摘要
以Na_2SiO_3·9H_2O、FeCl_3为原料,应用共聚工艺制备PFSC (聚硅酸铁混凝剂),研究该混凝剂制备的Fe、Si物质的量的比、反应时间、反应温度对其混凝性能的影响。在相同投加量下对含藻水体的混凝处理结果表明,PFSC混凝剂对含藻水的叶绿素a、浊度的去除效果优于市售的PFC (聚合氯化铁)。
PFSC (polyferric silicate chloride) was prepared by copolymerization process with Na2SiO3·9H2O and FeCl3 as raw materials. The effects of the molar ratio of Fe:Si, reaction time and reaction temperature on the coagulation performance were studied. The results of coagulation treatment of algae-laden water at the same dosage showed that the removal effect of PFSC on chlorophyll a and turbidity of algae-laden water was better than that of PFC (polyferric chloride) sold in the market.
