摘要
介绍了印染废水的水质特点及回用难点,详细介绍了印染废水深度处理回用技术,如膜分离技术、吸附法、絮凝法、高级氧化技术和生物滤池,并列举了各类技术的研究进展或工程实例。指出选择适当的组合技术能够有效降低印染废水中的各类污染物含量,使之达到某些印染工艺用水的回用要求。
Described the quality characteristics of dyeing wastewater and recycling difficulties, detailed the advanced treatment and reusing technologies of dyeing wastewater, such as membrane separation, adsorption, floeeulation, advanced oxidation and biological aerated filter, and listed the research progress or engineering examples on all types of technologies. Also pointed out that selecting appropriate combination technologies can reduce the content of all kinds of pollutants in dyeing wastewater, so as to reach the requirements about recycling water in a certain printing process.
