根据纺织印染行业自身的特点,印染废水的处理,应尽量采用重复回用和综合利用措施,与纺织印染生产工艺改革相结合,尽量减少水\碱以及其它印染助剂的用量,对废水中的染料,桨料进行回收. According to the characteristics of textile printing and dyeing industry, the treatment of printing and pvcguancai.89ix.comjinshuguan.89ix.comgaoyaguan.89ix.comtanceqi.89ix.comxguangji.89ix.comjianc eyii.89ix.comdyeing wastewater should adopt the measures of reuse and comprehensive utilization as far as possible, combine with the reform of textile printing and dyeing production process, minimize the amount of water, alkali and other printing and dyeing auxiliaries, and recycle dyes and paddles in wastewater. 例如,对于合成纤维及含合成纤维75%以上的织物采用干法印花工艺,可以消除生产过程中的印花废水;在使用酸性媒染染料过程中,如果用硝酸钠或双氧水代替重铬酸钾全长为氧化剂,就可以消除废水中的铬的污染For example, for synthetic fibers and fabrics containing more than 75% synthetic fibers, dry printing process can eliminate printing wastewater in the production process; in the process of using acid mordant dyes, if sodium nitrate or hydrogen peroxide is used instead of potassium dichromate as oxidant, the pollution of chromium in wastewater can be eliminated. |
