A solidification and stabilization system for soil remediation

Abstract

The invention relates to a solidification and stabilization system for soil restoration, comprising a crushing system, a screening system, a drying system, a soil solidification system and a maintenance system arranged sequentially from front to back; the crushing system is used for crushing soil raw materials; the crushing system There is a first conveying device between the screening system and the screening system; the screening system is used to screen the crushed soil raw materials; there is a second conveying device between the screening system and the soil solidification system; the drying system is set on the second conveying device On the conveying track, it is used to dry small particle raw materials; the soil curing system is used to add curing and stabilizing agents to the dried soil and mix them evenly; a third conveying device is installed between the soil curing system and the maintenance system. Advantages: The structural design is reasonable and compact, which can effectively reduce the floor space. The whole system is safe and effective, and can continuously treat heavy metal-contaminated soil.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a solidification and stabilization system for soil restoration. Background technique [0002] Solidification and stabilization technology refers to a method of combining heavy metal-contaminated soil with a specific binding agent, so that the heavy metals in the soil are fixed by the agent, making it in a stable state for a long time and reducing its mobility. This method is widely used in the rapid and controlled remediation of heavy metal-contaminated soils, and has significant advantages in the simultaneous treatment of multiple heavy metal-contaminated soils. [0003] Solidification stabilization technology is currently widely used in the remediation process of heavy metal contaminated soil in my country because of its simple operation process, good treatment effect, low price, and perfect technical theory. [0004] Factors affecting the effect of curing and stabili...

Problems solved by technology

However, due to the shallow groundwater level in some polluted sites, the water content of the excavated soil is above 30%. If this type of soil is not dried, it will not only block the curing and stabilization system, but also reduce the curing efficiency of the curing agent.
