摘　　要：分析了柱长、浓度、流量和多溶质等因素对分离效果的影响,实验显示不同的溶质具有不同的穿透时间,表明了可以利用活性炭固定床回收表面活性剂。流量越低、活性炭用量越多、表面活性剂浓度越高、多环芳烃浓度越低越有利于表面活性剂的回收和多环芳烃的去除。The activated carbon fixed bed was applied to separate the mixed solution of surface active agent and polycyclic aromatic hydrocarbons (PAHs).The factors that impacted the effects of the test were analyzed covered long column,concentration,flow velocity and solute.The experiment showed that different solutes penetrated in different time,which suggested that the fixed bed could be used to recovery the surface active agent.The lower the flow velocity,the more usage of activated carbon.The higher the surface active agent concentration,the lower the concentration of PAHs would be,which would be useful for the removal of PAHs and the recovery of the surface active agent.
