| 摘 要： | 以硅酸钠、硫酸镁和硫酸铝为原料,制备出聚硅酸硫酸铝镁(PAMSS)絮凝剂,将其用于对染料废水的脱色研究.结果表明,SiO2浓度为0.3mol/L,硅酸活化pH=3,活化时间30min,n(Mg)∶n(Si)=1.25,n(Al)∶n(Si)=0.5时,其对活性染料脱色率可达到90%以上.实际废水处理结果表明,PAMSS处理印染废水具有良好的脱色效果,是一种高效的无机高分子絮凝剂.

| Abstract: | The polysilicate magnesium sulfate （PAMSS） flocculant was prepared through sodium sili-cate ,magnesium sulfate and aluminum sulfate as raw materials and it was used for decolorization stud-ies .The results showed that the best condition was 0.3mol/L SiO2 concentration ,pH=3（silicic acid ac-tivated） ,30min activation time ,n（Mg）∶ n（Si）=1.25 ,n（Al）∶ n（Si）=0.5 .Its decolorization rate of re-active dye could reach over 90% .The experimental results indicated the decolorized effect of dyeing wastewater is good if PAMSS was used .PAMSS is a highly efficient inorganic polymer flocculant . |
