Treatment method of thallium-containing waste residues

The invention provides a treatment method of thallium-containing waste residues. The treatment method comprises the following steps: S1, providing synthetic sulfur within 10 days from a synthesis date; wherein the synthetic process of the synthetic sulfur comprises the following steps: mixing sulfite and sulfide salt in an acid solution to obtain the synthetic sulfur, s2, the thallium-containing waste residues, the synthetic sulfur and water are subjected to a hydrothermal reaction together, and treatment liquid and solid thallium treatment residues are obtained; wherein the temperature of the hydrothermal reaction is 180 to 240 DEG C. According to the method, stable solidification of thallium can be achieved, and the leaching risk of thallium in the waste residues is reduced. 本发明提供一种含铊废渣的处理方法，包括步骤：S1，提供距离合成日期在10天内的合成硫；其中，所述合成硫的合成过程包括：将亚硫酸盐和硫化盐在酸性溶液中混合，得所述合成硫；S2，将所述含铊废渣、所述合成硫、以及水一同进行水热反应，得处理液和固铊处理渣；其中，所述水热反应的温度为180～240℃。本发明能够实现铊的稳定固化，降低废渣中铊的浸出风险。
