摘要
Abstract
In this study,the arsenic containing waste salt slag from an arsenic product factory in Yunnan was taken as the research object,and the combined process of roasting and cement solidification was used to treat the arsenic containing waste salt slag.When the roasting temperature was 550℃,the roasting time was2 hours,and the thickness of the material layer was40 mm,the volatilization rate of organic substances was87.6%and the volatilization rate of arsenic was51.4%.When the solidification ratio of the roasted slag was roasted slag∶cement∶polymeric ferric sul-fate∶lime=6∶2∶1∶1,the leaching index of arsenic in the leaching toxicity test of the salt slag solidified body can meet the national requirements of<1.2 mg/L the access of flexible landfills.关键词
