Embodiment 1

[0039] A garden soil ecological restoration agent, the preparation method is as follows:

[0040] Step 1, after cleaning the vermiculite particles, grinding them into powder, passing through a 400-mesh sieve to obtain vermiculite powder; dissolving boron trioxide in 2.1 mol / L hydrochloric acid, the mass ratio of boron trioxide and hydrochloric acid is: 1:12, obtain diboron trioxide solution; Dissolve scandium trichloride in deionized water, the mass ratio of scandium trichloride to deionized water is 1.14:10, obtain scandium trichloride solution;

[0041] Step 2, mix the scandium trichloride solution with the diboron trioxide solution, wherein the mass ratio of the diboron trioxide and the scandium trichloride solution is 1:14, and then add 15% of the mass of the scandium trichloride solution. Polyvinyl alcohol, heat up to 60°C, stir and mix evenly, add vermiculite powder and mix evenly, then dry under reduced pressure, and after complete drying, a solid mixture is obtained; ...

Embodiment 2

[0048] A garden soil ecological restoration agent, the SEM image is as follows figure 1 As shown, the preparation method is as follows:

[0049] Step 1, after cleaning the vermiculite particles, grinding them into powder, passing through a 300-mesh sieve to obtain vermiculite powder; dissolving boron trioxide in 1.8 mol / L hydrochloric acid, the mass ratio of boron trioxide and hydrochloric acid is: 1:10 to obtain diboron trioxide solution; dissolve scandium trichloride in deionized water, and the mass ratio of scandium trichloride to deionized water is 0.89:10 to obtain scandium trichloride solution;

[0050] In step 2, the scandium trichloride solution is mixed with the diboron trioxide solution, wherein the mass ratio of the diboron trioxide to the scandium trichloride solution is 1:12, and 12% of the mass of the scandium trichloride solution is added. polyvinyl alcohol, heat up to 55°C, stir and mix evenly, add vermiculite powder and mix evenly, then dry under reduced pres...

Abstract

The invention discloses a garden soil ecological restoration agent preparation method, which comprises: 1, washing vermiculite particles, grinding into powder, and screening; 2, dissolving diboron trioxide in an acid solution, and mixing with a scandium trichloride solution under the condition of an adhesive; 3, the solid mixture is placed in a tubular furnace to be subjected to high-temperature roasting treatment, and scandium diboride / expanded vermiculite is obtained; step 4, treating scandium diboride / expanded vermiculite by using dicarboxylic acid; step 5, carrying out acylating chlorination on the carboxylated scandium diboride / expanded vermiculite; 6, trimethoprem reacts with scandium diboride acylating chloride / expanded vermiculite, and the garden soil ecological restoration agent is obtained. The ecological restoration agent has a good restoration effect on soil, and inorganic pollutants and organic pollutants in the soil can be restored at the same time.

Description

technical field [0001] The invention relates to the field of soil restoration, in particular to a garden soil ecological restoration agent and a preparation method. Background technique [0002] Soil is a loose surface layer on the surface of the continent that provides fertility for plant growth. With the development of modern industry and agriculture, various industrial waste water, harmful gases and other pollutants enter the soil, and the accumulation of harmful substances in the soil is also increasing. Agricultural production activities on contaminated soil will inevitably lead to food safety problems, and living and living on it will directly endanger human health. In addition, some harmful costs are also involved in various forms of solid, liquid, and gas. Nature and ecosystem cycles, causing damage to humans and the natural world on a wider scale. [0003] The common pollution forms of garden soil include inorganic pollutants and organic pollutants. Among them, the...
