Embodiment 1
[0024] A special microbial strain for processing steel slag, vinegar grains, and weathered coal, the microbial strains are Hansenula anomaly, Hansenula laminatus, Pichia powdery, Saccharomyces cerevisiae, Geotrichum candidum, Bacillus subtilis subsp. The mass ratio of Bacillus licheniformis, Bacillus megaterium, Lactobacillus acidophilus and Streptomyces luteus is 2:2:2:2:1:5:3:2:1:4. The microbial strains are taupe and loose. The total number of effective viable bacteria of the microorganism strains is ≥600 million / g, the moisture content is ≤20%, and the pH value is 6.8. Each of the microbial carriers is diatomite and rice bran that have been crushed through a 80-mesh sieve and sterilized at high temperature, and the mass ratio of diatomite to rice bran is 2:1.
[0025] The above-mentioned preparation method of special microbial strains for processing steel slag, vinegar grains and weathered coal comprises the following steps:
[0026] (1) Select microorganisms, respective...

Abstract
The invention relates to a special microorganism strain for processing steel slag, vinegar residues and weathered coal and a preparation method thereof. The microorganism strain comprises hansenula anomala, film press hansenula, pichia farinose, saccharomyces cerevisiae, geotrichum candidum, bacillus subtilis withered grass subspecies, bacillus licheniformis, bacillus megaterium, lactobacillus acidophilusis and streptomyces microflavus in the mass ratio of 2:2:2:2:1:5:3:2:1:4. The preparation method comprises the steps of microorganism selection, activation, one-class expansion, second-class swinging bed amplification, carrier adsorption, preparation, low-temperature drying, detection, metering and packaging. The invention can harmlessly process the steel slag, vinegar residues and weathered coal, neutralizes the strong alkalinity of the steel slag by utilizing the organic acid generated in the process of fermentation, forms an organic acid metal complex, reduces the fixation of nutrients, improves the effective utilization ratio of the nutrients, efficiently utilizes organic sources, such as steel slag, vinegar residues, weathered coal, and the like, and reduces environmental pollution.
Description
technical field [0001] The invention belongs to a microbial strain, in particular to a special microbial strain for processing steel slag, vinegar grains and weathered coal and a preparation method thereof. Background technique [0002] Microbial technology is an applied technology that combines the principles of biology and engineering. It extracts microbial strains from soil and water in nature, passes various rigorous tests in the laboratory to determine their ability to decompose various organic matter, and then selects practical strains for cultivation and propagation, and reaches commercial scale. application to solve a specific problem. Each strain can produce one or several types of biological enzymes that degrade a certain type of specific organic matter, and different types of strains work together to effectively decompose complex organic matter into simple small molecules, and finally transform them into non-toxic Harmless product. [0003] Steel slag is waste ...
