摘　　要：研究了高效除磷材料(Efficient Phosphorus Removal Composite,EPRC)的除磷特性,以及以此材料为填料的吸附柱对模拟含磷废水的除磷效果。试验结果表明:EPRC颗粒在15℃、25℃、35℃时的最大饱和吸附量分别达到1.9535 mg/g、2.281 mg/g、3.6724 mg/g。以EPRC颗粒填充吸附柱处理模拟含磷废水时,停留时间8 h、连续进水、运行8 d,磷的平均去除率为93%,废水pH值略有升高。The characteristics of phosphorus removal by Efficient Phosphorus Removal Composite （EPRC） were developed and the phosphorus adsorption ability of the EPRC material in the filter for synthetic water treatment were investigated. The experiment results suggested that the maximum adsorption capacity of EPRC at 15 ℃, 25 ℃ ,35 ℃ were 1. 9535 mg/g,2. 281 mg/g and 3. 6724 mg/g respectively. In the filter,at HRT of 8 hours,the removal rate could reach to average 93 percent, but the pH raised.
