Problems solved by technology

[0004] In view of the above problems, the present invention provides a heavy metal contaminated soil treatment system and process, which obliquely lifts and sprinkles the initially crushed heavy metal contaminated soil to the screening rake with magnetic adsorption, and uses the screening rake to reduce heavy metal pollution. The soil is crushed twice, and the magnetic heavy metals contained in the heavy metal-contaminated soil are sucked out by magnetic adsorption, which solves the screening problem of magnetic heavy metal pollutants in polluted soil and improves the quality and efficiency of heavy metal pollutants in the subsequent treatment process

Abstract

The invention discloses and provides a heavy metal polluted soil treatment system and process, aiming to solve the screening problem of magnetic heavy metal pollutants in polluted soil, which includes a first crushing and screening mechanism, a second crushing and screening mechanism, and a transfer and conveying mechanism And the lifting mechanism, through the oblique lifting and throwing of the heavy metal contaminated soil after the initial crushing to the screening rake with magnetic adsorption, the secondary crushing of the heavy metal contaminated soil is carried out by the screening rake, and the heavy metal contaminated soil is sucked out by magnetic adsorption The magnetic heavy metals contained in it improve the quality and efficiency of heavy metal pollutants in the subsequent treatment process.

Description

technical field [0001] The invention relates to the field of heavy metal-contaminated soil treatment, in particular to a heavy metal-contaminated soil treatment system and process. Background technique [0002] With the rapid development of industry, the problem of soil pollution is becoming more and more serious, and the problem of the treatment of polluted soil is also becoming more and more prominent. In order to reduce the waste of resources, it is very necessary to research and develop new technologies with high efficiency, environmental protection and energy saving for dealing with polluted soil; in the cement industry Among them, after the contaminated soil is treated, it can play an important role in replacing cement raw materials and fuels, thereby turning waste into wealth and saving resources and energy; in cement production, the calcination process is the most important part, but the sludge in sludge Some heavy metals have a serious impact during calcination; the...
