EFFICIENT MANGANESE REMOVAL METHOD

The present disclosure discloses an efficient manganese removal method, wherein a steel slag and polyacrylamide are combined to use and a high-gradient magnetic separator is adopted to perform flocculation and over-magnetic treatment on a water sample, comprising the steps of: adding the steel slag into the water sample to perform adsorption precipitation treatment on the water sample; adding polyacrylamide for flocculation treatment, and enabling the reaction effluent to directly pass through a high- gradient magnetic separator; and performing measurement and analysis on the final effluent water sample. In the present disclosure, a steel slag is used as a water treatment material, so that the problem of environmental pollution caused by massive accumulation of the steel slag is effectively solved, waste can be treated by waste, and good economic, social and environmental benefits can be achieved.
