Njengoba ucwaningo luqhubeka, ubuchwepheshe bokwelapha amanzi angcolile asezimbonini kusetshenziswa i-iron-carbon microelectrolysis sebukhulile kakhulu. Ubuchwepheshe be-microelectrolysis buya ngokuya bukhula ekwelapheni amanzi angcolile asezimbonini angasasebenzi futhi sebusetshenziswe kabanzi emisebenzini yobunjiniyela.
Isimiso se-microelectrolysis silula kakhulu; sisebenzisa ukugqwala kwezinsimbi ukudala amaseli e-electrochemical okwelapha amanzi amdaka. Le ndlela isebenzisa izingcezu zensimbi ezingafuneki njengezinto zokusetshenziswa, okungadingi ukusetshenziswa kwezinsiza zikagesi, ngakho-ke, imelela umqondo "wokuphatha imfucuza ngemfucuza." Ngokukhethekile, kukholomu yangaphakathi ye-electrolytic yenqubo ye-microelectrolysis, izinto ezifana nezingcezu zensimbi ezingafuneki kanye ne-activated carbon zivame ukusetshenziswa njengezigcwalisi. Ngokusebenzisa ukusabela kwamakhemikhali, kukhiqizwa ama-ion e-Fe2+ anciphayo anamandla, anganciphisa izingxenye ezithile emanzini amdaka anezakhiwo ze-oxidative.
Ngaphezu kwalokho, i-Fe(OH)2 ingasetshenziswa ekuhlanganiseni amanzi, futhi ikhabhoni esebenzayo inamandla okumunca, isusa ngempumelelo amakhemikhali e-organic kanye nama-microorganism. Ngakho-ke, i-microelectrolysis ihilela ukukhiqizwa kogesi obuthakathaka ngeseli le-electrochemical le-iron-carbon, elikhuthaza ukukhula kanye nokusetshenziswa kwe-metabolism yama-microorganism. Inzuzo ebalulekile yendlela yokwelapha amanzi nge-electrolysis yangaphakathi ukuthi ayisebenzisi amandla futhi ingasusa ngasikhathi sinye ukungcola okuhlukahlukene nombala emanzini angcolile ngenkathi ithuthukisa ukubola kwezinto ezibolayo. Ubuchwepheshe bokwelapha amanzi nge-microelectrolysis buvame ukusetshenziswa njengendlela yokwelapha ngaphambi kokwelashwa noma indlela eyengeziwe ngokubambisana nezinye izindlela zokwelashwa kwamanzi ukuthuthukisa ukubola kwamanzi angcolile. Kodwa-ke, futhi inezinkinga, kanye nokungalungi okukhulu amazinga okusabela ahamba kancane, ukuvaleka kwe-reactor, kanye nezinselele ekwelapheni amanzi angcolile anokugcwala okuphezulu.
Ekuqaleni, ubuchwepheshe be-microelectrolysis ye-iron-carbon basetshenziswa ekwelapheni ukudaya nokuphrinta amanzi angcolile, kwaveza imiphumela emihle. Ngaphezu kwalokho, kwenziwe ucwaningo olunzulu kanye nokusetshenziswa ekwelapheni amanzi angcolile acebile ngezinto eziphilayo avela ekwenzeni iphepha, emithi, ekuphekeni, emanzini angcolile aqukethe usawoti omningi, ekufakeni i-electroplating, emakhemikhali kaphethroli, emanzini angcolile aqukethe izibulala-zinambuzane, kanye namanzi angcolile aqukethe i-arsenic ne-cyanide. Ekwelapheni amanzi angcolile angokwemvelo, i-microelectrolysis ayisusi nje kuphela izinto eziphilayo kodwa futhi inciphisa i-COD futhi ithuthukise ukubola kwezinto eziphilayo. Isiza ekususweni kwamaqembu e-oxidative ezinhlanganisela zezinto eziphilayo ngokumunca, ukujiya, i-chelation, kanye nokufakwa kwe-electro, okudala izimo ezinhle zokwelashwa okwengeziwe.
Ekusetshenzisweni okungokoqobo, i-iron-carbon microelectrolysis ibonise izinzuzo ezibalulekile kanye namathuba athembisayo. Kodwa-ke, izinkinga ezifana nokuvaleka kanye nokulawulwa kwe-pH zikhawulela intuthuko eyengeziwe yale nqubo. Ochwepheshe bezemvelo badinga ukwenza ucwaningo olwengeziwe ukuze badale izimo ezinhle kakhulu zokusetshenziswa kobuchwepheshe be-iron-carbon microelectrolysis ekwelapheni amanzi angcolile ezimbonini ezinkulu.
