Problems solved by technology

However, this technology is used for reference in contaminated soil remediation projects. On the one hand, it can only be applied to two-dimensional flat areas with small terrain fluctuations and shallow contaminated soil. On the other hand, a large number of multiple samples are required to meet the remediation prescription. Drawing precision

Abstract

The invention relates to the technical field of pollution treatment, and in particular relates to an accurate targeted remediation method and accurate remediation system for polluted soil through soiltesting formulation. The method comprises the following steps: acquiring distribution data of pollutants in different positions of the soil in the polluted area; calculating a three-dimensional depiction of contents of soil pollutants in the polluted area according to the distribution data of the pollutants; calculating an injection position and injection amount of a remediation preparation in the soil in the polluted area according to the three-dimensional depiction of the contents of the soil pollutants in the polluted area; and injecting the remediation preparation into the soil in the polluted area according to the calculated injection position and injection amount. The method provided by the invention accurately determines the amount of the remediation preparation, the injection position of the remediation preparation and the injection frequency according to sampling detection in the polluted area, improves the remediation efficiency, reduces the remediation costs, and reduces secondary pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of pollution control, in particular to a method and system for precise and targeted restoration of polluted soil soil testing formula. Background technique [0002] Chemical remediation of contaminated soil on site is a remediation technology that adds chemical remediation agents to the soil to cause chemical reactions with pollutants, and finally degrades or converts pollutants into products with low bioavailability and low mobility. The in-situ chemical remediation technology does not need to dig out all the contaminated soil, but injects the remediation agent into the soil by arranging drilling wells at different depths in the polluted area, and through the mixing and reaction of the agent and pollutants, the pollutants can be degraded or recovered. The purpose of the shape change. Chemical remediation technology is a soil remediation technology with high response intensity, insensitivity to pollutant co...
