Arsenic-containing waste slag solidified body and preparation method thereof

The invention relates to an arsenic-containing waste slag solidified body and a preparation method thereof, and belongs to the technical field of environmental protection. The preparation method comprises the following steps of: treating arsenic-containing waste slag, mixing the treated arsenic-containing waste slag and a curing agent prepared from industrial waste slag and a mineral activated material, a modifying agent, aggregates, water and the like, and stirring, forming and curing the mixed materials to obtain the solidified body with high strength and low arsenic leaching rate. Comparedwith the prior art, the solidification process is simple, low in cost, safe and reliable, and solves the problem of arsenic pollution of the arsenic-containing waste slag.
