Lik'hemik'hale tsa ho hloekisa likhoerekhoere

Ho hloekisa metsi a litšila ke mokhoa o rarahaneng o hlokang hore ho sebelisoe lik'hemik'hale tse sa tšoaneng ho thusa ho hloekisa metsi.Li-flocculants ke e 'ngoe ea lik'hemik'hale tsa bohlokoa tse phethang karolo ea bohlokoa tsamaisong ea likhoerekhoere.Sehlooho sena se tla hlahisa ka ho qaqileng litekanyetso tsa lik'hemik'hale tsa phekolo ea likhoerekhoere, liindasteri tsa tšebeliso ea li-flocculants ka ho hloekisa likhoerekhoere, karolo ea lik'hemik'hale tsa likhoerekhoere, le mehato ea ho itšireletsa bakeng sa ho sebelisa li-flocculants.

Tekanyo ea lik'hemik'hale tsa phekolo ea likhoerekhoere e itšetlehile ka boleng ba likhoerekhoere, mokhoa oa phekolo le maemo a sebele.Mehlala e latelang ke ea litekanyetso tsa lik'hemik'hale tse tloaelehileng tsa likhoerekhoere:

Polyaluminium chloride (PAC):Hangata e sebelisoa e le flocculant, e ka itšoara ka likaroloana tsa colloidal tse qosoang hampe ho hlahisa li-micelles tsa hydroxide ho tlosa lintho tse tiileng tse emisitsoeng le li-ion tsa tšepe tse boima.Tlas'a maemo a tloaelehileng, tekanyo ea tone ka 'ngoe ea metsi a tala e ka ba ligrama tse mashome, empa tekanyo ea sebele e hloka ho fetoloa ho latela boleng ba metsi a tala le maemo a tshebetso.

Polyacrylamide (PAM):e sebelisoa e le coagulant ho ntlafatsa ho tiea le botsitso ba floc.Ka kakaretso e sebelisoa hammoho le polyaluminium chloride, tekanyo ea tone e le 'ngoe ea metsi a tala e ka ba ligrama tse' maloa, empa tekanyo ea sebele e hloka ho lokisoa ka nepo ho latela maemo a ts'ebetso le mefuta ea litšila.

Li-flocculants li sebelisoa haholo ho hloekisa metsi a litšila, haholo-holo ho kenyelletsa le mekhahlelo e latelang:

Phekolo ea metsi a litšila a indasteri: Metsi a litšila a indasteri a na le lintho tse ngata tse tiileng tse emisitsoeng, li-ion tsa tšepe e boima le litšila tse silafatsang.Tšebeliso ea li-flocculants e ka tlosa litšila tsena ka katleho le ho hloekisa metsi a litšila.

Tlhokomelo ea likhoerekhoere malapeng: likhoerekhoere tsa ka tlung li na le lintho tse ngata tse phelang le lintho tse tiileng tse fanyehiloeng.Tšebeliso ea li-flocculants e ka tlosa litšila tsena ka katleho le ho ntlafatsa boleng ba metsi.

Phekolo ea metsi a litšila a polasing: Metsi a litšila a polasing a na le lintho tse ngata tse phelang, ammonia nitrogen le lintho tse ling tse kotsi.Tšebeliso ea li-flocculants e ka tlosa litšila tsena ka katleho le ho ntlafatsa boleng ba metsi.

Metsi a litšila a indasteri: Tšebeliso ea li-flocculants e ka khona ho tlosa lintho tse tiileng tse emisitsoeng, li-ion tse boima tsa tšepe le lintho tse silafatsang ka metsing le ho ntlafatsa boleng ba metsi.

Mesebetsi ea lik'hemik'hale tsa likhoerekhoere e kenyelletsa haholo-holo lihlopha tse latelang:

Ho tlosoa ha lintho tse tiileng tse emisitsoeng: Ka ketso ea li-flocculants, lintho tse tiileng tse fanyehiloeng metsing a litšila li kopanngoa ho ba lihlopha ho etsa hore ho be le sedimentation le ho sefa.

Ho tlosoa ha li-ion tsa tšepe tse boima: Ka ts'ebetso ea li-flocculants, li-ion tsa tšepe tse boima ka metsing a litšila li fetoloa ho ba hydroxide precipitates bakeng sa ho tlosoa habonolo.

Ho tlosoa ha lintho tse silafatsang: Ka ts'ebetso ea li-flocculants, litšila tse tsoang metsing a litšila li fetoloa hore e be li-hydroxide precipitates kapa li entsoe ka oxidized hore e be lintho tse ling hore li tlosoe habonolo.

Phetoho ea pH: Fetola pH ea metsi a litšila ka ts'ebetso ea alkali kapa asiti ho hloekisa metsi a litšila.

Lintho tseo u lokelang ho li ela hloko ha u sebelisa li-flocculants:

Khetha flocculant e nepahetseng: Li-flocculants tse fapaneng li na le mesebetsi le litlamorao tse fapaneng.Hoa hlokahala ho khetha flocculant e loketseng ho ea ka boemo ba sebele.

Laola tekanyo ea meriana: Tekanyetso e sa lekaneng e tla ama phello, 'me tekanyo e feteletseng e tla baka tšenyo le tahlehelo ea moruo.Ka hona, hoa hlokahala ho laola tekanyo e nepahetseng ho latela boemo ba sebele.

Hlohlelletsa ka ho feletseng: Hlohlelletsa flocculant le metsi ka botlalo ho qhibiliha ka ho feletseng le ho itšoara.

Ela hloko mocheso le boleng ba pH: Thempereichara le boleng ba pH li na le tšusumetso ho phello ea flocculant 'me li hloka ho laoloa ka hloko.
