Njengoba ucwaningo luqhubeka, ubuchwepheshe bokwelapha amanzi angcolile ezimbonini kusetshenziswa i-iron-carbon microelectrolysis sebukhule ngokukhula. Ubuchwepheshe be-Microelectrolysis budlondlobala ekwelapheni amanzi angcolile ezimbonini futhi sebuthole ukusetshenziswa okusabalele emisebenzini yobunjiniyela.
Isimiso se-microelectrolysis siqondile; isebenzisa ukugqwala kwezinsimbi ukwakha amaseli e-electrochemical ukuze kuhlanzwe amanzi angcolile. Le ndlela isebenzisa izinsalela zensimbi ezilahlwayo njengezinto ezingavuthiwe, ezingadingi ukusetshenziswa kwezinsiza zikagesi, futhi ngenxa yalokho, ihlanganisa umqondo "wokuphatha imfucuza ngemfucuza." Ngokukhethekile, kukholamu yangaphakathi ye-electrolytic yenqubo ye-microelectrolysis, izinto ezifana nezinsalela zensimbi ezilahlwayo kanye nekhabhoni ecushiwe zivame ukusetshenziswa njengezigcwalisi. Ngokusabela kwamakhemikhali, kukhiqizwa ama-ion e-Fe2+ anamandla ancishiswayo, anganciphisa izingxenye ezithile emanzini angcolile anezakhiwo ze-oxidative.
Ukwengeza, i-Fe(OH)2 ingasetshenziselwa ukujiya ekwelapheni amanzi, futhi ikhabhoni ecushiwe inamandla okukhangisa, isuse ngempumelelo izinhlanganisela zezinto eziphilayo nama-microorganisms. Ngakho-ke, i-microelectrolysis ihilela ukukhiqizwa kwamandla kagesi abuthakathaka ngengqamuzana ye-iron-carbon electrochemical cell, ekhuthaza ukukhula kanye ne-metabolism yama-microorganisms. Inzuzo eyinhloko yendlela yokwelapha amanzi ye-electrolysis yangaphakathi ukuthi ayiwadli amandla futhi ingasusa ngesikhathi esisodwa ukungcola okuhlukahlukene kanye nemibala emanzini angcolile kuyilapho ithuthukisa ukubola kwezinto eziphilayo. Ubuchwepheshe bokuhlanza amanzi nge-Microelectrolysis ngokuvamile busetshenziswa njengendlela yokwelapha ngaphambi kwesikhathi noma njengendlela yokwengeza ngokuhambisana nezinye izindlela zokuhlanza amanzi ukuze kuthuthukiswe ukuphatheka kahle kanye nokubola kwamanzi angcolile. Kodwa-ke, futhi inobubi, ne-drawback enkulu ukuthi ukusabela okunensayo uma kuqhathaniswa, ukuvinjelwa kwe-reactor, kanye nezinselelo zokwelapha amanzi angcolile agxile kakhulu.
Ekuqaleni, ubuchwepheshe be-iron-carbon microelectrolysis babusetshenziswa ekwelapheni ukudaya nokuphrinta amanzi angcolile, kwaveza imiphumela emihle. Ukwengeza, ucwaningo olubanzi kanye nokusetshenziswa kuye kwenziwa ekwelapheni amanzi angcolile anothile nge-organic kusuka ekwenzeni iphepha, imithi, ukupheka, amanzi angcolile anosawoti omningi, i-electroplating, amakhemikhali e-petrochemicals, amanzi angcolile aqukethe izibulala-zinambuzane, kanye namanzi angcolile aqukethe i-arsenic ne-cyanide. Ekwelashweni kwamanzi angcolile, i-microelectrolysis ayisusi nje kuphela izinto eziphilayo kodwa futhi yehlisa i-COD futhi ithuthukise ukubola kwezinto eziphilayo. Isiza ukususwa kwamaqembu e-oxidative kuma-organic compounds nge-adsorption, coagulation, chelation, kanye ne-electro-deposition, okwenza izimo ezivumayo zokwelashwa okwengeziwe.
Ekusetshenzisweni okungokoqobo, i-iron-carbon microelectrolysis ibonise izinzuzo ezibalulekile namathemba athembisayo. Kodwa-ke, izingqinamba ezinjengokuvaleka kanye nokulawulwa kwe-pH zikhawulela ukuthuthuka okuqhubekayo kwale nqubo. Ochwepheshe bezemvelo badinga ukwenza ucwaningo olwengeziwe ukuze benze izimo ezivumayo zokusetshenziswa kobuchwepheshe be-iron-carbon microelectrolysis ekwelashweni kwamanzi angcolile ezimbonini ezinkulu.
