    摘要本文用PAC与P(AM-DAC)作为絮凝剂用于双组份模拟印染废水的絮凝研究进行初步探索。以吸光度和Zeta电位为考察指标，对由活性红和活性黑两种活性染料组成0:1,1:3，1:1，3:1和1:0的五种配比模拟印染废水做絮凝脱色研究。探索无机和有机絮凝剂对不同活性染料组成的双组份模拟印染废水絮凝脱色效果及机理推测。无机絮凝剂PAC处理五种配比的混合溶液，活性红染料的最大脱除率分别为98.6%，99.2%,97.5%,96.5%和0,活性黑的最大脱除率分别为0，89.4%，91.9%，93.4%和92.9%。有机絮凝剂P（AM-DAC）处理五种配比的混合溶液，活性红染料的最大脱除率分别为41.1%，65.0%，90.0%，96.7%和0，活性黑的最大脱除率分别为0，0，6.6%，29.0%和53.2%。结果表明，PAC的最大脱除率高于P(AM-DAC)；PAC对活性红组分的絮凝脱色效果优于活性黑组分；当使用P(AM-DAC)絮凝时，活性黑组分将会在活性红组分几乎完全絮凝沉淀后才会开始絮凝。以上研究实验为双组份染料废水絮凝脱色研究和机理探索提供了基础和方向。19048

    Title  The research of two-component dye wastewater flocculating decoloration mechanism
    Abstract 
    Preliminary flocculation research of a two-component simulation of dyeing wastewater was carried out by using PAC and P(AM-DAC) as a flocculant. Using absorbance and Zeta potential as criterions，a flocculating decoloring was be done on five kinds of the two-component simulated with different mass ratio: 0:1,1:3，1:1，3:1 and 1:0 dyeing wastewater  composed of  reactive red dye and reactive black. The decoloring effect of inorganic and organic flocculants on the two-component simulation of dyeing wastewater were researched. By using PAC as flocculent, the most removal rate of reactive red were 98.6%，99.2%,97.5%,96.5% and 0.The most removal rate of reactive black were 0，89.4%，91.9%，93.4% and 92.9%. By using P(AM-DAC) as flocculent, he most removal rate of reactive red were 41.1%，65.0%，90.0%，96.7% and 0. The most removal rate of reactive black were 0，0，6.6%，29.0% and 53.2%. As the result showed, he most removal rate of reactive red was higher than The most removal rate of reactive black; The flocculation effect of reactive red is better than reactive black  flocculated when by using PAC; By using P(AM-DAC) as flocculent, the reactive black component will be flocculated until reactive red had been flocculated completely. The above research results provided the basis and direction of two-component dye wastewater flocculating decoloring research and mechanism exploration.

     1  绪论
         棉、毛、化纤等纺织产品在预加工、染色、印花和整理过程中所排放的废水叫做印染废水，大量产生于工业生产中。印染废水所含物质复杂，芳烃以及杂环化合物为主体，并带有极性和显色基团，还含有起促进染色作用的助凝剂。印染废水的水量总大、COD浓度高、色度高、含多种具有毒性的有机物成分，有较强的抗氧化性、抗生物降解性，已经污染全国各大水域。由于印染废水COD高，而且B/C 值较小，生化性较差；色度高而且组分复杂[1]。
