Description
Technical field
The present invention relates to the production technology of humic acid, and in particular to the production technology of fulvo acid, belongs to fertilizer skill
Art field.
Background technology
Big-and-middle-sized pig plant is modernized, the method fermented using methane-generating pit is fermented to swine excrement, is formed methane, is done
Harmless treatment, air is purified.The process to form methane generates substantial amounts of biogas slurry (swine excrement biogas slurry), and biogas slurry includes a variety of
Organic nutrition composition needed for crop, organic liquid fertilizer can be done, but the effective content of the organic nutrition composition contained by it is too low,
Actual commodity value, friend peasant, large plantation family and planting base are not inconvenient to use, and cause the biogas slurry of pig plant
Largely steal row to leave about, this is not only the waste to efficient resource, also results in secondary environmental pollution.
Mineral humic acid has black, brown, yellow three kinds, because of the size of its network molecular structure and how much differences of molecular weight, table
Different dissolubilities is revealed：It is not soluble in water, be slightly soluble in water, be dissolved in water entirely.Wherein, the humic acid for being dissolved in water entirely claims water-soluble corruption
Phytic acid.Fulvo acid, which not only has, decomposes nitrate residual, medicament residue, hormone residues and various chemical residuals in soil
Effect, also there is phosphorus decomposing, potassium decomposing, fixed nitrogen, while also there is various medicament residues, the hormone eliminated in fruit
And the effect of chemical residual.
Mineral humic acid, such as：Weathered coal, lignite, it is the mineral matter after superficial oxidation, without any pollution, it and soil
Earth is close relative source, is the rare carbon of soil, includes the work such as substantial amounts of humic acid, organic matter, a variety of middle trace elements
Organic nutrient needed for thing, it is both the organic nutrient aganic nutrient agent of crop, is the high-quality modifying agent of soil again.But because it is slightly soluble in
Water, in addition it is not soluble in water, so the various chemical residuals in soil, medicament residue etc. can not be decomposed, do not reach improved soil
Effect, its nutrition is difficult to be absorbed and used by plants, and fertilizer efficiency is bad, causes the wasting of resources.
The content of the invention
It is an object of the invention to using swine excrement biogas slurry and mineral humic acid as raw material, the two is organically combined, produced
It is a kind of be easily absorbed and used by plants, can effective improved soil fulvo acid.
In order to realize above-mentioned target, the present invention adopts the following technical scheme that：
The production technology of fulvo acid, it is characterised in that using swine excrement biogas slurry and mineral humic acid as primary raw material
Produced, specifically include following steps：
Step1：By highly basic and swine excrement biogas slurry according to highly basic：Swine excrement biogas slurry 1g:100mL~120mL ratio adds
Into reactor, mixed liquor boiling is heated to, foregoing highly basic is sodium hydroxide or potassium hydroxide；
Step2：By mineral humic acid according to mineral humic acid：Mixed liquor=1g:2mL~4mL ratio is added to boiling
Mixed liquor in, heating stirring；
Step3：The temperature for controlling reactor is 90 DEG C~95 DEG C, keeps 3h~4h, is then cooled to 80 DEG C~85 DEG C, then
2h~3h is kept to produce.
The production technology of foregoing fulvo acid, it is characterised in that in Step1, foregoing sodium hydroxide and hydrogen-oxygen
Change the purity of potassium >=95%.
The production technology of foregoing fulvo acid, it is characterised in that in Step1, foregoing sodium hydroxide or hydrogen-oxygen

Put formula automatic stirring reactor.
The production technology of foregoing fulvo acid, it is characterised in that in Step2, foregoing mineral humic acid has
Imitate content >=45%.
The production technology of foregoing fulvo acid, it is characterised in that in Step2, the grain of foregoing mineral humic acid
The mesh of footpath >=120.
The production technology of foregoing fulvo acid, it is characterised in that in Step2, foregoing mineral humic acid is with mixing
Liquid is closed according to 1g:3mL ratio mixing.
The production technology of foregoing fulvo acid, it is characterised in that in Step3, the temperature for controlling reactor is
90 DEG C, 3h is kept, is then cooled to 80 DEG C, then keep 2h to produce.
The present invention is advantageous in that：Using swine excrement biogas slurry and mineral humic acid as raw material, the two is organically combined, it is raw
Output is easily absorbed and used by plants, can effective improved soil fulvo acid, not only prevented large-scale pig plant natural pond
Liquid disorderly row leaves about phenomenon, and solve the problems, such as mineral humic acid can not effectively improved soil be absorbed by crops utilization.
