Referring to fig. 1-5, the present invention provides a technical solution, an integrated sewage treatment device for oily sewage, comprising an outer tank 1 and a canister 2 disposed in the middle of the inner cavity of the outer tank 1, the top end of the canister 2 is connected with a water inlet pipe 11, a disc housing 3 is fixedly sleeved on the inner cavity of the canister 2 near the top end, through holes are respectively disposed on the top and bottom surfaces of the disc housing 3, a central shaft rod 41 is rotatably sleeved on the upper surface of the disc housing 3 at the middle position, the central shaft rod 41 is uniformly and fixedly connected with a rotating plate 4 on the outer wall of the bottom end of the inner cavity of the disc housing 3, an impeller 5 is rotatably sleeved on the bottom end of the inner cavity of the water inlet pipe 11, the rotating shaft of the impeller 5 is butted with the top end of the central shaft rod 41, two through holes disposed on the side surface of the disc housing 3 are respectively connected with a first connecting pipe 31, the outside of the outer tank body 1 is provided with a spiral conveying part 6 along the vertical direction, the outer end of the first connecting pipe 31 is connected with an output port on the top end of the spiral conveying part 6, the outer end of the second connecting pipe 32 is connected with an input port at the bottom end of the spiral conveying part 6, a cleaning box body 8 for removing a lipophilic sphere surface oil film is arranged at a position, close to the spiral conveying part 6, of the second connecting pipe 32, and a through hole is formed in the bottom end face of the spiral conveying part 6.

In conclusion, sewage enters the filter tank 2 through the water inlet pipe 11 to be filtered; the sewage pushes the impeller 5 to rotate in the flowing process, and the impeller 5 drives the rotating plate 4 to stir the oleophilic sphere in the disc shell 3 through the central shaft lever 41; in the process that sewage flows downwards through the disc shell 3, oil stains are absorbed by the lipophilic sphere, and the oil stains form an oil film on the surface of the sphere; the rotating plate 4 discharges the sphere attached with the oil film into the second connecting pipe 32, the sphere slides into the cleaning box body 8, after the oil film on the surface of the sphere is removed in the cleaning box body 8, the sphere enters the bottom end of the spiral conveying part 6, and then the sphere is upwards conveyed by the spiral conveying part 6 and discharged into the first connecting pipe 31; the ball body slides into the disc housing 3 through the first connection pipe 31, so that the ball body can circularly adsorb and remove the oil stains in the sewage.

The sewage treatment principle is that the sewage is treated by a coalescence method, namely, the sewage is separated by utilizing the difference of the affinity of oil and water relative to a coalescence material, the surface of a spherical material is a lipophilic material, the material has appropriate oleophilic hydrophobicity, and the contact angle between the lipophilic material and the oil is optimally less than 70 degrees.

In this embodiment, the lipophilic spheres filled in the disc housing 3 are one of wax-like spheres, polyolefin-based spheres and polystyrene-based spheres.

In this embodiment, the rear wall of the first connecting pipe 31 is tangent to the rear wall of the inner cavity of the disc housing 3, and the front wall of the second connecting pipe 32 is tangent to the front wall of the inner cavity of the disc housing 3; so that the oleophilic sphere is convenient to discharge into the disc shell 3 and the oleophilic sphere is convenient to discharge from the disc shell 3 when in use.

In this embodiment, the height of the input port of the spiral conveying part 6 is lower than that of the disc housing 3, and the height of the output port of the spiral conveying part 6 is higher than that of the disc housing 3; when in use, the lipophilic sphere is convenient to form a circular motion track.
