- 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).
