技术简介

染色残液的处理过程中形成了水+盐(水相)和萃取剂(油相)两个体系的闭环循环，在萃取装置中相互作用，连续地将染色残浴中的水解染料提取出来，高盐浓液则循环使用。

Introduction

The treatment of dye residues creates a closed-loop cycle of two systems, water + salt (aqueous phase) andextractant loil phase), which interact with each other in the extraction unit to continyously extract the hydrolvzeddve from the dye residue bath, while the high-salt concentrate is recycled.
