Heavy metal contaminated soil remediation method

Abstract

The invention discloses a heavy metal contaminated soil remediation method. The method comprises the steps that 1, a plurality of detection points are set on heavy metal contaminated soil randomly, wherein the positions and the depth of the detection points are all different; 2, based on the detection points, heavy metal contamination detection is conducted on the soil, and the heavy metal contamination types and degrees are generated; 3, based on the heavy metal contamination type and degree of each detection point, a heavy metal contamination map of the heavy metal contaminated soil is drawn, and in the heavy metal contamination map, the heavy metal contamination type and degree of each coordinate point in the map are shown; 4, based on the heavy metal contamination map, a heavy metal contamination remediation map is generated correspondingly, and based on the heavy metal contamination remediation map, a heavy metal contamination remediation scheme is generated. The technical effectsthat the method is reasonable in design, soil remediation is conducted accurately and efficiently, and the remediation effect is good are achieved.

Description

Technical field [0001] The invention relates to the field of soil remediation, in particular to a method for remediating heavy metal contaminated soil. Background technique [0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce their concentration to an acceptable level, or to convert toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation can include: (1) Changing the form of pollutants in the soil or the way they combine with the soil to reduce their mobility and bioavailability in the environment; 2) Reduce the concentration of harmful substances in the soil. [0003] In the prior art, the prior art mainly uses artificial soil remediation based on the pollution results of a large area of ​​soil, and the soil pollution location is inaccurate, resulting in poor soil remediation effects. Summ...
