Kunezinhlobo eziningi ze-flocculants, ezingahlukaniswa zibe izigaba ezimbili, enye i-inorganic flocculants kanti enye i-organic flocculants.
(1) I-Inorganic flocculants: kufaka phakathi izinhlobo ezimbili zikasawoti wensimbi, usawoti wensimbi nosawoti we-aluminium, kanye nama-polymer flocculants angaphili afanai-polyaluminium chloride. Okuvame ukusetshenziswa yilezi: i-ferric chloride, i-ferrous sulfate, i-ferric sulfate, i-aluminium sulfate (i-alum), i-aluminium chloride eyisisekelo, njll.
(2) Ama-flocculants e-Organic: ikakhulukazi izinto ze-polymer ezifana ne-polyacrylamide. Ngenxa yokuthi ama-polymer flocculants anezinzuzo zokuthi: umthamo omncane, izinga lokushesha kwenhlabathi, amandla e-floc aphezulu, namandla okwandisa isivinini sokuhluza, umphumela wawo wokugeleza uphindwe izikhathi eziningana kuya kwezingamashumi amaningi kunalowo we-inorganic flocculants, ngakho-ke okwamanje isetshenziswa kabanzi. ezinhlelweni zokuhlanza amanzi.
(Umkhiqizi we-ejenti yokuhlanza amanzi ochwepheshe-Izwe elihlanzekile Amanzi)
I-polymer flocculant - i-polyacrylamide
Impahla eluhlaza eyinhloko yei-polyacrylamide (i-PAM ngamafuphi)i-acrylonitrile. Ihlanganiswe namanzi ngesilinganiso esithile futhi itholakala ngokusebenzisa i-hydration, ukuhlanzwa, i-polymerization, ukomisa nezinye izinqubo.
Iziphetho ezilandelayo zingafinyelelwa ekuhloleni kwangaphambilini:
(1) I-Anionic PAM ifaneleka odabeni olumisiwe olungaphili olunokugxila okuphezulu nokushajwa okuhle, kanye nezinhlayiya ezimahhadla ezimisiwe (0.01~1mm), kanye nevelu ye-pH ephakathi nendawo noma ene-alkali.
(2) I-Cationic PAM ifaneleka odabeni olumisiwe olunegethivu futhi equkethe izinto eziphilayo.
(3) I-Nonionic PAM ilungele ukuhlukaniswa kodaba olumisiwe esimweni esixubile sezinto eziphilayo kanye ne-inorganic, futhi isisombululo sine-acidic noma singathathi hlangothi.
Ukulungiselela i-Flocculant
I-flocculant ingaba yisigaba esiqinile noma isigaba esiphezulu se-liquid. Uma le flocculant yengezwe ngokuqondile ekumisweni, ngenxa yokuminyana kwayo okuphezulu kanye nezinga eliphansi lokusabalalisa, i-flocculant ayikwazi ukuhlakazeka kahle ekumisweni, okuholela ekutheni ingxenye ye-flocculant ingakwazi ukudlala indima ye-flocculation, okuholela ekulahlekeni kwe-flocculant. . Ngakho-ke, i-mixer encibilikayo iyadingeka ukunyakazisa i-flocculant kanye nenani elifanele lamanzi ukuze kufinyelelwe ekugxiliseni okuthile, ngokuvamile kungabi ngaphezu kuka-4~5g/L, futhi ngezinye izikhathi ngaphansi kwaleli nani. Ngemuva kokuxubha ngokulinganayo, ingasetshenziswa. Isikhathi sokupheka cishe amahora angu-1-2.
Ngemuva kokuthi i-polymer flocculant isilungisiwe, isikhathi sayo sokuqinisekisa siyi-2 ~ 3d. Uma ikhambi liba mhlophe qhwa, kusho ukuthi isixazululo siwohlokile futhi siphelelwe yisikhathi, futhi kufanele simiswe ngokushesha.
Iqembu le-amide le-polyacrylamide elikhiqizwe yi-Yixing Cleanwater Chemicals Co., Ltd. lingaba ubudlelwano nezinto eziningi, i-adsorb futhi lenze amabhondi e-hydrogen. I-polyacrylamide enesisindo esilinganiselwe esiphezulu yakha amabhuloho phakathi kwama-ion adsorbed, ikhiqiza ama-flocs, futhi isheshisa ukuvela kwezinhlayiya, ngaleyo ndlela ifinyelele umgomo wokugcina wokuhlukaniswa koketshezi oluqinile. Kunezinhlobo ze-anionic, ze-cationic nezingezona i-ionic. Ngasikhathi sinye, amakhasimende angakwazi futhi ukwenza ngezifiso imikhiqizo yokucaciswa okuhlukile
Umusho wokuzihlangula: Sigcina isimo sengqondo sokungathathi hlangothi mayelana nemibono ekulesi sihloko. Le ndatshana ingeyereferensi kuphela, ukusetshenziswa kokuxhumana, hhayi okokuhweba, futhi i-copyright ingeyombhali wokuqala. Siyabonga ngokunaka kwakho nokusekelwa!
