摘　　要：进入二十一世纪，能源及环保已成为当今世界可持续发展的两大主题。鉴于我国水资源日趋紧张及水污染的严重形势，污水处理及回用迫在眉睫。钢铁工业作为国民经济各行业中的用水大户，其污水的处理及回用意义尤为重要。新建的首钢京唐钢铁联合有限责任公司采用国际先进工艺装备，建设规模为年产钢坯970万t。钢材品种全部为板材产品。生产流程为原料、焦化、烧结、球团、炼铁、炼钢、连铸、热轧、冷轧的长流程生产工艺。公辅生产工艺遵循循环经济的理念，延长生产过程中水的使用周期，实施生产污水资源化。结合首钢污水治理工程的实践经验以及对新建首钢京唐钢铁厂污水水质的设计，对京唐钢铁厂生产污水采用新型、改进的沉淀、过滤的物理一化学处理工艺，对水中的油、悬浮物、硬度、碱度等有害物质进行有效去除，节约全厂工业新水耗量，提高全厂经济和环境效益。污水处理站进水经处理后最终全部回用。In the 21st century, resource and environmental protection have been become two big subjects of sustainable development in the modern world. Based on the present severe situation of the water shortage and water pollution waste water treatment and recycling are urgent. Iron and steel industry is the big water user. The industrial waste water treatment is especially important. New SGJT adopted international advanced technics and equipment with production of 9.7 million tons billets every year. All products are plate. The production process contains raw material, coking, sintering, pelletizing, iron -making, steel -making, continuous casting, hot rolling, cold rolling. FoUowing circulation economy theory, lengthening in duration the water cycle period and reusing the waste water. Combination with practical experiences and the design of waste water of SGJT united iron and steel co. , Ltd. , we adopt new and improved deposition, filtration physical - chemical technology to get rid of the poisonous matter such as oil, suspended matter, rigidity and alkality. By this way we can save water usage and improve economic benefit and environmental benefit. The waste water can be reused after treating at the waste water treatment station.
