Embodiment 1

[0042] The treatment and restoration granules for soil organic matter pollution described in 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: ferrous chloride, ferrous sulfate 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, the tablet machine is pressed to form a tablet with a particle size of 5mm, and then in a negative pressure atmosphere full of ozone In the process, the water-soluble film is wrapped, and the water-soluble film is heated so that the water-soluble film is tightly attached to the outer surface of the pressed tablet after being heated, and then the pressed tablet is packaged in a water-so...

Embodiment 2

[0046] The treatment and restoration granules for soil organic matter pollution described in Embodiment 2 of the present invention are different from Embodiment 1 in that their components are mainly composed of an oxidizing compound agent and an inorganic gelling material, wherein the oxidizing compound agent is: Various mixing of oxidizing agents such as ferrous chloride, ferrous sulfate; Wherein the inorganic gelling material is powdery air-hardening or hydraulic inorganic gelling material, and the oxidizing compound agent and the inorganic gelling material are according to mass fraction 1: The ratio of 20 is mixed, and after mixing, it is compressed by a tablet machine, then wrapped in a water-soluble film, and the screened granules are packed in a water-soluble capsule.

[0047] The inorganic gel material is selected from a mixture of diatomite and attapulgite, and the mixing ratio is 1:1.

Embodiment 3

[0050] The treatment and repair granules for soil organic matter pollution described in Embodiment 3 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 oxidizing agents such as ferrous chloride and ferrous sulfate; the inorganic gelling material is a powdery air-hardening or hydraulic inorganic gelling material, and the potassium ferrate and the inorganic gelling material are mixed according to the mass fraction of 1:40 After mixing, the tablets are pressed by a tablet machine to form tablets with a particle size of 8 mm, and then wrapped with a water-soluble film, and the water-soluble film is heated to make the water-soluble film shrink when heated and fit tightly on the outside of the tablet. Surface; the tablets are packaged in water-soluble capsules.

[0051] The inorganic gel material is preferably att...

Abstract

The invention discloses a treatment and repair particle for soil organic matter pollution. Its composition is mainly composed of an oxidative compound agent mixed with an inorganic gelling material, specifically comprising: an oxidative compound agent and an inorganic gelling material according to the mass fraction of 1:5-50 Mixed according to the ratio; after mixing, it is shaken by a vibrating sieve to form particles with a particle size of 5-10mm, or compressed by a tablet machine to form tablets with a particle size of 5-10mm; then wrapped in a water-soluble film, and the water-soluble film The water-soluble film is heated to shrink and adhere closely to the outer surface of the granules or tablets, or the screened granules are sealed and packaged in water-soluble capsules. The treatment and repair granules and the treatment and repair method provided by the present invention have the effects of non-toxicity, no residue, no teratogenicity, no carcinogenicity, no mutagenicity, no secondary pollution, and multiple functions in one method. This method takes both economic and environmental benefits into account, and can be widely used in soil treatment and restoration work polluted by various organic pollutants.

Description

technical field [0001] The invention relates to a treatment and repair particle for soil organic matter pollution and a treatment and repair method, which belong 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] In 2010, ...
