铬渣处理处置规范
Application Summary AI generated
This standard specifies the technical requirements for the detoxification treatment, safe disposal, and environmental monitoring of chromite processing residue (chromium slag). It is applied in the metallurgical and chemical industries, specifically at facilities producing sodium dichromate or other chromium compounds, to ensure that the toxic hexavalent chromium in the slag is reduced to trivalent chromium or immobilized before landfill or other disposal methods. The standard is used by environmental regulators and waste treatment operators to control pollution from historical and ongoing chromium salt production sites.
