Melemo ea polyaluminium chloride e sebetsang hantle haholo kalafong ea metsi a litšila

Ka ho potlakisa ha indasteri, phallo ea likhoerekhoere e fetohile taba e kholo ts'ireletsong ea tikoloho ea lefats'e. Moko oa ho hloekisa likhoerekhoere ke khetho le tšebeliso eaflocculantsts'ebetsong ea tlhoekiso. Lilemong tsa morao tjena, polyaluminium chloride e sebetsang hantle haholo (PAC), e le flocculant ea bohlokoa, butle-butle e fetohile "sehlahisoa sa linaleli" indastering ea ho hloekisa likhoerekhoere ka lebaka la ts'ebetso ea eona e babatsehang le litebello tse pharaletseng tsa kopo.

Polyaluminium chloride ke motsoako oa polymer oa inorganic o nang le phello e matla ea flocculation. E fumanoa ka karabelo ea polymerization ea aluminium chloride le aluminium hydroxide tlas'a maemo a itseng. Ha ho bapisoa le litlolo tse tloaelehileng tsa letsoai la aluminium (tse kang aluminium sulfate, aluminium letsoai coagulant, joalo-joalo), polyaluminium chloride e sebetsang hantle haholo e na le matla a matla a ho tlosa litšila, haholo-holo ha e sebetsana le turbidity e phahameng le tšilafalo e boima ea oli. Tshebetso e ikhetha haholo ha ho tluoa tabeng ea boleng ba metsi. E 'nile ea sebelisoa haholo libakeng tse ngata tse kang phekolo ea likhoerekhoere tsa masepala, phekolo ea likhoerekhoere tsa indasteri, le phekolo ea likhoerekhoere tsa malapeng.

Melemo ea polyaluminium chloride e sebetsang hantle haholo

1. Phello ea flocculation e tsoteha

Polyaluminium chloride e sebetsang hantle haholo e ka etsa ka potlako palo e kholo ea li-flocs tse ntle ka metsing, ka ho etsa joalo ka mokhoa o atlehileng oa ho bapatsa lintho tse tiileng tse emisitsoeng, lintho tsa colloidal le likokoana-hloko ka metsing. E ka khabisoa ka potlako le ho tlosa likaroloana tse emisitsoeng, mafura, li-ion tse boima tsa tšepe le litšila tse ling metsing. Haholo-holo ha u sebetsana le boleng bo rarahaneng ba metsi, phello e phahame haholo ho feta mekhoa e tloaelehileng ea letsoai la aluminium. Ts'ebetsong ea likhoerekhoere, polyaluminium chloride e sebetsang hantle haholo e ka eketsa lebelo la ho lokisa tanka ea sedimentation ka nako e khuts'oane, kahoo e khutsufatsa haholo potoloho ea likhoerekhoere.

2.Wide mefuta e fapaneng ya tshebediso

Polyaluminium chloride e sebetsang hantle haholoe ka ikamahanya le maemo a sa tšoaneng a boleng ba metsi, ho akarelletsa le metsi a mangata a litšila, likhoerekhoere tse nang le mafura a mangata, metsi a nang le litšepe tse boima, le metsi a tlaase a mocheso a tlaase, a bontšang ho ikamahanya le maemo ho matla. E ka khona ho tlosa boholo ba lintho tse thata tse emisitsoeng le lintho tse silafatsang metsing, 'me e ka sebelisoa haholo ho hloekisa likhoerekhoere mafapheng a fapaneng a kang tsamaiso ea masepala, indasteri le merafo. Mohlala, kalafong ea likhoerekhoere tsa malapeng, metsi a litšila a leloala, metsi a litšila a metallurgical, metsi a litšila a indasteri ea lijo le maemo a mang, polyaluminium chloride e sebetsang hantle haholo e ka fihlela litholoana tse ntle tsa kalafo.

3. Tekanyetso e tlase, ts'ebetso e phahameng le ho boloka matla

Polyaluminium chloride e sebetsang hantle haholo e etselitsoe ho fihlela litekanyetso tse tlase le phello e ntle ea flocculation. Tekanyetso bakeng sa turbidity e tlase ke 25-40% ea aluminium sulfate, 'me tekanyo ea turbidity e phahameng ke 10-25% ea aluminium sulfate. Sena ha se fokotse feela litšenyehelo tsa ho sebelisa lik'hemik'hale, empa hape se fokotsa tšebeliso ea matla le li-sludge ts'ebetsong ea ho hloekisa likhoerekhoere. Ka lebaka la mesaletsa ea eona e tlase ea aluminium, e fokotsa tšilafalo ea bobeli ea mehloli ea metsi mme e fokotsa haholo litšenyehelo tse akaretsang tsa ho hloekisa likhoerekhoere. Ka hona, e fetohile sesebelisoa sa bohlokoa sa ho boloka litšenyehelo le ho ntlafatsa ts'ebetso ea ts'ebetso e sebetsang.

4. Ho baballa tikoloho

Tšebeliso ea polyaluminium chloride e sebetsang hantle haholo e na le tšusumetso e fokolang tikolohong le masalla a tlase a aluminium. Ha ho bapisoa le lisebelisoa tse ling tsa lik'hemik'hale, polyaluminium chloride e bolokehile ho feta 'me e na le tšusumetso e fokolang ho pH le TA ea metsi a litšila, kahoo tlhokahalo ea lik'hemik'hale ho fetola pH le TA ea fokotseha. Haholo-holo mererong e meholo ea ho hloekisa likhoerekhoere le merero ea ts'ireletso ea tikoloho, e fetohile khetho e tala le e se nang tikoloho.

