Technical field
This utility model belongs to application field of water treatment, relates to industrial large-sized reverse osmosis membrane apparatus operation maintenance and pollutes control
System, especially a kind of Industrial reverse osmosis film device pollution situation judges online, completes pollutants identification and pollutant cleaning program
The device judged.
Background technology
Reverse osmosis membrane apparatus is a kind of wide variety of feed separation, solution purification method.Especially in desalinization, hardship
The softening of desalination, bitter, surface water treatment, Industrial Wastewater Treatment, urban sewage recycling process, industrial pure water process, work
The fields such as industry material concentration are widely used.Typically, this system selects the membrane component of rolled structure, uses single hop, multistage in design
Or multistage system configuration.In order to ensure the properly functioning of system, coagulant precipitation, more medium filter, activity typically can be selected
Carbon filter, ultrafiltration, cartridge filter, disinfection system etc. carry out pretreatment, and its technique core is to prevent reverse osmosis membrane or nanofiltration
There is serious fouling membrane in film.Even if but using above-mentioned technique or equipment, reverse osmosis membrane system or nanofiltration membrane system because originally
The highly enriched characteristic of body, still can polluting by the pollutant in water body.Therefore in reverse osmosis membrane or the reality of nanofiltration membrane system
Border application in, prevention and cure of pollution remain its heavy among.
In the pollution problem of general reverse osmosis membrane, the most all can relate to two big classes: the first kind is reversible fouling membrane shape
Condition, such as, retain for ion component due to reverse osmosis membrane, and forms concentration polarization layer in the boundary region on film surface.This
Pollution type generally can be promoted by surface velocity, the hydromechanical condition optimizing of degradation or run and control to come under the response rate
Controlled or improved；Equations of The Second Kind is irreversible fouling membrane situation, such as because of film surface electric charge or the Van der Waals of molecule
Power and form film surface contamination deposition etc., this pollution situation is generally all the most different owing to the condition of water quality changes.Reverse osmosis membrane
The a lot of preposition processing equipment that device is equipped with is provided to cut down the formation of this kind of pollution.This two classes pollution situation is difficult to strict district
Separate, it is common that synergism.
A lot of scholar and the engineering of water treatment teacher pollution situation all for reverse osmosis membrane is had to give the biggest attention at present,
And studied for conditions associated and thought deeply.Chinese Patent Application No. 201110424602.6 discloses a kind of reverse osmosis membrane
The decision method that microorganism is polluted.The method utilize plate count away from, use Petrifilm paper disk method accurately, quickly examine

Device in running it is difficult to ensure that only by the other pollution of unitary class, be the most all compound pollution.And operator
Concerned about content for reverse osmosis membrane apparatus more concentrates on operational factor and clean-in-place recovers.Said method is used relatively to be difficult to reality
These targets existing.
Should be used for from actual at present, fouling membrane determination methods based on on-the-spot running gear is concentrated mainly on two kinds: one
It is with on-the-spot large reverse osmosis device as references object, is judged pollution tendencies and the pollution of film by the service data of device
Situation.Solve once the mode occurring fouling membrane just to use concentrated chemical to clean, or need on-the-spot reality 4 cun or 8
Very little membrane component carries out dismantling, having dissected pollutants identification and the judgement of pollutant cleaning program.This method has some shortcomings:
Cleaning every time or pollute and all have to stop normally producing water when judging, reduce system obtains water rate；Meanwhile, to dismantle every time
Mounted membrane component in system, delivers to Large components Special experimental room and detects, spend costly.
Another kind is that scene installs the extraction of side line pollutant and method for decomposing additional.Chinese Patent Application No. 201110340055.3
Disclose a kind of Industrial reverse osmosis film device pollutant On-line testing and method for decomposing, select commercial reverse osmosis membrane to make side line film
Assembly, the carrier extracted as key pollutants；Side line membrane module is parallel in Industrial reverse osmosis film device, regulates side line film
The Inlet and outlet water valve opening size of assembly, to control the crossflow velocity of water inlet；Time recording side line membrane module in running
Aquifer yield changes, when the relatively initial aquifer yield of aquifer yield declines 50～95%, then it is assumed that contaminated reverse osmosis membrane reaches to dissect to be wanted
Ask；Take out contaminated reverse osmosis membrane and carry out observation and the anatomy of pollutant；Bronsted lowry acids and bases bronsted lowry is used respectively contaminated reverse osmosis membrane to be entered
Row soaking and washing, the content size of specific pollutants in detection cleanout fluid.This method reduces some drawbacks of first method,
But yet suffer from deficiency: side line pollutant and original system start parallel work-flow from former water, but due to large-scale membrane component with
The HYDRODYNAMIC CONDITION RELATING TO of small-sized side line diaphragm element is not quite similar, and therefore pollutes asynchronous.The most large-scale membrane component has polluted ten
Divide serious, but parallel Miniature film disc element but pollutes lighter.
Relevant deficiency in above-mentioned reverse osmosis commercial Application causes the actual application of reverse osmosis to nevertheless suffer from the tired of pollutant
Disturbing, a lot of large scale systems are even forced to shorten the service life of film, cause operating cost significantly to rise.
Therefore, what those skilled in the art was devoted to develop a kind of reverse osmosis membrane apparatus pollution situation judges dress online
