An in-situ chemical oxidation repair monitoring and regulation system

Abstract

The invention provides an in-situ chemical oxidation repair monitoring and control system, which belongs to the technical field of pollution control. In the process of in-situ chemical oxidation modification, the present invention comprehensively monitors various geochemical parameters in soil, groundwater and soil gas, and further sets the normal change interval and range of data in the restoration process according to the results of the previous small test or pilot test. The data in the restoration effect reaches the expected inflection point, and the actual monitoring data is judged. If the monitoring data exceeds the normal range, an alarm will be issued and an adjustment suggestion for the injection of the agent will be given. After the adjustment suggestion is confirmed on site, the on-site repair agent injection system will be dynamically adjusted. The present invention realizes the comprehensive monitoring of parameters, and judges the final restoration effect, timely feeds back accurate adjustment suggestion signals to the in-situ injection control terminal, and adjusts parameters such as the injection mode or injection rate of the chemical restoration agent. The invention realizes the goal of in-situ chemical oxidation precise repair.

Description

technical field [0001] The invention relates to the technical field of pollution control, in particular to an in-situ chemical oxidation repair monitoring and control system. Background technique [0002] With the continuous improvement of industrial modernization, the degree of soil and groundwater pollution is becoming more and more serious, because the damage caused by soil and groundwater pollution to people is also increasing. Therefore, in addition to enhancing environmental awareness, reducing the discharge of harmful substances In addition, the remediation of contaminated soil and groundwater is also crucial. [0003] In-situ chemical oxidation remediation is a commonly used soil and groundwater pollution remediation technology, which is to use chemical oxidation reaction to repair the soil or groundwater in its original position, and use oxidants to help reduce the toxicity of harmful pollutants in soil or groundwater, because It is more convenient to carry out res...

AI Technical Summary

Problems solved by technology

[0007] 1. All monitoring results need to be analyzed and judged manually. No matter whether the data is normal or not, manual analysis and judgment are required, which brings a lot of unnecessary operations, and manual adjustments are made according to the judgment results, and the monitoring and control cannot be completed automatically

[0008] 2. The monitoring data is discrete, causing the field engineers to spend a lot of time on data collection and data processing

[0009] 3. The monitoring parameters are few and incomplete, and it is difficult to effectively realize the accurate judgment of the effect of the in-situ restoration process

[0010] 4. The monitoring results are not compared with the normal range of prior experience, and the monitoring results are directly used as the next step, resulting in inaccurate adjustments to the injection volume based on the monitoring results
