摘要
印染废水是日常生活中存在比较普遍的工业废水,它的来源分布广泛,对水体的构成具有严重的污染性并且在环境中不易被处理或转化,因此对环境的治理带来了巨大的困难和挑战。本文重点介绍离子掺杂光催化法、复合半导体光催化法、纳米二氧化钛光催化法、贵金属修饰二氧化钛光催化法、新近改性二氧化钛光催化法降解纺织印染废水的工艺研究。综述了国内外先进的降解实例,比较和分析了各种方法的可行性,并对印染废水的处理进行了总结和展望。
Textile printing and dyeing wastewater is a common industrial wastewater in daily life,with a wide distribution and serious pollution to water bodies.Its treatment poses great difficulties and challenges to environmental governance due to its difficulty in being processed or converted in the environment.This paper focuses on the technological research of degrading textile printing and dyeing wastewater,including ion-doped photocatalysis,composite semiconductor photocatalysis,nano titanium dioxide photocatalysis,noble metal-modified titanium dioxide photocatalysis,and newly modified titanium dioxide photocatalysis.It reviews advanced degradation cases at home and abroad,compares and analyzes the feasibility of various methods,and summarizes and prospects the treatment of textile printing and dyeing wastewater.
