摘要: 采用多孔富铁填料的曝气过滤装置具有优良的除磷性能,理论分析研究了多孔富铁填料的除磷机理,通过铁细菌测定、电镜扫描、红外光谱分析等实验对其除磷机理进行了验证。结果表明,多孔富铁填料除磷为化学除磷过程,铁的形态转化中存在铁细菌的氧化作用,沉淀物以碱式磷酸铁为主。Abstract: The aerated filter with porous ironrich media has a good phosphorus removal performance. Mechanism of phosphorus removal with porous ironrich media was discussed on theoretical analysis and verified with experiments on iron bacteria determination,scanning electron microscopy and infrared spectrum analysis. The results showed that phosphorus removal with porous ironrich was a chemical precipitation. There was biological oxidation of iron bacteria in the valent state transformation of iron. Basic iron phosphate was the primary constituent of precipitate.
