| 摘 要： | 采用室内吸附试验方法,研究了蜂窝煤渣、砂壤土、粉煤灰和山里兰石4种填料对磷素等温吸附特性的影响。结果表明,用Langmuir方程能很好地描述上述4种填料对磷的等温吸附容量,其磷素最大吸附量依次为518.1、4347.8、2777.8和1694.9mg/kg,以蜂窝煤渣的磷吸附量最大、吸附能力最强。4种填料不同用量对磷的最大去除率影响顺序为蜂窝煤渣、粉煤灰、砂壤土、山里兰石,以蜂窝煤渣的去除率为最大,这表明蜂窝煤渣具有较强的去磷能力,是一种较好的磷吸附填充材料。

| Abstract: | The isothermal adsorption characteristics of phosphate by four substrates (honeycomb cinder,sandy loam,fly ash and Shanli-Lanshi) were studied in laboratory.The results indicated that P isothermal adsorption of the four materials mentioned above could well be simulated by the Langmuir equation.The maximum P adsorption capacities of the four substrates were 518.1,4347.8,2777.8 and 1694.9mg/kg,respectively,and the P adsorption capacity and adsorption intensity of honeycomb cinder was the best in the four subs... |
