Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a pretreatment device for oily wastewater from car washes. Background Technology

[0002] Oily wastewater from car washes refers to wastewater containing grease, oil, and other pollutants generated during the vehicle washing process.

[0003] When common oily wastewater enters the treatment equipment, it is treated by separating into layers after a long period of stillness due to the density difference and chemical properties of oil and water. This treatment method takes a long time. When emulsifiers are used to accelerate the treatment, directly pouring in the emulsifier will result in uneven distribution of the emulsifier, which cannot be added in multiple layers. The emulsifier is concentrated in one area, which prolongs the reaction time.

[0004] Now, a pretreatment device for oily wastewater from car washes is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a pretreatment device for oily wastewater from car washes, in order to solve the problem mentioned in the background art that the emulsifier does not have the ability to be added at multiple levels.
