摘要
本试验研究了采用络合萃取法回收 2 ,3 -酸生产废水中染料中间体的多种影响因素。试验表明通过萃取工艺处理 2 ,3 -酸生产废水是可行的 ,一级萃取出水CODcr在 10 0～ 2 0 0mg/L ,萃取率可达
The affecting factors were examined in the research on recovery of dye intermediates from 2,3 Acid wastewater by the complexation extraction process.The experimental results showed that the complexation extraction was feasible to treat 2,3 Acid wastewater,COD cr could be dropped to 100～200mg/L with 96% of removal rate.
