A na nka sebelisa Aluminium Sulfate ka letamong la ho sesa?

Ho boloka boleng ba metsi a letamo la ho sesa ho bohlokoa bakeng sa ho netefatsa boiphihlelo bo bolokehileng le bo monate ba ho sesa.K'hemik'hale e 'ngoe e tloaelehileng e sebelisoang ho hloekisa metsi keAluminium Sulfate, motsoako o tsejoang ka katleho ea oona ho hlakisa le ho leka-lekanya metsi a letamo.

Aluminium sulfate, eo hape e tsejoang ka hore ke alum, e ka sebetsa joalo ka flocculants ka pheko ea metsi ea letamo la ho sesa, e thusa ho tlosa likaroloana tse emisitsoeng le litšila.Sena se ka etsa hore metsi a hlake le ho ntlafatsa botle le polokeho ka kakaretso ea letamo.

Mokhoa oa ho Hlakisa:

Aluminium sulfate e tšoasa likaroloana tse fanyehiloeng, tse kang litšila, lithōle le likokoana-hloko, e leng se etsang hore li lule ka tlas'a letamo.Tšebeliso ea kamehla ea aluminium sulfate e thusa ho boloka ho hlaka ha metsi le ho thibela ho bokellana ha lintho tse sa batleheng.

Taolo ea pH:

Ntle le litšobotsi tsa eona tse hlakisang, aluminium sulfate e boetse e susumetsa maemo a pH a metsi a letamo.Etsa bonnete ba hore pH ea metsi a letamo e pakeng tsa 7.2 le 7.6, 'me kakaretso ea alkalinity e pakeng tsa 80 le 120 ppm.Haeba ho hlokahala, fetola pH ka ho sebelisa pH Minus kapa pH Plus 'me u fetole alkalinity kaofela u sebelisa pH Minus le setshelo sa TA.Le ka mohla u se ke ua eketsa aluminium sulfate ha ho sebelisoa letamo.

Maikutlo le Litaelo:

Tekanyo e nepahetseng:

Ho bohlokoa ho latela litataiso tse khothaletsoang tsa litekanyetso ha u sebelisa aluminium sulfate ka letamong la ho sesa.Tekanyetso e tloaelehileng ke 30-50 mg/L.Haeba metsi a le litšila haholo, ho hlokahala tekanyo e phahameng.Ho noa ho feteletseng ho tla etsa hore boleng ba pH bo theohe ka mokhoa o feteletseng, ho baka kotsi e ka bang teng ho lisebelisoa tsa letamo la ho sesa, hape ho tla fokotsa phello ea flocculation.Ka lehlakoreng le leng, ho fokotseha ho ka 'na ha se ke ha fana ka tlhaloso e sebetsang ea metsi.

Tlhokomelo ea Kamehla:

Teko ea khafetsa ea liparamente tsa metsi a matamo, ho kenyeletsoa pH, alkalinity, le maemo a aluminium sulfate, ho bohlokoa.Sena se tiisa hore metsi a lula ka har'a sebaka se khothalelitsoeng 'me se thusa ho thibela mathata afe kapa afe a ka hlahang ka lebaka la ho se leka-lekane ha lik'hemik'hale.

Aluminium sulfate e tlameha ho sebelisoa ka nepo ho latela litataiso tsa ts'ebeliso.E thusa ho felisa likaroloana tse emisitsoeng le ho leka-lekanya litekanyetso tsa pH, 'me e phetha karolo ea bohlokoa ho hloekisa litšila tsa metsi tsa letamo.Letamo le lokela ho lekoa khafetsa, 'me le latele mokhoa o nepahetseng oa tšebeliso ho beha lik'hemik'hale tsa letamo la ho sesa ka mokhoa o sireletsehileng.
