amanzi olwandle isitshalo sokuhlanza amanzi amanzi ro uhlelo Umkhiqizi

Inqubo yomkhiqizo

Ubuchwepheshe be-EDI wuhlelo olusha lokukhipha usawoti emanzini oluhlanganisa i-electrodialysis kanye nokushintshisana kwe-ion.Le nqubo isebenzisa amandla akho kokubili i-electrodialysis kanye nokushintshisana kwe-ion futhi inxephezela ubuthakathaka bazo.Isebenzisa ukushintshaniswa kwe-ion ukuze ikhiphe usawoti ejulile ukuze inqobe inkinga yokukhipha usawoti emanzini okungaphelele okubangelwa i-electrodialysis polarization.Iphinde isebenzise i-electrodialysis polarization ukuze ikhiqize i-H+ kanye ne-OH- ion ukuze ikhiqize kabusha i-resin ezenzakalelayo, enqoba ububi bokuvuselelwa kwamakhemikhali ngemva kokuhluleka kwe-resin.Ngakho-ke, ubuchwepheshe be-EDI buyindlela ephelele yokukhipha usawoti emanzini.

Ngesikhathi senqubo ye-EDI yokukhipha usawoti emanzini, ama-ion emanzini ashintshaniswa nama-ion e-hydrogen noma ama-ion e-hydroxide ku-resin yokushintshanisa i-ion, bese lama-ion efudukela emanzini agxilile.Lokhu kusabela kokushintshana kwe-ion kwenzeka ekamelweni lamanzi elixutshiwe leyunithi.Egunjini lamanzi acwebileyo, ama-ion e-hydroxide ekushintshanisweni kwenhlaka ye-anion nama-anion emanzini, nama-ion e-hydrogen ekushintshisaneni kwenhlaka ye-cation nama-cation emanzini.Ama-ion ashintshiwe abe esehamba phezu kwamabhola e-resin ngaphansi kwesenzo se-DC kagesi yamanje bese engena egumbini eligxilile lamanzi ngokushintshana kwe-ion.

Ama-anion anamacala angalungile akhangwa ku-anode futhi angena egunjini lamanzi agxilile eliseduze ngolwelwesi lwe-anion, kuyilapho ulwelwesi oluseduze lwe-cation lubavimbela ukuba badlule futhi luvimbe la ma-ion emanzini agxilile.Ama-cations ashajwe kahle akhangwa ku-cathode futhi angena egunjini lamanzi agxilile eliseduze ngolwelwesi lwe-cation, kuyilapho ulwelwesi lwe-anion oluseduze luwavimbela ukuba angadluli futhi luvimbe la ma-ion emanzini agxilile.

Emanzini agxilile, ama-ion asuka kuzo zombili izinkomba agcina ukungathathi hlangothi kukagesi.Phakathi naleso sikhathi, ukufuduka kwamanje kanye ne-ion kuyalingana, futhi okwamanje kuqukethe izingxenye ezimbili.Ingxenye eyodwa iphuma ekufudukeni kwama-ion akhishiwe, kanti enye ingxenye isuka ekufudukeni kwama-ion amanzi angena ku-H+ naku-OH- ions.Lapho amanzi edlula emanzini ahlanjululwe kanye namakamelo amanzi agxilile, ama-ion kancane kancane angena ekamelweni eligxilile lamanzi futhi aphuma kuyunithi ye-EDI ngamanzi ahlanganisiwe.

Ngaphansi kwe-gradient ye-voltage ephezulu, amanzi afakwa ngogesi ukuze akhiqize inani elikhulu le-H+ ne-OH-, futhi lawa esizeni akhiqiza i-H+ ne-OH- ngokuqhubekayo enza kabusha inhlaka yokushintshanisa ion.Ngakho-ke, i-ion exchange resin kuyunithi ye-EDI ayidingi ukuvuselelwa kwamakhemikhali.Lena inqubo ye-EDI yokukhipha usawoti emanzini.

Izici zobuchwepheshe

1. Ingakwazi ukukhiqiza amanzi ngokuqhubekayo, futhi ukumelana kwamanzi akhiqizwayo kuphezulu, kusukela ku-15MΩ.cm kuya ku-18MΩ.cm.
2. Izinga lokukhiqiza amanzi lingafinyelela ngaphezu kwama-90%.
3. Izinga lamanzi elikhiqizwayo lizinzile futhi alidingi ukuvuselelwa kwe-acid-base.
4. Awekho amanzi angcolile akhiqizwayo.
5. Ukulawulwa kwesistimu ku-othomathikhi kakhulu, ngokusebenza okulula kanye nokuqina okuphansi komsebenzi.T

Izimfuneko eziyinhloko

1. Amanzi okuphakelayo kufanele abe ngamanzi akhiqizwe nge-RO ane-conductivity engu-≤20μs/cm (kunconywe ukuthi abe ngu-<10μs/cm).
2. Inani le-pH kufanele libe phakathi kuka-6.0 no-9.0 (kunconywa ukuthi libe phakathi kuka-7.0 no-9.0).
3. Izinga lokushisa lamanzi kufanele libe phakathi kuka-5 no-35℃.
4. Ukuqina (okubalwa njenge-CaCO3) kufanele kube ngaphansi kuka-0.5 ppm.
5. I-organic matter kufanele ibe ngaphansi kuka-0.5 ppm, futhi inani le-TOC linconywa ukuthi libe nguziro.
6. Ama-oxidants kufanele abe ngaphansi noma alingane no-0.05 ppm (Cl2) kanye no-0.02 ppm (O3), kokubili kube nguziro njengesimo esifanele.
7. Ukugxila kwe-Fe kanye ne-Mn kufanele kube ngaphansi noma kulingane no-0.01 ppm.
8. Ukuhlushwa kwe-silicon dioxide kufanele kube ngaphansi kuka-0.5 ppm.
9. Ukugcwala kwe-carbon dioxide kufanele kube ngaphansi kuka-5 ppm.
Awekho amafutha noma amafutha okufanele abonwe.
