Specific embodiment
A kind of specific structure for the antipollution water treatment facilities that the electrophoresis and membrane separating method of the utility model combine is such as
Shown in Fig. 1 ~ Fig. 5, including be sequentially arranged from the front to the back deceleration water inlet 1, prefilter room 2, electric treatment room 3, postposition filtering
Room 4 and water outlet 5.Releasable connection between each component guarantees the processing capacity of water treatment facilities so that each component can be changed periodically.
Deceleration water inlet 1 is in flaring form, its caliber is in increase tendency from the front to the back.So when sewage flows into water inlet of slowing down
When mouth 1, due to the increase of its caliber, flow velocity can slow down, to be conducive to the subsequent processing to sewage.
As shown in Fig. 2, prefilter room 2 successively includes PP cotton filter element 21, preposition activated charcoal 22 and pore yarn from the front to the back
Net 23, preposition activated charcoal 22 are sandwiched and fixed between PP cotton filter element 21 and pore gauze 23.
PP cotton filter element 21 be tubulose filter core, by non-toxic and tasteless polypropylene particles by heating melting, spinneret, traction,
Receive forming and be made, to stop the large particulate matters such as iron rust, silt, worm's ovum in water, and the big, pressure difference with filtering traffic
Small advantage.
Preposition activated charcoal 22 was used for educt in drainage, microorganism, part heavy metal ion, and water can be effectively reduced
Coloration.
So the setting of prefilter room 2 first is that water quality can be improved, second is that having shared Partial filtration task, has filtered off part
The inexpungible impurity in electric treatment room 3 is conducive to the service life for improving the utility model.
The structure of electric treatment room 3 is as shown in Figure 3 and Figure 4, and including the cabinet 31 that front and rear ends are open, cabinet is interior along upper
Support plate 32 is distributed in lower direction.The support chip 35 that support plate 32 is obliquely installed by muti-piece forms, and adjacent two pieces of support chips 35 are right
Setting is connect, thus in the perpendicular perpendicular to water (flow) direction, the support plate broken line type end to end in multiple Z-shapeds.
Water supply has been respectively formed between adjacent two support chip 35 and between 32 top of respective support piece 35 and cabinet, bottom box face
Flow the water stream channel flowed through from the front to the back.It is respectively provided on the front and back sides at the top of cabinet 31, bottom sides and support chip 35
There is electrode strip.Electrode strip includes positively charged positive electrode item 33 and electronegative negative electrode item 34, is located on same side (support
The bottom sides of the respective side of piece 35, the top-side of cabinet 31 or cabinet 31) the electrically charged pole of adjacent two strip electrodes item institute
Property on the contrary, along directly corresponding (i.e. in the up-down direction directly corresponding) the two electrically charged poles of electrode strip institute of Transverse to the flow direction
Property is opposite.In this embodiment, each electrode strip is by AC power supply, so the polarity of positive electrode item 33 and negative electrode item 34
The exchange of meeting generating period.
The vertical cross-section of support plate 32 broken line type end to end in multiple zigzags, can even more rise on supporting box 31
The effect of lower two sides is so that 3 structure of electric treatment room is more firm.
When water flow in electric treatment room 3 by being provided between each plate of electrode strip, under the electric field action of dense distribution, one
A little charged particles and ion can be attracted to counter electrode plate side due to electrophoresis.It simultaneously also can be right using the principle of electrolytic cell
Water part heavy metal ion is handled, and is restored to some heavy metal ion on electrode plate, thus make water flow obtain into
The processing of one step.So the shape of support plate 32 is arranged, opposite polarity electricity is set along support chip 35 and cabinet top/bottom part side
Pole item is conducive to increase 3 internal electric field density of electric treatment room, enhances electric treatment effect.
Certainly, in other embodiments, it is also possible that the electrode strip polarity on same side is identical, or in the same side
One electrode strip is only set on face.
The structure of postposition filter chamber 4 is as shown in figure 5, include post active carbon 41, nanofiltration membrane 42 and use positioned at its rear
In the pore gauze 43 that the two is fixed.Post active carbon 41 is used to adsorb the gas generated in electric treatment room 3 and electric treatment room 3
In the impurity that does not remove.Nanofiltration membrane 42 is used to retain the particle of 10 rans, further goes microorganism and bacterium etc. in water removal
Substance.It is enhancing nanofiltration membrane 42 to the service life of the equimolecular adsorption effect of protein, raising nanofiltration membrane 42, nanofiltration membrane 42 is remote
Side loads from electric treatment room 3 have halloysite nanotubes.The surface of halloysite nanotubes is hydrophilic radical, can be to protein
Equal molecules play effective anti-absorption, anti-fouling effect.It and is to make nanofiltration membrane 42 that there is anti-microbial property, load in halloysite nanotubes
There is silver ion.Above structure makes the nanofiltration membrane 42 of the utility model be even more to be provided with easy to clean, resistant to pollution advantage.
Process is as follows when the utility model handles sewage: when sewage flows into deceleration water inlet 1, due to the increase of its caliber,
Flow velocity is caused to slow down, to be conducive to the subsequent multi step strategy to sewage.Sewage flows into prefilter room 2, first passes through the filter of PP cotton
Core 21 removes silt, the large particulate matters such as suspended matter, then by preposition activated charcoal 22, removes the educt of smaller particle, micro- life
Peculiar smell in object, part heavy metal ion and water.Just treated, and water body flows into electric treatment room 3, when by between electrode plate,
Under the electric field action of dense distribution, some charged particles and ion are since electrophoresis is adsorbed on counter electrode plate side, simultaneously
Water part heavy metal ion can also be handled using the principle of electrolytic cell, some heavy metal ion is made to be restored to electrode
On plate, so that water be made to be further processed.Behind water body outflow electric treatment room 3 after reprocessing, again by post active carbon
41 adsorbed water bodies pass through the gas generated when electric treatment room, while further the band not being removed when electric treatment room 3 is passed through in barrier
Electric particle and heavy metal ion.Halloysite nanotubes nanofiltration membrane 42 finally through overload silver, using the centrifugation of nanofiltration membrane,
To be trapped in the particle of 10 rans, while sterilizing is carried out to water body using the silver ion loaded in nanotube, removed
The substances such as bacterium, microorganism avoid its deposition from being adsorbed on the surface of nanofiltration membrane, to increase the use longevity of the utility model
Life.
