Amakhemikhali e-Polyacrylamide Molecular Water Treatment

I-Polyacrylamide (PAM) yitemu elivamile le-acrylamide homopolymer noma i-copolymerized namanye ama-monomers, futhi ingenye yezinhlobo ezisetshenziswa kakhulu zama-polymers ancibilika emanzini.Ngenxa yokuthi iyunithi yesakhiwo se-polyacrylamide iqukethe amaqembu e-amide, kulula ukwakha izibopho ze-hydrogen, okwenza kube nokuncibilika okuhle kwamanzi kanye nomsebenzi wamakhemikhali aphezulu, futhi kulula ukuthola ukuguqulwa okuhlukahlukene kwe-branched chain noma isakhiwo senethiwekhi ngokuxhunyelelwa noma ukuxhumanisa., Isetshenziswa kabanzi ekuhloleni i-petroleum, ukwelashwa kwamanzi, izindwangu, ukwenza amaphepha, ukucubungula amaminerali, imithi, ezolimo kanye nezinye izimboni, futhi yaziwa ngokuthi "izinsiza kuzo zonke izimboni".Izinkambu eziyinhloko zokufaka izicelo emazweni angaphandle ukuhlanzwa kwamanzi, ukwenza amaphepha, izimayini, i-metallurgy, njll.;eShayina, inani elikhulu kunawo wonke lisetshenziswa njengamanje emkhakheni wokukhipha uwoyela, kanti amasimu akhula ngokushesha asemasimini okuhlanza amanzi nokwenza amaphepha.

Inkambu yokuhlanza amanzi:

Ukuhlanza amanzi kuhlanganisa ukuhlanzwa kwamanzi aluhlaza, ukukhucululwa kwendle kanye nokuhlanza amanzi ezimbonini.Isetshenziswa ngokuhambisana nekhabhoni ecushiwe ekwelashweni kwamanzi aluhlaza, ingasetshenziselwa ukuhlangana nokucacisa izinhlayiya ezimisiwe emanzini asekhaya.Ukusetshenziswa kwe-organic flocculant acrylamide esikhundleni se-flocculant ye-inorganic kungandisa umthamo wokuhlanza amanzi ngaphezu kwama-20% ngisho nangaphandle kokuguqula ithangi lokuxazulula;ekulashwa kwendle, ukusetshenziswa kwe-polyacrylamide kungakhuphula izinga lokusebenzisa ukugaywa kabusha kwamanzi futhi kungasetshenziswa njenge-Sludge dewatering;esetshenziswa njenge-ejenti ebalulekile yokwakha ekuhlanzeni amanzi ezimbonini.Inkambu enkulu yokusetshenziswa kwe-polyacrylamide phesheya ukwelashwa kwamanzi, futhi isicelo kulo mkhakha e-China siyakhuthazwa.Indima eyinhloko ye-polyacrylamide ekwelashweni kwamanzi: [2]
(1) Yehlisa inani le-flocculant.Ngaphansi kwesisekelo sokufinyelela ikhwalithi yamanzi efanayo, i-polyacrylamide isetshenziswa njengosizo lwe-coagulant ngokuhambisana namanye ama-flocculants, anganciphisa kakhulu inani le-flocculant esetshenzisiwe;(2) Thuthukisa izinga lamanzi.Ekuphathweni kwamanzi okuphuza kanye nokwelashwa kwamanzi angcolile ezimbonini, ukusetshenziswa kwe-polyacrylamide ngokuhambisana ne-flocculants ye-inorganic kungathuthukisa kakhulu izinga lamanzi;(3) Khulisa amandla e-floc kanye nesivinini se-sedimentation.I-flocs eyakhiwe yi-polyacrylamide inamandla aphezulu nokusebenza kahle kwe-sedimentation, ngaleyo ndlela ikhulise isivinini sokuhlukanisa uketshezi oluqinile futhi lula ukuphelelwa amandla kwamanzi odaka;(4) I-anti-corrosion kanye ne-anti-scaling yesistimu yokupholisa ejikelezayo.Ukusetshenziswa kwe-polyacrylamide kunganciphisa kakhulu inani le-flocculants ye-inorganic, ngaleyo ndlela kugweme ukubekwa kwezinto ezingaphili ebusweni bemishini futhi kubambezele ukugqwala kanye nokukala kwemishini.

I-Polyacrylamide isetshenziswa kabanzi njengosizo lokugcina, usizo lokuhlunga, i-ejenti yokulinganisa, njll. emkhakheni wokwenza iphepha ukuze kuthuthukiswe ikhwalithi yephepha, ukusebenza kokuphelelwa amandla kwamanzi okudaka, izinga lokugcinwa kwemicu emihle kanye nama-fillers, ukunciphisa ukusetshenziswa kwempahla eluhlaza kanye nokungcoliswa kwemvelo, Isetshenziswa njenge-disperant to ngcono ukufana kwephepha.I-Polyacrylamide isetshenziswa kakhulu ezicini ezimbili embonini yephepha.Enye iwukukhuphula izinga lokugcinwa kwezithako zokugcwalisa nezimibalabala ukuze kuncishiswe ukulahleka kwezinto ezingavuthiwe kanye nokungcoliswa kwemvelo;enye iwukwandisa amandla ephepha.Ukwengeza i-polyacrylamide entweni yephepha kungakhuphula izinga lokugcinwa kwemicu emihle nezinhlayiya zokugcwalisa kunetha futhi kusheshise ukuphelelwa amanzi emzimbeni kwento yephepha.Indlela yokusebenza ye-polyacrylamide iwukuthi izinhlayiya eziku-slurry ziyagobhoza futhi zigcinwe endwangu yokuhlunga ngokungathathi hlangothi noma ukuhlanganisa.Ukwakheka kwama-flocs nakho kungenza amanzi aku-slurry ahlunge kalula, kunciphise ukulahleka kwemicu emanzini amhlophe, kunciphise ukungcoliswa kwemvelo, futhi kusize ukuthuthukisa ukusebenza kahle kwemishini yokuhlunga kanye ne-sedimentation.
