Kunezinhlobo eziningi ze-flocculants, ezingahlukaniswa ngezigaba ezimbili, enye i-flocculants ezingaphili kanti enye i-flocculants ephilayo.
(1) Izinto zokufaka ezingaphili: okuhlanganisa izinhlobo ezimbili zosawoti wensimbi, usawoti wensimbi nosawoti we-aluminium, kanye nezinto zokufaka ezingaphili ze-polymer ezifanai-polyaluminum chlorideEzivame ukusetshenziswa yilezi: i-ferric chloride, i-ferrous sulfate, i-ferric sulfate, i-aluminium sulfate (alum), i-basic aluminium chloride, njll.
(2) Ama-flocculant e-organic: ikakhulukazi izinto ze-polymer ezifana ne-polyacrylamide. Ngenxa yokuthi ama-flocculant e-polymer anezinzuzo ezilandelayo: umthamo omncane, izinga lokushelela okusheshayo, amandla aphezulu e-floc, kanye nekhono lokukhulisa isivinini sokuhlunga, umphumela wawo we-flocculation mkhulu ngokuphindwe kaningana kuya kaningi kunowe-flocculant yendabuko engaphili, ngakho-ke okwamanje isetshenziswa kabanzi kumaphrojekthi okwelapha amanzi.

I-flocculant ye-polymer--polyacrylamide
Izinto eziyinhloko zokusetshenziswai-polyacrylamide (i-PAM ngamafuphi)iyi-acrylonitrile. Ixutshwa namanzi ngesilinganiso esithile futhi itholakala ngokuswakama, ukuhlanzwa, ukwenziwa i-polymerization, ukomiswa nezinye izinqubo.
Iziphetho ezilandelayo zingatholakala ekuhlolweni kwangaphambilini:
(1) I-Anionic PAM ifaneleka ezintweni ezilengayo ezingaphili ezinokugxila okuphezulu kanye nokushaja okuhle, kanye nezinhlayiya ezilengayo eziqinile (0.01~1mm), kanye nenani le-pH elingathathi hlangothi noma le-alkaline.
(2) I-Cationic PAM ifaneleka ezintweni ezilengayo ezineshaja engemihle futhi eziqukethe izinto eziphilayo.
(3) I-Nonionic PAM ifanelekela ukuhlukaniswa kwezinto ezilengayo esimweni esixubile sezinto eziphilayo nezingaphili, futhi ikhambi line-acid noma alithathi hlangothi
Ukulungiswa kwe-Flocculant
I-flocculant ingaba isigaba esiqinile noma isigaba soketshezi olunezinga eliphezulu. Uma le flocculant ingezwa ngqo ku-suspension, 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 ekuchithekeni kwe-flocculant. Ngakho-ke, kudingeka umxube wokuncibilikisa ukuze uvuse i-flocculant kanye nenani elifanele lamanzi ukuze kufinyelelwe ukuminyana okuthile, ngokuvamile kungabi ngaphezu kuka-4~5g/L, futhi ngezinye izikhathi ngaphansi kwaleli nani. Ngemva kokuxuba ngokulinganayo, ingasetshenziswa. Isikhathi sokuxuba cishe singamahora angu-1~2.
Ngemva kokuba i-polymer flocculant isilungisiwe, isikhathi sayo sokusebenza siyizinsuku ezingu-2 ~ 3. Uma ikhambi liba mhlophe njengobisi, kusho ukuthi ikhambi seliwohlokile futhi seliphelelwe yisikhathi, futhi kufanele limiswe ngokushesha.
Iqembu le-amide le-polyacrylamide elikhiqizwa yi-Yixing Cleanwater Chemicals Co., Ltd. lingaba nobudlelwano nezinto eziningi, limunce futhi lakhe izibopho ze-hydrogen. I-polyacrylamide enesisindo sama-molecule esiphezulu yakha amabhuloho phakathi kwama-ion amoshiwe, ikhiqize ama-floc, futhi isheshise ukuthuthwa kwezinhlayiya, ngaleyo ndlela ifeze umgomo wokugcina wokuhlukaniswa koketshezi oluqinile. Kunezinhlobo ze-anionic, i-cationic kanye ne-non-ionic. Ngesikhathi esifanayo, amakhasimende angenza ngezifiso imikhiqizo yemininingwane ehlukene.
Isixwayiso: Sigcina isimo sengqondo sokungathathi hlangothi ngemibono ekulesi sihloko. Lesi sihloko singesokubhekisela kuphela, ukusetshenziswa kokuxhumana, hhayi ukusetshenziswa kwezentengiselwano, futhi ilungelo lokushicilela lingelombhali wokuqala. Siyabonga ngokunaka kwakho nokusekela kwakho!
