Problems solved by technology

Although the above-mentioned patent can convert food waste into bio-organic fertilizer and insect protein in a short period of time (3-7 days) by using soldier flies with bright spots, but the role of microorganisms has not been fully exerted during the conversion process
Although the kitchen waste bio-organic fertilizer produced by the above process can meet the national organic fertilizer standards in terms of organic matter and nitrogen, phosphorus and potassium, the number of microorganisms in the fertilizer, especially the number of functional microorganisms that have the functions of promoting plant growth and disease resistance Still insufficient, technical level still has room for improvement

Embodiment 1

[0023] The method for producing functional microbial organic fertilizer by using light-spotted flat-horned soldier flies and microorganisms to transform kitchen waste according to the present invention comprises the following steps:

[0024] The first step, food waste pretreatment

[0025] The collected food waste with a water content of 80% is sorted to remove inorganic substances such as metals and plastics, and sent to the pulverizer to be crushed to a particle size of 1mm. The grease is separated and processed (can be processed into biodiesel), and the remaining materials The slurry is collected into the mixer through pipelines and mud pumps, and the water content is adjusted to 85%. Yeast powder (Angel Yeast) is added in an amount of 0.1% by mass to volume, and food waste is added in an amount of 0.02% by mass. Treat deodorizing bacteria (Su Kehan, SKHZYE-RBFW-04), anaerobic fermentation at 25°C for 48 hours before use;

[0026] The second step is to prepare the Bacillus...

Abstract

The invention discloses a method for producing functional microbial organic fertilizer by using light-spotted flat-horned soldier flies and microorganisms to transform kitchen waste. Firstly, the kitchen waste is processed into a slurry, and yeast and deodorizing bacteria are inserted for anaerobic fermentation. The cultured and activated Bacillus megaterium was then cultured and fermented into a fermentation liquid; the slurry was placed in a reactor, and the 3rd instar soldier fly larva was inserted into a certain amount of inoculum, and after cultivation, the Bacillus megaterium fermentation liquid was sprayed in proportion, After continuous fermentation, the insect material mixture is obtained. After sieving, the flathorned soldier fly body and bio-organic fertilizer are collected, and the body is dried to become feed. The organic fertilizer is packaged and stored after passing the quality inspection. The invention has short processing period, green and energy-saving, and the whole processing process is basically carried out in a closed state, without obvious air pollution; the use of kitchen waste as the raw material of organic fertilizer can significantly reduce the production cost, and at the same time, the use of organic fertilizer can also reduce the The application of chemical fertilizers improves farmers' benefits and reduces environmental pollution.

Description

technical field [0001] The invention relates to the technical field of biology and fertilizer processing, in particular to a method for producing functional microbial organic fertilizer by utilizing light-spotted soldier flies and microorganisms to transform kitchen waste. Background technique [0002] Kitchen waste includes food waste, catering leftovers, food processing waste, non-edible animal and vegetable oils and various oil-water mixtures from families, schools, institutions, public canteens, and catering industries. It is an important part of urban domestic waste. Taking Beijing as an example, more than 1,600 tons of kitchen waste is generated every day; it is estimated that 1.34 billion people in the country will generate 134,000 tons of kitchen waste per month. Random stacking and illegal disposal of these kitchen wastes not only waste resources, but also pollute the environment, endanger public health and food safety, and go against our country's concept of creati...
