Abstract

[Problem] The present invention is to provide a filtration device (1) capable of maintaining a filtration performance at a low cost and also for a long period of time as well as a water treatment method using the filtration device (1). [Solution] A filtration device (1) includes an external tubular portion (2) which encloses a filter material (3), a first filter material fixing portion (41) which fixes an upper end portion and a lower end portion of the filter material (3), a tube internal movable portion (5) which is provided at a position which faces the first filter material fixing portion (41) so as to move along an axial direction inside the external tubular portion (2), a second filter material fixing portion (42) which is provided in the tube internal movable portion (5) and fixes the upper end portion of the filter material (3), and a stopper portion (6) which regulates movement of the tube internal movable portion (5) and regulates the movement of the tube internal movable portion (5) at a position in which the filter material (3) is constant in filling density.
