摘　　要：采用二次正交组合实验设计研究了三聚氰胺反应媒循环法由湿法磷酸生产纯净磷酸二氢钾新工艺中三聚氰胺与湿法磷酸浓度、搅拌速度、反应温度、反应时间、三聚氰胺用量诸因素的一次、二次及交互作用对磷收率、硫和氟净化率的影响。找出了相应的数学模型,为复杂反应体系提供了定量描述,根据其数学模型求得磷收率、硫和氟净化率最佳的处理条件。The reaction condition in the process of pure phosphate with modium-melamine recycling method from wet process phosphoric acid have been studied and reported. The effect of different parameters on the recovery efficiency of P, desul-furation and defluoration have been discussed. Mathematical models have been presented. The optimum condition has been gained.
