Abstract
In order to achieve environmentally friendly treatment of chromium slag,harmless and resourceful treatment experiments were conducted on chromium slag hazardous waste.The experimental results show that under the conditions of 1%activated carbon dosage,2.0 chromium reducing agent dosage,and 10%sodium silicate dosage,harmless treatment of chromium slag hazardous waste can reduce the concentration of hexavalent chromium in chromium slag to below 5 mg/L,meeting the environmental discharge standards.The indicators of iron,aluminum,magnesium,calcium,sulfur,compressive strength,particle size range ratio of 10～50 mm,hexavalent chromium concentration,and total chromium concentration in iron aluminum based composite materials all meet the relevant requirements.关键词
