Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, in particular to an in-situ ecological remediation device for contaminated soil. Background Art

[0002] Environmental pollution has always been a hot topic of concern worldwide and a major challenge facing all of humanity. Soil is the main reservoir for various pollutants in the environment. Strengthening soil pollution prevention and control and improving soil environmental quality are important parts of building an ecological security system and are also a development need for environmental science and technology. Soil ecological restoration devices are needed for soil remediation, such as the patent announcement number CN 113477701. B's patent records an urban soil ecological restoration device, in which the cross-sectional edges of the first guide ring, the second guide ring and the third guide ring are all right-angled triangles, and the right-angled sides are arranged in contact with the inner wall of the restoration tank. The ring diameter of the first guide ring is smaller than the diameter of the umbrella plate, which is conducive to the soil entering the restoration tank and will not remain on the edges of the first guide ring, the second guide ring and the third guide ring. At the same time, the ring diameter of the first guide ring is smaller than the diameter of the umbrella plate, so that when the soil passes through the third guide ring, it can be ensured that the soil is completely covered on the umbrella plate; by providing a spray assembly, when the restoration soil passes through the screen of the feed assembly, the soil is evenly dropped on the umbrella plate by the shaking of the screen. Due to the inclined nozzle, the outer side of the umbrella plate is evenly adhered to the restoration solution, so that when the restoration soil contacts the umbrella plate, it can be evenly contacted with the restoration solution, thereby improving the restoration efficiency.

[0003] However, when the device repairs the soil, the soil to be repaired is first transported to the repair base, the soil is dried and crushed, and then a repair fluid is added to the crushed soil. The soil is repaired by the action of the repair fluid. The soil transportation process makes the repair process more complicated, consumes more resources, and makes the soil repair untimely.

[0004] Based on this, a contaminated soil in-situ ecological restoration device is now provided, which can eliminate the disadvantages of existing devices. Summary of the Invention
