amazi yo mu nyanja gutunganya amazi amazi ro sisitemu Yakozwe

Igicuruzwa

Ikoranabuhanga rya EDI ni uburyo bushya bwo gusibanganya guhuza electrodialysis no guhana ion.Iyi nzira yifashisha imbaraga zombi za electrodialysis no guhana ion kandi ikishyura intege nke zabo.Ikoresha ion guhana kugirango yanduze cyane kugirango ikemure ikibazo cyo gusiba kutuzuye guterwa na electrodialysis polarisation.Ikoresha kandi polarisiyasi ya electrodialysis kugirango itange H + na OH- ion zo kuvugurura ibyuma byikora, bikanesha ingaruka mbi zo kuvugurura imiti nyuma yo kunanirwa.Kubwibyo, tekinoroji ya EDI ninzira nziza yo gusiba.

Mugihe cyo gukuramo EDI, ion mumazi ihanahana na hydrogène ion cyangwa hydroxide ion mumashanyarazi ya ion, hanyuma izo ion zikimukira mumazi yibanze.Iyi ion yo guhanahana iboneka mubyumba byamazi byamazi byigice.Mu cyumba cyamazi cyamazi, hydroxide ion muri anion yo guhana resin ihinduranya hamwe na anion mumazi, hamwe na hydrogène ion muguhana cation guhana hamwe na cations mumazi.Ion zahinduwe noneho zimuka hejuru yumupira wa resin munsi yumuriro wamashanyarazi ya DC hanyuma winjire mucyumba cyamazi cyibanze binyuze mu guhana ion.

Anion zishizwemo nabi zikururwa na anode hanyuma zinjira mucyumba cy’amazi cyegeranye binyuze muri anion membrane, mugihe cation membrane yegeranye ibabuza kunyura no guhagarika izo ion mumazi yibanze.Cations zashizwemo neza zikururwa na cathode hanyuma zinjira mucyumba cy’amazi cyegeranye cyanyuze muri cation membrane, mugihe anion membrane yegeranye ibabuza kunyura no guhagarika izo ion mumazi yibanze.

Mu mazi yibanze, ion ziva mubyerekezo byombi zigumana kutabogama kwamashanyarazi.Hagati aho, ikigezweho na ion kwimuka biragereranijwe, kandi ibyubu bigizwe nibice bibiri.Igice kimwe kiva mu kwimuka kwa ion zavanyweho, ikindi gice kiva mu kwimuka kwa ion zamazi zinjira muri H + na OH- ion.Iyo amazi anyuze mumazi yoroheje hamwe nibyumba byamazi byegeranye, ion zinjira buhoro buhoro mucyumba cy’amazi cyegeranye kandi bigakorerwa mu gice cya EDI hamwe n’amazi yibanze.

Munsi ya voltage nini cyane, amazi arashiramo amashanyarazi kugirango atange umusaruro mwinshi wa H + na OH-, kandi ibyo bibera aho byabyaye H + na OH- bikomeza kuvugurura ion ihinduranya.Kubwibyo, ion guhana resin mubice bya EDI ntibisaba kuvugurura imiti.Nibikorwa bya EDI.

Ibiranga tekinike

1. Irashobora gutanga amazi ubudahwema, kandi irwanya amazi yakozwe ni menshi, kuva kuri 15MΩ.cm kugeza 18MΩ.cm.
2. Igipimo cy’amazi gishobora kugera hejuru ya 90%.
3. Ubwiza bwamazi yakozwe butajegajega kandi ntibusaba kuvugurura aside-ishingiro.
4. Nta mazi mabi atangwa muri gahunda.
5. Igenzura rya sisitemu ryikora cyane, hamwe nibikorwa byoroshye nubushobozi buke bwabakozi.T

Ibisabwa byambere

1. Amazi yo kugaburira agomba kuba amazi yakozwe na RO afite ubushobozi bwa ≤20μs / cm (bisabwa kuba <10μs / cm).
2. Agaciro pH kagomba kuba hagati ya 6.0 na 9.0 (bisabwa kuba hagati ya 7.0 na 9.0).
3. Ubushyuhe bwamazi bugomba kuba hagati ya 5 na 35 ℃.
4. Gukomera (kubarwa nka CaCO3) bigomba kuba munsi ya 0.5 ppm.
5. Ibintu kama bigomba kuba munsi ya 0.5 ppm, kandi agaciro ka TOC karasabwa kuba zeru.
6. Okiside igomba kuba munsi cyangwa ingana na 0.05 ppm (Cl2) na 0.02 ppm (O3), byombi bikaba zeru nkibintu byiza.
7. Ibitekerezo bya Fe na Mn bigomba kuba munsi cyangwa bingana na 0.01 ppm.
8. Ubwinshi bwa dioxyde de silicon igomba kuba munsi ya 0.5 ppm.
9. Ubwinshi bwa karuboni ya dioxyde igomba kuba munsi ya 5 ppm.
Nta mavuta cyangwa ibinure bigomba kuboneka.
