Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to an environment-friendly soil restoration agent. Background technique [0002] Soil heavy metal pollution refers to the phenomenon that due to the addition of heavy metals into the soil due to human activities, the content of heavy metals in the soil is significantly higher than its natural background content, resulting in ecological damage and deterioration of environmental quality. At present, the treatment methods for heavy metal-contaminated soil mainly include engineering measures, chemical improvement, agronomic measures and biological remediation, but many treatment methods require the use of organic remediation agents to improve the remediation effect. Soil heavy metal pollution is concealed, long-term and irreversible. Pollutants stay in the soil for a long time and cannot be degraded by plants or microorganisms. Heavy metal pollution not only leads to soil degra...
