摘　　要：动态吸附方式贴合实际应用,但不同材料的吸附能力差异导致其固定床参数不同。本研究以烟秆生物炭基Mg/Ca复合材料为研究对象,探究不同固定床参数下吸附剂的动态吸附性能。结果表明穿透时间、饱和时间以及吸附容量随填料高度同步变化;流速和初始磷酸盐浓度对穿透曲线影响复杂;溶液pH对动态吸附影响不显著。本研究为吸附剂的固定床使用方法具有实际指导意义。The dynamic adsorption method is suitable for practical application,but the different adsorption capacity of different materials leads to different fixed bed parameters.In this study,tobacco stalk biochar based Mg/Ca composite material was used as the research object to explore the dynamic adsorption properties of adsorbents under different fixed bed parameters.The results showk that the penetration time,saturation time and adsorption capacity change synchronously with the packing height.The influence of flow rate and initial phosphate concentration on the penetration curve is complex.The effect of solution pH on dynamic adsorption was not significant.This study is of practical significance for the application of adsorbent in fixed bed.
