摘要
文中从印染废水的特点、印染废水排放标准、印染废水处理及回用技术等多方面,总结了中国印染废水污染控制现状和遇到的问题。当前为适应用户对纺织产品种类变化的需求,印染废水处理难度不断提高;印染废水处理是一个系统工程,印染生产企业要全面掌握和控制污染物的输入,采用清洁生产的生产工艺和装备,采用绿色的化学品,同时对生产过程中的物料消耗进行有效监控,避免有毒有害污染物输入生产过程;从水污染控制角度,要把以前印染废水末端控制的方式,转变为全过程控制,通过理解和掌握生产过程污染物输入的特点和强度,有针对性地进行污染物控制,优化和开发新的工艺系统,以应对不断出现的挑战。
This paper mainly discusses the current status and challenges of the water pollution control in Chinese textile industry,including wastewater discharge,wastewater characteristics,discharge standards,wastewater treatment and reuse technologies,costs,and emerging contaminants.In order to meet the needs of users for the changes in textile products,the difficulty of printing and dyeing wastewater treatment is constantly increasing,and printing and dyeing wastewater treatment is a systematic project.Printing and dyeing production enterprises must fully control the input of pollutants,and adopt production technology and equipment for cleaner production.Enterprises should use green chemicals,at the same time effectively monitor the consumption of materials in the production process to avoid toxic and harmful pollutants entering the production process.From the perspective of water pollution control,it is necessary to change the end-of-pipe control to the whole process design and control.Through understanding and mastering the characteristics and intensity of pollutant input in the production process,attention should be paid to targeted pollutant control,optimization and development of new process systems to meet the emerging challenges.
