[0029] The specific implementation method is as follows: when the present invention is used, the oily sewage is injected into the sewage storage tank 1 from the sewage injection pipe 6, and then the device is started, the intelligent control module 31 controls the reciprocating servo motor 25 to rotate, and the reciprocating servo motor 25 rotates through the rotating shaft 24 to drive the oil-absorbing felt 27 on the multiple rotating rods 26 to rotate, and the oil-absorbing felt 27 rotates downward to contact the oily sewage, and then absorbs the oil in the sewage, and then the intelligent control module 31 controls the reciprocating servo motor 25 to reverse 270 degrees, so that the oil-absorbing felt 27 is pressed into The oil absorbed by the oil absorbing felt 27 will be squeezed out in the strip oil squeezing port 22. Then, the intelligent control module 31 controls the reciprocating servo motor 25 to reverse 270 degrees again, and continue to go to the sewage storage tank 1 to contact the sewage and absorb the oil. After the oil in the oil absorbing felt 27 is squeezed out, the baffle 21 can prevent the oil from flowing out. Then, through the strip oil squeezing port 22, the oil can be collected in the oil storage tank 18. By providing the oil leakage groove 23, the oil can be prevented from flowing down along the top of the oil storage tank 18. The oil flows downward from the top of the oil tank 18 and leaks out, and is eventually collected through the strip oil squeeze port 22. During the process of oil removal controlled by the intelligent control module 31, the intelligent control module 31 controls the oil measuring wide-angle lighting lamp 30 to turn on, and at the same time, the optical oil water quality sensor 28 starts to detect the oil content in the sewage. When the oil content is lower than a predetermined value, the intelligent control module 31 controls the filtration sewage pump 2 and the waterproof motor 15 to turn on, and the filtration sewage pump 2 pumps water into the outlet pipe 3 and discharges it through the rotating drain pipe 5. The waterproof motor 15 drives the balance turntable 16 to rotate, and the balance turntable 16 drives the rotating drain pipe 5 to rotate, so that the outlet position can be adjusted, which is convenient for filtering at various positions of the coarse filter 8 and the fine filter 11 to prevent blockage. This enables the present invention to deoil the oil-containing sewage and perform double filtration on the oil-containing sewage, so that one device of the present invention can perform multiple treatments on the oil-containing sewage, reducing the sewage treatment steps, thereby improving the sewage treatment efficiency, and making the actual use effect of the present invention better.
