Padziko lapansi, chilichonse chili ndi zabwino zake komanso zoyipa zake. Kupita patsogolo kwa anthu komanso kusintha kwa moyo wa anthu kumabweretsa kuwonongeka kwa chilengedwe. Madzi otayira ndi nkhani imodzi yotere. Ndi chitukuko chofulumira cha mafakitale monga mafuta a petrochemicals, nsalu, kupanga mapepala, mankhwala ophera tizilombo, mankhwala, zitsulo, ndi kupanga zakudya, kutulutsa madzi onyansa kwawonjezeka kwambiri padziko lonse lapansi. Kuphatikiza apo, madzi otayira nthawi zambiri amakhala ndi kuchuluka kwambiri, kawopsedwe wambiri, mchere wambiri, komanso mitundu yambiri yamitundu, zomwe zimapangitsa kuti zikhale zovuta kutsitsa ndikuchiritsa, zomwe zimapangitsa kuti madzi aipitsidwe kwambiri.
Pofuna kuthana ndi kuchuluka kwa madzi otayira m'mafakitale omwe amapangidwa tsiku ndi tsiku, anthu agwiritsa ntchito njira zosiyanasiyana, kuphatikiza njira zakuthupi, zamankhwala, ndi zachilengedwe, komanso kugwiritsa ntchito mphamvu monga magetsi, mawu, kuwala, ndi maginito. Nkhaniyi ikufotokoza mwachidule kagwiritsidwe ntchito ka "magetsi" muukadaulo wamankhwala amadzi a electrochemical kuti athetse vutoli.
Tekinoloje yamagetsi yamagetsi yamagetsi imatanthawuza njira yowonongera zowononga m'madzi oyipa kudzera mumayendedwe apadera a electrochemical, njira zama electrochemical, kapena zochitika zakuthupi mkati mwa chochita china cha electrochemical reactor, mothandizidwa ndi maelekitirodi kapena malo ogwiritsira ntchito magetsi. Machitidwe a Electrochemical ndi zida zake ndizosavuta, zimakhala ndi kagawo kakang'ono, zimakhala ndi ndalama zochepa zogwirira ntchito ndi kukonza, zimateteza bwino kuipitsidwa kwachiwiri, zimapereka kuwongolera kwakukulu kwamachitidwe, komanso zimathandizira kupanga makina opangira mafakitale, zomwe zimawapangitsa kukhala odziwika kuti ndiukadaulo "wokonda chilengedwe".
Ukadaulo wamankhwala amadzi a Electrochemical umaphatikizapo njira zingapo monga electrocoagulation-electroflotation, electrodialysis, electroadsorption, electro-Fenton, ndi electrocatalytic advanced oxidation. Njirazi ndizosiyanasiyana ndipo iliyonse ili ndi magwiritsidwe ake oyenera komanso madera ake.
Electrocoagulation-Electroflotation
Electrocoagulation, kwenikweni, ndi electroflotation, monga momwe coagulation imachitika nthawi imodzi ndi kuyandama. Choncho, akhoza kutchulidwa pamodzi kuti "electrocoagulation-electroflotation."
Njirayi imadalira kugwiritsa ntchito mphamvu yamagetsi yakunja, yomwe imapanga ma cations osungunuka pa anode. Ma cations awa amakhala ndi coagulating pa zoipitsa za colloidal. Panthawi imodzimodziyo, mpweya wochuluka wa haidrojeni umapangidwa pa cathode mothandizidwa ndi voteji, zomwe zimathandiza kuti zinthu zowonongeka zimakwera pamwamba. Mwanjira iyi, electrocoagulation imakwaniritsa kulekanitsa zoipitsa ndi kuyeretsa madzi kudzera mu anode coagulation ndi cathode flotation.
Pogwiritsa ntchito chitsulo monga anode sungunuka (nthawi zambiri aluminium kapena chitsulo), ma ayoni a Al3+ kapena Fe3+ opangidwa panthawi ya electrolysis amakhala ngati ma electroactive coagulants. Ma coagulants awa amagwira ntchito popondereza gawo la colloidal pawiri, ndikulisokoneza, ndikumangirira ndikugwira ma colloidal particles kudzera:
Al -3e→ Al3+ kapena Fe -3e→ Fe3+
Al3+ + 3H2O → Al(OH)3 + 3H+ kapena 4Fe2+ + O2 + 2H2O → 4Fe3+ + 4OH-
Kumbali imodzi, chopangidwa ndi electroactive coagulant M(OH)n imatchedwa sungunuka polymeric hydroxo complexes ndipo imagwira ntchito ngati flocculant kuti isungunuke mwachangu komanso moyenera kuyimitsidwa kwa colloidal (madontho abwino amafuta ndi zodetsa zamakina) m'madzi otayidwa ndikumangirira ndikuwalumikiza kuti apange. magulu akuluakulu, kufulumizitsa njira yolekanitsa. Kumbali inayi, ma colloids amapanikizidwa ndi ma electrolyte monga aluminiyamu kapena mchere wachitsulo, zomwe zimatsogolera ku coagulation kudzera mu Coulombic effect kapena ma adsorption a coagulants.
Ngakhale electrochemical ntchito (moyo) wa electroactive coagulants ndi mphindi zochepa chabe, iwo kwambiri zimakhudza iwiri wosanjikiza angathe, motero ndi amphamvu coagulation zotsatira pa colloidal particles kapena inaimitsidwa particles. Chotsatira chake, mphamvu zawo zowonongeka ndi ntchito ndizokwera kwambiri kuposa njira zamakina zomwe zimaphatikizapo kuwonjezera ma reagents amchere a aluminiyamu, ndipo zimafuna ndalama zochepa komanso zimakhala ndi ndalama zochepa. Electrocoagulation sichimakhudzidwa ndi chilengedwe, kutentha kwa madzi, kapena zonyansa zamoyo, ndipo sichimakhudzidwa ndi mchere wa aluminiyamu ndi ma hydroxides amadzi. Chifukwa chake, ili ndi mitundu yambiri ya pH yochizira madzi oyipa.
Kuonjezera apo, kutulutsidwa kwa tinthu ting'onoting'ono pamtunda wa cathode kumafulumizitsa kugunda ndi kulekanitsa kwa colloids. The electro-oxidation mwachindunji pa anode pamwamba ndi indirect electro-oxidation wa Cl- mu yogwira klorini ali ndi mphamvu okosijeni pa sungunuka organic zinthu ndi reducible inorganic zinthu m'madzi. Ma hydrogen opangidwa kumene kuchokera ku cathode ndi okosijeni kuchokera ku anode ali ndi mphamvu zamphamvu za redox.
Zotsatira zake, njira zamakina zomwe zimachitika mkati mwa electrochemical reactor ndizovuta kwambiri. Mu riyakitala, electrocoagulation, electroflotation, ndi electrooxidation njira zonse zimachitika nthawi imodzi, kusintha bwino ndikuchotsa ma colloid osungunuka ndi zoyipitsidwa zoyimitsidwa m'madzi kudzera mu coagulation, kuyandama, ndi okosijeni.
