This paper briefly introduces the character and present treatment of dyeing wastewater. The synthetic way and chemical modifing methods of synthetic organic polymeric flocculant and its application to dyeing wastewater treatment are especially reviewed, inducing the mechanism of flocculation. This paper also reviews the progress of research and application of natural polymetic flocculant including lignin, chitosan and modified starch flocculant, pointing out that organic polymeric flocculant is a kind of effective flocculating decolorant and the trend of its research and development is forecast.
