One end of the second conduit 21 is connected to the circulation pump 20, and the other end is connected to the upper side of the treatment vessel 30, so that the raw liquor flows from the upper side to the lower side of the treatment vessel 30.
The treatment vessel 30 is an aldehyde-removing generator, preferably cylindrical in shape, and is made of a light-transmitting material such as colorless transparent glass. The photochemical catalyst layer 60 is placed inside the processing container 30, the photochemical catalyst layer 60 can be placed freely and can be fixed at the bottom of the processing container 30, a detachable fixing mode is preferably selected, one of the detachable modes is that a circle of annular grooves are formed in the bottom of the processing container 30, the corresponding photochemical catalyst layer 60 is of a hollow annular structure, and the photochemical catalyst layer 60 is inserted into the grooves for fixing.
The photochemical catalyst layer 60 is a hollow cylinder fixed at the middle of the treatment vessel 30, and a screen is formed on the side surface thereof, preferably a screen made of SUS316 material, and the photochemical catalyst is supported on the screen in advance, one of the modes of supporting is a photocuring support.
