Imaphi ama-polymers asetshenziswa njenge-Flocculants?

Isigaba esibalulekile enqubweni yokuhlanza amanzi angcolile ukuhlangana kanye nokulungisa izinto eziqinile ezimisiwe, inqubo encike kakhulu kumakhemikhali abizwa ngokuthi ama-flocculants. Kulokhu, ama-polymer adlala indima ebalulekile, ngakho-ke i-PAM, i-polyamines.Le ndatshana izodingida into efanayo.ama-polymer flocculants, ukusetshenziswa kwama-polymers njengama-flocculants ekuhlanzeni amanzi angcolile, kanye nemisebenzi ngemuva kwawo.

Yiziphi izinhlobo ze-polymer flocculants ezisetshenziswa kakhulu?

Ama-polymer flocculants asetshenziswa kakhulu ahlanganisa ama-polymers e-cationic, ama-anionic polymers nama-polymers angenayo. Lawa ma-polymers angatholwa ngezindlela ezihlukene zokwenziwa futhi anezakhiwo ezihlukene ze-cationic kanye namagatsha. Ekusetshenzisweni okungokoqobo, kuyadingeka ukukhetha ama-polymer flocculants afanelekile ngokuya ngemibandela ethile yamanzi angcolile ukuze uthole umphumela wokwelapha ongcono kakhulu. I-PAM, i-polyDADMAC, isetshenziswa kabanzi ekwelashweni kwamanzi angcolile ezimbonini. I-Polyacrylamide iyi-flocculant esetshenziswa kakhulu emhlabeni. Lawa ma-polymers ancibilikayo emanzini angawokwenziwa futhi angakhelwa ngokwezifiso izinhlelo zokusebenza ezithile ngezisindo zamangqamuzana ahlukene, ama-viscosities, amadigri eshaja ahlukene, amafomu ahlukene njengezinhlayiya, ama-emulsions, njll. I-PolyDADMAC isetshenziswa kabanzi emanzini kampompi, ukugeleza kwamanzi aluhlaza, udaka. ukuphelelwa amanzi emzimbeni, imboni yamaphepha kanye nemboni yokunyathelisa nokudaya.

Ukusetshenziswa kwama-flocculants ekuhlanzeni amanzi angcolile

Umgomo oyinhloko wokuhlanza amanzi angcolile ukususa ukungcola okufana nezinto eziqinile ezimisiwe, izinto eziphilayo ezincibilikisiwe kanye nezinhlayiya ze-colloidal emanzini ukuze kuthuthukiswe ikhwalithi yamanzi. Kule nqubo, ama-flocculants adlala indima ebalulekile. Ngokusebenzisa ama-flocculant, izinhlayiya ezincane kanye nezinto ezixubile emanzini zingabangelwa ukunqwabelana zibe iziqhumane ezinkulu, ezingasuswa kalula ngokushibilika noma ukuhlungwa. Lokhu akukwazi nje ukuthuthukisa izinga lamanzi, kodwa futhi kuthuthukisa ukusebenza kahle kokwelashwa nokunciphisa izindleko zokwelashwa.

Kungani ama-Polymers ekwazi ukwenza ama-flocculants?

Ama-polymers angasetshenziswa njengama-flocculants ikakhulukazi ngenxa yesisindo samangqamuzana aphezulu kanye nesakhiwo esinamagatsha amaningi. Lezi zakhiwo zivumela i-polymer ukuthi ikwazi ukukhanga kangcono ku-particle, yakhe ama-flocs amakhulu angahlala ngokushesha. Ngaphezu kwalokho, ama-polymers angakwazi ukuqeda ukuxoshwa kwe-electrostatic phakathi kwezinhlayiya ngokusebenzisa i-neutralization ye-charge, okuvumela izinhlayiya ukuthi zisondele futhi zihlangane ndawonye.

Indlela yokusebenza yama-polymers ekwelashweni kwamanzi angcolile

Indlela yokusebenza yama-polymers njengama-flocculants ingahlukaniswa ngezinyathelo ezintathu: ukunethezeka kokushaja, ukugeleza kwamabhuloho kanye nokuthwebula inetha. Okokuqala, i-polymer iqeda ukuxoshwa kwe-electrostatic phakathi kwezinhlayiya ngokusebenzisa ukuchithwa kwe-charge, okuvumela izinhlayiya ukuba zisondele. I-polymer ihlanganisa izinhlayiya ndawonye ukuze zenze ama-flocs amakhulu ngokusebenzisa i-bridging flocculation. Ekugcineni, lezi zinhlanzi zibuye zihlanganiswe futhi zihlale emanzini ngokushanela amanetha.

Izinto ezithinta ukusebenza kahle kwamaPolymers ekwelapheni amanzi angcolile

Kunezici eziningi ezithinta ukusebenza kahle kokwelashwa kwe-polymer yamanzi angcolile, okuhlanganisa uhlobo lwe-polymer, umthamo, inani le-pH, izinga lokushisa, isivinini esishukumisayo, njll. Phakathi kwazo, uhlobo lwe-polymer nomthamo kungenye yezinto ezibaluleke kakhulu. Izinhlobo ezahlukene zama-polymers zinezindawo zokushaja ezihlukene kanye nokusabalalisa kwesisindo samangqamuzana, ngakho-ke kuyadingeka ukukhetha uhlobo olufanele lwe-polymer kanye nomthamo wamanzi angcolile ahlukene ukuze kuzuzwe umphumela wokwelapha ongcono kakhulu. Ngaphezu kwalokho, izici ezifana nenani le-pH, izinga lokushisa, kanye nesivinini esinyakazayo nakho kuzothinta ukusebenza kahle kokwelashwa, futhi izimo ezifanele zidinga ukunqunywa ngokuhlolwa.

Ama-polymers adlala indima ebalulekile njengama-flocculants ekuhlanzeni amanzi angcolile. Ukuqonda okujulile kwendlela yokusebenza kanye nezici ezithonyayo zama-polymers kunganikeza ukwesekwa okubalulekile kwethiyori kanye nesiqondiso esisebenzayo sokuthuthukisa izinqubo zokuhlanza amanzi angcolile kanye nokwenza ngcono ukusebenza kahle kokwelashwa. Ngokuzayo, ngokuthuthukiswa okuqhubekayo kwezidingo zokuvikelwa kwemvelo kanye nokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, kukholakala ukuthi ukusetshenziswa kwama-polymers ekuhlanzeni amanzi angcolile kuzoba okubanzi futhi okujulile.
