In-situ chemical oxidation remediation technology is the addition of oxidizing agents to the site to make on-site pollutants non-toxic or low-toxic substances, thereby achieving the purpose of contaminated soil remediation. Such contaminated soil remediation methods have the advantage of not requiring soil excavation or transportation, being easy to construct, low cost, and having little impact on the surrounding environment.
However, if the contaminants in the soil are deeply hidden, it is difficult to eradicate them effectively even with general chemical remediation methods. Digging up the soil requires a lot of work, and the contaminants in the soil can be removed quickly using chemicals. It's not something that can be done.
Therefore, a device is needed to remove pollutants deep in the soil, and it is necessary to slowly release remediation agents into the soil.
Contaminants in the soil are thoroughly removed using a slow chemical reaction between the remediation agent and the contaminants in the soil.

S2, the compressed air storage tank 122 is filled with air by the air compressor 121, and the pressure inside the compressed air storage tank 122 is brought to 9 standard atmospheric pressure.
S3, the powdered medicine in the medicine tank 11 is transported by the powder conveyor 13 to the powder nozzle 211, and the powdered medicine is sprayed onto the dispersion cartridge 213 using the powder nozzle 211 to be dispersed, the powdered medicine is a repairing medicine; Commercially available potassium permanganate powder is used.
There is a drug capsule 243 in the drug temporary storage cartridge 24, and the inner rod of the puncture telescopic rod 252 extends to move the puncture needle 253 upward, and the puncture needle 253 punctures the medicine capsule 243 from the bottom to the top. In this way, the airflow outlet hole 255 and the airflow introduction hole 256 of the puncture needle 253 are inside the drug capsule 243, the upper end of the puncture needle 253 is inserted into the third communication tube 241, and the lower end of the puncture needle 253 is inserted into the third communication tube 241. The pipe is connected to the compressed air storage tank 122 through the pipe, and has a valve to introduce air to the lower part of the puncture needle 253, and the air inside the puncture needle 253 is discharged from the air flow outlet hole 255 into the inside of the drug capsule 243. The airflow that has entered the inside of the drug capsule 243 carries the drug powder and enters the upper part of the puncture needle 253 through the airflow introduction hole 256, and the airflow carrying the drug powder is discharged from the upper end of the puncture needle 253 and passes through the third communication enters the inside of the drug dispersion device 21 via the pipe 241;

Experimental example We are currently conducting a remediation experiment at a site contaminated with polycyclic aromatic hydrocarbons (PAHs) in our city, using the buried piles of Example 1, and using the in-situ remediation method of contaminated soil of Examples 2, 3, and 4. Comparisons were made with soil remediation at contaminated sites.
The contaminated site was divided into 4 groups with 5 tons of soil to be remediated using barriers, and 80 kg/T of commercially available potassium permanganate powder was used as the powder chemical used in each remediation experiment. The above step S12 is repeated, and the time interval for introducing high pressure air into the drug release outer tube 311 is set to 3 hours, and 1

As can be seen from the results in Table 1 above, the pressure of the compressed air storage tank has an impact on the remediation of polycyclic aromatic hydrocarbon contaminated sites, among which 9 standard atmospheric pressure in Example 2, 10 in Example 4 At standard atmospheric pressure, the treatment effect is better, and as a result of comparing Example 2 and Example 4, there is a small difference in their removal rates. The repair effect is better.
In addition, in order to further verify the effectiveness of using the buried pile of the present invention, a group of control examples was set up for comparison, in which potassium permanganate was evenly spread over the soil area to be repaired. 80 kg/T of commercially available potassium permanganate powder is used as a powder drug. The results after 15 days of treatment are shown in Table 2 below.

As can be seen from the results in Table 2 above, as a result of comparing Example 2 and the control example, when a polycyclic aromatic hydrocarbon contaminated site is repaired by uniformly spreading the chemical, the removal rate is higher than that of the buried pile of the present invention. Therefore, by using the buried pile of the present invention to release powdered chemicals in a controlled manner, it is possible to effectively improve the remediation effect of contaminated soil.
