Inkqubo yemveliso

Itekhnoloji ye-EDI yinkqubo entsha ye-desalination edibanisa i-electrodialysis kunye ne-ion exchange.Le nkqubo ithatha inzuzo yamandla kokubili kwe-electrodialysis kunye ne-ion exchange kwaye ihlawule ubuthathaka babo.Isebenzisa utshintshiselwano lwe-ion ukuya kwi-desalinate enzulu ukuze inqobe ingxaki yokukhutshwa kwetyuwa engaphelelanga okubangelwa yi-electrodialysis polarization.Ikwasebenzisa i-electrodialysis polarization ukuvelisa i-H+ kunye ne-OH- ion yokuvuselela i-resin ngokuzenzekelayo, eyoyisa ukungonakali kokuhlaziywa kweekhemikhali emva kokungaphumeleli kwe-resin.Ke ngoko, itekhnoloji ye-EDI yinkqubo egqibeleleyo yokususa ityuwa emanzini.

Ngexesha lenkqubo ye-EDI yokukhupha ityuwa emanzini, ii-ion emanzini zitshintshwa kunye ne-hydrogen ion okanye i-hydroxide ion kwi-ion exchange resin, kwaye ke ezi ion zifudukela emanzini agxininisiweyo.Oku kutshintshiselana kwe-ion kwenzeka kwigumbi lokuxutywa lamanzi leyunithi.Kwigumbi le-dilute lamanzi, ii-ion ze-hydroxide kwi-anion exchange resin exchange kunye nee-anions ezisemanzini, kunye ne-hydrogen ion kwi-cation exchange resin exchange kunye neecations emanzini.Iiyoni ezitshintshiweyo emva koko zifuduka ecaleni komphezulu weebhola ze-resin phantsi kwesenzo sombane we-DC kwaye zingene kwigumbi eligxininisiweyo lamanzi ngokutshintshiselana kwe-ion.

I-anion ehlawulwe kakubi itsalwa kwi-anode kwaye ingene kwigumbi elidibeneyo lamanzi ngenwebu ye-anion, ngelixa i-membrane ye-cation ekufutshane ibathintela ukuba badlule kwaye ibhloko ezi ion emanzini agxininiswe.Iications ezichajiwe kakuhle zitsalwa kwi-cathode kwaye zingena kwigumbi lamanzi elisondeleyo ngenwebu ye-cation, ngelixa i-anion inwebu esecaleni iyabathintela ukuba badlule kwaye ibhloke ezi ion emanzini agxininiswe.

Emanzini agxininisiweyo, ii-ion ezivela kumacala omabini zigcina ukungathathi hlangothi kombane.Okwangoku, ukufuduka kwangoku kunye ne-ion kuhambelana, kwaye okwangoku kukho iinxalenye ezimbini.Enye inxalenye ivela ekufudukeni kwee-ion ezisusiweyo, kwaye enye inxalenye ivela ekufudukeni kwee-ion zamanzi ezi-ionize zibe yi-H + kunye ne-OH-ions.Xa amanzi edlula emanzini e-dilute kunye namagumbi agxininiswe amanzi, i-ion ingena ngokuthe ngcembe kwindawo edibeneyo yamanzi kwaye iqhutywe ngaphandle kweyunithi ye-EDI ngamanzi agxininisiweyo.

Ngaphantsi kwe-gradient yombane ophezulu, amanzi ahlanjululwa nge-electrolyzed ukuvelisa inani elikhulu le-H + kunye ne-OH-, kwaye ezi ndawo zivelise i-H + kunye ne-OH- ngokuqhubekayo zihlaziya i-ion exchange resin.Ngoko ke, i-ion exchange resin kwiyunithi ye-EDI ayifuni ukuhlaziywa kweekhemikhali.Le yinkqubo ye-EDI yokukhutshwa kwetyuwa emanzini.

Iimpawu zobugcisa

1. Inokuvelisa amanzi ngokuqhubekayo, kwaye ukuxhathisa kwamanzi avelisiweyo kuphezulu, ukusuka kwi-15MΩ.cm ukuya kwi-18MΩ.cm.
2. Izinga lokuvelisa amanzi lingafikelela ngaphezu kwe-90%.
3. Umgangatho wamanzi oveliswayo uzinzile kwaye awufuni ukuhlaziywa kwe-acid-base.
4. Akukho manzi amdaka aveliswayo kwinkqubo.
5. Ulawulo lwenkqubo luzenzekelayo kakhulu, kunye nokusebenza okulula kunye nokusebenza okuphantsi.T

Iimfuno eziphambili

1. Amanzi okutya kufuneka abe yi-RO eveliswa ngamanzi kunye ne-conductivity ye-≤20μs / cm (kucetyiswa ukuba ibe <10μs / cm).
2. Ixabiso le-pH kufuneka libe phakathi kwe-6.0 kunye ne-9.0 (kucetyiswa ukuba ibe phakathi kwe-7.0 kunye ne-9.0).
3. Ubushushu bamanzi kufuneka bube phakathi kwe 5 kunye ne 35℃.
4. Ukuqina (kubalwe njenge-CaCO3) kufuneka kube ngaphantsi kwe-0.5 ppm.
5. I-organic matter kufuneka ibe ngaphantsi kwe-0.5 ppm, kwaye ixabiso le-TOC linconywa ukuba libe yi-zero.
6. Ii-oxidants kufuneka zibe ngaphantsi okanye zilingane no-0.05 ppm (Cl2) kunye no-0.02 ppm (O3), zombini zibe ngu-zero njengeyona meko iphezulu.
7. Uxinzelelo lwe-Fe kunye no-Mn kufuneka lube ngaphantsi okanye lulingane no-0.01 ppm.
8. Uxinzelelo lwe-silicon dioxide kufuneka lube ngaphantsi kwe-0.5 ppm.
9. Uxinzelelo lwe-carbon dioxide kufuneka lube ngaphantsi kwe-5 ppm.
Akukho mafutha okanye amafutha kufuneka abonwe.
