Embodiment 1

[0044] see figure 1 , a soil remediation method based on organic pollutants, comprising the following steps:

[0045] S1. Excavate pre-buried pits with appropriate spacing on the polluted soil, and embed the repair chamber 1 into the pre-buried pits;

[0046] S2. Tie the pre-processed repair sinker 3 in the repair chamber 1 through the elastic pull wire 2, and place it in the settlement hole below the repair chamber 1;

[0047] S3. The repair sinking ball 3 triggers the repair action, and slowly settles below the soil, and repairs the soil during the settlement process;

[0048] S4. Regularly sample the soil for pollution detection until the concentration of the target pollutant drops below the restoration target value, then the restoration is completed;

[0049] S5. After the repair sinker 3 is consumed, it is recovered in time and reprocessed for reuse until the repair is completed, and the repair chamber 1, the elastic pull wire 2 and the repair sinker 3 are all recycled....

Abstract

The invention discloses a soil remediation method based on organic pollutants and belongs to the technical field of soil remediation. According to the invention, a remediation bin can be innovativelyintroduced to be buried in the contaminated soil; then, repairing sinking balls which are machined in advance are utilized; the elastic pull wire is tied in the remediation bin to autonomously settleto the deep part of soil; the soil is used for extruding a dynamic pressure needle on the repairing sinking ball; moisture in a water loss block is forced to be released through conduction of the force transmission inner net; then, the characteristic that the water decomposition block decomposes a large amount of gas when meeting water is utilized; soil is crushed through gas impact force and vibration of the dynamic pressure needle; the soil caking phenomenon can be improved; and in addition, when the water decomposition blocks are decomposed, heat is generated to cause decomposition of a thermal decomposition ring, oxygen is released, the bioremediation capsules are driven to be discharged into the soil together, the oxygen content of the soil is increased, degrading bacteria in the bioremediation capsules carry out fixed-point remediation, and the remediation effect of the contaminated soil is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, and more specifically, relates to a soil remediation method based on organic pollutants. Background technique [0002] my country's economic development mode is generally extensive, the industrial structure and layout are still not reasonable, the total amount of pollutant discharge is relatively high, and the soil, as the final receptor of most pollutants, has a significant impact on its environmental quality. Due to the wanton discharge of industrial waste and excessive use of pesticides and fertilizers, organic pollutants are widely distributed in the environment and enriched in the soil environment, eventually endangering human health through bioaccumulation. Soil pollution is concealed, hysteresis, cumulative, irreversible, etc., making it difficult or expensive to remediate contaminated soil. [0003] Pollutants in soil come from a wide variety of sources and can be generally divi...
