Soil treatment and remediation device

Abstract

The invention relates to territorial resource treatment, and concretely relates to a soil treatment and remediation device capable of improving soil remediation and improvement efficiency. An excavating device comprises an excavating bucket arranged at the left end of the bottom of the rack, the excavating bucket comprises a bottom plate, vertical plates are arranged at the front end and the rearend of the bottom plate, and excavating teeth are arranged at the left end of the bottom plate; and one ends of first connecting rods are hinged to a rack, the other ends of the first connecting rodsare hinged to the left parts of the vertical plates, one ends of transmission connecting rods are in transmission with a power device, and the other ends of the transmission connecting rods are hingedto the right parts of the vertical plates. The rack, rolling wheels, the power device, an excavating device and a soil improvement and remediation liquid spraying device are matched to make the soilimprovement and remediation liquid spraying device continuously spray, a soil improvement and remediation liquid medicine is sprayed to soil before excavation, and after the power device drives the excavating device to excavate the soil, the soil improvement and remediation liquid spraying device continues to spray the excavated soil, and the amount of soil absorbing the soil improvement and remediation liquid can be increased, so the soil remediation and improvement efficiency is greatly improved.

Description

technical field [0001] The invention relates to land resources management, in particular to a soil treatment and restoration device capable of improving the efficiency of soil restoration and improvement. Background technique [0002] Soil pollution in China has threatened the sustainable use of land resources and the ecological security of agricultural products. The farmland polluted by organic pollutants in the country has reached 36 million hectares. The types of pollutants include petroleum, polycyclic aromatic hydrocarbons, pesticides, and organic chlorine. It also pollutes a large area of ​​land; in the Shenfu petroleum sewage irrigation area, the content of polycyclic aromatic hydrocarbons in the surface layer and bottom soil both exceeds 600mg / kg, causing serious pollution of crops and groundwater. There are 20 million hectares of land polluted by heavy metals across the country, of which more than 700,000 hectares are seriously polluted, and 130,000 hectares of whi...

AI Technical Summary

Problems solved by technology

At present, the first method is mostly used. By matching the corresponding soil improvement and restoration solution, the existing form of pollutants in the soil or the combination with the soil can be changed. It is possible to dig a hole and inject the soil improvement and restoration solution to allow it to diffuse. Kailai governance, but this method is slow and inefficient

It can be sprayed directly on the soil surface. This method is also slow and inefficient. In rainy weather, the soil improvement and restoration solution will be washed away directly, and the treatment efficiency is low.
