Description
本發明係涉及能夠將鈉離子等陽離子或氯化物離子等陰離子加以過濾的過濾機構。The present invention relates to a filtration mechanism capable of filtering an anion such as a sodium ion or an anion such as a chloride ion.
過去有一種過濾膜是逆滲透膜(RO膜)，具有水能通過而鹽類等水以外的不純物不能穿過的性質(非專利文獻1)。In the past, there is a reverse osmosis membrane (RO membrane) which has a property that water can pass through and impurities other than water such as salts cannot pass through (Non-Patent Document 1).
這種膜利用逆滲透現象，即如果對濃度較高的一側從外部施加超過滲透壓之差的壓力，就只有水分子會從濃度較高的一側流向較低的一側。This membrane utilizes a reverse osmosis phenomenon, that is, if a higher concentration side is externally applied with a pressure exceeding the difference of the osmotic pressure, only water molecules flow from the higher concentration side to the lower side.
例如，當要以40%的水回收率(意味著要將剩餘的60%作為濃縮水捨棄)而從平均鹽分3.5%的海水獲得符合日本飲用水基準的鹽分0.01%的淡水時，以2005年的最低水準就需要55氣壓左右。For example, when a 40% water recovery rate is used (meaning that the remaining 60% is to be discarded as concentrated water) and fresh water is obtained from the average salt content of 3.5% of seawater to 0.01% of the salt according to the Japanese drinking water standard, The minimum level requires about 55 air pressure.
然而，這就需要施加相當高的高壓。However, this requires a relatively high pressure to be applied.

為此，本發明的目的在於提供一種不施加高壓也能進 行過濾的過濾機構。Accordingly, it is an object of the present invention to provide a way to enter without applying high pressure. Filtering mechanism for filtering.
為了實現上述目的，本發明係採用以下技術手段。In order to achieve the above object, the present invention employs the following technical means.
(1)本發明的過濾機構係利用離子滲透性的陽極電極來電氣性地阻止陽離子滲透，且同時有選擇地使陰離子滲透，並利用離子滲透性的陰極電極來電氣性地阻止陰離子滲透，且同時有選擇地使陽離子滲透。(1) The filter mechanism of the present invention utilizes an ion-permeable anode electrode to electrically block cation penetration while selectively infiltrating anions and electrically blocking anion permeation using an ion-permeable cathode electrode, and At the same time, the cation is selectively infiltrated.
成為處理對象的被處理水例如有海水、含食鹽水、含鹽分水等，並且能夠將這些水作為飲用水或純水來加以再利用。另外，例如還有洗滌器廢水、冷卻塔．冷卻機的冷卻循環水、鍋爐水，並且能夠將這些硬水加以軟化。經過過濾而減少乃至被除去的離子例如有矽石、Ca、Mg、Fe、Mn、Cd、Pb、重金屬類、硫酸離子、硝酸離子等。The water to be treated to be treated includes, for example, sea water, brine, salty water, and the like, and these waters can be reused as drinking water or pure water. In addition, there are, for example, scrubber wastewater, cooling towers. The cooler cools the circulating water, the boiler water, and can soften these hard waters. The ions which are reduced or even removed by filtration are, for example, vermiculite, Ca, Mg, Fe, Mn, Cd, Pb, heavy metals, sulfate ions, nitrate ions, and the like.
採用這種過濾機構，由於是利用離子滲透性的陽極電極來電氣性地阻止陽離子滲透，且同時有選擇地使陰離子滲透，因此即使不對如逆滲透膜般的小孔徑施加高壓，也能利用電氣性斥力來阻止陽離子滲透。With such a filter mechanism, since the ion permeation anode electrode is used to electrically block cation penetration and at the same time selectively infiltrate the anion, the electric can be utilized even if a high pressure is not applied to a small pore diameter such as a reverse osmosis membrane. Sex repulsive force to prevent cation penetration.
另外，由於是利用離子滲透性的陰極電極來電氣性地阻止陰離子滲透，且同時有選擇地使陽離子滲透，因此即使不對如逆滲透膜般的小孔徑施加高壓，也能利用電氣性斥力來阻止陰離子滲透。In addition, since the ion-permeable cathode electrode is used to electrically block anion permeation and selectively infiltrate the cation, the electric repulsion can be prevented by applying a high pressure to a small pore diameter such as a reverse osmosis membrane. Anion penetration.
