Problems solved by technology

[0003] At present, the preparation of fertilizers from molasses alcohol waste liquid is mainly by fermenting molasses alcohol waste liquid, and then mixing them evenly with large, medium and trace element fertilizer raw materials and auxiliary materials, and then spraying, drying and granulating to obtain granular fertilizers. The resulting granular fertilizer is difficult to apply through modern fertigation systems
[0004] Microbial agents are commonly used additives for fertilizers, but direct application of microbial agents often results in limited growth and reproduction of microorganisms due to the lack of microbial nutrients, and the effect is not good

Embodiment 1

[0024] A method for producing water-soluble microbial fertilizer using molasses alcohol waste liquid, including the following steps:

[0025] Step 1: Put the molasses alcohol waste liquid into a pulse tank, and perform pulse sedimentation treatment on the molasses alcohol waste liquid with a pulse cycle of 45 seconds / time, and the treatment time is 3 hours to obtain the supernatant.

[0026] Step 2. Put the supernatant obtained in step 1 into a multi-effect evaporator, use the temperature of the supernatant itself to evaporate and remove water, and obtain a hammer degree of 60 0 Bx's molasses alcohol waste liquid concentrate.

[0027] Step three, set the hammer to 60 0 Transfer the Bx molasses alcohol waste liquid concentrate to the blending tank, and add 1% sodium hydroxide with a mass fraction of 60%. 0 The pH value of Bx's molasses alcohol waste liquid concentrate is adjusted to 5.5, and then transferred to the atomization plate on the top of the spray drying tower by a screw pump,...

Embodiment 2

[0030] A method for producing water-soluble microbial fertilizer using molasses alcohol waste liquid, including the following steps:

[0031] Step 1: Put the molasses alcohol waste liquid in the pulse drop tank with a pulse period of about 45 seconds / time and the pulse settling time for 3 hours to obtain the supernatant.

[0032] Step 2. Put the supernatant obtained in step 1 into a multi-effect evaporator, use the temperature of the supernatant itself to evaporate and remove water, and obtain a hammer degree of 62 0 Bx's molasses alcohol waste liquid concentrate.

[0033] Step three, set the hammer to 62 0 Transfer the Bx molasses alcohol waste liquid concentrate to the blending tank, and add 1.1% sodium hydroxide to reduce the weight to 62 0 The pH value of Bx's molasses alcohol waste liquid concentrate is adjusted to 5.5, and then transferred to the atomization plate on the top of the spray drying tower by a screw pump, and sprayed at a high temperature under the conditions of an i...

Embodiment 3

[0036] A method for producing water-soluble microbial fertilizer using molasses alcohol waste liquid, including the following steps:

[0037] Step 1: Put the molasses alcohol waste liquid in the pulse drop tank with a pulse period of about 45 seconds / time and the pulse settling time for 3 hours to obtain the supernatant.

[0038] Step 2. Put the supernatant obtained in step 1 into a multi-effect evaporator, use the temperature of the supernatant itself to evaporate and remove water, and get a hammer of 65 0 Bx's molasses alcohol waste liquid concentrate.

[0039] Step three, set the hammer to 65 0 Transfer the Bx molasses alcohol waste liquid concentrate to the blending tank, and add 4% ammonium dihydrogen phosphate and 1.2% sodium hydroxide by mass fraction to change the hammer to 65 0 The pH value of Bx's molasses alcohol waste liquid concentrate is adjusted to 5.6, and then transferred to the atomization plate on the top of the spray drying tower by a screw pump, and high-temperatu...

Abstract

The invention discloses a method for producing a water-soluble microorganism fertilizer from a molasses alcohol waste liquid. The method comprises the following steps: firstly, preparing a concentrated molasses alcohol waste liquid of which the brix degree is 40-800Bx; further mixing and drying the concentrated molasses alcohol waste liquid and a microbial agent to obtain dry powder of which the water content is within 10%, so as to obtain the water-soluble microorganism fertilizer. The method is simple and practical in process, and rich nutrition elements in the alcohol waste liquid are sufficiently utilized to prepare a water-soluble microorganism fertilizer product. The water-soluble microorganism fertilizer disclosed by the invention is good in dissolubility, the working intensity canbe alleviated through application of modern agriculture trickle irrigation and sprinkling equipment, both the problem of environment pollution caused by alcohol waste liquids is solved and wastes liquids can be turned into wealth, and resource utilization can be achieved.

Description

Technical field [0001] The invention belongs to the technical field of microbial fertilizer preparation, and in particular relates to a method for producing water-soluble microbial fertilizer using molasses alcohol waste liquid. Background technique [0002] Molasses alcohol waste liquid is a kind of high-concentration organic waste liquid, which contains a large amount of carbohydrates, fat, protein, cellulose and other organic matter. 70% of the solids in the molasses alcohol waste liquid are organic matter, including sugar, protein, amino acids, vitamins, etc.; the remaining 30% is ash, containing nitrogen, phosphorus, potassium, calcium, magnesium and other inorganic salts, with high potassium content and heavy metal traces The amount is non-toxic and harmless. In the process of molasses fermentation to produce alcohol, a high concentration of molasses alcohol waste liquid will be produced, and about 10-15 tons of molasses alcohol waste liquid will be produced for every 1 to...
