| titleOfInvention | In-situ chemical oxidation remediation method for organic contaminated site soil based on iron cycle regulation |
| abstract | The invention relates to an in-situ chemical oxidation remediation method for organic contaminated site soil based on iron cycle regulation. The method comprises the following steps: adding a mixed solution of natural organic micromolecules and hydrogen peroxide into the soil of the organic pollution field to be repaired, activating naturally-existing iron minerals in the soil by using the natural organic micromolecules to serve as an effective iron source for decomposing the hydrogen peroxide, and efficiently decomposing the hydrogen peroxide into hydroxyl free radicals to realize the in-situ chemical oxidation repair of the soil of the organic pollution field. The method utilizes natural organic micromolecules to activate the naturally-existing iron minerals in the soil, solves the problems that ferrous ions need to be additionally added in the traditional hydrogen peroxide chemical oxidation technology and mass transfer between hydroxyl radicals generated by decomposition of hydrogen peroxide and soil organic pollutants is caused by direct contact, and has the advantages of high efficiency, no selectivity, cost saving, environmental friendliness, no secondary pollution and the like when being used for in-situ chemical oxidation remediation of the soil polluted by the organic matters. |
