Method for producing organic-inorganic complex fertilizer by using mycelium

Abstract

The invention discloses a method for producing organic-inorganic compound fertilizer by using mycelium, which includes the following steps: selecting mycelium and protein slag in the solid waste generated from microbial fermentation, wherein, the mycelium occupies 60 percent of the total weight of the two; drying and dehydrating the two after mixing the two and then being crumbled into power; selecting inorganic fertilizers which are one or a plurality of combinations of nitrogenous fertilizer, phosphate fertilizer, potash fertilizer and / or medium and minim nutritive element fertilizer; selecting itaconic acid production tail washings as granulating substance; and mixing and evenly mixing the mixture obtained from the steps, spraying granulation to obtain compound fertilizer particulate matters. The method for preparing organic-inorganic compound fertilizer has the advantages of little invest, low energy consumption, quick returns and the like, and also has social and economical value of reducing pollution, protecting environment, saving energy and the like.

Description

technical field

[0001] The invention relates to a production method of organic-inorganic compound fertilizer, in particular to a method for producing organic-inorganic compound fertilizer by using organic wastes such as mycelium and protein residue produced by microbial fermentation in an organic acid factory. Background technique

[0002] At present, production waste such as mycelium and protein slag produced by the organic acid production industry is acidic due to a small amount of organic acid, and generally cannot be used directly, and is usually incinerated or buried as solid waste. This treatment method has not only increased the pressure on environmental protection, but also wasted high-quality organic sources (mainly composed of protein).

[0003] The Eleventh Five-Year Plan made a comprehensive deployment for the development of circular economy and the construction of a conservation-oriented society in my country in the next five years, clearly stating: "Insist on e...
