Emhlabeni, konke kunezinzuzo nezinkinga zako. Intuthuko yomphakathi kanye nokuthuthukiswa kwezindinganiso zokuphila zabantu kuholela ekungcolisweni kwemvelo ngokungenakugwenywa. Amanzi angcolile angenye yezinkinga ezinjalo. Ngokuthuthuka okusheshayo kwezimboni ezifana namakhemikhali kaphethiloli, izindwangu, ukwenza amaphepha, izibulala-zinambuzane, imithi, i-metallurgy, kanye nokukhiqizwa kokudla, ukukhishwa kwamanzi angcolile kukhuphuke kakhulu emhlabeni jikelele. Ngaphezu kwalokho, amanzi angcolile avame ukuba namazinga aphezulu, ubuthi obuphezulu, usawoti omningi, kanye nezingxenye ezinombala ophezulu, okwenza kube nzima ukuwabolisa nokwelapha, okuholela ekungcolisweni kwamanzi okukhulu.
Ukuze babhekane nenani elikhulu lamanzi angcolile ezimbonini akhiqizwa nsuku zonke, abantu basebenzise izindlela ezahlukene, behlanganisa izindlela ezingokoqobo, zamakhemikhali, nezebhayoloji, kanye nokusebenzisa amandla anjengogesi, umsindo, ukukhanya, kanye nemagnetism. Lesi sihloko sifingqa ukusetshenziswa "kukagesi" kubuchwepheshe bokwelapha amanzi nge-electrochemical ukubhekana nale nkinga.
Ubuchwepheshe bokwelapha amanzi nge-electrochemical bubhekisela enkambisweni yokuwohloka kokungcola emanzini angcolile ngokusebenzisa ukusabela okuthile kwe-electrochemical, izinqubo ze-electrochemical, noma izinqubo zomzimba ngaphakathi kwe-reactor ethile ye-electrochemical, ngaphansi kwethonya lama-electrode noma insimu kagesi esetshenzisiwe. Izinhlelo nemishini ye-electrochemical ilula kakhulu, ithatha indawo encane, inezindleko zokusebenza eziphansi nezokulungisa, ivimbela ngempumelelo ukungcola kwesibili, inikeza ukulawula okuphezulu kokusabela, futhi ivumela ukuzenzekela kwezimboni, okubenza banikezwe ilebula lobuchwepheshe "obunobungani nemvelo".
Ubuchwepheshe bokwelapha amanzi nge-electrochemical buhlanganisa amasu ahlukahlukene njenge-electrocoagulation-electroflotation, i-electrodialysis, i-electroadsorption, i-electro-Fenton, kanye ne-electrocatalytic advanced oxidation. Lawa masu ayahlukahluka futhi ngalinye linezinhlelo zalo zokusebenza ezifanele kanye nezizinda.
I-Electrocoagulation-I-Electroflotation
Eqinisweni, i-electrocoagulation iwukujikijela kwe-electroflotation, njengoba inqubo yokujikijela yenzeka ngesikhathi esifanayo nokujikijela kwe-fluoro. Ngakho-ke, ingabizwa ngokuthi "i-electrocoagulation-electroflotation".
Le ndlela incike ekusetshenzisweni kwe-voltage kagesi yangaphandle, ekhiqiza ama-cation ancibilikayo ku-anode. La ma-cation anomthelela wokujiya kokungcola kwe-colloidal. Ngesikhathi esifanayo, inani elikhulu legesi ye-hydrogen likhiqizwa ku-cathode ngaphansi kwethonya le-voltage, okusiza izinto ezi-flocculated ukuthi zikhuphukele phezulu. Ngale ndlela, i-electrocoagulation ifinyelela ekuhlukanisweni kokungcola kanye nokuhlanzwa kwamanzi ngokusebenzisa i-anode coagulation kanye ne-cathode flotation.
Kusetshenziswa insimbi njenge-anode encibilikayo (ngokuvamile i-aluminium noma insimbi), ama-ion e-Al3+ noma e-Fe3+ akhiqizwa ngesikhathi se-electrolysis asebenza njengama-coagulant asebenza ngogesi. Lawa ma-coagulant asebenza ngokucindezela ungqimba oluphindwe kabili lwe-colloidal, aluphazamise, futhi avale futhi abambe izinhlayiya ze-colloidal ngokusebenzisa:
Al -3e→ Al3+ noma Fe -3e→ Fe3+
I-Al3+ + 3H2O → Al(OH)3 + 3H+ noma 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-
Ngakolunye uhlangothi, i-electroactive coagulant M(OH)n eyakhiwe ibizwa ngokuthi i-soluble polymeric hydroxo complexes futhi isebenza njenge-flocculant ukuze ijiye ngokushesha nangokuphumelelayo ama-colloidal suspensions (amaconsi kawoyela amancane kanye nokungcola komshini) emanzini angcolile ngenkathi iwahlanganisa futhi iwaxhumanisa ukuze akhe ama-aggregates amakhulu, okusheshisa inqubo yokuhlukanisa. Ngakolunye uhlangothi, ama-colloid acindezelwa ngaphansi kwethonya lama-electrolyte afana nosawoti we-aluminium noma wensimbi, okuholela ekujiyeni ngomphumela we-Coulombic noma ukumuncwa kwama-coagulants.
Nakuba umsebenzi we-electrochemical (isikhathi sokuphila) wama-coagulant asebenza ngogesi ungamaminithi ambalwa nje, athinta kakhulu amandla ongqimba oluphindwe kabili, ngaleyo ndlela asebenzisa imiphumela enamandla yokujiya kwezinhlayiya ze-colloidal noma izinhlayiya ezimisiwe. Ngenxa yalokho, amandla azo okumunca kanye nomsebenzi ziphakeme kakhulu kunezindlela zamakhemikhali ezihilela ukwengezwa kwama-reagents kasawoti we-aluminium, futhi zidinga amanani amancane futhi zinezindleko eziphansi. I-Electrocoagulation ayithintwa yizimo zemvelo, izinga lokushisa lamanzi, noma ukungcola kwezinto eziphilayo, futhi ayihlangabezani nokusabela okungekuhle nosawoti we-aluminium kanye nama-hydroxide amanzi. Ngakho-ke, inobubanzi be-pH obukhulu bokwelapha amanzi angcolile.
Ngaphezu kwalokho, ukukhishwa kwamabhamuza amancane ebusweni be-cathode kusheshisa ukushayisana nokuhlukaniswa kwama-colloids. I-electro-oxidation eqondile ebusweni be-anode kanye ne-electro-oxidation engaqondile ye-Cl- into active chlorine kunamandla amakhulu oku-oxidative ezintweni eziphilayo ezincibilikayo kanye nezinto ezingaphili ezincibilikayo emanzini. I-hydrogen esanda kukhiqizwa evela ku-cathode kanye nomoya-mpilo ovela ku-anode kunamandla amakhulu oku-redox.
Ngenxa yalokho, izinqubo zamakhemikhali ezenzeka ngaphakathi kwe-electrochemical reactor ziyinkimbinkimbi kakhulu. Ku-reactor, izinqubo ze-electrocoagulation, i-electroflotation, kanye ne-electrooxidation zonke zenzeka ngasikhathi sinye, ziguqula futhi zisuse ngempumelelo kokubili ama-colloid ancibilikisiwe kanye nokungcola okulenga emanzini ngokujiya, ukuflotha, kanye ne-oxidation.
