Specific embodiment
As shown in Figure 1, the utility model includes the pretreatment unit 1 for carrying out primary filtration to raw water, by locating in advance
The raw water of reason enters counter-infiltration system by the first conduit 12.Counter-infiltration system includes first-stage reverse osmosis pump 2, first-stage reverse osmosis film
3, two-pass reverse osmosis pump 4 and two-pass reverse osmosis film 5, first-stage reverse osmosis pump between 2 and first-stage reverse osmosis film 3 by the second conduit 13
It is connected, is connected between first-stage reverse osmosis film 3 and two-pass reverse osmosis pump 4 by third conduit 14, two-pass reverse osmosis pump 4 and second level reverse osmosis
It is connected between permeable membrane 5 by the 4th conduit 15.Water into counter-infiltration system is first pressed to form high pressure water by first-stage reverse osmosis pump 2,
Then primary reverse osmosis water is formed by the filtering of first-stage reverse osmosis film 3, is then finally passed through by 4 pressurization of two-pass reverse osmosis pump again
The filtering of two-pass reverse osmosis film 5 forms two-pass reverse osmosis water, and two-pass reverse osmosis water is purified water.
