Lik'hemik'hale tsa kalafo ea Sewage

Phekolo e litšila ke mokhoa o rarahaneng o hlokang hore ho sebelisoe lik'hemik'hale ho thusa metsi. Li-flocculants ke e 'ngoe ea lik'hemik'hale tsa bohlokoa tse bapala karolo ea bohlokoa ha u tšoaroa. Sengoliloeng sena se tla kenyelletsa litekanyetso tsa lik'hemik'hale tsa kalafo ea li-coufages, indasteri ea ts'ebeliso ea lipalesa, karolo ea lik'hemik'hale tsa Serage le tlhokomeliso ea ho sebelisa li-flocculants.

Tekanyetso ea lik'hemik'hale tsa kalafo ea likheo tsa Sewage e ipapisitse le boleng ba likhopolo tsa kalafo le maemo a kalafo le maemo a nnete. Lintlha tse latelang ke mehlala ea litekanyetso tsa lik'hemik'hale tse tloaelehileng tsa Sewadage:

Polyaluminium chloride (pac):Hangata e sebelisoa e le lipalesa joalo ka ha ho ka etsahala ka linoko tse qotsitsoeng hampe hore li hlahise li-micelle tsa hydroxide ho tlosa li-soids tse emisitsoeng tsa tšepe le li-Ions tsa tšepe. Maemong a tloaelehileng, litekanyetso tsa metsi a tala li mabapi le ligrama, empa litekanyetso tsa nnete li hloka ho fetoloa ho latela boleng ba metsi le maemo a mmele.

Polycerlaylamide (Pam):e sebelisoang joalo ka koluoa ​​ea ho ntlafatsa matla le botsitso ba lipalesa. Ka kakaretso e sebelisoa hammoho le polyaluminium chloliminium chloliminium chloliminium, litekanyetso tsa metsi a tala li nka ligrama tse 'maloa, empa litekanyetso tsa bonnete.

Li-flocculants li sebelisoa haholo kalafong ea metsi a senyang, haholo-holo ho kenyeletsa le mekhahlelo e latelang:

Phekolo ea litšila tsa indasteri: metsi a senya a indasteri a na le metsi a senya a indasteri a nang le metsi a mangata a indasteri a emisitsoeng a li-solar tsa ashpeds, tšepe ea tšepe e boima le liporofeta tsa maoatle le lipelaelo tsa maoatle le liporona tsa maoatle Ts'ebeliso ea lipalesa e ka tlose likotlo tsena hantle 'me u hloekise metsi a senyehileng.

Phekolo ea likokoana-hloko ea likokoana-hloko: Thes ea lapeng e na le lintho tse ngata tse tsoang manyolo le li-solisid tse emisitsoeng. Tšebeliso ea lipalesa e ka tlosa tšilafalo tsena hantle 'me u ntlafatse boleng ba metsi.

Litšila tsa metsi a polasi ea metsi: metsi a litšila a nang le lefu la manyolo, ammonia nitrogen le lintho tse ling tse kotsi. Tšebeliso ea lipalesa e ka tlosa tšilafalo tsena hantle 'me u ntlafatse boleng ba metsi.

Metsi a nang le litšila: Ts'ebeliso ea lipalesa e ka tlose ka katleho e emisitsoeng ea litlou tse thata, li-Ion tsa tšepe le liporofeta tsa manyolo ka metsing ebe li ntlafatsa boleng ba metsi.

Mesebetsi ea lik'hemik'hale tsa SewAge e kenyelletsa mekhahlelo e latelang:

Ho tlosoa ha li-solads tse emisitsoeng: ka ketso ea li-flocculants, li-solads tse senyehileng metsing a litšila li kopantsoe ka makhasi a ho nolofalletsa ho nolofatsa.

Ho tlosoa ha tšepe e boima: Ka ketso ea li-flocculants, tšepe ea tšepe e boima ea metsi a litšila a fetoloa hore li-hydroxx tsa ho tlosoa.

Ho tlosoa ha batho ba polao ea manyolo: Ka ketso ea lipalesa tsa metsi a litšila li fetoloa likhalase tsa ho tlosoa.

Phetoho ea PH: Fetola PH ea metsi a senyehileng ka ketso ea alkali kapa acid ho hloekisa metsi a litšila.

Lintho tsa ho ela hloko ha u sebelisa li-flocculants:

Khetha phallo e loketseng: Li-flocculants tse fapaneng li na le mesebetsi le litlamorao tse fapaneng. Hoa hlokahala ho khetha lipalesa tse nepahetseng ho latela boemo ba nnete.

Laola litekanyetso tsa meriana: Tekanyetso e sa lekaneng e tla ama phello, 'me litekanyetso tse feteletseng li tla baka litšila le tahlehelo ea moruo. Ka hona, hoa hlokahala ho laola litheko tse nepahetseng ho latela boemo ba nnete.

Hlohlelletsa ka botlalo: Hlohlela ha lipalesa le metsi hantle ho qhibiliha ka botlalo ebe u amohela.

Ela hloko mocheso le boleng ba PH: boleng ba mocheso:
