Description
Technical field
The present invention relates to a kind of methods of water-treatment technology field, specifically utilize the technology of bi-membrane method production drinking water.
Background technology
Drinking Water in China pollution of waterhead problem getting worse, water source are subject to a large amount of industrialness organic pollutions and artificial synthesized
The pollution of organic matter, pipe network pollution etc. in addition, traditional tap water production technology can not meet requirement of the people to water quality.
Ultrafiltration is gradually recognized as third generation urban drinking water purification technique, right since ultrafiltration is mainly sieving actoion
There is good removal in turbidity, but suspended material, colloid and macromolecular substances can only be removed, and small organic molecule still can be saturating
It crosses.It is compared with common process, ultrafiltration producing water water quality has no clear superiority, and with the improvement of living standards, more and more rows
Industry and crowd propose the drinking water needs for higher quality.
In order to produce the drinking water of higher quality, it is a kind of that nanofiltration group technology is set to strengthen drinking water treatment after ultrafiltration
Good technical measures.Compared with ultrafiltration, nanofiltration possesses higher rejection, it is possible to remove the small molecule in ultrafiltration production water
Organic matter improves the security of drinking water.
The content of the invention
It is an object of the invention to overcome currently using ultrafiltration as core drinking water technology in cannot largely remove small point of part
The problem of sub- organic matter, the further small organic molecule strengthened in removal ultrafiltration production water increase nanofiltration group technology, form
Bi-membrane method produces the drinking water of high-quality, ensures water safety, is a technical solution innovated very much.The present invention be by with
What lower technical solution was realized, specifically comprise the following steps：
1. drinking water production device mainly by raw water box (2), booster pump (3), hyperfiltration membrane assembly (4), intermediate water tank (5),
Booster pump (6), nanofiltration membrane component (7) composition.Agitating device wherein in raw water box (2), intermediate water tank (5) is set, ensures water quality
Isotropic stable；
2. hyperfiltration membrane assembly (4), nanofiltration membrane component (7) are during water is produced using cross-flow filtration, each type of film
Component visual water quality situation is run using plural serial stage, is setting value using PLC Frequency Converter Controls each membrane module production water flow,
Concentrated water flow adjusts keep constant daily manually；
It 3. can be in raw water box (2), the interior dosing coagulant of intermediate water tank (5) or Powdered Activated Carbon and film depending on raw water quality situation
Component forms on-line filtration, to further improve effluent quality, while reduces fouling membrane.
Description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the process flow chart that bi-membrane method produces drinking water, wherein：1. raw water；2. raw water box；3. booster pump；4. surpass
Filter membrane component；5. intermediate water tank；6. booster pump；7. nanofiltration membrane component；8. inlet valve；9. concentrated water valve；10. produce penstock；
11. inlet valve；12. concentrated water valve；13. produce penstock.
Fig. 2 is raw water in embodiment 1, and water is produced in ultrafiltration, and the TOC and COD of water are produced in nanofiltrationMnFigure.
Fig. 3 is the three-dimensional fluorescence figure of raw water in embodiment 1.
Fig. 4 is three fluorograms that water is produced in ultrafiltration in embodiment 1.

Specific embodiment
It elaborates below to the embodiment of the present invention：The present embodiment is carried out lower based on the technical solution of the present invention
Implement, give detailed embodiment, but protection scope of the present invention is not limited to following embodiments.
Fig. 2~5 are the bi-membrane method production drinking water examples using certain micro-polluted surface lake water as raw water.Ultrafiltration, nanofiltration membrane component
Output water TOC and CODMnAs a result respectively as shown in Fig. 2, the TOC, COD of hyperfiltration membrane assembly production waterMnRemoval rate is only respectively 23%,
31%, it is limited to small organic molecule removal, still there is pollution machine object containing more in water；With respect to nanofiltration membrane component production water TOC,
CODMnRemoval rate is apparent, is up to respectively 89%, and 77%, it can be seen that good for the removal effect of organic matter.In addition use
Three fluorescence are respectively to raw water, and hyperfiltration membrane assembly production water, nanofiltration membrane component production water is detected, as shown in Fig. 3,4,5, in raw water
There are apparent two peaks, be respectively class tyrosine and class tryptophan substance, are produced from the two peaks in water in ultrafiltration apparent decrease, but
Apparent peak is not found in nanofiltration production water.It can be seen that nanofiltration can be with the removal of non-selectivity for organic matter.To sum up, nanofiltration is for water
Middle organic matter has good removal effect, and can be with the removal of non-selectivity, suitable for the production of high-quality drinking water.
Using above-mentioned desirable embodiment according to the invention as enlightenment, by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determine its technical scope according to right.
