NOVELTY - The device has an oil-water separating cavity (4) that is provided with a cloth water pipe (3) which is uniformly distributed with several spray pipes. An end portion of a graphite alkenyl net film is provided with a groove (8). The groove is arranged at a bottom of an oil collecting pipe. The oil collecting pipe is connected with an oil collecting cavity. The oil collecting cavity is provided with a sump oil outlet. A bottom of a water cavity (7,10,11) is provided with the cloth water pipe, and connected with a washing water recycling outlet. USE - Forced overflow type graphene oily sewage treatment device. ADVANTAGE - The graphene oily sewage treatment device which ensures high oil removal efficiency, small footprint, pollution resistant ability, water quality requirements for broad, oilfield sewage process conditions and simple matching is obtained effectively. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the forced overflow type graphene oily sewage treatment device.
