[0002] As we all know, the cleaning wastewater from tanker tank washing is oily wastewater mixed with oil substances and sewage. If this kind of sewage is not discharged without treatment, it will affect the marine environment. However, if the oily wastewater is stored together, the volume of ship sewage storage will increase. Therefore, it is necessary to use sewage treatment equipment to conduct preliminary treatment of the oily wastewater to reduce the volume of sewage storage.

[0003] At present, in the related technology, after searching, the utility model with patent publication number CN216946569U discloses a tanker tank washing sewage treatment device, including a sewage tank, a sewage pipe and an addition pipe are opened through the upper end of the sewage tank, a first gear is rotatably connected to the lower end of the sewage tank, a plurality of second gears are rotatably connected to the lower end of the sewage tank, a double-axis motor is installed inside the protection box, one of the output shafts of the double-axis motor is transmission-connected to the first gear, and the other output shaft of the double-axis motor is transmission-connected to a turntable, a first cylinder is fixedly connected to the lower end of the sewage tank, a filter screen is fixedly connected to the lower end of the first cylinder, a scraper abutting the filter screen is fixedly connected to the peripheral side of the turntable, a discharge pipe is penetrated through the central lower end of the filter screen, a second cylinder is fixedly connected to the lower end of the sewage tank, an inclined plate is fixedly connected to the lower end of the second cylinder extending out of the filter screen, and a drain pipe is penetrated through the left end of the inclined plate.
