Cov dej khib nyiab yog qhov nyuaj thiab nyuaj rau kev kho.Cov kev kho mob feem ntau suav nrog oxidation, adsorption, membrane sib cais, flocculation, biodegradation, thiab lwm yam.
Cov txheej txheem no muaj qhov zoo thiab qhov tsis zoo, qhov twg cov pa roj carbon activated tuaj yeem tshem tawm cov chroosity thiab COD ntawm cov dej khib nyiab Active carbon adsorption feem ntau yog siv rau kev kho mob sib sib zog nqus los yog siv cov pa roj carbon activated ua cov cab kuj thiab catalyst, thiab qee qhov kev tshawb fawb siv cov pa roj carbon activated los kho cov dej khib nyiab siab ib leeg. .
Cov pa roj carbon activated muaj qhov cuam tshuam zoo rau cov dej khib nyiab.Lub discoloration tus nqi ntawm dye dej khib nyiab nce nrog nce kub thiab pH tsis cuam tshuam cov nyhuv ntawm cov dej khib nyiab.
