Description

Technical Field

[0001] This invention relates to the technical field of wastewater treatment, specifically a multi-stage bubbling oxidation tower type wastewater treatment reactor. Background Technology

[0002] The bubbling oxidation tower-type wastewater treatment reactor introduces air and ozone into the tower through an aeration device located at the bottom. When wastewater enters from the bottom of the reactor, it is simultaneously subjected to the synergistic effects of ultraviolet (UV) radiation, hydrogen peroxide, and ozone. These oxidants can oxidize and decompose most of the organic matter in the wastewater, thereby achieving the purpose of purifying the water quality.

[0003] For example, patent application CN103420528A discloses a multi-stage bubbling oxidation tower type wastewater treatment reactor, which includes a UV lamp, a dosing pump, a baffle plate, and a reaction zone located between two baffle plates. The UV lamp is installed in the cylindrical area of ​​the baffle plate, and a UV lamp is installed every other baffle plate. The feed port is located between two baffle plates. The wastewater treatment reactor has a wastewater inlet pipe at the bottom and a wastewater outlet pipe at the top.

[0004] However, the above technical solutions still have some problems. Although the above sewage treatment reactor can deliver a predetermined amount of gas (air or ozone) into the bubbling oxidation tower, the amount of gas delivered is difficult to adjust. That is, regardless of the amount of organic matter in the sewage, the amount of gas introduced is fixed, which may lead to excessive or insufficient gas introduction, resulting in ozone loss and failure of sewage treatment.

Gas is introduced into a gas inlet, and then the gas enters the gas distributor through the air inlet pipe, so that the gas is evenly dispersed into the sewage in the form of bubbles. Then, based on the results of prior sampling and testing of the sewage or subsequent sampling and testing of a portion of the treated sewage, gas is injected into the gas inlet.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0060] The bubbling oxidation tower 1, through a gas distributor and a liquid distributor installed inside the bubbling oxidation tower 1, evenly disperses gas into the wastewater in the form of bubbles. The air inlet device 5, connected to the air inlet end of the gas distributor inside the bubbling oxidation tower 1 via an air inlet pipe 7, is used to supply gas to the gas distributor. The air inlet device 5 includes a mounting base 51, and respectively mounted on the mounting base 51 are an adjustment component 52, a first gas delivery component 53, a second gas delivery component 54, a venting component 55, and an air inlet nozzle 56. The air inlet nozzle 56 is connected to the air inlet pipe 7 for gas transport. The adjustment component 52 and the venting component 55 are used to adjust the gas delivery rate and the rate at which microorganisms decompose organic matter. The first gas delivery component 53... The second gas delivery component 54 delivers different types of gas as needed, allowing the gas to be delivered to the gas distributor through the air inlet 56 and air inlet pipe 7. The gas reacts with the organic matter in the wastewater, enabling the treated wastewater to meet the predetermined discharge standards. Gas is injected into the first connecting cavity 528 through the air injection nozzle 521, pushing the drive block 526 to move in the first connecting cavity 528. The moving drive block 526 drives the drive rod 527 to move, thereby adjusting the gap between one end of the drive rod 527 and the wall of the separator pipe 533. Based on the pre-sampling and testing results of the wastewater, the size of the gap is adjusted, thereby adjusting the amount of gas entering the bubbling oxidation tower 1 to complete the removal of organic matter from the wastewater.

[0061] The adjustment assembly 52 includes a placement cavity formed on the mounting base 51, a drive rod 527 located within the placement cavity, a first connecting seat 523 and an air injection nozzle 521 disposed on the mounting base 51, a first cap 522 screwed to the first connecting seat 523, a second connecting seat 524 connected to the first cap 522, a drive block 526 sleeved on the drive rod 527, a sealing block 5212 connected to the drive block 526 and abutting against the inner wall of the placement cavity, and a second limiting spring 5211 for connecting the drive block 526 and the second connecting seat 524; wherein a first communicating cavity 528 is formed between the inner wall of the first connecting seat 523 and the first cap 522, the air injection nozzle 521 communicates with the first communicating cavity 528, and the drive block 526 and the sealing block 5212 are located in the first communicating cavity 528. 28; the second connecting seat 524 has a U-shaped structure with a through hole for the drive rod 527 to pass through; the outer wall of the drive block 526 abuts against the inner wall of the first connecting seat 523; by adjusting the position of the first cap 522 in the axial direction of the drive rod 527, the distance between the drive block 526 and the connection point of the first communicating cavity 528 and the air injection nozzle 521 is changed, the gap between the drive rod 527 and the air inlet on the air inlet 56 is adjusted, and the gas delivery volume is adjusted; the adjusting assembly 52 also includes a connecting block 529 sleeved on the drive rod 527, a second cap 525 screwed to the second connecting seat 524, and two first limiting springs 5210 of different diameters for connecting the connecting block 529 and the second cap 525 and respectively sleeved on the drive rod 527; the connecting block 529 is connected to the drive block 526;

