摘要
某化纤厂排放的二甲基亚砜废水不但恶臭大,而且COD值高,现有处理工艺由于引入大量新的污染物氯离子,且水中需保持较高的余氯,对后续生化系统影响较大。本文研究了多元催化氧化对该废水的处理效果,实验表明,经过多元催化氧化装置,废水中的COD值去除率在62%以上,且可生化性(B/C比)由0.18提高到了0.38,为后续进一步生化降解奠定了很好的基础。
DMSO wastewater in a chemical fiber plant discharge not only smell unpleasant, and the COD vdue is high, the existing treatment process effects the subsequent biochemical systems more due to the introduction of new pollutants chloride ions, and water required to maintain a high residual chlorine. In this paper, the wastewater treatment effect by multiple element catalytic oxidation are studied, the rusult shows,after multiple catalytic oxidation unit, the COD removal rate of wastewater over 62%, and biode- gradability (B/C) ratio increased from 0.18 to 0.38 ,it laid a good foundation for subsequent biodegradation.
