Ua ntej, kev nkag siab ntawm activated carbon
Raws li cov khoom siv niaj hnub thiab niaj hnub tsim, cov pa roj carbon activated yog tsim los ntawm cov ntsiab lus carbon. Vim lub pores sab hauv ntawm cov pa roj carbon activated thiab thaj chaw loj, yog li nws lub peev xwm adsorption kuj muaj zog.
Cov pa roj carbon activated tuaj yeem siv lub peev xwm adsorption kom tshem tawm cov teeb meem hauv dej, qhov tseem ceeb tshaj, cov pa roj carbon activated tuaj yeem txo qhov kev puas tsuaj rau cov dej tsis zoo, piv nrog rau lwm txoj hauv kev kho dej, activated carbon muaj cov yam ntxwv ntawm lub sijhawm ntev, qis. tus nqi, txawm tias nyob rau hauv cov txheej txheem ntawm kev kho dej yuav tsis tsim kev puas tsuaj rau tib neeg cov tshuaj noj qab haus huv.
Yog li ntawd, cov pa roj carbon activated tau dav lees paub los ntawm tib neeg, thiab siv dav hauv kev kho dej. Nyob rau tib lub sijhawm, vim muaj cov txheej txheem tsim khoom sib txawv, cov duab zoo nkauj thiab cov khoom siv raw, cov pa roj carbon activated tuaj yeem muab faib ua ntau hom.
Raws li cov txheej txheem tsim khoom, nws tuaj yeem muab faib ua lub cev ua kom cov pa roj carbon monoxide, tshuaj activated carbon, thiab lwm yam. Raws li qhov pom ntawm cov duab, tuaj yeem muab faib ua granular activated carbon, hmoov activated carbon, honeycomb activated carbon, activated carbon fiber. daim pam, activated carbon daim ntaub, activated carbon phaj thiab activated carbon fiber; Raws li lub hauv paus ntawm cov khoom siv raw, nws tuaj yeem faib ua ntxhib ntxhib rau hauv cov khoom siv ntxhia raw cov ntaub ntawv qhib tau carbon, ntoo qhib cov pa roj carbon monoxide thiab activated carbon ua los ntawm lwm cov ntaub ntawv raw, thiab lwm yam.
Feem ntau hais lus, hmoov activated carbon lossis granular activated carbon yog ntau dua hauv kev tsim khoom. Powdered activated carbon muaj qhov zoo ntawm qhov muaj peev xwm adsorption muaj zog thiab cov txheej txheem tsim khoom yooj yim, tab sis qhov tsis zoo yog qhov rov ua dua tus nqi qis, tsis tuaj yeem rov qab siv dua. Qhov zoo ntawm granular activated carbon yog kev tswj xyuas kev ua haujlwm, tuaj yeem rov qab siv dua tom qab tsim dua tshiab, tab sis qhov tsis zoo yog tus nqi siab dua. Nws tuaj yeem pom tias tsuas yog los ntawm kev nkag siab tag nrho cov pa roj carbon monoxide nws tuaj yeem siv tau zoo dua hauv kev kho dej.
Thib ob, lub luag haujlwm ntawm cov pa roj carbon activated hauv kev kho dej
Niaj hnub no, kev tsim khoom lag luam tau ua rau muaj kuab paug rau cov dej. Yuav kom daws tau qhov teeb meem ntawm dej paug, nws yog ib qho tsim nyog yuav tsum tau decontaminate cov dej los ntawm ntau yam txheej txheem. Cov pa roj carbon activated yog ntau yam sib txawv ntawm cov pa roj carbon adsorption muaj peev xwm thiab cov tshuaj adsorption sib txawv ntau dua. Txij li thaum xyoo 1990 los txog rau tam sim no, cov pa roj carbon activated tau siv los ua kom huv dej feem ntau txhawm rau tshem tawm cov trihalomethanes thiab cov pa phem me me. Vim tias trihalomethanes ntau dhau tuaj yeem ua rau tib neeg lub hlwb hloov pauv thiab ua rau mob qog noj ntshav, trihalomethanes yuav tsum raug tshem tawm thaum haus dej huv.
Feem ntau, cov dej lim dej siv cov tshuaj chlorine dioxide los kho trihalomethanes, tab sis txoj kev no yog kim thiab muaj kev nyab xeeb, yog li ua ntej ntxuav cov dej haus, feem ntau siv cov pa roj carbon monoxide tshem tawm cov pa phem, adsorption ntawm trihalomethanes hauv dej.
Cov pa roj carbon activated muaj lub peev xwm los nqus cov pa phem, nws cov dej huv huv feem ntau tshwm sim hauv cov hauv qab no:
(1) Cov pa roj carbon activated muaj cov nyhuv deodorization, nws tuaj yeem tshem tawm cov roj, phenol thiab lwm yam khoom hauv cov ntxhiab tsw, thiab muaj qee yam adsorption ntawm cov tshuaj no.
(2) Cov pa roj carbon activated muaj cov nyhuv decolorization, nws tuaj yeem tshem cov xim ntawm cov dej los ntawm cov hlau lossis cov nroj tsuag decomposition ntawm cov khoom. Thiab tuaj yeem txo cov xim ntawm cov organic teeb meem, thiaj li tshem tawm cov suab nrov hauv dej.
(3) Cov pa roj carbon activated tuaj yeem tshem tawm trihalomethanes hauv dej. Cov dej qias neeg los ntawm cov kav dej phwj tuaj yuav muaj qee yam ntawm trihalomethanes, uas ua rau muaj kev phom sij rau tib neeg kev nyab xeeb thiab kev noj qab haus huv. Cov pa roj carbon activated tuaj yeem nqus tau trihalomethanes zoo.
(4) Tshem tawm cov pa phem xws li tshuaj tua kab. Tam sim no, lub ntsiab culprit ntawm dej qias neeg yog txhua yam ntawm cov organic tebchaw xws li tshuaj tua kab thiab tshuaj tsw qab, uas tsis tuaj yeem zom tau los ntawm cov kab mob hauv dej thiab ua paug rau cov dej.
(5) Tshem tawm cov hlau hnyav los ntawm dej.
