Problems solved by technology

This technology has the advantages of flexible operation, stable repair effect, short cycle and high efficiency. However, this technology has limited application range, high cost and will cause secondary pollution
[0005] 2 Biological method: the use of microbial degradation to remediate soil pollution is a common remediation technology in daily life. This method has good treatment effect, low treatment cost, and will not cause secondary pollution, but the remediation rate is slow and achieves regulation. Levels take quite a while
Thermal desorption technology has the advantages of wide pollutant treatment range, movable equipment, and reusable soil after restoration. However, the main domestic equipment currently relies on imports, resulting in high equipment investment costs.
[0007] The Chinese utility model patent publication number is: CN202655328U, and the publication date is: 2013-01-09, which discloses an integrated contaminated soil crushing and mixing restoration equipment to solve the problem of insufficient soil crushing and stability during the treatment of heavy metal contaminated soil. Technical problem of uneven mixing of chemicals
[0008] The publication number of the Chinese utility model patent is: CN202877224U, and the publication date is 2013-04-17, which discloses an in-situ restoration equipment for polluted soil integrated with dosing, excavation, crushing and mixing, which has solved the problem of heavy metal and organic matter polluted soil During the treatment process, the soil is not broken enough, the mixing and stirring with the stabilizer is uneven, the medicine cannot be added at the same time of crushing, mixing and stirring, and the technical problems of high cost of ex-situ treatment;
[0009] The equipment provided by the above two patents is suitable for the solidification and stabilization of contaminated soil. The principle is to mix an appropriate amount of heavy metal stabilizer with the contaminated soil, so that the heavy metal in the contaminated soil reacts with the stabilizer to improve the heavy metal pollution. The stability of the substance reduces its water solubility, diffusibility and bioavailability, thereby reducing its harm. However, the solidified heavy metals are easy to reactivate when the environmental conditions change, and pollutants such as heavy metals and pesticides may cause soil pollution again. Pollution

Abstract

The invention relates to an automation system for removing soil pollutants, and belongs to the field of environmental protection machinery. The automation system comprises a soil stirring device, wherein a feed port and a discharge port are formed in the soil stirring device; an absorbent feeding hopper is arranged above the feed port; a conveyer is arranged below the discharge port; a magnetic separation device is arranged on the conveyer; a soil liquefying device is arranged below the tail end of the conveyer; and the soil liquefying device is connected with soil repairing equipment through a pipe. The automation system for removing soil pollutants has such advantages as high automation degree and excellent treatment effect.

Description

technical field [0001] The invention relates to an automatic system for removing soil pollutants, belonging to the field of environmental protection. Background technique [0002] In the past 20 years, with the continuous deepening of industrialization, urbanization, and rural intensification in my country, the problem of soil pollution has increased day by day. The worsening of soil pollution and the non-renewable characteristics of soil have become a major problem restricting the continued development of our country. Solving the problem of soil pollution has become an urgent need for our country to achieve sustainable development. [0003] The current common treatment methods for soil pollution are as follows: [0004] 1 Chemical leaching method: the process of injecting a leaching agent into contaminated soil or sediments to elute and clean pollutants in the soil. This technology has the advantages of flexible operation, stable repair effect, short cycle and high effici...
