| description | PROBLEM TO BE SOLVED: To provide an apparatus for cleaning water at a low running cost in which the whole photocatalyst is easily irradiated with UV rays, so that cleaning efficiency of dioxins and coplanar PCBs or the like is enhanced, which can be made small in size and which can clean even dense harmful waste water such as scrubber water to the level of the effluent standard or lower. SOLUTION: The apparatus is equipped with a cylinder 20 having light transmitting property and housing a photocatalyst 10 inside, a casing 30 disposed outside of the cylinder 20 and mounting a light source 15 to irradiate the photocatalyst 10 with exiting light, and a conduit 40 having the top end disposed in the cylinder 20 to bubble the waste water passing through the cylinder 20. If necessary, a plurality of holes are formed in a part of the conduit 40 in the cylinder 20, the other end of the conduit 40 is connected to the space 24 between the cylinder 20 and the casing 30, or the apparatus is further equipped with a means to supply an oxidizing agent into the conduit 20.
