Abstract
The invention discloses a carbon sequestration composting method, which comprises the following steps: carrying out humidity adjustment on the raw materials; adding microbial strains and stirring to ensure that the microbes are fully and uniformly contacted with the raw materials; mechanically making the stirred raw materials into a conical column, and making the top of the conical column into a pool shape; covering with three-proofing cloth, compacting and sealing the bottom with soil, and pressurizing the top to make the cloth fully contact with the raw material, so as to condense the gas generated by fermentation and prevent gas leakage; sealing and keeping for more than 6 months to convert carbon dioxide generated by fermentation into environmentally-friendly humic acid substances, and reducing the temperature of the pile to be close to normal temperature to be used for soil improvement. Compared with the prior art, the invention has the advantages that: fully and effectively carry out harmless treatment on animal and plant solid wastes, and reduce carbon emission and environmental pollution; the product after long-term fermentation is easier to be absorbed by plants, becomes a safe functional fertilizer, has good applicability, low price, environmental protection and convenient popularization.
Description
Technical Field
The invention relates to the field of environmental protection, in particular to a carbon-fixing composting method.
Background
At present, composting produced by organic fertilizers is a main method for innocent treatment and resource utilization of raw materials such as animal and plant solid wastes and the like. In the traditional production of organic fertilizer, the mixed raw materials are added into microbial strains to be stacked and fermented in rows, the whole production process is exposed in the air, and gases such as carbon dioxide generated by fermentation and the like all enter the atmosphere, so that the carbon dioxide emission of the atmosphere is increased; the composting method needs to turn the pile for many times, and the used machinery also consumes energy, which is not beneficial to the country to realize the goals of carbon peak reaching and carbon neutralization.
Disclosure of Invention
The invention aims to solve the technical problems that the method adopted by the current organic fertilizer production is open compost turning, all the generated gas (carbon dioxide, hydrogen sulfide, ammonia gas and the like) is discharged into the atmosphere, the environment is polluted, and the carbon emission is increased
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a carbon sequestration composting method comprises the following steps:
step one, carrying out humidity adjustment on raw materials;
step two, adding microbial strains for stirring, and enabling the microbes to be in full and uniform contact with the raw materials;
step three, mechanically making the stirred raw materials into a conical cylinder, and making the top of the conical cylinder into a water pool shape;
covering with a three-proofing cloth, compacting and sealing the bottom with soil, and pressurizing the top to ensure that the cloth is fully contacted with the raw materials, so that the cloth has the effects of condensing gas generated by fermentation and preventing gas leakage;
and step five, sealing and keeping for more than 6 months to convert carbon dioxide generated by fermentation into environmentally-friendly humic acid substances, and reducing the temperature of the pile to be close to normal temperature to be used for soil improvement.
Compared with the prior art, the invention has the advantages that: fully and effectively carry out harmless treatment on animal and plant solid wastes, and reduce carbon emission and environmental pollution; the product after long-term fermentation is easier to be absorbed by plants, becomes a safe functional fertilizer, has good applicability, low price, environmental protection and convenient popularization.
Furthermore, the raw material is animal and plant solid waste.
Detailed Description
In specific implementation, the carbon sequestration composting method comprises the following steps:
step one, carrying out humidity adjustment on raw materials;
step two, adding microbial strains for stirring, and enabling the microbes to be in full and uniform contact with the raw materials;
step three, mechanically making the stirred raw materials into a conical cylinder, and making the top of the conical cylinder into a water pool shape;
covering with a three-proofing cloth, compacting and sealing the bottom with soil, and pressurizing the top to ensure that the cloth is fully contacted with the raw materials, so that the cloth has the effects of condensing gas generated by fermentation and preventing gas leakage;
and step five, sealing and keeping for more than 6 months to convert carbon dioxide generated by fermentation into environmentally-friendly humic acid substances, and reducing the temperature of the pile to be close to normal temperature to be used for soil improvement.
The raw materials are animal and plant solid wastes.
The working principle of the invention is as follows: according to the invention, animal and plant solid wastes and other raw materials are mixed and then added into microbial strains to be sealed by adopting a three-proofing cloth, the microorganisms are absorbed and converted in the pile body to carry out nutrient cycle by utilizing gases such as carbon dioxide and the like generated by the symbiosis of the interiors of the microorganisms and fermentation, the effects of gas emission reduction and carbon fixation are realized, and the temperature in the pile body is close to the normal temperature after six months of sealing, so that the method is used in agricultural production.
The specific method comprises the following steps: 1) adjusting the dryness and humidity of raw materials such as animal and plant solid wastes; 2) adding microbial strains and stirring to ensure that the microbes are fully and uniformly contacted with the raw materials; 3) mechanically making the stirred raw materials into a conical column, and making the top of the conical column into a pool shape; 4) covering with three-proofing cloth, compacting and sealing the bottom with soil, and pressurizing the top to make the cloth fully contact with the raw material, so as to condense the gas generated by fermentation and prevent gas leakage; 5) sealing and keeping for more than 6 months to convert carbon dioxide generated by fermentation into environmentally-friendly humic acid substances, and reducing the temperature of the pile to be close to normal temperature to be used for soil improvement.
Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made in the above embodiments by those of ordinary skill in the art without departing from the principle and spirit of the present invention.
