摘    要：含硼聚硅酸硫酸铁(PFSSB)混凝剂具有高效、适用范围广、无毒、适用性强等特点。用水玻璃、硫酸铁和硼砂为原料,SiO₂浓度在3.0%,活化pH=2和活化时间1h等工艺条件下制取含硼聚硅酸硫酸铁(PFSSB)混凝剂。制备PFSSB混凝剂的优化条件为Fe³⁺及SiO₂和B的摩尔比为1∶2∶0.3,最佳碱化度为0.2。含硼聚硅酸硫酸铁(PFSSB)混凝剂处理微污染水源水的最佳投药量为2mL,混凝时间为40min,pH范围为6～8。

Abstract: The polymeric ferric silicate containing boron(PFSSB) is of high efficiency,wide application scope,not poisonous,strong adaptability etc.With water glass,ferric sulfate and borax as raw material,the polymeric ferric silicate containing boron(PFSSB) is prepared under the parameters of 3.0% concentration of SiO₂,activating at pH=2 for 1h.The optimal condition for PFSSB preparation is n(Fe)∶n(SiO₂)∶n(B)= 1∶2∶0.3,the alkalization degree as 0.2.The dosage of polymeric ferric silicate containing boron(PFSSB) for handling the micropolluted raw water is to 2mL,time of coagulating is 40min,the scope of pH is 6～8.
