Description

Excellent living building water treatment station

technical field

The utility model relates to a water purification treatment system, in particular to an excellent active building water treatment station for pure water treatment.

Background technique

With the improvement of living standards, people's requirements for water are no longer satisfied with the way of purifying ordinary water and drinking water after boiling. Pure water has entered the homes of ordinary people. There are roughly two types of purified water available: one is bottled water, which includes a 500-milliliter bottle of purified water, and bottled water that uses a repurposed water dispenser. The other is to supply pure water directly from the water plant and send it to every household through a special pure water pipeline. The price of small bottles of water in the former is more expensive, and it is difficult for ordinary people to afford it for a long time. The price of bottled water is relatively cheap, but it takes a week for the average family to use up a bucket of water, and the inspection by the health department shows that fresh purified water is replaced. After three days, the bacteria in the air will grow and multiply in the barrel and exceed the standard, so there is a problem of secondary pollution; the latter's pipeline pure water is relatively cheap in terms of comprehensive cost accounting, but the purchase and installation of equipment and pipeline laying Such advanced projects require high investment, and secondary pollution also exists in some environments, which is not compatible with my country's national conditions at present.

Utility model content

The purpose of the utility model is to solve the above-mentioned problems, and provide a low-investment, convenient installation and use, and no secondary pollution, an excellent living building water treatment station for pure water treatment.

In order to achieve the above purpose, the technical solution of the utility model is: a kind of high-quality active building water treatment station for pure water treatment, which consists of a magnetic water processor, a nanofiltration membrane filter, a pre-stage ultraviolet sterilizer, a water storage tank and The post-stage ultraviolet sterilizer is sequentially connected by pipelines, the water source supply end is connected to the magnetic water processor, and the main drinking water pipe for users is drawn from the post-stage ultraviolet sterilizer.

Since the first stage of the building water treatment station of the utility model adopts a super-strong magnetic water processor, the super-high-strength magnetic field generated by the permanent magnet destroys the environment on which bacteria and algae live, and the dissolved oxygen is formed under the action of the super-high-strength magnetic field Some substances such as O ₃ , H ₂ O ₂ , etc. have strong lethality to bacteria and algae, which can kill bacteria and algae and activate water. The second stage uses ultrafiltration or nanofiltration of high-tech materials (nanofiltration membrane), which can remove dissolved salts, colloids, bacteria, macromolecular organic matter and other smaller viruses, impurities, and particles that endanger human health. The nanofiltration membrane retains the life elements needed by the human body in the water molecules under the same condition of removing harmful substances. The water produced can achieve the taste of pure water and trace elements of mineral water. The third level uses ultraviolet disinfection. Ultraviolet rays with characteristic wavelengths (250-295nm) can produce photochemical reactions with DAN, the life center of microorganisms, in an instant, causing the microorganisms to die or lose the ability to continue to survive and reproduce. This method has high disinfection and sterilization capabilities, and ultraviolet rays can remove volatile chlorinated hydrocarbons. The mechanism of UV damage to organic matter is that under the irradiation of ultraviolet rays, the chemical chain of organic matter is broken and decomposed. The safety (99.99%) is good, and no toxic by-products will be formed. The fourth level uses high-power ultraviolet light to circulate and re-sterilize the water in the water storage tank, completely solving the problem of secondary pollution of the water storage tank, and at the same time increasing the flow rate to meet the water requirements of residents. The final result is water that meets the national high-quality drinking water standards and can be drunk directly.

Compared with the existing technology, the utility model has relatively small investment and low cost, and is convenient to drink, and can be directly drunk once the drinking water tap is turned on, which is hygienic and economical, and is very suitable for the existing national conditions of our country.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

Please refer to Fig. 1, the utility model is used for the excellent living type building water treatment station of pure water treatment, is made up of magnetic water processor 3, nanofiltration membrane filter 4, pre-stage ultraviolet sterilizer 5, water storage tank 7 and post-stage ultraviolet ray Disinfector 9 is connected successively by pipelines, and the water source supply end is connected with described magnetic water processor 3, and user drinking water main pipe 17 is then drawn from described post-stage ultraviolet sterilizer 9. In Fig. 1, an ozone sterilizer is provided between the pre-stage ultraviolet sterilizer 5 and the water storage tank 7, and certainly an ozone sterilizer may not be provided.

Referring to Fig. 2, the ozone sterilizer arranged between the front-level ultraviolet sterilizer and the water storage tank is composed of an ozone sterilizer 14 and a gas-water mixer 12 connected to each other, wherein the gas-water mixer 12 is arranged on the front On the pipeline between the grade ultraviolet sterilizer 5 and the water storage tank 7. The side wall of the water storage tank 7 is respectively provided with an upper limit liquid level controller 18, an upper liquid level controller 19, a middle liquid level controller 21 and a lower liquid level controller 20 from top to bottom. An overflow port is opened above the device 18 and an air filter 8 is connected downwards through a pipeline, and a booster pump 1, an electronic flow meter 16 and a solenoid valve 2 are arranged in sequence at the water source supply end.

The building water treatment station is provided with a control device for automatically controlling water supply, and the control device can be a PLC or a computer.
