不锈钢冷轧含酸含油废水处理技术

The Treatment Technology of Oily and Acidic Wastewater from Cold-rolled Stainless Steel Production

介绍了不锈钢冷轧厂的含酸、含油废水处理的工艺技术,以及运行中的过程控制。通过熟石灰中和-絮凝沉淀的方法可以有效除去重金属离子;超滤能去除废水中的大部分悬浮油,DCS系统有助于实现精细化管理,控制成本。结合现场运行数据,本文为冷轧废水处理项目的稳定、经济运行提供参考。

The treatment technology of oily and acidic wastewater from cold - rolled stainless steel production and the procedure control in operation were introduced. Heavy metal ion can be removed effectively by hydrated lime neutralization and flocculation. Dislodging emulsifying oil from the effluent by ultrafiltration membrane was very effective. Applying the DCS system was conduce to fine management. By analyzing the data from actual operation, it provided reference for the steady and economic operation in wastewater treatment project.
