Problems solved by technology

[0003] Fluid organic wastes such as cassava dregs, maling potato dregs, sugar factory filter mud, yeast waste liquid, etc., have a very large amount of discharge. Because they are in a fluid state, it is difficult to treat them, and the cost of corporate governance is extremely high. If they are not treated, they will cause great environmental pollution.
At present, in order to solve the problem of environmental protection emissions, some enterprises have added evaporation and drying devices, used a large amount of coal and gas as heat sources to provide steam to concentrate and dry the waste liquid, and developed market uses at a price lower than cost to try to digest them, resulting in Great waste of resources and re-pollution of the environment
Or use the method of occupying a large amount of cultivated land to dry them naturally to reduce moisture and use them after curing. However, the treatment cycle is long and the treatment efficiency is extremely low, which is far from meeting the discharge requirements.

Embodiment 1

[0033] This embodiment is an example of producing powdered bio-fertilizer.

[0034] A method of utilizing waste organic matter to produce biological fertilizers, comprising the steps of:

[0035] Grind the various dried straws purchased back to below 18 meshes for later use, put 500 kg of crushed straw powder into the blender, and mix according to straw powder: cassava slag or sugar factory filter mud or yeast waste liquid = Use a measuring scale (pump) with a ratio of 1:1 to mix cassava residue with a water content of about 50-60% or sugar factory filter mud or yeast waste liquid into the mixer, and add 2-4 kg of straw decomposing agent and 3-5 kg ​​of urea. Control the water content of the stirrer to 20% to 30%, stir it evenly, and send it to the fermentation tank for stacking and fermentation for 15 days. During the fermentation process, turn the pile twice according to the temperature situation. After the fermentation is complete, the fermented organic matter will be obtai...

Embodiment 2

[0039] This embodiment is an example of producing powdered bio-fertilizer.

[0040] The steps of the method for processing the mixed fermentation of straw powder and waste residue liquid are the same as those in Example 1.

[0041] Production of 1000 kg of powdered bio-fertilizer:

[0042] Take 500 kg of fermented organic matter, 50 kg of urea, 100 kg of ammonium sulfate, 70 kg of powdered monoammonium phosphate, 30 kg of potassium sulfate, 50 kg of bentonite, 75 kg of calcium stone powder, 75 kg of soil inoculant, 30 kg of silicon fertilizer, Mix 20 kg of trace element fertilizer into a blender to stir evenly, measure and pack to obtain the powdery bio-fertilizer. Its effective components are organic matter ≥ 20%, nitrogen + phosphorus + potassium ≥ 13%, the number of beneficial microorganisms ≥ 30 million per gram of fertilizer, and trace elements such as active silicon, calcium, magnesium and zinc account for more than 20%.

Embodiment 3

[0044] This embodiment is an example of producing granular bio-fertilizer.

[0045] The steps of the method for processing the mixed fermentation of straw powder and waste residue liquid are the same as those in Example 1.

[0046] Production of 1000 kg of granular bio-fertilizer:

[0047]Take 350 kg of fermented organic matter, 50 kg of soil inoculant, 75 kg of silicon fertilizer, 25 kg of micro-fertilizer, 150 kg of urea, 75 kg of calcium magnesium phosphate fertilizer, 175 kg of ammonium chloride, 50 kg of powdered monoammonium phosphate, and Potassium 50 kg, mixed into the mixer and stirred evenly, the evenly stirred material was sent to the extrusion granulator for granulation through the conveyor belt, and the granular bio-fertilizer was obtained by measuring and packaging. Its effective components are organic matter ≥ 15%, nitrogen + phosphorus + potassium ≥ 20%, the number of beneficial microorganisms ≥ 0.2 billion per gram of fertilizer, soluble silicon, calcium, mag...

Abstract

The invention discloses a method for producing a bio-fertilizer from waste organic matters. The method comprises the following steps of: treating liquid and semi-liquid industrial wastes into solid organic matters according to the liquid adsorption property of dry straw; inoculating strains into the treated solid organic matters for fermenting; and adding a biological agent and nitrogen-phosphorus-potassium nutrients into the fermented organic matters for mixing or pelletizing to obtain the bio-fertilizer. The invention has the characteristics of simple method, realization of recycling of resources, promotion of the development of environmentally-friendly and ecological organic agriculture and guarantee of the safety of agricultural products and makes wastes profitable.

Description

1. Technical field [0001] The invention relates to an agricultural fertilizer and a preparation method, in particular to a method for producing biological fertilizer by using waste organic matter. 2. Background technology [0002] The amount of crop stalks is large, and after they are harvested and placed in the field to dry, most of them are directly burned in the field, causing serious air pollution, and in some places even leading to major accidents and huge economic losses. A large amount of agricultural straw has basically not been developed and utilized. [0003] Fluid organic wastes such as cassava dregs, maling potato dregs, sugar factory filter mud, yeast waste liquid, etc., have a very large amount of discharge. Because they are in a fluid state, it is difficult to treat them, and the cost of corporate governance is extremely high. If they are not treated, they will cause great environmental pollution. . At present, in order to solve the problem of environmental ...
