摘要：【中文】本发明涉及一种粉煤灰协同稳定化药剂靶向固砷的方法，属于重金属污染治理技术领域。本发明将硅酸盐水泥、粉煤灰加入到含砷污泥中混合均匀得到混合物A；在混合物A加入稳定化药剂并混合均匀得到混合物B；搅拌条件下，将混合物B加入到水中混合均匀得到水泥浆，将水泥浆进行老化处理40~60min；将老化处理的水泥浆倒入模具中成型，成型块脱模后自然养护7~28d即得无害化固化块。本发明中的粉煤灰作为砷固化过程中的促进剂可增强固化块的抗压强度；稳定化药剂可针对性固砷，提高含砷污泥的稳定性。 【EN】The invention relates to a method for targeting arsenic fixation by a synergistic stabilization medicament of fly ash, belonging to the technical field of heavy metal pollution treatment. According to the invention, Portland cement and fly ash are added into arsenic-containing sludge and uniformly mixed to obtain a mixture A; adding a stabilizing agent into the mixture A and uniformly mixing to obtain a mixture B; under the stirring condition, adding the mixture B into water, uniformly mixing to obtain cement paste, and aging the cement paste for 40-60 min; and pouring the aged cement paste into a mold for molding, demolding the molded block, and naturally curing for 7-28 days to obtain the harmless cured block. The fly ash in the invention can be used as an accelerant in the arsenic curing process to enhance the compressive strength of the cured block; the stabilizing agent can be used for pertinently fixing arsenic and improving the stability of the arsenic-containing sludge.
