| titleOfInvention | Preparation method of iron-based arsenic passivation material, iron-based arsenic passivation material prepared by method and application of iron-based arsenic passivation material |
| abstract | The invention relates to a preparation method of an iron-based arsenic passivation material, the iron-based arsenic passivation material prepared by the method and a method for treating arsenic pollution in soil, wastewater and waste residues by using the iron-based arsenic passivation material. The preparation method comprises the following steps: mixing aluminosilicate minerals and composite salts and then roasting; crushing roasting slag obtained after roasting, washing and leaching, and performing solid-liquid separation to obtain solid and liquid; mixing the solid with an iron-based material and water, and performing hydrothermal activation treatment at the temperature of 100-400 ℃; and drying the solid after the hydrothermal activation treatment to obtain the iron-based arsenic passivation material. The iron-based arsenic passivation material is low in cost, but can effectively reduce the arsenic content in wastewater, solidify the form of arsenic in soil and waste residue and reduce the dissolution rate of arsenic. In addition, a preparation process and a technical path of the repair product, which have good effects in wastewater, soil and waste residues, low treatment cost, simple process and environmental protection, are developed by optimizing treatment technical parameters. |