此處，只要使不會導致電解的電流流過，從而要利用電氣性斥力來進行離子分離即可。Here, as long as a current that does not cause electrolysis flows, it is only necessary to perform ion separation using an electrical repulsive force.
(2)也可以利用離子滲透性的陽極電極來電氣地阻止陽 離子滲透，且同時有選擇地使水和陰離子滲透，並利用離子滲透性的陰極電極來電氣地阻止陰離子滲透，且同時有選擇地使水和陽離子滲透。(2) It is also possible to electrically block the anode by using an ion-permeable anode electrode. Ion permeation, and at the same time selectively infiltrate water and anions, and utilize ion-permeable cathode electrodes to electrically block anion permeation while selectively infiltrating water and cations.
採用這種過濾機構，由於是利用離子滲透性的陽極電極來電氣性地阻止陽離子滲透，且同時有選擇地使水和陰離子滲透，因此即使不對如逆滲透膜般的小孔徑施加高壓，也能利用電氣性斥力來阻止陽離子滲透。With such a filter mechanism, since the ion-permeable anode electrode is used to electrically block cation penetration and at the same time selectively infiltrate water and anions, even if a high pressure is not applied to a small pore diameter such as a reverse osmosis membrane, Electrical repulsion is used to prevent cation penetration.
另外，由於是利用離子滲透性的陰極電極來電氣性地阻止陰離子滲透，且同時有選擇地使水和陽離子滲透，因此即使不對如逆滲透膜般的小孔徑施加高壓，也能利用電氣性斥力來阻止陰離子滲透。In addition, since the ion permeating cathode electrode is used to electrically block anion permeation and at the same time selectively infiltrate water and cations, electrical repulsion can be utilized even if high pressure is not applied to a small pore diameter such as a reverse osmosis membrane. To prevent anion penetration.
這種過濾機構和電滲析之間的區別在於，電滲析時要在正負的電極相互間配設陽離子膜和陰離子膜，使被處理水流過它們之間，而在電極間流動的直流電流會成為驅動力，使陽離子滲透陽離子膜，陰離子滲透陰離子膜，從而減少乃至被除去，且陽離子和陰離子會從被處理水減少乃至除去或被濃縮，而本過濾機構則是通過被處理水自身滲透離子滲透性電極而從被處理水減少乃至除去陽離子或陰離子。The difference between the filter mechanism and the electrodialysis is that a cationic membrane and an anion membrane are disposed between the positive and negative electrodes during electrodialysis, so that the water to be treated flows between them, and the direct current flowing between the electrodes becomes The driving force causes the cation to permeate the cation membrane, the anion penetrates the anion membrane, thereby reducing or even being removed, and the cation and anion are reduced or even removed or concentrated from the treated water, and the filtering mechanism penetrates the ion permeation through the treated water itself. The electrode is reduced from the water to be treated or even removed from the cation or anion.
採用本過濾機構，能夠具有即使壓力低也能運轉、且處理面積大(每一單位容積的開孔面積大)的優點，且能夠代替UF膜+RO膜。According to the present filtration mechanism, it is possible to operate even when the pressure is low, and the processing area is large (the opening area per unit volume is large), and the UF film + RO film can be replaced.
(3)也可以具備非離子滲透性電極，且將前述離子滲透性電極與非離子滲透性電極互為相對地配置而使電流流過 它們之間，並將滲透了離子滲透性電極的水匯集起來。(3) A non-ion permeable electrode may be provided, and the ion-permeable electrode and the non-ion-permeable electrode may be disposed to face each other to cause a current to flow therethrough Between them, water that has penetrated the ion permeable electrode is collected.
例如，如果具備非離子滲透性的陰極電極，且將前述離子滲透性的陽極電極與非離子滲透性的陰極電極互為相對地配置而使電流流過它們之間，就能將滲透了離子滲透性的陽極電極從而減少乃至除去了陽離子的水匯集起來。For example, if a non-ion permeable cathode electrode is provided and the ion-permeable anode electrode and the non-ion permeable cathode electrode are disposed opposite each other to allow a current to flow therebetween, the ion permeation can be infiltrated. The scented anode electrode thus reduces or even removes the cation water.
