Electrolytic manganese residue curing/stabilizing treatment method

The invention discloses an electrolytic manganese residue curing/stabilizing treatment method. The method comprises the following steps: (1) adding electrolytic manganese residue into a mixer to mix, and adding water to the manganese residue; (2) adding alkaline medicament in the mixing process for several times, adding sodium hexametaphosphate after adding the alkaline medicament for the first time; (3) placing the mixed electrolytic manganese residue into a rotary releaser to perform ammonia gas continuous treatment, and unloading to obtain cured/stabilized electrolytic manganese residue. On the premise of guaranteeing the curing/stabilizing effect of the manganese residue, the solid waste pH requirement after treatment is satisfied by adding the alkaline medicament for several times, the lime additive amount is obviously reduced, and the manganese curing/stabilizing treatment cost is reduced.
