PROBLEM TO BE SOLVED: To reduce working load necessary for fixing a hollow fiber membrane module to a partition plate in a filtration column. SOLUTION: A projecting part 14 is provided at a cylindrical head part 8 of a hollow fiber membrane module 2. An inserting hole 3 having an inside diameter into which the head part 8 is inserted and the projecting part 14 is not inserted is provided on the partition plate 1. An inserting groove 17 through which the projecting part 14 enters to the mid-way of the inserting hole 3 and a rotating groove 18 where the projecting part 14 entering to the mid-way of the inserting hole 3 is rotated are formed on the circumferential wall of the inserting hole 14. One end of the hollow fiber membrane module 2 is fixed to the partition plate 1 by inserting the head part 8 into the inserting hole 3 while inserting the projecting part 14 into the inserting groove 17 and axially rotating the head part 8 after the projecting part 14 enters up to the rotating groove 18. Then many hollow fiber membrane modules are attached or detached to/from the partition plate without necessitating a C-shaped stop ring or a tool for decreasing the diameter of the ring.
