Ho ile ha phethoa ka hore ha pH ea boleng e le pakeng tsa 11 le 13, PAC e ile ea qala ho eketsoa le ho tsosoa ka metsotso e 2, ebe PAC e kenngoa le ho hlohlelletsoa metsotso ea 3, phello ea phekolo e ne e le molemo ka ho fetisisa.
Zhou Danni (2016) le ba bang ba ile ba ithuta phello ea phekolo ea PAC + PAM ka likhoerekhoere tsa malapeng, ba bapisa phello ea phekolo ea accelerator ea likokoana-hloko le antidote ea likokoana-hloko, 'me ba fumana hore PAC + PAM e ne e le molemo ho feta mokhoa oa phekolo ea likokoana-hloko ka phello ea ho tlosoa ha oli, empa PAC + PAM e ne e le betere ho feta mokhoa oa phekolo ea likokoana-hloko ka chefo ea boleng ba metsi.
Wang Zhizhi (2014) le ba bang. O ithutile mokhoa oa kalafo oa ho phekola metsi a litšila a sethaleng sa papermaking ka PAC + PAM coagulation e le karolo ea mokhoa. Ha tekanyo ea PAC e le 250 mg / L, tekanyo ea PAM ke 0.7 mg / L, 'me boleng ba pH bo batla bo sa nke lehlakore, sekhahla sa ho tlosa COD se fihla ho 68%.
Zuo Weiyuan (2018) le ba bang ba ithutile le ho bapisa phello e tsoakiloeng ea flocculation ea Fe3O4 / PAC / PAM. Tlhahlobo e bontša hore ha karolelano ea tse tharo e le 1: 2: 1, phello ea phekolo ea ho hatisa le ho daea metsi a litšila ke eona e molemo ka ho fetisisa.
LV sining (2010) et al. O ithutile phello ea kalafo ea motsoako oa PAC + PAM holim'a metsi a litšila a bohareng. Patlisiso e bonts'a hore phello e kopaneng ea flocculation ke eona e ntle ka ho fetisisa tikolohong ea asiti (pH 5). Tekanyetso ea PAC ke 1200 mg / L, tekanyo ea PAM ke 120 mg / L, 'me sekhahla sa ho tlosa cod se feta 60%.
1.3 metsi a litšila a lik'hemik'hale tsa mashala le ho hloekisa metsi a litšila
Yang Lei (2013) le ba bang. O ithutile phello ea coagulation ea PAC + PAM kalafong ea metsi a litšila a indasteri ea mashala, a bapisa moferefere o setseng tlasa likhakanyo tse fapaneng, mme a fana ka litekanyetso tse fetotsoeng tsa PAM ho latela moferefere o fapaneng oa pele.
Fang Xiaoling (2014) le ba bang ba bapisa phello ea coagulation ea PAC + Chi le PAC + PAM holim'a metsi a litšila a hloekisang. Ba fihletse qeto ea hore PAC + Chi e na le phello e ntle ea flocculation le katleho e phahameng ea ho tlosa COD. Liphetho tsa liteko li bonts'itse hore nako e nepahetseng ea ho sisinyeha e ne e le metsotso e 10 mme boleng bo nepahetseng ba pH e ne e le 7.

Wu Jinhua (2017) le ba bang. O ithutile kalafo ea metsi a litšila a lik'hemik'hale tsa mashala ka ho kopanya. PAC ke 2 g / L le PAM ke 1 mg / L. teko e bontša hore pH e ntle ka ho fetisisa ke 8.
Guo Jinling (2009) le ba bang. O ile a ithuta phello ea phekolo ea metsi ea motsoako oa motsoako 'me a nka hore phello ea ho tlosa e ne e le molemo ka ho fetisisa ha tekanyo ea PAC e ne e le 24 mg / L le PAM e le 0.3 mg / L.
Lin Lu (2015) le ba bang. E ithutile phello ea flocculation ea motsoako oa pac-pam holim'a oli ea emulsified e nang le metsi a litšila tlas'a maemo a fapaneng, 'me a bapisa phello ea flocculant e le' ngoe. Tekanyetso ea ho qetela ke: PAC 30 mg / L, pam6 mg / L, mocheso o teng 40 ℃, boleng ba pH bo sa nke lehlakore le nako ea sedimentation ho feta metsotso e 30. Tlas'a maemo a matle ka ho fetisisa, katleho ea ho tlosa COD e fihla hoo e ka bang 85%.
2 sephetho le litlhahiso
Motsoako oa polyaluminium chloride (PAC) le polyacrylamide (PAM) e 'nile ea sebelisoa haholo likarolong tsohle tsa bophelo. E na le bokhoni bo boholo tšimong ea ho hloekisa metsi a litšila le litšila, 'me boleng ba eona ba indasteri bo hloka ho hlahlojoa ho ea pele.
Mokhoa o kopanetsoeng oa PAC le PAM haholo-holo o itšetlehile ka ductility e babatsehang ea ketane ea PAM macromolecular, e kopantsoeng le Al3 + ho PAC le - O ho PAM ho theha mohaho o tsitsitseng oa marang-rang. Sebopeho sa marang-rang se ka koahela litšila tse ling tse kang likaroloana tse tiileng le marotholi a oli, kahoo se na le phello e babatsehang ea phekolo bakeng sa metsi a litšila a nang le mefuta e mengata ea litšila, haholo-holo bakeng sa ho phela hammoho ha oli le metsi.
Ka nako e ts'oanang, motsoako oa PAC le PAM le ona o na le liphoso. Likahare tsa metsi tsa flocculate e entsoeng li phahame, 'me mohaho oa eona o tsitsitseng o ka hare o lebisa litlhoko tse phahameng tsa phekolo ea bobeli. Ka hona, nts'etsopele e tsoelang pele ea PAC e kopantsoeng le PAM e ntse e tobana le mathata le mathata.
