钢厂除尘废水磁场净化法研究

钢厂除尘废水常用重力沉降或絮凝－沉降法净化。由于尘粒微细，自然沉降缓慢。固体悬浮物具有强磁性，故用复合絮凝－磁滤或絮凝－磁滤净化法能改善固液分离效果。本文在系统研究净化工艺基础上，对磁分离过程的数学模型进行了较详细的探讨。

Study on the Magnetic Field Purification Method for Dust-removing Waste Water of Steel Plants

Dust-removing waste water is commonly purified by gravity settling or flocculation-settling methods.As the dust particles are very fine,the natural settling process is slow.The solid suspended matter has strong magnetism,so the solid-liquid separation effect can be improved by the complex flocculation-mangetic filtering or flocculation-magnetic filtering methods. On the basis of the systematic study of the purification technology,the paper discusses in a detailed way the mathematical model of the magnetic separation process.
