Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a municipal wastewater treatment device. Background Technology
[0002] Municipal wastewater treatment refers to the process of treating wastewater generated by urban residents in their daily lives, commercial activities, and industrial production. This wastewater includes domestic sewage, industrial wastewater, and stormwater runoff. Municipal wastewater treatment typically requires aeration, the main purpose of which is to introduce oxygen into the wastewater, promoting the reproduction and activity of aerobic microorganisms and accelerating the decomposition of organic matter.
[0003] Currently, municipal wastewater treatment typically involves using blowers to pump air into aeration pipes, which then discharge the air into the aeration treatment tank through aeration ports. This creates a large number of bubbles for aeration. However, the size of the aeration ports is currently fixed and difficult to adjust. The size of the aeration ports directly affects the aeration effect and the wastewater treatment effect. If the ports are too large, although the aeration volume is high, the oxygen will not mix evenly in the water, easily creating stagnant areas and hindering the degradation of organic matter in the water. Conversely, if the ports are too small, the aeration intensity will decrease, which will also affect the treatment effect. This needs to be improved. Utility Model Content

A fixing plate 476 is provided above the aeration tank 1. The top of a straight rod 478 is fixedly connected to the bottom of the fixing plate 476. A support plate is provided above the fixing plate 476. 3. Support frames 2 are fixedly installed at the four corners of the bottom of the support plate 3. The bottom of the support frames 2 is fixedly installed on the top of the aeration treatment tank 1. A blower 41 is fixedly installed on the left side of the top of the support plate 3. An air supply pipe 42 is fixedly installed at the output end of the blower 41. An air distribution pipe 43 is fixedly installed on the lower left side inside the aeration treatment tank 1. The left ends of multiple connecting pipes 44 are fixedly installed on the right side of the air distribution pipe 43. The connecting pipes 44 communicate with the interior of the air distribution pipe 43. The bottom end of the air supply pipe 42 extends into the interior of the aeration treatment tank 1 and is fixedly installed on the air distribution pipe 43. On the left side, the bottom end of the air supply pipe 42 communicates with the interior of the air distribution pipe 43. A piston head 479 is movably sleeved above the interior of the aeration pipe 45. A straight rod 478 is movably sleeved at the top of the aeration pipe 45. The bottom end of the straight rod 478 is fixedly connected to the top of the piston head 479. A mounting cover 47 is fixedly installed in the middle of the top of the support plate 3. A motor 471 and a worm gear reducer 472 are fixedly installed on the top of the inner wall of the mounting cover 47. The output end of the motor 471 is fixedly connected to the input end of the worm gear reducer 472. A lead screw 473 is fixedly installed at the output end. The bottom end of the lead screw 473 is rotatably installed at the middle of the top of the support plate 3 via a bearing. A connecting plate 474 is provided inside the mounting cover 47. The middle part of the connecting plate 474 is threaded to the outer wall of the lead screw 473. Connecting rods 475 are fixedly connected to the four corners of the bottom of the connecting plate 474. The bottom end of the connecting rod 475 passes through the support plate 3 and is fixedly connected to the top of the fixed plate 476.

[0023] In this embodiment, the combination of blower 41, air supply pipe 42, and air distribution pipe 43 facilitates the discharge of outside air into multiple connecting pipes 44. The bottom end of aeration pipe 45 communicates with the interior of connecting pipe 44 and can be discharged through aeration port 46 on the outer wall of aeration pipe 45, facilitating the aeration treatment of municipal sewage inside aeration treatment tank 1.

Piston head 479 can block one side of aeration port 46, facilitating the adjustment of the size of aeration port 46 for exhaust according to aeration requirements, thereby improving the aeration effect.
[0024] Example 2:
[0025] like Figure 1-4 As shown, a purification mechanism 5 is provided on the right side of the top of the support plate 3. The purification mechanism 5 includes a medicine tank 51. The bottom of the medicine tank 51 is fixedly installed on the right side of the top of the support plate 3. The medicine tank 51 contains ozone disinfectant. A medicine pump 52 is fixedly installed on the right side of the top of the support plate 3. A first delivery pipe 53 is fixedly installed at the input end of the medicine pump 52. An electromagnetic control valve 54 is installed on the first delivery pipe 53. One end of the first delivery pipe 53 is fixedly installed on the lower left side inside the medicine tank 51.

When the fixed plate 476 moves vertically, the fixed plate 476 can stretch the bottom end of the telescopic hose 55 through the second drug delivery pipe 56. By opening the electromagnetic control valve 54, the ozone disinfectant inside the drug tank 51 is extracted using the drug pump 52 and the first drug delivery pipe 53. The ozone disinfectant is then discharged into multiple nozzles 57 through the telescopic hose 55 and the second drug delivery pipe 56. The ozone disinfectant is sprayed into the sewage inside the aeration treatment tank 1 using the multiple nozzles 57, which facilitates disinfection treatment during the aeration process.
[0027] In summary, as Figure 1-4As shown, in operation, this municipal wastewater treatment equipment uses a blower 41 to discharge air through an air supply pipe 42, a distribution pipe 43, and a connecting pipe 44 into multiple aeration pipes 45, and then through an aeration port 46 to discharge air into the aeration treatment tank 1, forming a large number of bubbles for aeration. At this time, the motor 471 and the worm gear reducer 472 drive the lead screw 473 to rotate, which in turn moves the connecting plate 474 inside the mounting cover 47. The connecting plate 474 then moves the fixing plate 476 via the connecting rod 475. The four corners of the top of the fixing plate 476 also move the guide rods 477 inside the support plate 3. The fixed plate 476 slides vertically, and the bottom of the fixed plate 476 simultaneously drives the piston head 479 to move inside the aeration pipe 45 through the straight rod 478. The piston head 479 is moved to one side of the aeration port 46 to block the aeration port 46. The size of the aeration port 46 can be adjusted according to the aeration needs to improve the aeration effect. Then, the electromagnetic control valve 54 is opened, and the ozone disinfectant inside the agent tank 51 is drawn into the nozzle 57 through the agent pump 52, the first agent delivery pipe 53, the telescopic hose 55 and the second agent delivery pipe 56. The ozone disinfectant is then sprayed into the sewage inside the aeration treatment tank 1 through the nozzle 57 to facilitate the disinfection and sterilization of the sewage.
