Pretreatment equipment and method for remedying soil contaminated by crude oil with subcritical water

摘要

The present invention relates to a pretreatment apparatus and a pretreatment method. More particularly, the present invention relates to a pretreatment apparatus and a pretreatment method, and more particularly, to a method and apparatus for removing heavy oil components in a soil, And a pretreatment method. The pretreatment apparatus for purifying crude oil contaminated soil according to the present invention comprises a process water storage tank storing process water, a heater for heating the process water discharged from the process water storage tank, a heavy oil component A solvent tank for storing a solvent for allowing the solvent to pass through the heater, a process water passed through the heater, a solvent stored in the solvent tank, and a soil contaminated with crude oil contaminated with the crude oil contaminated soil are mixed and agitated in a stirrer, A collecting soil storage tank for storing the granulated soil selected by the sorter, and a micro-sediment storage tank for storing the selected micro-soil from the sorter, And a fine-particle-to-be-stored in the fine-particle-storing tank is transferred to the inside by the transfer pump, And a strainer for separating liquid.
