The present invention provides a combined labyrinthine fluid sterilizing apparatus, comprising a chamber having an inlet and an outlet as well as a blower/fan provided in the chamber. Ultraviolet lamps are mounted in the lumen of the chamber. The lumen of the chamber is divided by a plurality of bafflers having pores. The pores in the adjacent bafflers are arranged to stagger up and down or from side to side. A mesh plate is provided at the pore. The top and bottom plates of the chamber can be flipped open. The baffler is inserted in the slots in the inner side of the front and back plates. The top and bottom plates have the pore and a cover plate which are both covered by a shield. At least one of the bafflers has a pore, and is provided with a one-way openable valve. The blower is mounted at the pore of the baffler. The chamber and the bafflers are coated with a layer of titanium dioxide. According to the present invention, it is possible to add, remove, or replace the baffler, the filter mesh, the blower or the purifying accessories and the like. The one-way openable valve can prevent the polluted water or air from flowing backwards. Further the to and fro winding disinfecting and sterilizing path prolongs the disinfecting and sterilizing process and increases the duration. With the photocatalytic effect of titanium dioxide, the organic substances are effectively decomposed, the dirt is eliminated, and deodorization and sterilization achieved. As a result, an ideal effect of disinfection and sterilization is achieved.
