O_3氧化处理染料废水的试验研究

Ozone Oxidation Test for Treating Dyeing Wastewater

Ｏ３是一种强氧化剂。利用臭氧处理带色有机废水。可以脱色，而且可以降低废水ＣＯＤ。采用Ｏ３氧化脱色速度快，效果好，对废水的脱色率可达８０％以上，这是通常的混凝处理难以达到的。如果采用通臭氧和混凝联合处理，处理效果会更好，脱色率可提高到９５％以上。

Ozone is a strong oxidant. Treating the colored organic wastewater by ozonation can effictively decolorize it and reduce COD of the wastewater.It has been observed that its removal ratio of color can be up to or over 80% ,but usual chemical coagulation can not achieve this. If ozonation is conjuncted with chemical coagulation ,an higher efficieney can be obtained, its removal ratio of color can be up or over to 95%.
