SOIL RENOVATION METHOD FOR PURIFICATION SOIL

摘要

The present invention relates to a soil improvement method for soil purification, which recycles the purification soil by increasing the engineering value of the purification soil by mixing inorganic ingredients with the purification soil which is purified by removing remaining contaminants from contaminated soil. The present invention comprises the following steps: mixing inorganic ingredients with the purification soil in order to increase the engineering value of the purification soil purified by removing the remaining contaminants; passing the purification soil mixed with the inorganic ingredients through a sieve having multiple meshes and filtering the purification soil to have a fine size; and measuring the engineering value and particle size of the purification soil. In the case that the particle size of the purification soil does not fit, the purification soil is filtered once more; when the particle size of the purification soil is fine and the engineering value is incomplete, the inorganic ingredients are added and mixed again with the purification soil, and the state of the purification soil mixed with the inorganic ingredients is checked.
