This puts forward higher requirements for the design, transformation and operation optimization of new and existing urban wastewater treatment plants. The wastewater treatment process adopted by new urban wastewater treatment plants must not only have high SS and COD removal capabilities, but also high-efficiency nitrogen and phosphorus nutrient removal capabilities. Most existing urban wastewater treatment plants are facing the upgrading and transformation of wastewater treatment processes and operation optimization.

[0003] According to the disclosed sewage treatment enhanced nitrification device based on biochemical cotton filler and its use method (publication number: CN114506920B): it includes a sewage treatment biochemical reaction tank, a biochemical cotton filler sheet ring group, and a motor ratchet group. The sewage treatment biochemical reaction tank consists of a tank body, an activated sludge and sewage mixing layer, and an aeration pipeline system; the biochemical cotton filler sheet ring group includes ultrasonically welded ring-shaped biochemical cotton filler sheets and ratchet chains at the upper and lower ends of the ring-shaped biochemical cotton filler sheets; and the motor ratchet group is supported and fixed in the sewage treatment biochemical reaction tank by multiple groups of polypropylene ratchets with upper and lower fixed sleeves of the motor shaft, and the motor bracket of the motor ratchet group is fixed to the top of the sewage treatment biochemical reaction tank.

[0004] In the above application, through the mutual cooperation between the biochemical cotton packing sheet and the ratchet chain assembly, it is difficult to solve the function of cleaning the biochemical cotton packing sheet after multiple filtrations, resulting in the accumulation of debris on the surface of the biochemical cotton packing sheet causing blockage.

[0017] 1. The present invention cooperates with each other among the first electric telescopic rod, the hydraulic rod and the adjusting plate of the flow control mechanism. When sewage needs to be treated, the staff first starts the first electric telescopic rod to make the push rod push the force rod before releasing the sewage. The hydraulic rod of the hydraulic cylinder extends outward by the pressure of the liquid inside the hydraulic cylinder. The extension of the hydraulic rod drives the adjusting plate to move. Then the staff can adjust the flow of the water inlet pipe according to work needs. When the force rod is not stressed, the elasticity of the reset spring drives the adjusting plate to reset.

At this time, the sewage flows out through the delivery pipe to the top of the filtering biochemical cotton for re-filtration. At the same time, when the baffle moves upward, the air inlet is opened to provide oxygen to the inside of the treatment chamber, so that the oxygen microorganisms on the filtering biochemical cotton grow, and the oxygen microorganisms degrade the organic matter in the sewage. The treated clean water flows out of the treatment chamber through the outlet pipe. This design not only achieves the effect of multiple filtration treatment of the sewage, but also promotes the effect of microbial growth on the degradation of sewage, thereby reducing the organic load of the sewage.

[0019] 3. The present invention cooperates with the second electric telescopic rod, scraper and collection box of the cleaning mechanism. When the processing chamber is used up, the staff can start the second electric telescopic rod to move the scraper from right to left to clean the debris on the surface of the filter biochemical cotton. The debris cleaned by the scraper falls into the collection box through the waste outlet. After the collection is completed, the collection box can be pulled out of the collection tank by the handle for processing. This design achieves the effect of cleaning the surface of the filter biochemical cotton and effectively avoids blockage and reduced degradation efficiency.

[0039] A cleaning mechanism 6 is provided inside the processing chamber 1, and the cleaning mechanism 6 includes a second electric telescopic rod 61, the bottom of the second electric telescopic rod 61 is fixedly connected to the top of the processing chamber 1, and the telescopic end of the second electric telescopic rod 61 is fixedly connected to a connecting rod 62, and the side of the connecting rod 62 penetrates the side of the processing chamber 1 and is slidably connected to the side of the processing chamber 1, and the end of the connecting rod 62 away from the telescopic end of the second electric telescopic rod 61 is fixedly connected to a scraper 63, a waste outlet 64 is provided on the side of the partition 54, and a collecting groove 65 is provided on the side of the processing chamber 1, and a collecting box 66 is slidably connected inside the collecting groove 65, and a handle 67 is fixedly connected to the side of the collecting box 66.

[0041] A specific application of this embodiment is: when sewage needs to be treated, the staff first starts the first electric telescopic rod 41 before releasing the sewage, and the telescopic end of the first electric telescopic rod 41 moves from right to left, and the telescopic end of the first electric telescopic rod 41 moves from right to left, driving the push rod 42 to move from right to left. During the movement of the push rod 42 from right to left, the force-bearing rod 44 of the hydraulic cylinder 43 is pushed, and the force-bearing rod 44 retracts into the inside of the hydraulic cylinder 43 under the thrust. At this time, the hydraulic rod 45 of the hydraulic cylinder 43 extends outward due to the pressure of the liquid inside the hydraulic cylinder 43, and the hydraulic rod 45 extends outward to drive the adjustment plate 46 to move, so that the staff can adjust the flow of the water inlet pipe 2 according to work needs, and when the force-bearing rod 44 is not under force, the elasticity of the reset spring 47 drives the adjustment plate 46 to reset.

The counterclockwise rotation of the output shaft of the motor 51 drives the rotating shaft 52 to rotate counterclockwise. The counterclockwise rotation of the rotating shaft 52 drives the rotating plate 53 to rotate counterclockwise. The rotating plate 53 rotates counterclockwise to push the sewage inside the treatment chamber 1. At this time, the sewage flows out through the conveying pipe 511 to the top of the filtering biochemical cotton 55 for re-filtration. At the same time, the counterclockwise rotation of the rotating shaft 52 drives the rotating rod 56 to rotate counterclockwise. During the counterclockwise rotation of the rotating rod 56, the moving rod 58 will be indirectly knocked. The moving rod 58 moves upward, driving the baffle 59 to move upward. When the baffle 59 moves upward, the air inlet 57 is opened to provide oxygen to the inside of the treatment chamber 1 The air causes the oxygen microorganisms on the filter biochemical cotton 55 to grow, and the oxygen microorganisms degrade the organic matter in the sewage. The treated clean water flows out of the treatment chamber 1 through the outlet pipe 3. When the treatment chamber 1 is used up, too much debris is accumulated on the surface of the filter biochemical cotton 55 inside the treatment chamber 1. In order to avoid blockage and reduced degradation efficiency, the staff can start the second electric telescopic rod 61 at this time. The telescopic end of the second electric telescopic rod 61 moves from right to left. The telescopic end of the second electric telescopic rod 61 moves from right to left and drives the scraper 63 to move from right to left through the connecting rod 62. During the movement of the scraper 63 from right to left, the debris on the surface of the filter biochemical cotton 55 is cleaned. The debris cleaned by the scraper 63 falls into the collection box 66 through the waste outlet 64. After the collection is completed, the collection box 66 can be pulled out of the collection tank 65 by the handle 67 for treatment.
