  • 摘要: 针对富含磷水体，以负载Fe合物给水污泥（water supply sludge loaded iron compounds，WSSLICS）为吸附剂，通过SEM、EDS表征、因素影响实验、动力学实验、等温吸附实验进行Wsslics形态特征、除磷效果及机理研究。结果表明，WSSLICS粉末表面疏松微孔，表面物相以Ca6Fe2（SO4）3（OH）12、Zn4Si2O7（OH）2、Ca（B（OH）4）2及NH4Fe（SO4）2为主，反应前后基质表面磷元素含量有明显差异。在单因素研究条件下，当磷溶液浓度为10 mg·L-1，投加量2.0 g·L-1时去除效果明显，且在酸性条件下更有利于磷的吸附去除。动力学实验过程中，磷吸附前2个过程中，固液界面扩散过程起主导作用；第3个反应过程为化学吸附。在WSSLICS除磷等温吸附实验中温度不是决定性因素；低温时实验过程化学吸附起主导作用；Wsslics粉末比较均匀，不需考虑吸附磷过程中的均质与异质作用；WSSLICS对磷的最大平衡吸附量为24.69 mg·g-1。
    Abstract: As absorbents for phosphorus,the morphological characteristics of WSSLICS (water supply sludge loaded iron compounds) were analyzed using SEM,XRD,and EDS.Additionally,the effects and functional mechanism of phosphorus removal were studied via factors,kinetic,and adsorption-isotherm experiments on water samples with a high concentration of phosphorus.The experimental results showed that the surfaces of the Wsslics was loose and porous,and most surfaces were surrounded by Ca6Fe2(SO4)3(OH)12,Zn4Si2O7(OH)2,Ca(B(OH)4)2,and NH4Fe(SO4)2.The elemental compositions of the surfaces of the WSSLICS before and after adsorption with phosphate were significantly different.Under the conditions of a single factor study,the removal of phosphorus was optimized at a phosphorus concentration of 10 mg·L-1,absorbent dosage of 2.0 g·L-1,and under acidic conditions.The dynamic experiment showed that the diffusion process at the solid-liquid interface played a significant role in the first and second steps of phosphorus adsorption;the third reaction process was chemical adsorption.The adsorption-isotherm experiment showed that the temperature did not significantly affect phosphorus removal and chemical adsorption played a leading role at low temperatures.During the experimental process,it was unnecessary to consider the homogeneous and heterogeneous effect on phosphorus adsorption because the powder was uniform.The maximum adsorption capacity of WSSLICS for phosphorus was 24.69 mg·g-1.
