Description of the Related Art In recent years, problems relating to soil contamination have been highlighted, and the need for a technology for cleaning and detoxifying contaminated soil has been increasing. In actual fields, purification by microorganisms and detoxification by chemical reactions are being promoted. However, when the degree of contamination is severe, these methods alone are not practical because the processing time and cost increase.
For this reason, a primary treatment such as washing with water is performed before these methods. As a conventional technique in that case, for example, 2
A method is known in which soil and water are mixed and stirred using a shaft mixer or the like to remove contaminants together with water, but the cleaning effect is low and the desired effect is not improved. This is because the physical action applied to the contaminated soil is weak, and the strongly adhered contaminants do not separate from the soil.

It can be widely applied to the separation of liquids and liquids. As the pressurized liquid, high-pressure water or the like pressurized by an appropriate pump is used. The gas injection means for injecting gas into the pressurized liquid may be, for example, a form in which air is sucked by an ejector action of a high-speed water flow, or a form in which air is compressed by a compressor or the like and injected into the high-speed liquid. It may be something. Further, the pressurized liquid is not limited to water, and the gas is not limited to air. As for the separation of each substance released and released from the attached state by the strong physical action of the gas-liquid mixing jet, the separation can be performed by utilizing the difference in specific gravity and the dissolution characteristics as described above. For example, when the impurities are oils or organic solvents, the specific gravity is low and the impurities float up in the separation tank, so that they can be separated by taking out the target substance precipitated downward. In the case of metal ions or organic substances, they dissolve in liquids such as water,
The target object can be taken out by removing it together with the liquid by filtration or the like. Further, when the object to be treated is sand or the like contaminated by water-soluble contaminants, a net-shaped drum such as trommel may be used instead of the separation tank.
