Problems solved by technology

[0003] At present, a lot of food waste is transported back by farmers and directly used to feed pigs or fish. However, this untreated food waste has many potential safety hazards on the food chain and tables, as well as secondary environmental pollution. Local governments have issued relevant prohibition measures and advocated harmless resource utilization

Embodiment

[0036] Example: Disposal of kitchen waste in a university cafeteria

[0037] The food waste in a university canteen is usually fish, meat, bone and other wastes, vegetables, rice noodles and other wastes, and fish, meat, bones and other wastes as supplementary waste. About 800kg of various organic food wastes are produced every day. For this kind of garbage, the implementation plan of treatment is: use the food waste to degrade at normal temperature, which is a complex probiotic microbial flora that integrates multiple functions, such as EM bacteria, lactic acid bacteria, yeast, bacillus, bismuth Mycobacteria, mineral carriers, etc. The usage method is calculated in parts by weight: step 1: compound probiotic microorganisms account for 2 parts; step 2: kitchen waste accounts for 55 parts; step 3: clean water accounts for 43 parts. Put the above steps 1, 2 and 3 into the hydraulic disintegration tank 1 for disintegration, mixing, preliminary degradation and thickening, and the...

Abstract

The invention particularly relates to a method and device for converting kitchen waste into bio-organic fertilizer. According to the preparing method, the kitchen waste, composite prebiotic microorganism bacteria and water are mixed to form the fertilizer, the composite prebiotic microorganism bacteria account for 1-5 parts, the kitchen waste accounts for 55-65 parts, and the water accounts for 30-44 parts, the kitchen waste, the composite prebiotic microorganism bacteria and the water are placed into a hydraulic power beating tank, a first motor drives beating impellers to carry out continuous smashing, a first pump body conveys the mixture into a degrading and fermenting tank, then a second motor in the degrading and fermenting tank drives a stirrer to carry out continuous stirring, and the bio-organic fertilizer is obtained after the mixture reacts. The preparing method has the advantages that the composite prebiotic microorganism bacteria are utilized for converting the kitchen waste into the fertilizer, soil is improved through fertilizer activation, and the fertilizer provides various kinds of nutrition needed by crops for a long term, has the effects of nitrogen fixation, phosphate solubilizing and potassium releasing, and can activate and decompose ineffective potassium and ineffective phosphorus in the soil into available phosphorus and quick-acting potassium which can be absorbed and utilized by plants, and obstruct the plants from absorbing harmful heavy metal.

Description

technical field [0001] The invention relates to a preparation method and a production device for converting kitchen waste into bio-organic fertilizer. Background technique [0002] With the continuous improvement of people's living standards, the amount of domestic waste also increases, and kitchen waste is an important part of domestic waste. How to better resource disposal of these garbage is an urgent problem everywhere. [0003] At present, a lot of food waste is transported back by farmers and directly used to feed pigs or fish. However, this untreated food waste has many potential safety hazards on the food chain and tables, as well as secondary environmental pollution. Local governments have introduced relevant prohibition measures and advocated harmless resource utilization. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a preparation method and production dev...
