印花彩钢板生产中的脱脂废水如何处理

印花彩钢板生产中，脱脂废水首要来源于出产流水线中卷板水洗部分和卷板外表预处理。废水要做好相应的处理后才能够排放，否则可能会造成环境污染。那么对于印花彩钢板生产中产生的脱脂废水应该如何处理呢：

1、印花彩钢板酸化方法：用盐酸或硫酸作分离剂，将PH值调整到2.0~2.5，静置数小时后溢流分离；
　　2、 印花彩钢板加热法：升温至80℃以上，并保温2~3小时，冷却后分离；
　　3、 印花彩钢板分离器法：选择专用的油水分离器进行分离操作。
　　以上介绍的几种方法，可以根据废水的多少以及设备来选择合适的处理方法，但是记住：废水一定要处理过后再排放，否则会破坏我们的生存环境。

In the printing color steel plate production, the degreasing waste water mainly comes from the water washing part of the rolling plate and the surface pretreatment of the rolling plate in the production line. Waste water can only be discharged after corresponding treatment, otherwise it may cause environmental pollution. How to deal with the degreasing wastewater produced in the production of printing color steel plate

1. Acidizing method: hydrochloric acid or sulfuric acid was used as the separating agent, the pH value was adjusted to 2.0 ~ 2.5, and the overflow was separated after standing for several hours;
2. Heating method: raise the temperature above 80 ℃, keep the temperature for 2-3 hours, and separate after cooling;
3. Separator method: select special oil-water separator for separation operation.
The above methods can be selected according to the number of wastewater and equipment, but remember: wastewater must be treated and then discharged, otherwise it will damage our living environment.
