Abstract

Dyeing wastewater was difficult to treat due to its high concentration of organic matter,high chroma,complex component,etc.The technique of flocculation and two-stage hydrolytic acidification-biological contact oxidation was used to process the high strength dyeing wastewater from some dyeing company in Nantong.The treatment system was stable and excellent with a capacity of sewage drainage about 600 m3/d.The sewage drainage can meet the class III of National Wastewater Discharge Standard(GB8978-1996).The results of treatment technology showed that it had two advantages of high running stability and excellent treatment effect.
