Description

A system for collecting and treating roof rainwater for self-service vehicle washing

technical field

The utility model relates to a water resource reuse technology, and more particularly relates to a system for collecting and treating roof rainwater for self-service vehicle cleaning.

Background technique

With the rapid development of the city, the hardened area continues to increase, and the direct drainage of rainwater has caused huge waste and increased the burden of urban drainage. The concept of "sponge city" has put forward new requirements for the source control and local consumption of urban rainwater. The quality of rainwater on the roof is relatively good, and it can meet the reuse standard for municipal miscellaneous purposes after simple treatment. However, at this stage, most of the rainwater from the roof is directly discharged to the surrounding roads or green areas, and then discharged into the river through the rainwater pipe network. The collection and utilization have not been realized basically. The economic value of replacing tap water is low, and it is difficult to obtain reused power.

For example, existing urban roof rainwater collection and utilization is generally to collect roof rainwater through rainwater pipes and store it in rain-collecting bottles. However, it has the disadvantages of small amount of collection, basically no treatment measures, poor water quality and inconvenient reuse.

Existing car washing facilities are generally automatic car washing machines with a width of 2 to 3 meters, a length of 8 to 10 meters, and a height of 2 to 3 meters. Brushing rims, automatic spraying bright wax and other functions, and generally use reclaimed water or tap water for car washing. It also has many inconveniences or shortcoming. For example, the high cost of equipment leads to high cost of car washing; the car wash room occupies a large area; the water source is not easy to obtain, and the cost of tap water is high; the high-pressure water gun produces a large amount of water, and the car wash consumes more water;

In today's increasingly tense and precious water resources, making full use of roof rainwater has important social and economic significance.
