Organic polluted soil and underground water restoring method and agent

Abstract

The invention relates to an organic polluted soil and underground water restoring method. Pollutants of soil and underground water are organic pollutants. The treatment method comprises two parts that (1) the A area is an overlapping polluted area of the soil and the underground water and adopts an in-situ chemical oxidation restoring technology method; and (2) only an underground water polluted area exists in the B area, and a pump-and-treat technology method is adopted. According to the organic polluted soil and underground water restoring method, restoring work of the soil and the underground water in different areas is conducted in a mode that various restoring technologies are combined, thus, it can be guaranteed that the construction period is shortened, and the cost is reduced, while it can be guaranteed that good restoring effects of the soil and the underground water are achieved, cross pollution and agent waste cannot be caused.

Description

Technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for remediation of organic contaminated soil and groundwater and a medicine. Background technique [0002] Organic pollutants in soil and groundwater are mainly benzene, 1,2-dichloroethane, chlorobenzene, 1,4-dichlorobenzene, 1,2-dichlorobenzene, and chloroform. Different remediation techniques are proposed for different pollutants. At present, the most widely used organic contaminated soil remediation technology methods mainly include in-situ / ex-situ chemical oxidation technology, thermal desorption technology, cement kiln co-processing technology, bioremediation technology, soil leaching technology, etc.; more applications of organic contaminated groundwater The repair methods mainly include extraction treatment technology, permeable reaction wall technology, in-situ chemical oxidation technology, monitoring natural attenuation technology, etc. The curren...

AI Technical Summary

Problems solved by technology

If the extraction treatment technology is used in the groundwater remediation process, the groundwater in Area A and Area B must be extracted and repaired before the soil restoration in Area A can be carried out, which will prolong the construction period and increase the cost; if all the in-situ chemical oxidation treatment technology is used, The in-situ chemical oxidation process in area B will cause cross-contamination of the soil in this area, and at the same time, part of the oxidizing agent will react with the organic matter in the soil, resulting in waste of agent
