Title:
METHOD FOR OPTIMIZING AND REPAIRING SOIL AND GROUNDWATER BY IN SITU CHEMICAL OXIDATION AND HIGH PRESSURE INJECTION
Document Type and Number:
WIPO Patent Application WO/2017/219790
Kind Code:
A1
Abstract:
Disclosed is a method for optimizing and repairing soil and groundwater by in situ chemical oxidation and high pressure injection, belonging to the technical field of methods for soil and groundwater in situ repairing. (1)Field experiments are carried out to determine the diffusion radius of the injection agent for the typical stratum, the maximum grouting amount in single hole per linear meter and the injectable parameters. (2)Encrypted supplementary survey, analysis for soil and groundwater data is divided, according to the spatial distribution, into: four concentration main partitions and eight concentration subpartitions. (3)By optimizing the grouting amount in single hole per linear meter, the formulating concentration of the oxidant and the parameters of the formula in each partition, the optimization of the addition ratios of the repairing agent in each partition is realized, wherein the specific construction performance is realized to adjust the lifting speed of the high pressure injection drill pipe during the injection process, and ultimately achieves the purpose of reducing the addition ratio parameter of the agent in the repairing plot. The method is applicable to the serious and deep pollution of organic contaminated soil and groundwater, able to solve the problems of high cost of agents and agents residue in the engineering of in situ chemical oxidation repairing, and has a relatively strong engineering operability.
