[0002] Coal chemical wastewater refers to industrial wastewater produced by processes such as coal coking, distillation and gasification. It is generally brown or brown in color. The composition of coal chemical wastewater is complex. The oil entrained in the wastewater is mainly tar, including light oil with a specific gravity of 0.96-0.98 and heavy oil with a specific gravity of 1.02-1.04. The oil residue is mainly tar residue, which is a hazardous waste.

[0003] Patent number: CN215756843U, proposes a coal chemical wastewater precipitation pretreatment device. By energizing the electrode plates, the wastewater can be electrolyzed, thereby generating a large number of bubbles.

[0025] When the pressure pump is started, the oil and impurities floating on the surface of the coal chemical wastewater will be sucked into the interior of the suction shell 17, and then enter the interior of the rotating tube 11 through the sliding tube 16. The oil and impurities entering the rotating tube 11 enter the interior of the collecting box 8 through the connecting tube 9, and then the pressure pump is started to collect the oil and impurities floating on the surface of the coal chemical wastewater, thereby preventing the oil and impurities from entering the subsequent processing procedures. At the same time, it avoids the situation where the oil-absorbing cloth repeatedly uses the absorbed oil when absorbing the floating oil, causing the oil on the oil-absorbing cloth to come into contact with the coal chemical wastewater again.

[0027] When the threaded rod 12 is rotated, the threaded rod 12 moves toward the inside of the processing box 1, so that the threaded rod 12 pushes the rotating plate 13, and the rotating plate 13 drives the connecting rod 14 and the fixed plate 15 to move. The fixed plate 15 drives the sliding tube 16 to slide downward inside the rotating tube 11, and the sliding tube 16 pushes the suction shell 17 downward, thereby adjusting the height of the suction shell 17 and the oil and impurities.
