Mw'isi, ibintu byose bifite ibyiza n'ibibi. Iterambere rya societe no kuzamura imibereho yabaturage byanze bikunze bitera umwanda ibidukikije. Amazi mabi ni kimwe mubibazo nkibi. Iterambere ryihuse ry’inganda nka peteroli, imiti, imyenda, gukora imiti yica udukoko, imiti yica imiti, metallurgie, n’umusaruro w’ibiribwa, isohoka ry’amazi mabi yiyongereye ku isi hose. Byongeye kandi, amazi mabi akunze kuba afite ubukana bwinshi, uburozi bwinshi, umunyu mwinshi, hamwe nibice byinshi byamabara, bigatuma bigorana gutesha agaciro no kuvura, bigatuma umwanda ukabije.
Kugira ngo bahangane n’amazi menshi y’amazi y’inganda akorwa buri munsi, abantu bakoresheje uburyo butandukanye, bahuza uburyo bw’umubiri, imiti, n’ibinyabuzima, ndetse no gukoresha imbaraga nk’amashanyarazi, amajwi, urumuri, na magnetisme. Iyi ngingo ivuga muri make ikoreshwa rya "amashanyarazi" mu ikoranabuhanga ryo gutunganya amazi y’amashanyarazi kugira ngo iki kibazo gikemuke.
Ikoranabuhanga mu gutunganya amazi y’amashanyarazi bivuga inzira yo kwangiza imyanda ihumanya amazi y’amazi binyuze mu buryo bwihariye bw’amashanyarazi, inzira y’amashanyarazi, cyangwa inzira zifatika mu mashanyarazi runaka, bitewe na electrode cyangwa umurima w’amashanyarazi ukoreshwa. Sisitemu ya mashanyarazi n'ibikoresho biroroshye cyane, bifite ikirenge gito, bifite amafaranga make yo gukora no kubungabunga, birinda neza umwanda wa kabiri, bitanga uburyo bwo guhangana n’ibisubizo, kandi bifasha mu gutangiza inganda, bikababera ikirango cy’ikoranabuhanga "ryangiza ibidukikije".
Ikoranabuhanga mu gutunganya amazi y’amashanyarazi ririmo tekiniki zitandukanye nka electrocoagulation-electroflotation, electrodialysis, electroadsorption, electro-Fenton, na okiside ya electrocatalytic. Ubu buhanga buratandukanye kandi buriwese afite porogaramu zikwiye hamwe na domaine.
Amashanyarazi-Amashanyarazi
Electrocoagulation, mubyukuri, ni electroflotation, kuko inzira ya coagulation ibaho hamwe na flotation. Kubwibyo, irashobora kwitwa hamwe "electrocoagulation-electroflotation."
Ubu buryo bushingira kumikoreshereze yumuriro wamashanyarazi wo hanze, utanga ibisubizo byoroshye kuri anode. Iyi cations igira ingaruka zifatika kumyanda ihumanya. Icyarimwe, ubwinshi bwa gaze ya hydrogène ikorerwa kuri cathode iyobowe na voltage, ifasha ibintu bya flokulike kuzamuka hejuru. Muri ubu buryo, electrocoagulation igera ku gutandukanya umwanda no kweza amazi binyuze muri anode coagulation hamwe na cathode flotation.
Ukoresheje icyuma nka anode ishonga (mubisanzwe aluminium cyangwa fer), ion ya Al3 + cyangwa Fe3 + yakozwe mugihe cya electrolysis ikora nka coagulants ya electroactive. Izi coagulants zikora muguhuza ibice bibiri bya colloidal, kubihagarika, no kubiraro no gufata uduce duto twa colloidal binyuze:
Al -3e → Al3 + cyangwa Fe -3e → Fe3 +
Al3 + + 3H2O → Al (OH) 3 + 3H + cyangwa 4Fe2 + + O2 + 2H2O → 4Fe3 + + 4OH-
Ku ruhande rumwe, coagulant yakozwe na electroactive coagulant M (OH) n ivugwa nka polymeric hydroxo soluble soluble kandi ikora nka flocculant kugirango ihuze vuba kandi neza ihagarikwa rya colloidal (ibitonyanga byamavuta meza hamwe nubumara bwa mashini) mumazi mabi mugihe ikiraro no kubahuza kugirango bibeho binini byinshi, byihutisha inzira yo gutandukana. Ku rundi ruhande, colloide iranyeganyezwa bitewe na electrolytite nka aluminium cyangwa umunyu w'icyuma, biganisha kuri coagulation binyuze mu ngaruka za Coulombic cyangwa adsorption ya coagulants.
Nubwo ibikorwa byamashanyarazi (igihe cyigihe) cya coagulants yamashanyarazi ari iminota mike gusa, bigira ingaruka zikomeye kubishobora kuba byikubye kabiri, bityo bikagira ingaruka zikomeye ziterwa no guhuza ibice cyangwa ibice byahagaritswe. Nkigisubizo, ubushobozi bwa adsorption nibikorwa birarenze cyane uburyo bwa chimique burimo kongeramo reagent yumunyu wa aluminium, kandi bisaba amafaranga make kandi bifite igiciro gito. Amashanyarazi ntagerwaho n’ibidukikije, ubushyuhe bw’amazi, cyangwa umwanda w’ibinyabuzima, kandi ntabwo bigira ingaruka ku myunyu ya aluminium na hydroxide y’amazi. Kubwibyo, ifite pH nini mugutunganya amazi mabi.
Byongeye kandi, kurekura utubuto duto hejuru ya cathode byihutisha kugongana no gutandukanya colloide. Electro-okiside itaziguye hejuru ya anode hamwe na electro-okiside itaziguye ya Cl- muri chlorine ikora ifite imbaraga zikomeye za okiside ku bintu kama kama kandi bigabanuka mu mazi. Hydrogen nshya yakozwe muri cathode na ogisijeni ivuye muri anode ifite ubushobozi bukomeye bwa redox.
Nkigisubizo, inzira yimiti ibera mumashanyarazi ya electrochemic iragoye cyane. Muri reaktor, electrocoagulation, electroflotation, hamwe na electrooxidation byose bibaho icyarimwe, bihindura neza kandi bigakuraho colloide yashonze hamwe n’imyanda ihumanya mumazi binyuze muri coagulation, flotation, na okiside.
