Description
Technical field
The invention belongs to environmental protection and technical field of fertilizers, and in particular to a kind of to produce water solubility using the waste water of bean product
The production method of humic acid fertilizer.
Background technology
With progress of the epoch, in order to ensure national health, requirement of the country to food hygiene and food security
Increasingly tighter, the bean product operator of some manually operated individual workship's forms is eliminated, instead can protect
It is up to standard to hinder sanitary condition, ensures the modern industrial process enterprise of food security.Bean product industry industrialized production will generate greatly
The discharge of wastewater of amount, it is the important pollution sources of environment again.But soybean peptide, vegetable protein, middle trace element contained in waste water
And some stealthy substances needed for crop, be the rare organic nutrition synthetic of crop, be discharged be to resource one
Kind waste.
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 have the function of phosphorus decomposing, potassium decomposing, fixed nitrogen, while also there is various medicament residues, the hormone eliminated in fruit
The effect of residual and chemical residual.
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 mineral humic acid, organic matter, a variety of middle trace elements
And the Organic nutrient needed for crop, it is both the organic nutrient aganic nutrient agent of crop and the high-quality modifying agent of soil.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 is difficult to be absorbed and used by plants, and does not have the effect of organic fertilizer, causes the waste of resource.
Invention content
It is an object of the invention to provide a kind of using the waste water of bean product and mineral humic acid as raw material, produces fulvo acid
The production method of fertilizer.
For this purpose, the present invention provides the producers that water-soluble humic acid fertilizer is produced with the waste water of bean product in a kind of utilization
Method includes the following steps：
Step 1：Bean Products Factory's waste water is added in reaction kettle and is heated to 80 DEG C~90 DEG C, reinforces alkali, it is useless according to bean product
Water and mineral humic acid 100mL：The ratio of 1.0-1.3g is added, and adjusts pH value and reaches 9, heating mixed liquor to boiling；
Step 2：By mineral humic acid according to mineral humic acid：Mixed liquor=1g：The ratio of 3~3.5mL is added to boiling
Mixed liquor in, continue heating stirring；
Step 3：Control reaction kettle temperature be 90 DEG C~95 DEG C, keep 3 hours, be cooled to 85 DEG C, then keep 2 hours i.e.
It can.
The reaction kettle is to heat open automatic stirring reaction kettle.
The effective content of the mineral humic acid is >=45%.
The mesh of the grain size of the mineral humic acid >=120.
The mineral humic acid：The ratio of mixed liquor is 1g：3.5mL.
In the step 3, the temperature for controlling reaction kettle is 95 DEG C, is kept for 3 hours, is then cooled to 85 DEG C, then keep 2
Hour.
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 present invention organically combines the two using soybean wastewater and mineral humic acid as raw material,
So that resources circulation is recycled, produced and be easily absorbed by crops utilization, can effectively improve soil, improves crop growth environment, carry
The fulvo acid of high crop quality；A new approach is opened for Bean Products Factory's contaminated wastewater improvement, and makes resource
Recycling has reached environmental protection, the target of pollution administration；Solve mineral humic acid cannot effectively improve soil and by
The defect that crop is absorbed and utilized can effectively reduce the dosage of chemical fertilizer, pesticide, reduce the wasting of resources.
