Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, in particular to an ozone catalytic oxidizer for sewage treatment and a treatment process thereof. Background Art

[0002] Wastewater ozone oxidation is a treatment method that uses ozone as a strong oxidant to oxidize organic and inorganic matter in water or wastewater. The main purpose of this method is to remove pollutants in the water, including COD, BOD, phenol, cyanide, iron, manganese, etc., and to achieve deodorization, decolorization, sterilization and disinfection.

[0003] In the prior art, the use of ozone catalytic oxidizers has the following problems: the ozone catalytic oxidizer itself does not directly produce solid impurities, but in actual operation, the water after ozone catalytic oxidation treatment will change its physical and chemical properties due to the degradation and oxidation of organic matter, thereby affecting the behavior of particulate matter or suspended matter in the water, causing it to form sediment. Although it can further purify the sewage quality, the ozone catalytic oxidation reaction is carried out in a closed environment. The sediment or suspended matter generated in the device requires secondary filtration and other operations to ensure the effluent water quality requirements. The sewage treatment steps increase, and solid impurities are easy to adhere to the ozone catalytic oxidizer and are difficult to remove, affecting the sewage treatment efficiency.

DETAILED DESCRIPTION

[0033] 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.

[0034] like Figures 1 to 10As shown, an ozone catalytic oxidizer for sewage treatment described in an embodiment of the present invention includes a tank body 1, which includes a tank base 11 and a tank cover barrel 12. The bottom end of the tank cover barrel 12 is installed on the tank base 11. A circular groove 26 is provided in the middle of the tank base 11. The cross-section of the circular groove 26 is an inverted T-shaped. A conical block 27 is rotatably connected to the side wall of the opening of the circular groove 26. The top of the conical block 27 is a flat end. The center line of the conical block 27 coincides with the center line of the tank base 11. A water outlet pipe 3 is provided at the bottom of the tank base 11, an air outlet pipe 33 and a discharge pipe 32 are provided at the top of the tank cover barrel 12, a water inlet pipe 31 is provided on the outer wall of the tank cover barrel 12, an annular groove 13 is provided on the outer wall of the tank cover barrel 12, the water inlet pipe 31 is located below the annular groove 13, a group of support columns 14 are fixedly connected in the annular groove 13, and the outer wall of the tank cover barrel 12 An annular collecting cylinder 15 is fixedly connected to the top, and the annular collecting cylinder 15 covers the annular through groove 13. A miscellaneous pipe is provided at the end of the annular collecting cylinder 15. The top of the tank cover barrel 12 is fixedly connected to the first motor 2 through an L-shaped rod. The top of the conical block 27 is rotatably connected to the screw 21. The top of the screw 21 passes through the tank cover barrel 12 and is detachably mounted on the output end of the first motor 2. A round block 22 is connected to the screw 21 through a screw nut pair. An annular block 23 is rotatably connected to the outer wall of the round block 22. A circular dense mesh disk 24 is fixedly connected to the outer wall of the annular block 23. The circular dense mesh disk 24 is attached to the bottom surface of the tank base 11. A pair of guide columns 25 are fixedly connected to the middle part of the top of the tank cover barrel 12. The guide columns 25 pass through the round block 22. The conical block 27 drives the circular dense mesh disk 24 to rotate through a power piece. An inflation unit is provided on the tank base 11.During operation, sewage enters the tank body 1 through the water inlet pipe 31, and an ozone catalyst is placed in the discharge pipe 32. During the sewage ozone catalytic reaction, ozone is filled into the sewage through the inflation unit. Under the catalysis of the ozone catalyst, sewage treatment is carried out. At this time, the circular dense mesh disk 24 (which can pass through the water flow) is attached to the bottom surface of the tank base 11, and the sediment generated in the tank body 1 is located above the circular dense mesh disk 24. At the same time, the power piece drives the conical block 27 and the circular dense mesh disk 24 to rotate, so that the water The flow is in a stirring state. After the sewage treatment is completed, the first motor 2 is started at the same time as the water is discharged from the outlet pipe 3. The first motor 2 drives the screw 21 to rotate. The rotation of the screw 21 drives the round block 22 to move upward. The upward movement of the round block 22 drives the annular block 23 and the circular dense mesh disk 24 to move upward. In the process of the circular dense mesh disk 24 moving upward, the sediment and other solid impurities in the sewage are filtered. When the circular dense mesh disk 24 is at the top, it is just at the position of the annular groove 13. At this time, the power part drives the conical block 2 again. 7 and the circular dense mesh disk 24 rotate (the annular block 23 and the circular block 22 are rotatably connected, and the rotation of the circular dense mesh disk 24 does not affect the state of the circular block 22). Centrifugal force is used to throw the filtered impurities and ozone solid catalyst through the annular groove 13 into the annular collection cylinder 15. The solid impurities and ozone solid catalyst are collected by the annular collection cylinder 15 (the ozone solid catalyst is subsequently cleaned separately). The above operation is repeated again to complete the non-stop impurity treatment of the ozone catalytic reactor, avoid secondary filtration operations, ensure the quality of the effluent, and improve the efficiency of sewage treatment. Valves are provided on the outlet pipe 3, the inlet pipe 31, the discharge pipe 32, and the outlet pipe 33. The annular collection cylinder 15 is also provided with a discharge pipe to facilitate the collection of impurities and materials. The output end of the first motor 2 and the lead screw 21 are detachably connected, and can adopt a pin-lock connection or a chuck connection. The circular dense mesh disk 24 is a dense filter mesh that can pass water. At the same time, the circular dense mesh disk 24 has a hard skeleton and will not deform.

