Description
Technical Field

[0002] Due to human activities, heavy metals that do not exist in the soil are introduced, resulting in their content being significantly higher than the background value, exceeding the soil's own repair capacity, thus posing a serious threat to the ecological environment and human health. Heavy metals can be transmitted through the food chain and cause harm to human health. Heavy metals are difficult to be naturally degraded. Long-term accumulation will lead to a decline in soil fertility, affect the activity of soil microorganisms, destroy the soil ecological balance, and can enter the human body through the food chain, posing a long-term threat to human health.

Since the connection positions of the short columns 209 at both ends of the long column 207 are different, the connecting frame 206 on the outer wall of the long column 207 begins to stir as the stirring inner ring 210 rotates. At the same time, the stirring outer ring 204 outside the stirring inner ring 210 will also begin to rotate with the stirring inner ring 210 to optimize the stirring effect. The repair fluid is usually composed of a variety of chemical substances. Stirring can make the various components evenly distributed in the repair fluid. At the same time, some components in the repair fluid may precipitate over time. Stirring can prevent the formation of precipitation, maintain the stability of the repair fluid, and enhance the physical adsorption effect.
