Ama-flocculants e-Polyacrylamide asebenza kahle kakhulu ekususeni udaka kanye nokulungisa indle. Amanye amakhasimende abika ukuthi i-polyacrylamide pam esetshenziswa ekukhipheni amanzi ngodaka izohlangabezana nezinkinga ezinjalo nezinye. Namuhla, ngizohlaziya izinkinga ezimbalwa ezivamile zawo wonke umuntu. :
1. Umphumela we-flocculation we-polyacrylamide awumuhle, futhi yisiphi isizathu sokuthi kungani ungacindezelwa odaka? Uma umphumela we-flocculation ungemuhle, kufanele siqale sisuse izinkinga zekhwalithi yomkhiqizo we-flocculant ngokwawo, kungakhathaliseki ukuthi i-cationic polyacrylamide ihlangabezana ne-ionic molecular weight standard, kanye nomphumela wokuqeda amanzi ngodaka lomkhiqizo ongahlangabezani nendinganiso Akukuhle neze. . Kulokhu, ukufaka esikhundleni se-PAM ngeleveli ye-ion efanelekile 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 ozolihlola, futhi uthole ukusetshenziswa okuyongayo okwengeziwe. izindleko. Ngokuvamile, kunconywa ukuthi ukuhlushwa okuncibilikisiwe kwe-polyacrylamide kuyingxenye yenkulungwane kuya kwezinkulungwane ezimbili, futhi ukukhetha okuncane kokuhlola kwenziwa ngokwalokhu kuhlushwa, futhi imiphumela etholiwe inengqondo.
3.Yini okufanele ngiyenze uma i-viscosity ye-sludge ngemva kokusebenzisa i-polyacrylamide ku-sludge dewatering iphezulu?
Lesi simo sibangelwa ukwengezwa ngokweqile kwe-polyacrylamide noma umkhiqizo ongafanele nodaka. Uma i-viscosity ye-sludge iyancipha ngemva kokunciphisa inani elingeziwe, khona-ke kuyinkinga yenani lokwengeza. Uma inani lokwengeza lincishisiwe, umphumela awutholakali futhi i-sludge ayikwazi ukucindezelwa, khona-ke kuyinkinga yokukhethwa komkhiqizo.
4. I-Polyacrylamide yengezwe ku-sludge, futhi okuqukethwe kwamanzi kwekhekhe lodaka elilandelayo kuphezulu kakhulu, yini okufanele ngiyenze uma ikhekhe lodaka lingamile ngokwanele?
Kulokhu, qala uhlole imishini yokukhipha amanzi emzimbeni. Umshini webhande kufanele uhlole ukuthi ukunwetshwa kwendwangu yokuhlunga akwanele, ukungena kwamanzi kwendwangu yokuhlunga kanye nokuthi indwangu yokuhlunga idinga ukushintshwa; umshini wokuhlunga wepuleti kanye nohlaka udinga ukuhlola ukuthi isikhathi sokucindezela isihlungi sanele yini, Ukuthi ukucindezela kwesihlungi kufanelekile yini; i-centrifuge idinga ukuhlola ukuthi ukukhethwa kwe-ejenti yokuqeda amanzi emzimbeni kufanelekile. Isikulufu esistakiwe kanye nemishini yokukhipha amanzi emzimbeni igxile ekuhloleni ukuthi isisindo samangqamuzana e-polyacrylamide siphezulu kakhulu, futhi imikhiqizo ene-viscosity ephezulu kakhulu ayihambisani nodaka olucindezelayo!
Kusenezinkinga eziningi ezijwayelekile ze-polyacrylamide ekukhipheni amanzi ngodaka. Okungenhla yizinkinga ezivame kakhulu nezisombululo ezifingqiwe ngenani elikhulu lokulungisa amaphutha esizeni. Uma unemibuzo mayelana cationic Polyacrylamide sludge ngokucindezela noma sedimentation, konke Ungathumela i-imeyili kithi, ake sixoxe ukusetshenziswa polyacrylamide in sludge dewatering!
