| 摘 要： | 采用臭氧氧化法深度处理印染废水二级出水,以比臭氧消耗量为基础讨论出水水质的改善情况.实验结果表明:当比臭氧消耗量为6.5 mg/mg 时,出水的吸光度在400 nm处减少90%以上,在254 nm处减少85%以上;出水的溶解性有机碳质量浓度为11.23 mg/L、COD为16.3 mg/L;臭氧分子直接氧化对降低色度和去除有机物起到一定作用,采用臭氧氧化法深度处理印染废水二级出水在技术上是可行的. |

| Abstract: | The effluent of dyeing wastewater secondary treatment was treated by ozonation process. When the ozone consumption ratio is 6.5 mg/mg, the absorbances of the treated effluent at 400 nm and 254 nm are decreased by 90% and 85%, respectively, and the mass concentration of dissolved organic carbon and COD of the treated effluent are 11.23 mg/L and 16.3 mg/L, respectively. These results indicate that direct oxidation with ozone can play a role on the removal of color and organic matters, and ozonation process is technically feasible for advanced treatment of the effluent of dyeing wastewater secondary treatment. |
| Keywords: | ozone dyeing wastewater secondary treatment effluent ozonation process ozone consumption ratio wastewater advanced treatment |
