Problems solved by technology

[0005] With the development of the national economy, waste disposal has been put on the agenda of governments at all levels. Traditional waste disposal has problems such as high operating costs, small output, and no output from landfill. Even if the government invests in construction, the annual High operating costs will also become a huge burden on local governments
Landfill and incineration are the main methods of garbage disposal in my country at present. Garbage landfill needs to occupy a large amount of land. In the era of urbanization and industrialization, land resources are in a hurry. This road is not a shortcut, and it is prone to secondary pollution. waste of precious resources

Embodiment 1

[0034] Example 1 Processing of kitchen waste

[0035] Collect kitchen waste (animal waste from the vegetable market, including chicken, duck, fish viscera, skin, hair);

[0036] Cultivate microorganisms: Pick yeast (Pichia pastoris) from the inclined plane, recover in conventional medium, perform first-level culture, and expand culture before use.

[0037] Take the kitchen waste and the Saccharomyces cerevisiae after expanding the culture (the number of viable bacteria is not less than 2.0×10 6 per mL) according to the mass ratio of 2:1300, and left to ferment at 38°C to obtain the processed food waste product.

Embodiment 2

[0038] Example 2 Processing of kitchen waste

[0039] Collect kitchen waste (garbage from various slaughterhouses, including discarded internal organs, skins and fur);

[0040] Culture of microorganisms: pick Saccharomyces cerevisiae from the inclined plane, resuscitate in conventional culture medium, perform first-level culture, and expand culture before use.

[0041] Take the kitchen waste and the Saccharomyces cerevisiae after expanding the culture (the number of viable bacteria is not less than 2.0×10 6 per mL) according to the mass ratio of 1:1500, and left to ferment at 38°C to obtain the processed food waste product.

Embodiment 3

[0042] Example 3 Processing of kitchen waste

[0043] Collect kitchen waste (leftovers from various food processing factories and spoiled and spoiled meat products);

[0044] Culture of microorganisms: pick Saccharomyces cerevisiae from the inclined plane, resuscitate in conventional culture medium, perform first-level culture, and expand culture before use.

[0045] Take the kitchen waste and the Saccharomyces cerevisiae after expanding the culture (the number of viable bacteria is not less than 2.0×10 6 per mL) according to the mass ratio of 3:1000, and left to ferment at 40°C to obtain the processed food waste product.

Abstract

The invention relates to the field of biological processing, and in particular relates to a processing method of kitchen wastes and the application of a processed product as an organic fertilizer. The processing method is simple, and the kitchen wastes are effectively utilized. A kitchen waste processed product is rich in nutrients and can be used for preparing the organic fertilizer. Moreover, the invention also provides the organic fertilizer. The organic fertilizer comprises the kitchen waste processed product and acceptable elements in the fertilizer. By applying the organic fertilizer containing the kitchen waste processed product, the number of root nodules of summer soybeans can be effectively increased, the chlorophyll content, leaf nitrogen content, net photosynthetic rate and yield of the summer soybeans are improved, and increase of the farmer income is promoted.

Description

technical field [0001] The invention relates to the field of biological processing, in particular to a processing method of kitchen waste and the application of the processed product as organic fertilizer. Background technique [0002] In the urban process, garbage, as a product of metabolism, used to be a burden on urban development, and many cities in the world are surrounded by garbage. Nowadays, garbage is considered to be the most potential and inexhaustible "urban mineral deposit" as "misplaced resources". This is the in-depth understanding of garbage, and it is also an inevitable requirement for urban development. [0003] Domestic waste refers to various wastes discharged by residents in urban waste, and refers to solid waste generated in daily life or activities that provide services for daily life and solid waste that is regarded as domestic waste according to laws and administrative regulations. Divided into four categories: recyclable waste, kitchen waste, hazar...