[0062] By rotating the first cap 522, the first cap 522 moves on the first connecting seat 523, changing the position of the drive block 526 within the first communicating cavity 528, thus completing the installation of the first cap 522. Then, by rotating the second cap 525, the distance between one end of the drive rod 527 and the tapered end of the separator tube 533 can be adjusted via the two second limiting springs 5211, thereby adjusting the gap between the outer wall of the drive rod 527 and the inner wall of the separator tube 533. A preset gas output volume is established before gas transport operations, and then, during wastewater treatment, gas can be input into the first gas inlet 531. Then the gas can enter the gas distributor through the air inlet pipe 7, so that the gas is evenly dispersed into the sewage in the form of bubbles. Then, according to the sampling and testing results of the sewage beforehand or the sampling and testing results of the sewage discharged after treatment, the gas is injected into the air inlet 521. By injecting gas into the first connecting cavity 528, the air pressure in the first connecting cavity 528 is increased, which pushes the drive block 526 closer to the second cap 525. The moving drive block 526 can drive the drive rod 527 to move, change the gap between the outer wall of the drive rod 527 and the inner wall of the separator 533, increase the gas input, and improve the decomposition efficiency of organic matter in the sewage.

[0063] The sealing block 5212 can isolate the first connecting cavity 528 from the placement cavity, thereby ensuring the smooth progress of the adjustment work. By changing the amount of gas injected, the position of the drive block 526 in the first connecting cavity 528 can be changed, thereby adjusting the gap between one end of the drive rod 527 and the partition tube 533, and completing the adjustment of the amount of gas injected.

[0064] The first air supply assembly 53 includes a first air supply nozzle 531 disposed on the mounting base 51, and a partition tube 533 sleeved on the drive rod 527 and connected to the inner wall of the placement cavity; a predetermined gap exists between the partition tube 533 and the outer wall of the drive rod 527, the gap being a second communicating cavity 532, and the first air supply nozzle 531 communicating with the second communicating cavity 532; both the partition tube 533 and the drive rod 527 have a tapered structure near the air inlet 56, and the position of the drive rod 527 can be adjusted. Adjust the distance between the outer wall of the drive rod 527 and the inner wall of the partition tube 533 to adjust the gas flow rate. When it is necessary to charge gas into the bubbling oxidation tower 1, the gas is delivered from the first gas inlet 531 to the second connecting cavity 532 on the mounting base 51. Then the gas flows out of the inlet 56 between the outer wall of the drive rod 527 and the inner wall of the partition tube 533 along the second connecting cavity 532, enters the inlet pipe 7 through the inlet 56, and is discharged from the gas distributor in the bubbling oxidation tower 1, thus completing the gas delivery work.

[0065] The second air supply assembly 54 includes a second air supply nozzle 541 disposed on the mounting base 51, a connecting plate 544 sleeved on the partition tube 533 and connected to the mounting base 51, and a plurality of connecting holes disposed on the connecting plate 544; a predetermined gap exists between the outer wall of the partition tube 533 and the inner wall of the air inlet on the air inlet nozzle 56, and a predetermined space exists between the outer wall of the partition tube 533 and the mounting base 51, which is a fourth connecting cavity 543; the second air supply assembly 54 also includes a connection for connecting the air outlet end of the second air supply nozzle 541 to the fourth connecting cavity 543. The third connecting cavity 542 of cavity 543, and the fifth connecting cavity 545 for connecting the connecting hole and the gap; in order to increase the gas input or when it is necessary to input other gases into the bubbling oxidation tower 1, gas can be injected into the second gas inlet 541, and then the gas can be discharged from the area between the inner wall of the gas inlet of the gas inlet 56 and the outer wall of the partition tube 533 along the connecting hole on 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.

