Abstract:

The industrial dross containing a lot of Feions and coalash containing many Alions can be used to sy nthetize PAFS.The synthetic PAFS can be used to make a coagulation test on the Huanghe Water which has high turbidity.The optimal feeding amount added to the Huanghe water is studied.It is compared with two kinds of flocculants, market-sold PAFS and PAFC.The result shows that the synthetic PAFS has the best f locculating efficiency.This kind of flocculant should be further developed and spread.

Key words: polymeric aluminum ferric sulphate, coagulation, flocculat ing property

摘要：

工业废渣———物料一含大量铁离子 ,粉煤灰含较多的铝离子 ,用一步合成法可合成聚合硫酸铝铁PAFS。用合成的PAFS对浊度较大的黄河水做混凝实验 ,研究了适宜投药量 ,并与市售的两种絮凝剂进行比较。实验结果表明 ,合成的PAFS絮凝效果良好 ,值得进一步研究和推广。
