A protective shell 3 is provided on the base 1, and a flotation machine 12 and a repair unit 13 are installed inside the shell 3. It is worth mentioning that through holes are provided on both sides of the shell 3 and are respectively provided with an unearthed port 2 and a conveying assembly 16. Among them, the conveying assembly 16 is located on the outside of one of the through holes, and can transport the soil. A crushing assembly 14 is provided at the front end of the conveyor belt, and large particles of soil can be crushed to reduce their size to meet the need for uniform mixing of the agent and the soil in the later stage. The unearthed port 2 corresponds one-to-one to the conveying assembly 16, and is adapted to the bottom of the repair unit 13, so as to facilitate the export of the repaired soil. This device not only has a screening function, but also can conveniently export the treated soil, making the entire repair process more efficient and convenient.

The other end is provided with a liquid outlet pipeline, which extends to the outside of the housing 3, and a liquid outlet 4 is provided at the end of the housing 3. Through such a design, the waste liquid generated during the repair process can be smoothly discharged from the device, which is convenient for subsequent treatment or recycling.

In order to further improve the remediation effect, a gas supply system may be provided on the top of the flotation machine 12. The gas supply system may provide the required gas to the flotation machine 12 through a nozzle or a gas distribution pipeline. These gases may include oxygen, ozone, nitrogen, etc., which are used to enhance the oxidation, degradation or adsorption reaction during the remediation process, thereby more effectively removing pollutants in the soil.

In addition, in order to ensure the stability and export effect of the repair bottom, a vibration or stirring device can also be set at the bottom of the repair unit 13. The device can promote the soil in the repair process to fully mix and contact with the repair agent through vibration or stirring, improve the repair efficiency, and ensure that the quality of the repaired soil meets the requirements. The setting of the vibration or stirring device can be adjusted and optimized according to the specific situation to meet the repair needs of petroleum hydrocarbon composite contaminated soil of different types and properties.

In the above-mentioned use process, petroleum hydrocarbon composite contaminated soil generally enters the skid-mounted remediation device through the conveying assembly 16, and the large pieces of soil are crushed by the crushing and stirring head and conveyed to the flotation machine 12 through the automatic conveyor belt.

The conveying assembly 16 is generally a common conveying device, such as a belt transmission, and is matched with the flotation machine 12, and is generally a "Z-type conveyor belt".

The activation agent is sprayed into the contaminated soil through the pipeline 11, and the petroleum hydrocarbon contaminated soil fully reacts with the activation agent, and the petroleum hydrocarbon in the soil can be desorbed to the soil surface.

The high-concentration liquid petroleum hydrocarbons on the soil surface are centrifuged by the flotation machine and enter the liquid disposal unit 9 through another pipeline 11 (liquid pipeline). The higher the concentration of petroleum hydrocarbons in the contaminated soil, the more liquid petroleum hydrocarbons will be desorbed;

The oxidizing agent is sprayed into the liquid petroleum hydrocarbon through a pipe 10, and the liquid petroleum hydrocarbon fully reacts with the oxidizing agent to completely oxidize the petroleum hydrocarbon. After being monitored by the sewage monitor and meeting the standards, the petroleum hydrocarbon enters the liquid outlet 4 for discharge. If there is a lot of liquid petroleum hydrocarbon, it can be directly recovered by entering the liquid outlet 4 through the liquid pipeline.

A pipe 10 is provided on the top of the liquid handling unit 9 , and the pipe 10 penetrates to the top of the housing 3 .

The top of the filter tank 6 is provided with an outlet port 7, through which the filtered gas is released to the top of the housing 3.

The purpose of setting the above-mentioned filter tank 6 is that the petroleum hydrocarbon composition in the soil is complex, and some components evaporate into the air and then enter the activated carbon adsorption tank (filter tank 6). After being monitored by the atmospheric monitor and meeting the standards, they enter the outlet and are discharged.
