臭氧发生器（Ozonizer） The ozone oxidation of dyeing wastewater is difficult to decompose organic matter degradation Ozone is currently recognized as a green oxidant, has a variety of functions, especially to improve the degradation of organic matter biodegradation degree. The mechanism is that the ozone oxidation of atomic energy group into processing material, change the molecular structure and the performance of the original material, so as to improve the degree of biodegradation. Dyeing wastewater contains a variety of refractory organic compounds, ozone oxidation technology of biological pretreatment and high concentration organic wastewater, from the theoretical analysis, feasible such as other industries (such as pesticide factory, chemical factory, pharmaceutical factory, coking plant, etc.) have similar uses, the application research is also in progress. Dye color is caused by the chromophoric groups such as vinyl, azo, azoxy radical, hydroxyl, thione, nitroso, vinylene. Are these chromophore unsaturated bonds, these groups can make the ozone oxidation dye containing decomposition of organic acids and aldehydes to generate molecular the smaller amount, which lost its ability of hair color. Therefore, ozone as oxidant and good decolorizing agent. Fundamentally speaking, the principle is ozone and ozone decolorization occurred active radicals (OH dyes unsaturated bond cleavage, the chromophore in order to change the original molecular structure and chemical properties, to achieve ozone decolorization and degradation of organic dyes on various function results is different, the hydrophilic dye fast and good effect; the hydrophobic dye decolorization of slow speed and bad effect. Bleaching and dyeing wastewater by ozone pretreatment technology, improve the refractory organics biodegradation, and the removal of most of the biochemical colorimetry, the subsequent disposal to achieve the best effect. Biological wastewater treatment in refractory wastewater, various compo
