| titleOfInvention | The preparation method of heavy-metal contaminated soil improvement modified mineral composition |
| abstract | The present invention relates to a kind of heavy-metal contaminated soil improvement preparation method of modified mineral composition, comprise the following steps：By attapulgite, vermiculite, sepiolite, zeolite, diatomite difference coarse crushing and roller screen, five kinds of little particle mineral under sieving are uniformly mixed, obtain mixed mineral, spray water to mixed mineral, is then squeezed into shaped minerals composition；The shaped minerals composition is stacked, is dried naturally；Input rotary kiln is roasted, the mineral after being roasted；Mineral after the roasting and flyash, quick lime are compounded, are mixed, obtain mixture；The mixture is milled, to obtain the final product.On the one hand modifying agent composition provided by the invention is acted on by the absorption to heavy metal, precipitation etc., change the existence of heavy metal in the soil, reduce the biological effectiveness and migration of heavy metal；On the other hand, by improving soil texture, the water-retaining property and gas permeability of soil is improved, may advantageously facilitate plant growth. |
