| 摘 要： | 设计了高效ＱＨ型络合萃取脱酚溶剂，建立了工业含酚废水络合萃取工艺，进行了不同种类含酚废水的络合萃取平衡和错流萃取的实验。结果表明，利用ＱＨ混合型络合萃取剂，通过２－３级错流接触（油水比为１：１），废水残液中的酚类浓度小于０．５ｍｇ／Ｌ，可以达到国家规定的排放标准。初步研究表明，该法对废水中ＣＯＤ亦有较好的去除效果。

| Abstract: | Following the idea of reversible chemical complexation,a study on thermodynamic equilibriumand cross-current flow extaction of various industrial phenolic effluents has been carried out. Thenew mixed solvents (QH) for this purpose havebeen developed. The results show that by usingthis treatment technique the raff mates of phenoliceffluents can comply with the required disposalstandard through only 2-3 stages of cross-current flow extraction. This treatment techniquehas been used successfully. |
