摘　　要：废水除磷工艺种类繁多,需要我们根据废水情况来制定相应的除磷方法。由于氧化镁烟气脱硫废渣中含有氧化镁、硫酸镁、氢氧化镁,这些化学成分可以在一定条件下释放出大量镁离子,能够与废水中的磷酸根反应生产稳定的沉淀物,所以氧化镁烟气脱硫废渣除磷具有良好的应用效果和应用前景。There are many kinds of dephosphorization processes in wastewater,so we need to formulate corresponding phosphorus removal methods according to the situation of wastewater.Magnesium oxide flue gas desulfurization residue contains magnesium oxide,magnesium sulfate,magnesium hydroxide,these chemical components can release a large number of magnesium ions under certain conditions,and can react with phosphate in wastewater to produce stable sediment.Therefore,magnesium oxide flue gas desulfurization residue has good application effect and application prospect.
