| 中文摘要 |
| 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。 |
| 英文摘要 |
| Following the idea of reversible chemical complexation,a study on thermodynamic equilibrium and cross-current flow extaction of various industrial phenolic effluents has been carried out. The new mixed solvents (QH) for this purpose have been developed. The results show that by using this treatment technique the raff mates of phenolic effluents can comply with the required disposalstandard through only 2—3 stages of cross-current flow extraction. This treatment technique has been used successfully. |
