  • 摘要: 以新型赤泥基多孔陶瓷滤球（porous ceramic filter material，PCFM）颗粒为吸附剂，采用动态和静态吸附实验相结合的实验方法研究了PCFM颗粒对沉积物磷的吸附性能。动态吸附实验结果表明，影响PCFM颗粒除磷效果的主要因素有投加量、反应时间、上覆水体pH值和环境温度，最佳吸附反应条件为PCFM投加量8 g，反应时间12 h，上覆水体pH=12，环境温度为50℃。静态吸附实验结果表明，随着反应时间的延长，PCFM对沉积物五种形态磷吸附在12 d左右接近或达到了吸附平衡，此时TP、OP、IP、Fe/Al-P和Ca-P的去除量分别为245.89、69.86、155.25、195.22和-49.01 mg·kg-1。可见PCFM对沉积物磷的吸附性能较好，可进一步应用于富营养化湖泊沉积物磷控制。
    Abstract: The performance of red mud-based porous ceramic filter material (PCFM) particles on the adsorption of sediment phosphorus (P) was studied using dynamic adsorption tests and static adsorption tests. The results of the dynamic adsorption tests illustrated that the main effects on sediment P adsorption were from the dosage of the PCFM particles, reaction time, overlying water pH, and environmental temperature, with optimal conditions of 8 g, 8 h, 12, and 50℃, respectively. The results of the static adsorption tests showed that the best absorption capacity reached equilibrium after 12 d. The adsorption quantities of total P (TP); organic P (OP); inorganic P (IP); P bound to Al, Fe, and Mn oxides and oxyhydroxides (Fe/Al-P); and calcium-bound P (Ca-P) were 245.89, 69.86, 155.25, 195.22, and -49.01 mg·kg-1, respectively. The results of this study showed the strong adsorption capacity of PCFM particles for P and that PCFM can be applied further to control sediment P in eutrophic lakes.
