[0002] With the increase in the number of cars, the market demand for car washers is increasing. Car washers not only improve the efficiency of car washing, but also provide users with convenient services. However, the sewage generated by traditional car washers during the car washing process is often discharged directly, which not only wastes water resources, but also may pollute the environment. At present, some car wash shops use sedimentation tanks or simple filtering devices to preliminarily treat car wash sewage, but the treatment effect is limited and it is difficult to meet the sewage treatment needs of car washers when they are working in large quantities. In addition, during the car washing process, when there is too much sediment, it is easy to cause the filter to be blocked, affecting the flow of sewage and the efficiency of car washing. Therefore, it is necessary to make improvements. Utility Model Content
