摘要
本文通过对硫化砷渣稳定化处理研究,采用ENFI-R8和ENFI-Z8稳定剂通过不同添加量的对比考察其对硫化砷的稳定效果,确定了硫化砷渣稳定化的最佳稳定剂及添加量。结果表明:采用ENFI-R8和ENFI-Z8稳定化药剂对硫化砷渣进行处理,处理效果良好,重金属浓度可达到安全填埋《危险废物填埋污染控制标准》(GB18598—2019)中的处置标准。在反应时间为4 h、养护时间为24 h的条件下,硫化砷渣处理采用的稳定剂优选ENFI-Z8稳定剂,稳定剂添加量为40wt.%。
In this paper,through the study on the stabilization treatment of arsenic sulfide slag,ENFI-R8 and ENFI-Z8 stabilizing agents were used to investigate the stabilization effect of arsenic sulfide slag through the comparison of different addition amounts,and the best stabilizer and addition amount for the stabilization of arsenic sulfide slag were determined.The results show that:the treatment effect of arsenic sulfide slag with ENFI-R8 and ENFI-Z8 stabilizing agents is good,and the concentration of heavy metals can meet the disposal standard of Standard for pollution control on the security landfill site for hazardous wastes(GB18598—2019).Under the conditions of reaction time of 4 h and curing time of 24 h,ENFI-Z8 stabilizing agent is the best for arsenic sulfide slag treatment,and the amount of stabilizer is 40wt.%.
