Embodiment 1

[0038]The granules for treating and repairing soil inorganic matter pollution according to Embodiment 1 of the present invention are mainly composed of an oxidizing compound agent and an inorganic gelling material, wherein the oxidizing compound agent is: calcium peroxide, calcium persulfate and other oxidizing agents. A variety of mixtures; the inorganic gelling material is a powdery air-hardening or hydraulic inorganic gelling material. The oxidizing compound agent is mixed with the inorganic gelling material according to the ratio of mass fraction 1:5, and after mixing, in a vacuum environment, it is compressed by a tablet machine to form a tablet with a particle size of 5mm, and then compressed under a negative pressure filled with ozone. In the atmosphere, the water-soluble film is wrapped, and the water-soluble film is heated so that the water-soluble film shrinks when heated, and then closely adheres to the outer surface of the particle. The tablet formed under the vacu...

Embodiment 2

[0043] The treatment and repair granules for soil inorganic matter pollution described in Embodiment 2 of the present invention differ from Embodiment 1 in that its composition is mainly composed of an oxidizing compound agent and an inorganic gelling material, wherein the oxidizing compound agent is : a variety of mixing of calcium peroxide and calcium persulfate; wherein the inorganic gelling material is a powdery air-hardening or hydraulic inorganic gelling material, and the oxidizing compound agent and the inorganic gelling material are mixed according to the mass fraction of 1:20 Proportional mixing, after mixing, vibrate through a vibrating sieve to form particles with a particle size of 6mm, and then wrap them with a water-soluble film, and heat the water-soluble film to make the water-soluble film shrink when exposed to heat and closely adhere to the outer surface of the particles.

[0044] The inorganic gel material is selected from the mixture of gypsum and cement, an...

Embodiment 3

[0047] The treatment and restoration granules for soil inorganic matter pollution described in Embodiment 3 of the present invention differ from Embodiment 1 in that its composition is mainly composed of an oxidizing composite agent and an inorganic gelling material, wherein the oxidizing composite agent is : the multiple mixing of calcium peroxide and calcium persulfate; the inorganic gelling material is a powdery air-hardening or hydraulic inorganic gelling material, and the potassium ferrate and the inorganic gelling material are according to the ratio of mass fraction 1:40 Mixing, after mixing, go through a tablet press to form tablets with a particle size of 8mm, then wrap the water-soluble film, and heat the water-soluble film so that the water-soluble film shrinks when it is heated and closely adheres to the outer surface of the tablet.

[0048] The inorganic gel material is preferably gypsum powder.

[0049] The oxidizing compound agent is powder, and the particle size...

Abstract

The invention discloses treating and repairing particles for soil inorganic substance pollution. The ingredients are formed in the mode that an oxidation and composite reagent and inorganic adhesive materials are mainly mixed. A treating and repairing method specifically includes the steps that the oxidation and composite reagent and the inorganic adhesive materials are mixed in the mass ratio of 1:(5-50); after mixing is carried out, particles with the particle diameter of 5-10 mm are formed through vibration of a vibrating screen, or tablets with the particle diameter of 5-10 mm are formed through tabletting of a tablet machine; then the particles or the tablets are packaged with water-soluble films, the water-soluble films are heated and shrunk to be closely compacted to the outer surfaces of the tablets, or the screened particles are packaged through water-soluble capsules in a sealing mode. The treating and repairing particles and the treating and repairing method have the effects of being nontoxic and free of residues, teratogenesis, carcinogenesis, mutagenesis and secondary pollution, and having multiple functions. The economic benefits and the environmental benefits are considered, and the treating and repairing particles and the treating and repairing method can be completely applied to soil treating and repairing operation of multiple inorganic substance pollution in a large area mode.

Description

technical field [0001] The invention relates to treatment and restoration particles and a treatment and restoration method for soil inorganic matter pollution, and belongs to the technical field of agricultural soil treatment. Background technique [0002] In recent years, due to population growth and rapid industrial development, solid waste has been continuously piled and dumped on the soil surface, harmful wastewater has continued to seep into the soil, exhaust gas from automobiles, harmful gases and dust in the atmosphere have continued to fall into the soil with rain. The improvement of the level of agricultural chemistry has caused a large amount of chemical fertilizers and pesticides to be scattered into the environment, resulting in more and more opportunities for soil to be polluted by non-point sources, and the degree is becoming more and more serious; under the influence of soil erosion and wind erosion, etc., The area of ​​pollution continues to expand. [0003]...
