Progress of organic polymer flocculant applied to dyeing wastewater treatment

简要介绍了印染废水的水质特点和处理现状,着重综述了各类人工合成有机高分子絮凝剂的合成途径、化学改性方法及其在印染废水处理中的应用进展,并对其絮凝机理进行了归纳。文章还综述了木质素、壳聚糖、改性淀粉等天然高分子絮凝剂的研制及应用进展。指出有机高分子絮凝剂是一类有效的絮凝脱色剂,对有机高分子絮凝剂的研究和应用趋势作了展望。

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.
