PURPOSE:To prevent the development of rancidity and propagation of bacteria by providing a device for supplying ozone or active oxygen into a water storage space. CONSTITUTION:A circulating circuit 5 for discharging the water in a water storage space 1 and introducing the water into the space 1 and a pump 6 for circulating waste water to the passage 5 are provided to a trap main body 2. The waste water discharged from a waste water outlet 8 furnished at the bottom of the main body 2 is supplied to an ejector 9 through the pump 6. An ozone-contg. gas is sucked into the ejector 9 from a connected ozonizer 10 by the ejector action when the waste water passes, and ozone is supplied to the waste water. The waste water in the space 1 is sterilized in this way.
