Description

Technical Field

[0001] The utility model relates to the technical field of waste gas deodorization, in particular to a soil filter biological deodorization device. Background Art

[0002] The soil biofilter deodorization process is a safe and reliable treatment method that uses the soil layer as a microbial carrier. It has high deodorization efficiency and can be organically integrated with the surrounding environment to become a part of the landscape. The principle is that the odor is collected by the collection system and then sent to the soil deodorization system. The water in the soil absorbs and dissolves water-soluble odorous gases (such as amines, hydrogen sulfide, low-level fatty acids, etc.), the soil surface physically adsorbs non-water-soluble odors, and the soil biological community absorbs and degrades them, decomposing odorous substances into CO2, H2O, SO4 2- 、NO 3- And other non-toxic and harmless simple inorganic substances, thereby removing pollutants.

[0003] When the existing soil filter biological deodorization is in use, the exhaust gas is discharged from the bottom of the filter through the air distribution pipe. The position of the exhaust holes from the air distribution pipe to the surface is fixed, so that the exhaust gas can only be moved out from a specific position, resulting in the microbial utilization efficiency at this location being higher than that at other locations. When the treatment efficiency of the microorganisms at this location is saturated, the deodorization effect of the exhaust gas will decrease, and when the exhaust gas is not introduced, the liquid inside the filter can easily carry the medium into the air distribution pipe, which can easily cause the dirt inside the air distribution pipe to clog the pores.
