Cascade adsorption process stage design method

The invention discloses a series design method of a cascade adsorption process, which enables series design of the cascade adsorption process to have perspectiveness and can avoid waste of equipment and adsorbent dosage cost caused by excessive series. The final-stage discharged liquid stably meets the concentration requirement of a target object, and a concentration feedback system does not need to be added; the minimum required series can be designed through small tests and calculation, and convenience and rapidness are achieved. 本发明公开了一种串级吸附工艺级数设计方法，本发明使串级吸附工艺级数设计具有前瞻性，可避免级数过多造成的设备和吸附剂用量成本浪费；末级出液稳定达到目标物浓度要求，无需添加浓度反馈系统；设计最少所需级数可通过小试和计算得到，方便快捷。
