Amanzi awumthombo wokuphila, asikwazi ukuphila ngaphandle kwamanzi, noma kunjalo, ngenxa yokuthuthukiswa kwabantu nokungcoliswa kwemithombo yamanzi, izindawo eziningi zibhekene nokuntuleka kwamanzi okukhulu kanye nokwehla kwezinga lamanzi. Ukuze kuxazululwe lezi zinkinga, ososayensi nonjiniyela abaningi bazinikela ocwaningweni nasekuthuthukisweni kobuchwepheshe bokuhlanza amanzi. Phakathi kwazo, i-Polyaluminium Chloride (PAC), njenge-ejenti ebalulekile yokwelapha amanzi, isetshenziswa kabanzi emkhakheni wokuhlanza amanzi nokuhlanza indle.
Umsebenzi
Isenzo se-PAC sifezwa ngezici ezine zebilayer ecindezelwe yomkhiqizo wayo noma we-hydrolysis, i-electrical neutralization, i-tape web trapping, kanye ne-adsorption bridging.
Iyashesha futhi ihlunge i-particle engenziwa i-oxidizer ibangele i-COD, ngaleyo ndlela yehlise i-COD, kanye nemvula ye-particle.PAC iwumkhiqizo ophephile, ohambisana nemvelo, futhi osebenzayo wokwelapha amanzi angcolile. Akukwazi nje ukunciphisa ngempumelelo ukuhlushwa kwezinto eziphilayo, amaminerali kanye nama-microorganisms endle, kodwa futhi kunganciphisa i-chromaticity kanye ne-turbidity yendle, kunciphise ngempumelelo ukungcola, kuthuthukise iphunga lendle, kunciphise i-acidity kanye ne-alkalinity yendle, ukuze kuthuthukiswe ngempumelelo ukungcoliswa kwendle. I-PAC iyisengezo esisebenzayo sokuhlanza indle, enendima ebalulekile ekuhlanzeni indle.
Izici
I-PAC iyi-inorganic polymer coagulant. Ingathunaza izinhlayiya ezinhle ezimisiwe ezimisiwe kanye nama-ion e-colloidal emanzini, i-aggregate, i-flocculate, i-coagulate futhi inemvula ngokucindezelwa kwe-double layer, i-adsorption kanye ne-neutralization kagesi, i-adsorption kanye ne-bridging, kanye nokubamba inetha eliphansi, njll, ukuze kuzuzwe ukuhlanzwa kanye nomunye umphumela we-PAC unomphumela obanzi wokwelashwa. uhla lwezinhlelo zokusebenza futhi uzivumelanise nohlu olubanzi lwamanzi.Kulula ukwakha imbali enkulu ye-alum ngokushesha futhi inokusebenza okuhle kwemvula. Inohlu olubanzi lwenani elifanele le-PH (5-9), futhi inani le-PH kanye ne-alkalinity yamanzi ahlanzekile kuncane. Uma izinga lokushisa lamanzi liphansi, lingakwazi ukugcina umphumela wemvula ozinzile. I-alkalinity yayo iphakeme kunezinye i-aluminium nosawoti wensimbi, futhi inomthelela omncane wokuguguleka kwemishini.
Isicelo
I-PAC iwuhlobo olusha lwe-macromolecule coagulant esebenza kahle kakhulu. Isetshenziswa kabanzi emanzini okuphuza, ukuhlanzwa kwamanzi ezimbonini, ukuthuthwa kwendle kamasipala okulahlwe yizimboni.Kungaholela ekwakhekeni okusheshayo komhlambi ngosayizi omkhulu kanye nemvula esheshayo. Inokuvumelana nezimo ezibanzi emanzini ngamazinga okushisa ahlukene kanye nokuncibilika okuhle. I-PAC yonala kancane futhi ilungele ukudoswa okuzenzakalelayo futhi ilungele ukusebenza.
Isiphetho
I-PAC iyi-coagulant ebalulekile emkhakheni wokuhlanza amanzi. Inomphumela wokuhlanza osebenzayo kumazinga okushisa aphansi, i-turbidity ephansi kanye namanzi aphezulu anodaka. Kodwa-ke, njengoba i-monomer yayo ihlangana ne-organic matter ukuze ikhiqize izinto eziyingozi empilweni yomuntu, kubalulekile ukuqinisekisa ukuhlanzeka kwe-PAC ekuhlanzeni amanzi.
