Example Embodiment
[0049] Embodiment 1: A kind of deep stirring injection repairing method based on in-situ oxidation repairing soil, specifically including:
[0050] S1: Preliminary soil preparation
[0051] S1-1: On-site deep sampling and analysis
[0052] Set up soil sampling holes, conduct sampling and analyze the collected soil samples;
[0053] S1-2: Preparation of oxidizing agents
[0054] According to the analysis results of soil samples, determine the pollution concentration of different areas and depths, and further adjust the amount of oxidizing agents used for soil remediation;
[0055] S1-3: Segmentation of the soil to be rehabilitated
[0056] According to the pollution concentration, a simple segmentation module is set on the area to be repaired, and the area to be repaired is divided into different area modules according to different pollution degrees; then the required oxidizing agent is configured in the corresponding area module;
[0057] S2: Preliminary protection process...
Example Embodiment
[0077] Embodiment 2: a deep stirring injection repairing method based on in-situ oxidation repairing soil, specifically including:
[0078] S1: Preliminary soil preparation
[0079] S1-1: On-site deep sampling and analysis
[0080] Set up soil sampling holes, conduct sampling and analyze the collected soil samples;
[0081] S1-2: Preparation of oxidizing agents
[0082] According to the results of soil sample analysis, the pollution concentration of each depth in different regions is determined, and the added amount of oxidizing agent used for soil remediation is further adjusted; wherein, the oxidizing agent is specifically a mixture of persulfate and transition metal ions;
[0083] S1-3: Segmentation of the soil to be rehabilitated
[0084] According to the pollution concentration, a simple segmentation module is set on the area to be repaired, and the area to be repaired is divided into different area modules according to different pollution degrees; then the required ox...
Example Embodiment
[0106] Example 3: The difference from Example 2 is that the oxidizing agent is specifically a mixture of persulfate and strong alkali.
