Problems solved by technology

However, composting has the disadvantages of large area, long processing cycle, and odor. At present, many places have applied a new environmentally friendly treatment method, that is, on-site biochemical treatment, and pour the kitchen waste into the biochemical treatment machine on the spot. Food waste can be degraded into powdery residue by adding c

Example Embodiment

[0025] Before implementing the present invention, the food residues, slops, and non-edible animals and plants discarded edible oils and oil-water mixtures produced in hotels, guesthouses, catering industries, schools, government agencies, and unit canteens can be mechanically processed. After separation and dehydration, high-temperature thermophilic bacteria are added to carry out fermentation in an organic waste biochemical processor for 1-2 days, and the residue produced after fermentation is autoclaved and pulverized into the following powder required by the invention.

[0026] The present invention is specifically a kind of organic-inorganic compound fertilizer granules, in parts by weight,

[0027] Including 25-45 parts of powder, which is produced by microbial treatment of kitchen waste,

[0028] 25-35 parts of plant ash, which is made from crop stalks after being burned, dried, pulverized and sieved;

[0029] 5-10 parts of binder, and the rest are one or more of nitrog...

Abstract

The invention discloses organic-inorganic compound fertilizer particles and a preparation method thereof. The organic-inorganic compound fertilizer particles comprise the following components in parts by weight: 25-45 parts of powder, 25-35 parts of plant ash and 5-10 parts of adhesive and the balance of one or several of a nitrogen fertilizer, a phosphate fertilizer, a potash fertilizer and trace-element fertilizers, wherein the powder is generated by performing microbiological treatment on kitchen wastes; the plant ash is prepared by combusting crop straws, drying, milling and screening. The organic-inorganic compound fertilizer particles are granular; because the inorganic fertilizer is coated with the fertilizer particles, and the plant ash has a good adsorption effect, so that the nutrient release speed is low, and the organic-inorganic compound fertilizer particles have a certain slow release benefits.

Description

technical field [0001] The invention relates to an organic-inorganic compound fertilizer granule fertilizer produced by using kitchen waste, specifically, the residue of kitchen waste after microbial fermentation treatment is washed with water to desalt, high-temperature sterilization, composting, drying and crushing, and then mixed with plant ash and urea , monoammonium phosphate, potassium chloride, attapulgite, and EM bacteria solution are mixed and disc granulated to form organic-inorganic compound fertilizer particles, which belongs to the field of environment and resources. Background technique [0002] At present, with the rapid development of my country's economy, the continuous expansion of urbanization scale and the high concentration of urban population, the continuous improvement of people's consumption level, the development of my country's catering industry has a large scale, fast delivery, and the production of kitchen waste is also increasing. Increasingly, th...
