Description
Technical field
The present invention relates to a kind of water device that produces, especially relate to a kind of novel reverse osmosis sub-prime and produce water device.
Background technology
In existing reverse osmosis design, the product water of 1 grade of reverse osmosis enters system or the water tank of next stage after being and merging together, do further processing if need to enter next stage system, need to process all product water of reverse osmosis.
Now with as the defect of a certain case history explanation prior art, and in new technology explanation for the advantage of this project case introduction new technology.
Certain reverse osmosis system influent quality (water source is tap water, and ultrafiltration is as the pre-treatment of reverse osmosis):
Table one influent quality
This project is produced water water quality requirement; Specific conductivity≤10 μ S/cm
This project is produced the water water yield: 100m
3/ h
According to existing traditional design concept, because the product water conductivity of first-stage reverse osmosis is 30 μ S/cm left and right (in 3 years), cannot reach design load, the product water of first-stage reverse osmosis need all enter after two-pass reverse osmosis is processed and just can reach and design product water water quality requirement, therefore traditional treatment unit all adopts two-stage reverse osmosis system, cause the investment of whole system high, working cost is high, traditional treatment scheme is as shown in Figure 1: pending water is inputted first-stage reverse osmosis device 1 by first-stage reverse osmosis high-pressure pump 3, first-stage reverse osmosis device is made up of one section of reverse osmosis membrane assembly a11 and two sections of reverse osmosis membrane assembly a12, wherein one section of reverse osmosis membrane assembly a11 is made up of the putamina assembly of 15 groups of parallel connections, every group of membrane module is made up of the reverse osmosis membrane of 6 series connection, two sections of reverse osmosis membrane assembly a12 are made up of the putamina assembly of 7 groups of parallel connections, every group of membrane module is made up of the reverse osmosis membrane of 6 series connection.Each membrane module of first-stage reverse osmosis device 1 is connected in parallel to rinse by pipeline and cleans water intaking valve a13 and rinse and clean outlet valve a14, the product water water outlet of one section of reverse osmosis membrane assembly a11 and two sections of reverse osmosis membrane assembly a12 is connected first-stage reverse osmosis and produces water tank 4, first-stage reverse osmosis produces water tank 4 and connects two-pass reverse osmosis high-pressure pump 5, two-pass reverse osmosis high-pressure pump 5 connects second level reverse osmosis apparatus 2, second level reverse osmosis apparatus is made up of one section of reverse osmosis membrane assembly b21 and two sections of reverse osmosis membrane assembly b22, wherein one section of reverse osmosis membrane assembly b21 is made up of the putamina assembly of 10 groups of parallel connections, every group of membrane module is made up of the reverse osmosis membrane of 6 series connection, two sections of reverse osmosis membrane assembly b22 are made up of the putamina assembly of 5 groups of parallel connections, every group of membrane module is made up of the reverse osmosis membrane of 6 series connection.Each membrane module of second level reverse osmosis apparatus 2 is connected in parallel to rinse by pipeline and cleans water intaking valve b23 and rinse and clean outlet valve b24, the water outlet of second level reverse osmosis apparatus 2 connects two-pass reverse osmosis and produces water tank 6, pending water is inputted first-stage reverse osmosis device 1 by first-stage reverse osmosis high-pressure pump 3 and is carried out reverse-osmosis treated, then enter second level reverse osmosis apparatus 2 and carry out reverse-osmosis treated, the water finally obtaining enters two-pass reverse osmosis and produces water tank 6.
