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

Embodiment 1

[0062] The present embodiment provides microbial bacterial agents, including Bacillus subtilis, Bacillus pumilus, Acidophilus thiobacillus, Acinetobacter baumannii YYF1 and Rhodopseudomonas palustris, in terms of viable count, Bacillus subtilis, Bacillus pumilus , Acidithiobacillus, Acinetobacter baumannii YYF1 and Rhodopseudomonas palustris in a ratio of 5:5:2:4:4.

[0063] The preparation method of the microbial bacterial agent of the present embodiment, comprises the steps:

[0064] (1) Bacillus subtilis is fermented with high-density liquid to obtain fermentation liquid, and the fermentation liquid is spray-dried to make spore content as high as 2×10 11 CFU / g super-concentrated Bacillus subtilis powder; Bacillus pumilus is fermented with high-density liquid to obtain fermentation broth, and the fermentation broth is spray-dried to make spore content up to 2×10 11 CFU / g super-concentrated Bacillus pumilus powder; the composition of the fermentation medium is: glucose 10g / L...

Embodiment 2

[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, a preparation method thereof and an application in deodorization. Microbial preparations, including the following strains: Bacillus subtilis, Bacillus pumilus, Acidophilus thiobacillus, Acinetobacter baumannii YYF1 and Rhodopseudomonas palustris; the Acinetobacter baumannii YYF1 is preserved in the China Center for Type Culture Collection , the deposit number is: CCTCC NO: M2021609, and the deposit date is: May 24, 2021. In the microbial preparation of the present invention, various enzymes secreted by multi-bacteria have a synergistic effect on odor treatment, can effectively degrade soluble odor components, metabolites and extracellular polysaccharides can promote the solubility of water-insoluble odor components, Reduce the concentration of odor emissions.

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...
