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
