Description

Technical Field

[0001] The utility model relates to the technical field of soil pollution control, and more specifically, to a spraying device for soil pollution control. Background Art

[0002] Soil, a loose layer of material on the Earth's surface, is composed of various particulate minerals, organic matter, water, air, and microorganisms. It is the foundation of human survival and agricultural production. However, with the acceleration of industrialization and the increase in agricultural activities, soil pollution is becoming increasingly serious. The main sources of pollution include irrational mining of mineral resources and their smelting emissions, long-term sewage irrigation and sludge application, atmospheric deposition, and excessive use of fertilizers and pesticides. These pollution sources lead to the accumulation of heavy metals, organic pollutants, and other harmful substances in the soil, directly threatening the yield and quality of crops, and in turn affecting human health and ecological safety.

[0003] Traditional methods for soil pollution control mainly include physical remediation, chemical remediation, and biological remediation. These methods can alleviate soil pollution to a certain extent, but they have many limitations. For example, physical remediation methods (such as soil replacement) are costly and require a large amount of work; chemical remediation methods (such as leaching) may introduce new pollutants and have a certain impact on soil structure; biological remediation methods (such as phytoremediation) are environmentally friendly, but have long cycles and unstable effects. Spraying devices, as an important tool for soil pollution control, have the advantages of simple operation, wide applicability, and rapid effectiveness. Through the spraying device, soil remediation agents, improvers, or specific chemical agents can be evenly sprayed into the contaminated soil, thereby accelerating the decomposition, transformation, or fixation of pollutants, achieving the purpose of soil pollution control.

[0004] Although spraying devices play an important role in soil pollution control, existing spraying devices still have some shortcomings. For example, when spraying, if it only acts on the soil surface, the amount of the agent itself penetrates is small, and the spraying effect on soil pollution control is not ideal.
