[0002] With rapid economic development, my country's water resources and environment have been severely polluted and damaged, posing a significant threat to our health and survival. Researching measures to improve water environmental issues is crucial for protecting the human environment and implementing sustainable development. While there are a variety of domestic wastewater purification technologies, the most basic principle is to rely on the action of microorganisms to remove pollutants from water, primarily including traditional biofilm and activated sludge processes.

[0003] In the process of sewage treatment, the biofilm method has strong resistance to shock load, but the retention time is long and the cost is high; the retention time of the activated sludge method is lower than that of the biofilm method, but when the COD cr When the concentration is low, a certain amount of carbon source needs to be added to maintain the sludge concentration within the system.

[0041] Exemplary upper kit

[0042] like Figure 6-Figure 7As shown, further, some embodiments of the present invention provide a specific structure of the above-mentioned upper kit 46, where the upper kit 46 of this structure includes an upper fixed tube 461, an upper block seat 462, and an upper sleeve body 463, wherein the upper fixed tube 461 is installed at the bottom of the seat plate 431, and the upper block seat 462 is installed at the bottom of the upper fixed tube 461, the upper sleeve body 463 is installed at the bottom of the upper block seat 462, and the upper sleeve body 463 is installed on the lower kit 47, and two inner clamps are installed in the upper sleeve body 463, where the two inner clamps are used to fix the above-mentioned lower kit 47, so that the assembly between the upper kit 46 and the lower kit 47 can be realized, thereby improving installation efficiency.

[0043] Furthermore, two opposite first inner grooves 464 are provided on the inner wall of the upper sleeve body 463, and two vertical sliding grooves 465 are provided on its outer wall, so that the first inner groove 464 and the vertical sliding groove 465 are connected to each other, and the above-mentioned inner clamping parts include an inner rotating rod 466, a sliding ring 467, and an inner driving rod 468, wherein the inner rotating rod 466 is rotatably installed in the first inner groove 464 through an inner shaft 4661, and the above-mentioned sliding ring 467 can be slidably installed on the outer wall of the upper sleeve body 463 up and down, and the vertical sliding groove 465 also has an inner driving rod 468 connected to the sliding ring 467, so when the sliding ring 467 is moved upward, it drives the internal inner driving rod 468 to move upward along the vertical sliding groove 465, and then pushes against and drives the inner rotating rod 466 to rotate into the inner clamping groove 470 of the lower kit 47, thereby realizing the assembly between the upper kit 46 and the lower kit 47, and improving installation efficiency.

[0044] Exemplary lower kit

[0045] like Figure 7-Figure 8 As shown, further, some embodiments of the present invention provide a specific structure of the above-mentioned lower kit 47, where the lower kit 47 of the structure includes a lower solid cylinder 471, a lower stopper 472, and a lower sleeve body 473, wherein the lower solid cylinder 471 is installed on the metering detection tube 41, and the lower stopper 472 is installed on the upper end of the lower solid cylinder 471, and the lower sleeve body 473 is installed on the upper end of the lower stopper 472. In order to be fixed with the above-mentioned upper sleeve body 463, the lower sleeve body 473 is fixed here. Two opposing second inner grooves 474 are formed on the outer wall of the housing 73. An inner compression spring 475 and an outer push block 476 are installed in the second inner grooves 474. The inner compression spring 475 is located on the inner side of the outer push block 476 and abuts against the outer push block 476. As a result, the outer push block 476 also abuts against the inner rotating rod 466 and cooperates with the inner drive rod 468. In this way, the upper and lower ends of the inner rotating rod 466 cooperate to fix the inner rotating rod 466 inside the lower sleeve body 473.

[0046] When it is necessary to open the lower sleeve body 473, the sliding ring 467 can be moved downward, and the sliding ring 467 drives the inner drive rod 468 to move downward along the vertical slide groove 465, and then the inner drive rod 468 pushes the lower end of the inner rotating rod 466 inward, and then the inner rotating rod 466 pushes the outward pushing block 476 toward the second inner receiving groove 474, and then the upper end of the inner rotating rod 466 is rotated from the inner clamping groove 470 to the first inner receiving groove 464, and then the upper kit 46 can be pulled out from the lower kit 47 to achieve efficient disassembly.

[0047] like Figures 9-12 As shown, further, there is an inner receiving chamber 477 in the lower block seat 472, and the inner receiving chamber 477 is connected to the inner passage 4701, and the inner passage 4701 can pass through the above-mentioned sensor body 45. An inner shielding component 48 is installed in the inner receiving chamber 477, and the inner shielding component 48 is used to seal the interior of the lower kit 47. In this way, when the sensor body 45 is taken out for inspection, the sewage in the metering and detection tube 41 can be prevented from overflowing, which is more convenient to use.

[0048] Here, two corresponding driving grooves 478 are opened on the upper end surface of the lower block seat 472, and correspondingly, a driving vertical rod 469 corresponding to the driving groove 478 is provided at the lower end of the upper sleeve body 463. Therefore, when the driving vertical rod 469 enters the driving groove 478, the inner shielding assembly 48 can be driven, so that the inner shielding assembly 48 is in an open state, which facilitates the sensor body 45 to pass through the upper kit 46 and the lower kit 47 and enter the metering and detection tube 41, so that the metering and detection module 42 can detect sewage through the sensor body 45.

[0049] Exemplary inner shielding assembly

[0051] Therefore, when the driving vertical rod 469 enters the inner receiving chamber 477, it will hit the oblique push groove 487, thereby generating a component force to rotate the inner track ring 483 and make the inner torsion ring 482 retract and rotate, so that the inner rotating seat 481 is also active, and the bottom of the inner rotating seat 481 has an inner track groove 484, and the inner track groove 484 has an inner track shaft 485, and the inner blocking seat 486 is installed on the inner track shaft 485, so that the inner blocking seat 486 moves along the inner track groove 484 through the inner track shaft 485, and the two inner The shielding seats 486 are separated from each other, and then the inner passage 4701 is in an unobstructed state, and the sensor body 45 can pass through the above-mentioned metering detection tube 41; when the metering detection module 42 and the sensor body 45 are removed for maintenance, the driving vertical rod 469 is separated from the inclined push groove 487, and the inner rotating seat 481 is driven to rotate under the action of the inner twisting ring 482, so that the two inner shielding seats 486 are moved closer to each other to block the inner passage 4701, thereby preventing the sewage in the metering detection tube 41 from overflowing, making it more convenient to use. Furthermore, the two inner shielding seats 486 can be magnetically connected to each other to increase the sealing performance.
