摘要
将萃淋树脂作为染料捕捉剂应用于印染废水处理中,研究了影响萃淋树脂捕捉分离的各个因素。试验结果表明:萃淋树脂在搅拌速率300 r/min,搅拌时间25 min,恒温70℃,pH值为2.5~3.0,染料与树脂质量比1∶3的条件下,对活性染色废水的捕捉分离效率可达到98%以上。应用于工厂染色废水捕捉分离后,水质色度在10以下,回用后可继续用于染色,且无需再次添加盐分,大大节省水耗及助剂。
Extraction resin is applied as dye-catcher in dyeing wastewater treatment. The factors that affecting on capturing efficiency of extraction resin are analyzed. The results show that when stirring speed is 300 r/min, stirring time is 25 min, temperature is 70 ℃, pH value is 2.5-3.0, mass ratio of dyes to extraction resin is 1 ： 3, capturing efficiency can reach more than 98%. The chromaticity value of the practical dyeing wastewater is below 10, and it can be reused for dyeing without adding salt, which can greatly save water consumption and auxiliaries.