另一方面，如果具備非離子滲透性的陽極電極，且將前述離子滲透性的陰極電極與非離子滲透性的陽極電極互為相對地配置而使電流流過它們之間，就能將滲透了離子滲透性的陰極電極從而減少乃至除去了陰離子的水匯集起來。On the other hand, if a non-ion permeable anode electrode is provided and the ion-permeable cathode electrode and the non-ion permeable anode electrode are disposed opposite each other and a current flows between them, the permeation can be performed. The ion-permeable cathode electrode thereby reduces or even removes the anion-containing water.
(4)也可以將離子滲透性的陽極電極與離子滲透性的陰極電極層疊，且將滲透了這些電極的水匯集起來。(4) It is also possible to laminate an ion-permeable anode electrode and an ion-permeable cathode electrode, and to collect water infiltrated with these electrodes.
採用上述結構，能夠將水及陽離子和陰離子依次過濾來減少乃至除去。而陽離子和陰離子哪個先過濾都可以。With the above structure, water, cations and anions can be sequentially filtered to reduce or even remove. Which of the cations and anions can be filtered first.
(5)也可以在陽極電極與陰極電極之間發生電解，將被處理水中的被氧化物質加以分解。(5) Electrolysis may occur between the anode electrode and the cathode electrode to decompose the oxidized substance in the water to be treated.
採用上述結構，能夠同時進行被處理水的脫鹽和淡水化、以及被處理水中的污物(被氧化物質)的分解和淨化。According to the above configuration, it is possible to simultaneously perform dehydration and desalination of the water to be treated, and decomposition and purification of the contaminant (oxidized substance) in the water to be treated.
成為處理對象的被處理水例如有化學工廠或液晶製造工廠、半導體製造工廠等的工廠廢水、廢液、以及生活廢水等，並且能夠將這些廢水加以淨化。The water to be treated to be treated includes, for example, factory wastewater, waste liquid, and domestic wastewater in a chemical factory, a liquid crystal manufacturing plant, a semiconductor manufacturing plant, and the like, and these wastewaters can be purified.
本發明採用上述結構，且具有以下效果。The present invention adopts the above structure and has the following effects.
由於能夠利用電氣性斥力來阻止陽離子或陰離子滲 透，因此即使不施加高壓，過濾機構也能進行過濾。Due to the ability to use electrical repulsion to prevent cation or anion seepage It is transparent, so the filter mechanism can filter even if no high pressure is applied.
圖1係說明本發明過濾機構的實施形態1的系統流程圖。BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a system flow chart for explaining a first embodiment of a filter mechanism of the present invention.
圖2係說明本發明過濾機構的實施形態2的系統流程圖。Fig. 2 is a system flow chart for explaining the second embodiment of the filter mechanism of the present invention.
圖3係說明本發明過濾機構的實施形態2的系統流程圖。Fig. 3 is a system flow chart for explaining the second embodiment of the filter mechanism of the present invention.
以下說明本發明的實施形態。Hereinafter, embodiments of the present invention will be described.
如圖1所示，本實施形態的過濾機構係利用離子滲透性的陽極電極1來電氣性地阻止陽離子滲透，且同時有選擇地使陰離子滲透，並利用離子滲透性的陰極電極2來電氣性地阻止陰離子滲透，且同時有選擇地使陽離子滲透。As shown in Fig. 1, the filter mechanism of the present embodiment electrically blocks cation penetration by the ion-permeable anode electrode 1, and selectively infiltrates the anion, and electrically conducts the ion-permeable cathode electrode 2. The anion permeation is prevented, and at the same time, the cation is selectively infiltrated.
前述離子滲透性電極(陽極、陰極)是使用多孔質(滲透性)的導電性陶瓷。該多孔質的孔徑例如可以形成為1nm、10Å，並且能夠恰當地設定開孔率。The ion-permeable electrode (anode, cathode) is a porous (permeability) conductive ceramic. The porous pore diameter can be formed, for example, at 1 nm or 10 Å, and the opening ratio can be appropriately set.
