The guiding rail is expanded from the bottom side to the side wall of an aerating bath. The gas introducing unit includes a flexible tube(12) and an air diffuser(16). The flexible tube is in connection with the supplying tube(7) of the gas supplying unit in order to receive gas from the gas supplying unit. The flexible tube is bendable to move along the guiding rail. The air diffuser is combined with the air diffuser and introduces gas from the flexible tube to treating liquid in the aerating bath. The drawing unit moves the gas introducing unit along the guiding rail from the treating liquid in the aerating bath.
