Problems solved by technology

my country is a large agricultural country with a huge amount of agricultural residues, which are widely distributed. According to statistics, the annual output of agricultural straw and livestock manure is about 700 million tons and 3 billion tons of livestock and poultry manure. The processing and utilization will cause serious environmental pollution and huge waste of resources
[0003] At present, the treatment of agricultural residues is still in the stage of passive disposal, and the resource utilization of its components is still in the initial stage, and no systematic and large-scale industrial chain has been formed.

Embodiment 1

[0024] see figure 1 , a method for utilizing all components of agricultural residues, comprising the steps of:

[0025] 1) Putting the straw into the component decomposition and enrichment device 1 for pretreatment, and separating it through the solid-liquid separator 2 to obtain high-concentration liquid carbohydrates and hemicellulose, solid cellulose and lignin;

[0026] 2) The high-concentration liquid carbohydrates and hemicellulose obtained in step 1) are directly transported to the automatic power modular anaerobic fermentation device 4 for full liquid phase fermentation to obtain biogas and biogas slurry, and the generated biogas is stored in the automatic power In the air storage bag above the modular anaerobic fermentation device, the biogas slurry is returned to the automatic power modular anaerobic fermentation device as a fermentation starting liquid for recycling;

[0027] 3) Mix the solid cellulose and lignin 62% obtained in step 1) with 10% wheat bran, 26% saw...

Abstract

The invention relates to a full-component utilizing method for agricultural residue. The full-component utilizing method for agricultural residue specifically comprises the following steps that strawis pretreated, and after decomposing, high-concentration liquid carbohydrate and hemicellulose and solid cellulose and lignin are obtained through separation; the high-concentration liquid carbohydrate and hemicellulose are subjected to full-liquid phase fermentation, and marsh gas and biogas slurry are obtained; the solid cellulose and lignin are mixed with edible fungus culture medium ingredients to produce edible fungus sticks; the edible fungus sticks are used for edible fungus production, and edible fungus and abandoned fungus sticks are obtained; a part of the abandoned fungus sticks andearthworm culture base stock are mixed, and earthworms are bred; the left abandoned fungus sticks and agricultural residue are smashed to be fermented, marsh gas, a liquid concentrated solution and biogas residue are obtained, and the biogas residue is used for producing nursery seedling plates; and the liquid concentrated solution and the high-concentration liquid carbohydrate and hemicelluloseare subjected to full-liquid phase fermentation. By means of the full-component utilizing method for the agricultural residue, the rural ecological environment can be improved to a great degree, and harmless and recycling treatment of the agricultural residue is truly achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural waste reuse, in particular to a method for utilizing all components of agricultural residues. Background technique [0002] Agricultural residues refer to the general term for crop straws, livestock and poultry manure, tail vegetables, tree branches and leaves, and waste residues in the processing of agricultural and sideline products. my country is a large agricultural country with a huge amount of agricultural residues, which are widely distributed. According to statistics, the annual output of agricultural straw and livestock manure is about 700 million tons and 3 billion tons of livestock and poultry manure. The processing and utilization will cause serious environmental pollution and huge waste of resources. [0003] At present, the treatment of agricultural residues is still in the stage of passive disposal, and the resource utilization of its components is still in its infancy, and no ...
