摘要:采用等温吸附、吸附动力学实验研究泥灰页岩、黑色页岩、蜂窝煤渣和河砂的吸附特征。结果表明: 4 种
不同填料对磷的吸附量均随着起始浓度的增大而增大,蜂窝煤渣和泥灰页岩对磷的吸附量明显大于河砂和黑
色页岩。在吸附动力实验中,分析吸附动力学曲线表明: 填料对磷素的吸附动力学具有相似的特征,即经过快、
中、慢的反应阶段并最终达到平衡。4 种填料对于磷素的吸附量由大到小依次为蜂窝煤渣、泥灰页岩、河砂、黑
色页岩。比较实验结果,蜂窝煤渣和泥灰页岩比较适合作为除磷的人工湿地填料。

Abstract: In this study,the phosphorus adsorption characteristics of four fillings included slimy shale,
black shale,b cinder and river sand which were used in the constructed wetland were studied by iso-
thermal adsorption experiment and adsorption ics experiment. The results of the isothermal adsorption ex-
periment showed that the phosphorus adsorption capacity of the four fillings i
