Ukuguquguquka kwe-activated carbon akupheli, kunezinhlelo zokusebenza ezingaphezu kwe-1,000 ezaziwayo ezisetshenziswayo. Kusukela ekuvubukuleni igolide kuya ekuhlanzweni kwamanzi, ukukhiqizwa kwezinto zokudla nokuningi, i-activated carbon ingenziwa ngokwezifiso ukuze ihlangabezane nezidingo eziningi ezithile.
Amakhabhoni asebenzayo enziwa ngezinto ezahlukahlukene zomthombo wekhabhoni - kufaka phakathi amagobolondo kakhukhunathi, i-peat, ukhuni oluqinile noluthambile, amalahle e-lignite kanye nomgodi womnqumo ukubala ezimbalwa nje. Kodwa-ke, noma yiziphi izinto eziphilayo ezinokuqukethwe okuphezulu kwekhabhoni zingasetshenziswa ngempumelelo ukudala amakhabhoni asebenzayo ngokuguqulwa ngokomzimba kanye nokubola kokushisa.
Ukusetshenziswa okuvame kakhulu kwe-activated carbon ezweni lanamuhla kugxile ekwelapheni amanzi angcolile ezinqubo, amanzi angcolile asezimbonini nawezentengiselwano kanye nezinkinga zokunciphisa umoya/iphunga. Uma kuguqulwa kube ama-activated carbon, izinto zomthombo we-carbonaceous zinekhono lokuhlanza nokususa ngempumelelo uhla olubanzi lwezinto ezingcolisayo emanzini nasemifudlaneni yamanzi angcolile.
Indima ebalulekile yekhabhoni esebenzayo ekuphathweni kwamanzi (enye yamakhemikhali okwelashwa kwamanzi)
Amakhabhoni asebenzayo anikeza enye yezindlela eziphumelela kakhulu zokususa ukungcola okubalulekile njenge-THM ne-DBP kanye nokususa izinto eziphilayo kanye nezibulala-magciwane ezisele emanzini. Lokhu akugcini nje ngokuthuthukisa ukunambitheka futhi kunciphisa izingozi zempilo kodwa kuvikela nezinye izikhungo zokwelashwa kwamanzi njenge-reverse osmosis membranes kanye nama-ion exchange resins ekulimaleni okungenzeka ngenxa ye-oxidation noma i-organic fouling.
I-activated carbon isaqhubeka nokuba enye yezindlela zokwelapha amanzi ezithandwa kakhulu kulo lonke elase-UK nase-Ireland ngenxa yezinhlelo zayo zokusebenza nemisebenzi ehlukahlukene.
Izinhlobo zama-carbon asebenzayo
I-activated carbon ivame ukusetshenziswa ukwelapha amanzi enqubo ngezinqubo ezimbili ezihlukene kakhulu - ama-activated carbons ayimpuphu (PAC) nama-granular activated carbons (GAC). Kodwa-ke, izindlela zomthamo kanye namacala okusetshenziswa kwalezi zinhlobo zama-activated carbons ziyahlukahluka kakhulu. Ukukhethwa kohlobo oluthile lwama-activated carbons okwelashwa kwamanzi kuzoncika ohlotsheni lokusetshenziswa okuthile, umphumela odingekayo kanye nanoma yimiphi imikhawulo yenqubo ekhona.
Ama-carbon asebenzayo aphuzwayo asetshenziswa izitshalo zokwelapha amanzi ukulawula ukunambitheka nephunga nokuqinisekisa ukususwa kwamakhemikhali e-organic. Ama-PAC ayengezwa ekuqaleni kwenqubo yokwelapha ukuze kuvunyelwe isikhathi sokuxhumana sodwa ngaphambi kokuba amanye amakhemikhali okwelapha engezwe emseleni wamanzi.
Akufanele zimbozwe ngamanye amakhemikhali okwelapha amanzi ngaphambi kokuba zinikezwe isikhathi esanele sokuxhumana nomfula wamanzi (ngokuvamile ama-PAC azodinga okungenani imizuzu eyi-15 yokuxhumana kuphela nomfula wamanzi). Okubaluleke kakhulu, ama-PAC akufanele neze afakwe kanyekanye ne-chlorine noma i-potassium permanganate njengoba lawo makhemikhali okwelapha amanzi azomane amuncwe yimpuphu yekhabhoni esebenzayo.
Imithamo ejwayelekile edingekayo ingaba phakathi kuka-1 kuya ku-100 mg/L kuye ngohlobo kanye nezinga lokungcola, kodwa imithamo engu-1 kuya ku-20 mg/L ivame kakhulu lapho kuphathwa khona imifudlana yamanzi ngenhloso yokulawula ukunambitheka nephunga. Imithamo ephezulu izodingeka lapho ama-PAC engezwa kamuva enkambisweni yokwelapha, ukuvumela noma yikuphi ukumuncwa kwamanye amakhemikhali okwelapha afakwe ekuqaleni kwenqubo. Ama-PAC kamuva asuswa emifudlaneni yamanzi ngenqubo yokuthuthwa noma ngemibhede yokuhlunga.
I-Hebei medipharm co.,Ltd ingabahlinzeki abahamba phambili be-activated carbon. Sinikeza uhla oluhlukahlukene kakhulu lwe-activated carbon powders kanye ne-activated carbon granules emakethe. Uma udinga ulwazi olwengeziwe mayelana nohla lwethu lwe-activated carbons noma unemibuzo eqenjini lethu lochwepheshe, sicela ukhululeke ukuxhumana nathi.
