摘　　要：本文采取络合萃取—生物接触氧化技术处理活性染料工业废水。考察了萃取剂种类、浓度、相比及废水pH值等因素对该废水去除效率的影响。结果表明,活性染料废水经过预处理后,CODCr去除率大于90%,处理后废水经进一步生化处理可达标排放。The technology of complex extraction-biological contact oxidation to treat reactive dye industrial wastewater was investigated.The effects of types and concentration of extractant,ratio of oil to water and the pH value of wastewater on the removal efficiency were studied.The results showed that the removal rate of CODCr of the pretreated reactive dye wastewater was higher than 90%,and the treated wastewater could meet the emission standard by further biological treatment.