5. E loketse mocheso o tlase le phekolo ea metsi a turbidity e phahameng

Ho hloekisoa ha metsi linakong tsa mocheso o tlase ke phephetso e tloaelehileng. Haholo-holo mariha a batang, katleho ea li-flocculants tse ngata tsa setso e tla fokotseha haholo. Leha ho le joalo, polyaluminium chloride e sebetsang hantle haholo e ka tsoela pele ho boloka phello e phahameng ea flocculation tlas'a maemo a tlase a mocheso. Ho phaella moo, ha moferefere oa metsi o phahame, PAC e boetse e bontša bokhoni bo matla ba ho sebetsa 'me e ka khona ho tlosa likaroloana tse emisitsoeng le lintho tsa colloidal metsing. Bakeng sa metsi a nang le tšilafalo e boima ea oli, polyaluminium chloride e sebetsang hantle haholo le eona e na le phello e ntle haholo ea ho theola.

6. Ikamahanya le maemo a fapaneng a pH a boleng

Polyaluminium chloride ea boleng bo holimo e na le matla a ho ikamahanya le maemo a feto-fetohang a pH ea metsi 'me e ka sebetsa ka katleho maemong a mangata a pH. Ka kakaretso, PAC e ka boloka phello e ntle ea flocculation ka metsing a nang le pH e tlase (e nang le asiti) kapa e phahameng (alkaline), e eketsang ts'ebetso ea eona tlasa maemo a fapaneng a boleng ba metsi. 5.0-9.0 vs 5.5-7.5

7. Ntlafatsa katleho ea sedimentation le ho fokotsa molumo oa seretse

Polyaluminium chloride e sebetsang hantle haholo e thusa ho potlakisa ho rarolloa ha likaroloana tse tiileng ka har'a likhoerekhoere le ho ntlafatsa ts'ebetso ea tanka ea sedimentation ka ho ntlafatsa letsoalo le botsitso ba li-flocs. Ho phaella moo, ka lebaka la tekanyo e phahameng ea polymerization ea polyaluminium chloride e sebetsang hantle haholo, li-flocs tse entsoeng li tiile 'me li lula ka potlako, kahoo li fokotsa bongata ba seretse se hlahisoang. Sena se bohlokoa haholo bakeng sa kalafo le ho lahloa ha seretse se latelang, 'me se ka fokotsa litšenyehelo le bothata ba kalafo ea seretse.

Mehlala ea ts'ebeliso ea polyaluminium chloride e sebetsang hantle haholo kalafong ea metsi a litšila

1. Phekolo ea likhoerekhoere tsa masepala

Sebakeng sa phekolo ea likhoerekhoere tsa masepala, polyaluminium chloride e sebetsang hantle haholo e ka sebelisoa haholo methating ea pele le ea bobeli ea kalafo ea limela tsa metsi. E ka khona ho tlosa lintho tse tiileng tse emisitsoeng, lintho tsa colloidal, libaktheria le likokoana-hloko tse ling ka metsing, ea ntlafatsa boleng ba metsi, 'me ea fana ka mohloli o phahameng oa metsi bakeng sa phekolo ea likokoana-hloko tse latelang. PAC e se e le e 'ngoe ea litsi tse atileng ka har'a lifeme tsa likhoerekhoere metseng e mengata ea lapeng le kantle ho naha.

2.Tlhaloso ea metsi a litšila ea indasteri

Lefapheng la kalafo ea metsi a litšila a indasteri, polyaluminium chloride e sebetsang hantle haholo le eona e sebelisoa haholo. E na le phello e ntle ea phekolo ho metsi a litšila a indasteri ho tloha khatisong le ho daea, ho etsa pampiri, letlalo, electroplating le liindasteri tse ling, 'me e ka khona ho tlosa litšila tse kang mebala, COD le BOD ka katleho. Ka mohlala, ka metallurgy, matla a motlakase, indasteri ea lik'hemik'hale, ho etsa pampiri, ho lokisa lijo le liindasteri tse ling, PAC e ka thusa ho tlosa litšepe tse boima, matheba a oli, likaroloana tse emisitsoeng le litšila tse ling metsing. Haholo-holo ha ho hloekisoa metsi a litšila a mafura, PAC e bontšitse bokhoni ba eona bo botle ba ho tlosa oli 'me e ka fokotsa haholo oli ea metsi.

3. Merafo ea ho hloekisa metsi a litšila

Sebakeng sa phekolo ea metsi a litšila a merafo, polyaluminium chloride e sebetsang hantle haholo e ka tlosa liminerale, sediment le lintho tse ling tse emisitsoeng ka metsing, ho fana ka ts'ehetso ea ho tsosolosa metsi le ho tsosolosa tikoloho libakeng tsa merafo. Kaha boleng ba metsi libakeng tsa merafo bo rarahane 'me hangata bo na le palo e kholo ea lintho tse tiileng tse emisitsoeng le litšepe tse boima, katleho e phahameng ea polyaluminium chloride e phahameng e ikhetha ka ho khetheha mofuteng ona oa ho hloekisa metsi a litšila.

Ka kakaretso,polyaluminium chloride e sebetsang hantle haholo, e le flocculant e babatsehang bakeng sa phekolo ea likhoerekhoere, e na le melemo ea bohlokoa ea tekheniki le ea tikoloho. Haholo-holo tabeng ea turbidity e phahameng, boleng ba metsi a rarahaneng, le tšilafalo e boima ea oli, e ka finyella liphello tse ntle haholo tsa phekolo.
