PURPOSE: A multi-stacked multiple packing tower is provided to wholly contain acid and alkali aqueous solutions and to successively eliminate bad odor components from the aqueous solutions based on one packing tower. CONSTITUTION: A multi-stacked multiple packing tower includes a first storing bath(60) and a second storing bath(70). The first storing bath and the second storing bath are separated by a partition(65). A first packing material(40), a lower spraying nozzle part(30), a second packing material(50), and an upper spraying nozzle part(20) are separately arranged on the storing baths. An aqueous solution from the lower spraying nozzle is collected in the first storing bath. An aqueous solution from the upper spraying nozzle is collected in the second storing bath. The aqueous solutions are repeatedly circulated by separate transferring pumps(5, 6). An upper collecting frame(80) and a lower collecting frame(90) are further formed between the second packing material and the lower spraying nozzle part.
