摘要：

洗毛生产线二、三洗槽高浓度洗毛废水,经混凝处理后,COD去除率在 98%以上,水质清澈透明,予以回用,实现闭路循环。经混凝沉淀后的污泥,通过物理或化学处理,每吨洗毛废水可回收羊毛脂 0.7～ 1.2kg,达到了环境与经济效益同步的目的。

关键词: 洗毛废水, 混凝, 资源回用

Abstract:

The paper introduces the treatment of wool scoring wastewater, using coagulating technology to purify high concentration effluent in the second and third scoring dales of the manufacturing line and the COD removal rate is above 99%. Purified water is very clear and can be recycled. The sludge which has been coagulated and deposited can be abstracted 0. 7~ 1. 2 kg lanolin from a ton of wastewater by physical or chemical treatment.Both environment protection value and economic effect are achieved.

Key words: wool scoring effluent, coagulation, natural resources recovery
