中文摘要：
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。
英文摘要：
The aerated filter with porous iron-rich media has a good phosphorus removal performance.Mechanism of phosphorus removal with porous iron-rich 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 iron-rich 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.
