Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1-6, a petrochemical sewage treatment device comprises an air flotation tank main body 1, an aeration area 2 is arranged on the right side of the air flotation tank main body 1, a water inlet 8 fixedly connected with the air flotation tank main body 1 is arranged on the right side of the aeration area 2, a partition plate 3 fixedly connected with the air flotation tank main body 1 is arranged on the left side of the aeration area 2, a conveying pipeline 4 is fixedly connected to the bottom end of the aeration area 2, the other side of the conveying pipeline 4 penetrates through the air flotation tank main body 1 to be communicated with an external dissolved air tank, a rotating shaft 5 is rotatably connected to the top of the conveying pipeline 4, four air outlet pipelines 6 are fixedly connected to the top of the rotating shaft 5 and are distributed at equal intervals, a plurality of air outlet holes 601 are formed in the surface of the air outlet pipeline 6, dissolved air water is conveyed outwards through a plurality of air outlet pipelines 6, so that the contact area of the dissolved air water and sewage is increased, the air flotation effect during sewage treatment is improved, and sewage treatment is prevented from being caused by poor air flotation effect and sewage needs to be treated for many times.
As shown in fig. 3 and 4, further, the outlet pipes 6 have the same structure, and the outlet holes 601 are located on the same side of the outlet pipes 6, so that when the gas-dissolved water is output from the outlet pipes 6, the outlet pipes 6 rotate to stir the water body because the outlet holes 601 are located on the same side of the outlet pipes 6, and the air bubbles separated from the gas-dissolved water are fully mixed with the sewage.
As shown in fig. 2 and fig. 3, further, a filter screen 7 matched with the air outlet pipe 6 is arranged outside the air outlet pipe 6, the filter screen 7 is fixedly connected with the bottom of the aeration area 2, and when gas in dissolved air water is separated out, the gas collides with the filter screen 7, so that the bubbles become smaller, and the air flotation effect is better due to smaller bubbles.
