Embodiment 1

[0014] Embodiment 1: A method for producing organic fertilizer with plant ash and furfural slag from a biological power plant, collecting furfural slag and plant ash from a biological power plant, and air-drying to make its moisture content 15-20%. Mix furfural slag and plant ash from biological power plants at a weight ratio of 2.7-3:2.2-2.5, mix, stir, stack and compact, and cover with plastic film or canvas, that is, cover the material with plastic film or canvas. It can be compacted with bricks, let stand for 24-36 hours, spread out, dry to remove water, make the water content 8-10%, crush it into powder, make the particle size 1-2mm, and obtain the mixture; The mixture is sprayed and granulated by a granulator to obtain a finished product.

Embodiment 2

[0015] Embodiment 2: get the plant ash 220Kg of furfural slag 300Kg, biological power plant, air-dry, make its moisture content be 20%, with above-mentioned material mixing, stir, stack and compact, cover with plastic film or canvas, promptly use plastic film or After the canvas covers the material stack, compact it with bricks around it, let it stand for 30 hours, spread it out, dry it in the sun to remove the moisture, make it 10% moisture, and crush it into powder, so that the particle size is 1-2mm , to obtain a mixture; the mixture is sprayed and granulated with a granulator to obtain a finished product.

Embodiment 3

[0016] Embodiment 3: get the plant ash 250Kg of furfural slag 300Kg, biological power plant, air-dry, make its moisture content be 18%, with above-mentioned material mixing, stir, stack and compact, cover with plastic film or canvas, promptly use plastic film or After the canvas covers the material stack, it can be compacted with bricks around it, let it stand for 32 hours, spread it out, dry it in the sun to remove the moisture, make it 10% moisture, and crush it into powder to make the particle size 1-2mm , to obtain a mixture; the mixture is sprayed and granulated with a granulator to obtain a finished product.

[0017] In a word, the method of the present invention can turn waste into treasure, and is simple and easy to implement. The organic fertilizer produced by plant ash and furfural slag from biological power plants can adjust soil structure, improve soil physical and chemical properties, promote crop growth and increase yield, and can be popularized and used.

Abstract

The invention provides a method for producing organic fertilizer by plant ash of biological power plants and furfural dregs. The method includes the following steps: collecting the furfural dregs and the plant ash of the biological power plants and drying the same until the water content thereof ranges from 15% to 20%; mixing and stirring the furfural dregs and the plant ash of the biological power plants according to the weight ratio of 2.7 to 3:2.2 to 2.5, stacking and compacting, and sealing the same with a plastic film or canvas, stewing the same for 24 to 36 hours before spreading and drying for removing water until the water content of the furfural dregs and the plant ash ranges from 8% to 10%, smashing the same into powder with particle size ranging from 1mm to 2mm, so that a mixture is formed; then granulating the mixture by a granulator in a guniting manner, and finally the organic fertilizer is produced. By the method which is simple and easy to realize, waste can be changed into treasure, the soil structure can be adjusted by the organic fertilizer produced by the plant ash of the biological power plants and the furfural dregs, physical and chemical characteristics of the soil can be improved and growth of crops can be accelerated and yield thereof can be increased.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and recycling of industrial waste, and relates to a method for producing organic fertilizer by using plant ash and furfural slag from a biological power plant. Background technique [0002] Furfural slag and donkey-hide gelatin slag are industrial waste residues after the production of furfural and donkey-hide gelatin. At present, they are discarded as industrial waste and pollute the environment. Furfural slag contains 24%-30% of fulvic acid, 0.04% of available nitrogen, 0.56% of available phosphorus, and a pH value of 1.90 Left and right, because furfural slag is acidic, it is directly used as fertilizer in the field, and crops cannot absorb it, and the effect of increasing production cannot be achieved. [0003] Plant ash in biological power plants is the ash and soot in the flue gas produced by the power plant after the use of agricultural crops to generate electricity. It con...
