Nyob rau niaj hnub no cov khoom siv dej muaj txiaj ntsig ntau zuj zus, yuav ua li cas kom huv huv thiab nyab xeeb ntawm cov dej zoo tau dhau los ua qhov teeb meem tseem ceeb rau kev tiv thaiv ib puag ncig thiab kev noj qab haus huv rau pej xeem. Cov pa roj carbon activated rau kev kho dej, raws li cov khoom siv ua kom zoo thiab muaj txiaj ntsig adsorbent, tseem ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv kev ua dej huv vim nws lub cev thiab tshuaj lom neeg tshwj xeeb. Nws tsis yog tsuas yog "ntxuav" hauv kev kho dej siv thev naus laus zis, tab sis kuj yog ib qho tseem ceeb ntawm kev tiv thaiv kev nyab xeeb ntawm cov dej haus.
Lub ntsiab kom zoo dua ntawm cov pa roj carbon activated rau kev kho dej yog nyob rau hauv nws qhov loj tshwj xeeb thaj chaw thiab nplua nuj pore qauv. Qhov chaw saum npoo ntawm txhua gram ntawm cov pa roj carbon activated tuaj yeem sib npaug rau ntau qhov chaw ncaws pob, thiab qhov kev tsim kho microporous no ua rau nws muaj peev xwm adsorb organic pollutants, residual chlorine, ntxhiab tsw, thiab qee qhov hnyav hlau ions hauv dej. Nyob rau hauv cov txheej txheem kev kho dej siab tshaj plaws, cov pa roj carbon activated rau kev kho dej feem ntau yog siv rau hauv cov theem pom, tshem tawm cov kab mob tsis zoo uas nyuaj rau tshem tawm los ntawm cov txheej txheem ib txwm muaj, xws li tshuaj tua kab thiab tshuaj tua kab mob los ntawm - cov khoom, txhim kho qhov zoo ntawm effluent.
Tsis tas li ntawd, activated carbon rau kev kho dej kuj muaj tshuaj lom neeg ruaj khov thiab biocompatibility. Nws tsis tsim teeb meem los ntawm - cov khoom thaum lub sij hawm adsorption txheej txheem thiab tsis ua rau cov pa phem thib ob, uas yog raws li txoj kev loj hlob lub tswv yim ntawm kev kho dej ntsuab. Nyob rau tib lub sijhawm, cov pa oxygen- muaj cov pab pawg ua haujlwm nplua nuj nyob rau saum npoo ntawm cov pa roj carbon activated tuaj yeem ua rau cov tshuaj chlorine decomposition, tiv thaiv ion pauv resins lossis rov qab osmosis membranes hauv cov txheej txheem tom ntej, thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom siv. Tom qab ib lub sij hawm ntawm kev siv, saturated activated carbon tuaj yeem rov qab tau nws lub peev xwm adsorption los ntawm txoj kev xws li thermal regeneration, ua tiav cov peev txheej rov ua dua tshiab.
Nrog rau qhov nyuaj ntawm cov dej paug ntau zuj zus, cov pa roj carbon activated rau kev kho dej yog sib sib zog nqus nrog cov txheej txheem tshiab xws li biofilters thiab membrane technology, ua kom muaj kev sib xyaw ua ke ntawm "activated carbon +" txhawm rau txhim kho kev ua kom huv. Nyob rau hauv lub neej yav tom ntej, los ntawm kev hloov kho cov khoom siv thiab cov txheej txheem optimization, activated carbon rau kev kho dej yuav ua rau pom muaj peev xwm ntau dua los daws cov teeb meem tshwm sim thiab ua tiav kev ua haujlwm ntse.
Cov pa roj carbon activated yog siv rau kev kho dej kom huv huv txhua qhov dej nrog lub zog ntawm cov thev naus laus zis, ntsiag to sau ib tshooj ntsuab ntawm kev sib haum xeeb ntawm tib neeg thiab xwm.