前述陶瓷的材料可以是鋯氧(=二氧化鋯，ZrO2 )、釔(=氧化釔，Y2 O3 )等。其中，如果使用鋯氧(融點2715℃，沸點4300℃)，則彈性和韌性佳。如果其中混有釔，則韌性和耐碎裂性更佳。通過混入氧化鋁(=aluminium oxide，Al2 O3 )，能夠降低燒制溫度。不過，如果混入了過多的氧化 鋁，則容易碎裂。The material of the ceramic may be zirconium oxide (=zirconia, ZrO 2 ), yttrium (=yttrium oxide, Y 2 O 3 ) or the like. Among them, if zirconium oxide (melting point of 2715 ° C, boiling point of 4300 ° C) is used, elasticity and toughness are good. If it is mixed with bismuth, the toughness and chipping resistance are better. By mixing alumina (=aluminium oxide, Al 2 O 3 ), the firing temperature can be lowered. However, if too much alumina is mixed in, it is easily broken.
為了使所述陶瓷具有導電性，可以混合鎳的微粒子。一旦混合了鎳的微粒子，就能夠降低陶瓷燒制時的溫度。In order to make the ceramic electrically conductive, fine particles of nickel may be mixed. Once the nickel fine particles are mixed, the temperature at which the ceramic is fired can be lowered.
從圖中右側起依次配設非離子滲透性的陽極電極3、離子滲透性的陰極電極2、離子滲透性的陽極電極1、以及非離子滲透性的陰極電極4，從下方供給食鹽水，再使不會導致電解的程度的電流流過，並利用電氣性斥力來進行離子分離。A non-ion permeable anode electrode 3, an ion permeable cathode electrode 2, an ion permeable anode electrode 1, and a non-ion permeable cathode electrode 4 are disposed in this order from the right side in the drawing, and brine is supplied from below, and then A current that does not cause electrolysis flows, and ion detachment is performed using an electrical repulsion.
這樣一來，減少乃至除去鈉離子後的水就會從非離子滲透性的陽極電極3與離子滲透性的陰極電極2之間排出，接近純水的水會從離子滲透性的陰極電極2與離子滲透性的陽極電極1之間排出，而減少乃至除去氯化物離子後的水就會從離子滲透性的陽極電極1與非離子滲透性的陰極電極4之間排出。In this way, the water after reducing or even removing the sodium ions is discharged between the non-ion permeable anode electrode 3 and the ion-permeable cathode electrode 2, and the water close to the pure water will pass from the ion-permeable cathode electrode 2 and The ion-permeable anode electrode 1 is discharged between the ion-permeable anode electrode 1 and the non-ion-permeable cathode electrode 4, and the water which is reduced or even after the removal of the chloride ions is discharged.
成為處理對象的被處理水除了含食鹽水外還有海水等，並且能夠將這些水作為飲用水或純水來加以再利用。另外，成為處理對象的被處理水例如還有洗滌器排水、冷卻塔．冷卻機的冷卻循環水、鍋爐水等，並且能夠將這些硬水加以軟化。The water to be treated to be treated may be seawater or the like in addition to the saline solution, and these waters can be reused as drinking water or pure water. In addition, the treated water to be treated is, for example, a scrubber drain and a cooling tower. The cooling machine cools the circulating water, boiler water, etc., and can soften these hard waters.
經過過濾而被減少乃至除去的離子除了鈉或氯化物之外，例如有矽石、Ca、Mg、Fe、Mn、Cd、Pb、重金屬類、硫酸離子、硝酸離子等。In addition to sodium or chloride, the ions which are reduced or even removed by filtration include, for example, vermiculite, Ca, Mg, Fe, Mn, Cd, Pb, heavy metals, sulfate ions, nitrate ions, and the like.
以下將說明本實施形態的過濾機構的使用狀態。The state of use of the filter mechanism of the present embodiment will be described below.
