| description | The invention relates to the technical field of soil remediation, in particular to a preparation method and application of a soil remediation material prepared from coal-based solid waste, the material is mainly prepared from slag, coal gangue, fly ash, sludge, crop straw, a water-retaining agent, a stabilizer, a biological fermentation strain and the like through the steps of mixing, drying, roasting, mixed fermentation and the like. The biological sludge is carbonized to form a loose and porous material, the moisture content of the soil is effectively maintained while the air permeability of the soil is improved, carbon elements can be continuously released to the soil through the plant absorption effect, and heavy metal ions in the sludge can be converted into metal oxides which are difficult to dissolve in water through high-temperature carbonization. Organic matters and inorganic matters are reasonably proportioned, so that the content of the organic matters is increased, the physical and chemical proper |
