摘　　要： 运用 Zeta电位测定技术研究了聚合铝 PAC、聚硅铝 PSA两种不同形态铝盐对漂白废水絮凝反应特性 ,通过絮凝过程中 Zeta电位及傅立叶红外光谱对原水及两种铝盐沉淀物进行了分析 ,结果表明 :吸附架桥为其反应的主要机理 。 The flocculent characteristics of pulp CEH bleaching effluents treated with polyaluminum PAC and polyaluminum silicate flocculent PSA with ζ potentials technique were studied. The structure of sediments produced in pulp bleaching effluents with two kind aluminum salt flocculents was analyzed with IRS. The result showed that adsorption-bridging was the dominant mechanism. The reaction form betweem two kinds of aluminum salts flocculents and the pollutants in bleaching wastewater is the same as the associating form between hydroxy compound aluminum and the hydrogen bond of chlorlignin in bleaching wastewater.
