Iyini i-Ferric Chloride esetshenziselwa ukwelashwa kwamanzi?

I-Ferric Chlorideiyinhlanganisela yamakhemikhali enefomula ethi FeCl3. Isetshenziswa kabanzi ezinkambisweni zokwelashwa kwamanzi njenge-coagulant ngenxa yokuphumelela kwayo ekukhipheni ukungcola nokungcola emanzini futhi ngokuvamile isebenza kangcono emanzini abandayo kune-alum. Cishe u-93% we-ferric chloride usetshenziswa ekuhlanzeni amanzi, okungukuthi, amanzi angcolile, indle, amanzi okupheka kanye namanzi okuphuza. I-Ferric chloride isetshenziswa kakhulu esimweni esiqinile njengesixazululo sokuhlanza amanzi kanye namanzi angcolile.

Ukusetshenziswa kwe-ferric chloride ekwelapheni amanzi:

1. I-Coagulation kanye ne-Flocculation: Enye yezindlela eziyinhloko ezisetshenziswa ngayo i-ferric chloride ekuhlanzeni amanzi ifana ne-coagulant. Uma yengezwa emanzini, i-ferric chloride iphendulana namanzi ukuze ikhiqize i-ferric hydroxide futhi i-adsorbs yakamuva izinhlayiya ezimisiwe, i-organic matter, nokunye ukungcola ukuze kwakhe izinhlayiya ezinkulu, ezisinda kakhulu ezibizwa ngokuthi ama-flocs. Lezi zinhlayiya zingase zizinze kalula ngesikhathi sedimentation noma izinqubo zokuhlunga, okuvumela ukukhishwa kokungcola emanzini.

2. Ukususwa kwe-Phosphorus: I-ferric chloride iphumelela kakhulu ekukhipheni i-phosphorus emanzini. I-Phosphorus iyisakhi esivamile esitholakala emanzini angcolile, futhi amazinga amaningi angaholela eutrophication ekutholeni imizimba yamanzi. I-Ferric chloride yakha izakhi ezingancibiliki nge-phosphorus, ezingase zisuswe ngemvula noma ngokuhlunga, okusiza ukunciphisa amazinga e-phosphorus emanzini.

3. Ukususwa Kwensimbi Enzima: I-ferric chloride iphinde isetshenziselwe ukususa izinsimbi ezisindayo, njenge-arsenic, i-lead, ne-mercury, emanzini. Lezi zinsimbi zingaba nobuthi obukhulu futhi zibe yingozi enkulu empilweni uma zikhona emanzini okuphuza. I-Ferric chloride yakha i-insoluble metal hydroxides noma i-oxychlorides yensimbi, engabese isuswa ngezinqubo zokuna kwemvula noma zokuhlunga, ngokuphumelelayo kunciphise ukugcwala kwezinsimbi ezisindayo emanzini.

4. Ukususa Umbala Nephunga: I-Ferric chloride iyasebenza ekususeni izinhlanganisela ezibangela iphunga emanzini. I-oxidizes izakhi ze-organic ezibhekene nombala nephunga, zihlukanise zibe yizinto ezincane, ezingamukeleki kakhulu. Le nqubo isiza ukuthuthukisa ikhwalithi yobuhle yamanzi, iwenze afaneleke kakhulu ukuphuza, izinjongo zezimboni, noma zokungcebeleka.

5. Ukulungiswa kwe-pH: Ngokulawula i-pH, i-ferric chloride ingathuthukisa ukusebenza kwezinye izinqubo zokwelapha, ezifana ne-coagulation, i-flocculation, kanye nokubulala amagciwane. Ibanga le-pH elikahle lingasiza ekudaleni izimo ezifanele zokukhishwa kokungcola nokungcola emanzini.

6. Ukulawulwa Kwe-Disinfection Byproduct: I-Ferric chloride ingasiza ukulawula ukwakheka kwe-disinfection byproducts (DBPs) ngesikhathi sokwelashwa kwamanzi. Uma isetshenziswa kanye nezibulala-magciwane ezifana ne-chlorine, i-ferric chloride inganciphisa ukwakheka kwama-DBP afana ne-trihalomethanes (THMs) nama-haloacetic acid (HAAs), okungaba umdlavuza. Lokhu kuthuthukisa ukuphepha okuphelele kanye nekhwalithi yamanzi okuphuza.

7. I-Sludge Dewatering: I-Ferric chloride iphinde isetshenziswe ezinqubweni zokuqeda udaka ezindaweni zokuhlanza amanzi angcolile. Kuyasiza ukulungisa udaka ngokukhuthaza ukwakheka kwama-flocs amakhulu, aminyene, ezinza ngokushesha futhi akhulule amanzi ngokuphumelelayo. Lokhu kubangela ukusebenza okuthuthukisiwe kokukhipha amanzi kanye nokuncipha kwevolumu yodaka, okwenza kube lula futhi kungabizi kakhulu ukuphatha nokulahla udaka.

I-Ferric Chloride idlala indima ebalulekile ezicini ezehlukene zokwelashwa kwamanzi, okuhlanganisa ukujiya, ukususwa kwe-phosphorus nokususwa kwensimbi esindayo, ukususwa kombala nephunga, ukulungiswa kwe-pH, ukulawulwa komkhiqizo wokubulala amagciwane, kanye nokukhipha amanzi ngodaka. Ukuguquguquka nokusebenza kwayo kuyenza ibe yikhemikhali ebalulekile ekwelapheni kokubili amanzi okuphuza namanzi angcolile, okusiza ekuqinisekiseni ukuphepha, ikhwalithi, nokusimama kwemithombo yamanzi.
