Background

The automatic car washing equipment is a machine which can realize the work of automatically cleaning, waxing, air drying and cleaning wheel rims and the like by setting related programs through a computer. When the existing automatic car washing equipment works, the equipment identifies the license plate of a vehicle to be washed, records the license plate, and then pulls the vehicle through a conveying chain, so that the vehicle is washed in the car washing equipment.

With the continuous development of national economy and the improvement of the living standard of people in China, automobiles also enter the families of common people, and the automobile protection in China is increased year by year, thereby bringing about the development of the automobile washing industry. By the end of 2014, the motor vehicles in China are kept in 2 hundred million, 6 thousand and more than ten thousand according to the statistics of the national authority departments, wherein the automobile keeping quantity is as follows: about 1.6 million cars. At present, most of the carwashes in China adopt the traditional water washing method, which not only causes great water resource waste, but also brings about serious environmental pollution problem. The serious waste of water resources and the increasing shortage of water resources have become a common problem for all mankind.

The aspect of water waste: each car is washed twice a week, 50 kilograms of water are used for each car, and 100 kilograms of water are used for each car; 16000 million cars will consume 8.34 million square waters, corresponding to the storage capacity of 58.5 West lakes. If the recycling rate is 70 percent, the method is equivalent to reconstructing 41 West lakes. And (3) environmental pollution: the LAS content of the car washing wastewater is between 5mg/1 and 30mg/l only by the LAS, the average value is 17.5mg/l, and the amount of LAS net pollutants is: 14595 tons of water are diluted to the content of national second-class emission standard: lmg/l will use up the capacity of 5 strait reservoirs (strait reservoir capacity: 30 hundred million cubic). The water capacity of 1043 West lakes was used.

Aiming at the current situation of the current car washing water industry, the state has paid high attention and has issued relevant policies, and the national development committee takes the car washing circulating water equipment as an environmental protection product catalog encouraging development as early as 2007. Can prove the high importance of the country for remedying the problem of wasting water in car washing. Water-saving management regulations and policy legislation have been continuously provided in provincial cities and economic developed cities in China to strengthen related regulations and policy legislation of car washing water management, and the waste heat tide of 'regulation of car washing water waste phenomenon' is raised in the national range. The people in various regions respond strongly to the action, and express the support for the overall action in different actions and modes. The phenomenon that water resources are wasted in car washing yards is regulated only slowly, and the situation is highly agreed by governments and the national people all over the country.

The Chinese invention patent with the application number of 201410658700.X discloses water filtering and circulating equipment in a common car washing shop and an automatic car washing system, wherein a filter box is arranged right below the bottom of a steel lattice for parking vehicles in the automatic car washing equipment or a common car washing site, and a layer of filter material layer is fully paved at the bottom of the filter box and is used for filtering and treating sewage after car washing. The size of the filter box of the filter equipment is consistent with the size of the plane of the steel lattice floor on the square of the filter box. The distance between the filter box and the bottom of the steel lattice is 30 cm. A water storage tank is arranged under the filter tank, and the size of the water storage tank is the same as that of the plane of the filter tank. The bottom of the filter box is of a net structure with a steel lattice structure, and the four corners of the filter box are respectively connected with a drain pipe at the edge above the filtering material in the filter box. Several rows of oscillating high-pressure nozzles are arranged right above the filtering material. The novel car washer is simple in structure, convenient to obtain materials, low in manufacturing cost and capable of saving 90% of car washing water when being applied to car washing equipment. However, the filtration mode of the device is too single to effectively filter and purify the wastewater to be treated, and further improvement is needed.
