Description

A car washing device with purified water and concentrated water

Technical field:

The invention belongs to the field of purified water treatment, and in particular relates to a car washing device with purified water and concentrated water.

Background technique:

Water purification is the process of removing rust, sediment, residual chlorine, organic matter, harmful heavy metal ions, bacteria, viruses, etc. Obviously, if the physical filtration method is used in the whole process of water purification, it will not generate or add any new substances in the water, and it will not change the properties of the water, so it is the safest method.

At present, water purification and sewage treatment technologies can be roughly classified into three categories: physical methods (precipitation, floating, flotation, centrifugal separation, filtration, evaporation, crystallization, freezing, magnetization, electrolysis, reverse osmosis, etc.), chemical methods (coagulation, neutralization, oxidation, reduction, displacement, ion exchange, electrodialysis, etc.), biological methods (aerobic biological treatment and anaerobic biological treatment).

Through on-the-spot investigation, the wastewater produced in the water treatment process of the water purification plant accounts for about 4%-7% of the total treated water volume of the water plant, mainly including the sludge discharge water from the sedimentation tank, the clarification tank and the backwash water of the filter tank. Slurry water accounts for about 42.5% of the water plant's own water consumption (water plant's own water consumption for one row of muddy water + filter backwash water + other water use); the water delivery station sends about 450 barrels of water to users every day, a barrel of 18.9L, every day To drink about 8.505 tons, according to the survey data, the water purification plant purifies according to the ratio of 1:1. Every time it is purified into a bucket of pure water, 18.9L of water is wasted, so half of the water is wasted every day. And manual car washing generally requires 50-80 liters of water per car. According to the degree of dirtiness of the car, it needs about 120 liters for serious ones! That is to say, 1 ton of water can wash about 10 cars. The car wash basically uses tap water to wash the car directly, and the cost is relatively high. Car wash shops wash about 50 cars a day on average, and the number will increase during holidays. 1 ton of water can wash about 8 cars, so the daily water consumption of the car wash shop is about 6 tons, and 200 tons of tap water is used in a month.

The wastewater produced by the water purification plant in the water treatment process is directly discharged, resulting in a waste of water resources. How to recycle the wastewater is an urgent problem to be solved.

The utility model aims to recycle the waste water generated in the water treatment process and apply it to the car washing industry, save water resources and reduce costs. The generated wastewater is treated to meet application standards and recycled for use in car washes.
