Problems solved by technology

The principle of chemical deodorization is to absorb by reaction, or the strong oxidant oxidizes and decomposes the malodorous components, but the chemical deodorization reaction is not complete, or there is a new pollution problem in the residue

[0071] The present embodiment refers to the preparation method of the microbial inoculant of Example 1, the difference is only in:

[0072] In step (6), the culture of the bacillus described in step (2), the culture of the acidic thiobacillus acidophilus in step (3), the culture of the described Acinetobacter baumannii YYF1 in step (4) and the culture of Rhodopseudomonas paluscans in step (5) are uniformly mixed according to volume percentages of 50%, 10%, 20% and 20%.

Embodiment 3

[0074] The present embodiment refers to the preparation method of the microbial inoculant of Example 1, the difference is only in:

[0075] In step (6), the culture of the bacillus described in step (2), the culture of the acidic thiobacillus acidophilus in step (3), the culture of the described Acinetobacter baumannii YYF1 in step (4) and the culture of Rhodopseudomonas palustris in step (5) are uniformly mixed according to volume percentages of 90%, 5%, 2% and 3%.

Abstract

The invention relates to the technical field of microorganisms, in particular to a microbial preparation as well as a preparation method and application thereof in deodorization. The microbial preparation comprises the following strains: bacillus subtilis, bacillus pumilus, thiobacillus acidophilus, acinetobacter baumannii YYF1 and rhodopseudomonas palustris; the acinetobacter baumannii YYF1 is preserved in the China Center for Type Culture Collection, the preservation number of the acinetobacter baumannii YYF1 is CCTCC NO: M2021609, and the preservation time of the acinetobacter baumannii YYF1 is May 24, 2021. In the microbial preparation, multiple enzymes secreted through cooperation of multiple bacteria have a synergistic effect in the aspect of odor treatment, soluble odor components can be effectively degraded, the solubility of non-water-soluble odor components can be promoted through metabolites and exopolysaccharides, and the odor emission concentration is reduced.

Description

technical field [0001] The invention relates to the technical field of microorganisms, in particular to a microbial preparation, a preparation method thereof and an application in deodorization. Background technique [0002] Odor pollution is one of the seven major environmental hazards recognized in the world. Common odor pollutants include hydrogen sulfide, ammonia, trimethylamine, methyl mercaptan, dimethyl disulfide, carbon disulfide, etc. Hydrogen sulfide and ammonia gas are easier to remove, while the malodorous components of organic waste gas, due to the difference in olfactory threshold, many components are difficult to dissolve in water or lack the existence of degrading microorganisms, which will cause sensory discomfort to the human body after discharge. If the pollutants are not treated, the diffusion of tail gas will directly harm human health, especially the stench emitted in domestic sewage treatment plants and sewage pipelines. Therefore, the odor problem h...
