Problems solved by technology

At present, in order to solve environmental problems, some enterprises have added evaporation and drying devices, using a large amount of coal and gas as heat sources to provide steam to concentrate and dry the waste liquid, and develop market applications at a price that is seriously lower than the cost in order to digest the waste liquid. Cause a great waste of resources and re-pollution of the environment
[0003] There is a large amount of crop straw, which is basically not developed and utilized, and most of them are directly burned in the field, causing serious air pollution, and in some places even causing major accidents, causing huge losses to the country and the people's economy
[0004] A large amount of fly ash produced by thermal power plants requires a large amount of farmland to be stacked. At present, only part of it has been developed for construction supplies, and there is still a large amount of fly ash that cannot be digested.
[0005] If the above three substances are not used rationally, they will cause serious impact on the environment.
The treatment methods currently used are all palliatives, not the root cause, waste of energy or repeated pollution, which do not meet the requirements of energy recycling

preparation example Construction

[0032] The method for preparing magnetic biological fertilizer of the present invention, comprises the steps:

[0033] 1. Grind the recovered and dried straws to below 18 mesh for later use, mix 500 kg of crushed straw powder into a mixer, and use a metering pump at the ratio of straw powder: yeast waste liquid = 1:1 during the mixing process Pump the yeast waste liquid with a water content of about 50-60% in the waste liquid storage tank into the mixer, and add 2-4 kg of straw decomposing agent and 3-5 kg ​​of urea, control the water content of the agitator to 20-30%, and stir After uniformity, it is sent to the fermenter for stacking and fermenting for about 15 days. During the fermentation process, the stack is turned twice according to the temperature. Pack into bags after fermentation is complete;

[0034] 2. Crush the returned thermal power plant fly ash to less than 60 mesh, send it to a magnetizer and magnetize it under a magnetic field of about 5000 gauss for 5 secon...

Embodiment 1

[0036] Present embodiment is the example of producing 1000 kilograms of powdery biological fertilizers:

[0037] Take 500 kg of straw yeast mixture fermented in step 1, 400 kg of magnetized fly ash in step 2, and 100 kg of soil inoculant, mix them into a mixer and stir evenly, measure and pack to obtain the powdery magnetic biological fertilizer. Its effective components are organic matter ≥ 25%, nitrogen + phosphorus + potassium ≥ 2%, the number of beneficial microorganisms ≥ 50 million per gram of fertilizer, and trace elements such as silicon, calcium, magnesium, iron, manganese, copper, zinc, molybdenum, etc. More than 15%, the magnetic component is 2.5%.

Embodiment 2

[0039] Present embodiment is the example of producing 1000 kilograms of powdery biological fertilizers:

[0040] Take 450 kg of straw yeast mixture fermented in step 1, 325 kg of fly ash magnetized in step 2, 75 kg of soil inoculant, 80 kg of urea, 50 kg of powdered monoammonium phosphate, and 20 kg of potassium chloride and mix them into a mixer Uniform, measured and packaged to obtain the powdery magnetic bio-fertilizer. Its effective components are organic matter ≥ 20%, nitrogen + phosphorus + potassium ≥ 10%, the number of beneficial microorganisms ≥ 35 million per gram fertilizer, soluble silicon, calcium, magnesium, iron, manganese, copper, zinc, molybdenum and other medium and trace elements It accounts for more than 10%, and the magnetic component is 2%.

Abstract

The invention relates to a magnetic biofertilizer and a preparation method. The preparation method comprises the following steps of: inoculating strains into straw powder and waste yeast liquid mixed according to certain proportion for fermentation, batching fermented organic matters into magnetized powdery coal ash, a biological bactericide and nitrogen-phosphate-potash nutrients, and blending or pelletizing to prepare the magnetic biofertilizer. The preparation method provided by the invention has the characteristics of being simple, changing waste into valuables, recycling resources, promoting green ecologic and organic agriculture development and guaranteeing the safety of agricultural products.

Description

1. Technical field [0001] The invention relates to an agricultural fertilizer and a preparation method, in particular to a magnetic biological fertilizer and a preparation method. 2. Background technology [0002] Yeast liquid is the waste liquid produced after the production of yeast. The amount is very large. A 10,000-ton yeast factory needs to discharge 30,000 tons of waste liquid a year. In some areas, the annual discharge of several 10,000-ton yeast factories Up to more than 100,000 tons, if discharged into the river, it will cause serious pollution. At present, in order to solve environmental protection problems, some enterprises have added evaporation and drying devices, using a large amount of coal and gas as heat sources to provide steam to concentrate and dry the waste liquid, and develop market applications at a price that is seriously lower than the cost in order to digest the waste liquid. Cause a great waste of resources and re-pollution of the environment. ...
