Description

Technical Field

[0001] The invention relates to the technical field of environmental control and pollution control, and in particular to a multi-axis synchronous stirring contaminated soil solidification and restoration device. Background Art

[0002] Solidification / stabilization technology refers to the remediation technology that adds solidification / stabilizers to the soil to change the existing form of heavy metals in the soil, reduce the solubility, mobility, leaching toxicity and bioavailability of heavy metals in the soil environment, reduce the harm to animals and plants caused by rainwater leaching or infiltration, and thus reduce the toxicity of pollutants. Mixing contaminated soil and agents (solidification / stabilizers) ensures sufficient contact and reaction between the agents and pollutants, which plays a very important role in fixation / stabilization technology.

[0003] Soil remediation in my country started relatively late. At present, soil remediation is generally carried out using equipment such as excavators, concrete mixing stations, mechanical mixing buckets, soil conditioners and rotary tillers. When the remediation agent enters the clay soil, the adhesion between the clay soil will hinder the penetration of the remediation agent, resulting in uneven mixing of the clay soil and the remediation agent, affecting the soil solidification effect.
