摘  要:以磷肥厂含磷废水为原料,改进传统处理工艺,采用新型两段式沉淀法处理工艺得到含磷渣,再添加适量硫酸反应制备过磷酸钙。该工艺流程短、操作简便、磷回收率高,在处理含磷废水的同时,得到过磷酸钙,产品质量符合GB 20413-2006标准要求,经济效益明显,为磷肥企业含磷废水的处理利用提供有效途径。Phosphorus slag was obtained through the new two-stage treatment process with phosphorus wastewater in phosphate fertilizer plant by improving the traditional process. Calcium superphosphate was prepared with phosphorus slag and the appropriate amount of sulfuric acid. The process was characterized by short process flow, simple operation, high P2O5 recovery rate, and obtained Calcium superphosphate by treating phosphorus wastewater. The product quality met the requirement of GB 20413-2006. The process has obvious economic benefits, is an effective approach to the treatment of phosphorus wastewater in phosphate fertilizer plant.
