1. Introduction
Considerable amount of high quality water is
needed for textile industry for dyeing and finishing
operations. Color and recalcitrant compounds
are among the vital environmental
concerns in effluent treatment. Wastewater from
these industries represents a variety of pollutants,
high strength load and high in color depending
on the stage of the process and nature of discharge.
The high pollution load is generated from
spent dyeing baths, first and second rinses carried
out after dyeing processes. These effluents consist
of unbound colorants or reaction products,
which remain in the substrate and are washed
out in subsequent rinses, dye impurities, auxiliaries
and surfactants. These compounds exhibit
slow degradation kinetics for conventional

1。简介
在纺织工业的染色和最后处理过程中需要大量高质量水。颜色和难分解物是是涉及到流出水处理中至关重要的环境问题。从这些工业中排出的废水带来了很多污染，高负荷和高含量的颜色取决于对废水处理阶段和排出物本身特性。高负荷污染是在染色过程后对染料进行的一二次清洗中产生的。这些排出物由未分解的着色剂或其反应生成物组成，这些反应生成物保留在着色剂表面，随后通过冲洗，染料杂质？，辅助手段或加表面活化剂等方法洗掉。 这些混合物通常呈现一种缓慢的分解运动。
