Description
Technical field
The present invention relates to technical field of soil remediation more particularly to a kind of soil-repairing agent and preparation method thereof.
Background technique
In recent years, as China's economic development and city layout adjust, many chemical fertilizer factories, insecticide factory, chemical plant etc. are a large amount of
The enterprise of discharge organic waste moves away from down town, a large amount of abandoneds occurs, the preceding work left unused or do not used
Industry and commercial land.These lands used are most of due to entering a large amount of chemicals, cause serious pollution to soil.When in soil
It contains hazardous substance excessive, more than the self-purification capacity of soil, composition of the soil, structure and function will be caused to change, micro- life
Object activity is suppressed；Harmful substance in soil by volatilization, underground water, plant absorption and accumulation, and by sky gas and water,
Food chain is enriched in humans and animals body, to endanger human and livestock health, causes the diseases such as cancer.Therefore, according to national related rule
Fixed, these contaminated soils need to carry out environmental assessment and can just put back into after being repaired according to pollution condition.
Contaminated soil remediation makes the reduction of its concentration generally by the pollutant in transfer, absorption, conversion and degradation soil
To acceptable level, or convert poisonous and harmful substance to nontoxic substance.Currently, main restorative procedure includes object
Manage partition method, the dripping method of solution, fixed conversion method, Electrodynamic force method, extraction, oxidizing process, reduction method, soil-repairing agent method and life
Object repairing method etc..But more or less there is the problems such as at high cost, reparation pollution is single, repairing effect is to be improved in these technologies.
