摘要
采用络合萃取法处理CLT酸酸析废水。考察了萃取剂浓度、相比、萃取反应时间等因素对CLT酸废水CODcr去除率的影响。结果表明,在适宜工艺条件下,经一级萃取废水CODcr去除率达96%以上,出水CODcr低于2000mg/L。
The complexation extraction process was adopted to treat CLT acid waste water. The effects of solvent concentration, phase ratio, extraction time, on the CODcr removal efficiency of CLT acid waste water were investigated in this test. The experimental results indicated that under the (appropriate) conditions, the CODcr removal efficiency was more than 96%, and the residual COD of the flux water was less than 2 000 mg/L,after one-stage extraction treatment.
