Contaminated soil remediation device

Abstract

The invention discloses a contaminated soil remediation device. The device comprises a machine body, and a driving motor is fixedly accommodated in the machine body; threaded shafts are dynamically mounted at the left and right ends of the driving motor; grooves are formed in the left and right ends of the machine body; the end, away from the driving motor, of the threaded shaft extends into the grooves and is provided with a mounting rod in a threaded mode. A spraying device is arranged in the machine body; soil is stirred and overturned through the rotating soil overturning plate; in the overturning process, chemical agents capable of increasing soil remediation and regeneration can be uniformly sprayed into the soil through the spraying device; the sprayed soil covers the ground again,the width of the soil turning plate can be increased through the extension plate in the width adjusting device according to the fineness required by soil turning, so that the width of single-time soilturning is increased, the soil turning efficiency is improved, and the smaller the total width of the extension plate and the soil turning plate is, the larger the fineness of soil treatment is.

Description

technical field [0001] The invention relates to the technical field of soil regeneration, in particular to a contaminated soil remediation device. Background technique [0002] With the continuous acceleration of the industrialization process, the unreasonable mining of mineral resources, the discharge of machine smelting, the long-term irrigation of sewage and sludge application to the soil, the atmospheric deposition caused by human activities, and the application of chemical fertilizers and pesticides have caused serious soil pollution. At the same time, it will enter the human body through the food chain and cause harm to human health. Therefore, the restoration and regeneration of the soil is particularly important. The existing restoration is divided into physical restoration, chemical restoration, and biological restoration. Among them, chemical restoration will have restoration and regeneration. The chemical agent is sprayed on the soil, and the soil gradually recove...

[0002] With the continuous acceleration of the industrialization process, the unreasonable mining of mineral resources, the discharge of machine smelting, the long-term irrigation of sewage and sludge application to the soil, the atmospheric deposition caused by human activities, and the application of chemical fertilizers and pesticides have caused serious soil pollution. At the same time, it will enter the human body through the food chain and cause harm to human health. Therefore, the restoration and regeneration of the soil is particularly important. The existing restoration is divided into physical restoration, chemical restoration, and biological restoration. Among them, chemical restoration will have restoration and regeneration. The chemical agent is sprayed on the soil, and the soil gradually recovers its normal function after being absorbed, but the direct spraying makes the surface soil absorb, and the internal soil cannot absorb, resulting in its inhomogeneity
