Embodiment 1

[0047]As shown in FIG. 1, the present invention mainly includes a pressure limiting valve 1, an ultrafiltration water purifier 4, and an anti-oxidative reverse osmosis unit 10. The pressure limiting valve 1 has a water cutoff function and is installed at the front end of the system, and is connected with the water inlet pipe. 40 is connected, and its water outlet is water pipe A2. On the water pipe A2, a first pressure switch 22 and a second check valve 23 are connected in series in sequence, and a first three-way 3 is also installed at the outlet end of the second check valve 23. One of the first three-way 3 The outlet is communicated with the ultrafiltration water purifier 4 , and the other outlet is connected with the concentrated water outlet of the anti-oxidation reverse osmosis unit 10 through a communication pipe 30 . The ultrafiltration water purifier 4 is respectively connected with the flush valve 4.1 and the drain valve 4.2, and its opening and closing can be contro...

Embodiment 2

[0055] As shown in Figure 2, this embodiment is basically the same as the first embodiment, the difference is that the anti-oxidation reverse osmosis unit 10 with a large water flow rate is selected to meet the requirements of users for immediate use, so it is not necessary to equip a water storage system, and the anti-oxidation reverse osmosis unit 10 is not equipped with a water storage system. The outlet end of the permeation unit 10 is connected to the pure water tap 17 through the water pipe D11, the first check valve 12, and the second pressure switch 32 of the water pipe F16. When the user uses water, after opening the pure faucet 17, the water pressure of the water pipe F16 drops, the pressure switch 32 gives a signal, and starts the water pump 8; Turn off the water pump.

Embodiment 3

[0057] As shown in FIG. 3 , this embodiment is basically the same as the first embodiment, the difference is that a sterile water tank 18 is used to replace the pressure barrel 13 and the rear charcoal barrel 15 in the first embodiment. Described aseptic water tank 18 is the improved substitute product of pressure barrel 13, it is characterized in that it does not need to configure rear activated carbon, if it is installed on the top of pure water tap 17, it can flow out water; Provide power source. As shown in the figure, the sterile water tank 18 in this embodiment is located below the pure water faucet 17, and a power source is required to supply water to the outside. The double-head dual-purpose pump 20 is arranged on the water pipe C9 that communicates with the second three-way 6, the water outlet of the pump filter head 20.1 is placed on the water pipe C9, and an outlet of the water delivery head 20.2 is communicated through the water pipe G19 The pure water tap 17 has ...

Abstract

The present invention is household water treating method and system with antioxidant reverse osmosis film. In the household water pipeline, are set successively a pressure limiting valve to limit the water pressure, a ultrafiltering water purifier to treat water initially to obtain sanitary water, and a antioxidant reverse osmosis unit with reverse osmosis film to treat partial water into pure water, with the concentrated water flowing out the reverse osmosis film being returned to the sanitary water treating unit. The present invention has simple water pre-treating process, low system operation pressure, less leakage possibility, low running cost and other advantages.

Description

【Technical field】 [0001] The invention relates to the field of water treatment and purification, in particular to a treatment method for household water purification by using an anti-oxidation reverse osmosis membrane and a system designed by applying the method. 【Background technique】 [0002] The household pure water treatment system in the prior art is mainly composed of three parts: water pretreatment part, reverse osmosis filtration part and pure water storage part. The reverse osmosis membrane is the core of the entire pure water filtration system. Generally, the membrane pore size of the reverse osmosis membrane is very small, which can filter out salts and all other harmful substances in the water, but this filtration requires a certain amount of kinetic energy. Under the premise that the tap water pressure is not enough, a pressure source - a micro-diaphragm pump must be equipped before the reverse osmosis membrane. The membrane pump and the reverse osmosis membrane...
