The invention discloses a coal ash acid soluble slag treating method. The coal ash acid soluble slag treating method includes the following steps that pulping is carried out, wherein coal ash acid soluble slag and water are evenly mixed; modification is carried out, wherein slurry obtained in the step a and fatty acid are evenly mixed and react; and separation is carried out, wherein a modified product obtained in the step b is subject to solid-liquid separation, and a solid phase product and a liquid phase product are obtained. By means of the method, the content of chlorine ions in the coal ash acid soluble slag can be efficiently reduced, and the environment is protected. 本发明公开了种粉煤灰酸溶渣的处理方法，包括以下步骤：制浆：将粉煤灰酸溶渣与水均匀混合；改性：将步骤a所得浆料与脂肪酸均匀混合、反应；分离：将步骤b所得改性产物进行固液分离，得到固相产物和液相产物；通过本发明的方法可以高效降低粉煤灰酸溶渣中氯离子含量，保护环境。