[0066] The venting assembly 55 includes a vent nozzle 551 connected to the mounting base 51, a third connecting base 552 connected to the vent nozzle 551, a pressure relief motor 553 mounted on the third connecting base 552, a fixed cavity 556 opened on the third connecting base 552, a first vent pipe 554 connected to the output end of the pressure relief motor 553 and located within the fixed cavity 556, and a second vent pipe 555 connected to the first vent pipe 554; the outer wall of the first vent pipe 554 abuts against the inner wall of the fixed cavity 556, and its circumferential direction is provided with a vent hole communicating with the venting channel inside the first vent pipe 554; when it is necessary to readjust the position of the drive rod 527, air is injected into the first communicating cavity 528 or the valve between the vent nozzle 551 and the third connecting base 552 is opened to vent, depending on the actual situation. During the gas 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 this area, the pressure relief motor 553 starts to work. The moving pressure relief motor 553 can drive the first vent pipe 554 to rotate, so that the vent hole on the first vent pipe 554 can overlap with the connecting pipe. At this time, the gas can be discharged along the first vent pipe 554 and the second vent pipe 555, thereby reducing the pressure in the first connecting cavity 528. This causes the drive block 526 to move towards the air inlet 56 and adjusts the position of the drive rod 527. Through the segmented gas release method, the gas pressure in the first connecting cavity 528 is prevented from dropping too quickly, so that the drive rod 527 and the separator pipe 533 can quickly reach the predetermined gas pressure without having to increase the gas pressure from zero, thus increasing the reaction rate of the device.

[0067] In a further embodiment, through the mutual cooperation between the first cap 522, the second cap 525, the first limiting spring 5210, and the second limiting spring 5211, the position of the drive block 526 in the first connecting cavity 528 can be adjusted during installation. Then, by injecting a certain amount of gas into the gas injection nozzle 521, the drive block 526 can move a certain distance towards the second cap 525, thereby adjusting the gap between the drive rod 527 and the inner wall of the partition tube 533, and adjusting the amount of gas injected. When it is necessary to adjust the gap between the drive rod 527 and the inner wall of the partition tube 533 again, the gas pressure in the first connecting cavity 528 needs to be reduced by the venting component 55, so that the drive block 526 moves towards the air inlet 56. Through the cooperation of the valve, connecting pipe, and pressure relief motor 553, the pressure can be released in stages each time the venting component 55 works. Through the cooperation of pressure relief and adjustment component 52, the drive rod 527 can be positioned in a predetermined position, ensuring the smooth operation of gas injection.

The rotating rotary motor 612 can drive the drive gear 613 to rotate, and the driving gear 613 can drive the first gear ring 614 to rotate, thereby adjusting the position of the mounting frame 615, and thus adjusting the collection area of ​​the collection component 63. The set adjustment component 52 can not only complete the collection of treated sewage, but also transport the collected sewage to a predetermined location.

The moving transmission screw 637 can drive the drive seat 638 to move, and the moving drive seat 638 can drive the sampling rod in the sampler 639 to move, changing the position of the piston block in the sampling cylinder, thereby completing the sampling of sewage. After the sampling 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. Then the operator can test it and adjust the gas injection volume according to the test results. Sewage that meets the standards is discharged, and otherwise the sewage is decontaminated again. The adjustable motor 631 can fine-tune the collection area of ​​the collection component 63, so that it can collect sewage from multiple areas.

[0071] In a further embodiment, for safety reasons, valves may be installed on the air injection nozzle 521, the air vent 551, the first air supply nozzle 531, and the second air supply nozzle 541.

