Abstract
The invention discloses a soil and underground water heavy metal mineral absorbing and enduring material. The soil and underground water heavy metal mineral absorbing and enduring material comprises the following components by weight percent: 45-53% of zeolite powder, 35-45% of bentonite, 10-15% of pulverized coal ash and 1-5% of metal oxide. Compared with the prior art, the soil and underground water heavy metal mineral absorbing and enduring material has the following advantages: based on the prior art, minerals existing in the natural world are screened and modified, and pollutants in soil and underground water are absorbed and endured for a long time so as to achieve the aim of removing pollution; meanwhile, because the adopted minerals exist naturally, an raw materials are easily available, so that secondary pollution is prevented.
Description
Technical field
The present invention relates to sticking material, relate in particular to a kind of soil and underground water heavy metallic mineral sticking material.
Background technology
The soil of China and groundwater pollutant are mainly heavy metal and organic matter, as As, Cd, Cr, Hg, Pb, VOCs, SVOCs, POPs etc., have the features such as wide, the difficult identification of pollution range, difficult, easy migration.At present, domestic adopted method can be divided into Physical, chemical method and bioanalysis.Wherein, chemical method is that chemical agent is added in soil and underground water, by the processing of the principles of chemistry such as curing/stabilizing or oxidation/reduction, can remove to a certain extent pollutant, but because chemicals itself has certain toxicity, very easily cause secondary pollution, and cost and carrying capacity of environment all higher.
Summary of the invention
The present invention is in order to solve above-mentioned deficiency, and a kind of soil and underground water heavy metallic mineral sticking material are provided.
Above-mentioned purpose of the present invention realizes by following technical scheme: a kind of soil and underground water heavy metallic mineral sticking material, by weight percentage, composed of the following components: zeolite powder 45-53%: bentonite 35-45%: flyash 10-15%: metal oxide 1-5%.
Soil of the present invention and underground water heavy metallic mineral sticking material mainly adopt the mode of roasting, remove moisture and impurity in mineral, and expand mineral aperture, improve the ability of surperficial sticking and ion-exchange.
The present invention's advantage is compared with prior art: on prior art of the present invention basis, according to the principle of Environmental Chemistry and Green Chemistry, screen and improve the mineral that occurring in nature itself exists, the pollutant in soil and underground water is carried out to permanent sticking, reach and remove the object of polluting; Because adopted mineral are naturally occurring, raw material is obtained easily, avoids producing secondary pollution simultaneously.
Be specially:
1, cost-saving: raw material are the common natural minerals of occurring in nature.
2, avoid secondary pollution: only have the chemicals of little amount to add.
3, easy construction: only need to carry out proportioning according to the actual conditions of soil and underground water pollution, contact on request with soil or underground water.
4, of many uses: to can be used for soil and underground water, arable land, household refuse landfill sites, wastewater treatment etc.
The specific embodiment
Below in conjunction with embodiment, the invention will be further described.
Embodiment 1: a kind of soil and underground water heavy metallic mineral sticking material, by weight percentage, composed of the following components: zeolite powder 45%: bentonite 35%: flyash 15%: metal oxide 5%.
Embodiment 2: a kind of soil and underground water heavy metallic mineral sticking material, by weight percentage, composed of the following components: zeolite powder 50%: bentonite 37%: flyash 10%: metal oxide 3%.
Embodiment 3: a kind of soil and underground water heavy metallic mineral sticking material, by weight percentage, composed of the following components: zeolite powder 53%: bentonite 35%: flyash 10%: metal oxide 2%.
The present invention has utilized the principle of surperficial sticking, ion-exchange and dissolution precipitation, specifically: 1. surperficial sticking.The natural minerals screening has the larger feature such as specific area, porous, and effectively sticking heavy metal reaches and from soil and underground water, removes the object of polluting.2. ion-exchange.There are the functional groups such as abundant carboxyl, silanol base, aluminol group on the natural minerals surface adopting, has very high ion-exchange capacity, can with soil and underground water in heavy metal ion exchange, reach and remove the object of polluting.3. dissolution precipitation.According to different pollutional conditions, in sticking material, add metal oxide, react with the heavy metal in soil/underground water, can generate water-soluble reactant or indissoluble thing, be convenient to subsequent treatment.
Finally it should be noted that: above-described embodiment is only for example of the present invention is clearly described; and the not restriction to embodiment; for those of ordinary skill in the field; can also make other changes in different forms on the basis of the above description; here without also giving exhaustive to all embodiments; and apparent variation or the variation of being amplified out thus, still among protection scope of the present invention.
