Peb Cov Khoom Tseem Ceeb ntawm Decolorization Cov Khoom

Decolorization cov khoom tau muab faib ua peb pawg tseem ceeb raws li lub hauv paus ntsiab lus ntawm decolorization:

1. Flocculating decolorizer, quaternary amine cationic polymer compound uas ua ke decolorization, flocculation thiab COD degradation hauv ib yam khoom.Los ntawm chemically reacting nrog molecules ntawm colour-forming pab pawg xws li dyestuffs, cov colour-forming pab pawg neeg raug puas tsuaj.Nyob rau tib lub sijhawm, nws tuaj yeem ua rau lub cev muaj zog xws li adsorption thiab bridging yog tsim nrog cov xim-forming molecules, yog li flocculating thiab daws cov xim xim.Cov reacted molecules no yog cov organic, yog li tus neeg sawv cev decoloring tuaj yeem ua tiav lub hom phiaj ntawm kev txo qis COD thiab decolorization.

2. Oxidizing decolorizer, siv cov tshuaj oxidizing, xws li sodium chlorate, poov tshuaj permanganate, ozone, thiab lwm yam., txhawm rau rhuav tshem cov xim xim kom ua tiav lub hom phiaj ntawm kev tshem tawm cov xim.

3. Adsorption type decolorizer, piv txwv li activated carbon, dawb av nplaum los yog adsorption resin, uas tuaj yeem siv los lim tawm impurities thiab oxides hauv cov roj ncaj qha los ntawm kev pom.Lawv ua ke ua haujlwm ntawm kev tshem tawm impurity, tshem tawm tsw, decolorization thiab sib cais, tig cov roj blackened mus rau hauv lub teeb xim thiab pob tshab kua, thiab cov kua qaub thiab xim ntawm cov roj diesel ua tau raws li lub teb chaws cov qauv roj.
