Description

3-Dimensional imaging system for chemical treatment of polluted soil Technical Field The invention relates to the technical field of polluted soil chemical treatment, in particular to a 3-dimensional imaging system for polluted soil chemical treatment. Background The chemical remediation technology of soil pollution has the following steps: 1. soil performance improvement technology The principle of this technique is to transform contaminants into poorly mobile, low active substances or to remove them from the soil. Soil performance can be improved by both applying a conditioner and altering the Eh of the soil. The technology is mainly aimed at passivation of heavy metals, which is also called heavy metals, and is very effective in application to lightly polluted soil. The soil improvement technology is an in-situ repair technology, does not need to build complex engineering equipment in situ, and is an economic and effective repair technology. In general, in the soil with a low pollution level, a lime material, an organic material, a clay mineral, an ion antagonist, and other modifiers may be added to the soil to improve the performance of the soil and repair the soil polluted by heavy metals, depending on the presence characteristics of the pollutants in the soil. Migration behavior of heavy metals in soil is closely related to oxidation-reduction potential (Eh) of soil. Under the reducing condition, various heavy metal elements in the general soil are combined with the produced H 2 S to form insoluble sulfide precipitates along with the prolongation of flooding time, so that the method of flooding cultivation, applying substances for promoting reduction and providing sources of H 2 S into water can be adopted, the activity of heavy metals is reduced, and the toxic action of the heavy metals is reduced. The EnvirobondTM technology was developed by a company in the united states based on laboratory studies and was applied to two sites contaminated with lead in russia Rosebille with removal rates greater than 99%. 2. Chemical oxidation-reduction repair technology and reduction dechlorination technology Chemical oxidation remediation is a soil in-situ remediation technology which is to set brick wells with different depths in a pollution area, then inject chemical oxidant into soil through pumps in the brick wells, so that the oxidant and the pollutant generate oxidation reaction, and the pollutant is degraded or converted into low-toxicity and low-mobility products. The commonly used oxidants include H2O2, K2MnO4 and gaseous Q3, and the repair technology generally comprises three parts of an injection well, an extraction well, an oxidant and the like. The technology is mainly used for repairing the soil polluted by long-term and difficultly biodegradable pollutants in the soil, such as oils, organic solvents, polycyclic aromatic hydrocarbons, PCP, pesticides, non-water-soluble chlorides (such as trichloroethylene and TCE) and the like. The principle of chemical reduction repair and reduction dechlorination repair is the same as that of chemical oxidation repair, and representative reducing agents mainly comprise liquid SO2, gaseous H2S and zero-valent Fe colloid. There have been many successful cases of this type of repair technology, which is both time-saving and economical. 3. Chemical leaching repair technology The chemical leaching operating system is equipped with three components: 1. A device for applying a leaching solution to the soil; 2. a lower layer leachate collection system; 3. A shower liquid treatment system. The technology is that a hydraulic pressure head is used for pushing cleaning liquid to pass through polluted soil so as to clean pollutants out of the soil, and then the cleaning liquid containing the pollutants is separated. The cleaning liquid can be chemical reagent or clean water. The technology has lower operation cost, and operators do not directly contact pollutants. But is only suitable for soil with large permeability coefficient such as sandy soil, and the introduced cleaning agent is easy to cause secondary pollution. The technology has wide application range, and comprises heavy metals, aromatic hydrocarbons, petroleum, halogenated agents, polychlorinated biphenyl, chlorophenol, pesticides and other pollutants. GIS (geographic information system ) is a discipline that has evolved with the development of geographic science, computer technology, remote sensing technology, and information science. Under the support of computer software and hardware systems, the technical system for collecting, storing, managing, operating, analyzing, displaying and describing the related geographic distribution data in the whole or part of the earth surface (including the atmosphere) space is provided.
