摘　　要：采用氢氧化镁、壳聚糖、氢氧化镁-壳聚糖复合絮凝剂对皮革染色废水进行脱色处理,研究了pH值、壳聚糖投加量等对脱色效果的影响。结果表明氢氧化镁-壳聚糖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。The decoloration properties of magnesium hydroxide, chitosan and magnesium hydroxide- ehitosan complex flocculant for leather dyeing wastewater are discussed. The effects of pH value and ehitosan dosage on decoloring efficiency are investigated. The results show that magnesium hydroxide- chitosan complex floceulant is superior to magnesium hydroxide or chitosan on decolorization.
