Ho sebelisoa phello ea pac 'me pam e sebelisoa libakeng tsohle tsa kalafo, empa mekhoa ea kalafo e fapane le maemo a fapaneng a ho sebetsa le tikoloho ea kalafo.
1.1 DOMECESTACE LIWAGE LE LITLHAKISO TSE KHOLO
Zhao Yenyang (2013) 'me ba bang ba ile ba leka ho ba le koluoa ea Pam e le thuso ea bo-ramahlale ho pac le pafc ka ho sebelisa mokhoa oa tlhahlobo ea indor. Teko e fumanoeng hore phello ea caland ea bo-pac kamora hore ho kopitsoa haholo ho ile ha eketsoa haholo.
Wang Muting (2010) mme ba bang ba ithute phello ea kalafo ea Pac + pasmuoeng a lehae, mme ba ithuta letsopa la Cod ho tlosoa le liteko tse ling ka liteko tsa Orthogonal.
Lin yingzi (2014) et al. O ithutile phello e ntlafalitsoeng ea ho bakooa ha Pac le pam ho motho ea ka banyenyane ka semela sa kalafo ea metsi. Yang Hongmei (2017) et al. O ithutile phello ea kalafo ea ts'ebeliso ea metsi a Kimchi, mme a nahana hore boleng ba PH bo ne bo le 6 joang.
Fu peiqian (2008) et al. O ithutile phello ea lipalesa tsa metsoako e sebelisitsoeng ho nchafatsa metsi. Ka ho lekanya litlamorao tsa ho itlosa ha litlamorao tse kang turbidity, TP, cod le phospuphate limppole tsa metsi, ho fumanoa phospole ea metsi
Cao Longtian (2012) 'Me ba bang ba amohela mokhoa oa ho kenya sekhahla sa sekhahla sa bohato ba ho rala butle butle-butle China ka lebaka la mocheso o tlase mariha.

Zhang ronhe (2015) et al. O ithutile phello ea maqephe a maqephe a chithen (CTS) le pugulant kalafong ea metsi a litšila, mme a fumana hore ho ne ho le molemo ho eketsa Chinosan
Litefiso tsa ho tlosa li-cod le turbidity li ile tsa eketseha ka 13.2% le 5.9%.
Xie lin (2010) o ile a ithuta ka phello ea Pac le Pam kalafo ea metsi a litšila tsa pampiri.
Liu ziqiang (2013) 'Me ba bang ba ne ba sebelisa lipalesa tsa pac le pac e kopaneng le fracculante e kopaneng le ea ultrasonitic ho phekola khatiso le ho bolaea metsi a litšila. E ile ea fihlela qeto ea hore ha boleng ba PH e ne e le pakeng tsa 11 le 13, Pac e ile ea qala ho eketsoa ka lekhetlo la 2 metsotso e 2, ebe tšusumetso ea kalafo e ne e le eona e ntle ka ho fetisisa.
Zhou danni Pac + Pam o ne a le betere ho feta mokhoa oa kalafo oa kalafo ka chefo ea boleng ba metsi.
Wang Zhizhi (2014) et al. O ithutile mokhoa oa kalafo oa ho phekola lipampiri tsa limela tsa mahareng tsa pampiri ka sekepe ka Pac + pam coagganas e le karolo ea mokhoa. Ha litekanyetso tsa Pac ke 250 mg / l, litekanyetso tsa pam ke 0.7 mg / boleng ba ho tlosa li-cod bo fihla ho 68%.
Zuo Weiyuan (2018) 'Me ba bang ba ne ba ithuta ba ba bapisa phello e kopaneng ea fe3o4 / Pac / Pam. Teko e bontša hore ha karohano ea tse tharo ke 1: 2: 1, phello ea kalafo ea limela le ho bolaoa ke metsi a litšila ho fetisisa.
