活化硅酸助凝剂在给水处理中的应用研究

The study of the application of the activated silicic acid in drinking water treatment as a coagulant aid

研究了活化硅酸配制和保存的合适参数,并通过试验得到了对于江苏某湖水,活化硅酸的最佳投加量和投加时间。同时进行了生产性试验,并与PAM做了助凝效果和经济效果的比较分析。结果表明活化硅酸具有良好的助凝作用,并在经济性和安全性上优于PAM。

Parameters of preparation and preservation of activated silica is studied. Taking lake water in Jiangsu as raw water, the experiment is carried out to investigate the optimized dosage and dosing time of activated silicic acid. What's more, a full-scale pilot is performed to compare the coagulation effect and economic cost between activated silicic acid and PAM. The results showed that the activated silica, as a good coagulant aid, has the advantages of PAM in cost and security.
