The harm of heavy metals to soil is mainly reflected in the following aspects:
Toxicity. Heavy metals such as lead, cadmium, mercury, etc. are toxic to microorganisms, plants and animals in the soil, which will destroy the balance of the soil ecosystem and affect the biodiversity and ecological functions of the soil. Plant absorption. Heavy metals can be absorbed by plants in the soil and enriched in the plant body, and then enter the food chain, posing a potential threat to the health of humans and animals. High concentrations of heavy metals will inhibit the growth and development of plants and reduce the yield and quality of crops.
Degradation of soil quality. The accumulation of heavy metals will lead to a decline in soil quality and affect the fertility and structure of the soil. The presence of heavy metals will change the physical, chemical and biological properties of the soil, reduce the soil's water retention capacity, aeration and fertility, and lead to soil degradation.
Soil pollution spread. Heavy metals have a strong ability to migrate and diffuse in the soil, and will further pollute the surrounding environment through the migration of soil particles, the scouring of water flow and the diffusion of aerosols, causing pollution to groundwater, rivers and lakes and other water bodies.
In order to protect the soil environment and human health, the monitoring and control of heavy metal pollution should be strengthened, and effective measures should be taken to reduce the emission and accumulation of heavy metals.
Soil washing technology transfers the contaminated soil from the contaminated area to the adjacent site or reactor, washes the excavated contaminated soil with a washing agent, and transfers the organic and inorganic pollutants in the soil particles to the liquid phase through desorption, chelation, dissolution, complexation and other effects, or screens out the pollutants concentrated on a certain soil particle size for the next step of treatment, so that the contaminated soil is purified or reduced.
Desen's integrated soil washing equipment can be used for washing and remediation operations of various contaminated sites such as chemical smelters, organic contaminated sites, gas station sites, and heavy metal contaminated sites. It is suitable for washing operations of clay-like insoluble soils; the on-site washing effects of several soil washing and remediation projects show that the washing and remediation equipment can achieve the target value after the contaminated soil is remediated.
The supporting capacity range can reach 10-100 tons/hour, which can meet the requirements of multi-capacity projects. Customized process design and equipment matching are carried out according to sample data such as pollution indicators of customer remediation projects. It can realize PLC intelligent control of the whole process from feeding metering, scrubbing and grading, efficiency-enhancing elution, to mud concentration, mud filtration, etc. In addition, Desen integrated elution equipment can be upgraded and updated according to the actual needs of customer projects. There are docking interfaces reserved between modules, and modules can be added or removed at any time according to project needs. Everything is guided by customer needs!
