Izici Ezithinta Ukusebenza Kwe-Flocculant Ekuphathweni Kwamanzi Angcolile

Ekuphathweni kwamanzi amdaka, i-pH iyisici esibalulekile esithinta ngqo ukusebenza kahle kwamanzi amdaka.Ama-FlocculantLesi sihloko sigxila emthonjeni we-pH, i-alkalinity, izinga lokushisa, usayizi wezinhlayiya zokungcola, kanye nohlobo lwe-flocculant ekusebenzeni kahle kwe-flocculation.

Umthelela we-pH

I-pH yamanzi angcolile ihlobene kakhulu nokukhethwa, umthamo, kanye nokusebenza kahle kokuhlanganisa ama-flocculants. Izifundo zibonisa ukuthi uma i-pH ingaphansi kuka-4, ukusebenza kahle kokuhlanganisa ama-colloidal kuphansi kakhulu. Lokhu kungase kube ngenxa ye-pH ephansi yokuzinzisa izinhlayiya ze-colloidal emanzini angcolile, okwenza kube nzima ngama-flocculants ukuzihlanganisa ngempumelelo. Uma i-pH iphakathi kuka-6.5 no-7.5, ukusebenza kahle kokuhlanganisa ama-colloidal kuthuthuka kakhulu ngoba ukungazinzi kwezinhlayiya ze-colloidal kulolu hlu lwe-pH kuthuthukisa ukusebenza kwama-flocculants. Kodwa-ke, lapho i-pH idlula u-8, ukusebenza kahle kokuhlanganisa ama-coagulation kwehla kakhulu, mhlawumbe ngoba i-pH ephezulu ishintsha ibhalansi ye-ion emanzini angcolile, okuthinta kabi ama-flocculants.

Uma i-pH iphansi kakhulu, i-PAC ayikwazi ukwakha ama-floc ngempumelelo, futhi amaqembu e-anionic e-APAM azoncishiswa, okwenza ingasebenzi. Uma i-pH iphezulu kakhulu, i-PAC ishesha kakhulu, okuholela ekusebenzeni kabi, futhi i-CPAM ithambekele ekufakweni kwe-hydrolysis futhi ingasebenzi kahle.

Indima ye-Alkalinity

Ubuningi be-alkalinity ye-sewage buffers pH. Uma ubuningi be-sewage alkalinity bunganele, ngokuvamile kuyadingeka ukuyifaka ngamakhemikhali anjenge-lime ukuze kugcinwe ukuzinza kwe-pH okuthuthukisa umphumela omuhle kakhulu we-flocculation we-PAC. Ngokuphambene nalokho, lapho i-pH yamanzi iphezulu kakhulu, ama-asidi angadinga ukungezwa ukuze kwehliswe i-pH ibe yi-neutral, kuqinisekiswe ukusebenza kahle kwe-flocculants.

Umthelela Wezinga Lokushisa

Izinga lokushisa lamanzi amdaka nalo liyisici esibalulekile esithonya ukusebenza kahle kwe-flocculation. Emazingeni okushisa aphansi, amanzi amdaka abonisa ukujiya okuphezulu, okunciphisa ukushayisana kwezinhlayiya ze-colloidal kanye nokungcola emanzini, okuvimbela ukunamathelana kwe-flocculants. Ngakho-ke, naphezu kokwandisa umthamo we-flocculants, i-flocculation ihlala ihamba kancane, okuholela ezakhiweni ezikhululekile kanye nezinhlayiya ezincane okunzima ukuzisusa ngaphansi kwezimo zokushisa eziphansi.

Ithonya Lobukhulu Bezinhlayiya Zokungcola

Ubukhulu kanye nokusatshalaliswa kwezinhlayiya zokungcola emanzini angcolile nakho kuthinta kakhulu ukusebenza kahle kwe-flocculation. Ubukhulu bezinhlayiya ezingalingani noma ezincane kakhulu bungabangela ukusebenza kabi kwe-flocculation ngoba izinhlayiya ezincane zokungcola zivame ukuba nzima ukuzihlanganisa ngempumelelo ngokusebenzisa ama-flocculant. Ezimweni ezinjalo, i-reflux sedimentation noma ukungezwa kwenani elifanele le-flocculant kungathuthukisa ukusebenza kahle kwe-flocculation.

Ukukhethwa Kwezinhlobo Ze-Flocculant

Ukukhetha uhlobo olufanele lwe-flocculant kubalulekile ekuthuthukiseni ukusebenza kahle kokwelashwa kwamanzi amdaka. Izinhlobo ezahlukene ze-flocculants, njenge-flocculants ezingaphili, i-polymer flocculants, kanye ne-activated silica gel, zinezinzuzo zazo ezimweni ezahlukene. Isibonelo, lapho izinto eziqinile ezilenga emanzini amdaka zikhona ngesimo se-colloidal, i-flocculants ezingaphili zivame ukusebenza kangcono. Lapho kubhekene nokumiswa kwezinhlayiya ezincane, ukungezwa kwe-polymer flocculants noma i-activated silica gel njenge-coagulants kungadingeka. Ezimweni eziningi, ukusetshenziswa okuhlangene kwe-inorganic kanye ne-polymer flocculants kungathuthukisa kakhulu ukusebenza kwe-flocculation futhi kwandise ububanzi bokusetshenziswa.

Izinto ezifana nenani le-pH, i-alkalinity, izinga lokushisa, usayizi wezinhlayiya zokungcola, kanye nohlobo lwamanzi angcolile e-flocculant kuthinta ukusebenza kahle kwama-flocculant ekwelapheni amanzi angcolile. Ukuqonda okujulile nokulawula lezi zinto kubaluleke kakhulu ekuthuthukiseni ukusebenza kahle kokwelashwa kwamanzi angcolile. Singabaphakeli bakho abathembekile bamakhemikhali e-flocculant, anezinhlobo eziningi zama-flocculant, kufaka phakathi i-PAM, i-PAC, njll. Kuwebhusayithi yethu esemthethweni ungahlola kalula imikhiqizo yethu ehlukahlukene. Uma unemibuzo noma udinga usizo, sicela ukhululeke ukuxhumana nathi!
