【摘要】 采用改性双氰胺-甲醛絮凝剂(MDF)分别对含活性染料、酸性染料及分散染料的印染废水进行絮凝脱色实验.考察了MDF在不同投药量、pH值及不同起始浓度下的处理效果.研究表明MDF是一种性能优良的水处理剂.更多还原

【Abstract】 In this paper, flocculating experiments on printing and dyeing wastewater containing reactive-dye, acid-dye and disperse-dye have been carried out using modified dicyanodiamide-formaldehyde flocculant. The flocculation performance in different dosage, pH value and initial concentration of dye was studied. Results showed that modified dicyanodiamide-formaldehyde flocculant was a kind of effective flocculant with excellent decolourization performance.更多还原
