Embodiment 1

[0054] A preparation method of a desert transformation agent, specifically, comprises the following steps:

[0055] (1) drying and ball milling the phosphogypsum to obtain a phosphogypsum powder with a particle size of 50um;

[0056] (2) adding quicklime liquid to the phosphogypsum powder, stirring and neutralizing to obtain substance A containing leaching solution, and the pH value of the leaching solution is 6-7;

[0057] (3) Transfer the substance A containing the leaching liquid into the reaction container, mix and react the components in the reaction container, add an appropriate amount of water for washing, the weight ratio of water to substance A is 3:1, and then use the method of countercurrent rinsing Perform impurity removal treatment by means of removing soluble salts and heavy metal ions, then separate solid from liquid, and dry the solid to obtain phosphogypsum powder, wherein the moisture content of phosphogypsum powder is equal to 20%;

[0058] (4) drying and p...

Embodiment 2

[0061] A kind of preparation method of desert transformation agent, its difference with embodiment 1 is:

[0062] The particle diameter of the phosphogypsum powder obtained in step (1) is 30um;

[0063] In step (3), the weight ratio of water to substance A is 4:1, and the moisture content of the phosphogypsum powder is 10%;

[0064] In step (4), the edible fungus culture medium and Chinese medicine preparation residues mixed with microbial agents are selected for fermentation, sterilization, and disinfection to obtain fillers; specifically, the edible fungus culture medium and Chinese medicine preparation residues are dried and pulverized, and after drying, The water content of the edible fungus culture medium and the residue mixture of traditional Chinese medicine preparations is 10%, and the particle size is 1.0 mm.

[0065] Other processes are the same as in Example 1.

Embodiment 3

[0067] A kind of preparation method of desert transformation agent, its difference with embodiment 1 is:

[0068] The particle diameter of the phosphogypsum powder obtained in step (1) is 10um;

[0069] In step (3), the weight ratio of water to substance A is 3.5:1, and the moisture content of the phosphogypsum powder is 5%;

[0070] In step (4), the edible fungus culture medium mixed with microbial agents, residues of traditional Chinese medicine preparations, and poultry and livestock manure are selected for fermentation, sterilization, and disinfection to obtain fillers; specifically, the culture medium for edible fungi, residues of traditional Chinese medicine preparations, poultry The livestock manure is dried and pulverized, and the dried edible fungus culture medium, residues of traditional Chinese medicine preparations, and the mixture of poultry and livestock manure have a water content of 10% and a particle size of 0.5mm.

[0071] Other processes are the same as in ...

Abstract

The invention relates to the technical field of desert reconstruction, and discloses a preparation method of a desert reconstruction agent. The method comprises the following steps: drying and grinding ardealite to obtain ardealite powder; adding alkali liquor, stirring and neutralizing to obtain a substance A containing a leaching solution with the pH value of 6-7; transferring the substance A into a reaction container, adding a proper amount of water, removing impurities, and drying to obtain ardealite powder; selecting one or more of an edible mushroom culture medium doped with a microbial agent, traditional Chinese medicine preparation residues and livestock manure, and performing fermentation, sterilization and disinfection to obtain a filler; and mixing the ardealite powder with the filler, and packaging to obtain the reconstruction agent. The invention also discloses an application and a preparation device thereof. The reconstruction agent disclosed by the invention contains rich organic matters and cellulose, can effectively improve a granular structure formed by gelling with sand grains, increases the moisture storage capacity of the modified soil, and realizes the change of sand into soil. The modified ardealite is an air hardening cementing material, and the desert reconstruction effect has good continuity and stability.

Description

technical field [0001] The invention relates to the technical field of desert transformation, in particular to a preparation method, application and preparation device of a desert transformation agent. Background technique [0002] One-third of the earth's land is desert, and 43% of the land is facing the threat of desertification. China is one of the countries with the most severe desertification in the world, with a desertified land area of ​​2.64 million km 2 , accounting for 27.5% of the country's land area, among which the desert is the most serious hazard, and its area has reached 809,000 km 2 , and is still expanding, with an average of 610km per year 2 The left and right deserts are activated, of which 310km 2 The land was reduced to sand. [0003] From the physical characteristics of the desert, it can be known that the sand in the desert is mainly silica particles, there is no binding force between the particles, and there is no intermediary material hinge, and...
