Soil vapor extraction: physical methods are used to remove volatile or semi-volatile pollutants. Chemical remediation: solidification / stabilization: by adding chemicals, pollutants are fixed or converted into low-toxicity, low-mobility forms. Chemical washing: using chemical solvents to leach soil, dissolving and extracting pollutants for treatment. Chemical oxidation: injection of chemical oxidants into soil to react with pollutants to achieve purification. Bioremediation: phytoremediation: using plants to absorb, volatilize or transform pollutants, such as plant extraction, plant volatilization, etc. Microbial remediation: using microbial metabolism to degrade organic pollutants or change the form of heavy metals.
