Novel biological soil deodorization filter tank and deodorization process

Abstract

The invention relates to a novel biological soil deodorization filter tank and a deodorization process. Odor in a deodorization area is collected through an odor collection pipeline, the odor is pumped to an air inlet pipeline by a high-pressure fan to enter the bottom of the filter tank, the odor is filtered through a bottom filler layer and an upper filler layer in sequence from bottom to top, after the malodorous gas is filtered by the bottom filler layer, most of the malodorous gas is adsorbed and decomposed, the residual gas is converged in a gap between the bottom filler layer and the upper filler layer to ensure uniform distribution of the gas, then the malodorous gas is filtered by the upper filler layer, and the malodorous gas is completely decomposed by microorganisms in the filler after passing through the upper filler layer. Thus, odor treatment is realized, gas discharge reaches the standard, the odor is filtered in a layered manner in the filter tank, the filtering effect is good, the uppermost layer of the filter tank is the organic mixed soil, the temperature is set to be 5-40 DEG C suitable for the survival of microorganisms, and the proportioned organic mixed soil has higher air permeability, is not easy to harden, contains more organic matters, and is more beneficial to survival and reproduction of the microorganisms.

Description

technical field [0001] The invention relates to the technical field of soil filters, and more specifically relates to a novel biological soil deodorization filter and a deodorization process. Background technique [0002] At present, biological deodorization filters on the market mainly include two categories, one is biological filter, and the other is biological soil filter. Biological filter deodorization technology is a treatment system that uses light domesticated microorganisms On the active biological medium prepared in a certain proportion, through the adsorption, absorption and degradation of malodorous substances by microorganisms, the malodorous substances are absorbed and converted into non-toxic CO 2 、H 2 O, H 2 SO 4 , NHO 3 Such as simple inorganic substances, the bioactive medium has a large porosity and surface area, and a certain humidity is maintained through controlled circular spraying, while the medium carries a large number of domesticated microbial ...

Problems solved by technology

[0004] The invention provides a new type of biological soil deodorization filter and deodorization process to solve the problem that the existing soil filter technology has poor filtering effect, and the soil filter layer is easy to harden after a period of use, and the resistance will gradually increase, so it needs to be refurbished regularly. The problem that bacteria are not easy to survive and reproduce