採用這種過濾機構，由於是利用離子滲透性的陽極電 極1來電氣性地阻止陽離子滲透，且同時有選擇地使陰離子滲透，因此即使不對如逆滲透膜般的小孔徑施加高壓，也能利用電氣性斥力來阻止陽離子滲透。Using this filter mechanism, because it is an anodic electricity using ion permeability The pole 1 electrically blocks cation penetration and at the same time selectively infiltrates the anion, so that electrical repulsion can be utilized to prevent cation penetration even if high pressure is not applied to a small pore size such as a reverse osmosis membrane.
另外，由於是利用離子滲透性的陰極電極2來電氣性地阻止陰離子滲透，且同時有選擇地使陽離子滲透。因此即使不對如逆滲透膜般的小孔徑施加高壓，也能利用電氣性斥力來阻止陰離子滲透。Further, since the ion-permeable cathode electrode 2 is used to electrically block anion permeation, and at the same time, the cation is selectively infiltrated. Therefore, even if a high pressure is not applied to a small pore diameter such as a reverse osmosis membrane, an electrical repulsion can be utilized to prevent anion permeation.
由於能夠利用電氣性斥力來阻止陽離子或陰離子滲透，因此即使不施加高壓，過濾機構也能進行過濾。另外，採用本過濾機構，能夠具有即使壓力低也能運轉、且處理面積大(每一單位容積的開孔面積大)的優點，且能夠代替UF膜+RO膜。Since the repellency of the cation or anion can be prevented by the electrical repulsion, the filtration mechanism can perform filtration even if no high pressure is applied. Further, according to the present filtration mechanism, it is possible to operate even when the pressure is low, and the processing area is large (the opening area per unit volume is large), and the UF film + RO film can be replaced.
如圖2所示，本實施形態的過濾機構利用離子滲透性的陽極電極1來電氣性地阻止陽離子滲透，且同時有選擇地使水和陰離子滲透，並利用離子滲透性的陰極電極2來電氣性地阻止陰離子滲透，且同時有選擇地使水和陽離子滲透。As shown in Fig. 2, the filter mechanism of the present embodiment electrically blocks cation penetration by the ion-permeable anode electrode 1, and selectively infiltrates water and anions, and electrically uses the ion-permeable cathode electrode 2. The anion permeation is blocked sexually, and at the same time, water and cations are selectively infiltrated.
另外，在本實施形態中，具有非離子滲透性電極3、4，將所述離子滲透性電極1、2與非離子滲透性電極3、4互為相對地配置而使電流流過它們之間，且將滲透了離子滲透性電極1、2的水匯集起來。Further, in the present embodiment, the non-ion permeable electrodes 3 and 4 are provided, and the ion-permeable electrodes 1 and 2 and the non-ion-permeable electrodes 3 and 4 are disposed to face each other to cause a current to flow therebetween. And water that has permeated the ion-permeable electrodes 1, 2 is collected.
具體是，被投入海水的陰離子膜槽5具備非離子滲透性的陰極電極4(陰極無孔陶瓷膜)，將所述離子滲透性的陽極電極1(陽極有孔陶瓷膜)和非離子滲透性的陰極電極4隔著 襯墊S而互為相對地配置層疊，使電流在它們之間流動，再將滲透了離子滲透性的陽極電極1而減少乃至除去了陽離子後的陰離子濃縮水匯集到中央的集水管P。Specifically, the anion membrane tank 5 to which seawater is introduced is provided with a non-ion permeable cathode electrode 4 (cathode non-porous ceramic membrane), and the ion-permeable anode electrode 1 (anode-porous ceramic membrane) and non-ion permeability Cathode electrode 4 The spacers S are disposed so as to face each other, and current is caused to flow therebetween, and the anion-concentrated water obtained by absorbing the ion-permeable anode electrode 1 and having the cation removed is collected in the central water collection tube P.
