Kodi mukudziwa chiyani pa activated carbon?

Kodi activated carbon imatanthauza chiyani?

Activated carbon ndi zinthu zachilengedwe zosinthidwa zomwe zimakhala ndi mpweya wambiri.Mwachitsanzo, malasha, nkhuni kapena kokonati ndi zipangizo zabwino za izi.Zotsatira zake zimakhala ndi porosity yayikulu ndipo zimatha kutsitsa mamolekyu a zoipitsa ndikuzigwira, motero amayeretsa mpweya, mpweya ndi zakumwa.

Ndi mitundu yanji yomwe carbon activated ingapatsidwe?

Mpweya wopangidwa ndi activated ukhoza kupangidwa mwamalonda mu mitundu ya granular, pelletized ndi ufa.Kukula kosiyanasiyana kumatanthauzidwa pazantchito zosiyanasiyana.Mwachitsanzo, pochiza mpweya kapena gasi, lamulo loletsa kuyenda ndi lochokera kunja, motero tinthu tambirimbiri timagwiritsidwa ntchito kuti tichepetse kuthamanga.Mu mankhwala amadzimadzi, pomwe njira yochotserayo imachedwa pang'onopang'ono, ndiye kuti tinthu tating'onoting'ono tating'onoting'ono timagwiritsidwa ntchito kukonza mlingo, kapena kinetics, njira yoyeretsera.

Kodi activated carbon imagwira ntchito bwanji?

Carbon activated imagwira ntchito ndi njira ya adsorption.Ichi ndi chokopa cha molekyulu kumtunda waukulu wamkati wa kaboni ndi mphamvu zofooka, zomwe zimadziwika kuti London forces.Molekyuyi imagwiridwa ndipo silingachotsedwe, pokhapokha ngati zinthu zikusintha, mwachitsanzo kutentha kapena kupanikizika.Izi zitha kukhala zothandiza chifukwa mpweya woyaka ungagwiritsidwe ntchito kuyika zinthu pamwamba pake zomwe pambuyo pake zimatha kuvula ndikubwezeretsanso.Kugwiritsa ntchito activated carbon pobwezeretsa golide ndi chitsanzo chimodzi cha izi.

Nthawi zina, carbon activated ndi mankhwala mankhwala kuchotsa zoipitsa ndipo pamenepa zotsatira anachita pawiri zambiri anachira.

Mpweya wa carbon activated nawonso sukhala wokwanira, ndipo njira zosiyanasiyana zothandizira zingatheke pogwiritsa ntchito ndikugwiritsa ntchito mwayi wotalikirapo wamkati womwe ulipo.

Kodi carbon activated pa mapulogalamu ndi chiyani?

Ma Carbon Ogwiritsidwa Ntchito ali ndi ntchito zambiri zosiyanasiyana kuyambira kusefera mpaka kuyeretsedwa ndi kupitilira apo.

M'zaka zaposachedwa, kuchulukira komanso kuchuluka kwa zovuta za kukoma ndi fungo lamadzi akumwa zakula padziko lonse lapansi.Kupitilira vuto la kukongola kwa ogula, izi zimabweretsanso kusatsimikizika pazabwino ndi chitetezo cha madzi.Zosakaniza zomwe zimayambitsa zovuta za kukoma ndi fungo zimatha kukhala ndi anthropogenic (zotulutsa m'mafakitale kapena zamatawuni) kapena chiyambi chachilengedwe.Pamapeto pake, amapangidwa ndi tizilombo tosaoneka ndi maso monga cyanobacteria.

Mitundu iwiri yodziwika bwino ndi geosmin ndi 2-methylisoborneol (MIB).Geosmin, yomwe imakhala ndi fungo la nthaka, nthawi zambiri imapangidwa ndi planktonic cyanobacteria (yoyimitsidwa m'madzi).MIB, yomwe imakhala ndi fungo lonunkhira, imapangidwa nthawi zambiri mu biofilm yomwe ikukula pamiyala, zomera zam'madzi ndi dothi.Mankhwalawa amazindikiridwa ndi maselo amunthu omwe amanunkhiza m'malo otsika kwambiri, ngakhale m'magulu angapo pa thililiyoni (ppt, kapena ng/l).

Njira zochiritsira zamadzi nthawi zambiri sizingachotse MIB ndi geosmin kuti zitsike pang'onopang'ono momwe amakondera komanso amanunkhiza, zomwe zimapangitsa kugwiritsa ntchito kaboni woyamwa pakugwiritsa ntchito.Njira yodziwika bwino yogwirira ntchito ndi ya ufa wothira mpweya (PAC), womwe umalowetsedwa mumtsinje wamadzi pakanthawi kochepa kuti athetse vuto la kukoma ndi fungo.
