Ungawengeza kanjani uPam

I-PolyAcrylamide (Pam) iyi-polymer eqondile ene-floccation, adhesion, ukuncishiswa kokuhudula, nezinye izakhiwo. Njenge-I-Polymer Organic Flocculont, kusetshenziswa kabanzi emkhakheni wekwelashwa kwamanzi. Lapho usebenzisa uPam, kufanele kulandelwe izindlela ezifanele zokusebenza ukuze zigweme ukungcola kwamakhemikhali.

Inqubo yokufaka i-PAM

IngomanePam eqinile, kudinga ukungezwa emanzini ngemuva kokuchithwa. Ngezimfanelo zamanzi ezahlukahlukene, izinhlobo ezahlukahlukene zePam zidinga ukukhethwa, futhi izixazululo zihlukaniswe ekugxileni okuhlukile. Lapho ungeza ama-polyyacrylamide, kufanele unakekele amaphuzu alandelayo:

Ukuhlolwa kwe-jar:Nquma ukucaciswa okuhle kanye nomthamo ngokuhlolwa kwe-jar. Esivivinyweni se-jar, kancane kancane kwandise umthamo we-polylamide, ubheke ukusebenza kwe-floccation, bese unquma umthamo ofanele.

Ilungiselela isisombululo se-pam samanzi:Kusukela i-anionic pam (i-apam) ne-nonion pam (NPAM) inesisindo esiphakeme samangqamuzana namandla anamandla, i-anionic polylamide ivame ukwakhiwa esikhaleni esinamanzi (okubhekisele kokuqukethwe okuqinile) kanye namanzi angathathi hlangothi ahlanzekile. Khetha i-aluminium enobuhlakani, noma amabhakede epulasitiki esikhundleni seziqukathi zensimbi njengoba i-iron ion ihlekisa ukuwohloka kwamakhemikhali kwalo lonke uPam. Ngesikhathi sokulungiselela, ama-polylacrylamide adinga ukufakwa afakwe emanzini ashukumisayo futhi afudumele ngokufanele (<60 ° C) ukusheshisa ukuncishiswa. Lapho kuchithwa, ukunakwa kufanele kukhokhwe ukufaka umkhiqizo ngokulinganayo futhi kancane kancane ungene ekunciphiseni ngezinyathelo ezivusa izinyathelo zokushisa nokushisa ukuze uvikele ukuqina. Isixazululo kufanele silungiselelwe endaweni yokushisa efanelekile, futhi ukugunda isikhathi eside nokuqinile kufanele kugwenywe. Kunconywe ukuthi umhlanganisi ujikeleze ngo-60-200 RPM; Ngaphandle kwalokho, kuzodala ukucekelwa phansi kwe-polymer futhi kuthinte umphumela wokusetshenziswa. Qaphela ukuthi isixazululo se-pam esinamanzi kufanele silungiselelwe ngokushesha ngaphambi kokusetshenziswa. Isitoreji sesikhathi eside sizoholela ekunciphiseni kancane kancane ekusebenzeni. Ngemuva kokungeza ikhambi lamanzi le-flecculant lokumiswa, ukushukumisa okunamandla isikhathi eside kuzobhubhisa ama-flocs akhiwe.

Izidingo ze-DOSIGH:Sebenzisa idivaysi ye-dosing ukwengeza uPam. Esesigabeni sokuqala sokusabela kokungeza uPam, kuyadingeka ukwandisa amathuba okuxhumana phakathi kwamakhemikhali namanzi okuphathwe ngangokunokwenzeka, andise ukuvuselisa, noma ukukhulisa izinga lokugeleza.

Izinto okufanele uphawule lapho ungeza uPam

Isikhathi sokuchithwa:Izinhlobo ezahlukene zePam zinezikhathi ezahlukahlukene zokuchithwa. I-Cationic Pam inesikhathi esifushane sokuqothula, kanti u-Anionic no-Anion Pam abanesikhathi eside sokuqothula. Ukukhetha isikhathi esifanele sokuqothula kungasiza ukuthuthukisa umphumela wokufukula.

Umthamo kanye nokuhlushwa:Umthamo ofanele uyisihluthulelo sokuthola umphumela omuhle kakhulu we-floccation. Umthamo owedlulele ungadala ukugibela ngokweqile kwama-colloids kanye nezinhlayiya ezimisiwe, zakha ama-seddiment amaningi esikhundleni sama-flocs, ngaleyo ndlela athinta ikhwalithi ye-affaent.

Imibandela yokuxuba:Ukuqinisekisa ukuxutshwa okwanele kwama-pam namanzi amdaka, imishini yokuxuba efanelekile nezindlela ezidinga ukukhethwa. Ukuxuba okungalingani kungahle kuholele ekuqothulweni okungaphelele kwe-pam, ngaleyo ndlela kuthinte umphumela wayo we-floccution.

Izimo zezemvelo zamanzi:Izici zezemvelo ezifana nenani le-PH, izinga lokushisa, ingcindezi, njll., Kuzothinta nomphumela we-Floccution kaPam. Ngokuya ngezimo ezisezingeni eliphakeme kwamanzi, la mapharamitha angadinga ukulungiswa kwemiphumela efanelekile.

Ukulandelana kwe-dosing:Ohlelweni lwe-deg-alent dosing, kubalulekile ukuqonda ukulandelana kwe-dosing kwama-ejenti ahlukahlukene. Ukulandelana kwe-dosing okungalungile kungathinta ukuxhumana phakathi kwe-pam nama-colloids nezinhlayiya ezimisiwe, ngaleyo ndlela kuthinte umphumela wokufakelwa.

Polycrylamide(UPam) uyi-polymer eguquguqukayo enezicelo ezahlukahlukene, ikakhulukazi ekwelashweni kwamanzi. Ukwandisa ukusebenza kwayo futhi ugweme ukuchitheka, kubalulekile ukulandela izinqubo zokusebenza ezifanele. Ngokucabanga ngokucophelela izinto ezinjengesikhathi sokuchithwa, umthamo, izimo zokuxuba, izimo zemvelo zamanzi, nokulandelana kwe-dosing, ungasebenzisa ngempumelelo uPam ukuze uzuze imiphumela yamanzi.
