Due to long-term industrial activities, the smelter yard has accumulated a large amount of waste residue containing heavy metals such as arsenic, lead, and chromium. These waste residues not only cause serious pollution to the soil and groundwater, but may also affect human health through the food chain. For example, arsenic is a common heavy metal pollutant, which is extremely toxic. Long-term exposure can cause health problems such as skin lesions and cancer. In addition, heavy metals in smelting waste residues are prone to migration and diffusion under natural conditions, further exacerbating the scope and degree of pollution.

Desen washing equipment is a special equipment designed for the remediation of heavy metal-contaminated soil. It uses chemical washing technology to inject special washing agents into the contaminated soil to desorb heavy metals from the surface of soil particles and transfer them to the liquid phase, thereby separating and removing pollutants. This technology has the following significant advantages:

High efficiency: Desen washing equipment can quickly penetrate into the soil particles and convert heavy metals from solid low-concentration pollutants to liquid high-concentration pollutants, which is convenient for subsequent centralized treatment.

High degree of automation: The equipment integrates an automatic control system, and realizes intelligent operation from soil feeding to washing liquid separation, which greatly shortens the construction period and reduces labor costs.

Wide range of applications: Desen washing equipment is suitable for a variety of complex contaminated sites, including high-viscosity soil, sandy soil and composite contaminated soil.

Environmental protection: The waste liquid after washing can be recycled after treatment, reducing the risk of secondary pollution.

Desen washing equipment has been successfully applied in many heavy metal contaminated sites. For example, in a steel plant site restoration project, Desen equipment reduced the pollutant content in the soil to below the safety standard in just half a year, significantly shortening the traditional restoration cycle. In addition, in the arsenic pollution control of a smelter yard, Desen equipment successfully reduced the arsenic content in the soil to below the national standard through the application of composite washing agents, restoring the ecological function of the soil.

Desen Environment continues to optimize the design and process flow of washing equipment. For example, its modular integrated ex situ washing and remediation system has functional modules such as screening, scrubbing, grading, and dehydration, which can flexibly respond to contaminated sites of different sizes and types. At the same time, the company has also developed a mobile washing and remediation station to further improve the flexibility and applicability of the equipment.

In the future, Desen Environment will continue to explore more efficient eluent formulas and intelligent management platforms to further improve remediation efficiency and reduce costs. At the same time, the company will also strengthen cooperation with the government, enterprises and scientific research institutions to jointly promote the development and application of heavy metal pollution control technology in my country.

The pollution control of heavy metal waste slag in smelter yards is a complex and arduous task. Desen washing equipment, with its high efficiency, intelligence and environmental protection, provides a practical solution to this problem. Through technological innovation and practical accumulation, Desen Environmental Technology Co., Ltd. is becoming one of the leading companies in the field of heavy metal pollution control in my country. In the future, with the application and promotion of more advanced technologies, my country's soil remediation business will usher in a brighter development prospect.
