Electrocoagulation (EC) ndi njira yomwe imagwiritsa ntchito mphamvu zamagetsi kuchotsa zinthu zodetsa m'madzi otayidwa. Imagwiritsa ntchito mphamvu yamagetsi ya DC kusungunula ma electrode otayidwa, omwe kenako amatulutsa ma ayoni achitsulo omwe amathira ndi zinthu zoipitsa. Njirayi yatchuka chifukwa cha kugwira ntchito kwake bwino, kusamala chilengedwe, komanso kusinthasintha kwake pochiza mitundu yosiyanasiyana ya madzi otayidwa.
Mfundo Zokhudza Kugawanika kwa Ma Electrocoagulation
Mu electrocoagulation, mphamvu yamagetsi imadutsa kudzera mu ma electrode achitsulo omwe amamizidwa m'madzi otayira. Anode (electrode yabwino) imasungunuka, ndikutulutsa ma cation achitsulo monga aluminiyamu kapena chitsulo m'madzi. Ma ion achitsulo awa amachitapo kanthu ndi zonyansa zomwe zili m'madzi, ndikupanga ma hydroxide osasungunuka omwe amasonkhana ndipo amatha kuchotsedwa mosavuta. Cathode (electrode yoyipa) imapanga mpweya wa haidrojeni, womwe umathandiza kuyandamitsa tinthu tomwe timathiridwa pamwamba kuti tichotse madzi.
Njira yonseyi ingathe kufotokozedwa mwachidule m'magawo otsatirawa:
Electrolysis: magetsi a DC amagwiritsidwa ntchito pa ma electrode, zomwe zimapangitsa kuti anode isungunuke ndikutulutsa ma ayoni achitsulo.
Kugawanika: Ma ayoni achitsulo otulutsidwa amaletsa mphamvu za tinthu tomwe timapachikidwa ndi zinthu zodetsa zomwe zimasungunuka, zomwe zimapangitsa kuti pakhale magulu akuluakulu a zinthu.
Kuyandama: Mabowo a mpweya wa haidrojeni omwe amapangidwa pa cathode omwe amalumikizana ndi ma aggregates, zomwe zimapangitsa kuti ayandame pamwamba.
Kulekanitsa: Dothi loyandama limachotsedwa pochotsa madzi m'nthaka, pomwe matope okhazikika amasonkhanitsidwa kuchokera pansi.
Ubwino wa DC Power Supply mu Electrocoagulation
Kuchita bwino: magetsi a DC amalola kuwongolera molondola mphamvu yamagetsi ndi magetsi omwe amagwiritsidwa ntchito, kukonza bwino kusungunuka kwa ma electrode ndikuwonetsetsa kuti zinthu zodetsa zimagwira bwino ntchito.
Kusavuta: Kukhazikitsa kwa electrocoagulation pogwiritsa ntchito DC power supply ndikosavuta, komwe kumakhala ndi magetsi, ma electrode, ndi chipinda chochitirapo kanthu.
Ubwino Wachilengedwe: Mosiyana ndi kukhuthala kwa mankhwala, kukhuthala kwa magetsi sikufuna kuwonjezera mankhwala akunja, zomwe zimachepetsa chiopsezo cha kuipitsidwa kwachiwiri.
Kusinthasintha: EC imatha kuchiza zinthu zosiyanasiyana zoipitsa, kuphatikizapo zitsulo zolemera, mankhwala achilengedwe, zinthu zolimba zomwe zimapachikidwa, komanso tizilombo toyambitsa matenda.
Kugwiritsa Ntchito Electrocoagulation mu Chithandizo cha Madzi Otayidwa
Madzi Otayidwa a Mafakitale: Kuthira madzi m'madzi pogwiritsa ntchito electrocoagulation kumathandiza kwambiri pochiza madzi otayidwa a mafakitale okhala ndi zitsulo zolemera, utoto, mafuta, ndi zinthu zina zoipitsa. Makampani monga nsalu, electroplating, ndi mankhwala amapindula ndi mphamvu ya EC yochotsa zinthu zoopsa ndikuchepetsa kufunika kwa mpweya wa okosijeni (COD).
Madzi Otayidwa a Municipal: EC ingagwiritsidwe ntchito ngati njira yoyamba kapena yachiwiri yochizira madzi otayidwa a municipal, kuthandiza kuchotsa zinthu zolimba zomwe zapachikidwa, ma phosphate, ndi tizilombo toyambitsa matenda. Imawonjezera ubwino wonse wa madzi otayidwa, zomwe zimapangitsa kuti akhale oyenera kutayidwa kapena kugwiritsidwanso ntchito.
Kuthamanga kwa Madzi mu Ulimi: EC imatha kuchiza madzi otuluka mu ulimi omwe ali ndi mankhwala ophera tizilombo, feteleza, ndi zinthu zachilengedwe. Kugwiritsa ntchito kumeneku kumathandiza kuchepetsa zotsatira za ntchito zaulimi pamadzi apafupi.
