Heavy metal soil remediation device

Abstract

The invention discloses a heavy metal soil remediation device comprising a base. Supporting legs are arranged at the four corners of the bottom end of the base correspondingly. Driving wheels are arranged at the bottom ends of the supporting legs; an operating room is arranged on the left of the top of the base; two first hydraulic cylinders are arranged on the left side of the bottom end of the base; the bottom end between the two first hydraulic cylinders is rotationally connected with a soil turning roller; soil turning teeth are arranged on the outer side of the soil turning roller; a soilturning motor is arranged at the front end of the first hydraulic cylinder on the front side; the output end of the soil turning motor is connected with the front end of the soil turning roller, twosecond hydraulic cylinders are arranged at the bottom end of the base and located on the right sides of the first hydraulic cylinders, a first rotating shaft is rotatably connected to the bottom end between the two second hydraulic cylinders, and two fixing lugs are arranged at the bottom end of the base and located on the right sides of the second hydraulic cylinders. With application of the heavy metal soil remediation device, remediation liquid can be evenly diluted and evenly sprayed to soil, the contaminated soil remediation quality and efficiency are improved, and waste of the remediation liquid is reduced.

Description

technical field [0001] The invention specifically relates to the technical field of heavy metal soil restoration, in particular to a heavy metal soil restoration device. Background technique [0002] With the development of industry and the modernization of agricultural production, the problem of environmental pollution is becoming more and more serious, among which the problem of soil heavy metal pollution is very prominent. Since Wagner KH and Sid first published literature on soil heavy metal pollution in 1973, it has been more than 30 years of research. Soil is one of the main natural resources that human beings rely on for survival, and it is also an important part of the human ecological environment. However, as an open system, soil is exchanging material and energy with other elements in the environment every moment, and heavy metals enter the soil through atmospheric deposition, sewage irrigation, application of pesticides and fertilizers, and solid waste discharge....

AI Technical Summary

Problems solved by technology

[0003] Heavy metal soil pollution needs to be repaired. The general method is to splash the repair solution on the contaminated soil. When the repair solution is splashed on the surface of the soil, it will be absorbed by the soil. It does not have the effect of repairing, and it also causes a lot of waste of repairing liquid.
