The invention provides an arsenic sulfide residue transformation and microcapsule curing stabilization method. The arsenic sulfide residue transformation and microcapsule curing stabilization method comprises the following steps that (1) arsenic sulfide residues are used as raw materials to prepare arsenic trioxide; (2) the arsenic trioxide is used as the raw material to prepare 4-hydroxy-3-nitrophenylarsonic acid; (3) an iron-manganese binuclear clustered metal arsonate compound of a porous structure is prepared; (4) silicon coating is conducted on the surface of the iron-manganese binuclearclustered metal arsonate compound of the porous structure; (5) Fe(0)/Al-SBA-15 mesoporous compound stabilizing agent is compounded by means of a hydrothermal reaction; (6) microcapsule curing stabilization treatment is conducted on the iron-manganese binuclear clustered metal arsonate compound with the surface coated with silicon. According to the arsenic sulfide residue transformation and microcapsule curing stabilization method, the 4-hydroxy-3-nitrophenylarsonic acid is prepared through transformation, the metal arsonate compound of the porous structure is prepared finally, compared with atraditional arsenic compound, the prepared metal arsonate compound has the features of being good in stability and low in toxicity, and the toxicity of the arsenic compound is greatly lowered.
