摘要
研究了利用硅藻土精制副产的硫酸铝母液生产聚合铝的工艺。合成PAS的条件为 :反应温度 40～ 5 0℃ ,熟化温度 35～ 5 0℃ ,熟化时间 3～ 5h ,稳定剂PE - 2用量为 4%～ 5 %。合成PAC -S的条件为 :反应温度 5 0～ 6 0℃ ,熟化温度 35～ 5 0℃ ,熟化时间 3～ 5h ,CaCl2 /CaO比为 2 .5∶1～ 3∶1,添加剂A -Ⅰ用量为 6 %～ 8%。合成过程简单 ,成本低。
The process of producing polyaluminum from mother liquor of aluminum sulfate produced in purifying of siliceous earth was studied. The conditions for producing PAS were reaction temperature of 40～50℃, aging temperature of 35～50℃, aging time of 3～5h, amount of PE 2 stabilizer of 4%～5%. The conditions for producing PAC S were reaction temperature of 50～60℃, aging temperature of 35～50℃,aging time of 3～5h,CaCl 2/CaO ratio of 2.5∶1～3∶1,amount of A Ⅰ agent of 6%～8%.This synthetic process was simple,and the cost was low.
