摘要
研制的一种新型脱色絮凝剂－双氰胺－甲醛阳离子聚合物，对染料废水和印染废水的脱色絮凝效果较好，脱色率均可达９０％以上，ＣＯＤ去除率可达６７％，如与硅藻土复配使用，效果更佳．另外，本文还对脱色絮凝机理进行了探讨．
The synthesis of a new decolorizing flocculant-the cationic polymer of dicyanodiamide-HCHO is represented by this paper. The results of its treatment on dyeing and printing wastewater are satisfactory, that the decolour rate is above 90% and the rate of COD decreases 67%. The result is improving upon the use of diatomaceous earth togather. Also, the decolorization mechanism has been studied.
