Mokhoa oa lihlahisoa

Theknoloji ea EDI ke mokhoa o mocha oa ho tlosa letsoai letsoai o kopanyang electrodialysis le phapanyetsano ea ion.Ts'ebetso ena e nka monyetla ka matla a electrodialysis le phapanyetsano ea ion mme e lefella mefokolo ea bona.E sebelisa phapanyetsano ea ion ho desalinate e tebileng ho hlola bothata ba ho tlosa letsoai ka botlalo ho bakoang ke polarization ea electrodialysis.E boetse e sebelisa polarization ea electrodialysis ho hlahisa H+ le OH- ion bakeng sa ho nchafatsa resin ka boiketsetso, e hlolang bobe ba ho nchafatsa lik'hemik'hale kamora ho hloleha ha resin.Ka hona, theknoloji ea EDI ke mokhoa o phethahetseng oa ho tlosa letsoai.

Nakong ea ts'ebetso ea EDI ea ho ntša letsoai metsing, li-ion tse metsing li fapanyetsana le li-ion tsa hydrogen kapa hydroxide ion ka har'a resin ea ion exchange, ebe li-ion tsena li fallela metsing a kopaneng.Karabelo ena ea phapanyetsano ea ion e etsahala ka phapusing ea metsi e hlapollang ea yuniti.Ka phaposing e hlapollang ea metsi, li-ion tsa hydroxide ka har'a phapanyetsano ea resin ea anion le li-anion tse metsing, le li-ion tsa haedrojene ka phapanyetsano ea resin ea cation le li-cation tse ka metsing.Li-ion tse fapanyetsanoang li falla ka holim'a libolo tsa resin tlas'a ts'ebetso ea motlakase oa motlakase oa DC ebe li kena ka kamoreng ea metsi a mangata ka phapanyetsano ea ion.

Li-anion tse qosoang hampe li hoheloa ke anode 'me li kena ka phaposing ea metsi e kopaneng e haufi ka lera la anion, ha lera la cation le haufi le li thibela ho feta le ho thibela li-ion tsena metsing a kopaneng.Li-cations tse qosoang hantle li hoheloa ke cathode ebe li kena ka phaposing ea metsi e kopaneng e haufi ka lera la cation, ha lera la anion le haufi le li thibela ho feta le ho thibela li-ion tsena metsing a kopaneng.

Ka metsing a teteaneng, li-ion tse tsoang mahlakoreng ka bobeli li boloka ho se nke lehlakore ha motlakase.Ho sa le joalo, ho falla ha hona joale le ion hoa lekana, 'me hona joale ho na le likarolo tse peli.Karolo e 'ngoe e tsoa ho falla ha li-ion tse tlositsoeng,' me karolo e 'ngoe e tsoa ho falla ha li-ion tsa metsi tse kenang ho H+ le OH-ions.Ha metsi a feta ka har'a metsi a hlapollotsoeng le liphaposi tse nang le metsi a mangata, li-ion butle-butle li kena ka kamoreng e haufi ea metsi 'me li tsoa karolong ea EDI ka metsi a teteaneng.

Tlas'a matla a phahameng a motlakase, metsi a etsoa ka motlakase ho hlahisa palo e kholo ea H+ le OH-, 'me tsena tse setšeng li hlahisa H+ le OH- li tsoela pele ho nchafatsa resin ea ion exchange.Ka hona, resin ea phapanyetsano ea ion karolong ea EDI ha e hloke ho tsosolosoa ha lik'hemik'hale.Ena ke ts'ebetso ea EDI desalination.

Likarolo tsa tekheniki

1. E ka hlahisa metsi ka ho tsoelang pele, 'me ho hanyetsa ha metsi a hlahisoang ho phahame, ho tloha ho 15MΩ.cm ho ea ho 18MΩ.cm.
2. Sekhahla sa tlhahiso ea metsi se ka fihla ho feta 90%.
3. Boleng ba metsi bo hlahisoang bo tsitsitse 'me ha bo hloke ho tsosolosoa ha acid-base.
4. Ha ho na metsi a litšila a hlahisoang ts'ebetsong.
5. Tsamaiso ea tsamaiso e sebetsa haholo, e nang le ts'ebetso e bonolo le matla a tlaase a mosebetsi.T

2. Theko ea pH e lokela ho ba pakeng tsa 6.0 le 9.0 (e khothaletsoa ho ba pakeng tsa 7.0 le 9.0).
3. Mocheso oa metsi o lokela ho ba pakeng tsa 5 le 35℃.
4. Ho thatafala (ho baloang e le CaCO3) ho lokela ho ba ka tlase ho 0.5 ppm.
5. Lintho tse phelang li lokela ho ba ka tlaase ho 0.5 ppm, 'me boleng ba TOC bo khothaletsoa ho ba zero.
6. Li-oxidants li lokela ho ba ka tlase ho kapa ho lekana le 0.05 ppm (Cl2) le 0.02 ppm (O3), 'me ka bobeli e be zero e le boemo bo nepahetseng.