[0035] The power part includes a rotating column 28, and a group of rotating columns 28 are rotatably connected on the conical surface of the conical block 27. The rotating column 28 passes through the circular dense mesh disk 24, and a second motor 29 is fixedly connected to the middle of the tank base 11. The output end of the second motor 29 is connected to the second rotating shaft 291, and the second rotating shaft 291 extends into the circular groove 26 and is fixedly connected to the bottom end of the conical block 27. An annular rubber layer is provided on the outer wall of the circular dense mesh disk 24, and the circular dense mesh disk 24 slides on the inner wall of the tank cover barrel 12. A push plate 46 is fixedly connected to the circular dense mesh disk 24, and an annular baffle 45 is connected to the inner wall of the tank cover barrel 12 for sliding up and down. The annular baffle 45 covers the annular groove 13; when sewage is treated, the second motor 29 is started, the conical block 27 and the circular dense mesh disk 24 rotate, and the second motor The machine 29 drives the conical block 27 to rotate through the second rotating shaft 291, and the rotation of the conical block 27 drives the rotating column 28 to rotate around the second rotating shaft 291. The rotating column 28 penetrates the circular dense mesh disk 24. Therefore, when the rotating column 28 rotates around the second rotating shaft 291, it will drive the annular block 23 on the circular dense mesh disk 24 to rotate around the circular block 22, thereby increasing the mixing efficiency of the sewage. After the sewage treatment is completed, when the circular dense mesh disk 24 rises to the highest point (without separating from the rotating column 28), centrifugal force is used to remove the material. At this time, the circular through groove 63 is blocked by the annular baffle 45 to prevent the sewage from being discharged through the annular through groove 13 during mixing. When the circular dense mesh disk 24 rises, the push plate 46 is used to push the annular baffle 45 upward to open the circular through groove 63 and complete the collection of impurities.

[0036] The inflation unit includes an annular concave plate 4, which is fixedly connected to the annular concave plate 4 on the bottom of the circular groove 26, and an annular cover plate 41 is rotatably connected to the top of the annular concave plate 4. The bottom end of the rotating column 28 extends into the circular groove 26 and is rotatably connected to the annular cover plate 41. A group of ventilation chambers 42 are opened in the rotating column 28, and the bottom end of the ventilation chamber 42 and the inner cavity of the annular concave plate 4 are communicated with each other. An air inlet pipe 43 is fixedly connected to the tank base 11, and the air inlet pipe 43 is communicated with the inner cavity of the annular concave plate 4. A group of air outlet holes 44 are opened on the outer wall of the rotating column 28, and the air outlet holes 44 and the air outlet holes 44 are communicated with each other; when sewage is treated, ozone is filled in through the air inlet pipe 43, and the ozone gas passes through the annular concave plate 4 and the ventilation chamber 42 and is ejected from the air outlet holes 44. The air outlet holes 44 are located on the outer wall of the rotating column 28. When the rotating column 28 rotates around the second rotating shaft 291 and the screw 21, the uniformity of ozone filling is ensured, the full utilization of ozone is ensured, and a large amount of ozone overflow is avoided.

