Livestock and poultry manure composite sulfuric acid type furfural residue organic fertilizer and preparation method thereof

Abstract

The invention belongs to the technical field of cultivation. The invention discloses a livestock and poultry manure composite sulfuric acid type furfural residue organic fertilizer and a preparation method thereof. The livestock and poultry manure composite sulfuric acid type furfural residue organic fertilizer is prepared from livestock and poultry manure, furfural residues, 2-5 parts of lactobacillus acidophilus liquid, 2-4 parts of bacillus subtilis, 0-3 parts of bacillus amyloliquefaciens, 2-5 parts of bacillus megatherium, 1-3 parts of bacillus cereus and 0-2 parts of a mould liquid. Theorganic fertilizer disclosed by the invention can improve soil and improve organic matters; one-step deodorization is achieved, the efficiency reaches 85% or above, and the air quality is improved; the temperature rises quickly and reaches 70 DEG C or above within 2-3 days, moisture in livestock and poultry manure and furfural residues can be removed quickly, fermentation is conducted for about 15days, and the moisture content of the mixed material reaches about 35%; meanwhile, environmental pollution sources of the two wastes are eliminated; the escherichia coli killing rate of the fermentedproduct exceeds 99.99%, and heavy metals are solidified.

Description

technical field [0001] The invention belongs to the technical field of breeding, and in particular relates to a livestock and poultry manure composite sulfuric acid type furfural slag organic fertilizer and a preparation method thereof. Background technique [0002] At present, with the increasing scale of the breeding industry, the waste generated by pig farms is also polluting the environment more and more. The typical ones are wastewater pollution, livestock and poultry manure treatment and odor problems generated during the breeding process. Among them, livestock and poultry manure has gradually become the focus of attention due to the large amount of emissions and the difficulty of treatment. Livestock and poultry manure contains a large amount of ammonia, hydrogen sulfide, urate, indole, amine, pathogenic bacteria and insect eggs, etc. If the manure of livestock and poultry is discharged randomly without treatment, it will easily cause the above harmful substances to e...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problem existing in the existing technology is: the organic matter of the existing livestock and poultry manure is insufficient, and materials with high organic matter content such as straw and rice bran must be added. These added materials need to be decomposed into small molecular sugars under the action of exogenous microorganisms. Substances can start the fermentation process, so it takes a long time, generally about 5 days before the temperature rises to about 50°C; at the same time as fermentation, pig manure has a high water content and a long water removal cycle, and a large amount of water will appear in this process. The generation of foul-smelling gas, especially the ammonia-nitrogen-based gas is very easy to cause secondary pollution to the environment; the current use of furfural slag is mainly mixed with some components, and it is easy to cause the decomposition time of furfural slag in the soil without fermentation treatment. If it is too long, it will be difficult for plants to absorb; in addition, the current furfural slag is generally highly acidic, which has a certain acidifying effect on the soil, and long-term use will lead to soil acidification
