In the present invention, the waste water to be purified has a BET specific surface area of 25 to 200 m 2 / g, a pore volume of 0.10 to 1.00 mL / g, and an average pore diameter of 0.005 to 0.050 μm. A method for purifying wastewater by contacting with a strand-like TiO 2 photocatalyst while irradiating light, and a BET specific surface area of 25 to 200 m 2 / g and a pore volume of 0.10 to 1 while irradiating light. The present invention relates to the use of a strand-like TiO 2 photocatalyst having a 0.000 mL / g and an average pore diameter of 0.005 to 0.050 μm for wastewater purification. |
