Description

Technical Field

[0001] The utility model relates to the technical field of aerated biological filter tanks, in particular to a sewage treatment aerated biological filter tank capable of accelerating reaction efficiency. Background Art

[0002] Aerated biological filter is developed from trickling filter and belongs to the category of biofilm method. This process combines multiple purification functions such as filtration, adsorption and biological metabolism, making it small in size, less land occupation, high treatment efficiency, good effluent quality, simple process, convenient operation and management, and can save the secondary sedimentation tank. Most of the current aerated biological filters increase the contact area between oxygen and sewage during aeration, thereby accelerating the reaction efficiency between the biofilm generated on the filler and the sewage. However, in actual use, in order to meet the design requirements for air pressure, it is difficult for the air nozzles of the aeration pipe to be dense and dense, and oxygen cannot achieve a relatively uniform contact with the filler layer, so the reaction efficiency is not very high. For this reason, we propose a sewage treatment aerated biological filter that can accelerate the reaction efficiency to solve the above problems. Utility Model Content

The bubbles generated by the gas output by the air nozzle 4 are dispersed by the forward and reverse rotation of the dispersing blade 13. At the same time, the dispersed bubbles can be more evenly and symmetrically contacted with the filler layer located on the filter cotton plate 16 under the drive of the water flow. After the gas and the filler layer are evenly contacted, the reaction area of ​​the biofilm is increased, thereby accelerating the reaction efficiency.

The front end of the aeration tank 1 is fixedly connected with a shell 8 near the lower side. A chute 9 is provided at the inner bottom of the shell 8. A rack 10 is slidably connected inside the chute 9. There is a certain distance between the left and right ends of the chute 9 and the rack 10.

[0024] Working principle:

[0025] When in use, after the sewage is discharged into the aeration tank 1 through the water inlet 17, the gas is input into the main aeration pipe 2 and the branch aeration pipe 3 through the aeration mechanism, and then sprayed out through the air nozzle 4 for aeration treatment. At the same time, by opening the cylinder 12, its output end drives the connecting piece 11 to make the rack 10 slide left and right repeatedly, and the rack 10 slides left and right to drive the gear 7 to rotate forward and reversely, and the gear 7 drives the rotating shaft 5 to rotate forward and reversely through the forward and reverse installation of the gear 7, thereby driving the breaking blade 13 to continuously rotate forward and reversely, and then the bubbles generated by the gas output by the air nozzle 4 are broken by the forward and reverse rotation of the breaking blade 13. At the same time, driven by the water flow, the dispersed bubbles can be more evenly and symmetrically contacted with the packing layer on the filter cotton plate 16. After the gas is evenly in contact with the packing layer, the reaction area of ​​the biofilm is increased, thereby accelerating the reaction efficiency. At the same time, the sewage is treated more evenly, the overall purification effect is improved, and the number of times aeration needs to be repeated is reduced. Further, through the through hole 14, the bubbles are broken more finely, and large bubbles are easier to break and disperse, thereby improving the use effect of the present technical solution.
