Embodiment 1

[0044] A chemical injection process for in-situ remediation of organic pollution, including the following steps:

[0045]A. Select the plot to be processed, mark the location of the injection hole and drill the hole, and set the offset between two adjacent rows of injection holes;

[0046] B. Put the drug injection pipe into the injection hole to form a drug injection well, the depth of the drug injection well is 2m, and then clean the inside of the drug injection well;

[0047] C. Send the injection head into the drug injection well, and then inject the repair agent into the drug injection well. The injection rate is 5L / min, the injection pressure is 0.5MPa, and when the liquid level of the drug liquid is 0.1cm away from the wellhead of the drug injection well, stop the drug injection , and take out the injection head;

[0048] D. Seal the wellhead of the drug injection well. The sealing material is cement bentonite mixed slurry, and then operate and seal the next drug injec...

Abstract

The invention discloses a medicament injection process for in-situ restoration of organic matter pollution, which includes the steps of drilling, loading a drug injection tube, cleaning the drug injection well, injecting the drug, and sealing; the process of the invention is beneficial to the dispersion and diffusion of the repair agent Great advantages, good soil remediation effect, especially suitable for benzene, benzo(a)pyrene and other organic pollution in the deep soil. The invention also discloses a device for the drug injection process used for in-situ repair of organic pollution, including an injection platform and a cleaning platform; the device of the invention integrates automatic cleaning of drug injection wells and drug injection functions, and has the advantage of convenient operation; The cleaning process is controlled by the hoist and the chain carriage is lowered into the drug injection well. The chain carriage is composed of a chain structure composed of multiple sections. The function is beneficial to the high-pressure rotating water spray head and the water pump head to rise and fall continuously during the working process, and the pumping operation can be performed after water spray cleaning.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a medicament injection process and device for in-situ remediation of organic matter pollution. Background technique [0002] Organic pollutants in soil are a large category of pollutants. Although organic pollutants are not as serious as heavy metal pollutants, their impact on agricultural products and human health has been highlighted. At the same time, with the acceleration of urbanization and industrialization, soil organic pollution near cities and industrial areas has become increasingly serious. Among organic pollutants, diseases and environmental hazards caused by benzene series pollutants are not uncommon. In the prior art, some soil remediation of benzene series pollutants is carried out by mixing and applying soil remediation agents, but there is a problem of poor remediation effect. Therefore, it is very necessary to develop a chemical injection ...
