Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
A kind of high-recovery counter-infiltration system, including by being set gradually on running water inlet to the pipeline between pure water outlet
Front filtration system 9, centre RO membrane filters 5 and postpositive disposal filtration system 1, front filtration system and centre RO membrane filters it
Between pipeline be equipped with inlet valve 10 and booster pump 7, set on the pipeline between intermediate RO membrane filters and postpositive disposal filtration system
There are pure water outlet pressure switch 2 and pure water pressurized tank 14.
Equipped with first order ultrafiltration automatic backwash system, it is included on the pipeline between booster pump and RO membrane filters and is connected with
Branch 8 is backwashed, the other end for backwashing branch connects with the backwash port of first order ultrafiltration, and the sewage of first order ultrafiltration goes out
Purge valve 6 is housed equipped with flow switch 16, backwash branch road on mouth pipe；
Equipped with concentrated water recycling system, including water tank 13, the water inlet of water tank passes through recovery tube 3 and RO membrane filters
Concentrated water discharge pipe be connected, equipped with waste water ratio valve 4 on recovery tube, the water outlet of water tank by return pipe 12 and be arranged on into
Pipeline between water valve and booster pump connects, and check valve 11 is housed on return pipe.
The outlet side of concentrated water discharge pipe is equipped with concentrated water dump valve.
Water tank is equipped with four point position control floating-ball level switch 15.
The specific technical solution of the present invention described further below, in order to which those skilled in the art is further understood that
The present invention, without forming the limitation to its right.
As shown in drawings：
Postpositive disposal filtration system 1, pure water outlet pressure switch 2, recovery tube 3, waste water ratio valve 4, centre RO membrane filters 5,
Purge valve 6, booster pump 7, backwash branch 8, front filtration system 9, inlet valve 10, check valve 11, return pipe 12, water tank
13rd, pure water pressurized tank 14, four point position control floating-ball level switch 15, flow switch 16.
This system includes automatic backwash system, the concentrated water recycling system of first order pretreatment ultra-filtration element, concentrated water
Recycling system includes rate of recovery control system and concentrated water is formed using system three parts.
