Thermal power plant sites are typical examples of industrial legacy land. Decades of operation leave behind heavy metals, PAHs, and other contaminants that severely degrade soil health. To address these challenges, Desen Environmental has developed a specialized soil washing system engineered to solve the complex pollution issues commonly found in decommissioned power plant locations—providing a robust, high-efficiency solution for ecological restoration and industrial site transformation.

Precision-Engineered for the Complex Pollution Profile of Former Power Plant Sites
Thermal power plant soils often contain diverse pollutants with irregular concentrations. To address this, the system is equipped with a customized washing-agent injection module designed to target heavy metals and organic contaminants.
Through dual-action chelating and emulsifying mechanisms, the system breaks the strong bonds between pollutants and soil particles, enabling fast and efficient contaminant removal.
An intelligent screening and pre-treatment module separates slag, metal fragments, and other debris, ensuring a uniform reaction environment and significantly improving washing performance.
High-Efficiency Solid-Liquid Separation and Closed-Loop Circulation
The integrated solid-liquid separation system achieves over 95% separation efficiency, quickly isolating clean soil from contaminated washing liquid.
The treated soil meets moisture and quality standards for redevelopment uses such as construction land and landscaping.
The closed-loop washing liquid treatment unit—utilizing adsorption, oxidation, and other multi-stage purification processes—achieves 85–98% pollutant removal, allowing fully treated water to be safely reused in the washing cycle.
This enables true zero-discharge remediation, fully aligning with environmental compliance requirements.
Flexible Deployment, Shorter Construction Cycles, and Lower Remediation Costs
In real remediation projects at former power plant sites, Desen Environmental’s soil washing system demonstrates exceptional adaptability and operational flexibility.
The system can be scaled according to site area and contamination intensity.
Compared with traditional remediation technologies, the construction timeline is reduced by more than 30%, significantly lowering treatment costs.
After full remediation, soil quality indicators meet national environmental standards, enabling the site’s transformation from a “polluted industrial area” into a usable ecological or redevelopment space.
Driving Eco-Transformation and Urban Renewal with Innovation
By leveraging advanced soil washing technology, Desen Environmental tackles the long-standing challenges of industrial legacy site remediation.
This solution not only safeguards soil ecological security but also injects sustainable momentum into urban renewal and industrial-site revitalization—reflecting the company’s commitment and responsibility as a leading environmental technology provider.