[0072] Working principle description: Before sewage treatment, the first cap 522 is rotated, causing it to move on the first connecting seat 523. This changes the position of the drive block 526 within the first communicating cavity 528, completing the installation of the first cap 522. Then, the second cap 525 is rotated. Two second limiting springs 5211 adjust the distance between one end of the drive rod 527 and the tapered end of the separator tube 533, thereby adjusting the gap between the outer wall of the drive rod 527 and the inner wall of the separator tube 533. A preset gas output is established before gas transport. During sewage treatment, the gas can be supplied to the first gas inlet. Gas is input into 531, and then the gas can enter the gas distributor through the air inlet pipe 7, so that the gas is evenly dispersed into the sewage in the form of bubbles. Then, according to the sampling and testing results of the sewage beforehand or the sampling and testing results of the sewage discharged after treatment, gas injection is performed into the air injection nozzle 521. By injecting gas into the first connecting cavity 528, the air pressure in the first connecting cavity 528 is increased, which pushes the drive block 526 closer to the second cap 525. The moving drive block 526 can drive the drive rod 527 to move, change the gap between the outer wall of the drive rod 527 and the inner wall of the separator pipe 533, increase the amount of gas input, and improve the decomposition efficiency of organic matter in sewage.

[0073] When it is necessary to charge gas into the bubbling oxidation tower 1, the gas is delivered from the first gas inlet 531 to the second connecting cavity 532 on the mounting base 51. Then the gas flows out of the inlet 56 between the outer wall of the drive rod 527 and the inner wall of the partition tube 533 along the second connecting cavity 532, enters the inlet pipe 7 through the inlet 56, and is discharged from the gas distributor in the bubbling oxidation tower 1, thus completing the gas delivery work.

[0074] In order to increase the gas input or when other gases need to be introduced into the bubbling oxidation tower 1, gas can be injected into the second gas inlet 541. Then the gas can be discharged from the area between the inner wall of the gas inlet 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. The gas can be transported into the bubbling oxidation tower 1 to complete the gas transportation work.

[0075] When the position of the drive rod 527 needs to be readjusted, air is introduced into the first connecting cavity 528 or the valve between the vent nozzle 551 and the third connecting seat 552 is opened to release air, depending on 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 this area, the pressure relief motor 553 starts to work. The moving pressure relief motor 553 can drive the first vent pipe 554 to rotate, so that the vent hole on the first vent pipe 554 can overlap with the connecting pipe. In this region, the gas can be discharged through the first vent pipe 554 and the second vent pipe 555, thereby reducing the pressure in the first connecting cavity 528, causing the drive block 526 to move towards the air inlet 56, adjusting the position of the drive rod 527. Through the segmented venting method, the gas pressure in the first connecting cavity 528 is prevented from dropping too quickly, and the drive rod 527 is prevented from colliding with the separator pipe 533. At the same time, the gas pressure in the first connecting cavity 528 can quickly reach the predetermined gas pressure without having to increase the gas pressure from zero, thus improving the reaction rate of the device.

[0076] When the position of the collection component 63 needs to be adjusted, the rotary motor 612 starts working. The rotating rotary motor 612 drives the drive gear 613 to rotate, which in turn drives the first gear ring 614 to rotate, thereby adjusting the position of the mounting frame 615 and thus adjusting the collection area of ​​the collection component 63. The collection component 63 can not only collect treated wastewater but also transport the collected wastewater to a designated location. Then, the operator tests the collected sample to determine whether the wastewater meets the discharge standards, or, based on the test results, increases the injection of oxidant gas or other gases to remove organic matter from the wastewater. When a secondary adjustment of the collection area of ​​the collection component 63 is needed, the displacement motor 623 starts working. The rotating displacement motor 623 drives the main gear 624 to rotate, which in turn drives the driven gear 625 to rotate. The driven gear 625 causes the rotating shaft 626 to rotate, thereby driving the rotating shaft 626 to rotate. The driven gear 627 moves, driving the second gear ring 628 to rotate, causing the adjusting frame 622 and the support frame 621 to rotate. At this time, the limiting shaft 6210 can move in the limiting groove on the limiting seat 629, thereby changing the collection position of the collection component 63. When the collection component 63 is in the predetermined collection area, the collection motor 636 starts to work. The moving collection motor 636 drives the transmission screw 637 to rotate, and then the moving transmission screw 637 drives the drive seat 638 to move. Then the moving drive seat 638 drives the sampling rod in the sampler 639 to move, changing the position of the piston block in the sampling cylinder, thereby completing the sampling of sewage. After the sampling 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 in the predetermined injection area, and then the sewage in the sampling cylinder can be injected into the predetermined position. Then the operator can test it and adjust the gas injection volume according to the test results.
