Car-washing water recycling system

Abstract

The invention discloses a car-washing water recycling system, and relates to the technical field of water resource recycling. Car-washing water passes through a ladder-shaped guide plate on the bottom of a car-washing room, flows into a water-outlet water tank through a transition water tank, and carries out multi-stage sand settling in a flowing process, so that settling sand can be removed at regular intervals, and therefore, car-washing sewage smoothly flows; a sewage pump pumps the sewage into a settling tank from the water-outlet water tank, and the sewage, carries out a coagulant and a neutralizer make a chemical reaction, so that liquid-solid phase separation is realized in the settling tank; settled solid is collected into a solid recycling tank, and the recycling tank is cleared at regular intervals; water settled by the settling tank is pumped into the filter tank through a pump, the water flows to the bottom from the top of the filter tank, and impurities and particles which are not removed are blocked by quartz sand, and the filtered water flows into a storage tank; equipment carries out self-cleaning in a backflow mode, the water reaches the top from the bottom of the filter tank, and reflux water flows into the settling tank to carry out settling; and in the storage tank, the water is sucked in through a pump to start a car washing process; and if water amount is not enough, external tap water is supplemented.

Description

technical field [0001] The invention relates to the technical field of water resource recycling and reuse, in particular to a car washing water recycling and recycling system for recycling and reusing water after car washing in an urban car washing room. Background technique [0002] Water, the source of all living things on earth. Without water, humans, animals, plants, etc. cannot survive. Especially in modern society, with the rapid development of industry and agriculture, the demand for water is increasing, and the increasing temperature of the earth is increasing. It increases the difficulty of using water. [0003] People living in the city are due to the expansion of the city, and automobiles have become a means of transportation for people to go out. Passages exposed to the sun and rain make travelers often clean the used vehicles to keep the vehicles clean and tidy. However, all of this is inseparable from the use of water. In the existing car washing industry, t...

Problems solved by technology

In the existing car washing industry, the water after car washing and the cleaning fluid and sediment mixed in the water are all treated as waste water and discharged into the sewer. The waste water after car washing is a very large source of pollution. Water is wasted in vain, which increases the demand for water resources; moreover, the washed sediment can easily block the sewers, and the cleaning fluid in the water will cause environmental pollution, all of which are incompatible with a city that is actively developing
