Abstract

The invention discloses a treatment device for heavy metal pollution in soil. The device comprises a platform, and a front roller and a rear roller are rotatably mounted on support legs at the front end and the rear end of the platform respectively; a shovel plate is rotationally installed on the bottom face of the front end of the platform, a liquid storage tank is installed on the upper end faceof the platform, a spraying plate is installed at the bottom of the shovel plate, and a liquid conveying pipe communicates between the spraying plate and the liquid storage tank; and a sleeve is fixed to the bottom face of the rear end of the platform, a telescopic column is movably sleeved with the sleeve, an installation plate is fixed to the bottom of the telescopic column, and a plurality ofrakes are arranged on the installation plate. The surface layer of contaminated soil is shoveled up through the shovel plate, meanwhile, remediation liquid is sprayed to the inner layer of the soil through a spray head, and then the rakes reciprocate up and down, so that the soil layer is continuously punctured, the remediation liquid permeates into the deep part of the soil layer from puncture holes, and the treatment effect is improved; and soil shoveling, pesticide spraying, soil covering and puncturing processes are continuously carried out, so that uninterrupted treatment of soil can be realized, and the treatment efficiency is high.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a device for treating heavy metal pollution in soil. Background technique [0002] Soil heavy metal pollution refers to human activities, the content of trace metal elements in the soil exceeds the background value, and the excessive content caused by excessive deposition is collectively referred to as soil heavy metal pollution. Soil heavy metals refer to the phenomenon that human activities add metals to the soil, causing the heavy metals in the soil to be significantly higher than the original content, and resulting in the deterioration of the quality of the ecological environment. Contaminated soil restoration refers to physical, chemical, biological, ecological principles, and It is a technical measure to reduce the concentration of soil pollutants by adopting artificial control measures, realize the harmlessness and stabilization of pollutants, and achieve the expect...
