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

[0035] Example 1 Processing of food waste

[0036] Collect food and kitchen waste (animal waste in the vegetable market, including the offal, skin and hair of chicken, duck, and fish);

[0037] Cultivation of microorganisms: pick the yeast (Pichia pastoris) from the slant, revive it in the conventional medium, first-level culture, and expand the culture before use.

[0038] Take food waste and expand the cultured yeast (Pichia pastoris, the number of live bacteria is not less than 2.0×10 6 Pieces / mL) Mix according to the mass ratio of 2:1300, and leave it to ferment at 38°C to obtain processed food waste products.

Embodiment 2

[0039] Example 2 Processing of food waste

[0040] Collect food wastes (waste from various slaughterhouses, including discarded internal organs, skins, and hairs);

[0041] Cultivation of microorganisms: pick the yeast (Pichia pastoris) from the slant, revive it in the conventional medium, first-level culture, and expand the culture before use.

[0042] Take food waste and expand the cultured yeast (Pichia pastoris, the number of live bacteria is not less than 2.0×10 6 Pieces / mL) Mix according to the mass ratio of 1:1500, and leave to ferment at 38°C to obtain processed food waste products.

Embodiment 3

[0043] Example 3 Processing of food waste

[0044] Collect food wastes (leftovers from various food processing plants and spoiled and spoiled meat products);

[0045] Cultivation of microorganisms: pick the yeast (Pichia pastoris) from the slant, revive it in the conventional medium, first-level culture, and expand the culture before use.

[0046] Take food waste and expand the cultured yeast (Pichia pastoris, the number of live bacteria is not less than 2.0×10 6 Pieces / mL) Mix according to the mass ratio of 3:1000, and leave it for fermentation at 40°C to obtain processed food waste products.

Abstract

The invention relates to the field of biological processing and particularly relates to a processing method of kitchen wastes and an application of a kitchen waste processed product as an organic fertilizer. The processing method is simple and capable of effectively utilizing kitchen wastes. A prepared kitchen waste processed product is rich in nutrient and can be used for preparing the organic fertilizer. In addition, the invention provides an organic fertilizer comprising the kitchen waste processed product and elements which can be accepted in the fertilizer. By applying the organic fertilizer containing the kitchen waste processed product, the root nodule number of summer soybeans can be effectively increased, the chlorophyll content, leaf blade nitrogen content and net photosynthetic rate of the summer soybeans can be increased, the yield of the summer soybeans can be increased, and the farmer income can be increased.

Description

Technical field [0001] The invention relates to the field of biological processing, in particular to a method for processing food and kitchen waste and the application of the processed product as organic fertilizer. Background technique [0002] In the urban process, waste as a metabolic product used to be a burden for urban development. Many cities in the world have been surrounded by waste. Nowadays, garbage is considered to be the most potential for development and the never-ending "urban mineral deposits" are "misplaced resources". This is a deepening and deepening of the knowledge of garbage and an inevitable requirement for urban development. [0003] Domestic garbage refers to all kinds of wastes discharged by residents in urban garbage, 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 by laws and administrative regulations. Divided into four categories: recyclable garbage, k...
