[0051] Specifically, during the sewage treatment process, sewage flows into the main box 1 through the water inlet pipe 11, and continues to flow into the drainage bottom tank 171 after preliminary filtration through the grille 44. The agent is added through the injection pipe 14, and the motor is turned on at the same time. The stirring impeller 131 is used to stir and mix, so as to settle the impurities in the water. With the addition of sewage, the floating plate 35 floats up, and the bottom surface of the floating plate 35 always fits with the upper liquid surface of the sewage. The spring inside the spring telescopic rod 34 is in a stretched state. The floating plate 35 floats up and drives the spring telescopic rod 34 to contract. Then the electric telescopic rod 31 is turned on, and the electric telescopic rod 31 drives the movable block 32 and the horizontal plate A33 to move. Under the limiting effect of 352, the magnetic block B36 below is driven to move accordingly, and the liquid isolation door 39 is contracted inside the contraction groove 354. At this time, the oil absorption felt 353 is used to absorb oil. Then, when the electric telescopic rod 31 is driven to reset, the oil absorption felt 353 is squeezed by the inclined pressure plate 371 to squeeze the absorbed oil. The squeezed oil flows into the liquid storage shell 37 along the oil leakage groove 3712 and the oil pouring chute 3711. In this process, the liquid isolation door 39 slides out to play a blocking effect. Finally, the collected oil is extracted through the connecting hose 375 and the liquid extraction pipe 374. At the same time, under the suction force of the liquid pump, the oil pouring chute 3711 that fits the oil absorption felt 353 can better extract the oil. Repeated movement can achieve oil removal. The effect is that during the movement of the air storage shell 372, the inner guide tube 381 is driven to be compressed inside the outer air pipe 382, ​​and the air inside the outer air pipe 382 enters the air storage shell 372 through the hollow groove 3812 and the one-way pressure valve A3811, and flows out from the short air blowing tube 373, blowing the floating oil attached to the edge of the inner wall of the main box 1, and flows to the middle with the movement of the liquid storage shell 37, and is absorbed by the oil absorption felt 353. The one-way pressure valve provided at the short air blowing tube 373 is used to prevent sewage from entering the interior of the air storage shell 372. In addition, when the movable block 32 moves, the connecting long rod 321 moves accordingly, driving the movable plate 41 and the scraper plate 411 to move and scrape the surface of the grille 44. During cleaning, the telescopic baffle 422 rotates under the action of the connecting rod 421 and the rotating rod, thereby blocking the sewage from flowing to the cleaned surface of the grille 44. When the magnetic strip 43 approaches the magnetic long plate 452, the magnetic long plate 452 is driven to extend from the movable groove 45 and be fixed to the magnetic strip 43 under the action of magnetic attraction, thereby blocking the sewage. At the same time, as the magnetic long plate 452 moves, the laser sensor 48 transmits the signal change to the solenoid valve 46 through the controller, and then the solenoid valve 46 is opened for discharge, and the cleaned impurities are pushed into the waste box 2 for collection through the solenoid valve 46, thereby preventing blocking and finally achieving the purpose of removing surface floating oil in time during the sewage treatment process.
