Emhlabeni, yonke into inobuhle bayo nobubi bayo. Inqubekelaphambili yomphakathi kanye nokwenza ngcono izinga lokuphila kwabantu kuholela ekungcolisweni kwemvelo. Amanzi angcolile angenye yezinkinga ezinjalo. Ngokuthuthuka okusheshayo kwezimboni ezifana namakhemikhali e-petrochemicals, izindwangu, ukwenza amaphepha, izibulala-zinambuzane, imithi, i-metallurgy, kanye nokukhiqizwa kokudla, ukuchithwa okuphelele kwamanzi angcolile kuye kwanda kakhulu emhlabeni jikelele. Ngaphezu kwalokho, amanzi angcolile ngokuvamile aqukethe ukugxila okuphezulu, ubuthi obuphezulu, usawoti omningi, kanye nezingxenye ezinemibala ephezulu, okwenza kube nzima ukwehlisa nokwelapha, okuholela ekungcoleni kwamanzi okukhulu.
Ukuze babhekane nomthamo omkhulu wamanzi angcolile ezimbonini akhiqizwa nsuku zonke, abantu baye basebenzisa izindlela ezihlukahlukene, ezihlanganisa izindlela ezingokomzimba, zamakhemikhali, nezebhayoloji, kanye nokusebenzisa amandla anjengogesi, umsindo, ukukhanya, namandla kazibuthe. Lesi sihloko sifingqa ukusetshenziswa "kogesi" kubuchwepheshe bokwelashwa kwamanzi we-electrochemical ukubhekana nalolu daba.
Ubuchwepheshe bokuhlanza amanzi nge-electrochemical busho inqubo yokwehlisa isithunzi esingcolisayo emanzini angcolile ngokusabela okuthile kwe-electrochemical, izinqubo ze-electrochemical, noma izinqubo zomzimba ngaphakathi kwereactor ethile ye-electrochemical, ngaphansi kwethonya lama-electrode noma insimu kagesi esetshenziswayo. Amasistimu namathuluzi e-electrochemical alula uma kuqhathaniswa, athatha indawo encane, anezindleko eziphansi zokusebenza nezokulungisa, avimbela ngempumelelo ukungcoliswa kwesibili, anikezela ngokulawuleka okuphezulu kokusabela, futhi ahambisana ne-automation yezimboni, azitholele ilebula yobuchwepheshe "bobungani bemvelo".
Ubuchwepheshe bokwelapha amanzi nge-Electrochemical buhlanganisa amasu ahlukahlukene afana ne-electrocoagulation-electroflotation, i-electrodialysis, i-electroadsorption, i-electro-Fenton, ne-electrocatalytic advanced oxidation. Lawa masu ahlukene futhi ngalinye linezinhlelo zalo ezifanele nezizinda.
I-Electrocoagulation-Electroflotation
I-Electrocoagulation, empeleni, i-electroflotation, njengoba inqubo yokuhlangana kwenzeka kanyekanye nokuntanta. Ngakho-ke, ingabizwa ngokuhlanganyela ngokuthi "electrocoagulation-electroflotation."
Le ndlela incike ekusetshenzisweni kwe-voltage yangaphandle kagesi, ekhiqiza ama-cations ancibilikayo ku-anode. Lawa ma-cations anomthelela wokuhlangana ezintweni ezingcolisa i-colloidal. Ngesikhathi esifanayo, inani elikhulu legesi le-hydrogen likhiqizwa ku-cathode ngaphansi kwethonya likagesi, elisiza i-flocculated material ikhuphuke phezulu. Ngale ndlela, i-electrocoagulation ifinyelela ukuhlukaniswa kokungcola kanye nokuhlanzwa kwamanzi ngokusebenzisa i-anode coagulation kanye ne-cathode flotation.
Kusetshenziswa insimbi njenge-anode encibilikayo (imvamisa i-aluminium noma insimbi), ama-ion e-Al3+ noma i-Fe3+ akhiqizwa phakathi ne-electrolysis asebenza njengama-coagulant kagesi. Lawa ma-coagulant asebenza ngokucindezela ungqimba oluphindwe kabili lwe-colloidal, aluphazamise, futhi alubhule 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 engu-M(OH)n ebizwa ngokuthi i-soluble polymeric hydroxo complexes futhi isebenza njenge-flocculant ukuze ihlanganise ngokushesha nangempumelelo ukumiswa kwe-colloidal (amaconsi kawoyela amahle kanye nokungcola kwemishini) emanzini angcolile ngenkathi ehlanganisa futhi ewaxhuma ukuze akhe. ama-aggregate amakhulu, asheshisa inqubo yokuhlukanisa. Ngakolunye uhlangothi, ama-colloid acindezelwa ngaphansi kwethonya lama-electrolyte afana ne-aluminium noma usawoti wensimbi, okuholela ekuhlanganiseni ngomphumela we-Coulombic noma i-adsorption yama-coagulants.
Nakuba umsebenzi we-electrochemical (isikhathi sokuphila) wama-coagulants e-electroactive kuyimizuzu embalwa kuphela, athinta ngokuphawulekayo amandla ongqimba oluphindwe kabili, ngaleyo ndlela abe nemiphumela eqinile yokuhlangana ezinhlayiyeni ze-colloidal noma izinhlayiya ezimisiwe. Ngenxa yalokho, amandla abo okukhangisa kanye nomsebenzi kuphakeme kakhulu kunezindlela zamakhemikhali ezihlanganisa ukufakwa kwe-aluminium reagents kasawoti, futhi zidinga amanani amancane futhi zinezindleko eziphansi. I-Electrocoagulation ayithintwa izimo zemvelo, izinga lokushisa kwamanzi, noma ukungcola kwebhayoloji, futhi ayihlanganyeli nosawoti we-aluminium nama-hydroxides amanzi. Ngakho-ke, inohlu olubanzi lwe-pH lokwelapha amanzi angcolile.
Ukwengeza, ukukhishwa kwamabhamuza amancane endaweni ye-cathode kusheshisa ukungqubuzana nokuhlukaniswa kwama-colloid. I-electro-oxidation eqondile endaweni ye-anode kanye ne-electro-oxidation engaqondile ye-Cl- into ye-chlorine esebenzayo inamandla aqinile oksijini ezintweni eziphilayo ezincibilikayo nezinto ezingaphili ezincibilikayo emanzini. I-hydrogen esanda kukhiqizwa evela ku-cathode nomoya-mpilo ovela ku-anode inamakhono aqinile we-redox.
Ngenxa yalokho, izinqubo zamakhemikhali ezenzeka ngaphakathi kwe-electrochemical reactor ziyinkimbinkimbi kakhulu. Ku-reactor, i-electrocoagulation, i-electroflotation, kanye nezinqubo ze-electrooxidation zonke zenzeka ngesikhathi esisodwa, ziguqule ngempumelelo futhi zisuse womabili ama-colloid ancibilikile kanye nokungcola okumisiwe emanzini ngokuhlangana, ukuntanta, kanye ne-oxidation.
