Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of soil remediation, in particular to a full-automatic integrated chemical oxidation and solidification and stabilization soil remediation equipment. BACKGROUND

[0002] Soil is the natural base for plant growth and reproduction, the basic production resource of agriculture, and the extremely important natural resource for human survival. With the intensification of industrial and urban pollution and the increase in the types and quantities of agricultural chemicals, soil pollution is becoming increasingly serious. Soil pollution, as a problem restricting the sustainable development of human society, is attracting widespread attention worldwide. Soil pollution has characteristics such as long-term and irreversibility. Harmful substances in soil can accumulate to a certain extent, leading to soil degradation, reduced crop yield and quality, and pollution of surface water and groundwater through runoff and leaching, thereby worsening the hydrological environment. Soil pollution causes secondary pollution to groundwater and surface water, and endangers human health through the food chain via drinking water or the soil-plant system. Therefore, soil remediation devices are needed to remediate soil.

[0003] The existing soil remediation devices all put contaminated soil into a stirring device, then add a chemical oxidant to automatically remediate the soil. However, the existing soil remediation devices have certain drawbacks. For example, after the soil in the stirring barrel is uniformly mixed with the chemical oxidant, the soil in the stirring barrel needs to be completely discharged before the next soil remediation and stirring, and the soil discharge is relatively slow, which can affect the soil remediation efficiency.