Lv singling (2010) et al. Ho kopantsoe kalafo ea kalafo ea Pac + Pam ka metsi a litšila a bohareng. Patlisiso e bontša hore phello ea lipalesa e nang le lipalesa e ntle ka ho fetisisa tikolohong ea acidic (ph 5). Ka tekanyetso ea Pac ke 1200 mg / l, litekanyetso tsa pam ke 120 mg / l, sekhahla sa likhomo se feta 60%.
1.3 Coal ea litlolo tsa lik'hemik'hale ea lik'hemik'hale le ho ntlafatsa metsi a litšila
Yang lei (2013) et al. Ha a ithuta phello ea coaging of Pac + Pam ka lits'oants'o tsa mashala, ha ho bapisoa le koluoa e mengata, mme a fana ka litekanyetso tse lokiselitsoeng tsa Pam ho latela tumello e fapaneng ea Pam ho latela tumello e fapaneng ea Pam ho latela tumello e fapaneng ea Pam ho latela tumello e fapaneng ea Pam ho latela tumello e fapaneng ea Pam ho latela tumello e fapaneng ea Pam ho latela tumello e fapaneng ea Pam ho latela Turbidity ea pele.
Fang Xiaoling (2014) Mme ba bang ba bapisitse phello ea caland + chi le Pac + pam ka metsing a hloekileng a litšila. Ba ile ba fihlela qeto ea hore Pac + Chi o ne a e-na le phello e ntle ea lipalesa le mokhoa o phahameng oa ho tlosa li-cod. Liphetho tsa liteko li bontšitse hore nako ea ho hlasimoha e ne e le metsotso e 10 min le boleng ba PH le boleng ba PH e ne e le 7.
Dng Lei (2017) et al. O ithutile phello ea lipalesa tsa pac + pam ka metsi a litšila a metsi, 'me sekhahla sa likhopo se fihlile ho feta 80%.
Wu Jinhua (2017) et al. O ithutile kalafo ea metsi a litšila a lik'helemi tsa lik'hemik'hale ka ho qhekelloa ke ho hola. Pac ke 2 G / L le Pam ke 1 MG / L. Teko e bontša hore boleng bo botle ba PH bo joalo ka 8.
Guo Jinling (2009) et al. E ne e ithuta phello ea kalafo ea metsi ea metsi a nang le matla a ho tlosa metsi le ho nkoa e le tse ntle ka ho fetisisa ha phello ea pac e ne e le 5 mg / l.
Lin Lu (2015) et al. Ho ne ho thula matla a lipalesa tsa 'mala oa pac-Pam ka oli e nang le litšila tse nang le metsi a senya tlasa maemo a fapaneng,' me u ba bapisoa le litlamorao tsa lipalesa tse le 'ngoe. Tekanyetso ea ho qetela ke: Pac 30 mg / L, PAM6 MG / L, boleng ba mocheso ba 40 ℃, nako ea ho se nke lehlakore ea PH. Tlas'a maemo a matle ka ho fetisisa, ho tlosoa ha eona ho tlosoa ha cod ho fihlela 85%.
Phoso le litlhahiso
Motsoako oa polyaluminium chloniminium chlonime (pac) le polyaczerlamide (pam) e sebelisoa haholo maetong ohle a bophelo. E na le bokhoni bo boholo lefapheng la metsi a senya a metsi le a sesupo, mme boleng ba eona ba indasteri bo lokela ho hlahlojoa hape.
Mechanism ea ho kopanya ea Pac le Pam e itšetlehile haholo ka lebaka la kemiso ea Pam Macromolecular, e kopantsoeng le Al3 + ka Pac ho theha sebopeho se tsitsitseng sa marang-rang. Sebopeho sa marang-rang se ka kenya litšila tse ling tse kang likaroloana tse matla, kahoo e na le tšusumetso e ntle ea metsi a mefuta-fufule, haholo-holo bakeng sa bokhabane ba oli le metsi.
Ka nako e ts'oanang, motsoako oa Pac le Pam o boetse o na le likomelo. Maqhekatsi a lipalesa a thehileng a phahame, 'me sebopeho sa eona se ka hare ho lebisa litlhoko tse phahameng bakeng sa kalafo ea bobeli.
