Description
Technical field
The present invention relates to the preparing technical field of biomass carbon, more particularly to a kind of modified soil of addition monosodium glutamate waste liquid
Modifying agent straw biomass charcoal and preparation method thereof.
Background technology
Agricultural crop straw is a kind of valuable renewable resource, but for a long time due to by consumption idea, life style and
The influence of the factors such as agricultural production time, agricultural straw resource is completely in consumption high, high pollution, the situation of low output, phase
When many a part of agricultural crop straws go out of use or burn, rational exploitation and utilization is not obtained, both caused the serious wave of resource
Take, serious environmental pollution is caused again, serious harm is caused to human health and safety, it has also become a great society problem.For
This, national departments concerned has done substantial amounts of work, and takes taboo to burn stalk control measures, but cures the symptoms, not the disease, thus to existing
Agricultural crop straw comprehensive utilization treatment enjoys the concern of domestic and international expert.The such as straw power generation, natural pond taken both at home and abroad at present
There is application limitation and be difficult to promote on a large scale in various processing methods such as gas fermentation, compost and measure.Biomass carbon is that have
A kind of rich carbon slightly solubility solid matter that machine material is produced in anoxic or anaerobic environment through high temperature pyrolysis.Its quite stable, it is difficult
With degraded and compared with other any type of organic matters, biomass carbon has the function of superpower withholding nutrient.Therefore make it
A kind of utilization for soil conditioner and carbon sequestration material in farmland soil is possibly realized.
Data has shown that since the 50's of 20th century, China's applying quantity of chemical fertilizer occupies the 1st, the world according to statistics.Chemical fertilizer
Grain yield largely is significantly increased, on the other hand also results in a large amount of P, N, K elements not utilized and is enriched with soil.
However, because the global cycle period of P element is more much longer than other elements (N, K), thus in most of ecosystems,
P element becomes the restricted element of growth of microorganism, is also the main cause for causing body eutrophication and soil depletion.
And have that specific surface area is generally less than normal as soil conditioner by the use of biomass carbon, the relatively weak deficiency of adsorption capacity, therefore inhale
Phosphorus efficiency is low to be unfavorable for agricultural production, therefore, document《The preparation technology and its suction phosphorus of calcium chloride activation rice straw biomass carbon
Performance study》With rice straw as raw material, the calcium chloride of mass fraction 10% prepares active bio matter charcoal for activator, used as control
The suction P materials of widespread pollution from the overuse of fertilizers and pesticides in rural area processed.Result of the test shows：P clearances can reach 97%, and pH value of solution rises to 9.52 from 6.87.
But the method for modifying in document is more single, function is also single, obtained biomass carbon only in soil not
The phosphorus for utilizing has preferable adsorption effect, but, with the fast development of modern industrialization, a large amount of industrial wastewaters blindly enter agriculture
Field, and the chemical fertilizer of heavy dose is excessively used, and excessive heavy metal ion influence plant growth is largely enriched with soil, and also indirect
Influence human health, simultaneously because biomass carbon surface carries negative electrical charge, for the heavy metal adsorption existed with anionic form
Effect is poor, uses retain water and nutrients and other effects of taking root also poor as soil conditioner, so that being improved existing process.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of modified soil of addition monosodium glutamate waste liquid
Modifying agent straw biomass charcoal and preparation method thereof.
The present invention is achieved by the following technical solutions：
It is a kind of to add the modified soil conditioner straw biomass charcoal of monosodium glutamate waste liquid, it is made from the following raw materials in parts by weight：
Wheat stalk 80-82, dandelion 18-20, dry cow dung 5-8, calcium chloride 3-4, iron chloride 1.3-1.5, thiocarbamide 0.1-0.2, tea soap
Plain 1.3-1.6, monosodium glutamate waste liquid 8-10, poly-aspartate 2.1-2.4, the sodium hydroxide solution of sepiolite powder 11-13,10wt.%
In right amount, appropriate mix acid liquor, appropriate deionized water.
A kind of preparation method of the modified soil conditioner straw biomass charcoal of described addition monosodium glutamate waste liquid, including
Following steps：
（1）Calcium chloride, iron chloride are stirred and evenly mixed, is ground 20-30 minutes, it is 10% to add deionized water to be configured to mass fraction
Hybrid activator it is standby；
（2）Wheat stalk, dandelion drying are cut into 2 cms and be well mixed, the sodium hydroxide solution of 10wt.% is placed in
Immersion 48 hours, taking-up is washed with deionized to neutrality, with step（1）Hybrid activator according to impregnating ratio 1: 0.5 soak
24 hours, filtering, the 105-110 DEG C of drying in baking oven；
（3）By step（2）Material is put into tube furnace, under nitrogen protection with 20 DEG C of min- 1The rate of heat addition be warming up to 700-
720 DEG C, keeping temperature charing process 60 minutes is cooled to room temperature under nitrogen protection, adds mix acid liquor ultrasonic oscillation 8-
Supernatant is outwelled in centrifugation after 10 hours, is washed with deionized to neutrality, and drying is pulverized；
（4）By step（3）Material, sepiolite powder are mixed and add the stirring of monosodium glutamate waste liquid, poly-aspartate and other residual components
Mix, water spray granulation is crossed 2-4mm and sifts out material.
Described mix acid liquor is 1mol L- 1Volume ratio for 1: 1 hydrochloric acid-hydrofluoric acid solution.
It is an advantage of the invention that：The present invention is first by wheat stalk, dandelion sodium hydroxide solution immersion treatment removing
The wax of material surface, ash content and other be dissolved in the impurity of water, then after being soaked with the compound hybrid activator of calcium chloride, iron chloride
The means such as high temperature carbonization, pickling treatment, pickling dramatically increases specific surface area, pore volume and the pore-size distribution of biomass carbon, carries significantly
The adsorption capacity of biomass carbon high so that in the Ca of straw charcoal inner surface2+And Fe3+With reference to hydroxyl can quickly by soil
Unnecessary phosphate anion substitution, inhales phosphorus efficiency high, and be combined the straw biologicals obtained in composition such as sepiolite powder, monosodium glutamate waste liquid
Matter charcoal is used for retain water and nutrients effect is significant during soil conditioner, has both improve agricultural crop straw comprehensive utilization ratio, and agricultural production is improved again
Product yield and quality.
