摘要： Devices used in an oil-containing wastewater treatment system are simplified by efficiently combining differences in processes used in the system.The oil-containing wastewater treatment system includes a separation tank that separates oil by flotation, the separation tank being arranged in a supply path of raw water which is oil-containing wastewater; a membrane filtration tank that is arranged on the downstream of the separation tank and that includes therein a membrane separation module including a hollow fiber membrane or a flat sheet membrane, and a diffuser for generating air bubbles, the diffuser being disposed below the membrane separation module; a supply pipe that supplies the raw water from the separation tank to the membrane filtration tank through a circulating pump; and a return pipe that returns unfiltered water containing the oil and air bubbles from the membrane filtration tank to the separation tank.
