METHOD AND APPARATUS USING PNEUMATIC FRACTURING AND MULTICOMPONENT INJECTION OF A LIQUID OR DRY MEDIA FOR THE TREATMENT NON-NATURALLY OCCURRING SUBSURFACE SOIL AND GROUNDWATER CONTAMINATION

摘要

PURPOSE: A method and a device for increasing efficiency of purifying underground soil contamination and underground water contamination using liquid and solid media of multi components and pneumatic fracturing are provided to prevent a highly contaminated region from being spread to a clean region. CONSTITUTION: Injection points(C) are as contamination region border parts. Compression gas, and liquid or solid media are injected in one direction or several directions from one injection point of the contamination region border part to a contamination region. The compression gas and the media are injected to another border part injection point of the contamination region. The compression gas and the media are injected in one direction or several directions from a border part injection point.
