Problems solved by technology

[0003] Most of the existing electrochemical devices for treating heavy metal-contaminated soil use artificial dosing methods when dosing eluents, and the determination of heavy metals in the treated soil requires manual soil determination, which requires a lot of manpower and labor. Material resources will cause unnecessary waste

Abstract

The invention relates to an automatic device for treating heavy metal contaminated soil, and belongs to the technical field of contaminated soil treatment devices. A soil sampling device is arranged,and the automatic sampling process can be completed through a material taking hopper, a conveying chain and a belt conveyor; and a sampling box is provided with a heavy metal detector for detecting indexes of heavy metal ions in the treated soil. After detection is completed, the sampling box opens an electric opening and closing door at the bottom of the sampling box, and soil falls back to a treatment box; and then the sampling box closes the electric opening and closing door at the bottom of the sampling box, so that preparation is made for the next sampling detection. By repeating the process, the soil treatment condition can be monitored in real time. After the soil treatment reaches the standard, a control system can control the contaminated soil treatment device to stop running; then waste liquid is discharged; and finally, the treated soil is collected. By means of an existing conventional computer control program, automation of the contaminated soil process can be achieved.

Description

technical field [0001] The invention relates to an automatic device for processing heavy metal-contaminated soil, and belongs to the technical field of contaminated soil processing devices. Background technique [0002] According to the results of the second national pollution census, my country's soil environmental quality problems cannot be ignored. Statistics show that inorganic pollution accounts for more than 80% of polluted soil, and heavy metal pollution is a major problem. Due to the enrichment and biological toxicity of heavy metal pollutants, they not only cause great harm to the ecological environment and biodiversity, but also accumulate in the soil and be absorbed by plants, thereby accumulating into the human body through the food chain and posing a great threat to human health. The remediation and treatment of heavy metal-contaminated soil has become the focus of increasing attention. [0003] Most of the existing electrochemical devices for treating heavy me...
