When sewage enters from the bottom of the reactor, it will be subjected to the synergistic effect of ultraviolet rays (UV), hydrogen peroxide and ozone at the same time. These oxidants can oxidize and decompose most of the organic matter in the sewage, thereby achieving the purpose of purifying the water quality.

[0003] For example, the patent application with publication number CN103420528A discloses a multi-stage bubbling oxidation tower sewage treatment reactor, including a UV lamp, a dosing pump, a baffle and a reaction zone located between two layers of baffles.

At the same time, the sewage that meets the standards will be discharged, otherwise the sewage will be decontaminated again; and the adjustment motor 631 can be set to fine-tune the collection area of ​​the collection component 63, so that it can collect sewage in multiple areas.

[0032] In a further embodiment, in order to ensure safety, valves may be installed on the gas injection nozzle 521 , the air release nozzle 551 , the first gas delivery nozzle 531 and the second gas delivery nozzle 541 .

[0033] Working principle description: Before sewage treatment, the first rotary cover 522 is rotated to move the first rotary cover 522 on the first connecting seat 523, and the position of the driving block 526 in the first connecting cavity 528 is changed to complete the installation of the first rotary cover 522, and then the second rotary cover 525 is rotated. Then, the distance between one end of the driving rod 527 and the conical structure end on the separation tube 533 can be adjusted by setting two second limit springs 5211, so as to adjust the gap between the outer wall of the driving rod 527 and the inner wall of the separation tube 533. Before gas transportation, a gas output volume is preset, and then when sewage treatment is carried out, the gas output volume can be adjusted by feeding the first gas delivery nozzle 531, and then the gas can enter the gas distributor along the air inlet pipe 7, so that the gas is evenly dispersed in the sewage in the form of bubbles, and then according to the sampling test results of the sewage in advance or the subsequent sampling test results of part of the sewage discharged after treatment, the gas injection nozzle 521 is injected with gas, and the air pressure in the first connecting cavity 528 is increased by injecting gas into the first connecting cavity 528, so as to push the driving block 526 close to the second rotary cover 525, and the moving driving block 526 can drive the driving rod 527 to move, thereby changing the gap between the outer wall of the driving rod 527 and the inner wall of the partition tube 533, increasing the input amount of gas, and improving the decomposition efficiency of organic matter in the sewage; When it is necessary to charge the bubbling oxidation tower 1 with gas, the gas is delivered from the first gas delivery nozzle 531 to the second connecting cavity 532 on the mounting seat 51, and then the gas flows out of the gas inlet nozzle 56 along the second connecting cavity 532 from between the outer wall of the driving rod 527 and the inner wall of the partition tube 533, enters the gas inlet pipe 7 through the gas inlet nozzle 56, and is discharged from the gas distributor in the bubbling oxidation tower 1, completing the gas delivery work; In order to increase the input amount of gas or when other gases need to be input into the bubbling oxidation tower 1, gas can be injected into the second gas delivery nozzle 541, and then the gas can be discharged from the area between the inner wall of the gas inlet of the gas inlet nozzle 56 and the outer wall of the partition tube 533 along the third connecting cavity 542, the fourth connecting cavity 543, the connecting hole on the connecting plate 544 and the fifth connecting cavity 545, and the gas can be transported to the bubbling oxidation tower 1 to complete the gas transportation work; When the position of the driving rod 527 needs to be readjusted, the first connecting chamber 528 is inflated or the valve between the air release nozzle 551 and the third connecting seat 552 is opened to release air according to the actual situation. During the air release operation, since there is a connecting pipe between the third connecting seat 552 and the valve, when the gas fills the connecting pipe in the area, the pressure relief motor 553 starts to work, and the moving pressure relief motor 553 can drive the first air release pipe 554 to rotate, so that the air release hole on the first air release pipe 554 can overlap with the connecting pipe. domain, at this time, the gas can be discharged along the first air release pipe 554 and the second air release pipe 555, thereby reducing the pressure in the first connecting chamber 528, so that the driving block 526 moves toward the direction of the air inlet nozzle 56, and the position of the driving rod 527 is adjusted. Through the segmented air release method, the air pressure in the first connecting chamber 528 is prevented from decreasing too quickly, and the collision between the driving rod 527 and the partition tube 533 is prevented. At the same time, the air pressure in the first connecting chamber 528 can quickly reach the set air pressure, and there is no need to increase the air pressure from zero, thereby improving the reaction rate of the device; When the position of the collection component 63 needs to be adjusted, the rotating motor 612 starts working, the moving rotating motor 612 can drive the driving gear 613 to rotate, and the moving driving gear 613 can drive the first gear ring 614 to rotate, so as to adjust the position of the mounting frame 615, and then adjust the collection area of ​​the collection component 63. The collection component 63 can not only complete the collection of the treated sewage, but also transport the collected sewage to a predetermined position. Then the operator tests the collected samples to determine whether the sewage meets the discharge standard, or increase the injection amount of the oxidant gas or other gas according to the test results, so as to complete the removal of organic matter in the sewage. When the collection area of ​​the collection component 63 needs to be adjusted for the second time, the displacement motor 623 starts working, the moving displacement motor 623 can drive the main gear 624 to rotate, the moving main gear 624 can drive the slave gear 625 to rotate, and the moving slave gear 625 rotates the rotating shaft 626, thereby driving the The driven gear 627 moves, and the moving driven gear 627 can drive the second gear ring 628 to move, so that the adjustment frame 622 and the support frame 621 rotate. At this time, the limit shaft 6210 can move in the limit groove on the limit seat 629, thereby changing the collection position of the collection component 63; when the collection component 63 is located in the predetermined collection area, the collection motor 636 starts to work, and the moving collection motor 636 can drive the transmission screw 637 to rotate, and then the moving transmission screw 637 can drive the drive seat 638 to move, and then the moving drive seat 638 can drive the sampling rod in the sampler 639 to move, change the position of the piston block in the sampling cylinder, and complete the sampling and collection of sewage. After the sampling work is completed, the position of the collection component 63 is changed again with the cooperation of the displacement component 62 and the rotation component 61, so that it is located in the predetermined injection area, and then the sewage in the sampling cylinder can be injected into the predetermined position, and then the operator can detect it and adjust the gas filling amount according to the detection result.
