Ukuguquguquka kwekhabhoni ecushiwe akupheli, kunezinhlelo zokusebenza ezaziwayo ezingaphezu kwe-1,000 ezisetshenziswayo.Ukusuka ezimayini zegolide kuya ekuhlanzweni kwamanzi, ukukhiqizwa kwezinto zokudla nokunye, ikhabhoni ecushiwe ingenziwa ngendlela oyifisayo ukuhlangabezana nezidingo eziningi ezithize.
Amakhabhoni acushiwe enziwa ngezinto ezihlukene zomthombo we-carbonaceous - okuhlanganisa amagobolondo kakhukhunathi, i-peat, izinkuni eziqinile nezithambile, amalahle e-lignite nomgodi womnqumo ukubala nje ezimbalwa.Kodwa-ke, noma yiziphi izinto eziphilayo ezinokuqukethwe okuphezulu kwekhabhoni zingasetshenziswa ngempumelelo ukudala amakhabhoni acushiwe ngokuguqulwa komzimba nokubola okushisayo.
Ukusetshenziswa okuvame kakhulu kwekhabhoni ecushiwe emhlabeni wanamuhla kuzungeza ekuphathweni kwamanzi acutshungulwayo, amanzi angcolile ezimbonini nawezohwebo kanye nezinkinga zokunciphisa umoya/iphunga.Uma iguqulelwa kumakhabhoni acushiwe, izinto zomthombo we-carbonaceous zinamandla okuhlanza ngempumelelo nokususa ukungcola okuningi emanzini nasemifudlaneni yamanzi angcolile.
Iqhaza eliwujuqu lekhabhoni ecushiwe ekwelashweni kwamanzi (enye yamakhemikhali okuhlanza amanzi)
Amakhabhoni acushiwe anikeza enye yezindlela eziphumelela kakhulu zokususa ukungcola okubalulekile njenge-THM ne-DBP kanye nokukhipha izakhi eziphilayo nezibulala-magciwane ezisele emanzini.Lokhu akuthuthukisi kuphela ukunambitheka nokunciphisa izingozi zezempilo kodwa kuvikela amanye amayunithi okwelapha amanzi afana nolwelwesi lwe-osmosis oluhlehlayo kanye nama-ion exchange resins ekulimaleni okungaba khona ngenxa ye-oxidation noma ukungcola kwemvelo.
Ikhabhoni ecushiwe iyaqhubeka nokuba ngenye yezindlela zokuhlanza amanzi ezithandwa kakhulu kulo lonke elase-UK nase-Ireland ngenxa yezinhlelo zayo ezingavamile zokusebenza nemisebenzi.
Izinhlobo zamakhabhoni acushiwe
Ikhabhoni ecushiwe ivamise ukusetshenziselwa ukwelapha amanzi acutshungulwa ngezinqubo ezimbili ezihluke kakhulu – amakhabhoni ayimpuphu acushwe (PAC) namakhabhoni acushiwe ayimbudumbudu (GAC).Kodwa-ke, izindlela zomthamo kanye nezimo zokusebenzisa zalezi zinhlobo zamakhabhoni acushiwe ziyehluka kakhulu.Ukukhethwa kohlobo oluthile lwamakhabhoni acushiwe ukuze kuhlanzwe amanzi kuzoncika kuhlobo lohlelo oluthile, umphumela odingekayo kanye nanoma yimiphi imikhawulo yenqubo ekhona.
I-Powdered Activated Carbons isetshenziswa izitshalo zokuhlanza amanzi ukulawula ukunambitha kanye nephunga kanye nokuqinisekisa ukususwa kwamakhemikhali emvelo.Ama-PAC engezwa ekuqaleni kwenqubo yokwelapha ukuze kunikwe amandla inkathi yesikhathi sokuxhumana esisodwa ngaphambi kokuba amanye amakhemikhali okwelapha engezwe emfudlaneni wamanzi.
Akufanele zimbozwe nanoma yimaphi amanye amakhemikhali okuhlanza amanzi ngaphambi kokuba zivunyelwe ukuthintana nesikhathi esanele sokuthintana nomfudlana wamanzi (imvamisa ama-PAC azodinga okungenani imizuzu eyi-15 isikhathi esisodwa sokuthintana nomfudlana wamanzi).Okubaluleke kakhulu, i-PAC akufanele neze yengezwe kanyekanye ne-chlorine noma i-potassium permanganate njengoba lawo makhemikhali okuhlanza amanzi azomane akhangwe yimpushana yekhabhoni ecushiwe.
Imithamo edingekayo evamile ingaba noma yikuphi phakathi kuka-1 kuya ku-100 mg/L kuye ngohlobo nezinga lokungcola, kodwa imithamo engu-1 kuye ku-20 mg/L ijwayeleke kakhulu lapho kwelapha ukugeleza kwamanzi ngenjongo yokunambitha nokulawula iphunga.Kuzodingeka imithamo ephakeme lapho ama-PAC engezwa kamuva enqubweni yokwelapha, ukuze kuvunyelwe noma yikuphi ukukhangisa kwamanye amakhemikhali okwelapha angezwe ekuqaleni kwenqubo.Kamuva ama-PAC akhishwa emifudlaneni yamanzi ngenqubo yenhlabathi noma ngemibhede yokuhlunga.
I-Hebei medipharm co., Ltd ingabahlinzeki abahamba phambili be-carbon ecushiwe.we sinikeza uhla oluhluke kakhulu lwezimpushana zekhabhoni ezicushiwe kanye nama-granules ekhabhoni acushiwe emakethe.Uma udinga ulwazi olwengeziwe ngohlu lwethu lwamakhabhoni acushiwe noma unombuzo wethimba lethu lochwepheshe, sicela ukhululeke ukuxhumana.
