摘　　要：以动植物提取物、微生物、矿物及其提取物和环境废物作为环境友好絮凝剂,具有无毒、易生物降解、无二次污染或可以废治废和环境友好等优点,但存在对实际废水适应性差和使用条件严格等问题。本文简述了环境友好絮凝剂来源、有效成分和作用机理,介绍了近年来环境友好絮凝剂在印染废水处理中的应用现状,讨论了p H、投加量、废水中染料特性和投加方式对絮凝效果的影响,为印染废水处理中环境友好絮凝剂的选择、应用和研发提供了关键参数。同时指出环境友好絮凝剂在印染废水处理中的应用受限于其有效成分和制备成本,为环境友好絮凝剂的工业化应用提出了挑战。最后提出接枝改性、无机-有机复配和杂化以及改进提取和制备方法有望提高环境友好絮凝剂的效果,解决环境友好絮凝剂在印染废水处理中的适应性和广谱性问题。The environment friendly flocculant includes animal extracts,plant extracts,microorganism,mineral extracts and environmental waste,has the advantages of non-toxic,biodegradable,no secondary pollution or environmental friendly. In this paper,the sources,the effective components and the working mechanisms of environment friendly flocculants were introduced. The current application statue of environment friendly flocculant in the treatment of printing and dyeing wastewater were discussed. The focus was on the influence of p H,dosage,dye characteristics and dosing mode on the effluent quality. Some key parameters were provided for the selection,application and development of environmental friendly flocculants. Lower active components and higher preparation cost are pointed out to restrict its industrial application. Finally,grafting modification,inorganic-organic hybrid,exploring more effective preparation methods were recommended to enhance the adaptability of environment friendly flocculent in the treatment of the printing and dyeing wastewater.
