Wastewater Decolorizer is a kind of treatment agent mainly used in industrial wastewater. It is aimed at the colored group components in wastewater. It is a water treatment agent that reduces or removes the chroma in wastewater to achieve an ideal state. According to the principle of decolorization, decolorizers can be generally divided into three categories: flocculation decolorizers, oxidation decolorizers and adsorption decolorizers. Oxidative decolorizing agent mainly uses its strong oxidizing property to destroy the colored groups to achieve the purpose of removing chroma, while adsorption decolorizing agent removes chroma through its own pore adsorption. These two methods have many limitations and disadvantages and are not suitable for large-scale It is used in a wide range, which makes the flocculation decolorizer the mainstream product of decolorization.

The decolorizer can also demulsify the surfactant and emulsified oil contained in the wastewater through the principle of flocculation and precipitation, and electrolyze it into small particles, and then sink under the action of gravity through flocculation and precipitation to achieve solid-liquid separation. process. Its purpose is to remove suspended organic matter, reduce COD in water, remove chroma, and at the same time achieve multiple functions of reducing the organic load of subsequent biochemical treatment.

The operation method of wastewater decolorizer is also relatively simple: first take 100ML of wastewater for treatment experiment, then add 2.5 parts per thousand of Beijingshi wastewater decolorizer to the wastewater, stir for 6-8s, then adjust the pH value to 7-8, and finally add an appropriate amount The precipitation of PAM anion (1‰ aqueous solution) completes the treatment.

The wastewater decolorizer is mainly used in the decolorization treatment of high-chroma wastewater in dye factories, and can be applied to the wastewater treatment of reactive, acidic and disperse dyes. It can also be used for textile, bleaching and dyeing, printing and dyeing wastewater treatment, and industrial wastewater treatment of pigments, inks, and papermaking.
