Ehlabathini, yonke into ineenzuzo kunye neengxaki zayo. Inkqubela phambili yoluntu kunye nokuphuculwa komgangatho wokuphila kwabantu ngokuqinisekileyo kukhokelela kungcoliseko lokusingqongileyo. Amanzi amdaka ngomnye umba onjalo. Ngophuhliso olukhawulezayo lwamashishini anje ngepetrochemicals, amalaphu, ukwenza iphepha, izitshabalalisi, amayeza, i-metallurgy, kunye nokuveliswa kokutya, ukukhutshwa okupheleleyo kwamanzi amdaka kuye kwanda kakhulu kwihlabathi liphela. Ngaphezu koko, amanzi amdaka ahlala equlathe ukuxinana okuphezulu, ubutyhefu obuphezulu, ubutyuwa obuphezulu, kunye namalungu aphezulu ombala, okwenza kube nzima ukuthotywa kunye nokunyanga, okukhokelela kungcoliseko olukhulu lwamanzi.
Ukujongana nomthamo omkhulu wamanzi amdaka avela kwimizi-mveliso aveliswa mihla le, abantu baye basebenzisa iindlela ezahlukeneyo, ukudibanisa iindlela zomzimba, iikhemikhali, kunye nebhayoloji, kunye nokusebenzisa amandla anjengombane, isandi, ukukhanya, kunye nemagnethi. Eli nqaku lishwankathela ukusetyenziswa "kombane" kwiteknoloji yokucoca amanzi e-electrochemical ukulungisa lo mba.
Itekhnoloji yokucoca amanzi nge-Electrochemical ibhekisa kwinkqubo yokuthoba ungcoliseko kumanzi amdaka ngokusabela okuthe ngqo kwe-electrochemical, iinkqubo ze-electrochemical, okanye iinkqubo zomzimba ngaphakathi kwereactor ethile ye-electrochemical, phantsi kweempembelelo zee-electrode okanye indawo yombane esetyenziswayo. Iinkqubo ze-Electrochemical kunye nezixhobo zilula, zithatha indawo encinci, zineendleko eziphantsi zokusebenza kunye nokugcinwa, zithintela ngokufanelekileyo ungcoliseko lwesibini, zibonelela ngolawulo oluphezulu lokusabela, kwaye zilungele ukuzenzekelayo kwimizi-mveliso, zibazuzele ileyibhile "yobuchwephesha bendalo".
Itekhnoloji yokucoca amanzi nge-Electrochemical ibandakanya iindlela ezahlukeneyo ezifana ne-electrocoagulation-electroflotation, i-electrodialysis, i-electroadsorption, i-electro-Fenton, kunye ne-electrocatalytic oxidation ephezulu. Ezi ndlela zobuchule zahlukene kwaye nganye inemisebenzi yayo efanelekileyo kunye nemimandla.
Electrocoagulation-Electroflotation
I-Electrocoagulation, eneneni, yi-electroflotation, njengoko inkqubo yokudibanisa iyenzeka ngaxeshanye kunye ne-flotation. Ngoko ke, inokubizwa ngokuba yi "electrocoagulation-electroflotation."
Le ndlela ixhomekeke ekusebenziseni amandla ombane angaphandle, avelisa i-cations e-soluble kwi-anode. Ezi cations zinempembelelo yokudibanisa kwizinto ezingcolisa i-colloidal. Kwangaxeshanye, isixa esikhulu serhasi ye-hydrogen iveliswa kwi-cathode phantsi kwefuthe lombane, onceda izinto ezijikelezileyo zinyukele phezulu. Ngale ndlela, i-electrocoagulation ifezekisa ukwahlulwa kwezinto ezingcolileyo kunye nokucocwa kwamanzi ngokusebenzisa i-anode coagulation kunye ne-cathode flotation.
Ukusebenzisa isinyithi njenge-anode e-soluble (ngokuqhelekileyo i-aluminium okanye isinyithi), i-Al3 + okanye i-Fe3 + ion eyenziwa ngexesha le-electrolysis isebenza njenge-electroactive coagulants. Ezi coagulants zisebenza ngokucinezela umaleko ophindwe kabini we-colloidal, ukuwuphelisa, kunye nokudibanisa kunye nokuthatha amasuntswana e-colloidal ngokusebenzisa:
Al -3e→ Al3+ okanye Fe -3e→ Fe3+
Al3+ + 3H2O → Al(OH)3 + 3H+ okanye 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-
Kwelinye icala, i-electroactive coagulant i-M(OH)n ibizwa ngokuba yi-soluble polymeric hydroxo complexes kwaye isebenza njenge-flocculant ukuze idibanise ngokukhawuleza nangokufanelekileyo i-colloidal suspensions (amathontsi e-oyile afanelekileyo kunye nokungcola komatshini) kumanzi amdaka ngelixa edibanisa kwaye ewadibanisa ukuze enze. ii-aggregates ezinkulu, ukukhawulezisa inkqubo yokwahlula. Ngakolunye uhlangothi, i-colloids ixinzelelwe phantsi kweempembelelo ze-electrolytes ezifana ne-aluminium okanye i-iron salts, ekhokelela ekudibaniseni nge-Coulombic effect okanye i-adsorption ye-coagulants.
Nangona umsebenzi we-electrochemical (ubomi) be-electroactive coagulants yimizuzu embalwa kuphela, ichaphazela kakhulu i-double layer potential, ngaloo ndlela ibeka imiphumo enamandla yokudibanisa kwiincinci ze-colloidal okanye iinqununu ezimisiwe. Ngenxa yoko, umthamo wabo we-adsorption kunye nomsebenzi uphezulu kakhulu kuneendlela zekhemikhali ezibandakanya ukongezwa kwee-reagents zetyuwa ze-aluminium, kwaye zifuna amanani amancinci kwaye zineendleko eziphantsi. I-Electrocoagulation ayichatshazelwa yimeko yokusingqongileyo, ubushushu bamanzi, okanye ukungcola kwebhayoloji, kwaye ayihambi neempendulo zecala kunye neetyuwa ze-aluminium kunye ne-hydroxides yamanzi. Ngoko ke, inoluhlu olubanzi lwe-pH lokunyanga amanzi amdaka.
Ukongeza, ukukhutshwa kwamaqamza amancinci kumphezulu we-cathode kukhawulezisa ukungqubana kunye nokwahlulwa kwe-colloids. I-electro-oxidation ethe ngqo kumphezulu we-anode kunye ne-electro-oxidation engathanga ngqo ye-Cl- ibe yiklorini esebenzayo inamandla oksijini anamandla kwizinto eziphilayo ezinyibilikayo kunye ne-reducible inorganic substances emanzini. I-hydrogen esanda kuveliswa kwi-cathode kunye ne-oksijini esuka kwi-anode inamandla amakhulu okubuyisela kwakhona.
Ngenxa yoko, iinkqubo zeekhemikhali ezenzeka ngaphakathi kwe-electrochemical reactor zintsonkothe kakhulu. Kwi-reactor, i-electrocoagulation, i-electroflotation, kunye ne-electrooxidation iinkqubo zonke zenzeka ngaxeshanye, ziguqula ngokufanelekileyo kwaye zisuse zombini iicolloids ezinyityilisiweyo kunye nongcoliseko olumisiweyo emanzini ngokusebenzisa i-coagulation, i-flotation, kunye ne-oxidation.