然後，被供給所述陰離子濃縮水的陽離子膜槽6具備非離子滲透性的陽極電極3(陽極無孔陶瓷膜)，將所述離子滲透性的陰極電極2(陰極有孔陶瓷膜)和非離子滲透性的陽極電極3隔著襯墊S而互為相對地配置層疊，使電流在它們之間流動，再將滲透了離子滲透性的陰極電極2而減少乃至除去了陰離子後的純水匯集到中央的集水管P。Then, the cation membrane tank 6 to which the anion-concentrated water is supplied is provided with a non-ion permeable anode electrode 3 (anode non-porous ceramic membrane), and the ion-permeable cathode electrode 2 (cathode-porous ceramic membrane) and non- The ion-permeable anode electrode 3 is disposed so as to face each other with the spacer S interposed therebetween, and a current flows between them, and the pure electrode water after the ion-permeable cathode electrode 2 is infiltrated and the anion is removed is collected. To the central collection pipe P.
另一方面，未通過所述離子滲透性的陽極電極1(陽極有孔陶瓷膜)的陽離子濃縮水會被送往濃縮水系統，而未通過所述離子滲透性的陰極電極2的陰離子濃縮水會被送往濃縮水系統，合流後作為濃縮水排放。On the other hand, the cation-concentrated water which has not passed through the ion-permeable anode electrode 1 (anode-porous ceramic membrane) is sent to the concentrated water system, and the anion-enriched water which has not passed through the ion-permeable cathode electrode 2 Will be sent to the concentrated water system, combined and discharged as concentrated water.
此外，本實施形態不是沿著互為相對的正負陶瓷電極使流體沿著電極間的通路流動，而是使液體沿著陶瓷電極直行而與滲透電極板的膜的方向垂直地流動。Further, in the present embodiment, the fluid does not flow along the path between the electrodes along the mutually opposing positive and negative ceramic electrodes, but the liquid flows straight along the ceramic electrode and flows perpendicularly to the direction of the film of the permeation electrode plate.
以下將說明本實施形態的過濾機構的使用狀態。The state of use of the filter mechanism of the present embodiment will be described below.
採用這種過濾機構，由於是利用離子滲透性的陽極電極1來電氣性地阻止陽離子滲透，且同時有選擇地使水和陰離子滲透，因此即使不對如逆滲透膜般的小孔徑施加高壓，也能利用電氣性斥力來阻止陽離子滲透。With such a filter mechanism, since the ion-permeable anode electrode 1 is used to electrically block cation penetration and at the same time selectively infiltrate water and anions, even if a high pressure is not applied to a small pore diameter such as a reverse osmosis membrane, Electrical repulsion can be utilized to prevent cation penetration.
另外，由於是利用離子滲透性的陰極電極2來電氣性地阻止陰離子滲透，且同時有選擇地使水和陽離子滲透，因此即使不對如逆滲透膜般的小孔徑施加高壓，也能利用電 氣性斥力來阻止陰離子滲透。In addition, since the ion-permeable cathode electrode 2 is used to electrically block anion permeation and selectively infiltrate water and cations, electricity can be utilized even if a high pressure is not applied to a small pore diameter such as a reverse osmosis membrane. A gas repulsion to prevent anion penetration.
由於能夠利用電氣性斥力來阻止陽離子或陰離子滲透，因此即使不施加高壓，過濾機構也能進行過濾。另外，採用本過濾機構，能夠具有即使壓力低也能運轉、且處理面積大(每一單位容積的開孔面積大)的優點，且能夠代替UF膜+RO膜。Since the repellency of the cation or anion can be prevented by the electrical repulsion, the filtration mechanism can perform filtration even if no high pressure is applied. Further, according to the present filtration mechanism, it is possible to operate even when the pressure is low, and the processing area is large (the opening area per unit volume is large), and the UF film + RO film can be replaced.
這種過濾機構和電滲析之間的區別在於，電滲析時要在正負的電極相互間配設陽離子膜和陰離子膜，使被處理水流過它們之間，而在電極間流動的直流電流會成為驅動力，使陽離子滲透陽離子膜，陰離子滲透陰離子膜，從而被減少乃至除去，且陽離子和陰離子會從被處理水減少乃至除去或被濃縮，而本過濾機構則是通過被處理水自身滲透離子滲透性的電極而從被處理水減少乃至除去陽離子、陰離子。The difference between the filter mechanism and the electrodialysis is that a cationic membrane and an anion membrane are disposed between the positive and negative electrodes during electrodialysis, so that the water to be treated flows between them, and the direct current flowing between the electrodes becomes The driving force causes the cation to permeate the cation membrane, the anion penetrates the anion membrane, thereby being reduced or even removed, and the cation and anion are reduced or even removed or concentrated from the treated water, and the filtering mechanism penetrates the ion permeation through the treated water itself. The electrode is reduced from the water to be treated and even removes cations and anions.
