Abstract

The invention belongs to the field of soil remediation, and discloses a soil remediation agent for reducing high-concentration cobalt and lead pollution and an application of the soil remediation agent. The soil remediation agent comprises the following components in parts by weight: 5-13 parts of sodium cetyl benzene sulfonate, 4-11 parts of calcite in powder, 7-15 parts of tartaric acid, 3-10 parts of acetylacetone, 6-11 parts of calcium chloride and 4-9 parts of sodium pyrophosphate. The application of remediating the soil by the soil remediation agent comprises the steps of crushing, mixing, spraying, plowing and the like, thus the pollution degrees of cobalt and lead in the soil can be effectively lowered.

Description

technical field [0001] The invention belongs to the field of soil remediation, and relates to a soil remediation agent and a preparation method thereof, in particular to a soil remediation agent for reducing chromium, zinc and copper pollution and a preparation method thereof. Background technique [0002] Under natural conditions, heavy metals in soil mainly come from parent rock and residual biological matter, and the content is generally low, which will not cause harm to human body and ecosystem. Anthropogenic action is an important reason for soil to be polluted by heavy metals. During the development of metal deposits, urbanization, solid waste accumulation, and the application of chemical fertilizers, pesticides, sludge, and sewage irrigation to improve agricultural production, heavy metals can accumulate in soil in large quantities. Heavy metals accumulated in the soil can enter water bodies through leaching, and can also enter crops through agricultural activities s...
