Embodiment 1

[0028] A microbial preparation for municipal solid waste deodorization, which is prepared according to the following process:

[0029] Aspergillus niger seed liquid (1 × 10 8 cfu / ml) and Trichoderma viride seed solution (1×10 8 cfu / ml) were mixed according to the volume ratio of 1:2, and then transferred to the fermenter for 24 hours according to the inoculation amount of 10% volume ratio to obtain the mixed fermentation broth of Aspergillus niger-Trichoderma viride;

[0030] The culture medium components of the fermenter are: molasses 10wt%, cornstarch 3.5wt%, glucose 2.0wt%, sodium dihydrogen phosphate 0.2wt%, magnesium sulfate 0.02wt%, manganese sulfate 0.01wt%, and the balance is water, pH is 7.0;

[0031] Rhodococcus, Candida utilis, Nocardia eutrophicum and Paracoccus denitrifica were cultured on slant, shake flask seeds and fermenter respectively to obtain Rhodococcus fermentation broth, Candida utilis fermentation broth, coral color Fermentation broth of Nocardiella...

Embodiment 2

[0037] A microbial preparation for municipal solid waste deodorization, which is prepared according to the following process:

[0038] Aspergillus niger seed liquid (1 × 10 8 cfu / ml) and Trichoderma viride seed solution (1×10 8 cfu / ml) were mixed according to the volume ratio of 1:2, and then transferred to the fermenter for 24 hours according to the inoculation amount of 10%, to obtain the mixed fermentation liquid of Aspergillus niger-Trichoderma viride;

[0039] The culture medium components of the fermenter are: molasses 10wt%, cornstarch 3.5wt%, glucose 2.0wt%, sodium dihydrogen phosphate 0.2wt%, magnesium sulfate 0.02wt%, manganese sulfate 0.01wt%, and the balance is water, pH is 7.0;

[0040] Rhodococcus, Candida utilis, Nocardia eutrophicum and Paracoccus denitrifica were cultured on slant, shake flask seeds and fermenter respectively to obtain Rhodococcus fermentation broth, Candida utilis fermentation broth, coral color Fermentation broth of Nocardiella and Paracocc...

Embodiment 3

[0046] The microbial preparation deodorizing effect test prepared by the embodiment of the present invention 1:

[0047] Mix 1200kg of rotten municipal solid waste evenly, divide it into 6 parts on average, each part is 200kg, place them in 6 airtight rooms of the same size, numbered 1-6 respectively, first add 10 times the weight to the microbial preparation of the present invention The water is made into bacterium liquid, adds respectively in No. 1-5 municipal solid waste with the weight ratio of 0.01%, 0.02%, 0.03%, 0.04%, 0.05%, No. 6 municipal solid waste does not add any bacterial agent. After 72 hours, take samples at different collection points around the garbage, and measure NH 3 、H 2 S removal rate, odor concentration. NH 3 Using sodium hypochlorite-salicylic acid spectrophotometry, H 2 S adopts polyvinyl alcohol ammonium phosphate absorption-methylene blue colorimetric method, and the odor concentration is measured by XP-329IIIR aroma and odor concentration dete...

Abstract

The invention belongs to the technical field of microorganism and discloses a microbial preparation for deodorizing municipal solid waste. The microbial preparation is prepared in the following process: step 1) preparation of aspergillus niger-trichoderma viride mixed fermentation liquor; step 2) preparation of a composite bacteria liquid; step 3) preparation of a crosslinking agent; and step 4) concentration, crosslinking, washing and drying. The preparation process of the microbial preparation is simple, low in cost, good in deodorization effect, ecological, environment-friendly and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of microbes, in particular to a microbiological preparation for deodorizing urban domestic garbage. Background technique [0002] With the continuous development of the urbanization process, more and more people gather in the city, and the municipal solid waste is also increasing at a rate of more than 10% per year. The generation of municipal solid waste and the environmental pollution it brings have attracted people's attention, especially at the garbage collection point in the city center and the transfer station of urban solid waste. It will have a certain impact on the quality of life of residents and the local ecological environment. If the management of municipal solid waste collection and transfer is not standardized, it will seriously damage the ecology of the city and cause people's psychological unhappiness. [0003] At present, the commonly used methods at home and abroad include adsorption met...
