Abstract
The present invention relates to a kind of production methods of fulvo acid, and potato is mainly produced starch wastewater and highly basic is proportionally added into reaction kettle, then mineral humic acid is added in the mixed liquor of boiling, control the temperature of reaction kettle, keep 2h ~ 3h；The waste water and mineral humic acid that this method produces starch using potato organically combine the two as raw material, have produced and have easily been absorbed and utilized by other crops such as potato, can effectively improve the fulvo acid of soil.The waste water that the potato made produces starch reaches zero emission standards, and also solves the problems, such as resources circulation recycling and reusing.Solve the problems, such as that mineral humic acid cannot effectively improve soil and be absorbed by crops utilization.
Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of production method of fulvo acid.
Background technique
Since reform and opening-up, national relevant strategies it is further wide in range, encourage peasant shake off poverty and set out on the road to prosperity as early as possible, but the north some
Area is limited by geographical climate environment, and especially areas, the potato such as northern Gansu, Inner Mongol, Ningxia, Yulin has become
The main producing region in China, peasant's volume income increase year after year, and cultivated area also expands year by year, and the deep processing of potato is also further speeded up.
The factory of large-scale potato deep processing comes into being, and the waste water after largely producing potato starch is unprocessed, and disorderly row leaves about, and provides to water
Source causes serious pollution.But in waste water containing various trace elements needed for Potato cultivars and stealthy substance also in vain by
It exhausts, this is a kind of waste to resource again.Mineral humic acid has black, brown, yellow three kinds, because its network molecular structure size and
How much differences of molecular weight show different dissolubilities: not soluble in water, be slightly soluble in water, be dissolved in water entirely.Wherein, it is dissolved in entirely
The humic acid of water claims fulvo acid.Fulvo acid, which not only has, to be decomposed nitrate residual in soil, medicament residue, swashs
The effect of element residual and various chemical residuals also has the function of phosphorus decomposing, potassium decomposing, fixed nitrogen, while also having and eliminating fruit
In various medicament residues, hormone and chemical residual effect.
Mineral humic acid, such as: weathered coal, lignite are the minerals after superficial oxidation, without any pollution, it and soil
Earth is close relative source, is the rare carbon of soil, includes a large amount of humic acid, organic matter, a variety of middle microelement lamps and makees
Organic nutrient needed for object is both the organic nutrient aganic nutrient agent of crop and the high-quality modifying agent of soil.But because it is slightly soluble in
Improvement soil is not achieved so various chemical residuals, the medicament residue etc. in soil cannot be decomposed in water or even not soluble in water
Effect, its nutrition are difficult to be absorbed and used by plants, and fertilizer efficiency is bad, causes the waste of resource.
Summary of the invention
It is an object of the invention to provide a kind of waste water for producing starch using potato and mineral humic acid as raw material, produces water solubility
The method of humic acid.
For this purpose, including the following steps: the present invention provides a kind of production method of fulvo acid
Step1: potato is produced starch wastewater and highly basic according to highly basic: the ratio that potato produces starch wastewater is 100mL
~120mL:1.0-1.3g is added in reaction kettle, its pH value is made to reach 9, is heated to mixed liquor boiling；
Step2: by mineral humic acid according to mineral humic acid: mixed liquor=1g~1.3g:3.5~4mL ratio is added
Into the mixed liquor of boiling, continue heating stirring；
Step3: the temperature for controlling reaction kettle is 90 DEG C~95 DEG C, keeps 2h~3h, is then cooled to 80 DEG C~85 DEG C, then
Keep 3h.
The highly basic: potato is produced the ratio that the ratio of starch wastewater is 100mL:1.0-1.3g and is mixed, its pH value is reached
To 9.
The reaction kettle is to heat open automatic stirring reaction kettle.
The effective content of the mineral humic acid is >=45%.
The partial size of the mineral humic acid >=120 mesh.
The mineral humic acid: the ratio of mixed liquor is 1g:3.5mL.
In the step3, the temperature for controlling reaction kettle is 90 DEG C, keeps 2h, is then cooled to 80 DEG C, then keep 3h i.e.
It can.
The highly basic is sodium hydroxide or potassium hydroxide.
The purity of the sodium hydroxide or potassium hydroxide is >=95%.
Beneficial effects of the present invention: the waste water and mineral humic acid that the present invention produces starch using potato is raw materials, by the two
It organically combines, has produced and be easily absorbed and utilized by other crops such as potato, can effectively improve the fulvo acid of soil, together
When, the potato made produces the wastewater zero discharge of starch, reduce the pressure of depollution of environment waste water, so that environmental quality is improved,
With good environment protecting, and also solve the problems, such as resources circulation recycling and reusing, solving mineral humic acid cannot have
Effect improvement soil and the problem of being absorbed by crops utilization.
