Description
Technical field
The present invention relates to water-treatment technology field, more particularly to a kind of circulating water treatment method.
Background technology
Currently known water technology has two major classes.The first kind is medicament water process, is added into recirculated water a certain amount of
Chemical agent, prevent water in easy scale-forming ion be combined so as to reach improve recirculated water cycles of concentration purpose, make circulation
Water utilization rate can improve, and shortcoming is that recirculated water cannot be concentrated infinitely, must have one after the cycles of concentration that water reaches certain
Quantitative blowdown, so that recirculated water cycles of concentration balances；Second class is equipment water process, uses counter-infiltration, demineralizer or mixed bed
Zwitterion in removing water is carried out Deng water treatment facilities, so as to reach the purpose of the removing circulation water hardness, but these equipment have
One common disadvantage is that blowdown flow rate is big.
The content of the invention
Therefore, the present invention proposes one kind can use recirculated water with high usage, and at the recirculated water of without sewage discharge
Reason method.
The invention provides a kind of circulating water treatment method, including：Filtration treatment is carried out to industrial raw water, obtains to remove and hangs
The clear water of floating impurity；The clear water for removing suspended impurity is subjected to reverse-osmosis treated, primary production water and condensed water are obtained, wherein one
Secondary product water, which enters in circulating water pool, to be recycled；The condensed water that counter-infiltration is obtained carries out electrodialysis process, obtains two
Secondary product water and high power condensed water, wherein afterproduct water, which enter in circulating water pool, to be recycled or returns in industrial raw water,
The high power condensed water enters in water storage box.
Further, described that industrial raw water is carried out in filtration step using filter, the filter of selection is multimedium
Filter.
Further, the filtrate used in the more medium filter includes quartz sand, anthracite and manganese sand.
Further, described to carry out the clear water for removing suspended impurity in reverse-osmosis treated step, selection is hollow fibre
The membrane separation plant of dimension formula or rolling.
Further, the membrane separation plant uses anisotropic membrane or composite membrane.
Further, the condensed water that counter-infiltration is obtained is carried out in electrodialysis process step, from pole-reversing electroosmosis
EDR equipment.
Further, a kind of described circulating water treatment method also includes the high power condensed water in the water storage box being used in
Water closet, in washup pond or sprinkling truck.
The equipment amount that the present invention uses is few and small volume, removable chlorion are simple to operate without dosing.And waste water
The rate of recovery it is high, caused a small amount of sewage can be used for flushing the toilet, ore cleaning, dedusting of irrigating the fields, efficiently utilize water resource.
The additional aspect and advantage of the present invention will be set forth in part in the description, and will partly become from the following description
Obtain substantially, or recognized by the practice of the present invention.
Brief description of the drawings
Fig. 1 is a kind of flow chart of circulating water treatment method of the embodiment of the present invention；
Fig. 2 is a kind of FB(flow block) of circulating water treatment method of the embodiment of the present invention.
Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
The embodiments of the invention provide a kind of circulating water treatment method, as shown in figure 1, including：
Step S1, filtration treatment is carried out to industrial raw water, obtains the clear water for removing suspended impurity.The filter of this step can
From more medium filter, the more medium filter is to utilize one or more of filter mediums, under pressure turbid
The higher water of degree is conventional so as to which effectively removing suspended impurity makes clarification of water by certain thickness granular or non-grain material
Filtrate has quartz sand, anthracite, manganese sand etc., is mainly used in water process turbidity removal, softened water, prime pretreatment of pure water etc., water outlet
Turbidity is up to less than 3 degree.
Step S2, the clear water for removing suspended impurity is subjected to reverse-osmosis treated, obtains primary production water and condensed water, wherein
Primary production water, which enters in circulating water pool, to be recycled.What is selected in this step is hollow fiber form or the UF membrane of rolling
Equipment, wherein permeable membrane are anisotropic membrane or composite membrane.Counter-infiltration is also known as reverse osmosis, be one kind using pressure differential as motive force, from
The UF membrane operation of solvent is isolated in solution.Pressure is applied to the feed liquid of film side, it is molten when pressure exceedes its osmotic pressure
Agent can make inverse osmosis against the direction of naturally osmotic, so as in the solvent that is passed through of low-pressure side of film, i.e., in this step
Primary production water；The solution that high-pressure side is concentrated, i.e. condensed water.
Step S3, the condensed water that counter-infiltration is obtained carry out electrodialysis process, obtain afterproduct water and high power condensed water,
Wherein afterproduct water enters in circulating water pool and recycles or return in industrial raw water, and the high power condensed water enters water storage
In case.Preferably, the condensed water that counter-infiltration is obtained is carried out in electrodialysis process step, from the EDR of pole-reversing electroosmosis
Equipment.EDR technologies are a kind of electrochemical desalination processes, and electrodialytic technique and ion exchange technique are organically combined together by it,
Instead of traditional ion exchange resin technique, can effectively remove micro electrolytic ion impurity in water removal, have can continuously, nothing
Acid-alkali regeneration is needed to have the function that concentrating and separating sewage.EDR equipment is mainly handed over by medium between anodic-cathodic plate, ion exchange resin, ion
Change the composition such as film.When the ion in water is ion exchanged resin capture, water obtains desalting and purifying；In the presence of electric field, it is caught
Cation permeable anode membrane, the anion-permeable cavity block obtained, after the ion permeable amberplex in the water including chlorion
Collect discharge into concentrated water room.Under certain electric current, hydrone is ionized to H ﹢, OH ﹣ ions, and exhausted resin is regenerated,
So as to realize continuous production water, cyclic regeneration.
In a specific embodiment of the invention, as shown in Fig. 2 the counter-infiltration rate of recovery of the clear water after 100 tons of filterings is
75%, the EDR rate of recovery are 90%, i.e. EDR only discharges 2.5 tons of waste water, can produce 75 tons of primary production water and 22.5 tons of secondary productions
Product water.And discharge waste water be collected into water storage box, lavatory is washed in water closet, in washup pond washup stone or
Person is used in place dedusting in sprinkling truck, the part water is fully used, has saved water resource.
The equipment amount that the present invention uses is few and small volume, removable chlorion are simple to operate without dosing.And waste water
The rate of recovery it is high, caused a small amount of sewage can be used for flushing the toilet, ore cleaning, dedusting of irrigating the fields, efficiently utilize water resource.
Although embodiments of the invention have been shown and described above, it is to be understood that above-described embodiment is example
Property, it is impossible to limitation of the present invention is interpreted as, one of ordinary skill in the art within the scope of the invention can be to above-mentioned
Embodiment is changed, changed, replacing and modification.
