In-situ chemical oxidation remediation monitoring and regulating system

Abstract

The invention provides an in-situ chemical oxidation remediation monitoring and regulating system, and belongs to the technical field of pollution treatment. According to the invention, in an in-situchemical oxidation modification process, various geochemical parameters in soil, underground water and soil gas are comprehensively monitored; According to a result of an early-stage small test or pilot test, a data normal change interval in the repairing process and a data standard reaching expected inflection point in the repairing effect are further set, the actual monitoring data is judged, ifthe monitoring data exceeds a normal range, an alarm is given and an adjustment suggestion of medicament injection is given; and an on-site repairing medicament injection system is dynamically adjusted after the adjustment suggestion is confirmed on site. According to the invention, comprehensive parameter monitoring is realized, the final repair effect is judged, an accurate adjustment suggestion signal is timely fed back to the in-situ injection control end, and parameters such as the injection mode or the injection rate of the chemical repair agent are adjusted. According to the method, the purpose of in-situ chemical oxidation accurate repair is achieved.

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
