A water baffle 7 is fixedly connected to the inner wall of the tank body 1 at a position away from the sewage inlet pipe 5. A plurality of through sludge discharge holes 11 are provided at the bottom of the water baffle 7. The tank body 1 is fixedly connected through the position on one side of the water baffle 7 away from the sewage inlet pipe 5 with a water outlet pipe 6.

[0039] The sewage inlet pipe 5 discharges wastewater to the side of the water baffle 7 on the inner wall of the tank body 1 away from the sewage inlet pipe 5. When passing through the sewage inlet pipe 5, the propeller 16 inside the sewage inlet pipe 5 rotates, so that the water pressure speed is buffered. The wastewater in the tank body 1 shall not exceed the upper edge of the water baffle 7. At this time, the sewage inlet pipe 5 is closed. Chemical drugs are added to the wastewater inside the tank body 1 to precipitate the sludge and float the oil in the wastewater. At this time, the sewage inlet pipe 5 is opened to continue discharging wastewater. When the wastewater reaches the position of the oil outlet 4 at the top of the tank body 1, the oil floating on the water surface is discharged from the oil outlet 4. A plurality of through sludge discharge holes 11 are provided at the bottom of the water baffle 7 inside the tank body 1 to prevent the wastewater on the side of the tank body 1 where the water baffle 7 is away from the sewage inlet pipe 5 from being completely precipitated. However, after re-precipitation, the water outlet pipe 6 can be opened to discharge the water. When there is too much sludge at the bottom of the tank body 1, the sludge discharge baffle 15 can be pushed open through the stepping structure, and the sludge at the bottom inside the tank body 1 is discharged.

[0042] When the utility model is in use, waste water is discharged through the sewage inlet pipe 5 to the side of the water baffle plate 7 on the inner wall of the tank body 1 away from the sewage inlet pipe 5. When passing through the sewage inlet pipe 5, the propeller 16 inside the sewage inlet pipe 5 rotates to buffer the water pressure speed. The waste water discharged from the tank body 1 shall not exceed the upper edge of the water baffle plate 7. At this time, the sewage inlet pipe 5 is closed, and chemicals are added to the waste water inside the tank body 1 to make the sludge in the waste water settle and the oil float. At this time, the sewage inlet pipe 5 is opened to continue to discharge the waste water. When the waste water reaches the position of the oil outlet 4 at the top of the tank body 1, the oil in the waste water inside the tank body 1 is discharged from the oil outlet 4, flows into the oil storage tank 2 through the arc-shaped oil filter hopper 3, and the sewage inlet pipe 5 is closed to make the waste water settle again. The bottom of the water baffle plate 7 in the tank body 1 is provided with a plurality of sludge filters penetrating therethrough. The mud discharge hole 11 prevents the wastewater on the side of the tank body 1 located on the water baffle 7 away from the sewage inlet pipe 5 from not being completely precipitated. However, it is precipitated again and the filtered wastewater can be discharged through the outlet pipe 6. When there is too much sludge at the bottom of the tank body 1, the foot pedal 9 can be stepped on. The foot pedal 9 is rotatably connected to the end of the push rod 13 away from the sewage outlet 19. The push rod 13 is subjected to force on the support frame 14. At this time, the sludge discharge baffle 15 is pushed open by the push rod 13, and the sludge at the bottom of the tank body 1 is discharged. The spring 10 fixedly connected between the bracket 8 and the sludge discharge baffle 15 can make the sludge discharge baffle 15 rebound to its original position.
