Embodiment

[0036] Example: In this example, the special microbial organic fertilizer for corn is carried out in a double-coordinated bio-organic fertilizer production line, using a large-scale mixing and crushing unit with a volume of 1000Kg, using 194 tons of food waste and 48 tons of fermented raw fertilizer produced by ingredients, and adding in proportion : 4.8 tons of urea, 3.36 tons of calcium magnesium phosphate fertilizer, 2.4 tons of potassium chloride, 0.96 tons of manganese sulfate, 0.48 tons of zinc sulfate heptahydrate, 2.4 tons of sodium silicate aqueous solution, 48Kg of sodium molybdate, 38.4Kg of copper sulfate, 48Kg of biological agents, Add 48Kg of carrier auxin mixture and 48Kg of soil conditioner. The amount of raw fertilizer is 500Kg at a time. The operation process is as follows:

[0037] Preparation of sodium silicate slurry: watering amount=(raw fertilizer 48t+urea 4.8t+calcium magnesium phosphate fertilizer 3.36t+potassium chloride 2.4t+manganese sulfate 0.96t+...

Abstract

The invention relates to a method for preparing a fertilizer by mineralized fermentation through rejecting heavy metal in kitchen waste and decomposing dioxin, which can be used for producing a microbial organic fertilizer by element coordination processes twice based on rejecting the heavy metal in kitchen waste slurry, separating the dioxin by emulsified oil, dissolving and decomposing the dioxin by an organic solvent generated by deep anaerobic fermentation, decomposing the dioxin by biological phagocytosis, desalting by bentonite and preparing an organic original fertilizer by carrying out high-temperature mineralization reaction, fermenting and killing harmful bacteria and pathogenic microorganism. The method is a precedent for rejecting the heavy metal in the kitchen waste and decomposing the dioxin, a set of scheme with less investment and low cost can be provided for safely placing the kitchen waste, and the waste resources are effectively utilized, so that new economic value and social wealth can be created; when the kitchen waste is used for preparing the fertilizer, waste water, waste gas and waste residue are not discharged, so that the secondary pollution possibly caused by landfill, incineration and compost for the soil, the atmosphere and the water resource can be avoided, and the ecological environment is protected; and a high-quality fertilizer is provided for the agriculture, the yield and the quality of agricultural products are improved, and the agricultural sustainable development can be supported by the method.

Description

technical field [0001] The invention relates to a method for making fertilizer by using organic materials, belonging to the technical field of agricultural organic fertilizer production, in particular to a method for making fertilizer by removing heavy metals from kitchen waste, decomposing dioxin, mineralizing and fermenting. Background technique [0002] The status quo of kitchen waste disposal: According to related reports, my country produces 60 million tons of kitchen waste annually. With the acceleration of urbanization and the rapid expansion of urban population, it is estimated that kitchen waste is still growing at a rate of 30% every year. The main components of food waste include rice and flour food residues, vegetables, animal and vegetable oils, meat and bones, etc.; in terms of chemical composition, there are starch, cellulose, protein, lipids and inorganic salts. Its main features: First, it has a high moisture content, most of which accounts for 80-90% of the...
