Daim ntawv thov txheej xwm ntawm activated alumina hauv kev kho dej. Hauv kev kho dej, activated alumina yog siv los adsorb qee lossis ntau cov pa phem hauv cov dej khib nyiab kom rov qab los yog tshem tawm, thiaj li ua kom huv cov dej pov tseg. Siv nws lub peev xwm adsorption rau cov khoom sib cais muaj keeb kwm ntev. Cov kws tshawb fawb tshawb fawb hauv tsev thiab txawv teb chaws tau ua ntau txoj haujlwm tshawb fawb hauv daim teb no. Tam sim no, activated alumina adsorbent tau siv dav hauv kev lag luam tshuaj, kev tiv thaiv ib puag ncig, tshuaj thiab kev noj qab haus huv, bioengineering thiab lwm yam. Nyob rau hauv cov nqe lus ntawm kev lag luam tshuaj thiab kev tiv thaiv ib puag ncig, activated alumina feem ntau yog siv los ntxuav cov pa khib nyiab, rov qab cov kuab tshuaj (tshwj xeeb tshaj yog chlorinated hydrocarbons, reactive solvents thiab boiling point solvents) thiab tshem tawm cov kuab paug los ntawm dej. Daim ntawv thov Scope ntawm tom kawg suav nrog decolorization, deodorization, tshem tawm cov hlau hnyav, tshem tawm ntau yam yaj cov organic teeb meem thiab cov khoom siv hluav taws xob. Nyob rau hauv txoj kev kho mob, activated alumina yuav siv tau raws li pretreatment ntawm ion pauv, membrane sib cais thiab lwm yam kev tshem tawm cov organic teeb meem, colloid thiab residual chlorine. Nws tseem tuaj yeem siv los ua kev kho mob siab heev txhais tau tias tom qab kev kho mob thib ob los xyuas kom meej cov dej rov qab zoo. Siv cov txheej txheem adsorption rau kev kho dej muaj qhov zoo ntawm daim ntawv thov dav, cov nyhuv kho tau zoo, cov ntaub ntawv siv tau zoo thiab rov siv tau cov adsorbents. Nrog rau kev txhim kho txuas ntxiv ntawm kev ua haujlwm ntawm cov khoom siv alumina uas twb muaj lawm thiab kev txhim kho zoo ntawm cov adsorbents tshiab, daim ntawv thov kev cia siab ntawm activated alumina hauv kev kho dej yuav dav dua.
Activated alumina adsorbent yog qhov tseem ceeb los txiav txim siab cov txheej txheem kev ua haujlwm siab adsorption. Hauv kev txiav txim siab dav dav, tag nrho cov khib nyiab muaj peev xwm adsorption, tab sis tsuas yog cov khoom ntxeem tau lossis cov ntaub ntawv hauv av zoo muaj thaj tsam loj. Industrial adsorbents yuav tsum tau ua raws li cov hauv qab no:
1. Muaj peev xwm adsorption muaj zog;
2. Zoo adsorption selectivity;
3. Tsawg adsorption equilibrium concentration;
4. Yooj yim rov tsim dua thiab rov siv dua;
5. Zoo mechanical zog;
6. Cov khoom siv tshuaj ruaj khov;
Nws yog ib qho nyuaj rau kev lag luam adsorbents kom tau raws li rau qhov yuav tsum tau ua nyob rau tib lub sijhawm. Yog li ntawd, sib txawv adsorbents yuav tsum raug xaiv raws li ntau zaus hauv cov txheej txheem ntawm kev kho adsorption. Tam sim no, cov adsorbents uas tuaj yeem siv rau kev kho dej muaj xws li activated carbon, activated alumina, modified starch adsorbent, modified cellulose adsorbent, modified lignin adsorbent, modified chitosan adsorbent and other agents and material that can absorbs pollutants.
