Description
Technical field
The present invention is a kind of heavy metal stabilizer, belongs to heavy metal pollution of soil Treatment process field.
Background technology
Heavy metal generally has acute or chronic toxicity, poisons human body in a more complicated manner sometimes, such as carcinogenic or non-
Directly trigger some diseases.In all kinds of hazardous wastes, heavy metal waste occupies very big proportion.They are with various
Mode harmful to human and other organisms.Particularly in security landfill disposal process, because the non-biodegradable of heavy metal is determined
It has been determined by long-term existence in landfill yard, to the great potential threat of environment structure around landfill yard.Soil or irrigation water
In heavy metal can have a negative impact to plant growth, and will plant leaf, stem or root be enriched with so that its influence ripple
And whole food chain.
As caused by mercury pollution " minamata disease " and as caused by cadmium pollution " Itai-itai diseases " in Japan occurs since last century
Event, and Europe some country successively find heavy metal pollutions caused by serious consequence so that on heavy metal pollution with
The research of preventing and treating is by attention.Heavy metal waste wide material sources, it is related to mine, metallurgy, machine-building, chemical industry, electronics and instrument
Etc. industry.On the other hand, with the further investigation of heavy metal toxicology and the development of detection technique, the processing of heavy metal waste
Disposal standard also gradually tends to strict.This point is embodied in needs the other increase of heavy metal classes that monitors, and required reaches
The reduction of heavy metals emission or leaching concentration.On the processing of heavy metal waste, in addition to a portion recoverable, its
Remaining major part all needs to carry out stabilization processes, to reach innoxious purpose.Therefore, the heavy metal of research efficiently, economic is stable
Change technology is for protection human health and maintains the ecological balance significant.
At present, the stabilization technology both at home and abroad to heavy metal in soil is mainly to utilize stabilizer and the heavy metal in soil
Generation chemical physical action, change the chemical form of heavy metal in soil, reduce its migration and reduce the process of its toxicity.
It is used to handle answering for heavy metal pollution of soil in the existing many special chelating type organic heavy metal stabilizers of the developed countries such as America and Europe
Use example.And patent report of the China in terms of heavy-metal contaminated soil stabilizes reparation is less, and focus primarily upon use
In terms of the technical study of the low technical content such as cement, lime, gypsum.And this suction-operated pair by being formed after hydration reaction
The stable fixed effect of heavy metal in soil is easily influenceed by external environmental condition, when soil is invaded by weathering and acid rain for a long time
Erosion, heavy metal therein are faced with the potential danger of dissolution again.Therefore, novel heavy metal stabilizer is developed and its in heavy metal
Application in pollution control will have wide market and practical value in China.
