Izinto Ezithinta Ukusebenza Kwe-Flocculant Ekuhlanzeni kwamanzi angcolile

Ekwelashweni kwamanzi angcolile, i-pH iyisici esibalulekile esithonya ngqo ukusebenza kahle kweAma-Flocculants.Lesi sihloko sicubungula umthelela we-pH, i-alkalinity, izinga lokushisa, usayizi wezinhlayiyana zokungcola, kanye nohlobo lwe-flocculant ekusebenzeni kahle kwe-flocculation.

Umthelela we-pH

I-pH yamanzi angcolile ihlobene eduze nokukhetha, umthamo, kanye nokusebenza kahle kwe-coagulation-sedimentation kwama-flocculants.Ucwaningo lubonisa ukuthi uma i-pH ingaphansi kuka-4, ukusebenza kahle kwe-coagulation kuba kubi kakhulu.Lokhu kungase kube ngenxa ye-pH ephansi eqinisa izinhlayiya ze-colloidal emanzini angcolile, okwenza kube nzima ngama-flocculants ukuwahlanganisa ngokuphumelelayo.Uma i-pH iphakathi kuka-6.5 no-7.5, ukusebenza kahle kwe-coagulation kuba ngcono kakhulu ngoba ukungazinzi kwezinhlayiya ze-colloidal kulolu hlu lwe-pH kuthuthukisa ukusebenza kwama-flocculants.Kodwa-ke, lapho i-pH idlula u-8, ukusebenza kahle kwe-coagulation kwehla kakhulu, mhlawumbe ngenxa yokuthi i-pH ephezulu ishintsha ibhalansi ye-ion emanzini angcolile, kuthinte kabi ama-flocculants.

Uma i-pH iphansi kakhulu, i-PAC ayikwazi ukwenza ama-flocs ngokuphumelelayo, futhi amaqembu e-anionic we-APAM azosuswa, okulenze lingasebenzi.Uma i-pH iphezulu kakhulu, i-PAC imvula ngokushesha kakhulu, okuholela ekusebenzeni kabi, futhi i-CPAM ithambekele ekungeneni kwe-hydrolysis futhi ingasebenzi.

Indima ye-Alkalinity

I-alkalinity ye-sewage buffers i-pH.Uma i-alkalinity yendle inganele, ngokuvamile kuyadingeka ukuthi ingezelelwe ngamakhemikhali afana ne-lime ukuze kugcinwe ukuzinza kwe-pH okuthuthukisa umphumela we-PAC we-flocculation ongcono kakhulu.Ngokuphambene, lapho i-pH yamanzi iphezulu kakhulu, ama-asidi angase adinge ukungezwa ukuze kwehliswe i-pH ukuze ingathathi hlangothi, kuqinisekiswe ukusebenza kahle kwama-flocculants.

Umthelela Wezinga Lokushisa

Izinga lokushisa lamanzi angcolile liphinde libe yisici esibalulekile esithonya ukusebenza kahle kwe-flocculation.Emazingeni okushisa aphansi, amanzi angcolile abonisa i-viscosity ephezulu, enciphisa imvamisa yokushayisana phakathi kwezinhlayiya ze-colloidal nokungcola emanzini, okuvimbela ukunamathelana okuhlangene kwama-flocculants.Ngakho-ke, naphezu kokwandisa umthamo we-flocculants, i-flocculation ihlala ihamba kancane, okuholela ekwakhiweni okuxekethile kanye nezinhlayiya ezinhle okunzima ukuzisusa ngaphansi kwezimo eziphansi zokushisa.

Umthelela Wosayizi Wezinhlayiyana Zokungcola

Ubukhulu nokusatshalaliswa kwezinhlayiya zokungcola emanzini angcolile nakho kuthinta kakhulu ukusebenza kahle kwe-flocculation.Usayizi wezinhlayiya ezingalingani noma ezincane ngokweqile zingase zibangele ukusebenza kabi kokugeleza ngoba izinhlayiya ezincane zokungcola ngokuvamile kunzima ukuzihlanganisa ngempumelelo ngokusebenzisa ama-flocculants.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 angcolile.Izinhlobo ezahlukahlukene zama-flocculants, njengama-inorganic flocculants, ama-polymer flocculants, nejeli ye-silica ecushiwe, zinezinzuzo zazo ezimeni ezihlukene.Isibonelo, lapho okuqinile okumisiwe emanzini angcolile kukhona ngesimo se-colloidal, ama-inorganic flocculants ngokuvamile asebenza kangcono.Lapho usebenzisana nokumiswa kwezinhlayiyana ezincane, ukungezwa kwe-polymer flocculants noma ijeli ye-silica ecushiwe njengama-coagulants kungase kudingeke.Ezimweni eziningi, ukusetshenziswa okuhlangene kwe-inorganic kanye ne-polymer flocculants kungathuthukisa kakhulu ukusebenza kahle kwe-flocculation futhi kwandise ububanzi bokusebenza.

Izinto ezifana nenani le-pH, i-alkalinity, izinga lokushisa, usayizi wezinhlayiyana zokungcola, nohlobo lwe-flocculant lwamanzi angcolile ngokuhlanganyela kuthinta ukusebenza kahle kwama-flocculants ekuhlanzeni amanzi angcolile.Ukuqonda okujulile nokulawulwa kwalezi zici kubaluleke kakhulu ekwenzeni ngcono ukusebenza kahle kokuhlanza amanzi angcolile.Singabahlinzeki bakho abathembekile bamakhemikhali e-flocculant, anezinhlobo eziningi ze-flocculants, okuhlanganisa i-PAM, i-PAC, njll.
