【摘要】 本文通过对工业磷酸一铵废渣的预处理的研究,得出水洗废渣在酸液中的溶解性。工业级磷酸一铵废渣经过水洗、抽滤、烘干、研磨等工序得到水洗滤渣。将水洗滤渣在不同温度、不同浓度的磷酸、硫酸进行溶解实验,用定量滤纸过滤溶液测出滤渣量,初步得出水洗滤渣的溶解性。更多还原

【Abstract】 through pretreatment of industrial ammonium phosphate waste residue, the solubility of industrial ammonium phosphate waste residue in acid solution was obtained. After washing, filtering, drying and grinding of industrial grade ammonium phosphate waste residue, water washing filter slag was obtained. The dissolution experiments of phosphoric acid and sulfuric acid with different concentrations were carried out. The solution was filtered by quantitative filter paper and the amount of filter slag was measured. The solubility of washing filter slag was preliminarily obtained.更多还原
