[Prior Art] • It is expected that the photocatalyst has the functions of sterilization, antifouling, air purification, deodorization, etc., making it a hot product in the industry, and the various effects produced are collectively referred to as “photocatalytic effects”. "Photocatalytic reaction" is the irradiation of ultraviolet light or sunlight, so that the electrons on the surface of the photocatalyst absorb enough energy to jump to the high-energy orbit, and form a positively charged hole at the position where the electrons are separated (h〇 Les), the hole will oxidize the hydroxyl radicals liberated by nearby water molecules (that is, to capture its electrons to make it an extremely active OH radical; and the hydroxyl radicals - have encountered organic Substance will recapture the electrons, causing the organic matter to decompose due to the destruction of the bond to achieve the goal of decontamination and sterilization. Photocatalysts are now widely used in the surrounding environment, especially for purifying the air. And a fluid device such as water. In most commercially available fluid purification devices, the photocatalyst is generally applied to the inner wall or filter of a commercially available fluid purification device in the form of a film, for example, US Patent No. 5'790'934 and 6'063'343 discloses a reactor comprising a plurality of fans coated with a photocatalyst, and the external light/titanium dioxide photooxidation device of the invention is also disclosed in the Republic of China Patent Publication No. 4,222,162. ph〇t〇_〇xidati〇n, 51287054

'This fall-off phenomenon is more serious in water purification devices because the current Unable to stabilize and how to effectively use the photocatalytic reaction efficiency is extremely difficult to find a solution. In addition, in order to effectively utilize the photocatalytic reaction efficiency, in the water purification skirt, some people have tried to directly add the photocatalyst into the sewage to form a liquid condensate and then irradiate with ultraviolet light to decompose the organic matter in the water, for example. A soiled decontamination apparatus is disclosed in U.S. Patent No. 5,294,315, the entire disclosure of which is incorporated herein by reference. However, after the completion of the water purification treatment, since the particle size of the commercially available photocatalyst is generally between tens of nanometers and hundreds of nanometers, the photocatalyst must be separated from the water by the filter film, but it is used for a long time. After that, the pores of the film will be filled by the photocatalyst and easily become blocked. In this case, the water should be shut down and then replaced (4). The cost of the whole purification process is increased, and the purification efficiency is greatly reduced. Although the industry has applied photocatalyst to non-rigid carriers such as fiber or fabric, the use of such products is mostly & improving the product's own sterilization and self-cleaning (seif-c eaning) ability, no one has ever It is used in any purification method or device. It can be seen from the above that how to avoid the clogging of the filter film of the purification device, and the photocatalyst can be stably fixed, and the reaction efficiency of the photocatalyst is effectively exerted. 1287054 There is still a demand for the industry. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a photocatalyst-containing composite fiber which can stably fix a photocatalyst, can effectively increase the photocatalytic reaction efficiency, and has a long service life and can be repeatedly used. Another object of the present invention is to provide a method for producing the above photocatalyst-containing composite fiber by a composite spinning method. It is still another object of the present invention to provide a method for purifying a contaminated fluid using the above photocatalyst-containing composite fiber.

The method for purifying the contaminated fluid using the photocatalyst-containing composite fiber of the present invention comprises the steps of: compounding a plurality of photocatalysts The fibers are placed in a contaminated fluid and applied to light of a wavelength in the visible or ultraviolet range to purify the contaminated fluid. The photocatalyst-containing composite fiber of the invention is prepared by a composite spinning method, so that the photocatalyst can be stably fixed on the surface of the fiber, and the photocatalyst is not applied to the inner wall of the device or other carrier, and only the surface can be made. The photocatalyst is fixed by the photocatalyst, and the photocatalyst is added to the fiber during the preparation of the fiber, and the fiber itself has a large surface area, thereby increasing the fixing area of the photocatalyst, so that the photocatalyst can be effectively enhanced by the light irradiation. Reaction efficiency. Further, since the photocatalyst is stably fixed and is not easily peeled off, the photocatalyst-containing composite fiber of the present invention can be reused while prolonging the service life. In the method for purifying the contaminated fluid of the present invention, the photocatalyst-containing composite fiber is directly placed in the contaminated fluid, so that the contaminated fluid can sufficiently adhere to the photocatalyst-containing composite fiber with more photocatalyst on the surface. Contact the light and irradiate it with light of a wavelength in the visible or ultraviolet range to react the organic contaminants in the fluid with the photocatalyst, thereby efficiently purifying the fluid, and the fiber is not large in size.
