The remediation of nickel-contaminated soil has become a critical task in environmental protection efforts. Nickel pollution not only impairs soil quality and crop growth but also poses long-term hazards to groundwater and the surrounding ecological environment. Traditional remediation methods often fall short when dealing with complex nickel-contaminated soil conditions. The emergence of the Desen Soil Washing Remediation plant has broken through this dilemma, ushering in a new era of nickel-contaminated soil remediation.

The Desen Soil Washing Remediation plant integrates the advantages of multiple remediation technologies—including physical, chemical, and biological approaches—to form a unique and highly efficient remediation system.

In terms of physical remediation, it conducts pretreatment processes such as soil screening. This step increases the contact area between the soil and the washing solution, laying a solid foundation for subsequent chemical washing.

Chemical remediation serves as the core technology of the Desen plant. It adopts specially developed washing solutions that target the chemical properties of nickel contaminants. Through processes like desorption and chelation, nickel is dissolved from soil particles and transferred into the washing solution, effectively separating the pollutant from the soil matrix.

Additionally, the Desen Soil Washing Remediation plant innovatively incorporates the concept of biological remediation. Specific microbial communities are added to the washing solution; by leveraging the metabolic activities of these microbes, the conversion and removal of nickel contaminants are further promoted, significantly enhancing the overall remediation effect.

This integrated multi-technology remediation approach endows the Desen Soil Washing Remediation plant with distinct advantages in nickel-contaminated soil treatment. It not only efficiently removes nickel contaminants from the soil but also has minimal impact on soil structure and fertility—facilitating the rapid restoration of the soil ecosystem.

In a soil remediation project at a nickel mine mining area, the Desen plant successfully remediated a large area of nickel-contaminated soil using this multi-technology integration method. After remediation, the nickel content in the soil met the standard requirements. Moreover, the soil’s microbial activity and fertility were effectively restored, the surrounding vegetation regained vitality, and the ecological environment showed significant improvement.

With its innovative technology, outstanding remediation results, and excellent environmental performance, the Desen Soil Washing Remediation plant has brought new concepts and methods to nickel-contaminated soil remediation, opening a new era in this field. It is bound to play an even more important role in the soil remediation sector in the future.
