Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of soil remediation equipment, and in particular to a soil remediation device for pouring a remediation agent. Background Art
[0002] Contaminated soil is repaired through physical and chemical methods to extract or reduce the pollutants in it, thereby reducing the degree of soil pollution. Among them, the chemical oxidation remediation method uses a remediation agent. The remediation agent produces an oxidation reaction with pollutants in the soil, causing the pollutants in the soil to degrade or convert them into low-toxic, low-mobility products.
[0003] The existing soil remediation device moves on the contaminated soil to pour the remediation agent. The remediation agent penetrates downward from the soil surface. The penetration speed of the remediation agent in the soil is relatively slow. The content of the remediation agent in the lower layer of soil is affected by the density of the soil. The remediation agent in the upper layer of soil is more concentrated, resulting in a large difference in the content of the remediation agent between the upper and lower layers of the soil. The content of the remediation agent in the lower layer of soil is small and the remediation effect is poor. In addition, the slow penetration speed can easily lead to the volatilization and consumption of the remediation agent, resulting in large loss of remediation agent and large usage.
