Description
Technical field
The utility model relates to high slat-containing wastewater electrodialysis process apparatus fields, especially at a kind of high slat-containing wastewater desalination
Manage device.
Background technique
China's strong brine processing technique is started late, and related industry development relatively lags behind.Currently, reverse osmosis membrane technology is big
Sizable application is in the processing of high concentration saline sewage, mostly in field of seawater desalination.In recent years, with China's economic development and industry into
The contradiction of the quickening of journey, shortage of water resources and enterprise water use aggravation becomes increasingly conspicuous, more and more advanced treatment of wastewater and reuse
Technology is used by enterprise.Untreated high-COD waste water with high salt is discharged into natural water, not only can polluted-water, cause environment
Pollution, and will also result in certain threat to the health of aqueous bio and the mankind.At present for high-COD waste water desalination with high salt
Method mainly includes heating power desalination method, chemical decladding method, Electro Sorb desalination process and embrane method etc., in other works relatively lower compared with embrane method
That there are energy consumptions is high for skill, the tediously long complicated, disadvantages such as processing cost is big, salt rejection rate is low for the treatment of process.Therefore, embrane method handles height with high salt
COD waste water becomes its important research direction, especially film concentration technique and has obtained faster development, is alleviating enterprise's use at present
Water pressure reduces sewage discharge and protection environment etc. acquirement significant results.However, with external sewage " zero-emission " or
The advanced level of " become zero-emission " is compared to there is also larger gaps.Sewage treatment end still have 15%~30% strong brine by
Outlet is diluted in the shortage feasible recoverying and utilizing method of Technological Economy, does not realize the reduction of pollutants emission intensity really,
The waste of water resource and salts resources is caused simultaneously.
The performance of embrane method industry water desalter mainly includes salt rejection rate, water yield, rate of recovery etc., while also needing to consider
The service life of film.When using embrane method desalinating process, with the increase of use time, film itself is because of Ca, Mg etc. for having in water
The precipitating fouling of high rigidity ion changes the chemical property and physical structure of film, makes the exchange capacity and selective penetrated property of film
Decline, mechanical strength reduce, on the one hand easy embrittlement etc. reduces the salt rejection rate, water yield and the rate of recovery of film separation system, thus
The ability of water treatment system is reduced, the service life of film is on the other hand also shortened.Such as electroosmose process, due to ion
The transport number in transport number and solution in film has larger difference, causes concentration polarization, when film two sides concentration difference is excessive, again
The polarization that can cause and aggravate film can precipitate fouling after polarization, block water stream channel, increase resistance to water-flow, to reduce film dress
The performance (salt rejection rate, water yield and the rate of recovery) set, and influence the normal peace of treated water quality and quantity and electrodialysis plant
Row for the national games, and then shorten the service life of film.
For example, Chinese patent (CN205821089U) discloses a kind of processing system of photosensitive material production waste water, it is described
Processing system is used to handle photosensitive material production waste water, and the processing system of the production waste water includes: wastewater collection pond,
For being stored to production waste water；Pretreatment system, for being pre-processed to photosensitive material production waste water；Electric drive membrane system
System, for carrying out desalting processing to pretreated production waste water；And after-treatment system, for the processing of electric drive membranous system
Production waste water afterwards is post-processed.At the minimizing and concentration that processing system provided by the utility model passes through nanofiltration system
Reason, so that salinity and content of organics improve in waste water, wastewater flow rate reduces, and significantly reduces the investment of electric drive membranous system
Cost；It is effectively reduced the salinity of desalination solution in diluting compartment by electric drive membranous system, realizes the separation of organic matter and salinity.
But the rate of recovery of the production water of its electric drive membranous system only has 66.7%, fails to achieve the effect that efficiently to divide salt, while increasing it
Discharge water causes the risk of secondary pollution to surrounding enviroment, and unresolved amberplex is because using the longevity caused by concentration polarization
Order shorter problem.
