Method for producing special-purpose modified mineral materials for black-odor rivers

The invention relates to a method for producing special-purpose modified mineral materials for black-odor rivers, which comprises the following steps: step 1, attapulgite, zeolite and bentonite ores are dried, mixed and coarsely crushed; step 2, calcium nitrate and lanthanum chloride are added to mix and obtain hybrid particles; step 3, water is sprayed to extrude the hybrid particles to be flake clay mixture; step 4, the flake clay mixture is uniformly mixed with polyferric chloride and poly aluminum chloride; and step 5, the special-purpose modified mineral materials for the black-odor rivers are obtained by drying and grinding. The method for producing special-purpose modified mineral materials for black-odor rivers are easy to obtain raw mineral materials, is low in cost, obtains the special-purpose modified mineral materials for the black-odor rivers by optimizing a series of steps such as mixing, crushing, squeezing, drying and grinding and the like particularly by adding the calcium nitrate and the lanthanum chloride during the production process, achieves low cost purification treatment of the black-odor rivers, is simple in operation step and easy to control, and is suitable for large-scale applications in industry.
