Description

Technical Field

[0001] The utility model relates to the technical field of biological trickling filtration equipment, in particular to a biological trickling filtration deodorizing device for a municipal sewage plant. Background Art

[0002] The biotrickling filter absorbs odors generated by sewage treatment plants through the early cultivation of microbial strains. These elements include sulfur, hydrogen, nitrogen and other gases, which generally have a bad odor. Biological strains can effectively absorb and decompose them, and at the same time, these gases are eventually converted into carbon dioxide and water to achieve the purpose of deodorization and purification. In order to reduce the NIMBY effect of sewage treatment plants and the impact on surrounding residents, ensure a good working environment and comply with relevant environmental protection regulations, deodorization design should be carried out in sewage treatment plants.

[0003] For example, the utility model patent with publication number CN221854363U discloses a biological trickling filter sewage deodorization device, which includes a fixed ring fixed in the middle of the inner cavity of an outer shell; a biological treatment component, including a grille plate abutting the upper end of the fixed ring, the upper end of the grille plate is coiled with a carbon filler chain composed of a plurality of carbon filler blocks passed through a rubber tube, and the surface of the rubber tube is provided with a plurality of openings for water outlet, at least two biological treatment components are stacked on each other so that the upper biological treatment component is located in the middle and upper part of the outer shell; a spray component, including a fixed rod fixed on both sides of the inner wall of the upper shell, a sealing sleeve fixed in the middle of the fixed rod, and a hollow sprinkler disc for spraying is rotatably provided in the inner cavity of the lower end of the sealing sleeve. The device has the advantages of increasing the sealing performance of the replacement carbon filler structure and the biological trickling filter, increasing the utilization rate of the storage device space and making the carbon filler better recycled. The spray device of the device does not need to be powered by electricity to rotate, effectively reducing the use cost of the device. However, there is a problem in that when removing the carbon filler layer, the upper shell needs to be lifted first and then the support rod needs to be manually pulled upward, which will cause the upper shell to be obstructed when replacing the carbon filler layer, and finally lead to time-consuming and labor-intensive replacement of the carbon filler layer. For this reason, we propose a biological trickling filter deodorization device for municipal sewage treatment plants. Utility Model Content
