In a method of treating waste soil, carbon-containing substances are added into the soil according to percentages of different organic substances contained in the soil; the soil is then isolated from external air while being fed into a reaction chamber; high-temp hot gas is sent from a first combustion chamber into a second combustion chamber to heat the reaction chamber and a high-temp steam generator; high-temp steam produced by the high-temp steam generator is introduced into the reaction chamber, and maintained in thermal balance with the soil in the reaction chamber, so that mercury, organic substances, and dioxin contained in the soil are distilled and carried away by the high-temp steam; and fuel gas and fuel oil are separated from the steam for sending to a burner for producing the high-temp hot gas; and the treated soil is isolated from external air while being discharged, and quickly cooled down.
