Due to the complexity and diversity of soil pollution, a single soil washing technology often fails to achieve the ideal remediation effect, and needs to be coupled or combined with other remediation technologies to form a comprehensive remediation solution. For example, soil washing technology can be coupled or combined with physical remediation technology (such as thermal desorption, multiphase extraction, etc.), biological remediation technology (such as microbial degradation, plant extraction, etc.), chemical oxidation/reduction technology, etc., to achieve the synergistic removal of pollutants of different types and degrees.

Desen washing equipment uses clean water or chemical washing agents to leach (water) heavy metal/PHCs contaminated soil, dissolve or migrate pollutants into clean water or chemical washing agents, wash and grade clean sand and gravel aggregates above 0.15mm, and effectively reduce the pollutant content in the filter cake. The washing wastewater enters the water treatment system and is recycled and reused. This technology is not only suitable for single heavy metal contaminated sites, but also successfully solves the problem of composite contaminated soil remediation in combination with other remediation processes.

my country's remediation sites are mainly located in developed coastal cities, as well as in Hunan and Hebei, where pollution is serious. Site pollution types include organic pollution (43%), heavy metal pollution (30%), and complex pollution (25%). At present, the treatment method of soil remediation in my country focuses on complex remediation. Desen washing equipment is efficient and intelligent, and can significantly reduce the content of pollutants in the soil in a short period of time, which buys valuable time for land reuse and ecological restoration. Globally, Desen Environment has many successful washing cases. Whether it is urban brownfields, ditch sludge, or oil-bearing land management, Desen washing equipment can be seen.

The research and development of efficient and environmentally friendly equipment can not only improve the efficiency of site remediation, but also promote the progress and development of site remediation technology worldwide. As Desen Environment continues to increase its R&D efforts to carry out technological innovation and continue to deepen the application of equipment, Desen washing equipment will contribute more to global environmental remediation and jointly protect our green home!
