Isetyenziselwa ntoni iFerric Chloride kunyango lwamanzi?

I-Ferric Chlorideyikhompawundi yemichiza enefomula ethi FeCl3. Isetyenziswe ngokubanzi kwiinkqubo zokunyanga kwamanzi njenge-coagulant ngenxa yokusebenza kwayo ekususeni ukungcola kunye nokungcola emanzini kwaye ngokuqhelekileyo isebenza kakuhle emanzini abandayo kune-alum. Malunga ne-93% ye-ferric chloride isetyenziselwa ukucocwa kwamanzi, oko kukuthi, amanzi amdaka, ugutyulo, amanzi okupheka kunye namanzi okusela. I-Ferric chloride isetyenziswa ikakhulu kwifomu eqinileyo njengesisombululo samanzi kunye nokucocwa kwamanzi amdaka.

Ukusetyenziswa kwe-ferric chloride kunyango lwamanzi:

1. I-Coagulation kunye ne-Flocculation: Enye yezinto eziphambili zokusetyenziswa kwe-ferric chloride kunyango lwamanzi njenge-coagulant. Xa ifakwe emanzini, i-ferric chloride isabela emanzini ukuvelisa i-ferric hydroxide kunye ne-adsorbs yokugqibela i-particle emisiwe, i-organic matter, kunye nobunye ukungcola ukwenza amasuntswana amakhulu, anzima kakhulu abizwa ngokuba yi-flocs. Ezi flocs zinokuzinza ngokulula ngakumbi ngexesha lentlenga okanye iinkqubo zokuhluza, ezivumela ukukhutshwa kobumdaka emanzini.

2. Ukususwa kwe-Phosphorus: I-Ferric chloride isebenza ngokukodwa ekususeni i-phosphorus emanzini. I-Phosphorus sisondlo esiqhelekileyo esifumaneka kumanzi amdaka, kwaye amanqanaba angaphezulu angakhokelela kwi-eutrophication ekufumaneni imizimba yamanzi. I-Ferric chloride yenza ii-complexes ezingenayo i-insoluble kunye ne-phosphorus, ezinokuthi zisuswe emva kwemvula okanye i-filtration, inceda ukunciphisa amanqanaba e-phosphorus emanzini.

3. Ukususwa kwesinyithi esinzima: I-Ferric chloride isetyenziselwa ukususa isinyithi esinzima, njenge-arsenic, i-lead, kunye ne-mercury, emanzini. Ezi zinyithi zinokuba yingozi kakhulu kwaye zibeke imingcipheko enkulu yempilo ukuba zikhona emanzini okusela. I-Ferric chloride yenza i-insoluble metal hydroxides okanye i-oxychlorides yesinyithi, enokususwa emva kwemvula okanye iinkqubo zokucoca, ngokufanelekileyo ukunciphisa ukuxinwa kweentsimbi ezinzima emanzini.

4. Ukususwa koMbala kunye ne-Odor: I-Ferric chloride iyasebenza ekususeni imibala kunye ne-odor-casing compounds emanzini. I-oxidizes iikhompawundi ze-organic ezinoxanduva lombala kunye nevumba, ziqhekeke zibe zizinto ezincinci, ezingathandekiyo. Le nkqubo inceda ekuphuculeni umgangatho wobuhle bamanzi, iwenza afaneleke ngakumbi ukusela, ushishino, okanye iinjongo zokuzonwabisa.

5. Ukulungiswa kwe-pH: Ngokulawula i-pH, i-ferric chloride inokuphucula ukusebenza kwezinye iinkqubo zonyango, ezifana ne-coagulation, i-flocculation, kunye ne-disinfection. Uluhlu lwe-pH olufanelekileyo lunokunceda ukudala iimeko ezifanelekileyo zokususa ukungcola kunye nokungcola emanzini.

6. I-Disinfection Byproduct Control: I-Ferric chloride inokunceda ukulawula ukubunjwa kwe-disinfection byproducts (DBPs) ngexesha lokunyanga kwamanzi. Xa isetyenziswe kunye ne-disinfectants efana ne-chlorine, i-chloride ye-ferric inokunciphisa ukubunjwa kwe-DBPs ezifana ne-trihalomethanes (THMs) kunye ne-haloacetic acids (HAAs), ezinokuthi zibe ne-carcinogens. Oku kuphucula ukhuseleko jikelele kunye nomgangatho wamanzi okusela.

7. I-Sludge Dewatering: I-Ferric chloride iphinda isetyenziswe kwiinkqubo zokukhupha amanzi amdaka kwiindawo zokucocwa kwamanzi amdaka. Inceda ukulungelelanisa i-sludge ngokukhuthaza ukubunjwa kwee-flocs ezinkulu, ezixineneyo, ezihlala ngokukhawuleza kwaye zikhulule amanzi ngokufanelekileyo. Oku kubangela ukuphuculwa kokusebenza kwamanzi kunye nokunciphisa umthamo we-sludge, okwenza kube lula kunye neendleko ezisebenzayo ukuphatha nokulahla i-sludge.

I-Ferric Chloride idlala indima ebalulekileyo kwimiba eyahlukeneyo yonyango lwamanzi, kubandakanywa ukujiya, i-phosphorus kunye nokususwa kwesinyithi esinzima, ukususwa kombala kunye nevumba, ukulungiswa kwe-pH, ukulawulwa kwe-disinfection byproduct, kunye nokukhupha amanzi. Ukuguquguquka kwayo kunye nokusebenza kwayo kuyenza ibe yikhemikhali exabisekileyo kunyango lwamanzi okusela kunye namanzi amdaka, inceda ekuqinisekiseni ukhuseleko, umgangatho kunye nokuzinza kwemithombo yamanzi.
