Abstract:
The present invention discloses a treatment method for resource recycling of hexavalent chromium-containing residues, belonging to a field of a clean treatment and resource recycling of chromium-containing residues. This method comprises steps as follows: 1) adding water to the hexavalent chromium-containing residues and mixing uniformly; 2) adding mineralizers to a solution obtained in step 1) and stirring sufficiently to obtain a mixed liquid; and the mineralizers are sodium chlorate, sodium perchlorate and hydrochloric acid; 3) treating the mixed liquid by a hydrothermal method or direct heating; 4) after the heating treatment, naturally cooling a solid-liquid mixture to room temperature for holding; 5) separating solid residues and a chromium-containing supernatant, and washing filtered residues with water and then drying; and 6) recycling a chromium-containing solution for returning to a work section, or for a treatment of recycling chromium. This method may achieve full-residue utilization with simple process, low cost, quick effect, large treating capacity and complete detoxification, and has relatively high social benefit and economic benefit.

Claim (Index 7):
The treatment method for resource recycling of hexavalent chromium-containing residues according to  claim 1 , wherein a time for heat preservation in step 3) is 2 to 12 hours.
