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 4h and curing time of 24h, ENFI-Z8 stabilizing agent is the best for arsenic sulfide slag treatment, and the amount of stabilizer is 40wt.%.
