Ku isi, ibintu byose bifite ibyiza n'ibibi byabyo. Iterambere ry'umuryango n'iterambere ry'imibereho y'abantu nta kabuza bitera kwanduza ibidukikije. Amazi yanduye ni kimwe mu bibazo nk'ibyo. Bitewe n'iterambere ryihuse ry'inganda nka peteroli, imyenda, impapuro, imiti yica udukoko, imiti, ibyuma, n'umusaruro w'ibiribwa, amazi yanduye yose yariyongereye cyane ku isi yose. Byongeye kandi, amazi yanduye akunze kuba afite uburozi bwinshi, uburozi bwinshi, umunyu mwinshi, n'ibice by'amabara menshi, bigatuma bigorana kuyangiza no kuyatunganya, bigatuma amazi yandura cyane.
Kugira ngo abantu bashobore guhangana n’amazi menshi yanduye akorwa buri munsi mu nganda, bakoresheje uburyo butandukanye, bahuza uburyo bufatika, ubutabire n’ubw’ibinyabuzima, ndetse banakoresha imbaraga nk’amashanyarazi, amajwi, urumuri, na rukuruzi. Iyi nkuru ivuga muri make ikoreshwa ry’ “amashanyarazi” mu ikoranabuhanga ryo gutunganya amazi hakoreshejwe amashanyarazi kugira ngo iki kibazo gikemuke.
Ikoranabuhanga ryo gutunganya amazi hakoreshejwe amashanyarazi risobanura inzira yo kwangiza imyanda mu mazi yanduye binyuze mu buryo bwihariye bwo gukora amashanyarazi, imikorere ya electrochemical, cyangwa ibikorwa bifatika mu cyuma runaka cy’amashanyarazi, hakoreshejwe amashanyarazi cyangwa amashanyarazi akoreshwa. Sisitemu n'ibikoresho bya electrochemical biroroshye, bifite igice gito cy'ingenzi, bifite ikiguzi gito cyo gukora no kubungabunga, birinda umwanda wa kabiri, bitanga ubushobozi bwo kugenzura imikorere, kandi bifasha mu gukora ikoranabuhanga mu nganda, bigatuma bihabwa izina ry'ikoranabuhanga "rirengera ibidukikije".
Ikoranabuhanga ryo gutunganya amazi hakoreshejwe amashanyarazi rikubiyemo uburyo butandukanye nka electrocoagulation-electroflotation, electrodialysis, electroadsorption, electro-Fenton, na electrocatalytic advanced oxidation. Ubu buryo buratandukanye kandi buri bumwe bufite uburyo bwabwo n'imiterere yabwo.
Electrocoagulation-Electroflotation
Mu by’ukuri, Electrocoagulation ni electroflotation, kuko inzira yo gufungana iba rimwe na flotation. Kubwibyo, ishobora kwitwa "electrocoagulation-electroflotation."
Ubu buryo bushingiye ku ikoreshwa ry'amashanyarazi yo hanze, atuma habaho amashanyarazi ashongeshwa kuri anode. Izi mashini zigira ingaruka zo gufungana ku myanda ya colloidal. Muri icyo gihe, ingano nini ya gazi ya hydrogen ikorerwa kuri cathode ikoreshejwe na voltage, igafasha ibintu bisohoka kuzamuka hejuru. Muri ubu buryo, electrocoagulation igera ku gutandukanya imyanda no gusukura amazi binyuze mu gufungana kwa anode na cathode flotation.
Hakoreshejwe icyuma nk'umusemburo w'aside (ubusanzwe ni aluminiyumu cyangwa icyuma), iyoni za Al3+ cyangwa Fe3+ zikorwa mu gihe cy'amashanyarazi zikora nk'imiyoboro y'amashanyarazi. Izi miyoboro ikora mu gukanda urwego rw'inyuma rw'inyuma rw'inyuma, ikaruhungabanya, kandi igahuza kandi igafata uduce twa colloidal muri:
Al -3e → Al3 + cyangwa Fe -3e → Fe3 +
Al3 + + 3H2O → Al (OH) 3 + 3H + cyangwa 4Fe2 + + O2 + 2H2O → 4Fe3 + + 4OH-
Ku ruhande rumwe, coagulant M(OH)n yakozwe yitwa polymeric hydroxo complexes isobeka kandi ikora nk'ikinyabutabire cyo gufunga vuba kandi neza ibintu bifunganye bya colloidal (ibitonyanga by'amavuta n'imyanda ya mekanike) mu mazi yanduye mu gihe ihuza kandi ikabihuza kugira ngo bikore aggregates nini, bikihutisha inzira yo gutandukana. Ku rundi ruhande, colloides zishyirwa hasi bitewe n'ibinyabutabire nka aluminiyumu cyangwa umunyu w'icyuma, bigatuma coagulant ifungana binyuze mu ngaruka za Coulombic cyangwa inyunganira ya coagulants.
Nubwo imikorere y’amashanyarazi (igihe cy’ubuzima) ya coagulants zikora ku buryo bw’amashanyarazi ari iminota mike gusa, zigira ingaruka zikomeye ku bushobozi bwo gufungana kw’ibice bibiri, bityo bigira ingaruka zikomeye ku tuntu twa colloidal cyangwa uduce duhagaze. Kubera iyo mpamvu, ubushobozi bwabyo bwo kuvoma n’imikorere yabyo biri hejuru cyane kurusha uburyo bwa shimi burimo kongeramo umunyu wa aluminiyumu, kandi bisaba ingano nto kandi bifite ikiguzi gito. Electrocoagulant ntabwo iterwa n’imiterere y’ibidukikije, ubushyuhe bw’amazi, cyangwa imyanda y’ibinyabuzima, kandi ntigira ingaruka mbi ku myunyu ya aluminiyumu na hydroxide y’amazi. Kubwibyo, ifite pH nyinshi yo gutunganya amazi yanduye.
Byongeye kandi, kurekura uduce duto tw’utubyimba ku buso bwa cathode byihutisha gukubitana no gutandukana kwa colloids. Electro-oxidation itaziguye ku buso bwa anode hamwe na electro-oxidation itaziguye ya Cl- muri chlorine active bifite ubushobozi bukomeye bwa oxidation ku bintu bishongesha mu binyabuzima ndetse n’ibintu bidashobora kugabanuka mu mazi. Hydrogen nshya iva muri cathode na ogisijeni iva muri anode bifite ubushobozi bukomeye bwo kugarura oxidation.
Kubera iyo mpamvu, inzira za shimi zibera muri reactor ya electrochemical ziragoye cyane. Muri reactor, inzira za electrocoagulation, electroflotation, na electrooxidation byose bibaho icyarimwe, bigahindura kandi bigakuraho neza colloids zashongeshejwe n'imyanda iva mu mazi binyuze mu gufungana, gufungana, no gufungana.
