Kev lag luam pov tseg roj purification feem ntau yog hais txog kev kho cov khoom siv khib nyiab xws li cov plua plav, pa taws, tsw ntxhiab, cov pa phem thiab cov pa phem uas tsim tawm hauv cov chaw ua haujlwm.
Cov pa khib nyiab tawm los ntawm kev tsim khoom lag luam feem ntau muaj kev phom sij rau ib puag ncig thiab tib neeg kev noj qab haus huv.Purify ntsuas yuav tsum tau ua ua ntej tso pa tawm raws li cov kev cai ntawm cov pa emission qauv.Cov txheej txheem no yog hu ua khib nyiab purification.
Adsorption txoj kev siv adsorbent (activated carbon, molecular sieve, purification desiccant) rau adsorb pa phem nyob rau hauv industrial tso pa roj, thiab qhov tsim nyog adsorbent yog xaiv rau txawv pa roj Cheebtsam.Thaum cov adsorbent ncav cuag saturation, cov pa phem raug tshem tawm, thiab cov tshuab catalytic combustion yog siv los ua kom oxidize cov organic teeb meem rau carbon dioxide thiab dej hauv cov khoom siv khib nyiab, yog li ua tiav tag nrho-hauv-ib lub tshuab thiab cov cuab yeej pabcuam rau kev huv. lub hom phiaj.
