Fig. 3 is reverse osmosis pure wetting system water preparation process flow chart, and process flow includes three steps.
Step A1: first-stage reverse osmosis water pretreatment is handled using the three-stage filtration of preposition softening, is obtained conductivity and is less than
The industrial pure water of 10us/cm.
In the water of source contain a large amount of suspended matter, colloid and soluble high-molecular, they be gathered in film surface can make film by
Pollution;In membrane separating process, due to the continuous transmission of water, it is higher than the concentration of solute in solution in the solute concentration of film surface,
To form the concentration polarization of film;In the water of source also contain many microorganisms and bacterium, they also can degraded films, bacterium, microorganism
Corpse can also be precipitated in solid form, so that film properties is degenerated, the parameters such as temperature, pH value, pressure, contents of residual chlorine of source water it is bad
Change the hydrolysis that can all cause film, oxidation;The film Morphology as caused by solute also results in the permeable speed decline of film；
It is hindered to be reduced in membrane separating process, extends the service life of film, it is necessary to which pretreatment appropriate is carried out to source water.
After the pressurized pump of raw water, into first-stage reverse osmosis water pretreatment, treatment process includes: quartz filter → work
Property carbon filter → automatical softener → cartridge filter four processes.
(1) quartz filter treatment process, for suspended solid, generally before reverse osmosis, with sand filtration or multimedium mistake
Filter can be removed sufficiently;The small suspended particulate of partial size and colloid are easiest to cause the pollution of film, the particle very little and band of colloid
There is charge, be difficult to remove with filter method, usually plus the method for flocculating agent makes colloidal particle be condensed into micelle, then passes through quartz sand
This micelle is filtered just to be easy to remove；
(2) charcoal filter treatment process, main function are the organic matters partly gone in water removal, are adsorbed contained in water
The substances such as chlorine residue, peculiar smell, pesticide and the un-cleared colloid of sand filtration；
(3) water softener treatment process, to prevent calcium ions and magnesium ions fouling, add water softener to its in advance remove, while remove iron,
The microelements such as manganese；
(4) cartridge filter treatment process selects the PP filtering element (cartridge) with aperture for 5um, and the last ring before reverse osmosis membrane is arranged in
It saves, various impurity of all partial sizes in 5um or more in the water that can shut off.
First-stage reverse osmosis water pretreatment specific steps are as follows:
1, the manual multiple-way valve knob of quartz filter and charcoal filter rotates to running position；
2, more medium filter backwash carries out according to the following steps；
(1) RO system switching knob rotates to stop position；
(2) manual multiple-way valve knob rotates to backwash position；
(3) startup power supply rotary switch, dextrorotation raw water pump manual switch-starting raw water pump, after backwash 10 minutes, more manually
Road valve knob, which rotates to, just washes position；
(4) raw water pump manual knob switch is closed after just washing 10 minutes；
(5) after backwash finishes, manual multiple-way valve knob is rotated to running position；
3, water softener is just being washed by backwash-, and-inhale salt and wash slowly-fills the water progress；
(1) power switch is opened, system switching is in close state, and manual heads is switched to the position of backwash；
(2) then right rotation, raw water pump manual switch open raw water pump and start backwash, after about 10 minutes, manual switching
To the position just washed, starts just to wash, be analogized below with secondary；
(3) until seeing that salt box does not have water when inhaling salt；
(4) water not allowed to overflow water preferably when filling the water；
(5) manual Vavle switching is produced water state to normal after softening regeneration.
Raw water can get the industrial pure water that conductivity is less than 10us/cm after first-stage reverse osmosis pre-processes.
Step A2: two-pass reverse osmosis water process, using membrane technology, at RO reverse osmosis equipment, deionization mixed bed
Reason obtains the industrial pure water that conductivity is less than 3us/cm.
The obtained industrial pure water of first-stage reverse osmosis water pretreatment is after high-pressure pump, into two-pass reverse osmosis water process work
Skill, treatment process include: second level RO reverse osmosis equipment → deionization mixed bed → two-pass reverse osmosis pure water tank, obtain conductivity
Industrial pure water less than 3us/cm.
RO anti-penetration wastewater disposal is at room temperature, using membrane technology, will to be contained using physical method without phase-change
Salt water supply carries out desalination, purification process.According to the requirement of water quality and user, one section of level-one, level-one multistage, multistage multistage can be used
Configuration mode form reverse osmosis water treatment system.The rate of recovery of counter-infiltration system will (total dissolubility be solid depending on TDS in the water of source
Body) concentration, TDS is 100mg/L in a highest wisdom source water, then the rate of recovery of water can be to 90%, if TDS is greater than 260mg/ in the water of source
L, then for same amount of membrane component, the rate of recovery of water is only 50%；Due in water there are also other ionic impurities presence,
Also influence whether that the rate of recovery of water, the rate of recovery highest of Gu Shui do not exceed 75%.
Two-pass reverse osmosis Pure water preparation step specific steps are as follows:
1, startup power supply switching knob power supply indicator is bright, indicates to turn on the power switch；
2, start RO system rotary switch, such as meet service condition, then raw water pump is automatically opened with film scouring electromagnetic valve, is opened
Machine film rinses, and rinses after 90s, system is transferred to production water state automatically；System enters automatic mode, and water is full, water shortage automatic start-stop.
3, reverse osmosis main shut-down system is first shut off RO system rotary switch, knob is turned off the power switch after one minute.
After two-pass reverse osmosis is handled, the industrial pure water that conductivity is less than 3us/cm can get.
Step A3: carrying out ultraviolet sterilization, obtains the final industrial pure water for meeting and washing shield series of products.
After two-pass reverse osmosis is handled, industrial pure water kills harmful microorganism using ultraviolet light again through ultraviolet sterilization,
The bacterium in pure water is removed, the technical pure water purification for meeting and washing shield series of products is finally obtained.
Although disclosed herein embodiment it is as above, the content is only to facilitate understanding the present invention and adopting
Embodiment is not intended to limit the invention.Any those skilled in the art to which this invention pertains are not departing from this
Under the premise of the disclosed spirit and scope of invention, any modification and change can be made in the implementing form and in details,
But scope of patent protection of the invention, still should be subject to the scope of the claims as defined in the appended claims.

6. pure water preparation process flow according to claim 2, it is characterised in that:
The two-pass reverse osmosis water treatment technology includes: that second level RO reverse osmosis equipment → deionization mixed bed → two-pass reverse osmosis is pure
Water tank；For the pure water after first-stage reverse osmosis water pretreatment, water conductivity is less than 3us/cm.
7. the pure water preparation process flow according to claim 2 or 6, it is characterised in that:
The second level RO anti-penetration wastewater disposal technique application membrane technology, using physical method without phase-change by saliferous water supply into
Row desalination, purification process；The rate of recovery of the counter-infiltration system depends on the concentration of TDS (total dissolved solid) in the water of source.
