Dyeing wastewater was difficult to treat due to its high concentration of organic matter, high chroma, com- plex 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 ma/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 advan- tages of high running stability and excellent treatment effect.
