以含磷废水为研究体系,研究了以氯化镁、碳酸氢铵为复合沉淀剂去除水中磷过程的工艺条件.该工艺过程保留了化学沉淀法操作弹性大、除磷效率高、操作简单的特点,生成的MgNH4PO4*6H2O结晶大,容易过滤.该除磷体系中最佳的工艺条件为:初始液pH值为9.4,沉淀剂加入量[NH4+]/[P]=1,[Mg2+]/[P]=1.3(摩尔比).
- Abstract:
-
Taking phosphorus-containing wastewater as the research system, the process conditions of removing phosphorus from water with magnesium chloride and ammonium bicarbonate as composite precipitants were studied. The process retains the characteristics of high elasticity, high phosphorus removal efficiency and simple operation by chemical precipitation method, and the generated MgNH4PO4*6H2O crystallization is large and easy to filter. The optimal process conditions in this phosphorus removal system are: the pH value of the initial solution is 9.4, the amount of precipitant added is [NH4+]/[P]=1, [Mg2+]/[P]=1.3 (molar ratio).
