| Abstract: | This article presents a new type of inorganic polymer flocculant,which was prepared using sodium silicate,ferric sulfate,aluminum sulfate and sodium borate as raw materials.Studied the effect of flocculation kinetics.When the pH of the coking wastewater is about 8.0 and the dosage of PFASSB is 10 mg/L,the removal rates of turbidity are over 98%.Moreover,the mechanism of flocculation is discussed preliminarily. |
