Pamene kafukufuku akupita patsogolo, ukadaulo wopangira madzi otayira m'mafakitale pogwiritsa ntchito iron-carbon microelectrolysis wakula kwambiri. Ukadaulo wa Microelectrolysis ukuchulukirachulukira pochiza madzi owonongeka a mafakitale ndipo wapeza kugwiritsidwa ntchito kofala muzochita zauinjiniya.
Mfundo ya microelectrolysis ndiyosavuta; imagwiritsa ntchito dzimbiri zazitsulo kupanga ma electrochemical cell poyeretsa madzi oyipa. Njirayi imagwiritsa ntchito zinyalala zachitsulo ngati zopangira, zosafunikira kugwiritsa ntchito zinthu zamagetsi, motero, imaphatikizapo lingaliro la "kuwononga zinyalala." Makamaka, mu gawo lamkati la electrolytic la microelectrolysis process, zinthu monga zinyalala zachitsulo zotayidwa ndi kaboni wokhala ndi activated nthawi zambiri zimagwiritsidwa ntchito ngati zodzaza. Kupyolera mu zochitika za mankhwala, kuchepetsa kwambiri Fe2+ ma ion amapangidwa, omwe amatha kuchepetsa zigawo zina m'madzi onyansa omwe ali ndi okosijeni.
Kuphatikiza apo, Fe(OH) 2 itha kugwiritsidwa ntchito pophatikizana pochiza madzi, ndipo kaboni woyamwa ali ndi mphamvu zotsatsira, kuchotsa bwino ma organic compounds ndi tizilombo tating'onoting'ono. Chifukwa chake, microelectrolysis imaphatikizapo kupanga mphamvu yamagetsi yofooka kudzera mu cell-carbon electrochemical cell, yomwe imathandizira kukula ndi kagayidwe kake. Ubwino waukulu wa njira yochizira madzi ya electrolysis ndikuti sichimawononga mphamvu ndipo imatha kuchotsa nthawi imodzi zoipitsa ndi mitundu yosiyanasiyana m'madzi onyansa ndikuwongolera kuwonongeka kwa zinthu za recalcitrant. Ukadaulo woyeretsera madzi wa Microelectrolysis nthawi zambiri umagwiritsidwa ntchito ngati njira yopangirapo kale kapena yowonjezera molumikizana ndi njira zina zoyeretsera madzi kuti madzi asamawonongeke komanso kuti asawonongeke. Komabe, ilinso ndi zovuta zake, pomwe cholepheretsa chachikulu ndicho kuchedwetsa kachitidwe, kutsekeka kwa ma reactor, ndi zovuta pakutsuka madzi owonongeka omwe ali ndi kuchuluka kwambiri.
Poyambirira, ukadaulo wa iron-carbon microelectrolysis udagwiritsidwa ntchito pochiza utoto ndi kusindikiza madzi onyansa, zomwe zimabweretsa zotsatira zabwino. Kuonjezera apo, kafukufuku wochuluka ndi ntchito zakhala zikuchitika pochiza madzi onyansa omwe ali ndi organic kuchokera ku mapepala, mankhwala, kuphika, mchere wambiri wamchere, electroplating, petrochemicals, madzi onyansa okhala ndi mankhwala ophera tizilombo, komanso madzi oipa omwe ali ndi arsenic ndi cyanide. Pochiza madzi owonongeka achilengedwe, microelectrolysis sikuti imangochotsa zinthu zachilengedwe komanso imachepetsa COD ndikuwonjezera kuwonongeka kwachilengedwe. Imathandizira kuchotsedwa kwamagulu a okosijeni m'magulu achilengedwe kudzera pa adsorption, coagulation, chelation, ndi electro-deposition, ndikupanga mikhalidwe yabwino kuti ipitirire chithandizo.
Pakugwiritsa ntchito, iron-carbon microelectrolysis yawonetsa zabwino zazikulu komanso chiyembekezo chodalirika. Komabe, nkhani monga kutsekeka ndi kuwongolera pH zimachepetsa kupititsa patsogolo kwa njirayi. Akatswiri azachilengedwe akuyenera kuchita kafukufuku wowonjezera kuti apange mikhalidwe yabwino kwambiri yogwiritsira ntchito ukadaulo wa iron-carbon microelectrolysis pakuthana ndi madzi otayira m'mafakitale akuluakulu.
