Abstract:

A series of experiments about the treatment of concentrated banknote printing wastewater without adding acid is carried on.The results show that good effect can be obtained without adding acid.If S-1018is used,the COD_Crin the wastewater is lower than2000mg /L and the range of pH is6to7.So it lays a foundation for the wastswater treatment to come up to the discharge standards.

Key words: banknote printing wastewater, water treatment, coagulation

摘要：

对高浓度印钞凹印废水进行了一系列的非加酸工艺的处理试验。结果表明,完全可以采用非加酸工艺达到理想的处理效果。当投加S-1018系列处理剂后,出水pH控制在6～7,COD_Cr控制在<2000mg/L的范围内,为该废水治理达标排放奠定了基础。
