摘要
以铁屑、盐酸和硅酸钠溶液为主要原料,制备聚铁和聚硅酸,并在不同硅铁摩尔比的条件下制备出一系列聚铁硅絮凝剂;将其应用于纸箱废水和卫生纸废水的处理实验可知,当废水pH值为8左右,硅铁摩尔比1∶40的聚铁硅絮凝剂用量为0.20g/200mL废水时,有较好的絮凝效果。用Ferron逐时络合比色法检测聚铁硅絮凝剂的形态分布,同时,也分析了Fe3+的形态分布。
Using Fe,HCl and sodium silicate as the main raw materials,a series of polyferric silicate flocculants （PFCS） were produced under different basicities and the silicon-ferric molar ratio conditions. The better results for treatment of OCC waste water and tissue waste water were obtained when s Si/Fe was 1：40,pH value of waste water was 8 and dosage of the flocculant was 0.5 g/200 mL waste water. The species distribution of PFCS was detected by Ferron timed complex colorimetric method. The Fe （Ⅲ） species distribution characteristic and the factors influencing the species distribution were analyzed. Simultaneously,it was confirmed that the flocculation conditions of the flocculant both in practice and theory agree with each other,the optimal preparing condition of PFCS is Si/Fe=1：40.
