Description

Technical Field

[0001] The utility model relates to the technical field of vertical multi-stage deodorizing biological filter tanks, in particular to a vertical multi-stage deodorizing biological filter tank. Background Art

[0002] In odor treatment, the more mature biological deodorization method is biological filtration, and the more mature equipment is the deodorization biological filter. Biological deodorization mainly uses microorganisms to deodorize, and transforms odorous substances through the physiological metabolism of microorganisms, so that the target pollutants are effectively decomposed and removed.

[0003] A vertical multi-stage deodorizing biological filter disclosed in the Chinese utility model patent application disclosure CN218944752U has the advantages of recycling water to save resources and convenient maintenance and replacement of biological filter layers, but the vertical multi-stage deodorizing biological filter still has disadvantages: first, the vertical multi-stage deodorizing biological filter adopts three different biological fillers directly placed in series inside the same net box to filter the odor in sequence. In actual use, there may still be a problem that the resistance of the system is doubled due to the series arrangement of the three fillers, thereby affecting the filtering efficiency of the odor; second, the vertical multi-stage deodorizing biological filter is provided with a recycling mechanism to recycle and recycle water. In actual use, water is only directly input into the interior of the filter tank to perform preliminary deodorization treatment on the odor. The utilization rate of water during use may not be very high, which is easy to cause waste of resources. Utility Model Content
