Physical separation technology: According to different particle size and shape of soil particles, through different sizes and shapes of mesh screens and filters to separate the pollutants bound to the pollutants.

In situ fixation stabilization technology: the remediation substances are injected into the contaminated soil, mixed with a large spiral mixing device or drill, and covered with pollution-free soil to fix the soil pollutants in situ, and do not participate in the material circulation of the ecosystem

Soil performance improvement remediation technology: Through the method of improving soil properties, the application of amendments (such as soil pH and REDOX potential) is targeted to transform pollutants into difficult to migrate, low active substances or remove from the soil.

Soil chemical oxidation technology: through the oxidation reaction with pollutants in the soil, such as oxidizing agents and catalysts, so that pollutants degrade or transform into low-toxicity and first Dongxing products.

Phytoremediation technology: the use of agricultural technology to improve the chemical and physical constraints of contaminated soil that are unfavorable to plant growth, make it suitable for planting, and directly or indirectly absorb, volatilize, separate or degrade pollutants by planting preferred plants and their rhizosphere microorganisms, so as to restore and rebuild the natural ecological environment and vegetation landscape.

Ecological containment and control engineering: The use of engineering technology to prevent the diffusion of pollutants in the soil, prevent the migration of pollutants, and reduce its impact on the surrounding environment to a minimum.
