摘要
实验采用硅酸钠、氯化铝、氯化钙制备聚硅酸铝钙絮凝剂。结果表明,硅酸钠浓度为0.3～0.4 mol/L,活化pH为3～4,活化时间为1.5 h,Al/Si摩尔比为0.8时,Ca/Si摩尔比为0.6时,制备的絮凝剂,除浊率较高。
The polysilicate aluminium calcium flocculant was prepared through sodium silicate,aluminium chloride,calcium chloride as the raw materials.The results show that the removal rate of turbidity was higher when the concentration of sodium silicate was 0.3~0.4 mol/L,activation pH was 3~4,activation time was 1.5h,n（Al）：n（Si）molar rate was 0.8,n（Ca）：n（Si）molar rate was 0.6.
