Description
Technical field
It is more particularly to a kind of multiple with reference to physics, chemistry, microorganism the invention belongs to weathered coal humic acid activating technology field
The method for closing activation weathered coal humic acid.
Background technology
Weathering coal reserves in China's is very abundant, estimates nearly hundred billion tons, is mainly distributed on Xinjiang, the Inner Mongol, Guizhou, Shanxi etc.
The more area of open coal mine distribution, is not utilized effectively so far.Weathered coal is a kind of mineral containing substantial amounts of humic acid,
Humic acid total content is generally between 30~70%, and up to more than 80%.Humic acid is a kind of natural polymer, is contained
The group such as the elements such as carbon, hydrogen, oxygen, nitrogen and aromatic proton, phenolic hydroxyl group, carboxyl, methoxyl group, has faintly acid, hydrophily, ion exchange
Property, the performance such as oxidation-reduction quality and physiological activity, not only have in the field such as metallurgical, chemical industry and environmental protection it is very extensive should
With, and can be used in agricultural production as important fertilizer and growth regulator.Some is used for conditioned soil loamy texture at present
Ground, improves soil porosity, reduces the content of the mineral element such as pH value, increase organic matter, humic acid content and calcium, magnesium, into
One step is increase soil fertility.But due to weathered coal stable structure, exist more in the form of calcium, magnesium insoluble matter, it is this without
Activation process is directly added into weathered coal, and general water-soluble and physiological activity is very low, is not easy to be absorbed by plants, direct using effect is very
Difference.
Weathered coal activation method mainly has Mechanical Crushing（Physics）, aqueous alkali extraction activation method（Chemistry）, biosolubilization
Method（Biology）Deng.The method that related weathered coal activation domestic at present is mainly activated using alkalization, the humic acid in weathered coal is more
First organic acid can react the soluble humate of generation with alkali, referring to CN1400197A, CN101429072A；But also there is report
Road microbial degradation production fulvic acid method, material and raw coal are mixed, by people's degradation bacteria strains, fermentation activation is carried out to coal, is joined
See CN1236065C, CN1510142A.Every kind of activation method respectively has advantage and disadvantage, and physically activated operating procedure is simple, activation speed
Degree is fast, but extraction conditions are single, energy consumption, and activation degree is low；The speed of chemical activation is fast, efficient, but experiment condition is complicated, needs
Certain temperature and time are wanted, energy consumption, consumables cost are high；The active mass of microorganism is good, but time-consuming, cumbersome, speed is slow, effect
Rate is low.
The content of the invention
To overcome drawbacks described above, the technical problem to be solved in the present invention is to provide a kind of combination physics, chemistry, microorganism
The method of multiplicity reactivation weathered coal humic acid, with the content of free humic acid in weathered coal humic acid after raising activation.

Phytic acid content improves 6~10%；
Step 3：Weathered coal bio activates；On the basis of step 2, microbial fermentation is carried out using the method for microbe inoculation
Activate, the weathered coal after chemical activation of learning from else's experience, is separately added into the rice bran for accounting for weathered coal weight 1~5%, sucrose is uniformly mixed；Add
Account for the liquid composite bacteria agent of weathered coal weight 0.1~1% and account for the water of weathered coal weight 20~30%, the temperature of water is 30 DEG C, is stirred
Mix mixing；It is placed in 30~50 DEG C of isoperibols and ferments, suitable quantity of water is supplemented according to fermentation appearance, rice bran, sucrose is kept 30
~50% humidity yeasting, ferments 10~15 days；Free humic acid content improves 6~10% in gained weathered coal.
Further, the particle diameter of the weathered coal is 60~100 mesh.
Further, the dosage of the ammonium bicarbonate activated solution is the 20% of weathered coal weight.
Further, the activation of microorganism liquid mix bacterium agent be bacterium, fungi, one or both of actinomyces with
On combination, dosage be weathered coal weight 0.4%.
Further, the rice bran, the dosage of sucrose are respectively the 5% of weathered coal weight.
Further, the weathered coal progress activation of microorganism ferments 12 days in 40 DEG C of isoperibols.
The present invention be researcher real work pilot scale make it is a kind of using composite algorithm to the humic acid in weathered coal
The method activated, this method combine physics, chemistry, the activation advantage of microorganism, are added on the basis of conventional method
Activator and fermentation materials, make the humic acid activation effect in weathered coal more preferable.By the wind of composite bioactive treatment of the present invention
Change coal humic acid, free humic acid content improves 15~25%.
