Embodiment 1
[0063] Example 1: Please refer to figure 1 . Adding an intelligent double faucet to the waste water return system, the intelligent faucet can complete the electronic control of other components in the system through the change of its opening / closing state. The pure water outlet of the first reverse osmosis filter element 11a is divided into two channels, one of which is directly connected to the drinking water end of the double faucet, and the other is a pure water return pipeline R for returning the purified water to the front end of the first reverse osmosis filter element 11a; The waste water outlet of the first reverse osmosis filter element 11a is divided into two ways, one way is directly connected to the domestic water end of the double faucet, and the other way is the waste water return pipeline, and the waste water can be returned to the booster pump 12 through the first flow limiting valve 14a. There is a branch on the waste water return line which is the first wast...
Embodiment 2
[0068] Example 2: Please refer to figure 2 . In this embodiment, on the basis of Embodiment 1, a pre-filter 17a is added at the front end of the booster pump 12. The type of the pre-filter 17a can be different forms of PP, different forms of activated carbon, ultrafiltration, nanofiltration and the above materials Composite filter elements, etc., the front outlet water flow rate is <8L / min.
[0069] The user turns on the drinking water faucet (drinking water inlet 131 is connected to the drain outlet 133): the booster pump 12 starts to produce water; Wastewater and pure water are discharged from the drinking water faucet for drinking, and the waste water flows back to the front of the pump through the first flow limiting valve 14a, mixes with the front outlet water, enters the reverse osmosis filter element and filters again, and realizes zero discharge of waste water.
[0070]The user turns on the domestic faucet (the domestic water inlet 132 is connected to the drain 133)...
Embodiment 3
[0073] Example 3: Please refer to image 3 . In this embodiment, on the basis of Embodiment 1, a rear filter element 17b is added to the pure water outlet pipeline of the first reverse osmosis filter element 11a before the return pipeline, and the type of the rear filter element 17b can be activated carbon in different forms.
[0074] The user opens the drinking water faucet (drinking water inlet 131 is connected to the outlet 133): the booster pump 12 starts to start water production; after the tap water flows into the first reverse osmosis filter element 11a, it is divided into one path of pure water and one path of waste water, and the pure water passes through The rear filter element 17b is discharged from the drinking water faucet for drinking, and the waste water flows back to the front of the pump through the first restrictor valve 14a, mixes with the tap water, enters the first reverse osmosis filter element 11a and filters again, and realizes zero discharge of waste w...
