Example Embodiment

[0037] Embodiment 1, a kind of concentrated biogas slurry, the raw material component is:

[0038] 60kg of water, 17.5kg of organic matter, 8.5kg of amino acids, 5kg of minerals and 0.4kg of vitamins;

[0039] The mass ratio of starch, cellulose and sugar is 10:3:1.

Example Embodiment

[0040] Embodiment 2, the described concentrated biogas slurry, the raw material components are: moisture 65 kg, organic matter 20 kg, amino acid 7 kg, mineral substance 3 kg and vitamin 0.7 kg;

[0041] The mass ratio of starch, cellulose and sugar is 12:2:3.

Example Embodiment

[0042] Embodiment 3, the described concentrated biogas slurry, the raw material components are: moisture 70 kg, organic matter 15 kg, amino acid 10 kg, mineral 4 kg and vitamin 1 kg;

[0043] The mass ratio of starch, cellulose and sugar is 13:1:3.

[0044] The preparation methods of the concentrated biogas slurry of Preparation Example 1, Example 2 and Example 3 are the same, and the preparation method is:

[0045] (1) Fermentation

[0046] The livestock manure is collected in the anaerobic fermentation tank for anaerobic fermentation, and biogas, biogas residue and biogas slurry are produced;

[0047] (2) Deodorization

Abstract

The invention discloses concentrated biogas slurry and a preparation method thereof. The concentrated biogas slurry is prepared from, by weight, 60-70 parts of water, 15-20 parts of organic matters, 7-10 parts of amino acids, 3-5 parts of mineral substances and 0.4-1 part of vitamins, wherein the organic matters include starch, cellulose and saccharides, and the mass ratio of starch to cellulose to saccharides is (10-13):(2-4):(1-3). The biogas slurry is subjected to concentration, matching addition and other technological treatment, the contained water is greatly lowered, the contents of amino acids and microelements are increased, and then the requirement for nutrient substances of agricultural plants can be met.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a concentrated biogas slurry and a preparation method thereof. [0002] technical background [0003] At present, there are many types of fertilizers used in agricultural planting. According to relevant information and market surveys, inorganic chemical fertilizers account for 80% of the usage. The so-called inorganic chemical fertilizers, commonly known as chemical fertilizers, are the most abundant in the market. (N) Fertilizer, common such as urea. Phosphorus (p) fertilizer, common such as superphosphate. Potassium (k) fertilizer, common such as potassium nitrate, etc. [0004] In agricultural planting, the long-term and large-scale use of chemical fertilizers has caused many disadvantages: [0005] One is the problem of soil compaction. There are very few active ingredients in chemical fertilizers that can be absorbed and utilized by plants, such as urea. Ur...
