Abstract:
A particle for treatment and repair of soil contamination is mainly composed of potassium ferrate and an inorganic cementitious material. The inorganic cementitious material is a powdery air-hardening or hydraulicity inorganic cementitious material. The potassium ferrate and the inorganic cementitious material are mixed according to the mass fraction of 1:5-50. After mixing is carried out, the particle with the particle diameter ranging from 2 mm to 5 mm is formed by means of vibration of a vibration screen, the particle is wrapped by a water-soluble film, and the water-soluble film is heated to be shrunk and then is closely attached to the outer surface of the particle. Also disclosed is a method for repairing soil by using the particle. When the particle is mixed with an ozone water solution is adopted.

Claim (Index 6):
A method for using a particle for treatment and repair of soil contamination, the method comprising:\n step  1 , applying the particles for treatment and repair of soil contamination uniformly on a surface of a soil layer; spraying ozone solution on the surface of the soil layer; and then deeply turning the soil layer by using a rotary tillage equipment, so that the particles for treatment and repair of soil contamination are fully contacted with the contaminated soil; and detecting the soil moisture content; step 2, waiting at least 48 h after completion of step 1, applying compound microbial fertilizer and compound microbial strain to the soil layer, wherein the compound microbial fertilizer and compound microbial strain are filled in water-soluble capsules, and detecting soil moisture content of 5 cm-deep soil layer, if the moisture content is less than 15%, then watering to make the moisture content of 15%, plowing the soil so that the compound microbial fertilizer, the microbial compound bacteria and the soil are fully mixed, if the moisture content is higher than 15%, directly plowing the soil so that the compound microbial fertilizer, the compound microorganisms bacteria and the soil are fully mixed, played a continuous repair of contaminated soil; wherein, the particle for treatment and repair of soil contamination, comprises potassium ferrate and an inorganic cementitious material, wherein the inorganic cementitious material is a powdery air-hardening or hydraulic inorganic cementitious material, the potassium ferrate and the inorganic cementitious material are mixed according to a mass fraction of 1:5-50, the mixture is aggregated into particles and then shaken through a shaker to obtain particles with a diameter of 2-5 mm, the particles are then coated with water-soluble films and the water-soluble films are heated to cause the water-soluble films to closely adhere to the outer surface of the particles when they are thermally shrunk, or the particles are packaged by water-soluble capsules.
