Efficient water-saving vehicle washing system and method for vehicle coated with polymer nano-alloy paint

Abstract

The invention relates to the field of vehicle washing, in particular to an efficient water-saving vehicle washing system and method for a polymer nano-alloy coating coated vehicle. The system comprises a whole vehicle, a sewage pretreatment mechanism, a sewage treatment mechanism and a vehicle washing room, wherein the surface of the whole vehicle is coated with polymer nano-alloy paint in advance; the sewage pretreatment mechanism comprises a precipitation water tank, a bag filter and a sewage pool, a first water pump is arranged in the precipitation water tank, and a second water pump is arranged in the sewage pool; the sewage treatment mechanism comprises a film biological filtration water tank and a clear water tank, a dosing tank and a No.3 water pump are arranged in the film biological filtration water tank, and a medicament added into the dosing tank is a coagulant; a deodorant is added into the clear water tank, and the clear water tank is provided with a fourth water pump; according to the scheme, vehicle washing water resources can be comprehensively and effectively recycled; the repeated utilization rate of vehicle washing water resources reaches 85% or above; according to the invention, the sewage is recycled all year round without changing water through the treatment of a sludge reflux process, so that the environmental protection requirement of near-zero discharge of the sewage is met.

Description

technical field [0001] The invention relates to the field of car washing, in particular to a high-efficiency water-saving car washing system and method for coating vehicles with polymer nano-alloy paint. Background technique [0002] The coexistence of extreme shortage and serious waste is one of the main problems existing in my country's water resources at this stage; the waste of water resources is especially prominent in the car wash industry. On the one hand, there is a shortage of water resources, on the other hand, there is widespread water waste and low utilization There are several main reasons for this situation: First, people lack sufficient awareness of the importance, urgency and long-term nature of water conservation. For a long time, people have regarded water as an inexhaustible and renewable resource, and water has become the cheapest resource; because people lack scientific and correct water-saving concepts, they do not put water-saving in a prominent positio...
