摘要
印染、纺织、食品、造纸及皮革等相关行业的发展所带来的水污染问题由来已久,工业的迅速发展导致污染问题的日益严重,传统的废水处理方法和常用处理材料已不能满足目前高效、无毒害、低成本等处理染料废水的要求。其中,因阳离子染料废水成分复杂、处理难度高,引发了研究者的广泛关注。文中主要介绍了近几年对常用废水处理材料的改性方法、传统方法与新工艺的结合,以及某些纳米材料、纳米技术在染料废水处理方面的应用潜力和前景,比较分析了各种处理方法及材料的优缺点。综合近年文献发现,对传统吸附剂进行改性处理或将传统处理方法与新材料相结合,是一种行之有效的提高染料废水处理效率的方案。
The development of dyeing,textile,food,paper,leather and other related industries has brought serious water pollution problems for a long time.The rapid development of industry leads to the increasingly serious problem of pollution,and the traditional methods of wastewater treatment and common materials cannot meet the requirements of high efficiency,non-toxic,low-cost and others.The complex composition of cationic dye wastewater and the difficulty of treatment has caused widespread concern of researchers.This paper mainly introduces the modification methods of common materials for wastewater treatment,the combination of traditional methods and new technique in recent years,as well as the application potential and prospects of nano materials and nano technologies in dye wastewater treatment.A comparative analysis between the advantages and disadvantage of various treatment methods and materials are also given.It has been found that the modification of traditional adsorbents or the combination of traditional treatment with emerging technologies is a practicable solution to improve the efficiency of dye wastewater treatment.
