PROBLEM TO BE SOLVED: To provide a vortex flow acceleration photocatalyst liquid treating device in which a photocatalyst area is increased. SOLUTION: A double effect liquid treating device, in which a vortex flow rotated in acceleration is formed in an introduced liquid and ultraviolet ray sterilization and photocatalyst effect are reinforced, is composed by attaching a hollow quartz tube 2 inside a tube body 1 where a photocatalyst is applied to an inner wall, attaching an ultraviolet ray lamp to its inside, providing a liquid entrance tube 11 and a liquid exit tube 12 respectively on the upper end and the lower end of the tube body 1, making the upper end provided with the liquid entrance tube of the tube body separable from the tube body, providing an acceleration structure on a liquid entrance tube exit inside the tube body, providing a plurality of flow guiding passages in the acceleration structure, and providing a multiple photocatalyst reinforcing device parallel between the tube body 1 and the quartz tube 2. By forming the vortex flow of high-speed rotation inside the tube body, a sterilization effect is strengthened and the effect of decomposing organic contaminants is improved. Also, a color comparison chart on which the color of a depth different from an ultraviolet ray intensity indication lamp 4 is printed is added and a user is made to easily understand the intensity of ultraviolet rays.
