FIG. 1 is a schematic diagram of the operation of the preferred embodiment of the present invention;
in the figure: 1. a water tank; 2. a water pump; 3. a filter; 4. a high pressure pump; 5. a first section of film; 6. an interstage pump; 7. a second stage of film; 8. a dosing system; 9. a water producing end; 10. and a concentrated water discharge end.
Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.
As shown in fig. 1, a novel two-stage reverse osmosis system comprises a water tank 1, a water pump 2, a filter 3, a high-pressure pump 4, a first stage membrane 5, an inter-stage pump 6 and a second stage membrane 7 which are sequentially connected by pipelines; the first section membrane 5 and the second section membrane 7 are reverse osmosis membranes, and the water inlet end of the second section membrane 7 is connected with the concentrated water discharge end 9 of the first section membrane 5 through the intersegmental pump 6.
In this embodiment, sewage is pumped out from the water tank 11 through the water pump 22, enters the first section membrane 5 through the filter 33 and the high-pressure pump 44 for treatment, before entering the first section membrane 5, a medicament is added into a pipeline through a medicament adding system to pretreat the sewage, then, a part of concentrated water is discharged from the water producing end 8 of the first section membrane 5, and the other part of concentrated water is pressurized through the interstage pump 6 and enters the second section membrane 7 for treatment.
Specifically, in the present embodiment, the water producing ends 8 are disposed on the first stage membrane 5 and the second stage membrane 7.
In this embodiment, a dosing system is provided between the water pump 2 and the filter 3, and the dosing system can feed a drug into the pipeline.
Specifically, the medicine adding system is filled with medicines, and the added medicines are bactericides, scale inhibitors and the like.
In the present embodiment, the interstage pump 6 is a booster pump.
In conclusion, the utility model discloses set up intersegmental pump 6 between first section membrane 5 and second section membrane 7, the pressure that greatly increased second section membrane 7 operation needs, and then improve the water production efficiency of second section membrane 7 greatly.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
