activated carbon for Gas Purification and Environmental use
Mpweya wokhala ndi activated umagwiritsidwa ntchito mosiyanasiyana pamakina onse a gasi ndi mpweya wotulutsa mpweya. Monga chonyamulira sing'anga kwa wapadera impregnating wothandizira kapena chothandizira, adamulowetsa mpweya ndi zothandiza kuchira zosungunulira, mu kuyeretsedwa kwa ndondomeko mpweya, kuchotsa dioxins, heavy zitsulo, organic zosafunika. Nthawi zambiri amagwiritsidwa ntchito kuchotsa zowononga mu air conditioner ndi exhaust system. Itha kugwiritsidwanso ntchito kuchotsa zinthu zonunkhiza m'makitchini chakudya ndi zosefera mufiriji.
M'mafakitale amagetsi, zotenthetsera, ndi ng'anjo za simenti, mpweya woyatsidwa umachotsa mercury, dioxin, furan, ndi zowononga zina kuchokera ku mpweya wotulutsa mpweya kuti zikwaniritse malamulo a chilengedwe.
Zodziwika m'masefa am'mafakitale komanso okhalamo kuti achotse ma VOC, fungo, ndi mankhwala opangidwa ndi mpweya.
Mpweya wopangidwa ndi mpweya wopangidwa kuti uchotse zinthu zopanda organic monga zitsulo zolemera, ammonia kapena H.2S.
Ma Dioxins/Furans ndi gulu la zinthu zomwe zimapitilira komanso zapoizoni kwambiri, zomwe zimawonongeka pang'onopang'ono ndi kuyaka kosakhazikika, koma amapangidwanso panthawi yolekanitsa fumbi pa kutentha kopitilira 200 ° C.
Mercury ndi imodzi mwazinthu zomwe sizipezeka m'chilengedwe. Komabe, chifukwa cha kuthamanga kwake kwa nthunzi komanso kusungunuka mosavuta kuchokera kumagulu amankhwala, kuopsa kwa mpweya ku chilengedwe kulipo m'mafakitale ambiri. Chifukwa cha kawopsedwe kambiri ka mercury ndi mankhwala ake, kuyesetsa kulikonse kuyenera kuchitika kuti tipewe kutulutsa kotereku. Zomwe zimachokera ku mpweya wa mercury kupita kumlengalenga ndi njira zazitsulo ndi kupanga ndi kutaya zinthu zomwe zili ndi mercury. Mercury imatha kuchotsedwa pakuyenda kwa gasi pogwiritsa ntchito njira zosiyanasiyana zotsuka.
Ma parameter otsatirawa nthawi zambiri amagwiritsidwa ntchito kudziwa kuchuluka kwa kuipitsa:
- TOC (kusungunuka kaboni carbon)
- COD (chemical oxygen demand)
- AOX (absorbable organic halogens)
Kafukufuku akuyenera kuchitidwa kuti afufuze mtundu wa machitidwe a adsorption a zowononga potengera zomwe zili pamwambazi. Pambuyo pake, zomwe zapezedwa zimalola kutsimikiza kwamtundu woyenera wa carbon activated kuti athane ndi kuipitsa.
Kukhala ndi mulingo wotetezeka wa BOD m'madzi oyipa ndikofunikira pakutulutsa utsi wabwino. Ngati mlingo wa BOD uli wochuluka kwambiri, ndiye kuti madziwo akhoza kukhala pachiopsezo chowonjezereka, kusokoneza njira yochizira komanso kukhudza mapeto. COD ndi ntchito yomwe nthawi zambiri imagwiritsidwa ntchito pamafakitale; komabe, ma municipalities omwe amatsuka madzi otayira ndi mankhwala owononga mankhwala akhoza kuwagwiritsanso ntchito.
Ndife ogulitsa kwambiri ku China, pamtengo kapena zambiri zolandilidwa kulumikizana nafe pa:
