Description
Technical field
The present invention relates to environmental protection technical fields, specifically, the present invention relates to a kind of refuse landfill bentonites
Base inorganic agent and preparation method thereof.
Background technique
Existing refuse landfill is to concentrate to stack place, garbage sanitary filling field using the rubbish under sanitary landfills mode
Because the country is widely used at low cost, sanitation degree fortunately, refuse landfill generally using layering earthing landfill by the way of pair
Rubbish is handled, and is covered one layer of loess again after accumulating one layer of rubbish, is easily reduced the pollution of rubbish in this way.
Bentonite is the nonmetallic minerals using montmorillonite as main mineral constituent, and smectite structure is by two silicon oxygen four sides
Body presss from both sides the 2:1 type crystal structure of one layer of alumina octahedral composition, and there are certain sun for the layer structure formed due to montmorillonite structure cell
Ion, such as Cu, Mg, Na, K, and these cations are very unstable with the effect of montmorillonite structure cell, easily handed over by other cations
It changes, therefore there is preferable ion exchangeable.
Main component montmorillonite in bentonite is natural layered silicate nano material, and particle is tiny, and specific surface area is huge
Greatly；It is negatively charged between montmorillonite layer, make montmorillonite that there is powerful Electrostatic Absorption ability.
The Layered-space structure that montmorillonite has determine its with strong water absorbing capacity, maximum water absorption can reach its from
8-15 times of body weight.
Therefore using bentonite as coating in refuse landfill, can use bentonitic water imbibition, adsorptivity, from
Sub- exchangeability adsorbs sewage, poisonous and hazardous gas and the heavy metal ion etc. in rubbish, and make in rubbish toxic has
Evil object is fixed by bentonite, will not be caused damages to environment, to achieve the effect that high-efficiency environment friendly.
The absorption property of natural montmorillonite is limited, and the pollutant kind in rubbish is various, existing organic pollutant, also has
Inorganic pollution and heavy metal pollution.It further include the microbial contaminations such as germ bacterium, so in order to play bentonitic powerful property
Can, it needs to carry out proper treatment to bentonite, to meet above-mentioned requirements.
Summary of the invention
