Abstract: Provided are a porous outflow pipe and an osmosis module comprising same. A porous outflow pipe for forward osmosis or pressure-retarded osmosis, according to one embodiment of the present invention, comprises: a hollow pipe provided with a plurality of first through-holes and second through-holes in the lengthwise direction through which a fluid flows in and out; a bypass pipe arranged concentrically inside the hollow pipe in the lengthwise direction; and a partitioning plate formed along the circumference of the bypass pipe, for preventing mixing of a fluid introduced through the front end side of the hollow pipe and a fluid introduced through the second through-holes.
