What is soil remediation

Contaminated soil remediation refers to physically, chemically and biologically transfer, absorb, degrade and transform pollutants in soil, which concentration can be reduced to acceptable levels, or turn toxic and harmful pollutants into harmless substances. Fundamentally, the technical principles for contaminated soil remediation may include:
1.Change the existing form or the mode of combining with the soil of pollutants in soil, reduce the mobility and bioavailability in the environment.
2.Reduce the concentration of harmful substances in the soil.

The United States invested nearly $100 billion in contaminated soil restoration in 1990s. The theory and technology of contaminated soil remediation have become the frontiers of environmental science and technology research. The process of soil restoration is quite long, the need to solve the problem of soil pollution, it needs scientists of different disciplines, such as soil science, agronomy, ecology, biogeochemistry, marine science, and efforts from involve agricultural, forestry, fishery and other related production units and government.

Soil pollution in China has been a threat to the sustainable use of land resources and the ecological security of agricultural products. Farmland contaminated by organic pollutants throughout the country has reached 36 million hectares, pollutant types including petroleum, PAHs, organochlorine pesticides, etc.; because of serious oil pollution caused by oil field exploitation 10 thousand hectares, the petroleum refining and chemical industry also contaminated large areas of land. The heavy metal contamination of 20 million hectares, which seriously polluted the land more than 700 thousand hectares, of which 130 thousand hectares land exceed the standard CD content and are forced to abandon. Because of this, contaminated soil remediation research is undergoing a transition from laboratory research to practical stage, and is about to enter a rapid and comprehensive period of governance.




PARFECT provides in situ soil mixing equipment, and injecting liquid or solid stabilization agent into the soil while mixing the soil, which can be applied to contaminated soil remediation and foundation consolidation project.
