TiO_2光催化氧化法处理偶氮染料废水的研究方法

Methods on Treatment of Azo-dyes Wastewater by Photocatalytic Oxidation with TiO_2

偶氮染料废水是一种有机物含量高、成分复杂、色度高、可生化性差的难降解废水,其处理方法已引起广泛关注。TiO2具有较高的光稳定性和反应活性,是一个能高效光催化降解有机污染物的催化剂。概述了近几年来TiO2光催化降解偶氮染料废水的研究方法。

Azo-dye wastewater is hard to degrade due to its high content of organic compounds,its complexity of the components and high chroma.And its treatment method has been concerned extensively.TiO2 is a highly efficient catalyst which can be used in the photocatalytic degradation of organic pollutants owing to its high light stability and high reaction activity.This paper reviewed the research methods of azo-dyes wastewater by photocatalytic oxidation with TiO2.
