| titleOfInvention | A kind for the treatment of method for detoxication of the extraction of waste residue containing Cr VI recovery chromium |
| abstract | The invention discloses the treatment method for detoxication that a kind of waste residue containing Cr VI extracts recovery chromium, belong to the cleaning treatment of chromium slag and the cycling and reutilization field of resource.This method concretely comprises the following steps：1）Water is added into chromyl waste residue, is well mixed；2）To step 1）Sodium sulphate, sodium chlorate and sulfuric acid are added in resulting solution, is sufficiently stirred, obtains mixed liquor；3）Using hydro-thermal method or directly heat processing mixed liquor；4）After heating, solidliquid mixture is naturally cooled to room temperature, stand；5）Solid slag is separated with supernatant containing chromium, and residue washing is dried；6）By supernatant and the water CaCl of washing filter residue 2 Settlement treatment is carried out, then centrifuge washing dehydration is carried out to precipitation, is dried；7）Chromium-containing solution is reclaimed and returned in workshop section, or carries out reclaiming chromium processing.This method technique is simple, cost is low, quick, treating capacity is big, removing toxic substances is thorough, it is possible to achieve full slag utilizes, and has higher Social benefit and economic benefit. |
