In the current era of high-speed industrial development, heavy metal pollution has become a global environmental governance challenge. Especially in areas where tailings are piled up, due to the long-term accumulation of mining waste, heavy metals are highly concentrated, causing severe damage to the soil and water ecosystem and threatening the safety of the surrounding environment and human health.

As an efficient pollution control method, the washing and remediation technology separates and extracts heavy metals from soil and tailings residues through dissolution, complexation, or displacement reactions between the washing agent and heavy metals. Then, with the help of professional separation technology, it achieves the efficient separation of the washing solution containing heavy metals from the clean solid waste, thus significantly reducing the total amount of heavy metals in the polluted area. Compared with traditional phytoremediation and solidification/stabilization technologies, the washing and remediation technology breaks through the limitations of the long remediation cycle of phytoremediation (usually taking several years to decades) and the fact that the solidification/stabilization technology does not truly remove heavy metals, posing a risk of secondary pollution. It can complete the deep purification of severely polluted areas in a short time and quickly reduce the content of heavy metals in soil and tailings residues.

Desen's washing equipment has achieved a technological breakthrough in the field of tailings residue treatment by virtue of its innovative process flow. Through four core processes of scrubbing, soaking and classification, concentration, and dewatering, this equipment conducts refined treatment of tailings residues: In the scrubbing process, mechanical agitation and water flow scouring are used to strip the heavy metal pollutants on the surface of the tailings residues; during the soaking and classification process, the chemical reaction of the washing agent is utilized to dissolve the internal heavy metals and classify them according to particle size; the concentration and dewatering steps efficiently separate the washing solution containing heavy metals from the solid tailings residues, significantly reducing the subsequent treatment cost and difficulty. At the same time, it creates conditions for the recovery of heavy metals and the reuse of tailings resources.

After being treated by Desen's washing equipment, part of the tailings residues can be reused as raw materials for building materials in production; the separated heavy metals, after being refined and processed, can also return to the industrial production process, truly achieving the dual goals of "pollution reduction" and "efficiency improvement" and realizing the organic unity of environmental benefits and economic benefits.

In the future, with the continuous iterative upgrading of technology, the washing and remediation technology and Desen's washing equipment will play a more important role in the field of environmental governance, contributing crucial strength to promoting the construction of ecological civilization and achieving sustainable development.
