Background technique

During the production and operation of electroplating plants, chemical plants, oil refineries, pharmaceutical plants, and gas stations, a large amount of organic matter, heavy metals and other wastes will accumulate in the soil of the site, causing serious pollution of the site and soil. The complex composition, strong pollution and high concentration of pollutants in the site are potential pollution sources, and some more toxic intermediate products will be produced in the environment. If they are not treated in time for a long time, they will damage the surrounding soil, surface water and even groundwater. Pollution can also enter the human body through the food chain through drinking water or through the soil-plant system, endangering ecological security and human health. Therefore, the remediation of organic or heavy metal-contaminated soil is imminent.

The technologies currently applied to soil remediation are mainly divided into two categories: ex-situ remediation and in-situ remediation; among them, ex-situ remediation needs to concentrate the polluted soil, and then add various remediation agents according to the type of polluted soil to target specific polluted soil. The soil needs not only leaching and restoration, but also ventilation and oxygen supply to ensure the modification effect. However, the current restoration scheme adopted in the restoration process cannot combine the two well, resulting in a greatly reduced soil restoration effect.

Unicom; the input end of the liquid circulation channel 6 is connected with the soil repair liquid storage tank 20 through the liquid inlet valve 21 and the supercharger 22 in turn; wherein, the bottom of the repair reaction chamber 11 is provided with a liquid outlet, and the drain The liquid port is connected with a leachate collection tank 26 through a drain valve 25 .

Further, the output end of the exhaust fan 10 is connected to an exhaust gas cooling tower 15 , and the output end of the exhaust gas cooling tower 15 is connected to an exhaust gas absorption tower 16 .

Beneficial effects of the utility model: the utility model can fully stir the soil in the soil remediation oxygen supply cavity through the agitating shaft assembly set, firstly carry out the repairing of the soil by spraying mixing and agitating through the remediation liquid, and then by setting The unique air inlet channel can evenly send the air to the front and rear parts of the soil repair oxygen supply chamber, and fully mix with the soil in the stirring, so that the oxygen in the air can fully contact the soil again, and the ventilation effect can be improved. Better, the gas supply efficiency is higher, and finally realizes the secondary restoration of the soil. The set air outlet channel can discharge the waste gas from various parts in the soil repair oxygen supply chamber, which improves the discharge efficiency of the waste gas.
