摘　　要：纺织印染废水来源广泛,组分复杂,目前常用的处理方法主要有物理化学法、化学法和生物法,但这些方法存在运行成本高、工艺流程复杂等缺点。纳米TiO_2多相光催化处理印染废水是近年来研究较多的一项新技术,但存在使用时回收困难等问题,限制了其应用。TiO_2纳米复合纤维密度小、光催化性能高,且易于回收。文中综述了近年来国内外TiO_2纳米复合纤维处理模拟印染废水的研究进展,对提高TiO_2复合纤维光催化性能的机理进行了简要分析,展望了其应用前景。Textile printing and dyeing wastewater has a wide range of sources and complex composi- tions. The commonly used methods to treat printing and dyeing wastewater are combined chemical and physical method, chemical method and biological method. However, these methods have the disadvan- tages of high cost, complex process and so on. Nano TiO2 photocatalytic treatment of printing and dyeing wastewater is a new technology in recent years, but it is difficult to recycle so as to limit its application. The TiO2 composite nano fiber has the advantages of small density, high photocatalytic performance and easily being recycled. The research progress of nano TiO2 composite fiber on the simulated wastewater treatment is reviewed. The mechanism of enhancing the photocatalytic performance of TiO2 composite fiber is briefly analyzed. Its application prospect is also presented.
