摘　　要：经过两年研究,配制出了pH值9左右、SiO2浓度为2%左右、能稳定保存30d以上的活化硅酸助凝剂。实验室小试表明,助凝剂合适的加入时间为混凝剂加入后约30s左右,最佳投加量为40kg/kT,水温较低时效果显著,投加助凝剂时,混凝剂为硫酸铝时的效果比聚合氯化铝时的效果明显。The coagulation aid, An actived silicic acid, was investigated from 2003 to 2004 at pH 9.0, concentration of SiO2 2%, It could be preserved stably more than 30 days, The expzrimental results showed that proper additive time was 30 seconds after putting coagulation aid, the optimal dosage was 40kg/Kt, the effect was obvious at lower temperature, result of alum was better than poly aluminium chloride with adding coagulation aid.
