Izindaba

I-Polyaluminium chloride (PAC) iyinhlanganisela ye-polymer ye-inorganic, futhi ukukhishwa kwayo kwe-fluoride kutholakala ikakhulukazi ngezindlela ezimbili ezilandelayo:

I-Chemisorption: I-PAC incibilike emanzini ikhiphe i-aluminium ion (Al³), futhi ihlanganiswe ne-fluoride ion (F) ukuze kwakheke i-hydrofluoric acid (HF) emaphakathi, bese yenza imvula engancibiliki i-aluminium fluoride (AlF ₃).

Umthelela we-co-precipitation: i-aluminium hydroxide colloid ekhiqizwe i-PAC hydrolysis imboza i-ion ye-fluorine yamahhala ngokusebenzisa i-adsorption ephezulu kanye nokuthwebula kwe-mesh, futhi ekugcineni iyisuse ngokuhlukana koketshezi oluqinile.

Izizathu zokwenyuka komthamo we-polyaluminium chloride (PAC) zingahlaziywa kusukela ezimeni zemvelo, izinguquko zekhwalithi yamanzi, izici ze-ejenti kanye nenqubo yokusebenza. Ulwazi lokusesha luhlelwe kanje:

Izinzuzo eziyinhloko zobuchwepheshe be-polymeric iron sulfate decolorization

I-Polyaluminium chloride (i-PAC, njenge-ejenti yokwelapha amanzi esebenza kahle kakhulu) isetshenziswa kabanzi ekuhlanzeni amanzi okuphuza, ukuhlanzwa kwamanzi angcolile ezimbonini neminye imikhakha. Nokho, njengomkhiqizo wamakhemikhali, iyagqwala futhi ingase ibangele izingozi zempilo. Leli phepha lihlanganisa izinkambiso zemboni kanye nezinyathelo eziphuthumayo, lifingqa ngokuhlelekile izindawo zayo zokusebenza zokuphepha ukuze kubhekiswe odokotela.

I-Polyaluminium Chloride (PAC), enefomula yamakhemikhali ethi Al2(OH)nCl6−nAl2 (OH)n.Cl6−nₘ, iyi-polymer coagulant esebenza kahle kakhulu ye-inorganic. Ikhiqizwe nge-hydrolysis kanye ne-polymerization kasawoti we-aluminium, i-PAC izidla ngamakhono aqinile okukhangisa, ukugeleza okusheshayo, kanye nokuvumelana nezimo kulo lonke ibanga le-pH. Isetshenziswa kabanzi ku-ukuhlanzwa kwamanzi okuphuza, ukuhlanzwa kwamanzi angcolile ezimbonini, ukuphathwa kwendle emadolobheni, nokunye.

Amanzi aphansi okushisa aphansi (izinga lokushisa

Amandla okususa i-fluoride e-polyaluminium chloride (PAC) atholakala ezicini zayo zamakhemikhali ezihlukile nendlela yokwenza, ikakhulukazi ehilela imigomo elandelayo:

Ngomongo wemithetho eqinile yezemvelo, izikhungo zokuhlanza indle zidinga ukufeza ukukhishwa okujwayelekile ngokuthuthukiswa kobuchwepheshe kanye nokuphatha kahle. Njenge-ejenti yokuhlanza amanzi ewumongo, ukukhetha okunengqondo nokusebenzisa kahle i-polyaluminium chloride (PAC) kubalulekile. Okulandelayo yizixazululo ezisekelwe kuzinqubomgomo zakamuva nezinqubo zemboni

Izinga lokushisa eliphansi kanye nokwelashwa kwamanzi angcolile aphansi kungenye yezinkinga zobuchwepheshe emkhakheni wokuhlanza amanzi.
