Zusammenfassung:	PROBLEM TO BE SOLVED: To combine three columns into single one to dispense with auxiliary facilities, to reduce an installation space and also to lower running cost. SOLUTION: A raw liquid is fed into a distillation column through a feed nozzle 3. The distillation column has a first distillation part equipped with an enriching section formed above the feed nozzle 39 and a stripping section formed below the feed nozzle 39, a second distillation part equipped with a concentration section connected to the upper end of the first distillation part and formed above the upper end thereof and a stripping section formed below the upper end thereof, and a third distillation part equipped with an concentration section connected to the lower end of the first distillation part and formed above the lower end thereof and a stripping section formed below the lower end thereof. The concentration section of the first distillation part and the stripping section of the second distillation part, and the stripping section of the firs distillation part and the concentration section of the third distillation part are made adjacent to each other via dividers 62, 64, respectively.