[0037] A group of first cross grooves 5 are provided in the column body of the rotating column 28 which is higher than the conical block 27. The middle part of the first cross groove 5 is circular. Adjacent side walls of the first cross groove 5 are rotatably connected with stirring plates 51 through a rotating shaft. The outer and inner walls of the stirring plates 51 are arc-shaped. The stirring plates 51 are opened or closed by an opening member. When working, the stirring plates 51 are bounded by the rotating shaft, and are shorter at the top and longer at the bottom. During sewage treatment, the circular dense mesh disk 24 is attached to the bottom surface of the tank base 11. At this time, the stirring plates 51 are in an unfixed state. When the rotating column 28 rotates around the second rotating shaft 291 and the lead screw 21, the rotating column 28 rotates through the self-rotation operation of the opening member, and the rotating column 28 drives the stirring plates 51 to process the open state, so that local turbulence of the sewage is generated. At the same time, ozone is filled into the rotating column 28 to avoid the generation of bubbles, further increase the stirring force, and ensure the reaction efficiency.

[0038] The opening part includes an annular spur gear 52 and a closing unit. The annular spur gear 52 is fixedly connected to the bottom of the circular groove 26. The rotating column 28 is located on the shaft wall in the circular groove 26 and is provided with a first gear 53. The first gear 53 and the annular spur gear 52 are engaged with each other. During operation, when the conical block 27 rotates, the rotating column 28 rotates around the second rotating axis 291 and the screw 21, and the first gear 53 and the annular spur gear 52 rotate because the rotating column 28 rotates while revolving.

[0039] The closing unit includes a second cross groove 56, and the rotating column 28 is provided with a second cross groove 56 in the column body of the circular groove 26. The rotating column 28 is located on the column wall of the circular groove 26 and is slidably sleeved with a lower pressure plate 57. The lower pressure plate 57 is slidably connected to the inner wall of the second cross groove 56. The top of the first cross groove 5 is fixedly connected to a circular plate 54 by a spring. The circular plate 54 is connected by a connecting rod 55. The connecting rod 55 passes through the rotating column 28 and is fixedly connected to the middle of the lower pressure plate 57. The lower pressure plate 57 is rotatably connected to the first annular plate 58, and the first annular plate 58 is fixedly connected to the lower pressure column 59. The top of the lower pressure column 59 passes through the conical block 27. When working, the circular dense mesh disk 24 is on the bottom surface of the tank base 11. When the circular plate 54 moves upward, the lower pressure column 59, the lower pressure plate 57, the lower pressure plate 57 drives the circular plate 54 to move downward through the connecting rod 55, which will not affect the opening of the stirring plate 51 under the action of the centrifugal force of the rotating column 28, but the stirring plate 51 is in the open state. When the rotating column 28 stops revolving and rotating, the stirring plate 51 will not be completely retracted under the action of the water flow. Therefore, a circular plate 54 is provided. When the circular dense mesh disk 24 moves upward, the lower pressure column 59, the lower pressure plate 57, the connecting rod 55 and the circular plate 54 all move upward. The upward movement of the circular plate 54 pushes the stirring plate 51 to close. When the outer wall of the circular plate 54 and the inner arc wall of the stirring plate 51 are completely fitted together, the stirring plate 51 is in a closed state, which will not affect the upward movement of the circular dense mesh disk 24.

