Soil is the main deposition receptor and storage carrier for heavy metal pollution from the outside. After heavy metals enter the soil from various channels, their mobility in the soil is reduced. At the same time, they are not easily degraded by microorganisms or leached with water. They can only accumulate and migrate in the natural state. Therefore, the characteristics of heavy metal pollution are long-term, hidden, biodegradable and bioaccumulative.
At present, there are many methods for the remediation of heavy metal contaminated soil at home and abroad. The remediation technology of heavy metals in soil in China is mainly about the research on heavy metal pollution in acidic soil in southern my country. There are few related studies on the remediation of heavy metal pollution in calcareous soil in the north, and the technical methods are immature. The traditional remediation technology for heavy metals in acidic soil in the south first adopts the addition of alkaline neutralizers to fix heavy metals and reduce their biological effectiveness. The pH value of calcareous soil is high, and heavy metals in the soil are mostly in carbonate-bound state. The remediation effect of traditional alkaline materials is poor. Therefore, it is urgent to develop new technologies and methods for calcareous heavy metal contaminated soil.
Chemical washing technology has the advantages of good remediation effect, short remediation time and low cost for soils with high concentrations of composite heavy metal pollution, and green remediation can be achieved through the selection of washing agents, which is needed for heavy metal remediation in the future.
Desen integrated soil washing equipment includes a mobile soil washing and remediation equipment. It is an integrated design product customized and developed by Zhengzhou Desen Environmental Technology Co., Ltd. based on many years of practical experience in soil remediation projects and drawing on advanced washing technologies and equipment at home and abroad. Integrated soil washing equipment can be widely used in various types and degrees of contaminated soil, including soil washing and remediation of organic/heavy metal contaminated sites such as chemical, pharmaceutical, metallurgical, and steel. It can also be used for project sites with various types of physical washing, washing, and grading requirements such as residual mud in ditch, river silt, shield mud, and mine remediation.
The integrated soil washing equipment is equipped with a 5G module intelligent operation platform, which can realize high automation and intelligence of the equipment, and an intelligent cloud management platform. It can flexibly switch between multiple interfaces on the PC and mobile terminals, realize remote operation of the equipment, and conduct data analysis. The remediation of heavy metal contaminated soil is extremely important. Only by ensuring that the soil can be restored can the level of ecological environmental protection and people's quality of life be improved to the greatest extent. Desen integrated soil washing equipment is the well-deserved first choice.
