A kind of ex-situ solidification and stabilization soil remediation equipment and soil remediation method

Abstract

The invention relates to the technical field of soil ex-situ restoration, and discloses an ex-situ solidification and stabilization soil restoration equipment, comprising a base plate, a support rod 1 is fixedly installed on the top surface of the base plate, and the top surface of the support rod 1 is fixedly installed There is a repair room, a discharge pipe and a motor 1 are fixedly installed on the bottom surface of the repair room, a ball screw is fixedly sleeved at the output end of the motor 1, and a positioning rod is fixedly installed on the top surface of the inner cavity of the bottom plate. The ex-situ solidification stabilized soil remediation equipment and its use method cannot pass through the round holes on the surface of the screen to stay above the screen through the stones and other construction waste, and the motor drives the ball screw to rotate, and the screen meshes on the screen. The surface of the ball screw enables the screen to move the stones and other construction waste to the top of the repair room when it rises, thereby realizing the separation of the stones and other construction waste, reducing the operation steps of soil repair and reducing the amount of soil cost of repair.

Description

technical field [0001] The invention relates to the technical field of soil ectopic restoration, in particular to an ectopic solidification and stabilization soil restoration equipment and a soil restoration method. Background technique [0002] Soil is the natural base for plant growth and reproduction, the basic production resource of agriculture, and an important natural resource for human survival. Seriously, soil pollution, as a problem that restricts the sustainable development of human society, is attracting more and more attention from countries all over the world. The technology of ex-situ solidification and stabilization of soil remediation refers to adding solidification and stabilizer to polluted soil, so that it can interact with polluted medium and pollutants. Fully mixed, the contaminated soil can be physically sealed into a solid with low permeability with complete structure, or the pollutants can be converted into chemically inactive forms through chemical r...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing devices use contaminated soil to be added to the device, and chemicals are added to the soil in the device to restore the soil. However, in actual use, the soil often contains stones and other construction waste. Existing devices need to use other equipment to remove stones and other construction waste before performing soil remediation when performing soil remediation, which increases the operation steps and increases the cost of soil remediation

[0004] Most of the existing devices need to mix different agents in advance and then add them to the soil, but the mixing ratio of the agents required for soils with different degrees of pollution is also different. The medicine is added and mixed in stages, the operation is complicated, and the labor intensity of the operator is increased.

[0005] Most of the existing devices directly add the medicament to the soil when adding the medicament, but most of the devices cannot control the amount of the medicament added during the process of adding the medicament, and most of the medicament may be added to the soil when adding the medicament The position in the center is at the same point, when the soil and the agent are subsequently mixed, there may be too much or too little agent added, which reduces the working quality of the device
