Ferric Chloride e sebelisetsoa eng ho hloekisa metsi?

Ferric Chlorideke motsoako oa lik'hemik'hale o nang le foromo ea FeCl3. E sebelisoa haholo mekhoeng ea ho hloekisa metsi e le coagulant ka lebaka la katleho ea eona ea ho tlosa litšila le litšila metsing 'me ka kakaretso e sebetsa hantle ho feta metsi a batang ho feta alum. Hoo e ka bang 93% ea ferric chloride e sebelisoa ho hloekisa metsi, ke hore, metsi a litšila, likhoerekhoere, metsi a phehang le metsi a nooang. Ferric chloride e sebelisoa haholo-holo ka mokhoa o tiileng e le tharollo ea metsi le metsi a litšila.

Tšebeliso ea ferric chloride kalafo ea metsi:

1. Coagulation le Flocculation: E 'ngoe ea litšebeliso tsa mantlha tsa ferric chloride kalafong ea metsi ke e le coagulant. Ha e kenngoa metsing, ferric chloride e arabela ka metsi ho hlahisa ferric hydroxide 'me ea morao e hlahisa likaroloana tse emisitsoeng, lintho tse phelang le litšila tse ling ho etsa likaroloana tse kholoanyane tse boima tse bitsoang flocs. Joale li-flocs tsena li ka lula habonolo nakong ea sedimentation kapa ts'ebetso ea ho sefa, ho lumella ho ntšoa ha litšila metsing.

2. Ho Tlosa Phosphorus: Ferric chloride e sebetsa ka ho khetheha ho tlosa phosphorus metsing. Phosphorus ke limatlafatsi tse tloaelehileng tse fumanoang metsing a litšila, 'me maemo a feteletseng a ka lebisa ho eutrophication ho amohela libaka tsa metsi. Ferric chloride e etsa li-insoluble complexes tse nang le phosphorus, tse ka tlosoang ka pula kapa ho sefa, ho thusa ho fokotsa maemo a phosphorus metsing.

3. Ho Tlosoa ha Metal Metal: Ferric chloride e boetse e sebelisoa ho tlosa litšepe tse boima tse kang arsenic, lead le mercury metsing. Litšepe tsena li ka ba chefo haholo 'me tsa baka likotsi tse tebileng tsa bophelo bo botle haeba li le teng metsing a nooang. Ferric chloride e etsa li-insoluble metal hydroxides kapa metal oxychlorides, tse ka tlosoang ka mokhoa oa pula kapa oa ho sefa, ka katleho ho fokotsa bongata ba litšepe tse boima metsing.

4. Ho Tlosoa ha 'Mala le Monko: Ferric chloride e atleha ho tlosa' mala le metsoako e bakang monko ho tloha metsing. E etsa oxidize metsoako ea lintho tse phelang tse ikarabellang bakeng sa 'mala le monko, e li arola hore e be lintho tse nyenyane tse sa rateheng. Ts'ebetso ena e thusa ho ntlafatsa boleng bo botle ba metsi, ho etsa hore a lokele ho nooa, indasteri, kapa boithabiso.

5. Phetoho ea pH: Ka ho laola pH, ferric chloride e ka ntlafatsa ts'ebetso ea mekhoa e meng ea phekolo, e kang coagulation, flocculation, le disinfection. Sebaka se loketseng sa pH se ka thusa ho theha maemo a matle bakeng sa ho tlosa litšila le litšila metsing.

6. Taolo ea Lihlahisoa tsa Disinfection: Ferric chloride e ka thusa ho laola ho thehoa ha lihlahisoa tsa likokoana-hloko (DBPs) nakong ea phekolo ea metsi. Ha e sebelisoa hammoho le likokoana-hloko tse kang chlorine, ferric chloride e ka fokotsa ho thehoa ha DBPs tse kang trihalomethanes (THMs) le haloacetic acids (HAAs), tse ka 'nang tsa baka kankere. Sena se ntlafatsa polokeho le boleng ba metsi a nooang ka kakaretso.

7. Ho hloekisoa ha Sludge: Ferric chloride e boetse e sebelisoa mekhoeng ea ho ntša metsi a litšila libakeng tsa ho hloekisa metsi a litšila. E thusa ho lokisa seretse ka ho khothalletsa ho thehoa ha lihlopha tse kholoanyane, tse teteaneng, tse lulang ka potlako le ho lokolla metsi ka katleho. Sena se fella ka ts'ebetso e ntlafetseng ea ho ntša metsi le ho fokotsa molumo oa litšila, ho etsa hore ho be bonolo le ho boloka chelete e ngata ho sebetsana le ho lahla litšila.

Ferric Chloride e bapala karolo ea bohlokoa likarolong tse fapaneng tsa pheko ea metsi, ho kenyelletsa le coagulation, phosphorus le ho tlosoa ha tšepe e boima, ho tlosa mebala le monko, ho lokisoa ha pH, ho thibela likokoana-hloko ka lihlahisoa, le ho ntša metsi a litšila. Ho ikamahanya le maemo le ho sebetsa ha eona ho etsa hore e be k'hemik'hale ea bohlokoa kalafong ea metsi a nooang le metsi a litšila, e thusang ho netefatsa polokeho, boleng le botsitso ba mehloli ea metsi.
