摘　　要：以聚丙烯酰胺改性淀粉作为化学絮凝剂对青海毛纺厂的洗毛废水进行絮凝处理,处理效果十分理想。COD及固体悬浮物去除率分别达95%及97%以上。絮凝污泥以溶剂甲苯进得萃取回收,得羊毛脂。该法工艺简单,综合效益好,有工业推广价值。A graft copolymer of acrylamide on starch was been used as flocculation for treatment of wool washing wastewater, which provided by Qinhai Wool Weave Works. The COD and SS of the waster water can been moved about 95% and 97% respectively. The lanolin can be extracted by toluene from the deposit easily. The method is simple and profit, and should be industrialized.
