Chii chinorehwa ne activated carbon?
Activated kabhoni chinhu chakagadzirwa chakasikwa icho chakakwira mune kabhoni yemukati.Semuenzaniso, marasha, huni kana kokonati yakakwana mbishi zvinhu zveizvi.Chigadzirwa chinoguma chine porosity yakakura uye chinogona kushambadza mamorekuru ezvinosvibisa uye kuvateya, nekudaro kuchenesa mweya, magasi uye zvinwiwa.
Ndeapi mafomu anogona kupihwa activated carbon?
Activated kabhoni inogona kugadzirwa mukutengesa mune granular, pelletized uye hupfu mafomu.Kukura kwakasiyana kunotsanangurwa kune akasiyana maapplication.Semuyenzaniso, mukurapwa kwemhepo kana gasi, chirambidzo chekuyerera ndechekunze, uye saka zvimedu zvakakasharara zvinoshandiswa kudzikisa kurasikirwa kwekumanikidza.Mukurapa kwemvura, uko nzira yekubvisa inononoka, ipapo zvimedu zvakapfava zvinoshandiswa kuvandudza mwero, kana kinetics, yekuchenesa maitiro.
Ko activated carbon inoshanda sei?
Activated kabhoni inoshanda nekuita adsorption.Uku kukwezva kwemorekuru kune yakakura kabhoni mukati mepasi nemasimba asina simba, anozivikanwa seLondon forces.Iyo molecule inobatwa panzvimbo uye haigone kubviswa, kunze kwekunge mamiriro ekuita achinja, semuenzaniso kupisa kana kumanikidza.Izvi zvinogona kubatsira sezvo kabhoni yakabatidzwa inogona kushandiswa kutarisisa zvinhu pamusoro payo izvo zvinogona kuzokururwa uye kudzoreredzwa.Iko kushandiswa kweiyo activated kabhoni yekudzoreredza goridhe muenzaniso mumwe wakajairika weizvi.
Mune zvimwe zviitiko, iyo activated kabhoni inobatwa nekemikari kubvisa zvinosvibisa uye mune iyi kesi inokonzeresa inobatwa komputa kazhinji haiwanikwe.
Activated carbon surface hainawo inert zvachose, uye akasiyana-siyana ekugadzirisa maitiro anogona kuwanikwa uchishandisa uye kutora mukana weiyo yakawedzerwa yemukati nzvimbo inowanikwa.
Chii chinonzi activated carbon pane maapplication?
Activated Carbons ane akawanda akasiyana mashandisiro kubva kusefa kusvika kunatswa nekupfuura.
Mumakore achangopfuura, kusimba uye kuwanda kwekuravira uye kunhuwa matambudziko mumvura yekunwa kwakawedzera pasi rose.Kupfuura dambudziko rekunaka kune mutengi, izvi zvakare zvinogara zvichigadzira kusava nechokwadi nezvemhando uye kuchengetedzeka kwemvura.Mishonga inokonzeresa kuravira uye kunhuwa matambudziko anogona kuve neanthropogenic (kuburitswa kwemaindasitiri kana kwemanisipala) kana kwakabva biological.Muchiitiko chekupedzisira, ivo vanobudiswa ne microscopic zvipenyu zvakadai se cyanobacteria.
Iwo maviri akajairika makomisheni geosmin uye 2-methylisoborneol (MIB).Geosmin, ine kunhuhwirira kwevhu, inowanzobudiswa ne planktonic cyanobacteria (yakamiswa mumvura).MIB, ine kunhuhwirira kwakashata, inowanzogadzirwa mubiofilm inokura pamatombo, zvidyarwa zvemumvura uye sediment.Mishonga iyi inowonekwa nemasero anonhuwa emunhu pazvishoma zvakaderera, kunyangwe muchikamu chezvikamu zvishoma patiririyoni (ppt, kana ng/l).
Nzira dzakajairwa dzekurapa mvura kazhinji hadzigone kubvisa MIB uye geosmin kusvika pazasi kuravira kwavo uye kunhuwa zvikumbaridzo, izvo zvinotungamira mukushandiswa kweiyo activated kabhoni yechishandiso ichi.Nzira yakajairwa yebasa ndeye powdered activated kabhoni (PAC), iyo inoiswa mumvura murukova pane mwaka kudzora kuravira & kunhuwa nyaya.
