THE METHOD FOR BIOREMEDIATION OF CONTAMINATED SOIL USING MICROBUBBLE GENERATOR

摘要

PURPOSE: Micro-bubble surface-active water and a method for restoring the contaminated soil using the same are provided to reduce a purification time by securing oxygen for decomposing microorganism. CONSTITUTION: During a raw-material supplying step(100) and a micro-bubble generating step(200), 5 to 10 parts by weight of non-ionic surfactant is mixed to 100 parts by weight of water. Oxygen is added to the mixed water based on the contaminated degree of soil. A stirring operation is performed to generate micro-bubble. Micro-bubble surface-active water is prepared. The micro-bubble surface-active water is supplied to contaminated soil.
