The "Rebirth" of Heavy Metals: Practical Application of Desen Soil Washing Remediation plant
Soil contaminated by heavy metals is not a useless waste. Through scientific remediation, it can not only eliminate pollution risks but also restore the soil’s development value. Guided by the concept of "remediation + resource recycling", Desen Environmental Soil Washing Remediation plan
Soil contaminated by heavy metals is not a useless waste. Through scientific remediation, it can not only eliminate pollution risks but also restore the soil’s development value. Guided by the concept of "remediation + resource recycling", Desen Environmental Soil Washing Remediation plant promotes the upgrading of contaminated soil treatment—from merely meeting compliance standards to realizing resource utilization.
The remediation plant integrates key modules including washing separation and wastewater treatment, and can be directly driven to contaminated sites for on-site operation. For heavy metal-contaminated soil, the equipment first crushes caked soil into uniform particles, then uses customized washing agents to directionally elute heavy metal ions from the soil. Subsequently, the washing wastewater enters the on-board cyclic treatment system: after precipitation, adsorption, and filtration, heavy metal concentrate is separated and collected centrally, while the treated clean water can be reused for washing—achieving zero wastewater discharge.
During the remediation process, the separated heavy metal concentrate (such as solutions containing copper and nickel) can be refined into industrial raw materials, realizing the recovery of heavy metal resources. The remediated clean soil, depending on the site planning needs, can be used for green space construction, reclaimed as farmland, or used as construction backfill soil—avoiding the waste of soil resources.
Taking the remediation of an old electroplating factory site as an example: after 3 months of operation, Desen Soil Washing Remediation plant not only reduced the heavy metal content in the soil to below the national standard but also recovered approximately 2.3 tons of copper. The remediated soil was used to build an urban park, forming a complete closed loop of pollution treatment, resource recovery, and site "rebirth". This provides a replicable solution for the resource utilization of heavy metal-contaminated soil.