[0040] An arc-shaped cavity 6 is provided in the stirring plate 51, and a group of spherical catalysts 62 are placed in the arc-shaped cavity 6. A group of first through grooves 61 are provided on the outer wall of the stirring plate 51, and the first through grooves 61 and the arc-shaped cavity 6 are interconnected. A circular through groove 63 is provided on the stirring plate 51, and the circular through groove 63 and the arc-shaped cavity 6 are interconnected. When working, the ozone solid catalyst is solid, and the catalyst theoretically will not be lost in the sewage. The ozone solid catalyst is generally deposited at the bottom of the tank body 1, and the reaction to the upper sewage is not uniform. Therefore, a group of spherical catalysts 62 are provided in the arc-shaped cavity 6 of the stirring plate 51, and the water flows through the first through groove 63. The through groove 61 is immersed, and when the ozone gas is released by rotating the rotating column 28, the spherical catalyst 62 is used to catalyze the reaction at the first time to further improve the catalytic efficiency. The ozone solid catalyst discharged through the discharge pipe 32 still needs to be added. Theoretically, the spherical catalyst 62 will not be lost, but in actual operation, there are impurities or wear on the spherical catalyst 62, so the tank cover barrel 12 is removed from the tank base 11, and the output end of the first motor 2 is removed from the screw 21, so that the tank cover barrel 12 and the tank base 11 are separated, and the spherical catalyst 62 is taken out and replaced through the circular through groove 63, and the circular dense mesh disk 24 is cleaned at the same time.

[0041] The rotating column 28 is located on the outer side wall of the cylindrical body of the circular groove 26 and an annular groove 7 is opened. The bottom end of the annular groove 7 is provided with a pair of arc grooves 71 symmetrical about the center of the rotating column 28. A pair of sliders 72 are fixedly connected to the inner wall of the first gear 53. The sliders 72 are located in the arc grooves 71. The bottom end of the lower pressure plate 57 is rotatably connected to the second annular plate 74. The bottom end of the second annular plate 74 is fixedly connected to a pair of symmetrically distributed elastic telescopic rods 73. The bottom end of the elastic telescopic rod 73 is fixedly connected to the top of the first gear 53. During operation, when the circular dense mesh disk 24 moves to the highest point, the circular dense mesh disk 24 rotates to throw the impurity material to the outer ring wall. At this time, the rotating column 28 does not need to rotate on its own, but only needs to revolve to complete the circular dense mesh disk 2 4 is a material-throwing operation. At this time, the rotating column 28 is prevented from rotating on its own and affecting the expansion of the stirring plate 51. Therefore, when the lower pressure plate 57 moves up, the first gear 53 is driven to move up, allowing the slider 72 to enter the annular groove 7 from the arc groove 71. At this time, the rotation of the first gear 53 will not drive the rotating column 28 to rotate. When the circular dense mesh disk 24 is subsequently attached to the bottom surface of the tank base 11, the lower pressure column 59 presses down the lower pressure plate 57, and presses down the first gear 53 through the elastic telescopic rod 73. When the first gear 53 rotates, the slider 72 is pressed into the arc groove 71 through the elastic telescopic rod 73, and then the first gear 53 rotates to drive the rotating column 28 to rotate, completing the rotation of the rotating column 28 (wherein the annular spur gear 52 and the first gear 53 are always in a meshing state).

[0042] A third annular plate 8 is fixedly connected to the inner wall of the top of the tank cover barrel 12, and a group of first grooves 81 are opened at the bottom of the third annular plate 8. A connecting chute 82 is opened on the side wall of the first groove 81. A vibration rod 83 is fixedly connected to the bottom of the first groove 81 through a spring. A vibration ball 84 is fixedly connected to the bottom of the vibration rod 83. A sliding rod 88 is fixedly connected to the rod wall of the vibration rod 83. The sliding rod 88 extends out of the first groove 81 through the connecting chute 82. An annular disk 85 is provided on the inner wall of the third annular plate 8. The outer wall of the annular disk 85 is fixedly connected to the sliding rod 88. The bottom end of the annular disk 85 is fixedly connected. A group of semicircular balls 87 are fixedly connected, and the semicircular balls 87 have a semicircular structure. An L-shaped column 86 is fixedly connected to the outer wall of the annular block 23; during operation, when the circular dense mesh disk 24 moves to the highest point, the top of the L-shaped column 86 corresponds to the bottom of the semicircular ball 87, and the circular dense mesh disk 24 rotates, driving the annular block 23 to rotate. The rotation of the annular block 23 drives the L-shaped column 86 to rotate. The L-shaped column 86 rotates and drives the annular disk 85 to cycle up and down through the semicircular balls 87, thereby driving the vibrating ball 84 of the vibrating rod 83 to operate up and down, vibrating the circular dense mesh disk 24 to facilitate the falling of impurities.

