Amanzi angumthombo wokuphila, asikwazi ukuphila ngaphandle kwamanzi, noma kunjalo, ngenxa yokuthuthukiswa kwabantu nokungcoliswa kwemithombo yamanzi, izindawo eziningi zibhekene nokushoda 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 yokuhlanza amanzi, isetshenziswa kabanzi emkhakheni wokuhlanza amanzi nokuhlanza indle.
Umsebenzi
Isenzo se-PAC sifezwa ngezici ezine zebilayer ecindezelwe yomkhiqizo wayo noma we-hydrolysis, ukungathathi hlangothi kukagesi, 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.Ngeke nje kunciphise ngempumelelo ukugcwala kwezinto eziphilayo, amaminerali kanye nama-microorganisms kundle, kodwa futhi kunganciphisa i-chromaticity kanye ne-turbidity yendle, kunciphise ngempumelelo ukungcola, kuthuthukise iphunga lendle, kunciphise i-acidity kanye ne-alkalinity yendle, ukuze ukwenza ngcono 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 kanye nemvula ngokucindezelwa kwe-double layer, i-adsorption kanye ne-neutralization kagesi, i-adsorption kanye ne-bridging, kanye nokudonsa inetha, njll, ukuze kuzuzwe ukuhlanzwa nomphumela wokwelapha. Uma iqhathaniswa namanye ama-coagulant, i-PAC inezinzuzo ezilandelayo: Inezinhlobonhlobo zokusetshenziswa futhi ivumelane nenhlobonhlobo yamanzi.Kulula ukwenza imbali enkulu ye-alum ngokushesha futhi ibe nokusebenza kahle 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 inomphumela omncane wokuguguleka kwempahla.
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.
