Embodiment 1

[0023] In terms of weight, get 7.5 kg of urea and 8 g of commercially available n-butylthiophosphoric triamide, pour them into a blender and mix well, set aside. Then take 70 kg of waste decolorizer, 20 kg of sheep manure, and 7.508 kg of urea and urease inhibitor mixture mixed above, and input them into a mixer and mix them evenly to obtain organic fertilizer powder, which is then granulated to obtain 97.508 kg of granulated organic fertilizer. Fat. The organic fertilizer contains a mass fraction of total nutrients (nitrogen + phosphorus pentoxide + potassium oxide) of 5.02% (calculated on an oven-dried basis), a mass fraction of organic matter (calculated on an oven-dried basis) of 76.5%, and moisture (fresh sample ) is 4.4%, pH value is 7.6, in line with the technical indicators of the industry standard NY525-2012 of the Ministry of Agriculture of the People's Republic of China: organic matter mass fraction (based on drying basis) ≥ 45, total nutrients (nitrogen + phosphoru...

Embodiment 2

[0025] By weight, get 9.5 kilograms of urea and 15 grams of commercially available n-butylthiophosphoric triamide, pour them into a blender and mix evenly, set aside. Then take 80 kg of waste decolorizer, 30 kg of sheep manure, and 9.515 kg of urea and urease inhibitor mixture mixed above, and input them into a mixer and mix them evenly to obtain organic fertilizer powder, which is then granulated to obtain 119.515 kg of granulated organic fertilizer. Fat. The organic fertilizer contains a mass fraction of total nutrients (nitrogen + phosphorus pentoxide + potassium oxide) of 5.14%, an organic matter mass fraction of 72.91%, and moisture (fresh sample) ) is 5.15%, and the pH value is 7.6, which is in line with the technical indicators of the industry standard NY525-2012 of the Ministry of Agriculture of the People's Republic of China.

Embodiment 3

[0027] By weight, get 8.5 kilograms of urea and 15 grams of commercially available n-butylthiophosphoric triamide, pour them into a blender and mix well, set aside. Then take 70 kg of waste decolorizer, 30 kg of sheep manure, and 8.515 kg of the above mixed urea and urease inhibitor mixture, input them into a mixer and mix them evenly to obtain organic fertilizer powder, and then granulate to obtain 108.515 kg of granulated organic fertilizer. Fat. The organic fertilizer contains a mass fraction of total nutrients (nitrogen + phosphorus pentoxide + potassium oxide) of 5.09%, an organic matter mass fraction of 71.13%, and moisture (fresh sample) ) is 5.58%, and the pH value is 7.6, which meets the technical indicators of the industry standard NY525-2012 of the Ministry of Agriculture of the People's Republic of China.

Abstract

The invention relates to an organic fertilizer based on a waste decolorizing agent. The formula of the organic fertilizer contains the following components in parts by weight: 70-80 parts of a waste decolorizing agent, 20-30 parts of sheep manure, 7.5-9.5 parts of urea and 0.008-0.015 part of a urease inhibitor, wherein the waste decolorizing agent contains the following components by weight percent: 0.36%-0.41% of total nitrogen, 0.79%-0.83% of P2O5, 0.35%-0.40% of K2O, and organic carbon more than or equal to 55%. The preparation method comprises the following steps: pretreatment of the waste decolorizing agent, pretreatment of the sheep manure, pretreatment of the urea, premixing, mixing and granulation. The waste decolorizing agent is taken as the main raw material of the organic fertilizer, so that the serious consequence of soil pollution or spontaneous combustion caused due to the arbitrary stacking of the waste decolorizing agent is prevented; the sheep manure, the urea and theurease inhibitor are scientifically and reasonably matched, so that the relative balance of the microorganisms, carbon nitrogen ratio and released carbon and nitrogen of the organic fertilizer is realized; and production equipment is low in investment, easy to operate, low in production cost and good in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers, and in particular relates to the preparation of organic fertilizers using waste decolorizers and a preparation method thereof. Background technique [0002] Waste decolorizer is the leftover waste produced in the process of vegetable oil refining, which generally accounts for about 3% of the oil refining amount. In recent years, the annual consumption of edible oil in my country is about 30 million tons, which means that about 900,000 tons of waste decolorizers are produced every year. Depending on the decolorization process, the general waste decolorizer contains 20%-30% oil. The waste decolorizing agent can spontaneously ignite at a relatively high temperature, and if it is discharged directly without treatment, it will pollute the environment. At present, large and medium-sized oil refining enterprises all use recycled oil to process and utilize it as auxiliary materials such as ...
