Cov pa roj carbon activated, raws li cov khoom muaj peev xwm adsorption siab, plays lub luag haujlwm tseem ceeb hauv kev lag luam khoom noj. Nws daim ntawv thov suav nrog ntau yam piv txwv li raw khoom purification, kev tsim khoom, thiab kev kho dej khib nyiab. Los ntawm cov nyhuv ntawm lub cev adsorption thiab tshuaj adsorption, nws ua tiav ntau lub hom phiaj nrog rau kev tshem tawm impurity, kev txhim kho kom zoo, thiab lwm yam.Cov hauv qab no yuav muab cov lus piav qhia ntxaws txog kev siv cov pa roj carbon activated hauv kev lag luam khoom noj.
Thaum lub sijhawm ua ntej -kev kho mob ntawm cov khoom siv raw khoom, lub luag haujlwm tseem ceeb ntawm cov pa roj carbon activated yog tshem tawm cov xim, tsw, thiab lwm yam los ntawm cov khoom siv raw. Xws li, nyob rau hauv kev lag luam qab zib, cov kua qab zib crude tau los ntawm cov suab thaj los yog qab zib beet pressing muaj impurities xws li melanoidins thiab caramel pigments. Cov txheej txheem nag lossis daus yog qhov nyuaj rau tshem tawm cov impurities tag nrho, thaum lub tshuab ua kom cov pa roj carbon monoxide, nrog nws cov qauv tsim microporous, tuaj yeem nqus tau cov xim macromolecular thaum khaws cov qab zib thiab cov khoom noj muaj txiaj ntsig ntawm cov suab thaj, ua kom tiav cov qab zib dawb mus txog lub crystal- qauv ntshiab. Ib yam li ntawd, hauv kev ua cov kua txiv hmab txiv ntoo, cov kua roj carbon activated tuaj yeem xaiv adsorb phenolic oxidation cov khoom thiab iab saj Cheebtsam hauv cov kua txiv hmab txiv ntoo, txhim kho qhov pom tseeb thiab txhim kho qhov saj, tshwj xeeb tshaj yog nyob rau hauv kev lag luam ntawm cov kua txiv hmab txiv ntoo thiab kua txiv hmab txiv ntoo, qhov twg activated carbon hmoov kho tau dhau los ua cov txheej txheem txheem.
Kev ua kom huv huv hauv cov txheej txheem tsim khoom yog lwm qhov tseem ceeb ntawm kev siv cov pa roj carbon activated. Hauv kev ua kom zoo ntawm cov roj siv tau, cov pa phem xws li cov roj ntsha dawb, phospholipids, cov hlau hnyav, thiab lwm yam hauv cov roj ntsha tuaj yeem cuam tshuam rau kev ruaj ntseg thiab kev nyab xeeb ntawm cov roj. Los ntawm kev ntxiv cov zaub mov- qib hmoov activated carbon thiab siv nws qhov chaw nplua nuj ua haujlwm pab pawg los tsim hydrogen bonds lossis electrostatic attractions nrog cov pa phem, tus nqi peroxide thiab cov ntsiab lus hlau hnyav hauv cov roj ua kom zoo tuaj yeem txo qis, ua kom cov roj refined ua tau raws li cov qauv kev nyab xeeb hauv teb chaws. Hauv kev lag luam khoom noj fermentation, xws li hauv kev tsim cov monosodium glutamate thiab citric acid, activated carbon hmoov feem ntau yog siv los tshem tawm cov kab mob fungal, protein colloids, thiab metabolic los ntawm - cov khoom los ntawm cov kua fermentation, txhim kho cov khoom purity. Piv txwv li, nyob rau hauv zus tau tej cov monosodium glutamate, los ntawm activated carbon hmoov desaturation, lub whiteness ntawm glutamic acid sodium crystals yuav nce mus txog 95%.
Kev kho cov khoom noj khoom haus cov dej khib nyiab yog qhov ua kom pom tseeb ntawm kev tiv thaiv ib puag ncig tus nqi ntawm cov pa roj carbon activated. Cov dej khib nyiab uas tsim thaum lub sij hawm ua zaub mov muaj cov ntsiab lus ntawm cov organic teeb meem, roj, thiab xim, thiab tso tawm ncaj qha yuav ua rau dej lub cev eutrophication. Siv cov thee-raws kem- zoo li cov pa roj carbon monoxide ua cov khoom siv rau cov lim dej lom neeg, tsis yog nws tuaj yeem tshem COD thiab BOD los ntawm cov dej khib nyiab los ntawm lub cev adsorption, tab sis nws cov qauv ntxeem tau kuj tuaj yeem muab cov substrate rau cov kab mob, ua rau "adsorption- biodegradation" synergy, nce 30% kev kho dej pov tseg {8% Piv txwv li, tom qab lub tuam txhab npias dej khib nyiab raug kho los ntawm cov txheej txheem ua kom cov pa roj carbon-biological ua ke, COD tshem tawm tus nqi tuaj yeem ncav cuag ntau dua 90%, thiab cov dej ntws rov qab tuaj yeem rov qab siv dua rau kev cog qoob loo lossis khoom siv tu, ua tiav cov peev txheej dej rov qab.
Tsis tas li ntawd, cov pa roj carbon activated tseem ua lub luag haujlwm zais hauv kev lees paub kev nyab xeeb ntawm cov khoom noj khoom haus. Cov kuab tshuaj nyob hauv cov yeeb yaj kiab yas siv rau ntim khoom noj thiab cov tshuaj tsis haum cov organic hauv cov ntawv luam tawm tuaj yeem txav mus los thiab paug cov zaub mov. Los ntawm kev ntxiv cov activated carbon hmoov masterbatch thaum lub sij hawm tsim cov yeeb yaj kiab, cov khoom tsis zoo no tuaj yeem adsorbed thiab solidified, txo qhov kev pheej hmoo ntawm kev tsiv teb tsaws thiab ua kom muaj kev nyab xeeb ntawm cov khoom ntim khoom noj.
Los ntawm kev sib sib zog nqus purification ntawm ntuj raw cov ntaub ntawv mus rau qhov zoo optimization ntawm cov khoom kawg, los ntawm kev ua raws li cov khoom pov tseg pov tseg mus rau kev ruaj ntseg ntawm cov ntaub ntawv ntim, activated carbon, nrog rau nws npaum, ib puag ncig tus phooj ywg, thiab tsawg - tus nqi zoo, dhau los ua cov khoom tseem ceeb rau kev loj hlob ntawm kev lag luam khoom noj. Raws li cov qauv kev nyab xeeb kev lag luam khoom noj txuas ntxiv txhim kho, kev tshawb fawb thiab kev siv cov hloov kho cov pa roj carbon monoxide yuav nthuav dav nws lub peev xwm hauv kev ua haujlwm huv thiab muab kev txhawb nqa rau kev hloov kho ntsuab ntawm kev lag luam zaub mov.
