Description

Technical Field

[0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a catalytic oxidation device for removing organic pollutants from industrial wastewater. Background Art

[0002] The treatment process of organic wastewater is relatively complicated and requires the cooperation of multiple treatment processes, including grid filtration and coagulation sedimentation in the pretreatment stage, oxidation treatment in the catalytic oxidation stage, and sludge dehydration in the post-treatment stage. It is necessary to select the corresponding process for treatment according to different types of wastewater;

[0003] After searching, the prior art publication number CN118084177A is an ozone catalytic oxidation device for wastewater treatment. For the treatment of organic wastewater, this scheme is set up as follows: "The winding shaft starts to rotate through the drive of the second motor, thereby driving the winding sleeve to rotate, and winding and winding the two ropes. As the ropes are gradually wound, the connecting sleeve is subjected to tension, thereby pulling the two steel sheets to bend. The bending of the steel sheets makes them fit tightly on the outer wall of the mounting ring to form an arc-shaped structure. The steel sheets make the multiple docking blocks also bend in an arc shape. The aeration pipes originally arranged in a straight line gradually unfold with the bending of the docking blocks to form an arc-shaped arrangement that adapts to different widths, so that the device can adapt to water tanks of different sizes, ensuring that the aeration pipes can effectively cover the entire water tank area, and improving the efficiency and quality of wastewater treatment." The above scheme can adapt to water tanks of different sizes in the oxidation catalysis stage, so that the aeration effect can achieve the best effect;

[0004] However, the following situations may occur during use, that is, the wastewater level in the reservoir is higher than the aeration pipe, and the wastewater level is lower than the aeration pipe. When the above situation occurs, the utilization rate of ozone sprayed from the aeration nozzle is also different. When the wastewater level is lower than the aeration pipe, the ozone sprayed from the aeration nozzle above the liquid level will be lost and wasted; therefore, the utilization efficiency of ozone will be greatly reduced, and the treatment cost will be increased;

[0005] Therefore, the present invention provides a catalytic oxidation device for wastewater organic matter that can solve the above problems. Summary of the invention

An air inlet pipe 261 connected to the air supply pipe 24 is provided on the top of the aeration pipe 26. Aeration holes 264 are provided on the aeration pipe 26. The support arm drives the aeration pipe to move along the guide rail to aerate and oxidize the wastewater in the oxidation pond.

[0059] Furthermore, an ear plate 262 is provided inside the aeration tube 26, and the two halves of the aeration tube are combined into a complete aeration tube 26 by bolts and the ear plate 262, which can be disassembled to facilitate the installation of the internal structure.

[0060] An adjusting shaft 263 is disposed inside the aeration tube 26 , and both ends of the adjusting shaft 263 are rotatably connected to the aeration tube 26 .

[0061] A sealing plate 265 is further provided inside the aeration tube 26 , and the sealing plate 265 is used to block the aeration hole 264 . The sealing plates 265 are connected and fixed to each other through a connecting arm 2654 .

[0062] The sealing plates 265 are provided in several groups, and the sealing plates 265 are arranged in sequence from top to bottom along the aeration pipe 26 . The sealing plates 265 are rotatably connected to the adjustment shaft 263 through the connecting arm 2654 .

[0066] Application effect of the aeration tube 26: the rotation of the adjusting shaft 263 drives the rotation of the bottom sealing plate 265 of the adjusting shaft 263; the forward and reverse rotation of the adjusting shaft 263 can achieve two different effects; when all the sealing plates 265 are completely closed by rotating the adjusting shaft 263 in cooperation with the first stopper 2652 and the second stopper 2653 so that the aeration holes 264 are completely closed, the first stopper 2652 on the sealing plate 265 and the second stopper 2653 of the sealing plates 265 adjacent to each other are in a state of mutual conflict; therefore, the rotation in one direction is when all the sealing plates 265 close the aeration holes 264, and the adjusting shaft 263 is continuously rotated through the first stopper 2652 on the bottom sealing plate 265 to push the adjacent second stopper 2653 so that all the sealing plates 265 rotate simultaneously, thereby being able to open all the aeration holes 264 at the same time. 64 for aeration; further, when the adjusting shaft 263 rotates in the reverse direction, the sealing plate 265 at the bottom of the adjusting shaft 263 rotates one circle, so that the first stopper 2652 reversely overlaps and contacts the second stopper 2653 of the upper sealing plate 265. In this state, the sealing plate 265 at the bottom continues to rotate to open the bottom aeration hole 264, and at the same time drives the upper sealing plate 265 to rotate to open the upper aeration hole 264 for aeration. According to the above process, the aeration holes 264 on the aeration pipe 26 can be selectively opened according to the wastewater liquid level. When the liquid level is higher than the top of the aeration pipe 26, the aeration holes 264 can be quickly opened as a whole for aeration. When the liquid level is lower than the top of the aeration pipe 26, the adjusting shaft 263 can be rotated in the reverse direction to open the aeration holes 264 in sequence from bottom to top, so that it can be accurately aerated and ozone leakage and waste can be avoided.

[0068] Furthermore, a fixing plate 28 is provided at one end of the aeration tube 26 and is connected to all the aeration tubes 26 in sequence, thereby providing an auxiliary stabilizing effect on the aeration tube 26 .

[0069] Furthermore, a rotating shaft 27 is provided between the support arm 23 and the fixed plate 28. The rotating shaft 27 is provided on one side of the aeration pipe 26.
