Explanation

All substances that can remove the color that affects the appearance of the product are collectively referred to as decolorant. Commonly used in wastewater treatment, diesel processing, food processing industries, such as textile, printing and dyeing, ink, leather, rubber, coking, paper making, pharmaceutical and other wastewater decolorization treatment. decolorant can be roughly divided into the following H categories according to the decolorization principle: ① flocculating decolorant. Quaternary amine cationic macromolecule compound integrating decolorization, flocculation, degradation and other functions. ② Adsorption of decolorant. Generally, activated carbon, clay or adsorption resin can directly filter impurities and oxides in the oil by means of filtration, which integrates impurity removal, odor removal, decolorization and separation, so that the blackened oil can become a light and transparent liquid. The acid value and chroma of processed diesel meet the national fuel standards. ③ Oxidizing decolorant. Using oxidizing substances such as sodium chlorate, potassium permanganate, ozone, etc? Destroy the colored groups to achieve the purpose of removing chromaticity.
