Abstract
Dye waste-water is one of the main sources of water environmental pollution, which belongs to the characteristics of refractory organic waste-water with large chroma, high concentration, large water quality difference, complex composition and large history of pH change. Physical, chemical and biological methods are the main methods on the treatment of dyeing waste-water. The advanced oxidation technology based on hydroxyl radical (•OH) has the advantages of strong oxidation, low selectivity and high elector-philicity. There are mainly seven ways to produce hydroxyl radical (•OH): Fenton oxidation, photo-catalytic oxidation, ozone oxidation, electrocute-chemical oxidation, ultrasonic oxidation, wet oxidation and super-critical water oxidation. These methods have significant effect on dyeing waste-water treatment.
