Padziko lonse lapansi, chilichonse chili ndi zabwino ndi zoyipa zake. Kupita patsogolo kwa anthu komanso kusintha kwa miyoyo ya anthu kumabweretsa kuipitsidwa kwa chilengedwe. Madzi otayidwa ndi vuto limodzi lotere. Chifukwa cha kupita patsogolo mwachangu kwa mafakitale monga mafuta, nsalu, kupanga mapepala, mankhwala ophera tizilombo, mankhwala, zitsulo, ndi kupanga chakudya, kutulutsa madzi otayidwa konse kwawonjezeka kwambiri padziko lonse lapansi. Kuphatikiza apo, madzi otayidwa nthawi zambiri amakhala ndi kuchuluka kwakukulu, poizoni wambiri, mchere wambiri, ndi zinthu zamitundu yambiri, zomwe zimapangitsa kuti zikhale zovuta kuwononga ndi kukonza, zomwe zimapangitsa kuti madzi aipitsidwe kwambiri.
Pofuna kuthana ndi madzi ambiri otayira omwe amapangidwa tsiku ndi tsiku, anthu agwiritsa ntchito njira zosiyanasiyana, kuphatikiza njira zakuthupi, zamankhwala, ndi zamoyo, komanso kugwiritsa ntchito mphamvu monga magetsi, phokoso, kuwala, ndi maginito. Nkhaniyi ikufotokoza mwachidule kugwiritsa ntchito "magetsi" muukadaulo wamagetsi wochizira madzi kuti athetse vutoli.
Ukadaulo wokonza madzi pogwiritsa ntchito electrochemical umatanthauza njira yowononga zinthu zonyansa m'madzi otayira kudzera mu machitidwe enaake a electrochemical, njira zamagetsi, kapena machitidwe enieni mkati mwa reactor inayake ya electrochemical, motsogozedwa ndi ma electrode kapena gawo lamagetsi lomwe lagwiritsidwa ntchito. Makina ndi zida zamagetsi ndi zosavuta, zimakhala ndi malo ochepa, zimakhala ndi ndalama zochepa zogwirira ntchito ndi kukonza, zimaletsa kuipitsa kwachiwiri, zimapereka kuthekera kwakukulu kowongolera zochitika, ndipo zimathandiza kuti mafakitale azigwira ntchito, zomwe zimawapangitsa kukhala ukadaulo "woteteza chilengedwe".
Ukadaulo wokonza madzi pogwiritsa ntchito electrochemical umaphatikizapo njira zosiyanasiyana monga electrocoagulation-electroflotation, electrodialysis, electroadsorption, electro-Fenton, ndi electrocatalytic advanced oxidation. Njirazi ndi zosiyanasiyana ndipo iliyonse ili ndi ntchito zake zoyenera komanso madera ake.
Kuchuluka kwa magazi m'thupi (Electrocoagulation)
Electrocoagulation, kwenikweni, ndi electroflotation, chifukwa njira yolumikizirana imachitika nthawi imodzi ndi flotation. Chifukwa chake, imatha kutchedwa "electrocoagulation-electroflotation."
Njira imeneyi imadalira kugwiritsa ntchito magetsi akunja, omwe amapanga ma cations osungunuka pa anode. Ma cations awa amakhala ndi mphamvu yozungulira pa zonyansa za colloidal. Nthawi yomweyo, mpweya wambiri wa haidrojeni umapangidwa pa cathode motsogozedwa ndi magetsi, zomwe zimathandiza kuti zinthu zophwanyika zikwere pamwamba. Mwanjira imeneyi, magetsi ozungulira amathetsa kulekanitsa zonyansa ndi kuyeretsa madzi kudzera mu anode coagulation ndi cathode flotation.
Pogwiritsa ntchito chitsulo ngati anode yosungunuka (nthawi zambiri aluminiyamu kapena chitsulo), ma ayoni a Al3+ kapena Fe3+ omwe amapangidwa panthawi ya electrolysis amagwira ntchito ngati ma coagulant amagetsi. Ma coagulant awa amagwira ntchito pofinya colloidal double layer, kuisokoneza, ndikulumikiza ndikugwira tinthu ta colloidal kudzera:
Al -3e→ Al3+ kapena Fe -3e→ Fe3+
Al3+ + 3H2O → Al(OH)3 + 3H+ kapena 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-
Kumbali imodzi, coagulant yopangidwa ndi electroactive M(OH)n imatchedwa soluble polymeric hydroxo complexes ndipo imagwira ntchito ngati flocculant yothira mwachangu komanso moyenera ma colloidal suspensions (madontho amafuta abwino ndi zonyansa zamakina) m'madzi otayira pamene ikuwalumikiza ndikupanga magulu akuluakulu, zomwe zimapangitsa kuti njira yolekanitsa ifulumizitse. Kumbali ina, ma colloid amakanikizidwa pogwiritsa ntchito ma electrolyte monga aluminiyamu kapena mchere wachitsulo, zomwe zimapangitsa kuti coagulant igwidwe kudzera mu Coulombic effect kapena kulowetsedwa kwa coagulants.
Ngakhale kuti mphamvu ya ma electrochemical (nthawi ya moyo) ya ma coagulants ogwiritsira ntchito magetsi ndi mphindi zochepa chabe, amakhudza kwambiri mphamvu ya ma double layer, motero amakhala ndi mphamvu yolimba yolumikizirana pa tinthu ta colloidal kapena tinthu tomwe timayimitsidwa. Zotsatira zake, mphamvu yawo yolowetsa ndi ntchito zake zimakhala zapamwamba kwambiri kuposa njira zamakemikolo zomwe zimaphatikizapo kuwonjezera ma reagents a mchere wa aluminiyamu, ndipo zimafuna zochepa ndipo zimakhala ndi ndalama zochepa. Kulumikizana kwa magetsi sikukhudzidwa ndi nyengo, kutentha kwa madzi, kapena zonyansa zamoyo, ndipo sikukumana ndi zotsatira zoyipa ndi mchere wa aluminiyamu ndi madzi hydroxides. Chifukwa chake, ili ndi pH yochuluka yochizira madzi otayidwa.
Kuphatikiza apo, kutulutsidwa kwa thovu laling'ono pamwamba pa cathode kumafulumizitsa kugundana ndi kulekanitsidwa kwa ma colloids. Kuchuluka kwa ma electro-oxidation mwachindunji pamwamba pa anode ndi kuchuluka kwa ma electro-oxidation osalunjika a Cl- into active chlorine kumakhala ndi mphamvu yamphamvu ya okosijeni pa zinthu zachilengedwe zosungunuka ndi zinthu zosapangidwa m'madzi. Hydrogen yatsopano yopangidwa kuchokera ku cathode ndi mpweya wochokera ku anode ili ndi mphamvu yamphamvu ya redox.
Zotsatira zake, njira za mankhwala zomwe zimachitika mkati mwa electrochemical reactor zimakhala zovuta kwambiri. Mu electroreactor, njira za electrocoagulation, electroflotation, ndi electrooxidation zimachitika nthawi imodzi, zomwe zimasintha bwino ndikuchotsa ma colloids osungunuka ndi zonyansa zomwe zimayimitsidwa m'madzi kudzera mu coagulation, flotation, ndi oxidation.
