METHOD FOR PURIFYING CONTAMINATED SOIL/GROUNDWATER USING NANO-SCALE ZERO-VALENT IRON AND DIRECT INJECTION-PERMEABLE REACTIVE BARRIER

摘要

PURPOSE: A method for purifying contaminated area containing contaminated soil or underground water is provided to reduce cost required for installation using a direct injection-permeable reactive barrier based technique. CONSTITUTION: A method for purifying contaminated area using nZVI and a direct injection-permeable reactive barrier based technique. A contaminated area containing contaminated soil and underground water is classified into highly contaminated area and lowly contaminated area. An injection wall, a monitoring well, and a multi-monitoring well are installed at the contaminated areas. The nZVI is injected through the injection well. The effective radius and purifying efficiency and harmness of the contaminated areas are monitored using the monitoring well and the multi-monitoring well.
