Problems solved by technology

[0004] The purpose of the present invention is to address the deficiencies in the prior art, to provide a compound microbial deodorant for livestock and poultry manure and sewage and a preparation method thereof. The chemical deodorization effect in the deodorant is insufficient and incomplete, or the biological method cannot fundamentally solve the problem of livestock manure and sewage odor, and the deodorization efficiency is not ideal. The production and fermentation process of the deodorant is simple, and the microbial flora easy to cultivate

Embodiment 1

[0028] A compound microbial deodorant of livestock and poultry manure and sewage, which is prepared by mixing the following raw materials in parts by weight:

[0029] Inoculate the strains of Lactobacillus, Bacillus subtilis, Saccharomyces cerevisiae, and Streptomyces into the activation medium with a volume ratio of about 20% and shake the flask for activation culture, and inoculate the cultured strains into the fermenter Carry out expanded culture, then according to the weight ratio of 20 parts of Lactobacillus, 30 parts of Bacillus subtilis, 25 parts of Saccharomyces cerevisiae and 25 parts of Streptomyces, the strains obtained by the expanded culture are mixed to obtain the compound microorganism of livestock and poultry manure and sewage Deodorant.

Embodiment 2

[0031] A compound microbial deodorant of livestock and poultry manure and sewage, which is prepared by mixing the following raw materials in parts by weight:

[0032] Inoculate the strains of Lactobacillus, Bacillus subtilis, Saccharomyces cerevisiae, and Streptomyces into the activation medium with a volume ratio of about 20% and shake the flask for activation culture, and inoculate the cultured strains into the fermenter Carry out expanded culture, then according to the weight ratio of 15 parts of Lactobacillus, 35 parts of Bacillus subtilis, 20 parts of Saccharomyces cerevisiae, and 30 parts of Streptomyces, the strains obtained by the expanded culture are mixed to obtain the compound microorganism of livestock and poultry manure and sewage Deodorant.

Abstract

The invention relates to a livestock excrement and sewage compound microbial deodorizer and a preparation method thereof. The livestock excrement and sewage compound microbial deodorizer is mainly prepared by mixing raw materials including, by weight, 10-20 parts of spore bacteria, 15-25 parts of lactic acid bacteria, 10-20 parts of microzyme and 15-25 parts of actinomycetes. Each type of bacteria are inoculated in a shake flask containing a culture medium to be cultured in an activated mode, the bacteria cultured in the activated mode are inoculated into a fermentation tank to be cultured in an expanded mode, and all types of bacterium liquid obtained through expanded culture are mixed according to the proportion to prepare the livestock excrement and sewage deodorizer. The deodorizer is used for livestock excrement and sewage; compared with the prior art, the deodorizer is simple in preparation method, short in technological process, low in cost and convenient to use, only needs to be stored at the room temperature and is long in validity period.

Description

technical field [0001] The invention relates to a compound microbial deodorizing agent of livestock and poultry manure and sewage and a preparation method thereof. Background technique [0002] With the rapid development of scale and intensification of livestock and poultry farms, the concentrated discharge of livestock and poultry manure, sewage and sewage has brought huge pollution to the environment, and the process of stacking livestock and poultry manure, sewage and sewage also pollutes the soil , water, air, resulting in serious deterioration of the surrounding environment. Under the premise that the country advocates environmental protection, livestock and poultry manure, sewage and sewage treatment have become environmental problems that need to be solved urgently. [0003] At present, deodorants are mainly divided into physical deodorants, chemical deodorants, microbial deodorants, and plant deodorants. Physical deodorants mainly use absorbents to absorb odorous s...
