Cov nyhuv decolorization ntawm cov carbon ua kom muaj zog tshaj hauv dej thiab tsis muaj zog hauv cov kuab tshuaj organic.

(1) Kev siv ntsuas kub ntawm cov pa roj carbon kom ua huaj vam yog 70-80 degrees yog qhov zoo dua;

(2) cov nyhuv decolorization ntawm cov carbon ua kom muaj zog tshaj plaws, thiab cov nyhuv kuj yog qhov zoo hauv cov kuab tshuaj muaj zog, thiab cov txiaj ntsig tsis zoo hauv cov kuab tsis zoo;

(3) Raws li qhov xwm txheej ib txwm muaj, nws yog qhov zoo dua los siv nyob rau hauv PH3 ~ ph6 cov kev cai;

(4) lub sijhawm decolorization feem ntau yog 30-80min;

(5) Muaj ntau hom thiab cov qauv ntawm cov carbon ua haujlwm, xws li cov roj carbon ua kom piam, roj carbon, thiab lwm yam, los xaiv cov pa roj carbon uas haum.

(6) Tom qab tag nrho stirring thiab adsorption, kev siv ntawm preated preated nqus av txheej, thiab tom qab ntawd pom kev ua kua, tuaj yeem tau txais cov kua txaus siab.
