Background technique

Population growth, economic development and over-exploitation of resources have caused great pressure on the environment; in recent years, water resources have been severely lacking and water pollution has been increasing. With the improvement of people's living standards, the number of cars owned by units and families is also increasing, which will inevitably lead to a large consumption of car wash water. According to statistics, 0.04-0.10m ³ of water is needed to wash a small car, and the water used for car washing in a large and medium-sized city can be used by 60,000 people for one year. This shows the consumption of water for car washing.

In addition, the management of the car washing industry in many cities is not standardized. The random discharge of car washing water causes cross-flow of sewage, which seriously affects the appearance of the city and the living environment of citizens.

Most of the existing technologies use a number of sedimentation tanks dug on the ground to discharge the car washing wastewater into the sedimentation tank and then discharge it from the sedimentation tank. The car washing wastewater contains a large number of pollutants such as oil, organic matter, anionic surfactants, etc. If it is directly discharged, it is bound to cause pollution to the water body.
