  • Publication number: 20240359223
    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.

  • Patent number: 10787865
    Abstract: An in-situ injection of soil and groundwater—high pressure rotary jet grouting in-situ remediation system and method. The system has an agent dispensing station, high pressure grouting pump, air compressor, rotary jet grouting drilling machine, second double-pipe water flow joint, automatic lifting mechanism for grouting drill pipe of rotary jet grouting drilling machine, high pressure jet drill pipe, inner tube for high pressure jet triple drill pipe, outer tube for high pressure jet triple drill pipe, agent jet nozzle, an air jet nozzle, cemented carbide block and a drill bit. Parameters are arranged according to the triangle method to ensure that the remediation area is covered within the diffusion radius of the agent. After positioning the GPS measuring point, a guided-boring rig is positioned at the center of the injection point.

  • Patent number: 10682680
    Abstract: An in-situ chemical oxidation high pressure injection optimization remediation method for soil and groundwater. A field test determines the diffusion radius of the injection agent in a typical formation, the maximum single-hole grouting amount per linear meter and the injectability parameter. Density-increased supplementary investigation, soil and groundwater data analysis, is divided by spatial distribution into four concentration main partitions, eight concentration sub-partitions. By optimizing the single-hole grouting amount per linear meter, the preparation concentration of the oxidant, and the parameters of the formulation of each partition, the optimization of the dosing ratio of remediation agent of each partition is achieved. The specific construction performance is to adjust the lifting speed of the high pressure injection drill pipe during the injection process for finally achieve the purpose of reducing the dosing ratio parameters of the agent in the remediation plot.
