摘要
用络合萃取法处理活性红M 3BE废水母液 ,COD去除率可以达到 71.4% ,经絮凝处理 ,COD总去除率达 97.3 % ,回收产品质量达到企业标准 .萃取剂经过循环使用 ,萃取效果并没有下降 .文中同时讨论了影响萃取和絮凝效果的一些因素 .
Wastewater from the production of Reactive Brilliant Red M 3BE is treated by applying extraction and flocculation. Removal rate of COD of wastewater is above 97%. The extract is back washed with sodium hydroxide solution (20%) to recover Reactive Brilliant Red M 3BE.The extracting efficiency does not decrease even after being reused for 20 times. This paper also discusses certain factors that affect extracting and flocculating efficiency.
