Lefatšeng, ntho e 'ngoe le e' ngoe e na le melemo le boiketlo ba eona. Khatelo-pele ea sechaba le ntlafatso ea maemo a bophelo a batho li lebisa tšilafalong ea tikoloho. Metsi a litšila ke taba e 'ngoe e joalo. Ka tsoelo-pele e potlakileng ea liindasteri tse kang tsa petrochemicals, masela, ho etsa pampiri, chefo e bolaeang likokoanyana, meriana, metallurgy le tlhahiso ea lijo, kakaretso ea metsi a litšila e eketsehile haholo lefatšeng ka bophara. Ho feta moo, metsi a litšila hangata a na le lintho tse ngata, chefo e ngata, letsoai le lengata, le likarolo tsa mebala e phahameng, e leng ho etsang hore ho be thata ho theola le ho alafa, e leng se lebisang tšilafalong e matla ea metsi.
E le ho sebetsana le metsi a mangata a litšila a fehloang letsatsi le letsatsi, batho ba ’nile ba sebelisa mekhoa e sa tšoaneng, e kopanyang mekhoa ea ’mele, ea lik’hemik’hale le ea baeloji, hammoho le ho sebelisa matla a kang motlakase, molumo, khanya le makenete. Sehlooho sena se akaretsa tšebeliso ea "motlakase" ka theknoloji ea phekolo ea metsi ea electrochemical ho rarolla bothata bona.
Theknoloji ea kalafo ea metsi ea electrochemical e bolela ts'ebetso ea ho silafatsa litšila ka metsing a litšila ka karabelo e ikhethileng ea electrochemical, lits'ebetso tsa electrochemical, kapa lits'ebetso tsa 'mele ka har'a mochini o itseng oa electrochemical, tlas'a tšusumetso ea li-electrode kapa sebaka sa motlakase se sebelisitsoeng. Sistimi ea electrochemical le lisebelisoa li batla li le bonolo, li nka sebaka se senyenyane, li na le litšenyehelo tse tlase tsa ts'ebetso le tlhokomelo, li thibela ka nepo tšilafalo ea bobeli, li fana ka taolo e phahameng ea karabelo, 'me li thusa ho iketsetsa liindasteri, ho ba fa lengolo la theknoloji ea "botsoalle ba tikoloho".
Theknoloji ea phekolo ea metsi ea electrochemical e kenyelletsa mekhoa e fapaneng e kang electrocoagulation-electroflotation, electrodialysis, electroadsorption, electro-Fenton, le electrocatalytic advanced oxidation. Mekhoa ena e fapane 'me e' ngoe le e 'ngoe e na le lisebelisoa le libaka tsa eona tse loketseng.
Electrocoagulation-Electroflotation
Electrocoagulation, ha e le hantle, ke electroflotation, kaha mokhoa oa ho kopanya o etsahala ka nako e le 'ngoe le ho phalla. Ka hona, e ka bitsoa "electrocoagulation-electroflotation" ka kakaretso.
Mokhoa ona o itšetlehile ka ts'ebeliso ea motlakase oa kantle oa motlakase, o hlahisang li-cations tse qhibilihang ho anode. Li-cations tsena li na le phello e kopanyang linthong tse silafatsang tsa colloidal. Ka nako e le 'ngoe, palo e kholo ea khase ea haedrojene e hlahisoa ka har'a cathode tlas'a tšusumetso ea motlakase, e thusang hore lintho tse entsoeng ka flocculated li phahame holimo. Ka tsela ena, electrocoagulation e fihlella karohano ea litšila le tlhoekiso ea metsi ka anode coagulation le cathode flotation.
Ho sebelisa tšepe e le anode e qhibilihang (hangata aluminium kapa tšepe), li-ion tsa Al3+ kapa Fe3+ tse hlahisoang nakong ea electrolysis li sebetsa e le li-electroactive coagulants. Li-coagulants tsena li sebetsa ka ho hatella lera la colloidal habeli, ho le senya, le ho koala le ho hapa likaroloana tsa colloidal ka:
Al -3e→ Al3+ kapa Fe -3e→ Fe3+
Al3+ + 3H2O → Al(OH)3 + 3H+ kapa 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-
Ka lehlakoreng le leng, electroactive coagulant M(OH)n e bitsoa soluble polymeric hydroxo complexes 'me e sebetsa e le flocculant ho kopanya ka potlako le ka katleho li-colloidal suspensions (marotholi a matle a oli le litšila tse sebetsang) metsing a litšila ha a ntse a li koala le ho li hokahanya hore li thehe. likarolo tse kholoanyane, ho potlakisa ts'ebetso ea karohano. Ka lehlakoreng le leng, li-colloids li hatelloa tlas'a tšusumetso ea li-electrolyte tse kang aluminium kapa letsoai la tšepe, tse lebisang ho coagulation ka phello ea Coulombic kapa adsorption ea coagulants.
Le hoja ts'ebetso ea electrochemical (lifespan) ea li-coagulants tsa electroactive e le metsotso e seng mekae feela, li ama haholo matla a mabeli a lera, kahoo li fana ka liphello tse matla tsa coagulation ho likaroloana tsa colloidal kapa likaroloana tse emisitsoeng. Ka lebaka leo, matla a bona a adsorption le ts'ebetso ea bona e phahame haholo ho feta mekhoa ea lik'hemik'hale e kenyelletsang ho eketsoa ha li-reagents tsa letsoai tsa aluminium, 'me li hloka chelete e nyenyane' me li na le litšenyehelo tse tlaase. Electrocoagulation ha e amehe ke maemo a tikoloho, mocheso oa metsi, kapa litšila tsa likokoana-hloko, 'me ha e kenelle ka lehlakoreng le nang le letsoai la aluminium le metsi a hydroxides. Ka hona, e na le mefuta e mengata ea pH bakeng sa ho hloekisa metsi a litšila.
Ho phaella moo, ho lokolloa ha li-bubble tse nyenyane holim'a cathode ho potlakisa ho thulana le ho arohana ha li-colloid. Electro-oxidation e ka holim'a anode le electro-oxidation e sa tobang ea Cl- into e sebetsang ea chlorine li na le matla a matla a oxidative linthong tse qhibilihang ka har'a lintho tse phelang le lintho tse fokotsehang tsa inorganic ka metsing. Hydrogen e sa tsoa hlahisoa ho tsoa ho cathode le oksijene e tsoang ho anode e na le matla a matla a redox.
Ka lebaka leo, lits'ebetso tsa lik'hemik'hale tse etsahalang ka har'a mochini oa electrochemical li rarahane haholo. Lits'ebetsong tsa motlakase, electrocoagulation, electroflotation, le electrooxidation kaofela li etsahala ka nako e le 'ngoe, ka katleho li fetola le ho tlosa li-colloid tse qhibilihisitsoeng le litšila tse emisitsoeng metsing ka ho kopana, ho phalla le ho ntša oxidation.
