In order to control the ratio of the amount of concentrated water introduced into the third water pipe 7 from the concentrated water outlet of the RO reverse osmosis apparatus 4 discharged through the fifth water pipe 9 to the amount of concentrated water introduced into the third water pipe from the concentrated water outlet of the RO reverse osmosis apparatus 4 and returned to the RO reverse osmosis apparatus 4 again through the fourth water pipe 8 and the second water pipe 6, a first flow meter 12 and a first valve 13 are provided on the fourth water pipe 8, and a second flow meter 14 and a second valve 15 are provided on the fifth water pipe 9. The discharge rate of the fifth water pipe 9 and the flow rate of the concentrated water back to the RO reverse osmosis device 4 through the fourth water pipe 8 can be adjusted by adjusting the first valve 13 and the second valve 15, and the discharge rate of the concentrated water through the fifth water pipe 9 and the flow rate of the concentrated water back to the RO reverse osmosis device 4 through the fourth water pipe 8 can be observed by observing the first flowmeter 12 and the second flowmeter 14. So that the ratio of the amount of the concentrate discharged as the wastewater to the amount of the concentrate recirculated to the RO reverse osmosis apparatus 4 can be controlled and grasped.
In order to facilitate the maintenance or replacement of the high-pressure pump 2 when the high-pressure pump 2 fails, a third valve 16 is provided on the first water pipe 5. When the high-pressure pump 2 is overhauled or replaced, the water in the raw water tank cannot flow out from the end, used for being connected with the high-pressure pump 2, of the first water pipe 5 only by closing the third valve 16, and the water in the RO reverse osmosis device 4 cannot flow out from the end, used for being connected with the high-pressure pump 2, of the second water pipe 6 because the first backflow preventer 10 is located between the connecting position of the fourth water pipe 8 and the second water pipe 6 and the high-pressure pump 2.

Then tap water enters the first water pipe from the outlet of the cartridge filter 1, the tap water entering the first water pipe is pressurized by the high-pressure pump 2 until the tap water meets the reverse osmosis pressure and then enters the RO reverse osmosis device 4 through the second water pipe, part of pure water is filtered out by the RO reverse osmosis device 4, the pure water is discharged from the pure water outlet of the RO reverse osmosis device 4, the concentrated water after the pure water is filtered out enters the third water pipe 7 from the concentrated water outlet of the RO reverse osmosis device 4, one part of the concentrated water entering the third water pipe 7 is discharged from the fifth water pipe 9, the other part of the concentrated water is pressurized by the circulating pump 3 until the tap water meets the reverse osmosis pressure of the RO reverse osmosis device 4 and then enters the RO reverse osmosis device 4 again through the fourth water pipe 8 and the second water pipe 6 for reverse osmosis filtration again. The dense water that gets into fourth water pipe 8 from RO reverse osmosis unit 4's dense water export through third water pipe 7 still has great pressure, and circulating pump 3 only needs can make the dense water that gets into fourth water pipe 8 reach and satisfy RO reverse osmosis unit 4's reverse osmosis pressure after carrying out a small amount of pressure boost to dense water, need not decompress dense water and retrieve behind the former water tank through high-pressure pump 2 repressurization, can reduce energy consumption, effectively utilize the energy. When the high pressure pump 2 malfunctions, the first backflow preventer 10 can prevent the concentrated water flowing into the second water pipe 6 through the fourth water pipe 8 from flowing back to the raw water tank. When circulating pump 3 breaks down, second backflow preventer 11 can prevent that the running water from directly draining through second water pipe 6, fourth water pipe 8, third water pipe 7 and fifth water pipe 9, prevents that the running water from not filtering through reverse osmosis membrane just being drained as waste water.
