| 摘 要： | 研究了无机高分子复合絮凝剂聚硅硫酸铁 (PFSS)的制备与絮凝性能。通过对SiO2 的质量分数、铁硅量比、PFSS的 pH值、硅酸活化时间等因素的调整和控制 ,制备出性能优异的絮凝剂。研究结果表明 :w(SiO2 ) =1 4 %～ 2 0 % ,n(Fe)∶n(Si) =(0 8～ 1 0 )∶1 0 ,PFSS的pH =1 5～ 1 8,硅酸活化时间 1～ 18h时 ,可获得絮凝性能优异的无机高分子复合絮凝剂。将制备的絮凝剂用于实际废水样品处理 ,其除浊效果明显优于目前常用的絮凝剂PAC、PFS、FeCl3 、Fe2(SO4) 3 。

| Abstract: | The composite flocculant polyferric silicate sulfate(PFSS) was prepared and the influencing factors of its flocculation properties were investigated. Flocculation effectiveness was tested by determining the turbidity of simulated wastewater.The results showed that the prepared PFSS had best flocculation performance when w (SiO 2) =1 4%-2 0%, n (Fe)∶ n (Si)= 0 8∶1 0-1 0∶1 0,pH=1 5-1 8 and activation time for polysilicate= 1～18 h.By applying PFSS to factual wastewater it was found that flocculation effectiveness of PFSS was better than that of PAC,PFS,FeCl 3 and Fe 2(SO 4) 3. |
