Abstract
The present invention provides a method for in-situ remediation of contaminated soil through multi-technology coupling. The remediation method comprises the following steps: preheating the soil at a contaminated site by using in-situ thermal conductive heating (TCH) technology, and then performing multi-phase extraction; and performing a cycle of injecting hot steam, multi-phase extraction, and injecting an oxidizing agent into the soil at the contaminated site. A system for in-situ remediation of an organically contaminated soil based on the aforementioned method for in-situ remediation of the organically contaminated soil includes a heating well, an injection well, and an extraction well. The heating well is connected to an in-situ thermal conductive heating system, and used for preheating of the soil at the contaminated site. The injection well is connected to an in-situ injection system, and used for injecting the hot steam and the oxidizing agent. The extraction well is connected to a vacuum extraction system, and used for the multi-phase extraction of the contaminated site. In the present disclosure, a pollutant removal rate of the organically contaminated soil is greatly increased by means of a combination of multiple technologies coupled together.
