Ama-flocculant e-Polyacrylamide asebenza kahle kakhulu ekususeni amanzi odakeni nasekuhlalisweni kwendle. Amanye amakhasimende abika ukuthi i-polyacrylamide pam esetshenziswa ekususeni amanzi odakeni izobhekana nezinkinga ezinjalo nezinye. Namuhla, ngizohlaziya izinkinga eziningana ezivamile kuwo wonke umuntu.
1. Umphumela we-flocculation we-polyacrylamide awumuhle, futhi yisiphi isizathu sokuthi ungacindezelwa ungene odakeni? Uma umphumela we-flocculation ungemuhle, kumele siqale sisuse izinkinga zekhwalithi zomkhiqizo we-flocculant uqobo, ukuthi ngabe i-cationic polyacrylamide ihlangabezana nezindinganiso zesisindo sama-molecule e-ionic, kanye nomphumela wokukhipha amanzi odakeni womkhiqizo ongahlangabezani nezindinganiso Akulungile neze. Kulesi simo, ukufaka esikhundleni se-PAM ngezinga le-ion elifanele kungaxazulula inkinga.
2. Yini okufanele ngiyenze uma inani le-polyacrylamide likhulu kakhulu?
Inani elikhulu lisho ukuthi okuqukethwe kwenkomba yomkhiqizo akwanele, futhi kukhona igebe phakathi kwezinkomba ezidingekayo ze-polyacrylamide kanye ne-sludge flocculation. Ngalesi sikhathi, udinga ukukhetha uhlobo futhi, ukhethe imodeli ye-PAM efanele kanye nenani lokwengeza ukuze ulihlole, bese uthola izindleko zokusebenzisa ezingabizi kakhulu. Ngokuvamile, kunconywa ukuthi ukuhlushwa kwe-polyacrylamide okuncibilikisiwe kube yinkulungwane eyodwa kuya kwezinkulungwane ezimbili, futhi kwenziwa ukukhetha okuncane kokuhlola ngokwalokhu kuhlushwa, futhi imiphumela etholakele inengqondo kakhulu.
3. Yini okufanele ngiyenze uma i-viscosity ye-sludge ngemuva kokusebenzisa i-polyacrylamide ekususeni amanzi kwe-sludge iphezulu?
Lesi simo sibangelwa ukwengezwa ngokweqile kwe-polyacrylamide noma umkhiqizo kanye nodaka olungafanele. Uma i-viscosity yodaka incipha ngemva kokunciphisa inani lokwengeza, khona-ke kuyinkinga yenani lokwengeza. Uma inani lokwengeza lincishisiwe, umphumela awutholakali futhi udaka alukwazi ukucindezelwa, khona-ke kuyinkinga yokukhetha umkhiqizo.
4. I-Polyacrylamide ifakwa odakeni, futhi okuqukethwe kwamanzi kwekhekhe lodaka elilandelayo kuphakeme kakhulu, kufanele ngenzenjani uma ikhekhe lodaka lingomile ngokwanele?
Kulesi simo, qala uhlole imishini yokukhipha amanzi emzimbeni. Umshini webhande kufanele uhlole ukuthi ukwelulwa kwendwangu yokuhlunga akwanele, ukungena kwamanzi kwendwangu yokuhlunga nokuthi indwangu yokuhlunga idinga ukushintshwa; umshini wokucindezela isihlungi sepuleti nohlaka udinga ukuhlola ukuthi isikhathi sokucindezela isihlungi sanele yini, ukuthi ingcindezi yesihlungi iyafaneleka yini; i-centrifuge idinga ukuhlola ukuthi ukukhethwa kwe-ejenti yokukhipha amanzi emzimbeni kuyafaneleka yini. Imishini yokukhipha amanzi emzimbeni ehlanganisiwe igxile ekuhloleni ukuthi isisindo sama-molecule se-polyacrylamide siphezulu kakhulu, nokuthi imikhiqizo ene-viscosity ephezulu kakhulu ayivumeli udaka lucindezelwe!
Kusenezinkinga eziningi ezivamile ze-polyacrylamide ekususeni amanzi odakeni. Lezi ezingenhla ziyizinkinga nezixazululo ezivame kakhulu ezifingqiwe enanini elikhulu lokulungisa amaphutha endaweni. Uma unemibuzo mayelana nokucindezela noma ukuthuthwa kodaka lwe-cationic polyacrylamide, konke Ungasithumelela i-imeyili, ake sixoxe ngokusetshenziswa kwe-polyacrylamide ekususeni amanzi odakeni!
