摘　　要：采用复合絮凝剂对印染废水进行脱色处理,研究了pH值、投加量等对脱色效果的影响。结果表明使用复合絮凝剂比单独使用氢氧化镁或壳聚糖絮凝剂脱色效果好,与铝系絮凝剂的脱色效果相当。The decoloration property of complex flocculant for dyeing wastewater is discussed. The effect of pH value and the added vol- ume of the complex flocculant on decoloring efficiency is investigated. The result shows that the decolorization by use of complex flocculant is better than by use of flocculants alone or magnesium hydroxide chitosan flocculant, and similar to the use of aluminum salts.
