Kitchen waste bio-organic fertilizer and preparation method thereof

Abstract

The invention discloses a kitchen waste bio-organic fertilizer. The bio-organic fertilizer is prepared from the following raw materials in parts by mass: 600-800 parts of straw, 300-400 parts of kitchen waste, 400-600 parts of cattle and sheep manure and 4-5 parts of a complex microbial inoculant, wherein the straw is composed of, by mass, 15% of rice straw, 16% of wheat straw, 14% of cornstalks,18% of corncobs, 18% of oat hulls and 19% of stalkofgrain, and the complex microbial inoculant comprises bacteria for cellulose decomposition, fungi for decomposition of cellulose and hemicellulose, actinomycetes for cellulose decomposition and microbial bacteria for lignin oxidation. The invention further discloses a preparation method of the kitchen waste bio-organic fertilizer. According to theinvention, carbon and nitrogen source treatment is optimized, parasitic source breeding is reduced, a composting environment is improved, composting efficiency is improved, odor emission is weakened,and organic nutrient loss is reduced.

Description

technical field [0001] The invention relates to the technical field of bio-organic fertilizers, in particular to a kitchen waste bio-organic fertilizer and a preparation method thereof. Background technique [0002] Nowadays, the problem of soil pollution in our country is increasing year by year. The residues of organic pollutants such as pesticides are serious, and the quality of cultivated land soil environment is worrying. The use of organic fertilizers is an important way to achieve the sustainable development of modern agriculture. [0003] The main components of food waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc. In terms of chemical composition, there are starch, cellulose, protein, lipids and inorganic salts, which have become a major source of urban non-point source pollution. public nuisance. For this type of food waste, it is generally put into garbage bags and thrown away directly, and processed through ...

AI Technical Summary

Problems solved by technology

At present, there are usually physical methods, chemical methods, biological methods, etc. in the treatment process of food waste. Specific treatment technologies include landfill, incineration, composting, fermentation, etc. The traditional method of using food waste to produce organic fertilizer is mainly composting and fermentation. The existing technology for producing organic fertilizer from food waste can easily breed a large number of flies, blood-sucking midges, parasites, etc. during the composting process, making the composting environment harsh and posing certain hazards to environmental sanitation and personnel health; Kitchen waste contains proteins, lipids and other components, and it takes a long time to ferment to decompose, which will emit a lot of odor, which will affect the lives of the staff and the surrounding people; moreover, the incomplete decomposition will lead to the loss of a large amount of organic nutrients, which will affect the quality of organic fertilizers.