Chithandizo cha Madzi a Mphepo: EC ingagwiritsidwe ntchito pochotsa zinyalala, zitsulo zolemera, ndi zinthu zina zoipitsa madzi, zomwe zingalepheretse kulowa m'madzi achilengedwe.
Magawo Ogwira Ntchito ndi Kukhathamiritsa
Kugwira ntchito kwa electrocoagulation kumadalira magawo angapo ogwirira ntchito, kuphatikizapo:
Kuchuluka kwa Mphamvu: Kuchuluka kwa mphamvu yomwe imagwiritsidwa ntchito pa gawo lililonse la elekitirodi kumakhudza kuchuluka kwa kutulutsidwa kwa ayoni yachitsulo komanso kugwira ntchito bwino kwa njira yonse. Kuchuluka kwa mphamvu yamagetsi kumatha kuwonjezera mphamvu ya chithandizo koma kungayambitsenso kugwiritsa ntchito mphamvu zambiri komanso kuwonongeka kwa elekitirodi.
Zipangizo za Electrode: Kusankha kwa zipangizo za electrode (kawirikawiri aluminiyamu kapena chitsulo) kumakhudza mtundu ndi magwiridwe antchito a coagulation. Zipangizo zosiyanasiyana zimasankhidwa kutengera zodetsa zomwe zili m'madzi otayidwa.
pH: pH ya madzi otayidwa imakhudza kusungunuka ndi kupangika kwa zitsulo zosungunuka. Kuchuluka kwa pH koyenera kumatsimikizira kuti ma coagulation amagwira ntchito bwino kwambiri komanso kuti ma aggregates opangidwawo azikhala olimba.
Kapangidwe ka Ma Electrode: Kakonzedwe ndi mtunda wa ma electrode zimakhudza kufalikira kwa magetsi komanso kufanana kwa njira yochizira. Kapangidwe koyenera kamawonjezera kukhudzana pakati pa ma ayoni achitsulo ndi zinthu zodetsa.
Nthawi Yochitira Zinthu: Kutalika kwa nthawi yochita zinthu pogwiritsa ntchito magetsi kumakhudza kuchuluka kwa zinthu zodetsa. Nthawi yokwanira yochitira zinthu imatsimikizira kuti zinthu zodetsa zimaundana komanso kulekanitsidwa kwa zinthu zodetsa.
Mavuto ndi Malangizo Amtsogolo
Ngakhale ubwino wake, electrocoagulation ikukumana ndi mavuto ena:
Kugwiritsa Ntchito Ma Electrode: Kudzipereka kwa anode kumapangitsa kuti igwiritsidwe ntchito pang'onopang'ono, zomwe zimafuna kusinthidwa nthawi ndi nthawi kapena kubwezeretsedwanso.
Kugwiritsa Ntchito Mphamvu: Ngakhale kuti magetsi a DC amalola kulamulira molondola, amatha kugwiritsa ntchito mphamvu zambiri, makamaka pa ntchito zazikulu.
Kusamalira Madzi Otayira: Njirayi imapanga madzi otayira omwe amafunika kusamalidwa bwino ndikutayidwa, zomwe zimawonjezera ndalama zogwirira ntchito.
Kafukufuku ndi chitukuko chamtsogolo cholinga chake ndi kuthana ndi mavutowa mwa:
Kukonza Zipangizo za Electrode: Kupanga zipangizo za electrode zokhazikika komanso zothandiza kuti muchepetse kugwiritsa ntchito ndikuwonjezera magwiridwe antchito.
Kukonza Mphamvu Yogwiritsa Ntchito Mphamvu: Kugwiritsa ntchito njira zamakono zopangira magetsi, monga pulsed DC, kuti muchepetse kugwiritsa ntchito mphamvu ndikuwonjezera magwiridwe antchito a chithandizo.
Kupititsa patsogolo Kusamalira Madzi Otayira: Kupanga njira zatsopano zochepetsera madzi otayira ndi kuwalitsa mtengo, monga kusintha madzi otayira kukhala zinthu zina zothandiza.
Pomaliza, magetsi a DC amagwira ntchito yofunika kwambiri pakukonza madzi akuda pogwiritsa ntchito magetsi, kupereka njira yothandiza, yosawononga chilengedwe, komanso yothandiza pochotsa zinthu zosiyanasiyana zodetsa. Ndi kupita patsogolo ndi kukonza bwino, kukonza madzi akuda pogwiritsa ntchito magetsi pogwiritsa ntchito magetsi kwatsala pang'ono kukhala njira yothandiza komanso yokhazikika yothanirana ndi mavuto apadziko lonse lapansi okhudza kukonza madzi akuda.
