Description

technical field [0001] The invention relates to a fertilizer starter and its preparation method and application, in particular to a fertilizer starter capable of utilizing industrial waste residues, its preparation method and its application in the fermentative production of organic fertilizers, organic-inorganic compound fertilizers and biological fertilizers. Background technique [0002] There are many key pollutant discharge enterprises in the fermentation industry, such as biopharmaceutical enterprises (such as enterprises producing antibiotics, etc.), food fermentation enterprises (such as enterprises producing monosodium glutamate, citric acid, alcohol, etc.). In the process of industrial fermentation production, microorganisms not only produce a variety of beneficial metabolites through reproduction and fermentation, but also produce a large amount of waste residue, such as the mycelium produced in the production of antibiotics and the bacteria residue formed by some ...

AI Technical Summary

Problems solved by technology

In the process of industrial fermentation production, microorganisms not only produce a variety of beneficial metabolites through reproduction and fermentation, but also produce a large amount of waste residue, such as the mycelium produced in the production of antibiotics and the bacteria residue formed by some underutilized raw materials , if they are directly discharged into the environment, they will cause pollution to the environment, and the treatment of the resulting pollution will require high costs

But in fact, a lot of resources are wasted in treating the fermentation industry waste residue in this way, because the nutrients contained in it are very comprehensive. According to research, the fermentation industry residue is rich in crude protein, crude fat, crude fiber, phosphorus, calcium, nitrogen-free Extracts (such as glucose, cellulose, hemicellulose, etc.) and other beneficial nutrients are good sources of nutrition for organisms, but they also contain some residual antibiotics, organic acids, alcohol, etc. Therefore, the fermentation industry These fermentation industry waste residues should be comprehensively utilized first, and then pollution control

[0003] At present, the methods of utilizing fermentation industry waste residue at home and abroad are as follows: one is the physical method, which is to bake the bacterial residue with a converter to make it easy to store and can be used as a feed additive, but its palatability is poor, and the amount of addition is small, and The harmful substances remaining therein will also cause food safety problems; the second is the chemical method, which is to add quicklime, sodium hydroxide, and calcium carbonate to the bacteria residue for processing, and it can be used as fertilizer or feed after processing. The problem that this method exists is that only Added chemical reagents, but the nutrient composition in the fungus residue has not changed, therefore, plant, animal are difficult for absorbing; The 3rd, mixing method, is to add molasses in the fungus residue, makes it become high-energy feed, but does not fundamentally like this On the one hand, solve the existing problems of the first two methods; the fourth is the traditional natural fermentation method, the bacteria residue can be made into fertilizer through the fermentation of the aerobic bacteria carried by itself, but the fermentation speed is slow, the output is low, and the product quality cannot be obtained. Effective and stable control limits the commercialization of fermented products and cannot be popularized and applied; the fifth is the strain fermentation method, which uses selected flora and composts at high temperature. After the bacteria residue is fermented, its nutrients are easily absorbed. It can be made into fertilizer or feed, but the flora used is relatively fixed, and the product cannot be properly adjusted according to the test, and the one-time fermentation method is adopted, the strain has poor tolerance to harmful substances in the fungus residue, and the utilization of the fungus residue The rate is low, generally below 50%
