Problems solved by technology

However, there are the following problems: the current restoration of soil heavy metal pollution on the market does not consider the impact of the surface energy of different particle sizes of the soil on the restoration effect; the restoration liquid on the market is a pre-configured ratio and type, which cannot be adapted to local conditions, and the restoration effect is poor; Intelligent repair cannot be realized, with low operating efficiency and high labor costs; most of the contaminated sample collection devices and repair devices are two separate devices, and real-time repair cannot be realized when samples are collected; and it is not mobile, or the range of movement is limited Due to the limitation, the sampling location and range cannot be conveniently selected according to the actual topography and landform, which seriously affects the remediation efficiency of heavy metal-contaminated soil.

Abstract

The invention relates to an intelligent soil heavy metal pollution remediation device which is characterized in that through a sampling device, a remediation device and a mixing device, obtained sample soil is graded through various stages of vibrating screens which are arranged on the remediation device and are divided according to the size of soil particles; detection devices are installed in all stages of screening chambers, remediation is conducted according to the pollution conditions of soil of different particle sizes, and the remediation accuracy is high; a heating device is arranged in each stage of screening chamber, so that the repairing chemical reaction is greatly accelerated; under the control of a computer, blending and preparing the remediation liquid according to the type of the remediation liquid required by soil remediation, conveying to a titration device, and stirring and fully mixing; and a carrying vehicle is provided with an adjustor for automatically adjusting the lifting of wheels according to the terrain and a clamping and supporting device, so that the stability of the intelligent soil heavy metal pollution remediation device in the working and transporting process can be ensured, the remediation pertinence is high, the remediation effect is good, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of soil pollution remediation, in particular to an intelligent soil heavy metal pollution remediation device. Background technique [0002] Soil heavy metal pollution has been listed as one of the major environmental hazards in the world. Although relevant departments have introduced control policies in recent years, and enterprises have also stepped up pollution prevention and control efforts in production, the overall situation is not optimistic due to technical limitations. Soil heavy metal pollutants mainly come from industrial and mining activities such as non-ferrous-ferrous metal smelting, production process of heavily polluting enterprises, and agricultural production activities such as sewage irrigation, livestock and poultry breeding, and sludge application. Heavy metals in the soil will indirectly enter the human body through the "soil-plant-human" food chain. They are difficult to metabolize and ...
