Description

Technical Field

[0001] The utility model relates to the technical field of asphalt sewage treatment, in particular to a residual oil separation device for asphalt sewage treatment. Background Art

[0002] Water pollution is one of the major environmental issues facing my country. With the development of my country's industry, the discharge of industrial wastewater is increasing. When industrial wastewater that does not meet discharge standards is discharged into water bodies, it pollutes surface water and groundwater. Oily wastewater, which floats on the water surface, and animal and plant fats are rancid, consume dissolved oxygen in the water, and emit unpleasant odors, necessitating wastewater treatment.

[0003] During the asphalt production process, a large amount of oily wastewater is produced. This wastewater not only contains a lot of grease, but also contains a large amount of silt. The mixture of grease, silt and wastewater greatly increases the difficulty of wastewater treatment and is inconvenient for subsequent treatment. The existing separation equipment does not completely separate grease, silt and wastewater, resulting in poor asphalt wastewater separation effect. Therefore, it is necessary to propose an asphalt wastewater treatment residual oil separation device to solve the above problems. Utility Model Content
