In the process of industrial development, mercury pollution has become a key focus of environmental governance due to its high toxicity and long-lasting hazards. It spreads through the atmosphere, water, and soil, threatening ecosystems and human health—and the Desen Environmental Washing plant plays a crucial role in addressing this pollution.

1. The Severity and Sources of Mercury Pollution

Mercury pollution stems from a wide range of sources, with chemical engineering, mining, and e-waste disposal being major contributors:

In a small chemical enterprise that used mercury-containing catalysts, outdated processes and inadequate environmental protection facilities led to the direct discharge of large amounts of mercury-contaminated wastewater. This caused mercury levels in aquatic organisms to exceed standards; local fishermen who consumed the contaminated fish subsequently developed symptoms such as neurological disorders and impaired kidney function.

In some non-ferrous metal mining areas, mercury associated with ore is released during mining and crushing processes, polluting soil and air. As a result, mercury levels in surrounding crops exceed safety limits, rendering them unfit for consumption.

2. Core Technology: How Desen Washing plant Removes Mercury

The Desen Environmental Washing plant leverages a unique soil washing remediation technology, based on a dual mechanism of chemical and physical action to eliminate mercury pollution:

Chemical Conversion: A custom-developed washing agent is injected into the contaminated soil. This agent reacts chemically with mercury, converting insoluble mercury compounds in the soil into soluble substances—breaking the strong bond between mercury and soil particles.

Physical Separation: The plant then uses physical processes (washing, screening, and separation) to split the mercury-laden washing solution from soil particles, transferring mercury from the solid soil phase to the liquid solution phase and achieving effective removal.

For example, at the former site of a chemical enterprise, long-term production activities had caused severe mercury overreach in the surrounding soil. After the Desen Washing plant arrived:

It first sampled and analyzed the contaminated soil, then precisely adjusted the washing agent formula based on soil texture, mercury pollution severity, and mercury’s existing forms.

During operation, the plant’s high-efficiency mixing device ensured full reaction between the washing agent and soil. Multi-stage screening was used to initially separate large soil particles from the mercury-contaminated washing solution.

Advanced solid-liquid separation equipment (e.g., filter presses) then achieved complete separation of the solution and soil. The cleaned soil, after passing compliance testing, was safely backfilled.

3. Practical Advantages: Efficiency, Flexibility, and Environmental Protection

In real-world applications, the Desen Environmental Washing plant demonstrates prominent advantages:

(1) Flexible Mobility & Space Efficiency

Adopting an integrated, mobile design, it occupies a small footprint and can adapt to complex site conditions—whether narrow urban contaminated plots or remote mine pollution areas. It enables rapid deployment, significantly shortening the remediation cycle and reducing transportation and construction costs.

(2) Closed-Loop Treatment to Avoid Secondary Pollution

Equipped with an advanced water treatment module, the plant conducts in-depth processing of mercury-contaminated washing solutions. Using technologies such as chemical precipitation, ion exchange, and membrane filtration, it removes mercury from the solution, allowing the treated water to be either recycled for washing or discharged up to standard. This achieves a win-win of efficient resource utilization and environmental protection.

A notable case is a non-ferrous metal mining area: after using the Desen Washing plant for soil mercury remediation, third-party testing confirmed that soil mercury levels dropped significantly to meet national soil environmental quality standards, and the surrounding ecological environment gradually recovered.

As a key link in the heavy metal mercury pollution control chain, the Desen Environmental Washing plant focuses on blocking secondary pollution at the source, providing efficient and practical solutions for key fields such as chemical engineering, mining, and e-waste disposal. It not only reduces the risk of mercury pollutant spread through precise cleaning but also safeguards the surrounding ecology and residents’ health through tangible remediation results. By laying a solid foundation for environmental restoration and sustainable development in polluted areas, it continues to inject strong momentum into winning the battle against heavy metal pollution.
