摘　　要：冷轧含油废水的处理,对于钢铁企业减少污水排放量和新水用量、提高废水循环利用率具有重要的意义。介绍了国内外常用的冷轧含油废水处理技术,如重力分离法、气浮法、絮凝法、吸附法、膜分离法、生物法、膜生物反应器等,描述了冷轧含油废水处理工艺与现状,展望了冷轧含油废水处理的发展趋势。For iron and steel enterprises, the treatment of oil-bearing wastewater from cold rolling has great signifi- cance to reducing the amount of effluent discharge and the dosage of fresh water needed, and improving the cyclic utilization water of wastewater. The commonly used treatment technologies of oil-bearing wastewater from cold roiling in China and abroad, such as gravity separation, air flotation, flocculation, adsorption, membrane separation, biolog- ical method and membrane bioreactors are introduced. In addition,the treatment process and present status of oil- bearing wastewater from cold rolling are described. Furthermore, the developing trend of oil-bearing wastewater from cold rolling is forecast.
