Technical Field

[0001] The utility model relates to the field of petrochemical wastewater treatment, in particular to a petrochemical production wastewater treatment device. Background Art

[0002] Petrochemical wastewater refers to wastewater discharged from petrochemical plants. The amount of wastewater is large. In addition to production wastewater, there is also cooling water and other water. The composition of the wastewater is complex. Due to the large number of petrochemical products, the reaction process and unit operations are complex, and the nature of the wastewater is complex and changeable. The content of organic matter in the wastewater, especially hydrocarbons and their derivatives, is high, and it contains a variety of heavy metals. Petrochemical wastewater comes from many sources and has different components. It is closely related to the production process. Therefore, the water quality and quantity of the wastewater are difficult to determine. At present, when treating petrochemical wastewater, demulsifiers are generally poured into the sewage pool to achieve oil-water separation, and the oil scraper is used to scrape off the floating oil on the top.

[0003] However, the traditional petrochemical production wastewater treatment equipment still has certain shortcomings during use: the current equipment generally uses a scraper to scrape the floating oil inside the sewage pool into the floating oil collection pool on one side, but the inner wall of the floating oil collection pool will be attached to a lot of oil due to long-term use, and there are toxic substances in it. The traditional device requires manual operation when carefully cleaning the inner wall of the collection pool, but this has a certain impact on the health of the workers, and the cleaning is time-consuming and labor-intensive.