[0043] A treatment process for sewage treatment using an ozone catalytic oxidizer comprises the following steps:

[0044] S1: Sewage enters the tank body 1 through the water inlet pipe 31, and then an ozone catalyst is placed in the discharge pipe 32. When the sewage undergoes an ozone catalytic reaction, ozone is injected into the sewage through the aeration unit. Under the catalysis of the ozone catalyst, the sewage is treated. At this time, the circular dense mesh disk 24 is attached to the bottom surface of the tank base 11;

[0045] S2: The conical block 27 and the circular dense mesh disk 24 are driven to rotate by the power member to keep the water in a stirring state. After the sewage treatment is completed, the water is discharged through the outlet pipe 3 and the first motor 2 is started. The first motor 2 drives the lead screw 21 to rotate, and when the circular dense mesh disk 24 moves to the top, it is exactly located at the position of the annular groove 13;

[0046] S3: The power member drives the conical block 27 and the circular dense mesh disk 24 to rotate again, and uses centrifugal force to throw the filtered impurities and ozone solid catalyst into the annular collecting cylinder 15 through the annular groove 13, and the solid impurities and ozone solid catalyst are collected by the annular collecting cylinder 15.

[0047] Principle: Sewage enters the tank body 1 through the water inlet pipe 31, and an ozone catalyst is placed in the discharge pipe 32. When the sewage ozone catalytic reaction occurs, ozone is filled into the sewage through the inflation unit to carry out sewage catalytic treatment. At this time, the circular dense mesh disk 24 is attached to the bottom surface of the tank base 11, and the sediment generated in the tank body 1 is located above the circular dense mesh disk 24. At the same time, during sewage treatment, the power piece drives the conical block 27 and the circular dense mesh disk 24 to rotate and stir the sewage. After the sewage is treated, the water is discharged through the outlet pipe 3 and the first motor 2 is started at the same time. The first motor 2 drives the screw 21 to rotate, and the rotation of the screw 21 drives the round block 22 to move up, and the round block 2 2 moves upward, driving the annular block 23 and the circular dense mesh disk 24 to move upward. During the upward movement of the circular dense mesh disk 24, solid impurities such as sediments in the sewage are filtered. When the circular dense mesh disk 24 is at the top, it is just at the position of the annular groove 13. At this time, the power part drives the conical block 27 and the circular dense mesh disk 24 to rotate again, and uses centrifugal force to throw the filtered impurities and ozone solid catalyst through the annular groove 13 into the annular collecting cylinder 15. The solid impurities and ozone solid catalyst are collected by the annular collecting cylinder 15. The above operation is repeated to complete the impurity treatment of the ozone catalytic reactor without stopping, avoiding secondary filtration and ensuring the water quality. The quality of the sewage is improved, and the sewage treatment efficiency is improved; the stirring plate 51 is limited by the rotating axis, and is shorter at the top and longer at the bottom. When the sewage is treated, the circular dense mesh disk 24 is attached to the bottom surface of the tank base 11, and the stirring plate 51 is in an unfixed state. When the rotating column 28 rotates around the second rotating axis 291 and the screw 21, it will rotate through the opening part. The rotation of the rotating column 28 drives a group of stirring plates 51 to open, so that the sewage is locally turbulent. At the same time, the rotating column 28 is filled with ozone to increase the stirring force and ensure the reaction efficiency. Because the ozone solid catalyst is generally solid, and the catalyst theoretically will not be lost in the sewage, the ozone solid catalyst is generally deposited at the bottom of the tank body 1. The catalysis of the upper sewage is not uniform enough. A group of spherical catalysts 62 is provided in the arc-shaped cavity 6 of the stirring plate 51. The water flows in through the first through groove 61. When the ozone gas is released by the rotating column 28, the spherical catalyst 62 is used to catalyze the reaction. Theoretically, there will be no loss of the spherical catalyst 62, but in actual operation, there are impurities or wear on the spherical catalyst 62. Therefore, the tank cover barrel 12 is removed from the tank base 11, the output end of the first motor 2 is removed from the screw 21, the tank cover barrel 12 and the tank base 11 are separated, and the spherical catalyst 62 is taken out and replaced through the circular through groove 63, and the circular dense mesh disk 24 is cleaned at the same time.
