REMEDIATION METHOD OF OIL CONTAMINATED SOIL AND GROUNDWATER BY SEQUENTIALLY COMBINED TREATMENT OF HYDROGEN PEROXIDE, ULTRAVIOLET RAY AND OIL DEGRADABLE MICROORGANISMS SATISFYING BOTH SUPERIOR PURIFICATION AND ECONOMIC EFFICIENCY

摘要

PURPOSE: To provide a remediation method of oil contaminated soil and groundwater, which is capable of satisfying both superior purification efficiency and economic efficiency by sequentially linking chemical purification by hydrogen peroxide, removal of residual hydrogen peroxide by ultraviolet treatment and biological purification by oil degradable microorganisms. CONSTITUTION: The remediation method of oil contaminated soil and groundwater comprises a step of injecting a hydrogen peroxide solution into an oil contaminated area; a step of extracting a hydrogen peroxide treated water from the area; a step of treating the treated water by ultraviolet rays; a step of reacting the ultraviolet treated water with microorganisms in a microbe reactor; and a step of discharging the microorganism treated water or injecting the microorganism treated water into the area again. The remediation system of oil contaminated soil and groundwater comprises a hydrogen peroxide tank(1), a hydrogen peroxide injection well(2), a first treated water extraction well(3), a first treated water extraction pump, a first treated water transfer pipe(4), a ultraviolet treater(5), a ultraviolet treated water transfer pipe(6), a microbe reactor(7), a second treated water transfer pipe(8), a sediment tank(9), and a controller(10).
