摘要
An in situ waste treatment system for contaminated soil employs a high temperature energy probe which is lowered into a borehole casing that has been inserted into the contaminated soil. The energy probe is activated and then melts surrounding region of the contaminated soil. The probe is raised and continues to melt a cylindrical column of soil that surrounds the borehole casing. Oxygen is introduced into the molten material so that organic and metallic components thereof are oxidized. In basaltic soils superheating and nucleation materials are introduced to enhance formation of a crystalline structure in the contaminated soil as it solidifies. Increased crystallinity makes the resultant solidified basaltic materials more resistant to leaching by ground water. Other types of contaminated soils are treated with waste modifiers to produce optimum leach resistance of the resultant resolidified soil.
