The present invention provides an oil-water separating device and a floating oil collecting system. The device comprises an oil gathering chamber (2) enclosed by a wall (1). At least a part of the surface of the wall (1) is covered with a porous, oleophilic and hydrophobic layer (3), which allows penetration of water and oil. The device further comprises a fixed layer (4) covering on the surface of the porous, oleophilic and hydrophobic layer (3) for limiting the flowing of the porous, oleophilic and hydrophobic layer (3), which allows the penetration of water and oil. The pore diameter of said porous, oleophilic and hydrophobic layer (3) is 300-850µm, and the porosity is 10-40%.
