maemo a tshebediso ya polyaluminium ferric chloride
1. Masepala Kalafo ea Metsi
Ho noa Ho Hloekisa Metsi
Ho tlosa bolwetse le ho tlosa bolele: e ka tlosa lintho tse tiileng tse emisitsoeng, bolele le litšila tsa colloidal ka katleho metsing a tala. E ntse e boloka phello e ntle ea ho phaphamala tikolohong e mocheso o tlase (ka tlase ho 5℃), e loketseng kalafo ea mohloli oa metsi mariha.
Ho tlosoa ha tšepe e boima: ho na le adsorption e matla hoo e ka bang caSebokaho sireletsa litšepe tse boima tse chefo tse kang arsenic (As) le loto (Pb), ho netefatsa hore metsi a litšila a fihlela litekanyetso tsa bohloeki ba metsi a nooang.
Tšebeliso fekthering ea kalafo ea likhoerekhoere
Ho tlosa metsi a seretse: ho potlakisa ho dula ha seretse ka tankeng ya sedimentation ya mantlha/tanka ya sedimentation e habeli, ho fokotsa dintho tse fanyehilweng (SS) le tlhokeho ya oksijene ya dikhemikhale (COD), le ho fokotsa mojaro wa kalafo e latelang.
Likhoerekhoere tsa malapeng tsa litoropong: Ha ho phekoloa likhoerekhoere tsa malapeng tse nang le mafome a mangata, floc e thehoa kapele le ka mokhoa o kopaneng, 'me lebelo la ho lula le phahame ka holimo ho 30% ho feta la li-coagulant tsa setso (tse kang PAC).
2. Phekolo ea metsi a litšila a indasteri
Ho etsa pampiri/ho daea metsi a litšila
Ho tlosa 'mala le ho senyeha ha oona: ho tlosa ka katleho mebala ea dae (joalo ka lidae tse arabelang, lidae tsa asiti) le lignin, sekhahla sa ho tlosoa ha chromaticity se feta 85%, 'me ho ntlafatsa ho bola ha metsi a litšila.
Phokotso ea COD: bakeng sa metsi a litšila a tlhaho a nang le bongata bo phahameng, tekanyo e fokotseha ka 20% ha e bapisoa le aluminium sulfate, e leng se fokotsang litšenyehelo tsa kalafo. Metsi a litšila a oli le a morafo
Karohano ea oli: ka ketso ea ho se nke lehlakore ha tjhaja ho roba emulsion kapele, ho monya litšila tsa peterole, ho loketse tšimo ea oli, ho sebetsa ka metsi a litšila.
Ho hlwekisa metsi a morafong: ho tlosa tshepe (Fe²⁺), manganese (Mn²⁺), sulfide le diminerale tse ding ka nako e le nngwe, ho rarolla bothata ba ho ba le tšilafalo le ditshila tse boima metsing a morafong.
Metsi a litšila a lijo/meriana
3. Tsosoloso ea tikoloho le tsamaiso ea tikoloho
Kalafo ea metsi a matšo le a nkhang hampe
Ntlafatso ea ponaletso: ho na ha bolele le lintho tse fanyehiloeng ka tlhaho ka potlako, ntlafatso e atlehang ea ponaletso ea noka, ho thibela ho qhoma ha bolele.
Tlhoekiso ea letamo la metsi a pula
Kalafo ea metsi a nang le mongobo o fokolang: e ikamahanya habonolo le metsi a nang le mongobo o fokolang tsamaisong ea pokello ea metsi a pula, 'me phello ea flocculation e tsitsitse.
4. Lintlha tsa tšebeliso le litlhahiso tsa ho ikamahanya le maemo a sebaka
| Litšobotsi tsa sebaka | Bophahamo ba PAFC | litaba li hloka tlhokomelo |
| Metsi a nang le sefefo se bataletseng ( | Sekhahla sa hydrolysis se potlakile 'me li-floc li teteaneng | Ha ho hlokahale lisebelisoa tse ling tsa ho futhumatsa |
| Metsi a litšila a nang le chromaticity e phahameng (khatiso le ho daea) | Karolo ea letsoai la tšepe e ntlafatsa bokhoni ba ho tlosa 'mala | Laola pH 5-10 ho qoba pula ea li-ion tsa tšepe |
| Metsi a litšila a nang le oli e ngata | Tšusumetso ea ho roba lebese e ntle 'me ho lahla mobu ho potlakile | E lokela ho kopanngoa le mokhoa oa ho phaphamala ha moea ho matlafatsa karohano ea oli |
| Metsi a morafo a thata haholo | Li-ion tse ngata tsa tšepe lia tlosoa ka nako e le 'ngoe | Hlahloba bokahare ba aluminium/tshepe e setseng kgafetsa |
