Abstract:

The decolorization mechanism of hig hly efficient decoloring flocculant(HEDF)applied in the treatment ofeffluent from dyestuff printing and dyeing works is discussed in this paper.The application result s of HEDF in laboratories and indust rial production are int roduced.The COD removal rate of i t is 50 % ～ 90 % and the chromaticity removal rate is 80 %～ 99.9 %.

Key words: dye, wastewater of printing and dyeing, decolorization mechanism

摘要：

对高效脱色絮凝剂应用于染料、印染工业废水脱色絮凝处理的机理进行了探讨;从物质的结构和基团反应分析类比了脱色剂的化学、物理作用并以实验为佐证。详细介绍了高效脱色絮凝剂在试验室和工业生产中的应用试验结果。高效脱色絮凝剂对公认难以处理的高浓度、高色度染料、染色等工业废水具有脱色和降低COD作用,COD去除率为50%～90%,色度去除率为80%～999%。
