Abstract:
The water quality characteristics of the wastewater treatment process, treatment technology, main constructions and technical parameters at a banknote-printing factory in Shijiazhuang are introduced.Some suggestions for improvement on blasting aeration and the blower noise, and sludge discharge are recommended.It is proved that the treatment process of “coagulation floatation + biological contact oxidation + sand filtration”for treating integrated banknote-printing wastewater has good results, and the outgoing water quality meetes the requirement of the First Class Standard of Integrated Wastewater Discharge GB 8978—1996.
