the water surface of the sewage is located in the first square cavity 12, the warning water surface monitor 17 will stop operating, and then the treatment cylinder 1 will work;When the processing cylinder 1 is working, when the L-shaped pipe 21 and the sleeve net cylinder 23 rotate around the first pipe 2, due to the meshing of the first gear 25 and the first annular rack 26, the self-rotation of the sleeve net cylinder 23 will be driven, generating a centrifugal force, effectively reducing the attachment of impurities and improving the catalytic effect on ozone. At the same time, the travel 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 setting of the first auger blade 35, the sewage in the first circular cavity 11 is in a secondary mixing state through the first auger blade 35 and flows along the first auger blade 35, increasing the flow travel. The sewage flowing through the first auger blade 35 enters the second cylinder 31 through the second through groove 34, then enters the first cavity 14 through the second cylinder 31, and finally flows through the water outlet pipe 15.
