In the production process of the chemical industry, a large amount of wastewater with complex components is generated. This wastewater often has a strong color, so decolorizing agents for chemical industrial wastewater have thus become a key element in the wastewater treatment process.
The color of chemical industrial wastewater has a wide range of sources. When producing various chemical products, dyes, intermediates, and some organic compounds with chromophores are all the causes of the wastewater's color. If these colored wastewaters are directly discharged
Decolorizing agents for chemical industrial wastewater achieve decolorization through a variety of action mechanisms. Adsorption-type decolorizing agents, such as activated carbon, utilize their abundant pore structures to efficiently adsorb pigment molecules in the wastewater, gradually fading the color of the wastewater. Flocculation-type decolorizing agents, on the other hand, add chemical agents to promote the mutual aggregation of pigment molecules in the wastewater to form larger flocs, which are then removed by conventional solid-liquid separation methods such as sedimentation or filtration. Oxidation-type decolorizing agents rely on the oxidizing ability of strong oxidants to break the chromophores of pigment molecules, making them lose their coloring ability and thus achieving the purpose of decolorization.
Using decolorizing agents for chemical industrial wastewater has remarkable advantages. It can efficiently and rapidly remove the color of wastewater, enabling the wastewater to meet relevant discharge standards and greatly reducing the risk of environmental pollution. The operation of using decolorizing agents is relatively simple. Just based on the specific characteristics of the wastewater, such as the type and concentration of pigments, etc., reasonably adjusting the dosage of the decolorizing agent and the treatment process can achieve good decolorization effects. In addition, with the continuous development of environmental protection technologies, new types of decolorizing agents for chemical industrial wastewater, while ensuring high-efficiency decolorization, pay more attention to environmental protection performance, reducing secondary pollution to the environment and providing strong support for the sustainable development of the chemical industry.
