PURPOSE: A soil remediation system for eliminating VOCs/oil from contaminated soil is provided to solve serious environmental pollution that would be contributed to laundry solvents, semiconductor processes, and oil stations. CONSTITUTION: The soil remediation system consists of a plurality of wells(100) for collecting oil moved along with the flow of sprayed water; a plurality of pumps(200) for transferring collected wastewater through a pipe(210) in case wastewater reach a predetermined water level; a flow equalization tank(300) which is coupled with the pipe(210) for receiving transferred wastewater; an oil separator(400) in which oil is floated by an air bubbler, an oil concentrating tank(410) is installed at a certain elevation of the oil separator, and further a precipitation tank is installed to dehydrate sludge after injecting coagulants; an ozone oxidation tank(500) into which treated wastewater is injected being mixed with H2O2 and ozone; a plurality of sprinklers(600) which are connected with the ozone oxidation tank for spraying a certain quantity of treated wastewater on contaminated area after adding H2O2 as an oxygen supplier and microorganisms for decomposing oil. |
