摘　　要：介绍了以毛纺厂废毛为主要原料的絮凝脱色剂WY的制备方法及絮凝脱色机理,并对其在酸性染料普拉红2B染色废水脱色处理中的应用效果进行了试验分析。结果表明,絮凝脱色剂WY单独使用时的脱色率可达96%以上,与少量聚丙烯酰胺助凝剂或聚合铝铁混合使用时,脱色率最大可达99%左右,同时可以明显提高沉降速度。Preparation and mechanism of the flocculants WY made from the waste wool of woolen mills were introduced. Its application to acid dyestuff wastewater treatment was analyzed. The results showed that decolorization rate reached over 96% when flocculants WY used alone, and up to 99% when mixed with a small amount of polyacrylamide coagulant or polymer ferric, and increased the settling velocity also.
