    摘要: A porous membrane for water treatment of the present invention is made of a resin composition containing 100 parts by weight of a polyvinylidene fluoride based resin, and 5 to 13 parts by weight of a polyvinyl alcohol based polymer having a degree of saponification of 10 to 80 mol %. The porous membrane has a permeation wetting tension of 38 to 72 mN/m, and a tensile strength of 7 to 20 MPa, and thus is characterized by having the excellent mechanical strength and wettability. This is a porous membrane for water treatment essentially containing the polyvinylidene fluoride based resin, which allows water treatment to be highly efficiently performed on raw water (river water, industrial waste water, and the like), in particular. The porous membrane is manufactured, firstly, by melt-extruding a mixture composition containing a polyvinylidene fluoride based resin, a polyvinyl alcohol based polymer, a plasticizer, and a solvent, and then by extracting the plasticizer and the solvent from the substance thus extruded.
