Dynamic control technology for long-acting precise release of in-situ chemical oxidation material

Abstract

The invention relates to a dynamic control technology for long-acting precise release of an in-situ chemical oxidation material, which is used for groundwater remediation and comprises the steps of excavating a remediation well penetrating groundwater pollution plumes; sequentially arranging a plurality of sections of remediation units in the remediation well in a segmented mode, and filling each section of remediation unit with an in-situ chemical oxidation material used for remediating the pollution plume in a sealed mode, wherein each section of remediation unit is provided with a control switch used for controlling release of the in-situ chemical oxidation material; and searching the remediation unit corresponding to the pollution plume, turning on the control switch corresponding to the remediation unit, releasing the in-situ chemical oxidation material, and remediating the pollution plume. The release amount of the in-situ chemical oxidation material can be adjusted, the release of the in-situ chemical oxidation material can be controlled by searching the remediation unit corresponding to the pollution plume, the reaction efficiency of remediation and purification of the pollution plume can be improved, remediation with stable length can be achieved, waste of the in-situ chemical oxidation material can be avoided, and the overall repair cost is reduced.

Description

technical field [0001] The invention relates to the technical field of groundwater restoration and purification, in particular to a dynamic control technology for long-term precise release of in-situ chemical oxidation materials. Background technique [0002] Groundwater is a precious freshwater resource for human beings. However, with the continuous development of social industrialization, wastewater discharge, industrial waste residue, agricultural irrigation, landfill leakage, and damage to transportation pipelines and storage tanks for petrochemical raw materials may cause groundwater pollution. It makes the original tense water shortage problem more serious, and poses serious threats and challenges to human health, food safety, drinking water safety, regional ecological environment, sustainable economic and social development, and even social stability. Groundwater restoration has become a public concern and environmental issues of social concern. [0003] Remediation ...

Problems solved by technology

[0004]In the existing in-situ chemical remediation technology, the groundwater pollution plume is mainly repaired by putting in-situ chemical oxidation materials into the remediation well. However, the groundwater pollution plume There is a change in the concentration of the in-situ chemical oxidation material, and the control of the release amount of the in-situ chemical oxidation material is relatively high. If the release amount is too low, the pollution of the groundwater cannot be effectively repaired. If the release amount is too high, there will be waste of the in-situ chemical oxidation material. , the service life of in-situ chemical oxidation materials is shorter, increasing the overall repair cost
