腈纶织物染色废水的污染物分析

Analysis of the pollutants in acrylic fabric dyeing wastewater

采用腈纶织物实际染色工艺,收集各阶段试验废水并进行分析.研究结果表明,腈纶染色废水的CODCr主要由各种难降解的助剂组成,而色度主要由残余阳离子染料造成.

Effluents were collected for analyses from various steps in practical dyeing recipes and processes of acrylic textiles, The wastewater CODCr is mainly composed of the difficult degraded products of the auxiliaries, and the colors are mainly composed of the residual cationic dyes.
