Kunezinhlobo eziningi ze-flocculants, ezingahlukaniswa izigaba ezimbili, eyodwa yi-inorganic flocculants kanti enye ingu-organic flocculants.
(1) I-Inorganic Flocculants: Kubandakanya izinhlobo ezimbili zikasawoti wensimbi, usawoti wensimbi kanye nosawoti we-aluminium, kanye ne-inorganic polymer flocculants efanapolyaluminum chloride. Okusetshenziswayo okuvame ukusetshenziswa yilezi: I-Ferric Chloride, i-sulfate ye-Ferrous, i-Ferric sulfate, i-aluminium sulfate (alum), eyisisekelo aluminium chloride, njll.
(2) Ama-Organic Flocculants: Kakhulu izinto ze-polymer ezifana ne-polylamide. Ngoba ama-polymer flocculants anezinzuzo ze: umthamo omncane, izinga elisheshayo le-sedimentation, amandla aphezulu we-Floc, kanye nekhono lokukhulisa ama-Filtration Speed, umphumela wawo we-Floccation unamathuba amaningi ama-Inorgation, ngakho-ke njengamanje asetshenziswa kakhulu kumaphrojekthi wokwelashwa kwamanzi.
(Umsunguli we-ejenti yokwelashwa kwamanzi ochwepheshe - Umhlaba Ohlanzekile Wokuhlanza Amanzi)
I-Polymer Flocculontant - Polyyamide
Impahla ebalulekile eluhlaza yeI-PolyAcrylamide (Pam Forfut)i-acrylonitrile. Ihlanganiswa namanzi ngendlela ethile futhi itholwe nge-hydration, ukuhlanzwa, i-polymerization, ukomisa nezinye izinqubo.
Iziphetho ezilandelayo zingadonswa ekuhlolweni kwangaphambilini:
.
(2) I-Cationic Pam ilungele udaba olumisiwe ngecala elibi futhi liqukethe izinto eziphilayo.

Ukulungiswa kwe-Flocculont
I-Flocculant ingaba yisigaba esiqinile noma isigaba esiphakeme sokuhlushwa. Uma le flocculant ingezwe ngokuqondile ekumisweni, ngenxa yobuningi bayo obuphakeme kanye nezinga eliphansi lokuphazamiseka, i-flocculant ayikwazi ukuhlakazeka kahle ekumisweni, okuholela engxenyeni ye-flocculant ayikwazi ukudlala indima ye-flocculant. Ngakho-ke, ukuhlanganiswa okuqediwe kuyadingeka ukuvusa i-flocculant kanye nenani elifanele lamanzi ukufinyelela okuhlushwa okuthile, ngokuvamile kungabi ngaphezu kwe-4 ~ 5g / l, futhi kwesinye isikhathi kungaphansi kwaleli nani. Ngemuva kokuvusa ngokulinganayo, ingasetshenziswa. Isikhathi esivusa ama-1 ~ 2h.
Ngemuva kokuthi i-polymer flocculant ilungiswe, isikhathi sayo sokuqiniseka ngu-2 ~ 3D. Lapho isixazululo siba mhlophe esimhlophe, kusho ukuthi ikhambi liye liwohlokile futhi liphelelwe yisikhathi, futhi kufanele limiswe ngokushesha.
Iqembu lamide le-polyyamide elikhiqizwa yi-yixing Cleanwater Chemicals Co, Ltd. Ama-polycalide aphezulu we-molecular amafomu ama-polyges phakathi kwama-adsorbed ion, akhiqize ama-flocs, asheshise ukuqunjelwa kwezinhlayiya, ngaleyo ndlela athole umgomo wokugcina wokuhlukaniswa okuqinile okuqinile. Kunezinhlobo ze-anionic, ze-cationic nezona ezingezona ze-ionic. Ngasikhathi sinye, amakhasimende angenza ngokwezifiso imikhiqizo yezincazelo ezihlukile
Nesitatimende: Sigcina isimo sokungathathi hlangothi maqondana nemibono esihlokweni. Le ndatshana ingesenkolelo-ndlela kuphela, ukusetshenziswa kwezokuxhumana, hhayi ukusetshenziswa kwezentengiso, futhi ilungelo lobunikazi lingelombhali wokuqala. Ngiyabonga ngokunaka nokusekelwa kwakho!
