Kamoo PAC e Ntlafatsang Katleho ea Phekolo ea Metsi ea Liindasteri

Sebakeng sa phekolo ea metsi ea indasteri, ho batla litharollo tse sebetsang hantle le tse sebetsang ke tsa bohlokoa. Hangata mekhoa ea indasteri e hlahisa metsi a mangata a litšila a nang le lintho tse thata tse emisitsoeng, lintho tse phelang le lintho tse ling tse silafatsang. Tlhokomelo e nepahetseng ea metsi ha e bohlokoa feela bakeng sa ho latela melao empa hape le bakeng sa ts'ebetso e tsitsitseng.Poly aluminium chloride(PAC) e phetha karolo ea bohlokoa ts'ebetsong ena ka ho thusa ho kopanya le ho phalla, e leng mehato ea bohlokoa ea ho arola litšila metsing.

Poly aluminium chloride ke k'hemik'hale e fapaneng ea phekolo ea metsi e sebetsang haholo-holo e le coagulant. Li-coagulants li thusa ho senyeha ha likaroloana tsa colloidal ka metsing, ho li lumella ho bokellana ka har'a lihlopha tse kholoanyane, tse boima tse ka tlosoa habonolo ka sedimentation kapa filtration. Sebopeho se ikhethileng sa PAC, se khetholloang ke marang-rang a rarahaneng a aluminium oxyhydroxide polymers, se nolofalletsa ho etsa lihlopha tse kholoanyane le tse teteaneng ha li bapisoa le li-coagulants tse tloaelehileng tse kang aluminium sulfate.

Melemo ea Bohlokoa ea ho Sebelisa PAC ho Phekolo ea Metsi ea Indasteri

Matlafatso ea Coagulation le Flocculation

PAC e bonts'a thepa ea boleng bo holimo ha e bapisoa le li-coagulant tsa setso joalo ka aluminium sulfate. Sebopeho sa eona sa polymeric se lumella ho bokellana ka potlako ha likaroloana tse ntle, ho etsa lihlopha tse kholoanyane le tse teteaneng. Sena se lebisa ho sedimentation e sebetsang haholoanyane le ho sefa, ho fella ka metsi a hlakileng haholoanyane.

Bophara ba pH Range Ka katleho

O mong oa melemo ea bohlokoa ea PAC ke bokhoni ba eona ba ho sebetsa ka bokhabane holim'a mefuta e mengata ea pH (5.0 ho isa ho 9.0). Sena se etsa hore e loketse ho hloekisa mefuta e fapaneng ea metsi a litšila a indasteri ntle le ho hloka phetoho e kholo ea pH, ho boloka nako le litšenyehelo tsa ts'ebetso.

Molumo o Fokotsoeng oa Sludge

PAC e hlahisa litšila tse nyane ha e bapisoa le li-coagulants tse ling, kaha e hloka litekanyetso tse tlase le lithuso tse fokolang tsa lik'hemik'hale ho fihlela sephetho se lakatsehang. Sena ha se fokotse feela litšenyehelo tsa ho sebetsana le litšila le ho lahla empa hape se fokotsa sebaka sa tikoloho ea ts'ebetso ea kalafo.

Katleho e Ntlafetseng ea ho Filtration

Ka ho hlahisa li-flocs tse hlophisitsoeng hantle, PAC e ntlafatsa ts'ebetso ea lits'ebetso tsa filthara tse tlase. Metsi a hloekileng a tsoang mothating oa ho sefa a eketsa nako ea bophelo ea lihloela le ho fokotsa litlhoko tsa tlhokomelo.

Tšebeliso e Tlaase ea Lik'hemik'hale

Ho sebetsa hantle haholo ha PAC ho bolela hore ho hlokahala lik'hemik'hale tse nyane ho fihlela litholoana tse nepahetseng. Sena se fetolela ho boloka litšenyehelo le phokotso ea phello e ka bang teng tikolohong ea lik'hemik'hale tse setseng metsing a hloekisitsoeng.

Likopo tsaPAC ho Phekolo ea Metsi ea Liindasteri

PAC e sebelisoa ho pholletsa le liindasteri tse fapaneng, ho kenyelletsa:

Indasteri ea Masela:Ho tlosa lidae le litšila tsa tlhaho metsing a litšila.

Ho Etsa Lipampiri:Ho ntlafatsa ho hlaka le ho tlosoa ha mebala ka metsing a sebetsang.

Oli le Khase:Ho hloekisoa ha metsi a hlahisoang le ho hloekisa litšila.

Lijo le Seno:Ho etsa bonnete ba ho latela litekanyetso tse thata tsa ho tsoa.

Ha liindasteri li ntse li leka ho sebelisa mekhoa e metle, PAC e hlaha e le khetho e tšoarellang. Ho sebetsa hantle ha eona litekanyetsong tse tlase, tlhahiso e fokotsehileng ea liretse, le bokhoni ba ho kopanya ka mokhoa o se nang moeli le litsamaiso tse teng tsa kalafo li tsamaisana le sepheo sa ho fokotsa tšebeliso ea lisebelisoa le ho fokotsa litšila.

Ka ho kenyelletsa PAC lits'ebetsong tsa tlhoekiso ea metsi, liindasteri li ka fumana litšila tse hloekileng, tsa latela melao ea tikoloho, le ho kenya letsoho mekhoeng e tsitsitseng ea taolo ea metsi. Bakeng sa liindasteri tse batlang ho ntlafatsa lits'ebetso tsa tsona tsa ho hloekisa metsi, PAC e fana ka tharollo e tšepahalang le e netefalitsoeng ho fihlela litlhoko tsa liphephetso tsa sejoale-joale tsa tlhoekiso ea metsi.
