Description
Technical field
The present invention relates to a kind of mercury contaminated soil renovation agent and preparation method thereof, belong to technical field of soil remediation.
Background technology
Heavy metal pollution of soil refers to that due to mankind's activity content of the minor metallic element in soil in soil exceedes
Background value, too high levels caused by excess deposition, is referred to as heavy metal pollution of soil.And farmland soil heavy metals pollution have it is huge
Big harmfulness, heavy metal in soil pollution can not only cause crop production reduction and quality decline, can also pass through soil-plant
System, enters people's human body through food chain, is detrimental to health and life security.Heavy metal pollution of soil has the hysteresis of disguised harm
Property, chronicity and biological chain heavy metal biological concentration the features such as, heavy metal pollution of soil is recognized if these decide
The serious consequence for being difficult to expect will be brought with hysteresis is administered.
The bio-toxicity of mercury (Hg) is more significant, and its heavy metal ion will produce when mass concentration is 0.01-0.001mg/L
Toxigenicity.Mercury in soil can be divided into mercury metal, inorganic reference state mercury and organically combine state mercury by chemical form.Inorganic mercury enters
Mercuric salt is converted into after human body.Cell eubolism is destroyed, influences function of human body；Organic mercury in soil can not only pass through
Microbial degradation reduces its toxicity, can be converted into the bigger methyl mercury of toxicity by methylation on the contrary, biology is caused
Bigger injury.
In consideration of it, it is necessary to research and develop a kind of mercury contaminated soil renovation agent and preparation method thereof, to solve the above problems.
