热轧车间浊环水的处理

介绍了热轧车间浊环水因含有润滑油脂、氧化铁皮、泥砂等杂质，如采用传统的三段式处理工艺，除油效果差，长期运行易堵塞管道、冷却塔、过滤器等设备。现采用新型的二段式水处理工艺，应用高效磁混凝沉淀、化学除油等技术，简化了处理流程，具有投资省、占地小、管理维修方便等优点，并通过生产实践运行取得了良好的处理效果，满足了用户对水质的要求。

Treatment for the turbid circulating water in hot-rolled workshop

This thesis introduces that turbid circulating water in hot - rolled workshop contains impurity such as grease lubricant, oxidized iron sheet and silt etc. and the traditional three-stage water treatment process always fails to remove the oil efficiently, so the pipe, cooling tower and filter tend to be blocked up after long-time operation. The application of newly developed two-stage water treatment process and the techniques such as high-efficiency magnetic concrete precipitation and chemical oil removing in simplifies the treatment process and brings the advantages of less investment, space-saving and convenient management and maintenance. The good results in water treatment have been obtained through practical production and the users' requirements for water quality have been satisfied.
