Abstract

The invention relates to the field of a deodorization filling material, in particular to a deodorization microbial filling material and a preparation method thereof. The deodorization microbial filling material is prepared from a pressure-resistant porous composite filling material substrate and deodorization strains fixed to inside pores and surfaces of the composite material substrate; the deodorization goal is achieved by using the physical adsorption of the reticular structure pores in the filling material and the degradation effect of the microbes in the pores and on the surfaces of the filling materials. The characteristics of uniform particle diameter, high pressure resistance, high porosity, low density, high surface roughness and high deodorization microbial activity are realized;the problems of easy compaction, low adsorption efficiency on pollution gas, regeneration difficulty and the like of the existing waste gas biological purification device can be solved.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a deodorizing microbial filler for waste gas treatment. Background technique [0002] VOCs is the general term for volatile organic compounds. These organic compounds are widely used in petrochemical, printing, baking varnish, coating, electronic components and other industries. They are mainly used as solvents and volatilize into the air after use. VOCs are not only irritating to humans, but most of them are toxic to internal organs and the nervous system. For example, benzene series compounds can cause damage to the central nervous system, and will harm the blood and hematopoietic organs after entering the human body; Situation; olefins and some aromatic compounds volatilize into the air, and under the action of light, they will chemically react with nitrogen oxides to form photochemical smog, causing secondary pollution. [0003] At present, activated carbon adsor...