以下主要是以與上述實施形態1、2的區別來說明實施形態3。The third embodiment will be described below mainly in comparison with the first and second embodiments.
成為處理對象的被處理水例如有化學工廠或液晶製造工廠、半導體製造工廠等的工廠廢水、廢液、以及生活廢水等，並且能夠將這些廢水加以脫鹽．淨化。The water to be treated to be treated includes, for example, factory wastewater, waste liquid, and domestic wastewater in a chemical factory, a liquid crystal manufacturing plant, a semiconductor manufacturing plant, and the like, and can be desalted. Purification.
如圖3所示，被投入廢水的電解陰離子膜槽7具備非離子滲透性的陰極電極4(陰極無孔陶瓷膜)，將所述離子滲透性的陽極電極1(陽極有孔陶瓷膜)和非離子滲透性的陰極電極4隔著襯墊S而互為相對地配置層疊，使電流在它們之間 流動，再將滲透了離子滲透性的陽極電極1而減少乃至除去了陽離子後的陰離子濃縮水匯集到中央的集水管P。As shown in Fig. 3, the electrolytic anion membrane tank 7 to which the wastewater is introduced is provided with a non-ion permeable cathode electrode 4 (cathode non-porous ceramic membrane), and the ion-permeable anode electrode 1 (anode-porous ceramic membrane) and The non-ion permeable cathode electrode 4 is disposed to face each other across the spacer S so that the current is between them After flowing, the ion-permeable anode electrode 1 is infiltrated to reduce or even the anion-concentrated water from which the cation is removed is collected in the central water collection tube P.
然後，被供給所述陰離子濃縮水的電解陽離子膜槽8具備非離子滲透性的陽極電極3(陽極無孔陶瓷膜)，將所述離子滲透性的陰極電極2(陰極有孔陶瓷膜)和非離子滲透性的陽極電極3隔著襯墊S而互為相對地配置層疊，使電流在它們之間流動，再將滲透了離子滲透性的陰極電極2而減少乃至除去了陰離子後的純水匯集到中央的集水管P。Then, the electrolytic cation membrane tank 8 to which the anion-concentrated water is supplied is provided with a non-ion permeable anode electrode 3 (anode non-porous ceramic membrane), and the ion-permeable cathode electrode 2 (cathode-porous ceramic membrane) and The non-ion permeable anode electrode 3 is disposed so as to be opposed to each other with the spacer S interposed therebetween, and a current is allowed to flow therebetween, and the ion-permeable cathode electrode 2 is further impregnated to reduce or even remove the anion. Pooled to the central water collection pipe P.
由於在陽極電極與陰極電極之間發生了電解，因此由此產生的次氯酸和．OH基的強力氧化作用就能將廢水中的污物成分(被氧化物質)加以分解，並且能夠同時進行對廢水的脫鹽和淡水化以及對廢水中污物的分解和淨化。Since electrolysis occurs between the anode electrode and the cathode electrode, the resulting hypochlorous acid and. The strong oxidation of the OH group can decompose the pollutant components (oxidized substances) in the wastewater, and simultaneously perform desalting and desalination of the wastewater and decomposition and purification of the waste water.
本實施形態是將離子滲透性的陽極電極與離子滲透性的陰極電極層疊，且將滲透它們雙方的水匯集(圖中未示)，能夠將陽離子和陰離子依次過濾而使它們減少乃至被除去。而陽離子和陰離子哪個先過濾都可以。In the present embodiment, an ion-permeable anode electrode and an ion-permeable cathode electrode are laminated, and water which permeates both of them is collected (not shown), and cations and anions can be sequentially filtered to reduce or remove them. Which of the cations and anions can be filtered first.
由於不施加高壓也能進行過濾，因此適用於各種過濾機構。Since it can be filtered without applying high pressure, it is suitable for various filter mechanisms.
