Abstract

In this paper,the preparation of polymeric silicate aluminum sulfate flocculants and the application in wastewater treatment were studied.The effect of different Si/Al molar ratio was compared and the pH range of this sample in some chemical factory was examined.The results show that the products has good performance when the Si/Al ratio is 1∶1 and the pH value of the sodium silicate is 4～6.The treatment of wastewater has a good effect when the addition is 200 mg/L.
