Ikhabhoni ecushiwe isetshenziswa kakhulu empilweni yethu, futhi umthamo wayo omuhle we-adsorption uthandwa kakhulu.Isihlungi sekhabhoni esicushiwe siyidivayisi yokuhlunga yomzimba wethangi.Ingaphandle ngokuvamile yenziwe nge-glass fiber reinforced plastic, kanti ingaphakathi ligcwele ikhabhoni ecushiwe, engahluza ama-microorganisms namanye ama-ion ensimbi esindayo emanzini, futhi inganciphisa umbala wamanzi.Ngakho-ke lesi sihlungi sekhabhoni esicushiwe sisebenza kanjani?
Umgomo wokukhangiswa kwekhabhoni ecushiwe uwukwenza ungqimba lokugxiliswa kwendawo okulinganiselwe phezu kwezinhlayiya zayo.Usayizi wezinhlayiya zekhabhoni ecushiwe nawo unomphumela kumthamo we-adsorption.Ngokuvamile, ezincane izinhlayiya zekhabhoni ezicushiwe, indawo yokuhlunga inkulu.Ngakho-ke, ikhabhoni ecushiwe eyimpuphu inendawo enkulu kunazo zonke kanye nomphumela omuhle kakhulu we-adsorption, kodwa ikhabhoni ecushiwe eyimpuphu igeleza kalula ethangini lamanzi, okunzima ukuyilawula futhi ayivamisile ukusetshenziswa.I-Granular activated carbon akulula ukugeleza ngenxa yokwakheka kwezinhlayiya, futhi ukungcola okufana ne-organic matter emanzini akulula ukukuvimba kungqimba lwesihlungi se-carbon esicushiwe.Inamandla okukhangisa futhi kulula ukuyiphatha nokuyishintsha.
Umthamo we-adsorption wekhabhoni ecushiwe ulingana nesikhathi sokuthintana namanzi.Uma isikhathi sokuxhumana siba side, iba ngcono ikhwalithi yamanzi ahlungiwe.Qaphela: Amanzi ahlungiwe kufanele aphume kancane kungqimba lokuhlunga.Ikhabhoni entsha ecushiwe kufanele igezwe ihlanzeke ngaphambi kokusetshenziswa kokuqala, ngaphandle kwalokho kuzoba namanzi amnyama aphumayo.Ngaphambi kokuba ikhabhoni ecushiwe ilayishwe esisefweni, isipontshi esinogqinsi luka-2 kuya ku-3 cm kufanele sengezwe phansi nangaphezulu ukuvimbela ukungena kwezinhlayiya ezinkulu zokungcola okufana ne-algae.Ngemuva kokuthi ikhabhoni ecushiwe isetshenziswe izinyanga ezi-2 kuya kwezi-3, uma umphumela wokuhlunga wehla, kufanele ushintshwe.Ikhabhoni entsha ecushiwe, ungqimba lwesipontshi kufanele futhi lushintshwe njalo.
Into yokuhlunga kusikhangisi esicushiwe sesihlungi sekhabhoni ingagcwaliswa ngesihlabathi sequartz esinobude obungamamitha angu-0.15~0.4 ngaphansi.Njengesendlalelo sokusekela, izinhlayiya zesihlabathi se-quartz zingaba ngu-20-40 mm, futhi isihlabathi se-quartz singagcwaliswa nge-carbon activated granular yamamitha angu-1.0-1.5.njengesendlalelo sokuhlunga.Ubukhulu bokugcwalisa ngokuvamile buyi-1000-2000mm.
Ngaphambi kokuthi kushajwe isihlungi sekhabhoni esicushiwe, isihlungi se-quartz esingaphansi kufanele sihlolwe ukuqina kwesixazululo.Ngemva kokucwiliswa emanzini amahora angu-24, lezi zidingo ezilandelayo ziyahlangatshezwa: ukwanda kwakho konke okuqinile akudluli ku-20mg/L.Ukwanda kokusetshenziswa komoyampilo akufanele kudlule i-10 mg/L.Ngemuva kokucwiliswa ku-alkaline medium, ukwanda kwe-silica akudluli ku-10mg/L.
Isihlabathi sequartz sesihlungi sekhabhoni esicushiwe kufanele sihlanzwe ngokucophelela ngemuva kokugezelwa emishinini.Ukugeleza kwamanzi kufanele kugezwe kusuka phezulu kuya phansi, futhi amanzi angcolile kufanele akhishwe kusukela phansi kuze kube yilapho kucaciswa ukungcola.Ngemuva kwalokho, into eyisihlungi se-granular ecushiwe kufanele ilayishwe, bese ihlanzwa.Ukugeleza kwamanzi kusuka phansi kuya phansi.Hlanza phezulu, amanzi angcolile aphuma phezulu.
Umsebenzi wesihlungi se-carbon esicushiwe ngokuyinhloko ukususa izinto eziphilayo ze-macromolecular, i-iron oxide ne-chlorine esele.Lokhu kungenxa yokuthi izinto eziphilayo, i-chlorine eyinsalela kanye ne-iron oxides kungaba ubuthi kalula ku-resin exchange ion, kuyilapho insalela ye-chlorine kanye ne-cationic surfactants ngeke nje yenze ubuthi ku-resin, kodwa futhi kulimaze ukwakheka kolwelwesi futhi yenze i-reverse osmosis membrane ingasebenzi.
Izihlungi ze-carbon activated zisetshenziswa kakhulu embonini.Abakwazi nje ukuthuthukisa ikhwalithi yamanzi okulahlwayo kuphela, kodwa futhi bavimbele ukungcoliswa, ikakhulukazi ukungcoliswa kobuthi be-oksijeni okuyinsalela yamahhala ye-back-stage osmosis membrane kanye ne-ion exchange resin.Isihlungi se-carbon esicushiwe asigcini nje ngokusebenza kahle okuphezulu, kodwa futhi sinezindleko eziphansi zokusebenza, ikhwalithi enhle yokugeleza kwamanzi kanye nomphumela omuhle wokuhlunga.
Uma uyidinga, mane uchofoze inkinobho engezansi.
